SMD_Prototype_PCB_Rev_B.zip

Design by: fmuntean

A prototype board for SMD components.


On the internet usually only find QFP or SOIC to DIP adapters where all pins are routed to the border headers. Everybody building circuits know that not all pins are going to be used and that decouplic capacitors are better to be put as closed to the IC as possible.


I designed this boards taking all that in consideration and more.


This prototype board has different areas for different chips.

  1. a QFP 32 to 64 0.8mm pitch area with pins wired up to at least one pad.

  2. a QFP 32 to 144 0.5mm pitch area with pins wired up to at least one pad.

  3. a SOIC 32 1.27mm pitch area with pins wired to the pads.

  4. one are for mounting a STM32 microcontroller board like the blue pill. but it can be also used for any small two line board or IC.

  5. multiple headers single line are mounted in different places on the board. They can be used for connectors or to mount any other dauther card on top of bellow.

  6. some of the traces can be cut to fit the schematic as needed.

  7. some of the traces are thinned already to help with applying more solder if they are used as ground. They are kept thin enough in order to allow for cutting if needed.

You will find that the vias are plated trough. This allows for soldering AWG30 wires and also will see how usefull they are during the step of testing the soldering of the chip.


This is a two layer board so you can solder a two line header (ex. 2x20 header) on the side of the PBC to provide more input/output lines.


Be imaginative this board can be cut up if needed and posibilities of cutomizing it to your needs are endless.
