What we have for PCBA?
Kingsheng’s manufacturing is based on lean manufacturing principles and, printed circuit board assembly (PCBA) operations are optimized to meet a high mix of products of wide-ranging complexity and volume. Process validation occurs at each step of production. Lot traceability is central to our processes and quality initiatives.
Kingsheng PCBA runs four SMT lines on a 4-shift basis. One line is dedicated to prototype assembly. Our proto team validates processes, creates programs and work instructions for each product prior to transferring it to a production line. Kingsheng  utilizes Heller reflow technology and DEK screen printers, with HawkEye inspection capability. Each line is equipped with YesTech Automated Optical Inspection (AOI) equipment. We place over one million BGA components each year. Kingsheng has the capability to place up to .3mm pitch components. A Teradyne Summit 750 machine is utilized to perform BGA rework to the 7711 and 7721 standard, ensuring reliable and repeatable performance.
