What are your standard hole sizes? We have a wide range of drill bits so we can drill any size hole from 4mil (0.1mm) and up. Holes that are .250" (6.35mm) and larger will actually be routed with the CNC router. Unlike some PCB shops, we don't restrict you to a few 'standard...
Standard Sizes of PCB Standoffs PCB standoffs are manufactured in a range of standard sizes described by the stud diameter and length. Common imperial and metric sizes include: Imperial Standoffs Stud DiameterCommon Lengths #4-401/4″, 3/8″, 1/2″, 3/4″, 1″ ...
The standard 2.54mm hole pitch makes it easy to align components, while the variety of sizes caters to diverse circuit designs. Whether you're working on a small 2x8cm breadboard or a larger 5x7cm project, this kit has you covered. The double-sided design allows for efficient use of space...
3.2mm mounting holes, 4mm from center of hole to edge of PCB minimum 6mm keepout around mounting hole to leave room for standoffs minimum 1.7mm edge keepout for case clearance Other notes for case designers we see PCB widths vary up to +0.4mm, and recommend you design for up to +0.4...
