MFG.com used to do some PCB assembly, etc. I had thought about signing up with them a couple of lifetimes ago, but, found the cost too much for my small company. *sales alert* My current company is in the middle of launching our beta services...we'

Key to Rosin Fluxes [from SUPERIOR FLUX & MFG. CO.] Type R (Rosin): Non-activated rosin flux for soldering copper. Residues are non-corrosive and non-conductive. Type RMA (Rosin Mildly Activated): Mildly activated rosin flux that contains no chlori

Yea, I always liked to program the way it physically sits in the feeder then rotate as needed in placement. Make sure rotation in feeder is 0 as well or you'll really get confused. Some machine mfg's recommend otherwise but it never made sense to m

Check into Bartector. Used this solution for 15 years at a previous employer. As long as your parts are labeled correctly (correct part number matching the mfg part number) then Bartector will have the operator scan the feeder to the part label. I

Dreamsniper, The optimum contact (dwell) time in the wave should be 2 seconds. Contact band width is a function of conveyor speed. For an example, 5cm of contact band width at 150cm/min. conveyor speed will give you 2 seconds of contact time and 2cm

| A user of one of our components exceeded the floor life of some plastic BGA components. They did do a pre-bake prior to SMT reflow but only 72 hrs at 40C and not the recommended 12 hours at 125C. I've recommended accoustic microscopy to look for po

IPC-7525 "Stencil Design Guidelines" is a good reference document to have. Here are notes from a Tessera, (a major mBGA mfg.), study- "Application Note Solder Stencil Requirement for mBGA" The stencil aperture is to be square, equal in size to the l

For manual X-ray systems: Kv power to start off with. Depending on what type of components you have to X-ray, you may be ok w/ just a 90Kv system, for example. Its not all about Kv though. With most systems you can adjust to quantity of X-rays you ar

If I understand your question, niether deals with it well. Intuitive did add an approved mfg for us which should now be a normal release in the next version, previously they only used approved suppliers which is rediculous. They are trying to support

The biggest thing you will not get is the vision system like this. The 7722 has flying vision for most components and an upward looking vision camera for large components and BGA's. The older Quads had the Quad Align system which is laser vision.
