FPC flexible circuit board production process
FPC flexible circuit boards have a very wide range of applications. Some circuits and electronics are used in automobiles. There are double-sided and single-sided flexible circuit boards. The production processes of single-sided and double-sided flexible circuit boards are different. The following is The corresponding production process.
FPC double-sided circuit board production process:
Cutting→Drilling→PTH→Plating→Pretreatment→Applying dry film→Aligning→Exposure→Developing→Graphic plating→Removing film→Pretreatment →Paste the cover film→Pressing→Curing→Immersion of nickel gold→Printing characters→Cutting→Electrical measurement→Punching→final inspection→Packing→shipping
FPC single-sided circuit board production process:
Cutting → drilling → sticking dry film → alignment → exposure → developing → etching → stripping → surface treatment → covering film → pressing → curing → surface treatment → immersion of nickel and gold → printing characters → cutting → electrical measurement → punching Cutting→final inspection→packaging→shipping
The production process of FPC flexible circuit boards is roughly as described by the circuit board manufacturers above. Although there are differences between single-sided and double-sided, the principle of production is still the same.
