Before placing your order:
Check that:
- All connections in your schematic are present
- Inappropriate connections are not made including short-circuits.
- Review the Edit Nets Dialog.
- Job | Analyze was used to resolve any errors.
- View each layer separately and all together.
- Silk screen overlap with pads is not present.
- Job | Settings - check all settings.
- Job | Parts List - check all fields.
- All footprints have entries in Job | Parts List.
- Unambiguous device orientation is shown on silk screen per markings on the device. Diode cathodes are on the pad next to the silk screen dot or line. DIP IC pin 1 is near the silk screen semi-circle. Quad IC pin 1 is near the silk screen beveled corner.
- Uniform orientation is made for ICs and other polarized devices to reduce assembly errors.
- Component packages don't overlap.
- Copper footprints exceed component leads to allow inspection of solder joint.
- If you plan to make a custom enclosure at eMachineShop, first export your layout to DXF to verify alignment.
- Assembly by Pad2Pad is per "standard" Capabilities.
- Traces width is at least .008".
- Hole diameter is at least .015".
- Silk screen line width is at least .008" wide.
- Edge gaps between copper and board edge are at least .020" for V-scoring or .060" for tab-routing or .010" for Individual routing.
- Pads are unmasked at those made with Polygon or Circle tool.
- Four layer boards - select View | layers... Set checkmark next to "1st inner" and "2nd inner" to open a four-layer view and see the inner layers. Use the Window menu to select the original view or just close the layers dialog.
No checklist is 100% complete and must not be taken as a substitute for careful work.
Once you have thoroughly checked your design, you are ready for ordering.
Upon receiving your boards it is strongly recommended to:
- Test or at least visually inspect the bare boards (four layer boards must be electrically tested).
- Assemble and test one board before assembling all boards.
- Test a board alone prior to placing the board into a system.
