Hi Jim - MIL-STD-202, method 208 is nearly identical to the ANSIJ-STD-002
document with only a couple of differences so using the 002 or the 202/208
should not be an issue. The reason the 202/208 method has not be completely
rolled into the 002 standard is the current inclusion of the soldering iron
solderability test method in 202/208. The 002 committee is still
debating/evaluating/reviewing issues associated with that particular
testing method and as with most specifications there are many view points
to be understood before a consensus will be  reached. There are equal
numbers of folks are using the 002  and the 202 specifications
successfully, so review the 202/208 exceptions to understand how using 002
as a standalone impacts your solderability needs. And  you must be
telepathic! There are current efforts to unite the MIL-STD-883/750/JEDEC
B102 solderability specification series with the ANSIJ-STD-002
specification. The JEDEC/EIA/IPC specification organizations are working
together to set up a series of meetings to work toward the goal of having
one specification for the electronics industry.  Contact me if you would
like more information.

Subject:  [TN] Solderability requirements per ANSI/J-STD-002




Our company is an aerospace supplier, we have traditionally imposed
MIL-STD-202, Method 208 for solderability of component leads. The latest
revision of 208, H rev, points to using ANSI/J-STD-002. Is anyone in the
industry using the J-STD-002 document exclusively without reference to
MIL-STD-202?
Since our older documentation specifies MIL-STD-202 we would like to
change the documentation to specify the J-STD-002 and the new methods
for testing described in J-STD-002.
How are other industry companies addressing this change from MIL-STDs to
Industry Standards for solderability. It would appear that MIL-STD-202
will be replaced by the industry standard, so why not use it
exclusively?
