Over a decade of precision electronics manufacturing, built on our own production lines, delivering reliable PCBA services to clients worldwide.
SHENZHEN SUNWIN ELECTRONICS TECHNOLOGY CO., LTD. (Sunwin) is a PCBA manufacturing and electronic module solutions provider. The company is backed by its own production base — Shenzhen Saketron Electronics Technology Co., Ltd. — established in 2009, with over 8,000 square meters of production space and 21 high-precision SMT lines, specializing in the development and mass production of compact, high-precision, modular electronic products.
Sunwin uses SMT + COB hybrid processes to provide full-cycle PCBA services for clients worldwide — from component sourcing and SMT assembly to chip packaging and final testing — across optical communication modules, RF and wireless communication modules, and custom module product lines such as wearables and consumer electronics, backed by more than 15 years of industry experience.
Unlike a pure trading supplier, Sunwin operates a real, self-owned SMT factory, giving us direct control over process consistency, lead time and quality stability — the foundation for serving clients who need high precision across small and frequent batches.
From equipment configuration to quality systems, Sunwin is fully equipped to take on high-precision, modular product manufacturing.
PCB fabrication, component sourcing, SMT, packaging and testing under one roof.
Combined surface-mount and chip-on-board processes for high-precision, miniaturized products.
Full-process SPI / AOI / X-Ray / ICT / FCT inspection with MES traceability.
