Typical work pieces
The following table details tool sizes available in the Mechatronics PCB mill. Your PCB Design minimum clearances and hole sizes should be matched to suit this tooling.
|Drill||0.60||23.62||Transistors –TO-92 / small diodes – 1n4148 etc…|
|Drill||0.80||31.5||1/4 Watt resistors etc.|
|Drill||1.00||39.37||Pins and diodes – 1N4004 etc.|
|Drill||3.175||125||Holes for screws / standoffs etc…|
|Pointed mill||0.20||8||Minimum clearance between tracks and pads|
|0.25||10||Preferred minimum clearance|
|Contour router||2.03||80||Board outline / cut-out. Can also be used for holes|
Producing a board
Follow the flowchart on how to get a PCB produced (PDF, 40.3 KB).
To get a PCB produced, email the gerber and drill files to firstname.lastname@example.org. You will be informed by email when your board is complete.
Instructions are based on DipTrace. Please take note of design restraints.

Exporting Gerber and drill files
Once the board design is complete, Gerber and drill files will need to be created and sent to email@example.com.
Single sided boards will require 3 files:
- Tracks (Gerber).
- Board Outline (Gerber).
- Holes (Drill).
2 sided boards will also require a second tracks Gerber file. <
