Rigid flex circuits have been used in the military and aerospace industries for more than 20 years.Rigid flex circuits combine the best of both rigid boards and flexible circuits integrated together into one circuit. The two-in-one circuit is interconnected through plated thru holes. Rigid flex circuits provide higher component density and better quality control.

After coating process, the exposed copper conductor surface of FPC may have adhesive or ink pollution, oxidation and discoloration caused by high temperature process. 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.
