Anatomy of a CX500 Cdi unit

Double sided boards are more involved in that to make contact between the two sides, you either need PTH (plated through holes), which are beyond the scope of most hobbyists, or solder short pieces of wire between the layers.

+1 (there are also some little rivet things you can get to do through hole) Philips used to use them a lot. If you are serious look out for a second hand UV light box on eBay. There are some cheopo ones with UV LED's nowadays ... not tried them but that's not to say they don't work fine.
Mike is right that double sided are a bit more complicated but if you have access to a decent laser printer I can talk you through a fairly painless way of making them. Surprisingly, the double sided photo-etch board isn't that much more expensive relatively than single sided. I also use a dip tinning solution to 'tin' the copper after etching to give much better solderability and corrosion resistance.

Just a couple of components to still arrive & fit but essentially rebuilt with 2017 spec parts and vastly superior spec. CDi capacitors. only bits retained were the Thyristors and thermistors but these were full tested in a separate jig and were fine. Once it's working though, I will investigate alternatives just in case anyone reads this in the future and wants to replace them in their unit.
