Unfortunately, we have found an assembly orientation mistake of U1504 and U1505 for the last build of 20pcs you have done few weeks ago
We have tried to operate but all 20pcs failed at the functional testing, and when checked we have noticed that on the bottom side the 2 components were placed wrongly, where on the top the same 2 components (we have 4 in the Adelaide BOM) are placed ok.
Can you please investigate how did this happen? And how did it pass AOI?
Please send us the root cause investigation and corrective actions so it will not happen again for next build.
Btw, the first 20pcs where ok, this orientation problem happened only on the 2nd batch!
Looking forward for your fast reply.
