houkime | what is the particular reason for choosing ESDA6V1-5P6 for display connector esd instead of, say, SP7538P that we use on bob? | 14:07 |
houkime | SP7538P has 6v6 instead of 6v1 clamp but it fit WAAAY more nicely | 14:08 |
houkime | and is a bit less ridiculous from esd standponit since it allows for much shorter (literally nonexistent in the case of our display) traces | 14:09 |
houkime | if you look at how metacollin routed parts of display esd because ESDA6V1-5P6 geometry forced him to do so you might wander what will the actual esd voltage reduction be in case of esd event | 14:13 |
houkime | SP7538P are only slightly (~10%) more expensive (which is not really a TCO difference because of holes the other part require) | 14:28 |
houkime | besides, the UPPER board will be dense as hell so giving extra routing space for esd is not really affordable. | 14:30 |
houkime | *may note be really affordable | 14:30 |
houkime | *not | 14:31 |
houkime | remember that you don't want any other track or component be near the unprotected part of the track | 14:31 |
