If you want to learn more about Seagate PCBs, read this guide.

What Is A Seagate PCB?

The Seagate PCB is a product that finds use in storage devices such as Festplatte.

You find the Seagate PCB permits electricity to flow between numerous components that enable the hard drive to perform.

On a Seagate PCB, there are several chips, including one that holds software with a number of drive-specific features.

These features include spindle speed, voice coil voltage, head-to-head ratio, and other data essential to the drive’s functionality.

How Do You Fabricate A Seagate PCB?

Fabricating a Seagate PCB is an intricate process that employs computer controlled applications and special machines.

You find the following steps useful in the fabrication of a Seagate PCB:


Seagate PCB-Herstellung begins with a design which involves the designer creating a blueprint for the PCB.

You find this blueprint meets all of the specifications with the software Extended Gerber often employed.

Extended Gerber is a great piece of software for PCB design because you can also use it as an output format.

This software allows you to encode all of the information you require, including copper layers, solder masks, and additional component nomenclature.

Design Check

After encoding your Seagate PCB design blueprint using the Extended Gerber software, you check double-check the board aspects for faults.

Another check, the Design for Manufacture (DFM) check, guarantees that the PCB design meets the necessary the manufacturing tolerances.

Drucken des Designs

You employ a plotter printer in creating a Seagate PCB film which is essentially a picture negative of the board.

You employ two ink colors to depict the PCB’s inner layers as follows while reversing this tendency for outer layers.

  • Black ink for the Seagate PCB’s copper traces and circuits.
  • Clear ink for indicating sections of the PCB that are not conductive.

Every layer of the PCB, as well as the solder mask that goes with it, receives its own film.

After printing, you arrange them and punch a registration hole through for utilization as an alignment guide in later processes.

Internal Layers Copper Printing

Following the printing of the PCB design onto a piece of laminate, your pre-bond it with copper.

You then etch the copper to reveal the earlier blueprint.

You cover the laminate panel with a resist, which is a form of photo-sensitive film containing photo-reactive chemicals.

These chemicals harden when exposed to UV light.

After aligning the resist and laminate you expose them to ultraviolet radiation. The photoresist hardens as the light penetrates the translucent film regions.

You find this denotes copper areas that should be preserved as traces.

The black ink, stops any light from reaching the spots that aren’t designed for hardening for later removal.

You remove any remaining photoresists using an alkaline solution before pressure-washing to eliminate any remaining debris and allow to dry.

The only resist left on the PCB after drying is over the desired copper trace which you inspect for defects.

Inner Layer Etching

Before proceeding with the fabrication of the Seagate PCB, you remove superfluous copper from the core or inner layers.

Etching entails concealing the required copper on the board before subjecting the remainder with a chemical.

You remove unprotected copper from the Seagate PCB using chemical etching, leaving only the amount required for the board.

When fabricating large PCBs which require more copper, you will need more time and/or solvent.

Can You Employ A Seagate PCB In An SSD?

Ja, du kannst.

A Solid-State-Laufwerk (SSD) is a type of storage device that employs integrated circuit networks to store data permanently.

You find SSD storage utilizes flash memory, and serves as supplementary storage in a computer’s storage hierarchy.

SSDs are without the mechanical spinning disks in hard disk drives and the movable heads for read–write in floppy disks.

SSDs offer improved shock resistant, run quietly with faster access times and lower latency than electromechanical drives.

What Drilling Techniques Can You Use On A Seagate PCB?

Drilling is a costly PCB fabrication process that takes time and requires high accuracy because of its irreversibility.

Drilling allows you to furnish your Seagate PCB with vias and through holes offering interlayer connectivity.

You find the following drilling techniques useful in fabricating a Seagate PCB:

Mechanisches Bohren

Mechanical drilling is simple to carry out requiring the use of drill bits.

You can work out a hole diameter of 6 mils when using a mechanical drilling process.

Mechanical drill for PCB

mechanical drill for PCB


Laser drilling offers you increased precision allowing you to create smaller hole diameters of about 4 mils. There is no physical contact of the tool and work piece with this process and you can easily control drill depth.

Where Do You Find Copper In Seagate PCB?

You find copper employed for the conductive path of a Seagate PCB.

The copper network allows you to electrically connect the components on a Seagate PCB.

Seagate PCB

Seagate PCB

You find the use of copper on a Seagate PCB favored for the following reasons:

  • The electrical and thermal conductivity of copper is outstanding.
    Consequently, you observe effective transfer of electrical signals without power loss and heat transfer across the board reducing thermal stress.
  • The impressive electrical transfer property of copper means you only need a small amount to complete the task.
    You can transform a copper ounce into 1.4 mils of thickness, sufficient to swathe a square foot board.
  • Furthermore, copper’s unrivaled thermal resistance and current carrying capability.
    It enhances reliability of the Seagate PCB in drives employed in extreme circumstances.
    Such environments include extremely high or low temperatures and pressures.
  • When you employ copper on your Seagate PCB, you can easily employ a conventional heat sink below it.
    Alternatively, you can design the Seagate PCB such that you employ one side of copper surface as a heat sink.

What Are Some of the Issues That Affect a Seagate PCB?

Some of the common issues that affect a Seagate PCB include:

Übermäßige Hitze

If you do not take steps to provide proper ventilation, the inside of a computer can become excessively hot.

You note this heat can subsequently result in electronic problems affecting your Seagate PCB.

Unsachgemäße Handhabung

Your electronic components can succumb to electrostatic discharge and get permanently destroyed if inappropriately handled.

Before handling a Seagate PCB, always ensure you’re grounded.

Faulty Electrical Supply

A faulty power supply to your computer can cause damage by sending erratic energy levels to components via the motherboard.

You should invest in power supplies of high quality.


Connecting your computer to an uninterruptible power supply safeguards your Seagate PCB from power surge induced damage.

Manufacturing Flaws

Although uncommon, you can find Seagate PCBs with manufacturing flaws overlooked at the testing stage.

Consequently, when you connect your Seagate PCB, some components can malfunction hindering the PCB’s effective performance.

What Are The Failure Symptoms Of Your Seagate PCB?

When a printed circuit board fails, a hard disk will frequently stop working completely.

This isn’t always the case, though and can work normally with intermittent spinning speed bursts and strange noises.

Some common symptoms of failure include:

  • Inability to load your OS where your drive is bootable.
  • Inability to read and write files where your drive is not bootable.
  • Clicking and whirring sounds.

Can You Replace A Damaged Seagate PCB?

You can replace a damaged Seagate PCB but at great risk of losing data in your drive.

You find modern Seagate PCBs, contain distinctive information called “adaptive data” stored on them.

The adaptive data is necessary if you are to successfully recover the data stored on the drive.

In old Seagate PCBs, you could replace a broken PCB with a matching one before powering normally and recovering your data.

However, adaptive data in modern Seagate PCBs is extremely valuable and you simply cannot duplicate. The data recorded on the PCB, is essential for data recovery from the drive.

How Do You Replace A Seagate PCB?

Swapping a Seagate PCB is not a straightforward task with a successful replacement PCB requiring customization.

Otherwise, your drive will malfunction while the data becomes inaccessible.

However, the replacement process involves the following steps:

Understand Your Seagate PCB Firmware

You find the unique data you require to access your storage drive in memory chips on your Seagate PCB.

This information is the PCB firmware and you cannot access your data in its absence.

Consequently, simply carrying out a Seagate PCB swap will not bring a malfunctioning hard drive back to life.

Therefore, it is necessary to transfer the firmware to your replacement Seagate PCB.

Carry Out Drive Diagnostics

You need to actually attribute your drive problem emanates from a damaged Seagate PCB since it could be mechanical.

You can examine the cords that connect the hard drive or whether your HDD is spinning.

Where you have a buzzing sound, it could be a spindle seizure and not a PCB problem.

However, a lack of movement could be indicative of a defective Seagate PCB.

You can also check to see if the BIOS recognizes the drive with corresponding specifications.

You find this can be likely a software issue or failure of the logical drive.

Find Seagate PCB Replacement

You find a replacement for your Seagate PCB only after confirming the problem with your drive results from board damage.

You may find it difficult to get a matching Seagate circuit board for your drive where it is uncommon.

Get A Specific Replacement

The replacement Seagate PCB has to conform to the architecture and design of the damaged board.

For instance, you cannot replace a Seagate PCB of Barracuda design with that of F3 design.

Additionally, there should be a memory chip on your new circuit board on which you’ll need to transfer the PCB firmware.

What Components Can You Find On a Seagate PCB?

You will find the following components on a Seagate PCB:

Mikrocontrollereinheit (MCU)

The MCU is the largest chip of a Seagate PCB and central to all its functions.

You observe an MCU in modern Seagate PCBs typically comprises of a Central Processor Unit (CPU).

The CPU performs all calculations and controls a Read/Write channel that translates analog signals to digital signals and vice versa.

Additionally, the MCU also features IO connections for controlling everything on the PCB and transmitting data through SATA.

Micro controller unit

micro controller unit


The memory chip in a Seagate PCB is usually a DDR SDRAM whose memory capacity determines the drive’s cache capacity.

You find the memory of a Seagate PCB logically separated into two types: buffer or cache memory and firmware memory.




The VCM controller draws the lion’s share of the Seagate PCB’s electrical power.

It regulates the rotation of the spindle motor and the movement of the heads.

The VCM controller core can tolerate temperatures of up to 100 degrees Celsius.

Voice coil motor controller

voice coil motor controller

Blinken (Flash)

You note that a portion of the drive’s firmware is stored on a flash chip.

When you turn on a drive, the MCU interprets the flash contents beginning the code.

In the absence of this code, the drive would not even start.

When there is no flash chip on the Seagate PCB, the MCU holds the content of the flash.

Shock Sensor

The shock sensor detects disproportionate shock on a drive sending a signal in response to the VCM controller.

The VCM controller parks the heads and, on occasion, spins down the drive.

It should theoretically shield the drive from further harm, but it doesn’t in practice and it won’t survive heavy impact.

Shock sensors on some drives can detect even the tiniest vibrations.

Inputs from these sensors would aid the VCM controller in tuning up head movements.

You need at least two shock sensors in such drives.



Transiente Spannungsunterdrückungsdiode

The TVS diode is a protection device that safeguards the Seagate PCB from external power source power spikes.

When a TVS diode detects a rush of electricity, it burns up. You note that this causes a short circuit between the power connector and the ground.

Transient voltage suppression diode

transient voltage suppression diode

Why Are Seagate PCBs Rigid?

A starre Leiterplatte is one that you cannot forced out of form by bending.

Once you make a rigid PCB, you cannot adjust or fold it into any other shape.

You find Seagate PCBs are rigid circuit boards allowing them to be furnished with increased density and high quality.

Additionally, providing a rigid Seagate PCB is cheaper and more durable compared to a flexible board.

What Materials Do You Use in Making Seagate PCBs?

You find the following materials useful in the fabrication of Seagate PCBs:


You find FR-4 widely employed as a Seagate PCB substrate material.

Impressive thermal, electrical, and mechanical properties, in addition to superior strength-to-weight ratio, make FR4 materials appropriate for Seagate PCBs.

When making FR-4, you note the use of glass cloth and epoxy resin which keeps the cost low.

FR-4 is common for Seagate PCBs with low layer counts, such as single and double-sided boards.


When you employ polyimide laminates, you achieve better thermal performance than FR-4 material, in addition to marginally better electrical performance.

Polyimide materials are more expensive than FR4 but provide better resistance to severe and high-temperature conditions.

You find polyimides exhibit increased robustness during heat cycling with minimal expansion characteristics.

Consequently, you find their use prevalent in Seagate PCB constructions with a higher layer count.


Laminates and bonding materials derived from Teflon have outstanding electrical characteristics, making them perfect for high-speed Seagate PCBs.

Teflonmaterialien cost significantly more than polyimide, however, their high-speed characteristics are desirable.

You can coat Teflon on glass cloth, as an unbacked film or with particular fillers and additives to increase mechanical qualities.

When manufacturing Seagate PCBs using Teflon, you need specialist personnel, and dedicated equipment and processing.

What Etching Processes Does Seagate PCB Employ?

One of the most important procedures in the processing of a Seagate PCB is etching.

During etching, you eliminate excess copper revealing the ideal circuit layout of your Seagate PCB.

You can employ the following three different PCB etching procedures listed below:

Chemisches Ätzen

Chemical etching is a subtractive manufacturing technology applied more often on metals in which you use chemical baths.

You remove the metal during the operation in order to generate metal pieces with the required shape and thickness.


You employ a high-powered laser to inscribe the Seagate PCB’s trace lines in the laser etching process. You can easily use computer aid in this etching process.

It allows you to reduce the number of stages while eliminating ink usage and other harmful chemicals such as acids.


You use a high-speed stream of glow discharge (plasma) of a suitable gas combination focused towards the material in this process.

The process involves selective etching of material by interaction with chemically active radicals.

Compared to conventional wet, chemical etching procedures, plasma etching is dry and clean, simplifying the process and improving dimensional tolerances.

Plasma etching allows for precise and controlled etching while reducing the likelihood of via contamination and absorption of solvent.

Is Impedance Matching Important In Seagate PCB Design?

Impedance matching in Seagate PCBs addresses energy transport, where the load impedance has to match the transmission line’s characteristic impedance.

You find no transmission-related reflection at this time, indicating that the load has absorbed all of the energy.

Transmission, on the other hand, results in energy loss while signal quality of the Seagate PCB depends on the impedance matching.

What Factors Do You Consider When Designing A Seagate PCB?

The following factors are essential when designing a Seagate PCB:


You need to consider all aspects of your Seagate PCB including electrical component arrangement, stacks, layers, crosstalk budget among others.

The design factor also includes performance of a DFM check to ensure you can manufacture the PCB.


You find two common storage drives that employ the Seagate PCB: the hard disk drive (HDD) and Solid State Drive (SSD).

The HDD magnetically stores data employing rotating disks for the data reading and writing process.

SSD employs flash memory composed of discrete memory cells that hold bits instantaneously accessible via the controller.

You find an SSD minimizes the form and size of drives by eliminating the HDD’s movable parts.


Creation of an outstanding Seagate PCB design, requires prioritization of signal integrity.

For signal integrity, you analyze the signal’s rise and fall, characteristic impedances, and track lengths.

You can verify excellence of your Seagate PCB design by undertaking signal integrity simulations done before and after layout.


A breakout strategy is essential in verification of the breakout process and routing of a Seagate PCB with high pin-count.

You find determining the breakout pattern is necessary for signal verification and power integrity.

The breakout strategy will also help you decide on utilizing micro-via brackets and their depth.


Vias come in a variety of shapes and sizes, and allow you to interconnect electrical components in different Seagate PCB levels.

You consider a Seagate PCB with the fewest vias as a good design as it demonstrates efficiency.

Power Integrity

You may find Seagate PCBs employed in devices requiring high currents at low voltage owing to high performance levels.

You have to closely monitor the AC and DC performance of the circuit as it influences the system’s power distribution network.

How Can You Test A Seagate PCB?

Fully assembled Seagate PCB

Fully assembled Seagate PCB

Some of the tests you can carry out on a Seagate PCB are:


This test entails the use of fixed probes arranged in a fashion that matches the Seagate PCB’s design.

The ICT equipment presses the board against the bed of probes which check the solder connection’s integrity.

The ICT testing probes can connect to the circuit using predesigned access points on the board.

They apply some pressure on the connection to ensure that it remains unbroken.

Fliegende Sondenprüfung

The flying probe test is a non-powered test type that employs needles on a probe arranged in a computerized two-dimension grid.

You use this test to check the Seagate PCB for opens, shorts, resistance, capacitance, inductance and diode issues.

Automatisierte optische Inspektion (AOI)

AOI takes images of the PCB with either a 2D camera or pair of 3D cameras.

After that, the computer compares your board’s images to a thorough schematic.

If a board does not match the schematic to a particular extent, you tag it for inspection.

AOI can be helpful in discovering problems early so that production can be stopped down as soon as possible.

Always use AOI alongside another test such as a flying probe test or ICT.

Does A Seagate PCB Employ Silkscreen?

Das Seidensiebdruck is the top layer of a PCB, serving as a guide for on board component arrangement.

The silkscreen specifies helpful information on a Seagate PCB board that might aid or benefit users during assembly.

You find the silkscreen provides information on component values, part numbers, test points, and polarity, among other things.

What Surface Finishes Can You Employ On A Seagate PCB?

Oberflächenbeschaffenheit der Leiterplatte

Oberflächenbeschaffenheit der Leiterplatte


HASL is the most common surface finish in the PCB industry.

Here, you immerse the Seagate PCB in a trough containing molten tin/lead alloy.

You then employ ‘air knives,’ to remove excess solder by blowing hot air across the board surface.


Immersion Tin involves the direct application of a tin coating over the Seagate PCB’s copper through a chemical displacement reaction.

The copper and tin form a strong bond with the finish securing the copper from oxygen-induced corrosion.

Organic Solder Ability Preservative (OSP)

OSP protects the copper surface from corrosion by depositing a thin protective coating of material over it in a conveyor zed process.

You employ a water-based organic chemical forming a selective binding with copper and an organometallic layer that shields the copper pre-soldering.

How Much Does A Seagate PCB Cost?

You find Seagate PCBs with different prices with most ranging between ten and thirty dollars.

Many factors affect the price of a Seagate PCB especially the component density and their respective capacities.

You will find basic Seagate PCBs costing less than five dollars.

Seagate PCBs intended for high-performance use can cost you over fifty dollars.
