Full Description

This standard defines the requirements for fully replacing undesirable surface finishes usingsolder dip. Requirements for qualifying and testing the refinished piece parts are also included.This standard covers the replacement of pure tin and Pb-free tin alloy finishes with SnPbfinishes. This dipping is different from dipping to within some distance of the body for thepurposes of solderability; solder dipping for purposes other than full replacement of pure tin andother Pb-free tin alloy finishes are beyond the scope of this document. It covers process andtesting requirements for robotic and semi-automatic dipping process but does not cover purelymanual dipping processes, due to the lack of understanding of the appropriate requirements forhand-dipping for tin whisker mitigation at this time.

This standard does not apply to piece-part manufacturers who build piece parts with a hot solderdip finish. It applies to refinishing performed by any other group, including a third partysupplier, production facilities at the supplier and other organizations, whenever the intent of thedipping is to have full coverage and replacement of Pb-free tin.

The intent of this standard is for suppliers and users to incorporate these requirements into theiroperations to provide a consistent and well-controlled process for product applications thatrequire significant control, typically Control Levels 2C or 3 of GEIA-STD-0005-2. Each usershall determine the applicability of this standard and the need for full replacement of the existingtermination finish. This standard does not guarantee a particular yield or reliability of pieceparts going through solder dipping. Some applications may have unique requirements thatexceed the scope of this standard, and should be specified separately.Pb-free tin piece parts which have been dipped in compliance with this standard are no longerconsidered to be Pb-free tin finished for the purposes of GEIA-STD-0005-2.
