What does "maintain it really good" entail? For reference, this is our maintenance procedure for the FX-D: - At the end of an 8hr shift, the solder paste path is purged start-to-finish using Nordson's ValvePurge. The machine's then powered down and

So, a couple of things... First, you're asking about water washing a part, but, note that the manufacturer says to NOT ultrasonically clean their microphones. Those can be two different cleaning types...assembly shops using water wash may not be us

I have a question about solder masking via's in a BGA pattern, and want to see if I'm thinking correctly about this. This problem is kind of along the same line as Carol's problem earlier. I think it's a bad idea to leave the via's free from solder

Whatever the cleaning process is or will be, after cleaning make sure you check on X-Ray for any solder balls/debris in microphones. This is a friendly reminder to check, unless you want to receive customer complaints. Been there, seen that - we went

| I know this topic has probably been talked about before...But I ran into a small situation where Solder Balls were appearing in large quantities on the PCB....the Problem has been isolated and taken care of, my question is, what are some good metho

Doesn't really look like no-clean to me...typically, no-clean encapsulates the solder joint after reflow, trapping any organics. This looks like plain-old water soluble flux, that cooked a bit too much in reflow. As you noted, it cleaned up with

We have been having problems with solder paste balls around fine pitch ICs and have decided that cleaning the boards in an ultra sonic cleaner may reomove these solder balls. However we are worried that the ultrasonic cleaning process may damage the

Hello Mark, I wish it were that simple so I could direct you to a particular manufacturer and stencil cleaner model. Unfortunately, there are several issues complicating the process of cleaning all these applications in one machine. First and fore

Hi Ramon, The obvious answer you might expect to here from me is that you could probably reduce your misprint problem if you had a good stencil cleaning process. Please see my response to the question by MarkT on �Cleaning Materials� because it i

Hi Dale, I have copies of the articles of which Mike references. If you need copies for support, contact me at: bill@smartsonic.com. Rinsing should be done by ultrasonics also. Spray in atmosphere systems will not penetrate into the same tight ar
