Hi, Hemendra Recently, We have carried out lead Free Soldering On our 4+1 Panasonic Reflow machine. Results were fine , but its Not Recommended for long Run. but the machine which you have is 5 zone machine and additional 2 cooling zone too. Check

Its a vitronics, with a little proper maintenance it'll go on forever! If it's a 610, you should have 6heating en 1 cooling zone btw.

Lead Free in 5 zones is tough sledding. Start with your manufacturers solder reflow profile and calculate your belt speed by looking at the recommended heating time for the solder paste vs. the length of your heated zones. Set your belt speed so tha

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

Hi Ronald, We have both, 2x calrod on our leaded delta and calrod/convection on our leadfree, both are IR in 3th zone. Indeed, the forced convection is way more efficient, we can run it at 100deg C, where we would need 300deg C for the calrod for t

Thanks for the response. I am using mainly two brands of ovens. One is Heller and the other is a chinese brand called Fulongwin (copy of Vitronics). I see the problem in both, more severe in the Fulongwin. Both are 8 zones and a few 9 zone Hellers. I

I am seeing a problem of flux droping on the PCBA during reflow. This is a pb free process and I am using KOKI pb free paste with 8 zone (and some 9 zone) reflow ovens. Line throughput is about 10,000 boards/24 hours. I suspect that the exhaust is no
