The Effect of Thermal Cycling Dwell Time on Reliability of Pb-free Solder Alloys
The Effect of Thermal Cycling Dwell Time on Reliability of Pb-free Solder Alloys
This paper presents the initial results from an experimental program designed to compare thermal cycling results for high-performance solder alloys using an extended dwell of 60 minutes to a typical short dwell time of 10 minutes. The 10-minute dwell data were generated in the initial phase oftesting and published previously.

Process-Reliability Relationships of Low-Temperature Solders and ECAs
Process-Reliability Relationships of Low-Temperature Solders and ECAs
This paper studies the process-performance-reliability relationships for Sn-Bi-Ag and Sn-In solders on additively printed copper metallization.
Analysis Lab

Lower-Temperature Lead-Free Solder Paste for Wafer-Level Package
Lower-Temperature Lead-Free Solder Paste for Wafer-Level Package
Lower-temperature paste can be reflowed under a relatively lower peak temperature profile and outperform SAC305 paste in the current WLP256 application.
Materials Tech

Copper Electrodeposition By Hydrogen Evolution Assisted Electroplacing
Copper Electrodeposition By Hydrogen Evolution Assisted Electroplacing
A technique called hydrogen evolution assisted electroplating, has shown enhancement to the deposition rate of copper compared to galvanostatic conventional electroplating methods.
Production Floor

Conformal Coating Testing in Various Test Environments
Conformal Coating Testing in Various Test Environments
This paper compared these three environments in terms of how well they characterize conformal coatings.
Analysis Lab

Moisture Barrier Bag Issues
Moisture Barrier Bag Issues
Moisture sensitive chip components have been exposed to the atmosphere beyond specification. Can they be packaged and sealed with desiccant?
Board Talk

Implementation of Assembly Processes for Low-Melting Point Solder Pastes
Implementation of Assembly Processes for Low-Melting Point Solder Pastes
This paper discusses the need for low-temperature solders and process-ability of solder pastes with three novel alloys against the industry standard.
Materials Tech

Robotic Systems Perform Experiments Speeding Up Research
Robotic Systems Perform Experiments Speeding Up Research
Robotic systems can perform experiments without fatigue, speeding up research. Robots execute experimental steps with greater consistency than humans. As explained recently in the journal Science Robotics, robots are rapidly, "Transforming Science Labs into Automated Factories of Discovery."
