I am looking for any information on immersion tin or immersion gold processes pertaining to the PCB manufacturing process. Specifically I'm interested in any studies comparing Immersion Tin or Immersion Gold vs. HASL finishes in the application of micro electronics. Thanks, Rick JacksonRick Jackson

You might get this publication: "Implementing Cleaner Printed Wiring Board Technologies: Surface Finishes" (EPA 744-R-00-002); it can be ordered from the Pollution Prevention Information Clearinghouse online through the EPA Website or download from www.epa.gov/dfe. The Design for the Environment EPA project did a good job in their "Making Holes Conductive" project.

Immersion Tin is primarily a three-step process: Cleaning-Microetching-Immersion Tin. But Some suppliers give an option of conditioning the copper surface before Immersion Tin. Please could someone clarify whether I should go for conditioning step before Immersion Tin?
