This is the second version of my PCB business card, meant either for production at a PCB manufacturer, or perhaps for production in my "back yard" on a two layer PCB using the toner-transfer method. Having had little success with the toner-tranfer method of etching "home-brew" PCBs, and in need of having a "living" business card ASAP, I ordered a small run of these boards from PCBWay. So far, the boards appear to be working out quite well. This version does have vias, however, and is also a two-layer PCB, so this will make the "home-brew" method challenging at best. However, given that this would normally be my first approach (i.e. to prototype the PCBs at home to test out whether or not the concept works before ordering PCBs from a PCB manufacturer), it is unlikely that this version will ever be etched at home. I will continue to create new versions of my PCB business card, adding complexity and functionality as I see fit over time. So it is likely that this version of my PCB business card has reached its full maturity, and will not continue to be worked upon.
Given that this was the first PCB that I have created using CircuitMaker which has actually made it to being produced, this was also my first opportunity to learn the good, the bad, and the down-right ugly of having a community-based approach to creating componnets for the library. The good, of course, is that with a community contributing to the library, the chances that you will find the component that you need will be quite reasonable. And over time, these chances will tend to increase considerably. The bad is that there is no consistency or standardization in either schematic symbol or [more importantly] PCB foot-print creation between like/similar components (e.g. two 100 ohm, 1%, 1/8W, 0805 resistors). The ugly is that one will learn only too late (e.g. while attempting to solder components to the board) when inferior footprints have been used in one's design. I realize that different foot-prints are optimized for different manufacturing/assembly methods, but obviously for the purposes of most of my designs, I am looking for components that can easily be hand-soldered. So I will need to be more careful in my selection of components in the future.
