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
In this paper, a series of experiments was carried over to know the influence of specifically NaCl on BGA wetting given Head in Pillow (HiP) as result. Production Floor
We have an operational circuit board that was accidentally exposed to rainwater for a few hours. Is there a greater likelihood of failure? Jim Hall and Phil Zarrow, The Assembly Brothers, answer this question and share their expertise in the industry. Board Talk
The paper discusses testing and modeling program that aims to assess and quantify tin whisker growth on lead-free manufactured assemblies. Production Floor
In this study, we analyzed the effect that voltage bias has on dendrite growth both in clean PCBs and PCBs that were contaminated. Analysis Lab |
