Greg, The best advice that I can give you is a PBGA will respond just like any other surface mount package. There may be a 5 degree delta between a PBGA 356 and a QFP208 but the two respond very similarly in the convection reflow environment. CBGAs

Does anyone know of any good profile prediction software for free, trial or on the market that is not coupled with hardware. We want to specify the environment, paste, board and oven etc variables and have the software suggest the best cavern temper

I have the same Heller 1500 and am about to start evaluating paste. Would you be so kind as to provide your oven set points to give me a baseline to start with? I think this would save myself and others a lot of time and effort ;-) Thanks James S

Hi Scott, My Heller is a bog standard Heller 1500 with an edge guide. There is nothing special about it. I would of course love to have a 7 zone oven, but...I have to use what is here at this time. My only concern with a 5 zone oven is the change i

Sarry, Word on the street is that your profile will have to be hotter, maybe up to 20C hotter, I have trialled lead free. The sales guy said, "Right, lets reprofile your oven ! I said, "No, lets try it as it is.....! The results were fine, as the

As we have vitronics oven(SMR610A) made in dec,1997,which has 5 heating zones and 2 cooling zones. For Lead free soldering what should be our baseline for low/medium boards.we have gathered profiles from various paste manufacturers,however we don't k

Jay - I read your report and was interested to see that you ran your evaluation on a Heller 1500 5 zone. We have been hearing for some time that a larger machine (7 zone min)with higher temp heaters and fan motors would be required. Is yours a "hi t

There are many profilers(physical devices) on the market. Most of them have software that makes predictions based on information about the paste, oven model...., but I wouldn't trust the predictor as on your boards you will have different parameters

woow, slow down hot rod, hey davef, you are alright by me, good to see some one out there that has hands on experience rather than a theory nut.... any how, you need a top of the line profiler, super gold mole, or Kic.... these truly are the best and

Today, I have just finished evaluating Kester's EM907 (SAC305)lead free solder paste and found that for our applications it performs as expected. End result that I am encouraged with the results that we got. The equipment that I used: An SMT2020 to
