The present design relates to pin bonding using welding on metallized ceramic (MC) substrates. Pins which are provided with a flange head or shoulder can be bonded on the MC substrate without heating the substrate using a special welding process. Bonding material at up to 1500 degrees F can be used between the pin flange and substrate land. One important advantage of this method is the provision of hermetically sealing the hole between the pin and the substrate.
