Abstract
Abstract Apparatus, and a related method for its operation, for integrating selected multiple assembly and repair operations of electronic component packages, such as printed wiring board assemblies (PWBAs), at a single multi-function workstation. Each PWBA product is uniquely identified by a bar code or similar inscription, and the identification permits product data to be retrieved from a factory or depot database. The retrieved product data controls the various operations to be performed, such as positioning and soldering of surface-mounted components, inspection for defects, desoldering of defective components, and reinstallation of replacement components.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
97 words
A method of operation of a multi-function workstation for assembling and repairing printed wiring board assemblies (PWBAs), comprising the steps of: unambiguously identifying a PWBA from product code markings on the PWBA; retrieving product data relating to an identified PWBA; inspecting the PWBA at the workstation, based in part on the retrieved product data, and identifying any defects in the PWBA; and removing and replacing a defective component in the PWBA with minimal operator intervention; wherein all of the foregoing steps are performed at a single integrated multi-function workstation and are driven by the retrieved product data.
Claim 2
Independent Claim
97 words
A method of operation of a multi-function workstation for assembling and repairing printed wiring board assemblies (PWBAs), comprising the steps of: unambiguously identifying a PWBA from product code markings on the PWBA; retrieving product data relating to an identified PWBA; inspecting the PWBA at the workstation, based in part on the retrieved product data, and identifying any defects in the PWBA; and removing and replacing a defective component in the PWBA with minimal operator intervention; wherein all of the foregoing steps are performed at a single integrated multi-function workstation and are driven by the retrieved product data.
Claim 3
Dependent Claim
30 words
A method as defined in claim 1, wherein the step of removing and replacing a defective component includes: removing a conformal coating from the PWBA; and desoldering the defective component.
Claim 4
Dependent Claim
34 words
A method as defined in claim 2, wherein the step of removing and replacing a defective component further includes: positioning a replacement component on the PWBA; and soldering the replacement component to the PWBA.
Claim 5
Dependent Claim
139 words
A multi-function workstation for assembling and repairing printed wiring board assemblies (PWBAs), comprising: a single workstation site and a plurality of component means situated about said single workstation site in a manner permitting each of said component means to operate at said single workstation site; said component means including means for unambiguously identifying a PWBA from product code markings on the PWBA; said component means also including means for retrieving product data relating to an identified PWBA; said component means also including means for inspecting the PWBA at the workstation, based in part on the retrieved product data, and identifying any defects in the PWBA; and said component means also including means for removing and replacing a defective component in the PWBA with minimal operator intervention; wherein all of the component means are driven by the retrieved product data.
Claim 6
Dependent Claim
139 words
A multi-function workstation for assembling and repairing printed wiring board assemblies (PWBAs), comprising: a single workstation site and a plurality of component means situated about said single workstation site in a manner permitting each of said component means to operate at said single workstation site; said component means including means for unambiguously identifying a PWBA from product code markings on the PWBA; said component means also including means for retrieving product data relating to an identified PWBA; said component means also including means for inspecting the PWBA at the workstation, based in part on the retrieved product data, and identifying any defects in the PWBA; and said component means also including means for removing and replacing a defective component in the PWBA with minimal operator intervention; wherein all of the component means are driven by the retrieved product data.
Claim 7
Dependent Claim
44 words
A multi-function workstation as defined in claim 4, wherein the means for removing and replacing a defective component is provided with a plurality of sub-systems, including: sub-system means for removing a conformal coating from the PWBA; and sub-system means for desoldering the defective component.
Claim 8
Dependent Claim
38 words
A multi-function workstation as defined in claim 5, wherein the means for removing and replacing a defective component further includes: sub-system means for positioning a replacement component on the PWBA; and sub-system means for soldering the replacement component.
Claim 9
Independent Claim
66 words
An apparatus for assembling and repairing printed wiring board assemblies (PWBAs), comprising: a single workstation site and a plurality of processing systems situated about said single workstation site in a manner permitting each one of said plurality of processing systems to operate at said single workstation site; said plurality of processing systems including a PWBA identification system, a PWBA assembly system, and a PWBA inspection system.
Claim 10
Independent Claim
66 words
An apparatus for assembling and repairing printed wiring board assemblies (PWBAs), comprising: a single workstation site and a plurality of processing systems situated about said single workstation site in a manner permitting each one of said plurality of processing systems to operate at said single workstation site; said plurality of processing systems including a PWBA identification system, a PWBA assembly system, and a PWBA inspection system.
Claim 11
Dependent Claim
17 words
The apparatus of claim 7 wherein said plurality of processing systems further includes a PWBA reworking system.
Claim 12
Dependent Claim
38 words
