Printed circuit board is an indispensable electronic component in commonly used electronic products in our daily life. Its usage rate is high, such as computers, mobile phones, TVs, refrigerators, air conditioners, computers, etc., which appear in The electronic products in our lives all need circuit boards, so from the side, its appearance also facilitates our daily lives.
