| May 19, 2020 at 17:01 | comment | added | The Photon | I've never had trouble with tenting both sides of a 0.2 mm via in a 1.6-mm-thick board. After plating there's not much volume left in that via to trap gasses. But for a larger via diameter I'd avoid it. | |
| May 19, 2020 at 16:44 | comment | added | Kyle B | Not sure where I learned or heard that. But I didn't make it up myself ;) But unlike alotta stuff we "hear about", this seems plausible and believable so I just go with it. Doesn't hurt to do it ;) so why not? | |
