Why worry and why is he worried?  This is all cosmetic.

If this is a problem you may suggest the elimination of the white legend.

Subject: [TN] White legend turning yellow


Hello Technetters,

One of our customer faced this unique problem with our boards

The white legend (silkscreen) on the boards is changing to light yellow
color after baking
When he complained, we checked the boards in stock
and we too observed the same phenomenon

No other job processed on that day exhibited this behavior
The baking parameters were normal as usual

Any comments or views will be greatly appreciated

cheers

Madhu
