ICSP Header

KeithSloan

I want to create a small PCB that will act as an ICSP header for a PC16F877A i.e. The Board will use a stand off connector which plugs into the original circuit board with the PIC. How do I get the appropriate bottom layer for the small header board

    I'm not sure I understand the question, but a through-hole header will have

    pads on both sides of the board. If this is a commercially made board, then

    you can have traces on both sides of the board. If this is homebrew, and

    the header is mounted on the bottom side, then you need traces on the top

    side. HTH

    Also, I am tired of Eagle packing my 6 long traces 8 mils apart when there

    is 1/2 inch of room all around---they could easily have 40 mil separation.

    But you can't simply set it for 40 mil, since in many areas (such as at

    the chip pins) 40 will would never work & the routing fails.  There should

    be an option to optimize spacing with different preferences (in some case

    you do want them packed tight together)

    First, your emotional state is not our concern.

     

    Second, what does this have to do with ICSP headers?  I don't know whether

    you can't read the topic or deliberately tried to hijack someone else's

    thread, but either way neither you nor your post belong here.
