Technology Roadmap
China Printed Circuit Board manufacturer SAYFU will invest both advanced equipments and human resources to develope capacity to meet the world PCB technology requirements, and cator for the quick turn PCB oritention. With more than 10 years experience and developement, our tenology team has learned mature capacity for all kinds of PCB, flexible pcb, rigid-flexible pcb etc. You can see some special technologies showing as below.
For each year, one team, including CAM,MI,Processing engineers will be sent to other PCB factories to study advanced technology and management concept. We have set up communication agreements with pcb factory like SCC, Fastprint, Suntak etc. Those enterprises are successful ones in high multilayer pcb, and quick turn prototype.
