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 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

The IPC-A-610 has the Acceptability requirements and the ANSI/J-STD-001 has the Requirements for soldering. Both deal with the requirements for the individual classes. Both of them are published by IPC and can be purchased in lots of places includ
