In order to get attached the coating of good adhesion, the conductor surface contamination and oxide layer must be removed to keep surface clean. It can be said that the pre-treatment cleaning process will have a significant impact on the basic characteristics of the flexible printed circuit board, you must pay full attention. </p><p><img src="https://file.allpcb.com/bbs/17/05/06/183405907.jpg"/></p>
