PCB Manufacturing Policy on hole size / slots / internal cutouts

  • The given hole size would be the final hole size with +1 mil tolerance.

  • The given slot size would be the final slot size with +2 mil tolerance.

  • Unless otherwise stated, the 60 mil routing tool would be used for internal cutouts. This will result in right angle rounded turns centered on 30 mil radius
1 oz Advanced Process is available on request and cost is to be quoted on case by case basis. All the quoted cost on this website assumes standard process run. Advanced process requires minimum lead time of 2 weeks.  Minimum order requirement for advanced processing capability is 500 sq inches of PCB.

Custom Specified Material - The use of custom material (eg. Rogers/Arlon) can is negotiable for jobs with minimum run of 15,000 sq inches. Please contact our sales engineers for further details.

 Standard FR4 Specification -

Significant part of our PCB production uses Kingboard's  FR-4 . Please download the PDF Datasheet  for material properties details.
