PCB Stuffing
Stuffing the PCB will be done by installing all of the connectors and headers. Following that, all of the
resistors will be installed, starting from the lowest value and proceeding to the highest. Then, all of the
capacitors will be installed, using the same scheme. That will be followed by the inductors and
transformers, and then the diodes. When all of the passive parts are on the board, groups of integrated
circuits and transistors will be installed followed by simple tests to assure that circuits are active and
performing to specification. It is highly suggested that you print out both schematic sheets and use a
highlighter to mark each component as it is installed. This will assist you later on if you have parts left
over and wonder where they were supposed to go.
Connectors and Headers
[ ] Start construction by installing Power Jack J1. Hold this part toward the rear of the PCB so that is
projects out from beyond the edge of the board.
[ ] Install the 4 audio jacks at locations J5, J6, J8 and J9.
[ ] Install the 3 BNC jacks at locations J2, J3 and J4.
[ ] Install a 2-pin header at locations J7, J11, J12, J13 and J14. Supplied with the kit is a break-a-way
20-pin header to be used for the 2-pin and the 3-pin headers. Use sharp diagonal cutters or a hobby
razor saw to make the appropriate cuts.
[ ] Install a 3-pin header at J10.
[ ] Install the 20-pin IC socket at location U1. Make sure to get the orientation correct; match the
notch in the socket with that of the silkscreen overlay. Once it is soldered in, it cannot be removed
without destroying the printed circuit board.
