Thick copper PCBs, with their high current carrying capacity, excellent thermal management performance, and enhanced mechanical strength, play a significant role in industrial automation, industrial robots, power supply systems, and renewable energy systems. However, the manufacturing process of thick copper PCBs is far more challenging than that of ordinary PCBs, requiring overcoming challenges in material selection, lamination, drilling, and routing.
LT Circuit's two 4-layer through-hole thick copper boards, with inner 3 outer 10 and inner 6 outer 6 copper thicknesses, demonstrate its technological prowess in the thick copper PCB field. These two heavyweight products, with a combined inner and outer copper thickness exceeding half the product thickness, showcase LT Circuit's expertise in material selection, lamination, drilling, and routing.
