How to eliminate the protection of IC on the circuit board paint
Circuit board: Printed Circuit Board (PCB), also known as circuit boards, PCB board, aluminum plate, high frequency board, ultra-thin circuit boards, ultra-thin circuit boards, printing (copper etching technology) circuit boards.
his paint is treated at high temperature and is treated with solder resist. General chemical solvents can not be dissolved. Scratch or wipe off. With fine sandpaper.
The circuit board mainly consists of pad, through hole, mounting hole, wire, components, connectors, filling, electrical boundary and so on. Common board structure includes single layer PCB (single Layer PCB), double board (Double Layer PCB) and multi-layer board (Multi Layer PCB) three.
