If you have upward looking cameras, can you assign the part to the smallest field of vision camera to get the dot out of the search area? Or, I've used patterns on GSM but have not had the need to use them on our Advantis yet. It appears you can ma

Hi, There is lots of threads on this, so I would search these, and then do some reading. Then once you have some brands in mind, call the suppliers of this equipment and get some demos to learn about how each machine works. There is lots of differen

I have only used the Quad 4C, We bought it used and ran good right out of the box without the need for repairs. It uses quadaline and does not work very well on IC's. We place 30K 1206 parts a week with a 4 % dump to bin. I have to tolerance set to 3

Yes, I have tested some boards, and found that most QFPs which near the via will have the higher temperature. One of my customer requirement is to have the temp less than 200 deg C for top side. We were using the hi temp wire to solder the QFP's for

Well, what I have takes data directly from the Protel 99SE placement file, so in the present form it is a bit specific. This file is simple ASCII text, but the layout of columns will be different on other CAD systems. What I have has a number of sh

Oh, I should have been more specific on microscopes. I have a Bausch & Lomb StereoZoom 5 and an old Olympus. They both work pretty well. I think the Olympus has a little better depth of field, but the B&L has better contrast. (Maybe the Olympus j

"I just need better reasons than it [...] increases defect probability." If that's not enough, you have bigger problems. Have you seen any rework/repair that was generated by this handling gem? Does your company profess to build to IPC specificati

Thanks davef! We found some SOIC & QFP with all leads having toe down problem. The heel fillet unable extend to the mid point outside bend. Do you have solutions for the problem? I have a question: How about the normal gull wing lead which is flat &

Hello, we do have very good results with a 'hot air' repair station, and poor results with a 'IR' repair station, but i have to say that the 'IR' station wasn't designed for leadfree use. Make sure you have a good underside heater, adjustable and

I use a Liberty Bandit brand hot air rework station and have placed 676 ball BGA's with very few problems. All of our products are now RoHs. They have good product support and easy to use directions. I think this unit runs about 15,000 or so. Good lu
