Our 5-Step SMT PCBA Assembly Process

Step 1: Free DFM & DFA Review

Our engineers analyze your Gerber files and BOM before a single board is built, identifying footprint mismatches, trace width issues, and stack-up concerns. This free review saves thousands of dollars in costly respins and production delays down the line.

Step 2: Smart Component Sourcing

Step 3: Precision SMT Placement & Soldering

Step 4: Rigorous Multi-Stage Inspection

Step 5: Functional Testing & Delivery

Frequently Asked Questions

What is SMT PCBA assembly and how does it differ from THT assembly?

SMT (Surface Mount Technology) PCBA assembly involves mounting electronic components directly onto the surface of a PCB using automated pick-and-place machines and reflow soldering. THT (Through-Hole Technology) inserts component leads through drilled holes and solders them on the opposite side. SMT allows for smaller, denser boards, while THT provides stronger mechanical bonds for certain components. Many modern boards use both — known as mixed assembly.
