What Safety Precautions Should You Use When Using Epoxy When Making An Epoxy Resin PCB?

There are several safety measures that you should undertake when you are fabricating an epoxy resin PCB.

This is because you are using epoxy resin as one of the fabrication materials when making the printed circuit board.

The first step you need to do is put on gloves that will protect your hands from being exposed to the epoxy resin.

One of the recommended gloves that you need to put on your hands is Nitrile gloves.

Besides, you can use other simple substances such as baby wipes to eliminate the epoxy resin if it contacts your skin during the fabrication process.

For the epoxy resin that remains on your skin, you can remove it using water and soap mixture.

Also, you need to wear a plastic apron when fabricating an epoxy resin PCB.

This is because the plastic allows the easy removal of the epoxy resin substance if it happens to spill on the apron.

Also, put on safety goggles as they will protect your eyes.

If the epoxy resin contacts your eyes, you should use clean water to flush your eyes for almost 15 minutes.

In addition, do not rub your eyes during this process, and afterward, you can seek medical attention at the earliest convenience.

The last step entails fabricating the epoxy resin PCB in a location that has ample ventilation.

This is important as it ensures clean circulation of air within the work area.

For instance, you can ensure that you open the windows or turn on fans within your work area to assist with the air circulation.

Also, you can put on a respirator in instances where the circulation of air is insufficient due to one reason or another.

Can You Use Various Types Of Epoxy Resin When Making An Epoxy Resin PCB?

The epoxy resin that you can use when fabricating an epoxy resin PCB can fall into two distinct categories.

Dazu gehören folgende:

  • Non-glycidyl

In this category, you can find the following subcategories:

This type of epoxy resin will fall under the umbrella of the following:

  1. Glycidyl-ether, which happen to the most popular epoxy resins that you will use when fabricating epoxy resin PCB
  2. Glycidyl-amine
  3. Glycidyl-ester

Here are some of the types of epoxy resins you can use when manufacturing an epoxy resin PCB:

  • Bisphenol Epoxy Resin

One of the most popularly epoxy resins for commercial production of epoxy resin PCB is DGEBA [Bisphenol-A diglycidyl ether].
