Hi Edgar, we had a similar thread in summer this year on this forum. Not in particular focusing on every detail of this topic but more of a philosphical view of some aspects of your intentions. Positive: It�always good doing new things. Combination o

Wolfgang: Sounds like gluteus maximus protection time. 1 "Maximum suitable temperature for the solder joint should be half the liquidous temperature" is a good rule of thumb. Where it came from, I don�t know. One place I�ve seen it repeated is: H

So far I'm into the investigation stage of the AOI project. The system I'm most interested in is the Intelligent Reasoning Systems, Inc. I'm after fast programming with minimal false calls. I'm not interested in X-ray. I saw the system at NEPCON

Charley, I dont know what you define as durable but the one thing that I know about the QP 242 made by Fuji is that its slow and a very clumsy machine. The QP 242 is what Fuji calls there modular concept machine. I dont know about you but when I hea

Horace: You weren't real specific about the set-up of the two machines. So what's the diff man?? Big dross generators are: 1 R Woodgate says that pump speed is the biggest driver to dross production 2 Chrys uses low dross cast bar: Alpha HiFlo 3

Temperature vs time is what soldering is all about. The faster you run your conveyor, the more heat will have to come from the pot for a given assembly. Example: You heat the board to 200F top side through the preheaters. Eutectic 63/37 melts at 361.

Hi all, Been thinking about this problem because it's costed us some errors before. For the same type of parts from different vendors, the polarity of parts in the taping may differ from vendor to vendor. (Actually, we find that parts from most ve

Guys, I am not really looking for an automatic system. I am looking for as automated a system as I can get for $30K or less. I would really prefer something under $10K. I just need a way to sample devices to see if the vendor is meeting my coplana

Obviously, clean enough :-) I don't think I've ever seen a specification, although some companies obviously have in-house ones. It would depend on the process used. For ex., if you used Parylene, where the coating is done in a vacuum chamber, you wou
