CNC Machined SMT Fixture Precision Assembly Service for Complex Double Sided Boards

CNC Machined SMT Fixture Assembly for Complex Boards

Warped or irregular boards fail in reflow because nothing holds them flat, which is why we machine SMT fixtures on our own CNC equipment. QHPCBA is a precision PCB assembly manufacturer based in Shenzhen, China, focused on quick-turn SMT assembly and small-batch PCBA production for global hardware startups, R&D teams and OEM manufacturers. With our own SMT laser stencil workshop and an independent CNC fixture workshop, we respond faster, solve production issues in-house, and keep every prototype moving.

Fixtures Machined In-House

Our independent CNC fixture workshop machines support pallets, carrier fixtures and custom tooling designed around each board outline. This keeps odd shapes, cut-outs and thin panels stable on the line.

• CNC machined support and carrier fixtures
• Tooling for irregular PCB outlines
• Double-sided assembly support
• Fast fixture iteration when a design changes

Stable Placement on Difficult Boards

A rigid, well-aligned fixture improves placement accuracy and reflow quality, particularly for double-sided builds where the second pass must not disturb the first side.

• Improved positional accuracy
• Reduced board warpage in reflow
• Reliable second-side processing
• Consistent batch-to-batch results

One Workshop, Fewer Delays

By machining fixtures ourselves, we remove the external supplier queue that usually stretches complex assembly schedules by days.

• No fixture outsourcing delay
• Rapid re-machining after revision
• Complex assembly support
• Prototype to small-batch coverage
