  • Programming header selection

    Hi,

    I'm designing one PCB which will produce in 3000 pcs quantity and more. The PCB contains STM32 microcontroller. There are 8 pins of the microcontroller which should connect to the programmer and this connection will happen 1 to maximum 4 times of every PCB forever. what's your idea to implement this connection? If I want to use one 8 positions pin header for every board and if the pin header was at least 0.5$, for 3000 pcs it will cost about 1500$ or more for us. As I checked some of microcontroller boards which produce in high quantity, they put some pads for programming and no header! How they then connect to these pads without any problem in manufacturing? I attached some photos of these boards.

    Thank you,

    Maybe test points + needles are what you are looking for? Google for "bed of nails pcb". Let me know.

      The topic is a bit old, but I've used those before:

      The cables are a bit expensive, but if you don't need many cables it's quite convenient.
