PCB Assembly Service

Solder Paste Printing

Process Description

Apply solder paste precisely to SMT pads using stencil alignment, ensuring consistent volume and clean pad definition.


Key Technical Requirements

Laser-cut stencil accuracy; controlled paste viscosity;
2D/3D SPI inspection; uniform deposition.

PCB Assembly Service

SMT Component Placement

Process Description

Place SMD components at high speed with vision alignment to ensure accuracy for fine-pitch and miniature packages.


Key Technical Requirements

Optical centering; feeder calibration; fine-pitch handling (BGA/QFN/01005); placement accuracy control.

PCB Assembly Service

Reflow Soldering

Process Description

Melt solder paste under controlled thermal profiles to form strong joints without damaging heat-sensitive components.


Key Technical Requirements

Multi-zone temperature profiling; peak temp control; nitrogen atmosphere (optional); thermal soak/cooling control.

PCB Assembly Service

Through-Hole Assembly (THT)

Process Description

Insert leaded components manually or via automation, followed by wave or selective soldering for reliable joints.


Key Technical Requirements

Proper lead forming; wave height control; selective solder parameters; solder fillet & hole-fill requirements.

PCB Assembly Service

Cleaning & Finishing

Process Description

Remove flux residues and apply optional conformal coating for added protection and long-term reliability.


Key Technical Requirements

Ionic contamination limits; ultrasonic/aqueous cleaning; controlled coating thickness; masking critical zones.

PCB Assembly Service
