Through Hole PCB Assembly for Wave and Selective Soldering

Through Hole PCB Assembly for Wave and Selective Soldering

Huayihai provides through hole PCB assembly for connectors, power components, and parts that require mechanical strength on the board. Assemblies are built according to customer Gerber files, BOM, and technical specifications.

Through-hole joints are completed through wave soldering, selective soldering, or manual soldering, depending on the board design and component layout.

Custom Manufacturing Only

We provide through hole PCB assembly according to customer Gerber files, BOM, and technical specifications. We do not supply ready-made or standard products.

FAQ

Q1: Can you handle boards with both SMT and through-hole parts?

Yes, mixed technology assembly is a standard part of our workflow.

Q2: When is selective soldering used instead of wave soldering?

When heat-sensitive or tall components must be protected, or when only part of the board needs through-hole soldering.

Q3: What is the largest board you can assemble?

Up to 900 × 600 mm, with board thickness from 0.5 to 6.0 mm.

Q4: What files are required to start?

Gerber files, the BOM, technical specifications, and quantity requirements.

Q5: How is lead time determined?

3–5 working days for samples and small batches, after file review is complete.
