Topfast Capabilities

CAPABILITIES

PCB One-Stop Solution Service Step by Step

PCB manufacture include inner/outer imaging, plating, AOI (Automated Optical Inspection), solder mask application, and surface treatment.

Inner/Outer lmaging
The process of transferring the PCB design onto copper-clad laminates using photoresist and UV light.
Plating
The process of adding a thin layer of copper to the board, which is then etched to form the conductive pathways.
AOI (Automated Optical Inspection)
The use of machine vision systems to detect defects or errors in the board after the manufacturing process.
Solder Mask
A layer of polymer applied to the board to protect the copper traces from oxidation and prevent solder bridges during assembly.
Surface treatment
The process of applying a layer of metal to the exposed copper traces to improve their conductivity and protect them from oxidation.
