We are interested in doing some further studies on our cleaning process, particularly with respect to how well we can clean underneath low profile components. As an SMT subcontractor, we'd ideally like to qualify our chemistry/cleaning process to cer

Hello all, I am in the process of converting our facility to noclean processes. So far I am experiencing troubles with soldering to gold finishes. The finish is an H.P. type1. The solder joints appear dull and grainy. They seem to be very strong

| Does anyone have thoughts on BGA rework. We now use the OK BGA 3000 and now am considering an Infrared machine. Any thoughts? | I've used Pace, Conceptronic and, now, SRT machines. Bottom side IR is OK. Better thermal balance is achieved with hot

Hello everyone, I am currently running a gold plated SMT board and am experiencing tiny solder balls between the pads and the masking between the 20 mil pitch devices. I'm looking at these boards with a 60x microscope. IPC-610 say's any visible solde

The KIC Prophet system does indeed deliver as promised. The Slim-KIC (datalogger portion) works well and is worth the price of admission by itself. The Prophet portion of the system (resident in the oven) works great and decreases the requirement for

I am currently running several SMT lines that are placing components onto dispensed adhesive (Heraeus PD 944). My problem is that we have always had an issue with a resin type liquid �condensing� on the inside of our oven chimney and then running bac

I don't think that anyone is saying we want to barr reps at all. I think the issue is that people get irritated when when certain reps work their sales shpeels into a forum response that does not warrant it.That's all. I value this site tremendously

It does sound like your leads are to long, speeding it up will reduce volume on lead and most will wick up the joint but when slow excess solder is left as long leads will have little flux left to aid drainage when it leaves the wave, thus giving a s
