It's hard to say something is "better" than something else. How is the Essemtec a better machine? Is it faster & more accurate for less money? Is it easier to maintain yourself? Does it have a greater install base and more service personnel per

Just to check and see if I'm using the right formula in my "cost per component placement" calculation is correct or not. Any input would be much appreciated. Total cost of the machine : A Depreciates over 5 years Actual/best UPH obtained 11000 cph

Has anyone developed a custom nozzle for these guys? http://www.osram.convergy.de/upload/documents/2005/03/03/14/47/LA_LO_LS_LY_E63B.pdf I've found that there is a deposit of epoxy at the base of the lens that can sometimes cause the LED to lodge in

I agree with Russ, a standard nozzle picking up directly on top of the dome. Do not go around (or over the dome) and try and hold the part from the base. Have you tried using a nozzle around 1.0-1.5mm in diameter and hold it from the tip of the dom

Hi John, What type of machines are you using? (for all you vendor-bashing badmouths out there: this is not an invitation to start advertising you personal favourites!) There may be people out there that have done this trick before on exactly the s

Can you not track placement accuracy/feeder performance/print performance just via the AOI in near real time? Once you get a feel for it you can usually tell where the fails stem from, and at most you are only usually around 10 minutes out depending

Stick with what you know, Panasonic make perfectly good machines that are in installs all around the world and last for ever. I believe the I-Pulse is a derivitive of the Yamaha/Assembleon platform & as such should be adequate. (I'm sure Base will

Rob, I don't have the time to do the research and prove my points. What I know is from 20+ years studying the competition. Any Fuji saleman would tell you that based on the original post the AIM platform is the better choice. Bigger board, more fe

We do both our ovens once a week. If something looks out of tolerance (we've developed acceptable tolderances based on many recorded profiles over time and oven mfg. specs.) we wait a couple hours and try again. The recorded data over time is very

Peter: Based on our company's experience with removing a variety of different coatings, including parylene, the BGA's can be removed. We would use a chemical etch followed by a neutralizing process. We would then reflow the devices and pry them off
