About JS

Established in 2007, Jiu Shuo Co., Ltd. (J S Company) began by trading electro-deposited copper foils for printed circuit board (PCB) clients. After more than a decade’s efforts, we have become a specialized provider of bespoke-sized electro-deposited copper foil. Our core customers include PCB and also copper clad laminate (CCL) manufacturers, and lately for lithium-ion battery as well.

We have partnered with renowned Taiwanese copper foil manufacturers who are experienced and have in-house professional R&D teams. They use state of the art production equipment, with main processing carried out in clean room facilities to ensure strict quality control of copper foil products.

As the company grew, we increasingly appreciated the important role that good quality and production flexibility play in modern-day business competition. After witnessing and observing the various needs and receiving much feedback from customers, we have our own square sheet cutters and splitting machine.

Tailor-made length and size copper foil supplied in a timely fashion

Today as a professional copper foil cutting and slitting provider, we supply tailor-made lengths and sizes (sheets) of the 4oz, 3oz, 1oz, 2oz, 1/2oz, 1/3oz and other copper foil products, based on the customer’s production needs, which are sold to domestic and foreign PCB, CCL, and lithium-ion battery manufacturers.

Being an integral part of the copper foil supply chain also helps us further solidify our partnership with our up-steam copper foil suppliers. As a result, we are uniquely able to supplement their slitting and cutting needs according to the specific length and size as requested by their customers; exactly the same specialized service as we offer our customers.
