Heavy Copper for High Current
The Thick Copper BMS Circuit Board service is built for battery management systems. Copper thickness goes from 0.5 oz all the way to 6 oz. This is the key standard for this board. Our factory is in Guangde Economic Development Zone, 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. This board sits inside a battery management system. It serves the main control, slave control, voltage collection, and current collection. Its core strengths are large current flow, low heat, and long life. We use high TG FR-4 as the base material. We can do full-board thick copper and partial thick copper. The high-current channel uses thick copper. The signal area uses normal copper thickness. This keeps current capacity high and cost under control. High CTI FR-4 is also available for high-voltage environments.
Surface Options and Engineering Review
This board supports immersion gold, HASL, and OSP as common surface finishes. Immersion silver, immersion tin, and hard gold plating are also available. We support impedance control, blind and buried vias, and BGA. This board fits electric vehicle BMS, hybrid vehicle BMS, energy storage BMS, home energy storage, commercial and industrial energy storage, and base station backup power. Buyers who need high-current boards, thick copper boards, low-heat boards, or long-life boards can send Gerber files. Our engineering team has more than ten engineers. They review current carrying capacity. They give cooling advice. They send a formal quote within one day. They also assess the lead time with the files. We accept OEM and ODM orders. We build from drawings or prototypes. Copper thickness, thick copper position, layer count, board thickness, base material, surface finish, solder mask color, silkscreen color, impedance, and packing all follow buyer drawings.
Heat Tests and Full Traceability
Heat is the top risk for thick copper boards running large currents. We run temperature rise tests, current carrying tests, and heat resistance tests. The first article must pass before the batch moves forward. We keep records for every step from incoming material to final shipment. Our quality team has more than 20 people. Every board gets 100% 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 Thick Copper BMS Circuit Board service gives buyers a strong path for high-current battery management designs.
