Getting people to stop sounds like a good idea, but once they get running after a lengthy set-up, you can sort of understand why they don't want to stop when they quickly run out of paste after emptying a partially filled tube. Beyond the paste qual

Ideally we want to mix the same lot numbers in a repackaged tube. Once again, these are partial tubes that have been thrown away. If the ratio is right to begin with the only change would be due to air exposure. Semco makes a TC seal which, if we

I have over 10 years experience in aerospace materials, part of which was involved with vacuum casting inert propellant formulations. These propellants are in the range of 80 - 90% solids loaded with viscosities of 15 kP. I'm not sure where I could

We have been looking into some sort of higher level inspection system as well. But we have been fairly well convinced that X-Ray is far better than AOI. X-Ray is not only good for BGA's, it is also good for any solder related problems. AOI can onl

why not just run some of your money through a wave solder machine and burn it up...same thing as buying AOI machines. Absolutely no ROI...not yet, anyway.

What are people using for AOI systems and how are you using them We are on the market for 2 systems post reflow capable of inspecting solder joints at 010 sized components we have 2 old systems at the moment inspecting for presence and polarity p

We like our AOI from Cyber Optics but only use it for process prove out. I would rather have a solder paste inspection system in line. The cost of AOI is killer. A new process is to embed a UV signature between the components pads and when a componen

Ours works good with the inspection of components, but looking at solder joints has a lot to be desired. There is lots of new names in the AOI business. Like any other equipment, do your homework. Ours has had their share of problems, but I think it

Good Morning Bryan, We are using Mirtec MV-3 AOI's with 4 megapixle cameras. We use them for 100% post reflow. We are checking, presence, polarity, value, solder, bridging,component height for BGA, QFN etc... and 1st piece validation for machine set

Genny, Xray systems ( or at least what I have seen ) are a manual based system. That is, you put the board on the machine and look at certain locations that you want to inspect. What we have in mind is an automated system that will catch obvious, no
