Danny, with the Heller 1800 series oven, what is the standard oven profile for lead free. I am having some proble profiling boards with BGA. I am getting alot of voids. If you have a profile for a Heller 1800 nine zone, could you please send me a

What is the (initial position) ratio of pulse counts to home encoder pulse (relative to the home sensor). It should be 50% +/- 15% Run this test several times in between a warm up. I bet your numbers are all over the place. I bet you have a loos

I have always encountered problems when using Kester (everything from bad solder to solder balls). I have profiled the boards to the extreme thinking it was my reflow recipie, but with no luck. I ended up going to AIM and I have never had a problem s

Indium Pb paste has always been great but the flux tends to implode on the BGA's (despite many different profile strategies). The Indium Pb-Free is horrible...horrible, and have been kicked out of my lead-free eval. PS-I went to Moonman/Guru link a

Hi, I am experiencing cracked solder joints on ceramic resonators after the ultrasonic plastic weld process. PCB assy is placed into plastic housing and then housing halves are ultrasonic welded. Not a soldering problem. I know this component is

Check flux penetration and type of flux. How much is solid contents. The solder filling is better under Nitrogen. Check the time (speed) of the nozzle whether is correct. Usually For SAC305 the temperature of bath is 320C/degrees, but only for sel

Hi, We have been running Soltec reflow and wave, and are very happy with them. The software on the Soltec oven is great, but a bit stupid on the wave. However they are both great units, and after about 38,000 PCB's they are still totally clean with

I agree with Dave 100%, ATC will expose the board and components weaknesses and potential design problems and/or the need for conformal coating. The life span can only be predicted and/or extended by well-documented field failure analyses history and
