1) PCB quote needs Your Gerber layers – Altium PCB Fabrication output Files, Multi-layer printed circuit board for example, we need the layers as follows:
| GTO | Top over layer for silkscreen |
| GTP | Top paste layer |
| GTS | Top Solder layer |
| GTL | Top Layer Copper layer |
| G1 – N | Mid-Layer Copper layer |
| GBL | Bottom Layer Copper layer |
| GBS | Bottom Solder layer |
| GBP | Bottom paste layer |
| GBO | Bottom over layer for silkscreen |
| GKO | Keep Out Layer |
| GM1-N | Mechanical layer |
PCB quote Note: Silkscreen —– Verification of the polarity of diodes, caps, and ICs.
2) PCB quote needs Drill Files — Altium PCB Fabrication output NC Drill Files as follows:
| *.DRL | Binary format drill file. For a multi-layer PCB that incorporates blind and/or buried vias, a separate drill file for each layer pair is created, with a unique file extension |
| *.DRR | Drill report – detailing the tool assignments, hole sizes, hole count and tool travel |
| *.TXT | ASCII format drill file. Again, for a multi-layer PCB that incorporates blind and/or buried vias, a separate drill file for each layer pair is created, with a unique file extension |
PCB quote Note: “*” is your PCB design name or printed circuit board (PCB) name.
