The specs on the laser for an LPKF say plated vias down to 200 um diameter.

The specs on the laser for an LPKF say plated vias down to 200 um diameter.
- K0balt 5y agoSeems like that might be just small enough to make this work?
- PennRobotics 5y agoI imagine a microvia cut by laser would work quite nicely on three of those pins. The fourth pin, Vcap, would be frustrating, because using two vias to place a capacitor on the opposite side of the IC is labor-intensive, and using two vias to place a capacitor beside the IC is a bit of an unnecessarily long signal path for a filtering component. I'd rather gouge a hole and solder a capacitor directly onto the IC between Vcc and Vcap, but "gouge a blind hole in the dielectric and solder an 01005 capacitor to the IC" is not a commercially viable answer either. Maybe pray your design doesn't need Vcap or that this can be tied to GND?
