You're correct it's a goofy question. Voltage is going to be circuit dependent, since the ball will be connected to the board. There's some ball dimensions in the fine SMTnet Archives ... they're about four times the diameter of your wires. If tha

Not much activity here in the past few days. Just wondering if you all have been egg nogging it too much in preparation for jolly ol' St. Nick. Or could it be that some have taken to smoking the mistletoe? I hope DaveF. has recovered OK from his re

There's a bunch of suppliers [Fabmaster, Unicam, GC-Place, CircuitCam] listed in the fine SMTnet Archives. You have to be a bit partial to CircuitCam, it's a ground-up product designed for our work by someone from the business, not some cobjob on a

I do not think so. The 54 mm has a large field of view, so when it looks at small parts the image is blurry. What you want to try is using the other camera (camera 2) it has a 38mm field of view. Camera 2 is considered a narrow field of view, the cam

All, Thanks for your quick response. However, my primary concern is not the question of solderability advantages of nitrogen versus air. With all things (zone temps, track speeds, flow rates, etc.) being equal, what would be the profile differences o

I used to switch my N2 on and off for different products and I had performed profiles on the products with and without the N2 on and there was not a difference in the profiles. So you should not have to adjust your profiles. I think everyone else c

I am student at Northern Illinois University and am doing a senior design project on applying castellated solder pads (pads on the side of the substrate) to a hybrid circuit. I have had difficulty finding related articles. I found this website and

OK, now let me ask the really dopey question ... so if the irregularity of the HASL surface is punching holes in the thermal gasket and causing shorts to the heat sink, why are you putting solder on that surface? I wonder how the thermal conductivit

Is it possible to find the Cpk value for attribute data? We are running into problems due to unspecified LSL/USL values. How can we find the Cpk values without specific LSL/USL? We would also like to get some reference books on this subject so any
