What should happen after PCB design?

The PCB design is complete, all the DRC checks are done. Hours of pouring over every part of the design by you and your colleagues have been made to make sure the latest electronic baby is as good as it’s going to be. What comes next?
There are many, many articles about different aspect of the printed circuit design process, or the bare board
fabrication do’s and don’ts. Very little is written about post design, this could be because it’s the boring bit that no-one wants to talk about because it’s as
much fun as being poked in the eye. But capturing design intent at this point is key, or the you could be doing it again sooner than you think.

Let’s assume for the purpose of making this a little easier to swallow that the basics like silk colour, solder resist and stack up etc etc are all documented on one of the design layers as they should be and the library components are tried and tested. All the gerber files have
been generated and are sitting there. What other documentation is needed?
1) Netlist
2) Component positions data
3) Assembly drawings
4) Build instructions
5) Important component information
6) Other special requirements
Designers and engineer’s know there are times when things have gone wrong because some key information is missing. It’s unreasonable to expect the companies making our boards to notice the unusual or to mind read our intentions. The good companies
sometimes pick up on those things that seem strange and ask for clarification, but relying on this is dangerous. What’s the simplest way of finding out what’s needed? Do what most engineer’s hate – pick up the phone and talk to them, if that’s too painful there’s good old email. The key thing is to ask them and find out.
