So I created this little project to have a board that disassembled and could be soldered together to create a solid 10-6 pin ISP converter. Knowing this was a probably not going to work, I sent my design to OSHpark to test the limitations. Pictured above is start to finish of what I wanted and what I received.
In doing this I was able to determine a couple things many of which I’m sure are a no brainer to those experienced individuals. Never the less I hope it proves useful to the less experienced.
- Carefully consider the size of drill tooling when designing your board. You’ll notice I was trying to get small gaps that were too small.
- Also with tooling size into consideration, you will not be able to get squared off edges notched into your board. Drill bits are round and will make rounded notches on your board.
- If you want to do something super fancy like soldering pieces of pcb together using pads at the edges of the board. Make sure the pads are big enough to get a good solid connection with both boards. Also consider the minimum distance from the edge of the board, half your pad could be drilled off.
- Use silk screens to indicate the orientation of your connector. I found it somewhat difficult to determine how my connectors are oriented because I left this feature out. Especially when I tried using the connector another way.
I still think it was a cool idea, but when I began separating the parts and putting it together I realized it may have been an over engineered product. It would’ve been easier to leave it flat and use angled headers to make the connection.
