Circuit Board Fab

KART specialized in supplying all kinds of PCB (printed circuit board) to customers all over the world, from one layer to 28 layers, especially on the high density circuit board with special material like High Tg FR4, Hagolen free FR4, Rogers,PTFE and Micro wave material.   

Facility locates in Shajing with 200 staff, the monthly capability is 20000 square meter, 4 layer boards and above account about 50%, other is 2 layers and 8, 10 layers with buried via, blind via, impedance. During the production, AOI is used to check the circuit in order to ensure the PCB quality.  
KART has also met the highest international manufacturing standards by being approved for these quality certificates: ISO9001, ISO14001, TS16949. We are UL certified for single sided, double sided and multilayer PCB production, and adhere to all of the requirements for IPC and RoHS standards.
