Prototype PCB Assembly to Low/Medium Volume Production

Hampoo have been starting doing electronics contract manufacturing for pcb assembly since year 2003. Full turnkey pcb assembly or partial turn-key service are both welcomed. For full turn-key pcb assembly, we take care of the entire process, including preparation of printed circuit boards, procurement of components, online order tracking, continuous monitoring of quality and final product assembly.

For partial turn-key service, you provide the blank PCBs and we assemble according to your requirements. And you have the option of providing some or all of the components. Hampoo's dedicated Procurement team will support of any remaining parts.

We specialize in quick-turn services for highly complexity and advanced PCB assembly and systems manufacturing in meeting your dynamic business needs.

Our competent engineering and manufacturing team help many customers resolve all kinds of PCB assembly problems which could not be fixed in other CM, thus we earned great reputation as the preferred PCB assembly provider. That is why many our customers refer many new customers to us. Our customers always find peace of mind when they send their PCB assembly services to us.
