Patent ID: 7204008

Claim:
A method of making an electronics module, where said electronics module is to operate at one of a predetermined plurality of operating speeds, said method comprising: providing a plurality of integrated circuits; assembling an electronics module by demountably attaching selected ones of said integrated circuits to a module substrate; testing said demountably assembled module at a selected one of said operating speeds; if said module fails said testing: removing at least one of said integrated circuits determined to have caused said failure form said module substrate, replacing said at least one removed integrated circuit with another of said plurality of integrated circuits, and repeating said testing step and, if said module again fails said testing, said removing, replacing, and repeating steps, further comprising grouping said plurality of integrated circuits in accordance with said operating speeds, wherein: said step of assembling an electronics module comprises selecting said integrated circuits from one of said groups; and said selected one of said operating speeds corresponding to said one of said groups.
