Hi frank, At first we did see some issue with moving the boards. We placed the AOI�s in as central location as we could. Basic we do first articles and sample QC�s from the less critical locations like paste inception and TH. And then run 100% QC o

A thorough analysis is in order because laser point-to-point soldering lacks the flexibility of the bottom sided miniwave systems. My experience showed that heating profiles could be grossly affected by color temperature and thermal mass. This can be

Unfortunately, we don't have that option under Utilities. Must be UP-2000 specific. I've set everything up correctly, multiple times...All the right dimensions, etc, taught fids, and it still tries to load the board in the wrong position. As far a

Juki KE-2050R (or any of their R-series machines). They have the ability to automatically learn pick positions on paper tape feeders and they can zoom in on pick locations (x2 or x4), so this will help when they release their nozzle for 01005 compon

On the non-wetted holes put a solder iron to them and see if they "bubble" if so, you have some outgassing in your PCB and they will need to be baked prior to assembly. If this is okay I would investigate the grnd layer that was mentioned. What is

After profiling with a scrap board of the product I'm profiling, I would immediately send the MOLE through with one thermocouple only, no board, to provide a standard that I could reproduce without depending on scrap boards. I used that setup before

when we run a pilot run it usually takes a lot of time because it needs to be properly adjusted so that on production time everything could be set up easily and run smoothly. on a no feeder situation, components for the next model should be already l

I would love to buy enough feeders, just for the common parts but unless I find somewhere cheap to buy them it can very expensive. We use our own internal part numbers with using smart feeding stations. Also we are going to try to leave all the comm

This sounds like exactly what I am going through here. If you come up with a nice solution please post it. One of the things I have done is make top and bottom programs similar as possible. No I didn't say all programs the same overall just each job

Steve, We're not so sure that we've had enough of your rant. You say "I think it is the only place that looked pre-SMT for issues that everyone else just assumes is SMT. Any complete solution to SMT changeover times will look at pre-SMT as much as
