I am curious to know anyone has used Samtec SEMA Solder Charge connector (SEARAY Seriese. I have done manufacturer's recommended solder paste and good reflow profile still the solder is leaching to the lead instead of becoming a solder connection. T

REL alloys from Aim solders maybe worth looking into for this application. May I ask what your profile on reflow is like please, especially peak

For the ovens you run the profiler and you compare graphs. For the AOI you should run these golden boards(boards that you keep for AOI test - might have intentionally implemented defects) once in a while and make sure you are getting the same results

The profile I have shared is for SMQ92J leaded solder paste

Ours says it needs to cool down, but if I put in into cooldown, I can load the next recipe right away. I don't actually have to wait until it cools.

I just tried that Friday and only the first 2 and last 2 zones will turn on. Are you using DOS software?

Mine is DOS so that might be the difference. No one can seem to figure it out. DO you know anyone that works on these ovens? I am feeling I am going to have to call in someone.

I do have access to a DOS HELLER 1500. And we can just change RECIPEs without cooling down first. What is the message on the screen when you just try to change it from one RECIPE to another?

Nothing only the first 2 sets of heaters come on and the last 2 sets the middle 4 just sits there and does nothing

So the first two zones come on and the last two come on, and the middle zones start dropping temperature? What happens if you let that go?
