First, butget. Second, flexibilities. If you have tight butget, you better choose used SMT equipment instead of the new one. It will save you hundreds of thousand dollar. Second, if you change model more frequently, you do not have many to choose. Fu

We've also seen it where a component has had a long soak at a high temp (last one was 220C for 1.5 minutes)without exceeding PBT. The long soak was due to the oven only having 3 heated zones. On the last occasion there was some concern over the lea

Strange that - whenever we take on a new customer & agree to work together in a spirit of partnership they invariably try returning all of their old failures, often with our labels hastily re-stuck over them. We often change the copper ever so sli

"Note: nothing changed to the process, the problem come out of sudden." Did this happen with a batch of boards you'd been running a while, or was it a new batch (lot/date code)of boards? I'd be inclined to suggest that the environment that your my

Exactly. Also consider how customers are begining to dabble in LF and want to use the same FABS for concurrent builds. The don't want to add or modify any PCB artwork and pay for NRE changes. And they don't want to keep two part numbers for the sa

Does it do nozzle changes at a different speed than the programs? It's been a while since I worked on these beasts. I"m wondering if it can handle slow speeds but at full bore it can't handle it. Maybe try one part with everything set to slow speed

Thanks Rob, I have samples and production quantities that we are running on leaded assemblies now. I guess my next question would be, if you are already building lead-free assemblies, how are you processing the electrolity and tantalum caps? The o

All, I have been asked to review how we come up with costing of products. Basically, can anyone share how they do this i.e. If the machine can run 60 boards per hour what is a fair allowance for reel changes etc. I am guessing 15% . Any help/ad

Hi Ken, Thank for your advice We suppose that with home position all is OK and ratio is in interval 40-60%.Y axis offset is not constant 5mm or 10mm but change ratio with working time and may be more than 10mm We think that problem is with Yservo mo
