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

Subject: Re: [TN] IPC/EIA-J-STD 002 Steam Ageing



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
