These are old material call outs, but even the new ones will not
guarantee what you are asking.

Subject: [TN] 20 solder cycles?

Fellow netters. Here is a question that was posed to me this afternoon.
Any help would be greatly appreciated.
Dan S.


This circuit board is to be repairable, and as part of this requirement,
certain parts (surface mount resistors, surface and through hole
capacitors, and wires) need to be capable of 20 solder cycles.  

The previous design was manufactured to the following IPC standards:  
    IPC-6013
    IPC-FC-241
    IPC-FC-232.

My question is, do these standards specify resolderability, or are there
other standards that would specify resolderability?
