I know that on Philips Topaz equipment you can define the XY locations of the individual local fids relative to the mount-center of the component that they apply to. So if they are not symmetrical w.r.t. to the QFP's center there's no harm done. You

All, We had a power cut the today. Machine times out on Actuators and Paste Dispenser hence it will not Initialise fully. I have traced back each related card but all seem to check out fine. Next step is PSU (looks awkward to access) Any ideas fe

"Many manufacturers charge to register their equipment prior to selling parts or providing service." True, but in most cases those fees might actually net something you can't get somewhere else, like some technical expertise. C'mon, it's not like th

Bottom line is, If you have to pay a fee to buy spare parts then the company is not worth doing business with. They obviously have no intention of becoming a partner only someone to take your money at every opportunity. Lets keep this a technical f

The need to Pre-Bake depends on multiple variables: 1. Packaging from the vendor (dry packs, vacuum sealed, etc...) 2. Storage at your facility (temp, humidity, etc...) 3. Moisture absortion rate of Laminate (FR406BC is one of the highest) Other rea

SWAG - Was your experiment on the board with the large ground plane? The board we are seeing issues with also has a large ground plane (approx 50% of PCB), and 90% of the delamination occurs in that area. The delamination is about the size of a sil

We ended up switching PCB suppliers and PCB material altogether. We built 400+ units with the new material and got zero delamination. It's still unclear what the real solution is as we introduced two changes at once. This new supplier is going to

I hate to drag this one out again but we are done with this. We tried an oven profile on the bare panels that was quite different from our original. This profile was recommended by the mfg. of the laminate. We experienced random delamination. Som

We have Mydata's as well. What I would like to do is have printouts in a binder. But I'm not sure the easiest way to do this and no one has time. This way you could have an offical shape for a given part number. Some parts might need two like those

Hi Mika, Thanks for your reply. We've managed to narrow down the fault to the control board (long rectangle one in front of the camera). It turned out to be a logic IC that had blown MM74HCT244N (U17 I think). A circuit diagram would be useful beca
