Shenzhen Zhiboxin Circuit Board Co., Ltd specializes in PCB, PCB solution and PCB assemble service. We focus on quick-turn prototype and mass production for 2-30 layer boards (HDI, blind / buried hole, high frequency, metal based (Alum based, Cu based) ,we are able to manufacture high quality PCB compliant with SGS and UL certification as well as the ISO9000 quality system.
Our businesses extend far into Asia, Europe, America and Australia etc. Through the cooperation with developed countries’ customers, we have had adopted international advanced technology and management system, and we have improved our technology level from their high standard and strict quality requirements. A new plant is under construction to meet the increasing demands.
Since the establishment, we have been in pursuit of diversification. Based on the principle of complementing one another, the leaders of our company set the goal of “based on PCB production, developing diversity, offering one-stop service”.
