Yes it is possible to detect lifted leads with top view camera's. The camera's must be coupled with software that utilizes algorithm programs. MVP - Machine Vision Products out of Carlsbad, California uses algorithms in their software. Most AOI co

Hi , Using the Agilis feeders 3/4 months now. We are low volume so they haven't worked hard , but we have had no real problems. They seem to work well with both paper and plastic tapes.As for components we use them on 0603, 0805 ,SOT ,mini-melf & t

I called a new customer today and told him that one of his parts on the proto boards (a capacitor with a polarity 'tit') was too long for the pads and the pads were small causing the end opposite of the "tit" to lift up. I suggested that the product

Yes l know this problem keeps cropping up on the forum but l've missed some of the follow-ups. Our problem is that the lifting only occurs on 3% of production so actually detecting an improvement is difficult. We're actually having to inspect 144 p

The Technical Services Group at Alpha Metals has spent a fair amount of time looking at wave soldered Pb-free connections. We too have observed fillet tearing, fillet lifting, and pad lifting. I have concluded that without major changes in the mate

Here's part of what I could read: "We evaluated the influence of Lift-off (Fillet-lifting) and the influence of thermal fatigue, in this case on combination between various terminal platings of electronic components and Pb-free solder, Sn-37Pb solde

There used to be a product simply called bean bags that you put on a pcb to keep components from lifting up during the wavesolder process. Any one know where I might find this product?

Most of our product are mixed technology. I don't consider thru-hole components as "pesky." Perhaps from a manufacturing point of view they are due to the extra handling and machine requirements. But from a reliability stand-point, thru-hole is mu

I have been using ICT for a number of years. It is still a viable resource for catching defects in the production process. AOI doesn't catch everything, such as bridging on QFN or J-lead devices (this will depend on the type of AOI and camera syste
