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

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

The IPC-610 class II spec is very reasonable. If they expect class 3 then make them pay for it....IMO

BGA Specifications for IPC Class

Electronics Forum | Wed Feb 02 21:56:11 EST 2005 | davef

Based on X-ray imaging, IPC-7095 standard specifies three categories for void size for BGA solder joints. These categories are based on the percentage of joint cross sectional area occupied by the voided area. Class III Small: Void area is LT 9% Cla

The small investemnt of purchasing the IPC-610 manual will pay for itself very quickly. A brief description of the two classes in a few words would be the following: Class II - a well built product with reasonable expectations for both the manufactur

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

So you are saying that building to class III is going to prevent failures? I disagree. Class III is trying to hit target condition in every aspect of the production of the circuit board. That my friend does not ensure failures from happening. I see
