In your case, a standard for cleanliness, the IPC/EIA J-STD-001, "Requirement for Solder Electrical and Electronic Assemblies" has your answer in section 8, "Cleaning Process Requirements." If you do not have a copy of this standard, please go to the IPC's site and buy one.
The IPC is the best source for standards for our industry, Electronics Assembly. Joe Russeau, Precision Analytical Laboratory, Inc. However, as I am the IPC chairman for the Ionic Conductivity Task Group I would encourage you and others to come to our meeting in the Fall at SMTAi to throw out some idea's. There are no IPC derived requirements or methods for component cleanliness at this time. It utilizes the Resistivity of Solvent Extract (aka ROSE) test, which is an improper application of that technique IMHO.
Two JEDEC standards I can recommend you begin your search with are JEDEC STD 22-B102E, and JESD9B, specifically section 8.1 which uses the words "metallization" to cover any conductive condition, including under-etched metal, crystallization, dendrites,and so forth.Īnyone can get the JEDEC standards by simply going to and registering it is free of charge.Īlso they are cheaper than sleeping pills, and more effective.Ĭurrently there is one standard that is applied for electronic piece parts and it is the GEIA-STD-006 post solder dip to replace final finish. To date I have not been able to find any standards regarding cleanliness specifications for ionics for electronic components specifically.Īre there for electronic component cleanliness in the industry currently or are there plans to review cleanliness requirements for components?Ĭomponent cleanliness is "sort of" covered within the JEDEC standards, but typically they will reference MIL-PRF-STDs for component cleanliness. I have been looking for cleanliness standards for electronic components but the only thing I have been able to find is for PWB cleanliness. We have a very stringent humidity and temp test from one of our OEM's that causes dendrites almost every time we run the test. I work as a supplier engineer in our automotive division and we are very concerned about cleanliness for electronic components.
