Windshield Washer Interferes with ABS
In the development cycle of a certain automobile, it was found that the pump motor for the windshield washer was creating interference and causing an ABS warning light to activate. This vehicle's brake lines were coated with a new material which had a much higher conductivity than on older models. It was later determined that the pump motor was generating a transient that was … [Read more...]
New Method of Producing Transformers and Inductors
NASCENTechnology specializes in the development and manufacture of low profile, high reliability transformers and inductors using Low Temperature Co-Fired Ceramic (LTCC) materials and methods. LTCC indicates that the parts are fired at temperatures below 950°C, allowing for the use of thick film silver as the conductive material. This process eliminates the plastic bobbins, … [Read more...]
