Frequently, I need to do some SMT prototyping. Partly because some components are only available in an SMT enclosure (like the MCP4725, a nice small 12 bits DAC), partly because it needs to be small and sometimes it is Saturday 5 past 5 and the only type of a critical part available is SMT. Two weeks ago I saw on SMD shop a SMT prototyping board.
It features pads in 0.05″x0.05″ square pattern and every fourth pad is connected to the groundplane on the bottomside.
Looks quit nice, with the only drawback a price tag of 8.22€ for 100 X 80 mm board. (yes I am a skeap skate dutchie). Nowadays, you can order 10 pieces of 50 mm x 50 mm PCB for around €10 in China. So, I figured, why not design your own?
Below you see the result. the first figure is the top layer
The pads are laid out in a 0.05″ pattern an do have a size of 0.042″ by 0.042″. Every fourth pad there is a hole to the bottom layer. The holes are non-plated-through. If you want to connect them to ground just stick a small wire in and solder it at both ends.
And here is the bottom layer, which is usually used for ground layer.
Have fun! If you would like to receive the gerber files, let me now!
Update : you can download the Gerber files for the SMT prototyping board HERE !
