Board #5 - Proffieboard v2.2 Orange, KR Sabers
Symptom(s):
- Loud squeal. No USB data connection.
Inspection:
-
One whole side of CPU is a big ol’ bridge.
-
RN4 has been chopped in half, and the missing side took the pads with it.
-
Not hopeful on this one. Assuming CPU damaged from the many shorts.
Fix:
Started with clean up of CPU mega-bridge. Fluxed the whole thing and reflowed with hot air. Actually looks promising now!
After:
- Now to RN4. Removed remaining 1/2, pads still good there.
The plan is to scrape away some trace mask and some on the opposing side VIA.
Overblob solder, and use the force…
Well, that came out looking pretty good as well.
However, still no data WHILE ON TESTBED POGO PINS.
But, it shows up on Port when just board to USB. Hmmm. desolder/clean board pads.
Upload test config.
All looks good in Serial monitor. Back to testbed…
It’s alive! All working well.
Remember, The Force will be with you…always!
