Precision SMT Board Assembly Custom CNC Machined Fixture Service for Fine Pitch Work

Precision SMT Board Assembly with Custom CNC Fixtures

When component spacing shrinks, accuracy depends as much on tooling as on the machine, so we combine precision placement with CNC machined fixtures. 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.

Accuracy From Tooling and Process

Custom CNC fixtures hold each board flat and aligned so fine-pitch placement lands correctly and stays put through reflow.

• Custom CNC machined fixtures
• Fine-pitch alignment control
• Stable placement through reflow
• Repeatable positioning accuracy

Fine Pitch and Small Components

We routinely place 01005 and 0201 chips and fine-pitch ICs, with paste printing controlled by stencils cut in our own workshop.

• 01005 / 0201 chip placement
• QFN and BGA assembly
• In-house laser stencils
• Clean lead-free joints

Verified After Every Pass

Precision is confirmed, not assumed. AOI and X-Ray inspection close the loop on every build.

• 100% AOI inspection
• X-Ray for hidden joints
• Functional test available
• Documented results
