Post-Processing Steps and Considerations in High-Frequency PCB Production
I. Main Post-Processing StepsSurface Cleaning Step: After processes like electroplating, etching, and soldering, high-frequency PCBs may have chemical residues or contaminants. Use ultrasonic cleaning, chemical cleaning, or high-pressure water cleaning to remove these residues and ensure the PCB surface is clean.Consideration: Ensure that the cleaning agent does not damage the PCB surface. Surface smoothness is […]
