Hey Reese what is your Mis rate? Do you have any boards that are passed that have actual defects?

That's an interesting point about ionizers. They say the primary means of transmission is through droplets suspended in air. I wonder if ionizers kill the virus and what the turn over rate is for a room of a given size.

Dear All, I'm encountering a problem on mounting Intel E7501 and P64H2 FC-BGA chips. After the SMT process, these two BGAs were defected. Both had power-to-ground short circuits on the die package itself, and also the die resin had cracking tracks

Extra cooling is better (Alpha recommends -3 to -7 degC/sec) for cosmetics. Less chance of s o called 'cooling lines' that look similar to 'cold' tin-lead joints. (Seems a bit steep to me - I worry about the risk of cracking ceramic caps.) Might be

"The only real problem we're seeing is some suppliers trying to use bismuth. That's a big no-no in a SnPb process and we won't accept those parts." Yes and no. Since the SnPbBi tertiary alloy melts at 96 degC, any product rated for storage above tha

Agreed. However, this is for a research paper that my boss may turn into a presentation designed to be given to accountant types. As such, I'm looking for an average hypothetical example. I know that conditions may vary with circumstances, but I'v

Hi DaveyF, Thanks You see, you proved my point, with piles of more information than I gave. Based on Application rather than design and manufacturing specifications, a lower IPC class can out perform another. So our starting Poster must look at t

We are currently experiencing a high rate of false calls on our 0402 chips. Resistors for the most part. Has anybody out there found a setting where this false calls are minimized? We are using top red light, pattern inspection,color inspection ( wh

agree, if you have fine pitch components the placement rate will be much less of what you see in the catalogues as they quote 0805 components placemen rate. I have one year log for one of our machine which is quoted to be 6400 cps and for one year a
