Processing ofITEQ IT-158Laminate Inner Layers

Take and find an ideal first round (compensation for dimension) before initiation of mass production.

Subject the PCB material to brown oxides or black oxides treatment, then bake it at 120°C for 40 minutes.

The lamination process MUST not exceed 195°C if brown oxides are used.

Lamination of ITEQ IT 158 Material

Prepare your stacks in the lay-up room to prevent moisture absorption.

Subject stacks comprising core and prepreg to vacuum processing for 30 minutes before heating.

The pressure range should vary between 350 to 400psi for hydraulic and between 300 to 400psi for vacuum hydraulic.

Heat the stack at between 80°C and 140°C at the rate of 1.3-1.8°C/min when using Lien Chieh Machinery.

Alternatively, heat the stack for between 1.5-3.0°C/min at 80°C and 140°C. In both cases, maintain the cooling rate below 3.0°C/min.

During the pressing cycle, hold the board for at least 60 minutes when its temperature reaches 180°C.

This technique helps you confirm that Tg is above 150°C and that change in Tg is below five degrees Celsius after pressing.

ITEQ-IT 158 PCB material’s compatibility with lead-free processing temperatures is doesn’t depend on its lead content.

However, it relies on the ‘maximum safe temperature’ of the product.

Lead-free soldering techniques follow the use of specific solder alloys.

These type of alloy exposes the laminate to higher temperatures during assembly than traditional SnPb solders.

The higher temperatures are a result of the higher melting points of metal alloys used for lead-free solders.

Remember, the higher temperatures also cause the Reflow and rework operating temperatures to rise.

Below are some of the lead-free solders and corresponding assembly.

Also, you will find reflow temperatures that you can consider for your operations.

Generally, the reflow of lead-free soldering techniques ranges from 230°C to 250°C.

Preis

Compared to other laminates with similar properties, IT158 is very cheap and pocket-friendly.

As a result, you can use it to produce high-quality, affordable end products.

Materialverfügbarkeit

Please inquire with your supplier whether they can timely and reliably deliver the product’s desired quantities without failure.

Plan appropriately to avoid delays and shortages.

If a single supplier cannot meet all your demands, opt for ordering from multiple suppliers where appropriate.

Protection to the Environment

Some applications demand the use of laminates which are eco-friendly and safe for human health.

ITEQ IT-158 PCB laminate comes in handy under such circumstances, given that it is RoHS compliant and is Sony Green Bool Certified.

It also meets all the ISO 45001:2018 standards, indicating that its production was safe and secure.

How Can you Store ITEQ IT-158 PCB Laminate?

Store IT 158 prepreg and laminates in a cool and dry place to avoid deterioration arising from product oxidation and corrosion.

You should maintain a storage temperature below 20°C and humidity below 50%.

Release the prepregs exposed to humidity to minimize absorption of moisture.

Always store rolls and panels of prepreg and laminates horizontally to avoid damage associated with vertical stacking.

Ensure that the storage surface is flat and free from dirt.

Dirt can cause scratches on the surface of the prepreg and laminates.

Storage on non-flat surfaces can also cause the laminates to bend.

Do not remove the original sealing when storing the panels.

It protects the laminates against potential corrosion, oxidation, and any other mechanical damage.

The storage shelves should be large, extending beyond the surface area of the laminate.

Interleave your laminates with non-abrasive, soft separator sheets.

When storing ITEQ IT-158 laminates in their original shipping boxes, stack the boxes on flat surface with the heaviest at the bottom.

Also, do not place too much weight on top of the lower boxes.

This can cause the ITEQ PCB materials to disintegrate and damage the content laminates.

What are the Best Handling Practices when Working with ITEQ IT 158 PCB Laminate?

Good ITEQ IT-158 laminate handling practices are mandatory and must-follow steps to avoid potential damages.

The following tips can effectively help protect the laminate’s integrity.

  • Pick the thinner laminates using two edges to avoid distortion, given that they lack the ability to self-support.
  • Transport your laminates on flat carrying trays while interleaved with soft, non-abrasive materials.
  • Maintain the original laminate seals during the initial processing procedures
  • Always wear gloves, eye goggles, and protective clothing when machining IT 158 PCB material.
  • Maintain a clean, dry, and well-ventilated working environment.

Is ITEQ IT 158 PCB Material Fire Retardant?

Yes, ITEQ IT 158 PCB laminate is resistant to fire, with UL94 V-0 rating.

Consequently, according to this rating, IT 158 PCB material must meet the following conditions:

  • Individual test specimen(s) must not burn for more than 10 seconds following the initial and second flame application.
  • The total burning time for each set of 5 specimens should not exceed 50 seconds for ten flame applications.
  • Besides, the burning and glowing time following the second flame withdrawal should be more than 30 seconds.
  • Drips of flames from the burning specimen must not ignite a cotton battling placed at 300 mm below the test specimen.
  • The specimen must not completely burn or burn with flaming combustion up to the holding clamp.

How Can You Design an ITEQ IT 158 PCB?

You can use the Stackup Pro web tool provided and hosted by ITEQ Corporation on their website to design your IT 158 PCB.

This web-based tool helps you design the best arrangement of copper layers and insulators that best suit your application’s needs.

It will automatically work out the expected PCB’s inbuilt press thickness and impedance.

It also edits your design and alerts you in case of any prepreg layer insufficiency.

Why Should You Import ITEQ IT 158 PCB Material from China?

You are assured of product authenticity.
