The assembly process involves activity before you get to reflow. Reflowing is the easy part. Putting paste down and placing parts in wet paste is the terrifying part. Benchtop reflow ovens can be a real handy tool for small production but with the g

Checking the vacuum at all stations is a good place to start. A vacuum guage with a piece of hose attached to a CP nozzle is a very handy tool to have. If you notice less vacuum at any one of the stations, you can start by looking @ the spool valves

I�m sure the 10MPF is not a correct nozzle to use. I don�t have manuals handy so I can�t answer as to the correct nozzle. We use a HSP 4792 to place all of our passive parts so I have never given this much thought. But the machine will not try to pla

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

Does anyone have a suggestion on where to get a relatively inexpensive CMM for measuring my SMT accuracy? Even an XY table with a digital position display would be pretty handy to have. I use mostly Panasonic equipment at my current company, and I

Have a problem with Omniflo 5 (-97 vintage) pin chain conveyor. Occasionally the conveyor stops for a second or two, then makes a slight jerk, then stops again, makes a jerk etc. Then suddenly the problem goes away only to return next day (we switch

Consider this: The inner balls will be at a lower temperture than the outer balls in reflow, so if you cannot inpsect them then that may be where your problem lies. Are you reworking with a specialist machine that is directing the right amount of h

Yes, that's a great idea.. It'd be kind of like a "Yahoo! Groups" type page or blog site where it's possible to post pictures. That would really come in handy especially in a technical forum such as this where there are many situations that're easi

To do a profile at most companies, if you don't have a scrap board handy, you'll use the already-soldered board that's already been through ONE reflow cycle. You spend time attaching T/C's with the aluminum tape - after all, the prep-work is half th
