Title: The Innovative Contributions of Roger L Krechmery
Introduction
Roger L Krechmery is a notable inventor based in Mentor, OH (US). He has made significant contributions to the field of pressure transducers, holding 2 patents that showcase his innovative approach to engineering challenges. His work has had a lasting impact on the design and functionality of electronic pressure transmitters.
Latest Patents
Krechmery's latest patents include a method for isotropic etching of silicon strain gages. This method involves etching a silicon diffused resistance pressure transducer assembly mounted on a glass base. The process creates a thin flexible area on the transducer while maintaining a thick rigid area where it is attached to the glass base. The transducer is first bonded to a tubular glass base, allowing for an open area on the backside that is filled with an isotropic etchant. This etchant effectively removes silicon material without affecting the glass, resulting in a functional and efficient design.
Another significant patent is related to a glass-to-metal seal for a pressure-sensitive silicon chip. This invention involves indirectly bonding the silicon chip to a stainless steel housing through an intermediate holder assembly. This innovative approach prevents thermal cracking of the silicon chip, which can occur due to differences in thermal expansion. The assembly includes a borosilicate glass tube with the silicon chip bonded to it, which is then soldered to a nickel-iron alloy holder. This method ensures the integrity of the components during assembly and operation.
