DEFINITION

Classification: 228/262.1

Critical work component, temperature, or pressure:

(under subclass 101) Process including (a) use of specifically claimed work material, (b) applying force between the meeting faces to effect bonding, claimed expressly in precise, numerical language, or (c) applying thermal energy to the meeting faces or to the filler, claimed expressly in precise, numerical language with regard to the thermal level (temperature) or the rate of applying thermal energy.

(1) Note. Lead (Pb), zinc (Zn), tin (Sn), chromium (Cr), germanium (Ge), manganese (Mn), as well as material claimed as "metal," are materials included in this and the indented subclasses, in addition to those specifically named in those titles or definitions.
