I don't have a plasma cleaner either. It will help a lot. Actually I don't clean at all. Our wirebond pads are far enough away so the flux residue does not get on the wirebond pads. That's what we think anyway. I am sure we have some degree of c

We socket no parts prior to the wave. This practice is an artifact of the days when we�d solder PTH socketed parts from the heat of the wave being conducted through the socket leads to the leads of the component. Sockets??? Thaint sockets no more.

Regarding your customer suditor, it would have been nice if you said something like ... Routinely, our testing shall be less than 1.56 microgram/cm^2 NaCl equivalent ionic or ionizable flux residue, according to TM-650, Method 2.3.35 'Detection And

Currently in our facility we store used and discarded flux residues from the wave solder machines in 50 gallon drums. These drums are picked up and disposed of by an outside contractor. During a recent audit we were cited for not having the drums pr

Never heard of flux residues forming a lense. The first thing that comes mind when thinking about your 'fog test' is: Ionic Contamination While this seems pretty far afield from your interest in optical effects, I'll continue briefly. A reverse

I've never heard of steaming a board either. You said that steaming cleans it better after the wash process. What is the steaming process cleaning that the washer isn't, flux residue, solder balls, or what? Also, try and identify the main difference

Adding a Chemistry will reduce density of solution to get under the devices more effectively. You can clean your OA flux residues well enough with just hot water and hot DI water rinse. Top batch cleaners: http://www.speedlinetech.com/electrovert/aqu

davef: I am a colleague of Sara at Foresite and we came to the conclusion that the solder balls were entrapped based on the minimal amount of information from the original question and the fact that the x-ray showed the balls and it wasn't mentioned

Hi Jay, I'm guessing that you have either: a) heated length of 64 inches b) a zone temp of 230C and not a surface temp of this magnitude c) Burnt pizza's 8 mins at 220C for a perfect non frozen pizza, however I find that the thermocouples keep fal
