Title: Avinash S Adwalpalker: Innovator in Metallurgical Processes
Introduction
Avinash S Adwalpalker is a notable inventor based in Stormville, NY (US). He has made significant contributions to the field of metallurgical processes, holding 2 patents that showcase his innovative approach to technology.
Latest Patents
One of his latest patents is the "Stripped Gold Plating Process." This method involves fabricating metallurgical contacts for thermocompression bonds to a metallized ceramic substrate, which is essential for mounting and electrically contacting semiconductor chips. The process includes placing a nickel layer on the substrate, covering it with an immersion layer of gold, and selectively removing the gold from specific locations using a chemical stripper. Heavy gold is then electroplated on the desired locations, followed by heat treatment before the placement of thermocompression-bonded contacts.
Another significant patent is the "Re-work Method for Removing Extraneous Metal from Ceramic Substrates." This method addresses the removal of extraneous plated metal layers from ceramic substrates containing refractory metal areas. The substrate is heated to strengthen the bond between the plated metal layer and the refractory metal areas while weakening the bond with the extraneous metal. The process involves immersing the substrate in a liquid and applying localized ultrasonic energy to the areas needing removal.
