Hi Amol! Yes, the more appropriate term is "steam conditioning". Look in
the JSTD-002 appendices, there is a listing of the equipment producers
(Appendix E I think).

Re: [TN] IPC/EIA-J-STD 002 Steam Ageing
Thanks Denny. Specifically, I was looking for the names of equipment
manufacturers in the US who manufacture Steam Ageing chambers and the
solderability testing equipment (dip and look)
Thanks,
Amol

Amol,
You are going to get it from Dave Hillman, chairman of IPC 002!!! He
likes to refer to it as "steam conditioning" or "steam stressing". People
try to equate performanc in steam stressing to the aging of the component
in storage. Storage in Singapore is far different from storage in
Winnepeg.
Is there some part of this paragraph on equipment that is a problem?
3.3.1 Steam Conditioning Apparatus The steam conditioning chamber shall be
constructed of non-corrodible materials such as
borosilicate glass, quartz glass, stainless steel or PTFE. The specimen
holder shall be non-reactive to prevent galvanic corrosion. The
container should be insulated. The steam temperature at the conditioning
level shall be maintained per the requirements of Table 3-2.
Table 3-2 Steam Temperature Requirements
Altitude Average Local
Boiling Point °C
Steam Temperature
Limits °C
0-305 m 100 93 ± 3
305-610 m 99 92 ± 3
610-914 m 98 91 ± 3
914-1219 m 97 90 ± 3
1219-1524 m 96 89 ± 3
1524-1829 m 95 88 ± 3
A safe means to prevent excessive pressure and a means of maintaining
adequate water level shall be provided. Neither shall cause
the vapor to cool below the specified temperature. Condensate shall drip
freely back to the water. Care should be taken to minimize
contact between the condensate and the specimens.
Fin ally, do you have comment on either dip-and-look or wetting balance to
measure solderability?

Dear Technetters,
How are people in the industry complying with the category 3, test method
A, B
or C of this requirement for high reliability applications? the 002
standard
calls out for steam ageing and then solderability testing for components.
What
equipment is being used for steam ageing and solderability testing? I
would
appreciate any direction on this matter (on the forum or offline if
somebody so
desires)
Thanks,
Amol
