Title: Otmar H Boser: Innovator in Solder and Capacitor Testing

Introduction

Otmar H Boser is a notable inventor based in Scarsdale, NY (US). He holds a total of 3 patents that showcase his contributions to the fields of materials science and electrical engineering. His work has significantly impacted the development of solder materials and testing methods for electronic components.

Latest Patents

One of his latest patents is for a dispersion strengthened lead-tin alloy solder. This improved solder contains up to about 5 vol. percent of small particles of a metal sulfide or a nickel-tin intermetallic, enhancing its performance and reliability. Another significant patent involves a method for nondestructive testing of multilayer ceramic capacitors. This method utilizes a bias voltage to determine the presence or absence of delaminations in capacitors exhibiting piezoelectric effects only during poling. The capacitor is inserted into an impedance bridge, where a bias voltage of 1 to 2.5 times the rated voltage is applied, and the impedance is measured as a function of frequency. A lower than expected impedance indicates a defective capacitor.
