ABSTRACT:
A solder joint between a capacitive element and a ferrule of a filtered feedthrough assembly for an implantable medical device is formed from a solder pre-form mounted on a portion of an external surface of the capacitive element, which portion of the external surface may be overlaid with a layer including a noble metal. Another solder joint may be formed between the capacitive member and each feedthrough pin; and, for an assembly including a plurality of feedthrough pins, each of the other solder joints may be formed from a solder pre-form mounted onto the external surface of the capacitive element by inserting each pin through a corresponding ring of a plurality of rings connected together to form the solder pre-form.
