You need to profile to the paste. And if a part can't take the temperatures, then you have to have something done about the parts. At one time most components had peak temperature information back when we didn't really need it becuase profiles were

Smartasp, Certain software packages used with Reflow Profilers have a tab where individual TC's can be set to a different spec. This will allow you to monitor package temps while still monitoring the solder paste specifications. You can define each

hi all! i have a 5 zone BTU (V70) have it set up at 120, 150, 180, 190, 230 and 22 IPM. but i having 1 here 1 there 0402 tomstone, need advise how to set up the best profile to avoid tomstone. i'm using INDIUM 6.3 W.S lead paste. thank you.

Check out this paper: http://www.xs4all.nl/~tersted/PDF_files/Plexus/tombstoning.pdf You can also search the SMTnet archives for more information. If you're tombstones are random as you describe, likely the problem is not with the profile; but som

Has anyone attempted to, or successfully used a custom made (DIY) protective thermal enclosure for the Super M.O.L.E. gold profiler? We recently purchased a Bravo oven that came with everything for the ECD profiling system... except for the thermal

I have also seen on Heller ovens (even new ones EXL series) cross profile temperature differences over their spec of +/- 3 deg C, sometimes up to 7-10 deg C, 200-230mm from fixed rail. This can cause funny issues , profiling can cover this up and not

I am doing the case study of the component chip 0201 tombstoning problem. The significant causes was the reflow profiling preheat slope or ramp up rate. I really can't differential between preheat slope and ramp up rate. Could anyone here show me the

one of my customers with a BTU VIP 70 has the following settings, 100 / 175 / 210 / 250 / 265 with conveyor speed of 18 ins per minute. They get a peak temp of 240~245C and time above liquidus of 220 C is @ 55 secs. Built in thermocouples should give

We are not having any real issues. I am just first setting up a lead free profile, and was looking for a starting place. So far it's going well. Can you tell me more about why your paste would be better and I'll pass that on to the decision makers?
