Who we are

One-stop printed circuit board assembly solutions since 2012. From Shenzhen headquarters to manufacturing in Jiangmen and Thailand, we support customers with connected engineering, sourcing and production.

We provide complete PCB assembly services.

Since its establishment in 2012, KeepBest has developed service capabilities across the electronics manufacturing value chain—from component procurement, SMT assembly and DIP insertion to finished-product assembly, testing and ODM support.

We work with international brand owners in robotics, consumer electronics, automotive electronics and power tools, combining responsive communication with coordinated manufacturing in China and Thailand.

More than a factory: an accountable partner from early engineering to delivery.

Our value

Three advantages that support customer success.

The original KeepBest promise, presented more clearly for international engineering and purchasing teams.

One-stop support from R&D to mass production

We participate early, help reduce repeated samples and support the path from initial prototypes through trial and volume production.

Flexible and fast support

Built for customized products and orders that may be smaller, more varied or more urgent than traditional mass production.

Experienced international communication

Our team understands global customers' quality expectations and the importance of clear, responsive cross-border communication.
