I'm looking for comparison data on MTBF for solder joints meeting IPC Class II vs Class III.

Sirs, what would be a good way to judge the reliability/robustness of a stencil printer or chip shooter? Does any equipment supplier specify detailed maintenance schedules? Is there a source of machine failure data (MTBF, etc.)? I not

Hi I don't think I will enter this too much except for one of your questions. YES multiple reflows affect reliability. Heck most everything affects reliability. Aggressive Heat cycles or Heat always affects the final MTBF reliability number. The

MTBF is hard to nail down raw data based on whether or not it is classified as IPC CII or CIII alone. Given that most failures are environmentally based, you might be able to get this data for CII and CIII in similar environmental testing situations

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

How often do you have to replace the blower motors? I will ask the oven manufacturers what the average MTBF is for their blowers. We have numerous BTU's and I don't think any of them have required replacement before 8 years (single shift). Once they

I am looking for a quickly obtainable procedure on the repair of SMT boards. I am particularly interested in discrete components, such as capacitors and resistors. I need to know the importance of pre-heating the board and components. What is a good

Dear Sir, I do not want to mix in this "subjective" discussion but as an employee of Assembl�on (buider of FCM II, FCM multiflex 50, 75, 100) I can provide you with MTTR, MTBF, placement data (0201), software, and other (also customer) data on our e
