You can still get support. I was in that deal before Tyco decided they didn't need Multitronics field engineers playing with Quads. Anyway, most of the original Quad personnel are stil running service. Based by region, in the West or Central US, c

Dye Penetrant Inspection of solder joint

We form a barrier to contain the dye, but regardless it is messy. Actually, we no longer use dye, per say. We use the stuff machinists use for staining metal. Look here for hints: * http://www.ivf.se/Elektronik/dye_penetrant/edefault.htm * http:

Flux residue on connector pins

Hi Chen, Based on your posted message, the following ideas are for your consideration: "brown residue" The water soluble solder paste you are using could be a water soluble rosin solder paste formulation. Perhaps the solder paste may not be proper

Looking for small Dishwasher type cleaning

To address the last sentence of the recent posting, Austin American Technology does have experience with board cleaners as described. More recently AAT developed a cleaning system simliar to your description called the AquaBatch. The AquaBatch was

'Blue solder' residues

Electronics Forum | Thu Oct 28 11:41:21 EDT 2004 | Steve Stach

Hello Loz, Blue residues on circuit boards can be caused by copper corrosion, component body deterioration, marking permanently, and adhesive break down. In this case, a more subtle mechanism appears to be possible. This is a no clean application

CSP No clean residue

The Jury is still out on no-clean reliability in the long term as no-clean didn't gain wide spread acceptance until the early 1990's. Also, in today's disposable society, few products are expected to last 15-20 years. Experience has shown that if y

Ionic Contamination Acceptance Criteria

The "Rose" test is a process control tool because it is cheap and easy to use. It has it's problems; but, it is generally agreed to be the best tool available for this purpose. All others are much more expensive and time consuming to run every day.

Cleaning film build-up in a Stainless wash system....

Electronics Forum | Mon Jan 31 13:38:17 EST 2005 | mrclean

This build up is likely related to the defoamer. Defoamers are typically based on waxes and/or high molecular weight Hydrocarbons. As defoamers only need to work on the exposed fluid surface, not a lot of defoamer is needed (unless you are using

how clean is clean?

Dear SM Rookies, Another acceptable test method is visual inspection. IPC-A-610 details what to look for with different contaminants, providing magnified pictures of the possible visual residues. With an existing cleaning process, magnification

System is too slow, Will memory/speed increase do job?

XP needs at least 256Mb of RAM, preferably 512. I think 1Gb would be overkill, especially with a 133 memory speed. It sounds like a dual boot configuration...if you don't need W98 on the machine, why don't you just dump it and get a clean install of
