NettetNormally, when calculating the PCB hole diameter, the aspect ratio between the diameter of the hole and the thickness of the board is considered. If the thickness is 1.60mm, the hole size should be about 0.40. This means that the aspect ratio, in this case, is 1:4. Reducing the thickness of your PCB means that this ratio should also be reduced. 7. NettetResults: All patients were found to develop full-thickness MH within 1–4 months after the last anti-VEGF injection, even in the absence of pre-existing vitreomacular interface abnormalities in some cases. The median number of injections before the MH formation was 3. Conclusion: MH formation may represent an adverse effect of anti-VEGF ...

So, for 1/8″ material, a 1/4″ diameter is often a good bolt choice. For 1/4″ thick material, perhaps a 3/8″ or 1/2″ bolt. This guideline falls apart for very thin materials, and for really thick stuff.
