While low-cost professional PCB fabrication has largely supplanted ... a soldermask and silkscreen to his homemade boards. The process he describes starts after the board has already been etched.

This can become a problem; if the process is not tightly controlled, the etching reactions can extend underneath the resist layer masking off areas of the future traces of the PCB, potentially ...

This new handbook contains more than 650 PCB process defects ... drilling, surface prep, etching chemistries, lamination, final finishes, etc.—and summarizes causes and solutions for each.

One of the main challenges is the control over the etching process, particularly in terms of the etch rate uniformity, surface roughness, and feature size variability. The development of advanced ...

While this may sound like a simple scaling down of a PCB for installation onto a meta-PCB, it’s not quite that easy. Any such assembly process requires inspection and test for quality assurance, but ...
