Armando, Make sure chip wave is pumping evenly across. These TD machines require a lot of maintenance (deep cleaning)to ensure all the holes on nozzle are open... My two cents, George

Thanks ! I will try your recommendations, about the flux and the preheaters, yes they seems to be ok I will bring down de conveyor speed because it looks like if it is to fast is set to 3.6ft thanks again!

Check that you are getting an even spray pattern from the fluxer.Check that the chip wave nozzle is clean and if possible feed the PCB in to the wavesolder unit at 90 � or 180�.

Hi, In our factory, we are using the solder paste from Multcore, LF300, but this solder paste will stop being manufacturing. So, I need to choose another solder paste to use in smt lines. I would like to know which criteria I should use to choose an

Thanks everybody for the answers. I already chose 3 differents solder paste brands. And, how many boards it's necessary to perform these evaluation tests to have a reliable result? 20, 50, 100 boards?? Thanks.

Phil Zarrow wrote a useful paper that could help in evaluating paste. Here read it ... Evaluating Solder Paste � Not An Option Contributed by Phil Zarrow of ITM an Independent SMT consulting firm With soldering being the dominant source of assembly

Hi, There are quite a few suppliers so you could have a lot of work on your hands trying them all. Do a bit of research finding out what paste all the big guns use? they spend a fortune doing evaluations etc But you should get at least 3 different

While both of those products do make it easier to profile the wave, a standard reflow oven profiler, with some long thermocouples, are all you really need. You can even use the standard Thermocouples and send the profiler through the oven on a traili

Hi, I was just hired on and put in charge of the wave machines. One lead and one no lead (lead free). My company currently does not have a wave profiler. He wants me to jury rig the re-flow profiler to work on the wave. I really think we need one ma
