We produce BT-core-pcb-samples. the materials has 4 colour. Like: white (colour). yellow. lack. nd gray. we use BT materials to produce small pad gap. small spacing line to line PCB. we have higher Capability technical.
To produce small spacing pcb. with Blind vias and Buried holes. from 2 layer to 50 layer. we produce BT core pcb samples. and batches order. you can send us your pcb gerber files. and BT material’s request. our engineer will help you to get a quote. send us your pcb gerber files please. and BT material’s request. we will help you to get a quote.
