Whenever we've made a PCB we've always had to create a library of custom layouts - even when the PCB software includes libraries of common components from a variety of different manufacturers.īecause we're getting to like DipTrace very quickly and plan to use it for all our PCB work in the immediate future, the first thing we need to do is re-create our library of custom layouts. This is because most PCB packages use "standard" pins and pad sizes, which - while fine for mechanised pick-and-place and SMT soldering machines - can be a nightmare to solder by hand. Whenever we design and layout PCBs for homebrew manufacture, there always comes a time when we have to undo a great deal of work, and amend the footprints or patterns for the components on the PCB layout.
