Just curious... if I find some parts that are only available in discrete die form, is the following procedure reasonable to actually use them on a small production budget?
-- Take a die and epoxy it down to your Teflon or FR-4 PCB
-- With a manual wire bonder, bond out the wires to regular old PCB pads
-- "Glob top" them by dispensing a dollop of epoxy on top of the mess
Have anyone done this? Will a wire bonder connect to ...gold plated PCBs? Solder plated? Others?
Manual wire bonders are cheap enough that it seems this could be pretty viable for small production runs... for the epoxy dispensing, I would imagine there's some machine similar to a solder paste dispenser that could be used, but even carefully dispensing from a syringe seems viable.
This approch seems to be the manual version of how something like a digital wristwatch is built, as far as I can tell.
