Precision starts long before the PCB reaches final inspection.
In this process, solder mask ink is applied to the PCB surface through screen printing, creating the foundation for reliable solder mask coverage.

A stable solder mask process helps ensure:
• Consistent coating thickness
• Accurate pad and via definition
• Better protection against oxidation and contamination
• Improved insulation between conductive features
• More reliable downstream assembly

For high-density, multilayer, impedance-controlled, and high-reliability PCB projects, every manufacturing step matters — including processes that may appear simple from the outside.

At ShinE PCB, we focus on process control from material preparation and imaging to solder mask, surface finish, electrical testing, and final inspection.

Because PCB quality is not created at the final QC station.
It is built into every process.
