My company is very insistant on making our actual production times match the predicted. Perfectly reasonable.... However, the problem is that one operator can beat the predicted rate and another can blow it away 10-fold. I know the problem is tha

It sounds like your depaneling method is good. The only thing left to look at is to see if the depaneler is hitting the part somehow from the cutter or the bottom plates. I've seen time and time again where an operator has a part in contact with th

"As a great thinker/Philosopher like myself once said a few years ago:" Who was this great person that hated SMTnet years ago? MoonMan, you have to realize that when you boast silly things such as high CPH and new metals that no has ever seen, that

Hi, I agree, and normally we would not act like this to a real person, but this guy is a joke, and it was funny to read the replies to it, and reply. Guru is never going to be part of this forum, because he's just some weird guy who's too arrogant

I have read some threads about poor wetting on palladium-silver (Pd-Ag) coated components. I followed the suggestions, but I am still having a problem. The part is an 0603 chip type (Vishay varistor). The Process: solder paste is lead-free Alpha Met

Hi, One thing, getting back to the original topic, is you might want to panelize these boards as much as possible, as you don't have too many components, but you have some good volume. So the machine changeover time is going to be an issue. Althoug

Hi Efren, Did some simple math... - 100k units/month - 24 days/month - 16 hrs/day - 75% efficiency (ballpark questimate) You'll be looking at a line that does a bit more 50kCmp/hr with an IC/TH placer that does 3.5kCmp/hr (assuming 10 IC's /TH conn

When not practical to drill hole into pcb to profile here is what I do and seems to be just fine. place thermo into area underneath BGA and let her rip, you will not be in the ball/solder joint, but the temp difference as long as you are in the arra

With the UP2000 that has vacuum board hold down, the Grid Loc hoses defeat the vacuum in order for them to exit the work table. Big boards require more girds, thus more hoses. Set-up between large and small boards takes time to remove or add the gr
