Just exploring options to improve wetting. It turns out our facilities dept is looking at an N2 generator to supply dry boxes. Thought it might be a good idea to assess whether we should expand the project to include reflow.

Used this paste on ENIG boards W/O N2 and had very good results. (0402's,BGA's,16mil FP) Never had the need to use N2 with this paste on our products. Running with N2 shouldn't hurt anything. The wetting properties should get even better than they ar

my oven has a built in profiler, it works fairly well, but it can not predict changes. my main concern was about the time right before reflow. i know that's where the flux is activated and i was worried that i may be spending too much time at the tem

You can keep only the 5th zone as the reflow zone. And lower the first two zones to keep a good ramping rate. Meanwhile,please note the ting temperature in software or control panel is not the exact temperature in your PCB, you'd better get a KIC or

Take a look at this. Remember, these are only guidlines and can not replace any paste specs. As Real Chunks said, a profiler will be of HUGE help. We use this to determine what our top side temps are and to see if we have any problems with heat sen

I am trying to optimize my reflow profile. i have a 5 zone oven. lead-free: for the 1st 3 zones, i am good, at about 150-200 deg for 150 seconds. during the 4th zone, i am at a temp of 200-220 for 50 seconds. during the 5th zone, i am at 220-245 f

Ideal situation is get a technical rep from the solder paste supplier. They know their paste better, and should be able to work out a profile based on their paste and your oven. Again, a technical rep, not the sales guy.

Do you have a Slim-Kic? You can run a profile and then do predictions from there. Very useful tool.

thanks, looks like an interesting product. any idea of the cost? they don't list it on their site. not sure if i can afford it yet.
