SMALL-BATCH PCBA & PRODUCT DEVELOPMENT

Your idea. Your next batch.
Our engineering support.

From a few prototypes to hundreds of assembled boards, we help niche product makers and R&D teams bring electronics from concept to finished product.

Discuss your project

Based in Zhuhai, China. We combine in-house PCBA production with PCB design, firmware development, and final product assembly.

No minimum order quantity. Start with the quantity your project needs, then return for repeat small-batch production.

PCBA manufacturing

Component sourcing, SMT, through-hole assembly, and final assembly are handled in-house. We focus on flexible production for prototypes, custom products, and small batches.

Hardware & software

PCB design, microcontroller firmware, and simple PC applications help move your project from an initial concept to a working product. App development can be coordinated with external partners.

Finished-product support

Enclosure assembly, testing, and packaging, with supply-chain support to help optimize cost. Established partners provide plastic and metal 3D printing, CNC machining, and plastic injection tooling.

Planning your order

With materials ready, up to 10 PCBA samples are typically completed within one week; standard larger orders take around two weeks. Final timing depends on quantity and complexity. Sample orders may include engineering fees; design and complete-product schedules are quoted separately.
