An Alternative PCB Architecture for High-Speed Chip-to-Chip Signal Transmission
Think copper hits its wall at 10 Gbps? Think again. A novel chip package achieves 40 Gbps by routing high-speed signals through the top side.
Industrial processes have always demanded the utmost repeatability, to maximize yield within accepted quality limits. We reveal secrets of what machine specification sheets really mean, and how to read them.
Nitrogen's Effect on Pb-free Soldering
How and why the inert atmosphere lowers soldering temperatures, improves wetting and reducing voids.
Potential for Whisker Formation in Pb-Free Electroplated Connector Finishes
Of 20 lead-free electrodeposited connector finishes studied, a matte finish or bright pure tin over a nickel barrier were found to be least susceptibile to tin whiskering.
