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

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

Ok. F.Y.I How I could make this work: We use Almit V14, and SMT ovens. You can say that we don�t do our maintenance as good as we should. Our Smt Quattro peaks are equipped with process gas cleaning (wich works quite good actually) I ripped out the

Alas we as Americans are destined to be innovators and consumers. However, we do not consume what we innovate. We wait for the Euro and Japanese conglomerates to take our ideas, mass produce them, and then sell them back to us. They are fueled by

I'm not on the production floor on a daily basis like the other guys here but here's my 2 cents: With a Ni/Au plating the inter-metallic that needs to be formed is Ni/Sn. Ni/Sn inter-metallic requires higher peak assembly temperature and a longer dwe

Dear All I have a question for the reflow machine. I'm using Vitronics(Mr933+)reflow. The peak temperature of the (Chip, LED, SOT) component higher than (QFP,LGA) about 4 degree when i measured proflie. All of them on the same board . I don't know w

I'm trying to help one of our remote sites solve a problem with a warped PBGA. The corners are lifted, creating columnar joints and the central balls are sometimes shorting. I've verified that it's not popcorning and I've got samples going to the l

Yeah, that's what I'm doing now. I have it now peaking around 235, with about 70 sec. above 220C. (220C is the reflow temp, according to manufacturer. I've always used 217C for Pb free) Wish me luck. Thanks!
