PCB Technical Specs
The following specifications define the requirements for single sided and double sided pcb's to be submitted to our production department. These requirements can be easily checked using your pcb program and the various tools included with the program.
Track Sizes
Careful consideration of the current passing through the track needs to be made prior to determining the track size.
Minimum Track Width: 10 mil
Minimum Track Clearance: 10 mil
Pad Sizes
Pad sizes are determined by the size of the lead or device to be inserted in the hole, the larger the device leg the larger the pad, this will secure the device and prevent damage to the board or trackes if the device is moved while fixed to the board.
Minimum Pad Size: Hole Size + 20 mil
Minimum Pad Clearance: 10 mil
Minimum Pad Size for VIA: 40 mil with a Hole Size of 20 mil
Recommended Pad Size for Resistor/Capacitor: 62 mil with a Hole Size of 36 mil
