Customer want to make double-sided FPC and hope the copper width as thin as possible. The smallest thickness of double-sided base material is 12.5um PI, the copper thickness is 12um, the finished copper thickness will be 18-20um after plating. After negotiation, we changed it to single-layer flex PCB to meet customer’s requirement, the base material is 12.5um PI, the finished copper thickness is 12um.
Customer have typically ordered from places in the past, but now customer would like to do a few custom colors that they don't offer, particularly gray, orange and the matte colors. That's exactly what we can do.
