Building Products - Low Volumn Construction

Try drilling the holes first. Then all you have to do is connect the dots if you are using a Dalo Pen. It's also easier to line up any artwork.

Make soldering as easy as possible and allow easy access to the pins to be soldered by:

If you have components that need soldering on both sides but you cannot, on IC sockets for example, try creating a via as close to the component as possible. Just use a small piece of tinned copper wire and solder it on both sides of the board.
Keeping a component raised off the board slightly so you can solder the top side
Use a wire wrap socket with long pins.
Bending IC socket pins at right angles to solder on the top side.
Mounting components underneath the board.
Create a through hole socket out of machined IC pins.
