What is PCBA?

PCBA, which stands for Printed Circuit Board Assembly, is a critical component of electronic devices, comprising printed circuit boards, electronic components, and solder. It provides circuit connections, protects components, and facilitates heat dissipation. The manufacturing process involves steps such as PCB design, fabrication, component placement, soldering, and testing.

PCB Assembly (PCBA) Process

Design review and component control

Procure electronic components as required according to the Bill of Materials (BOM), ensuring their quality and compatibility.

Solder Paste Printing

In PCB assembly, solder paste is applied to the pads to prepare for the soldering of surface-mount components (SMDs).

SMD Component Placement

Surface-mount components (SMDs) are accurately placed onto the solder paste using a pick-and-place machine.

Reflow Soldering

The PCB with through-hole components is passed through a wave soldering furnace to create reliable electrical connections between the component leads and PCB pads.

Through-Hole Technology (THT) assembly

Use automated insertion equipment to place through-hole components into pre-drilled holes on the PCB.

Automated Optical Inspection (AOI)

Check if the components are correctly placed in their designated positions, ensuring there is no displacement, misalignment, or omission.

X-ray Inspection.

Inspect the internal structure of solder joints to identify potential soldering defects, such as voids, cracks, insufficient solder, and solder bridges.

Functional testing

Conduct electrical and functional tests on assembled PCBs to ensure proper operation.
