Wireless power transfer has been around for a long time. The “crystal set” or “crystal radio” over 100 years ago used the power carried in the radio signal to produce sound without any amplification or receiving circuit power source. Early spark gap transmitters also used tuned wireless power transmission. Now the circuitry is more sophisticated […]

What are the benefits of screw machine interconnects?
As Principal Engineer for a large connector manufacturer, each day I am challenged by electrical engineers and mechanical engineers to help bridge their leading edge technology from one module to another. I remember years ago, when the pin grid array went obsolete to the emerging QFP quad-flat pack, people said that “screw machine was a […]
