Hi, It sounds like your a little new at profiling, and can be difficult to do well. We purchased a KIC profiler that has software that will take your profile data and tell you the best oven temperature settings and conveyer speed to use. You need

It is possible. If the talcum powder mixes with the chain lubricant, it could gum everything up. Back a few years ago when I was running an SMT Quattro Peak, I was having an issue with the conveyor chain drive motor going into overload. We had to pul

I have some engine over load problems in the central reel, has it been identified that the external team misuses talcum powder for rubbers and many times we find talcum powder in the shafts, however will it be enough to cause the engine over load? Do

Thanks for the feedback, I've been having some problems with the motor overload in the conveyor and central reel whenever there is cleaning by the external company. After analyzing I always find talcum powder and lubricant (it looks like cement) on t

Hi Bartel , 1.1 Profile Solution to Cold Soldering Cause for Cold soldering The peak temp of reflow is too low. The preheating temp is too high and it takes too long Solution Lower the preheating temp and increase the peak temp in the reflow zone

The lowest peak temp. I've had the pleasure of working with is 240°C +/- 5°C. I can't imagine a manufacturer going much below that and still saying it's lead-free compatible. It would be interesting to know just how much TAL plays into the affect

Hi, I am facing high fall out of microphone low sensitivity issues. This microphone is soldering thru SMT soldering with low peak temperature profile which peak at 232 DegC to 240 DegC and have skipped X-Ray inspection but still seeing fall out espec

Yes, I am currently using Viromet 347 at the moment for my SMT lines. 100-150, 35 sec 150-207, 40 sec 207-above, 80 sec peak temp: 225 deg C. It is compatible to SAC paste in term of solderability and wettability. But in term of mechanical property (
