Accuracy, productivity and value to meet the changing needs of today and tomorrow. With the most comprehensive, diversified offering of best-in-class products, resulting in increasing yields and lower operating costs.

At Graperain, doing business means more than just closing a deal. It means developing long term relationships and earning client trust. That is, listening to our customers and responding quickly and precisely. Whether you are an existing customer or new to our process, you will see immediately benefits from choosing Brain Power to fulfill your PCB needs.

Excepting OEM PCB, i.e. Telecommunication, PC Add-On Card, IT Application, Network Device, Multi Layers FR-4 product, we have some outstanding products as follows:

1. Carbon Built on PCB: Apply for Thick Film Technology to make the PCB with buried resistors or touch pad function. It is to reduce cost and increase productivity without any function lessened. We have achieved the filed in memory module PCB and touch pad.

2. Thin PCB

3. CSP // BGA PCB: Because the chipset supports high frequency, many requires BGA package, i.e. AGP card, DDR 400 etc. We understand that it is not only for surface flatness, but also for filling VIA holes. Those kinds of PCB are increasing and we expect the quantity will be over 30% of our production in coming years.

4. Special Service: In addition to devote in normal PCB process, our engineering team also provide design support as requested by clients. With cooperation, we complete special process products such as PCB for mobile phone battery with gold wire bonding. The key point is that the surface of the plating needs to be very smooth to reduce the friction between the battery with the mobile phone and the charger. The number of rubbing might be over thousands of times within the battery's shelf life. Therefore, we tailor made a laminate for this PCB, the exterior is extra fine FR-4 cloth to substantially reduce the unevenness of the wrap and weave.
