Also look at IPC 7095 which is all abotu BGA processes including rework. the profile will be 100% based on your board - how many layers, how many are ground & signal, how many of those are the BGA connected to directly or indirectly, the component we

I don't use the machines you have; I'm running a Siemens line. Regarding fiducials, this data should be provided by the design engineers through some kind of mechanical drawings. I usually get this with the CAD data. I don't know if there is a standa

We have an older line scan camera on our MY series machine.(The one that uses the X wagon trigger/encoder to turn on the line scan)When I go into the service program and turn the line scan camera to "camera action on" the LED's will only stay lit for

Hey guys, I was wondering if there was a standard set of tests used to evaluate flux chemistries for wave soldering. For several years, we've been spraying Alpha 871-25A flux from Alpha Metals onto our printed circuit boards with relatively good suc

Hello All- I am in need of some low cost solutions for conveyors. SMEMA Conpatible about 3" (1meter) in length. Single stage is fine....I will even consider good used one...Free would be even better!!!. I have checked the archives and came up empty.

Actually, Fuji machine corp. was founded on chip cutting machines.(Metal cutting machines) Fuji incorporated what they knew from this industry in the design of their circuit board assembly machines. I come from a long line of mechanical design engin

We agree with John. It's possible to clean under 1.27 and 1 mm BGA. These devices have a reasonable stand-off that allows cleaning of water soluable flux residues with modern cleaners. So, if you have process problems with low-res fluxes, what mak

We use them on our DEK printers. They have worked out very well. The only thing we had to do was make a push down bar so we could push all the pins down and lock them. This makes setting up the blocks much easier; board is fixtured, pins released

I am using a board w/fiducial, still problem. Now is Vision Align is same as Teach vision. My teach pull-down menu doesn't show Teach vision, it shows Vision Align, Vision Inspect and etc. It is a new m/c for us. I can use any help. Thanks

Now that is creative! I going to talk to my machinist. I need a bar of aluminum machined to accept 24 pigs (ass up of course). Then I need a "squeezing" mechanism to apply a proportional pressure to the pigs abdomen to make the "ass gel" support t
