You don't say anything about the appearance of the solder joints themselves. That would go a long ways towards identifying and possibly resolving your issues. Heating and cooling could affect performance if you have a/some cracked or otherwise loose

Did You verify operation of the oscillaators(resonaters) by heating and cooling and looking at the waveforms and frequencies when doing so. We have problems when they are not packed correcttly from vendors , and sometimes they can get crackes in them

IPC a 610 has this info. An 0402 however mat require more solder than what IPC states (basically evidence of wetted fillet for class2). more paste = more flux = better wetting. Why don't you tell us what pad sizes and layout you have and stencil t

Hi Russ, Thanks for your input. Currently, our stencil is at 5 mil thickness and the paste height from 5.5 to 6.5mil. I have increase the paste height to 7 to 7.5 mil and great improve....... I just need some data to present to my management and tel

Another nuisance with the new SlimKIC - even for Sn-Pb paste we run a little hotter peak temperatures - you can't run another one in succession because the "internal" temperature is too high as well. Typically, I have to put the unit underneath a fa

Our MOLE was the same way. Setting it on the floor was the best way to cool it down. I'm not sure you're ever going to do much better than a factory shielding box unless you just build a bigger one and put the whole thing in it...profiler and facto

I sewed a sock out of a Nomex/Kevlar blend fabric because we had the same problem with our profiler. It works great. After one run through the reflow oven, the internal temp rises by about 5 degrees C. It used to go up by about 20-25 C. I can pic

Hi, I spoke to Kic about this at the Apex show in Feb. They told me it was OK to use the Orange Monkey Fur box for lead free. I even asked about my old side kic and they said it was OK also. I guess it depends on how high your temps are. I agree

Found the aramid fabric (Kevlar) on the website you suggested. Which thickness Aramid-and-Fiberglass Sheeting should I get, do I need to buy a strip as well to protect up to 600F? I was going to use PTFE-Coated Fiberglass Thread as it is rated up to

Hi netellink, I am not familiar with suzuki machines, but it usually works that way. There is a sign on the nozzle(it could be dots or lines...)and a recognition file for it. So you have to check: - if the sign the machine is looking for is damaged
