Heavy Copper for Vehicle Power
The Automotive Thick Copper PCB service handles large current loops in vehicles. Copper thickness goes from 0.5 oz to 6 oz. Boyastar has built circuit boards for 18 years. We own more than 25 patents. We add 5 to 10 new process patents each year. Thick copper is one of our strengths. This board fits automotive power modules, motor drives, BMS, and DC-DC converters. On-board chargers, lighting power, air conditioning power, and audio power also use this board. 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 gets thick copper. The signal area keeps normal copper thickness. This keeps current capacity high and saves cost. High-current boards, low-heat boards, and long-life boards are all within our experience.
Materials and Cooling Advice
High CTI FR-4 is available. We support impedance control, blind and buried vias, and BGA. Surface finishes include immersion gold, HASL, OSP, immersion silver, immersion tin, and hard gold plating. Buyers can send Gerber files. Our engineering team has more than ten engineers. They review feasibility first. They send a quote and lead time within 24 hours. They also give current carrying capacity advice and cooling suggestions. We accept OEM and ODM orders. We build from drawings. Copper thickness, thick copper areas, layer count, board thickness, base material, surface finish, solder mask color, silkscreen color, impedance, and packing are all negotiable. Partial thick copper is popular with automotive buyers. It adds copper only where large current flows. Other areas keep normal copper thickness. This controls board weight and cost.
Current Tests and Full Traceability
Heat is the top risk for thick copper boards. 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 batch gets 100% electrical testing. We use AOI 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 Automotive Thick Copper PCB service gives buyers a strong path for high-current vehicle power designs.
