10+ years connecting global buyers with quality electronic components and assembly services.
Gain Technology HK Co., Limited (首信實業有限公司) was established in 2016. Headquartered in Hong Kong with operations in Shenzhen — the heart of China's electronics industry — we are an independent distributor of electronic components and a provider of SMT assembly services.
We specialize in supplying hard-to-find, obsolete, and allocated components that authorized distributors cannot deliver. With 1,000+ parts in ready stock and a global network of trusted suppliers, we help factories, design houses, and fellow traders keep their production lines running.
Beyond components, our SMT assembly service offers a one-stop solution — from component sourcing and PCB fabrication to assembled, tested, and delivered boards. This means our customers work with a single partner for their entire electronics supply chain.
Simple principles that guide every transaction.
We never sell counterfeit or remarked parts. Every component goes through incoming inspection — visual check, marking verification, and functional testing when required. Our reputation depends on it.
We reply to RFQs within 2 business hours. In-stock items ship the same day. When your production line is stopped waiting for a part, every hour counts — and we know it.
We don't chase one-off deals. We build relationships — many of our customers have been with us for 5+ years. Fair pricing, honest communication, and reliable delivery keep them coming back.
Components or assembled boards — we handle both. Instead of managing multiple suppliers for parts, PCB, and assembly, you work with one team that understands your entire project.
