Before beginning the development process, gather together the following information and equipment, including:
- Accurate schematic diagrams and a component locator of the board to be tested.
- Converted CAD data (
board
,board_xy
). - Material lists identifying the circuit components, pin number diagrams, and component values and tolerances where appropriate.
- Fixturing information (type, size, custom attributes).
- At least one known-good PC board (we recommend at least five known-good boards).
- A blank PC board, one not loaded with devices, to be used as an aid in determining pin 1 and 2 of analog devices and in fixture verification. (If you do not have an X-Y data file, you will need the blank board for digitizing.)
- Adequate pin cards.
- Power supplies.
- Any needed external instrumentation.
- Documentation on all custom and analog and functional devices on the PC board.
As the development progresses, additional information may be required. This additional information may include:
