Abstract

The invention relates to a two-sided flexible printed circuit (FPC) roll-type material-receiving production process. The two-sided FPC roll-type material-receiving production process comprises the following steps: flexible copper clad laminate (FCCI) piece cutting; FCCI drilling; FCCI developing; receiving materials, wherein the material of the receving material is an epoxy glue series covering membrane; roll-type baking; roll-type copper plating and later making. According to the two-sided FPC roll-type material-receiving production process, an epoxy glue series covering membrane is adopted to replace an acrylic adhesive series covering membrane which is adopted by the prior art, and the two-sided FPC roll-type material-receiving production process has the advantage that the price is relatively low. According to the two-sided FPC roll-type material-receiving production process, not only pollution to environment can be avoided through avoiding using halogen, but also good electroplating performance and chemical liquid-resisting performance are achieved. Further, due to the fact that the step of roll-type baking is added correspondingly, the binding force is much good, and tensile property of products becomes much good too.

Description

technical field [0001] The invention relates to the field of flexible circuit board production, in particular to a double-sided FPC roll-type splicing production process. Background technique [0002] The traditional double-sided flexible circuit board (FPC) roll operation process is as follows: figure 1 As shown, including: cutting FCCL (soft copper foil substrate, English full name: Flexible Copper Clad Laminate) into slices, slice drilling, slice development (Shadow), splicing, coil copper plating, and then It is made after entering, and the receiving material mostly adopts acrylic glue-based covering film, which is relatively expensive; it contains halogen, which has certain pollution to the environment; some receiving materials are attacked by wet process potions, and the receiving part There will be poor material breaking, which will cause the finished product to be scrapped; some of the connecting materials have poor electrical conductivity, and the copper thickness ...
