IPC Class II and Class III reliability

MA/NY DDave, I'll take your money. I'm betting on the Class II, whatever that is, because: * Solder is the same. * Board is the same from a fabrication and probably materials standpoint. * Components are the same. * Processing is the same. ... but

Hi This is an excellent question or research project. I would call the IPC and find out if anyone has already done this work. My guess is that Class III should be slightly better, yet considering the application difference where Class III is used

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

IPC Class II and Class III reliability

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

How do you prove IPC-A-610 compliance to a federal agency?

Electronics Forum | Fri Jul 09 20:54:58 EDT 2010 | bandjwet

There is no such thing as "IPCA610 compliance". The correct way of looking at this that the boards were inspected to IPC Class I, II or III Revision XX (current Rev is "E") and met all of the criteria. From a commercial standpoint it would greatly

solder paste(SnPbAg)

Sn62Pb36Ag2 has a higher liquidus point of 189C as compared to Sn63Pb37 at 183C. You may need to slightly adjust your oven profiles to use it compared to SnPb. We have had good solder-ability and reliability with it in our IPC Class II products. A

Whether there's a fillet or not depends on the component type. Most have a fillet but some, such as QFN's, don't necessarily have one. Have a look at IPC-610D Workmanship Standards to understand when you should expect one and when you shouldn't. T
