Vijay, Sounds like you're not spending enough time at liquidous plus 20*C. And you need to stay there for 5 to 10 seconds. I know, I know. We have used bucketsful of WS609 over the years. See, as you say, the melting point of your solder alloy

Good Day, We have been searching for ways to do this very thing. We have sent them out for cleaning in hot baths, ultrasonics, pressure wash, etc... The chains have come back cleaner than they left but not perfect. At one point, one of our engineers

We had one of these years ago. We had trouble with it recognizing fiducials consistently, but other than that it ran good. This assumes that the left head, which is mechanical centering, is working good. And I believe that the minimum component

Scott, We have 2 Amistar Placepro 5620's and 2 5720's. One with a TF-14. I've personally been working on these for the past 10 years or so. Have a pretty good grasp of the process, if placepro's are what you are using. Glad to see Amistar is

Temps are related to the components/PCBs being soldered. I am not aware of any Industry standard. If you are soldering flex circuits, .020" boards etc.. We use 500 deg tips a little thicker PCB/lead we go to 600, and so on. We never exceed 800 in a

Dave, I�m talking about the 75% vertical fill of solder IPC 6.3 criteria (B), and 6.3.1 Fig 6-5. I also referred to the annular ring of the Plated-Through-Hole, being coated with solder mask. Semantics, yes I did refer to the Plated-Through-Hole (Sup

Hi Sorry, even though I have seen a machine in action by a test engineering department years ago, and remember some advertisements since then, and maybe have seen one at a show, I don't remember the names of the companys. If I had to I could probab
