We insist that "value is immeasurable".

  The engineering team with some forty, fifty staff has enabled us to reach over 6,000,000 pieces of Memory Module in April 2000. In comparison to the monthly sales volume of 10,000,000 PC, our production has obtained a quite large proportion. The only reason is that everything is made of little components. Though PCB is tiny, it is a critical element for operation. Though Brain Power is a aggressive company, we firmly control the thickness, precision for measurement and surface finish. This is why you can rely on us.


Thickness Control
  For SDRAM, DDR and RAMBUS DIMMPCB, either 4, 6 or 8 layers structure, the tolerance is +4 mil, this is the most difficult task. With self-designed thickness categorization system, we categorize the inner layer material and prepreg by thickness in order to reduce errors and to control the structure thickness after lamination under the tolerance. For better performance, we produce millions of memory module PCB monthly for flexible utilization after categorization.

Surface Finish
  In response to different requirement of DIMM PCB for surface finish, complex metal finish is also one of our strength. For example, selective gold plating with OSP / ENTECH, HASL or IMMERSION NICKEL/GOLD are in mass production. The manufacture process for selective gold plating with immersion silver or immersion tin is still under research, aiming to reduce environmental pollution.

CNC ROUTING
  When in the routing module, patented automatic unload machine will be used. After routing, the PIN used to fix PCB on CNC will sink to allow DIMM PCB to be placed on the table. The error will be reduced to 1mil with the PIN being automatically removed.

CARBON EMBEDDED
  This what makes us proud. With thick film technology, we have successfully printed 70 buried resistors. This breakthrough has reduced the assembly time by at least one third, winning warm acclaims from the clients. One out of very two pieces of DIMM PCB we produce now uses buried resistor. Our clients include world's top 5 memory module suppliers. Buried carbon resistor with thin film technology with higher reliability is still under development. Once we succeed, the tolerance will be controlled to under 5%.

PRECISION IN MEASUREMENT
  A special laminate is custom made according to different needs. The exterior adopts extra fine FR4 cloth to substantially reduce the unevenness between the wrap and weave. Currently, the maximum resistant temperature of laminate and glass are far lower than that at the assembly location. The CTE value of copper and fiber glass cloth with epoxy resin are different by more than ten times, therefore, copper needs to undergo a rather large pulling force. How to prevent trace from breaking, increase the reliability during assembly and application of PCB are highlights of the engineering team's tasks. As well as detail pre-production inspection by the CAM station on mechanical weak point of the trace, regular inspection of the plating thickness, eliminate all factors causing nicks on trace such as defect on film, dirt on exposure unit, peak and dent on copper to selecting high glass temperature laminate while necessary.
  Mature technology in the sophisticate market is the goal of our engineering team. We emphasis on thorough research, more breakthroughs on grounds of mature technology in order to provide perfect products. Moreover, we provide design support to work with our clients to produce special flow products. With our diligent attitude and close cooperation with our clients, we will accomplish our goals and create new market opportunity.
