LONG TERM Your plans to buy a vaccuum bag resealer and a batch drying oven sound good as you say, but you�re correct. They will not help with this current situation. SHORT TERM If your connections are clean, free of pits and holes with a smooth,

Jeezuz... Darby is right. High Tech Squeegee blades are a crock of BS.Don't belive the hype. Its a big scam to rake in your dough. We use .008" thick spring steel stock from McMaster. There is only one thing:The blades must be dried off thoroughly af

Agilent has a great article on determining whether automated optical inspection (AOI) or automated x-ray inspection (AXI) is right for you. It's a PDF file that can found here: http://www.ate.agilent.com/EMT/LIBRARY/X-RAY/DOCS/59883661en.pdf To sum

Since yer talkin� $$$$, non-quantitative measure do not apply. I understand someone told you to do payback. But, we don�t use payback for multiyear projects. Regardless, the analysis is similar. For each machine, set-up a multiyear spreadsheet li
