Hi Steve - You can use ANSIJ-STD-003 to evaluate any surface finish for solderability but you may have to adjust the test method(s) to fit you application. As with many specifications the new alternative finishes (Pd, Im.Au/ENi, Ag) are not specifically addressed (technology moves faster than documentation) but the IPC Solderability task groups are working on making the specification more robust and relevant in for these finishes. I don't know of any specification that addresses Immersion Au/ E. Nickel at this time. Contact me directly if you have more questions.

Gold Does the IPC specify the requirements for a surface finish of E. Nickel/ I. Gold when used for creating a solderable surface? If not what documents are to be used for specifying this finish. The attributes I am interested in are: - thickness - composition/purity - hardness - roughness (if applicable) - adhesion or test method for adhesion - anything else I may have forgotten that is important. **** IBM MD Product Quality Engineer **** **** OEM Quality Engineer **** **** Interenterprise Address: USIB6CEF **** **** Internet Address: [log in to unmask] **** *************************************************************************** * TechNet mail list is provided as a service by IPC using SmartList v3.05 * *************************************************************************** * To subscribe/unsubscribe send a message <to: [log in to unmask]> * * with <subject: subscribe/unsubscribe> and no text in the body. * *************************************************************************** * If you are having a problem with the IPC TechNet forum please contact * * Dmitriy Sklyar at 847-509-9700 ext. 311 or email at [log in to unmask] * *************************************************************************** *************************************************************************** * TechNet mail list is provided as a service by IPC using SmartList v3.05 * *************************************************************************** * To subscribe/unsubscribe send a message <to: [log in to unmask]> * * with <subject: subscribe/unsubscribe> and no text in the body. * *************************************************************************** * If you are having a problem with the IPC TechNet forum please contact * * Dmitriy Sklyar at 847-509-9700 ext. 311 or email at [log in to unmask] * ***************************************************************************
