Cooling for Power Boards
Heat is a common problem for power engineers. Boyastar's factory is in Guangde, Anhui, China. The plant covers 19,000 square meters. We have more than 150 employees. We produce about 50,000 square meters of PCB each month. Our end products reach more than 170 countries. The Multilayer Power PCB service is built for heat and large current problems. This board fits power modules, switching power supplies, communication power supplies, and industrial power supplies. Communication power, industrial power, server power, medical power, LED driver power, charging pile power, energy storage power, and inverter power are all within our experience. We use high TG FR-4 as the base material. We support 4 to 20 layer multilayer lamination. Thick copper carries large current. High TG material handles high heat.
Stack-Up and Current Design
High CTI FR-4 is optional. Impedance control, blind and buried vias, and BGA are all available. Immersion gold, HASL, and OSP are common. Immersion silver, immersion tin, and hard gold plating are also supported. Large-current boards, low-heat boards, and long-life boards can be sent as Gerber files. Our engineering team has more than ten engineers. They help with stack-up design. They calculate current carrying capacity. They send a formal quote and lead time within 24 hours. We accept OEM and ODM orders. We build from drawings or prototypes. Layer count, stack-up, board thickness, copper thickness, base material, surface finish, solder mask color, silkscreen color, impedance, thick copper areas, and packing all follow buyer requirements. Power boards are sensitive to temperature rise. Our engineers calculate trace width and copper thickness based on current. The board stays within temperature limits at full load. Communication power and industrial power need long-term reliability. We run temperature cycle tests on every batch.
Temperature and Current Tests
Heat is the top risk for multilayer power boards. We run temperature rise tests, current carrying tests, and impedance tests. We confirm the first article before release. We keep records for every step from incoming material to final shipment. Our quality team has more than 20 people. Every board gets electrical testing before packing. We use AOI optical inspection and flying probe testing. We accept third-party inspection. Our factory holds IATF16949, ISO9001, ISO14001, and ISO45001. We hold Underwriters Laboratories product safety certification. The file number is E528398. The Multilayer Power PCB service helps buyers meet European and American market requirements.
