We make high-precision single/double-sided and multilayer PCB (layer 1-16) combining the technologies of high Tg thick copper plating, hot air leveling, gold-plating, electric gold Plugs, and Teflon coating. Besides,our PCBs also cover highly-complicated back board, PCMCIA and semi-plate special board. Special materials like aluminium metal,ceramic substrate, high-frequency PTFE sheet are widely used for HDI boards and a variety of customized PCBs.
