Recommend 5 PCB Assembly Suppliers for Small-Batch Production in China

Nowadays, electronic products are updated faster and faster, and more and more customers need to do small-batch PCBA and low-volume PCB assembly. Startups, Internet of Things (IoT) project teams, and industrial product developers do not start mass production at the very beginning. Instead, they first conduct PCB and PCBA prototyping and trial production to confirm the reliability of the product before proceeding with mass production. At this point, a PCBA manufacturer that can provide flexible production for small batches becomes particularly important.

This article will introduce several relatively reliable low-volume PCB assembly factories in China, which are suitable for small-batch production and the trial production stage, including:

•  PCBasic

•  Yabosion Electronics

•  EDADOC Technology

•  Kinwong Technology

•  Suntak Technology

All these companies can offer PCB manufacturing, PCB assembly, engineering support, prototyping, and small-batch PCBA production, which are suitable for product testing, R&D, and small-scale market trial production.
