The package of flexible circuits

Posted by on August 13, 2006 No comments

The most common package of flexible circuits(FPC) is using the paper strips to fix on the rigid board. Every part is to pile up 10~20pcs flexible circuits together. We should avoid using tape, because if the chemical substances in the tape adhesives oozes, the terminal would be easy to be oxidized and change color. The base material is polyimide which is easy to absorb moisture.

The flexible circuits together with silica gel, etc. the drying agents have to be put into the polythene bag and sealed. Then put it into the cartons together with cushion material.

Due to special shapes of Flexible PCB, we should adopt different packages according to different shapes.

Lead-free and environmentally of circuit boards

Posted by on February 18, 2006 No comments

We know in the industry, the tin-lead is a very important material. However, due to “Electronic Information Products Pollution Control Regulations” (hereinafter referred to as “RoHS”), as well as the implementation of related environmental laws and regulations, contain lead six kinds of hazardous materials, substances or processes will be banned, as contained in SnPb solder high levels of lead which will be gradually banned. In the electrical and electronic manufacturing, ranging from materials to components to the component and then to machine equipment and related upstream and downstream close to the lead-free process of changing the most critical aspect is the component part made of circuit boards.

As a leading manufacture of flexible circuit  and printed circuit boards, all of our boards are lead-free. Please let us know if you need more information.

What’s the NRE fee for my circuit board?

Posted by on July 29, 2005 No comments

NRE fee means Non-Recurring Engineering fee, you will only pay one time charge for your custom spec. circuit boards. NRE fee including tooling, engineer and testing fee.

We do not charge NRE fee for mass production and neither do we charge the fee for the reordered for production.

I think you are clear about the NRE fee now. If you need more information, please contact us.
