Data sheet allows of 250 DegC peak temperature and we are using below 240 DegC but still seeing high fal out. Manufacturer diagnose as BE charges loss due to heat. Hence, looking for anything extra could be done to minimize this defect. There is no w

Grant has a good idea, we started that way also. We made a tank out of stainless steel with copper tube coils about 18" off the bottom. Circulate cold water through the tubes to condense the vapor to keep the loss down. We used electric burners under

The numerous traits of an electronic assembly comprise high volume assembly, BGA, AOI and 3 dimensional solder paste inspection. The value incorporated features of these assembly services comprise low loss, blended technology assembly, many layer, du

I am currently working on a custom IC where we plan on using Cu pillars at 80um pitch. I'm am trying to narrow down a packaging solution. My requirements are as follows: 40um Line Width/Space Capability (or finer) 4 layers low loss at mm-wave

Nichrome, manganin, phosphor bronze etc are easy to solder ... the hard part is removing the corrosion * Manganin: 86% copper, 12% manganese, 2% nickel. Often, it's used in making cryogenic measurements, due to its low heat loss. * Select a flux for

>But since we are a low volume high mix operation I need to account for almost every part used.99.5% (financial) We then also report the machine reject information on an inventory adjustment sheet. This seems to cover all the bases.

Low DCV on batteries should not cause issue with MINT download, but will cause loss of MINT files (and necessitate reload) upon power down... Please contact me for additional assistance. http://www.dekhead.com
