Have you ever encountered a problem where the three-proof paint on a circuit board is difficult to remove, affecting the normal operation of the circuit? Worry not, as today I'm here to share how to easily remove the three-proof paint from a circuit board.

Before removing the conformal coating, it's crucial to understand its composition. Generally, conformal coating is made from high molecular materials such as polyurethane and epoxy resins, and thus requires the use of professional adhesives removers or paint strippers for removal.

Firstly, we must select the appropriate desoldering agent or cleaning agent. There are numerous brands and types of desoldering agents or cleaning agents on the market, and it's essential to choose based on the material of the circuit board and the composition of the three-in-one coating. Generally speaking, opting for environmentally friendly desoldering agents or cleaning agents that do not harm the material is a safe and reliable choice.

Next, we must apply the adhesive or paint stripper evenly onto the circuit board, allowing a few minutes for the adhesive or paint stripper to react thoroughly with the protective coating. During this process, it's crucial to control the time to prevent the adhesive or cleaning agent from excessively eroding the circuit board.

Dip Stripper is a strong oxidizing agent that can completely oxidize and decompose three-proof paint, rendering it non-adhesive and easily removable. When using dip stripper, safety precautions must be taken to avoid contact with skin and eyes.

By following these steps, we can easily remove the three-proof coating from the circuit board. It's important to be cautious and careful during the process to avoid damaging the circuit board.
