What Topsearch does

Topsearch is a privately held Hong Kong-headquartered printed circuit board (PCB) manufacturer founded in 1985, with 40 years of operating history and consolidated production at a 1.5 million-square-foot-per-month facility in Shaoguan, Guangdong, China. The company manufactures multilayer PCBs ranging from 2 to 28 layers (production capability 18 layers, prototype 28 layers), with specialization in HDI (High Density Interconnect, including CO2 laser drilling down to 2 mil), heavy copper (up to 6oz production, 12oz pilot), VOP/VIP (via-on-pad plugging), and hybrid construction combining Rogers high-frequency laminates with FR4. Its technology stack also includes in-house testing (flying probe, universal grid testers) and process automation (auto-drill maximization, laser-assisted layup), with R&D partnerships with Hong Kong Polytechnic University and Tsinghua University supporting advanced process development.

The company sells primarily through a global direct sales model, with sales offices in the US, UK, Singapore, Taiwan, Malaysia, Thailand, Japan, Korea, and Eastern China, supplemented by over 17 representative offices in major markets. Revenue is generated via direct hardware sales of PCBs, priced on a quote basis determined by layer count, materials, technology, and volume. Customers span automotive (BMW, Volvo, Volkswagen, Geely, Land Rover, Buick, Opel, Johnson Electric), medical (Roche, Stryker), telecommunications (Avaya, Lancom), industrial (Hitachi, KUKA), electronics (Toshiba, Sony), and Tier-1 EMS providers (Flex, Jabil, Celestica, Sanmina, Wistron, Benchmark Electronics). The company holds ISO 9001, ISO/TS16949:2002 (automotive quality), and RoHS compliance certifications.

Topsearch's recent strategic posture emphasizes upmarket technology migration (HDI and heavy copper focus from 2017-2024) and geographic diversification into Southeast Asia and North America (announced for 2025), building on its 2007 consolidation of Shekou operations into the Shaoguan facility. The legal structure spans three entities: Topsearch Printed Circuits (QuJiang) Ltd. (China, manufacturing), Topsearch International (Holdings) Ltd. (Hong Kong, headquarters), and Topsearch Printed Circuits Macao Commercial Offshore Company Limited (Macau). Ownership is private with no disclosed external investment or parent company.
