Questions are: * What is the current plating on the connector that is over the "plating of the leads is Nickel (99.9% purity)"? * What are the temperatures and durations at those temperatures that you read on these connector leads? * What solder allo

Hi Dave, The peak temp on the leads is 216-218 Deg C and duration above MP (179 degC) is 55-60 sec. Alloy(solder paste) used 62 Sn,36 Pb 2Ag (Alpha WS 609 Ty 3 Water eash) This is a SMT connector wth Gulwing leads Gold plating on the PCB is 2-5 micr

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

Now the big question is how do they get the lead in the pencil? Don't answer that. Anyway now that we all know that there is no lead in the lead pencil (which we already knew) I still feel it is not good practice to use a lead (Graphite-clay) pencil

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

Thank you friends for your discussion Regarding the reason behind using Solid disk or donut fiducials.Still I am understanding clearly the reson behind using Solid disk or donut fiducial shape. In all the above discussions we had we did not discuss a
