Multilayer circuit board builds & sequential bonding

The first question must surely be why do we need to multilayer a circuit board? The answer is, as with a plated board, to allow more interconnection routes for the designer. As components have become smaller with more connections required, the routeing just gets more and more difficult. When I used to explain plated through […]


Design for manufacturability

I am not sure who came up with the word manufacturability but I like the word, it may have even been me. It describes the ability to manufacture and if a circuit is able to be manufactured easily, it has a cost and quality implication. If you are putting pencil to paper or mouse to […]



A Grand Day Out with Clarydon and Steve Stockley (50!)

It has been 20 years since a young man of 30 set up a business to supply PCBs to the electronics industry. To celebrate the founding of the company and the coinciding birthday, do the sums yourself, Steve invited everyone in the workforce to a grand day out in London. So, on Thursday the 5th […]

Etching undercut

Thank you for your emails and memories of good old solder finishes but I opened up a question by mentioning undercut and a few of you have asked for a bit of background. Undercut is relatively easy to explain in that when a copper sheet is chemically etched, it is done with a bank of […]


Surface finish on bare printed circuit boards

For those of us who can, let us cast our mind back to the days when 12 thou gap and track was still a technological challenge and there was a rumour someone could drill and plate 0.6mm diameter holes. Surface finish was simple in those days. You had roller tin for single sided complete with […]
