Our rigid PCB products cover 1-30 layers and are widely used in industrial control, power supply, national defense, medical, automotive, security, computer and other fields. The main rigid printed circuit board product types include single-sided PCB, double-sided PCB, high-end multilayer PCB, HDI PCB, high-frequency PCB(Rogers PCB, Taconic PCB, Arlon PCB), Hybrid PCB, metal core PCB, rigid-flex PCB etc., and our special PCB technology that can process include thick copper, resin plugged holes, control depth routing, countersink, countersunk, press fit holes, PCB edge plating, blind & buried vias, half plated holes etc. We can also design and develop new processes according to customer product needs. To meet the personalized process and quality requirements of customers' special pcb products.
