The understanding of the growth mechanism for tin whiskers and what mitigation strategies can be employed to reduce their propagation. Analysis Lab
In this study, two Pb-free-compatible laminates were tested, with one dicy-cure non-Pb-free-compatible as control. Analysis Lab
A fabricator recently notified us that during the ENIG plating process, several pads had been “skipped” and missed on a number of boards. The fabricator would like to add OSP to the pads that are missing the ENIG. Is this acceptable? Board Talk
This paper covers the iNEMI technical subcommittee test for creep corrosion using a flowers-of-sulfur based qualification test. Analysis Lab
As lead-free alloys shift into high reliability electronics, the issue of tin whisker growth remains a primary concern among those in the industry. Analysis Lab
Which storage method will better protect against corrosion, nitrogen or super dry? Regardless of the methodology you use, you want to do it in compliance with IPC 1602, which covers storage and handling of circuit boards. Jim Hall and Phil Zarrow, The Assembly Brothers, answer this question. Board Talk
At our SMT facility we currently control ambient temperature, relative humidity and particle count. Is particle count a good parameter to control? The Assembly Brothers, Phil Zarrow and Jim Hall, discuss this question. Board Talk
This paper describes a corrosion resistant server design suitable for reliable operation in a free-air cooling data center. Production Floor
A few of our components have leads with a silver finish. Will silver cause solder embrittlement? Is removal of silver needed or can it be soldered using 63/37 solder? Phil Zarrow and Jim Hall, The Assembly Brothers, discuss this question and scenario. Board Talk
This paper will discuss an experiment that was performed to investigate the effects of "contaminants" that could be measured with SIR testing. Analysis Lab |
