Here is the first report, quite new facts for many, I guess, whilst routine for old CAD foxes. Key: be aware of humidity on inside of a PCB. Don't think this is a simple matter, far from. You can even cause damage to a PCB when you think ' let's increase the temperature ' , 'let's double the time' , or other home made countermeasures. I send it to Steve for best way of distribution. If there is another and better, give advice. Ingte ______________________________________________________________________ This email has been scanned by the Symantec Email Security.cloud service.
