We have recently started building assemblies containing 0402 components (argggg!!). Were using the TM8FC magazines and are seeing alot of miss-picks on the 0402 components. When the feeder advances the part, the part can; jump out of the tape, or tur

Again, the verdict is mixed here as well, but from the seminars, white papers, etc. the consensus seems to be that Pb BGA's are not compatible in a Pb-Free RoHS Process...but... Pb-Free SAC BGA's are compatible in a Sn-Pb process as long as your pro

Haha, I have so many of these stories... where to start? My favourite was a few years back, we had a new mechanical engineer fresh out of university. As a part of his new role, he was purchasing tools & equipment for the maintenance workshop. After

Okay, now we can get rolling here. Here is a couple of things about selective wave that Ihave found very helpful 1. Make sure that no parts on back side are in excess of .15". if they are we skip; out in SMT and handsolder if labor costs justify.

Does replacing the BGA fix the problem? To be a little more blunt, is the BGA or is it the tech says it's the BGA. Beleive none of what you hear and only half of what you see. What kind of BGA is it? If it is one of those BGA's with a built in heats

If your frame size is 730mm x 730mm then you can't move it left or right. If it smaller than that then the frame adapter will give you more leeway. I am not too sure by what you mean by "If I had a 6" board, and a stencil with cut-outs for both side

Yes, I agree with guest. Lay it all out with masking tape on the floor. Include the width of feeders sticking out. Confirm the position of power, air, network and smema connections. You may even want to use cardboard layed out on to the floor. You ha

With the UP2000 that has vacuum board hold down, the Grid Loc hoses defeat the vacuum in order for them to exit the work table. Big boards require more girds, thus more hoses. Set-up between large and small boards takes time to remove or add the gr

A couple things on the Grid-Lok system. They now offer a top-side edge clamping system. The edge clamping system works very well for warped, twisted boards etc.. Using this system in the auto mode also allows the pins to contour to the geography of
