Problems solved by technology

However, this system requires that the board under test contains only a single piece (LSI), which is not usually the case in partial disassembly for remanufacturing
Furthermore, instead of allowing the board under test to interface as normal, the board is made to interface indirectly through the Fukasawa test board, thus adding complexity in the fixture and additional means of handling inadvertent errors to account for

Embodiment Construction

[0017] The present invention generally relates to a system for remanufacturing circuit board assemblies and other electronic assemblies that requires selective removal of one or more components from the assembly, eg, to access portions of the assembly for repair or analysis. In general, remanufacturing processes with respect to circuit assemblies require disassembly and testing of the assembly and / or parts thereof consistent with the repair action to be taken. Then, depending on the tests or analyzes performed, the tested assembly is repaired by adjusting or replacing one or more parts or components, after which the parts are reassembled and tested.

[0018] Typically, electronic assemblies such as ECUs used in industrial or other demanding environments include active parts, such as printed circuit boards, and housings for protecting said active parts from the surrounding environment. Typically, therefore, the housing is removed to allow access to the active portion of the ass...

Abstract

A method for remanufacturing an electronic assembly allows the assembly to be disassembled, tested and reassembled despite certain components being permanently affixed to a housing of the assembly. The electronic assembly includes a circuit assembly within the housing. During remanufacture, a first portion of the housing is removed to expose a first side of the circuit assembly and a second portion of the housing is removed to expose a second side of the circuit assembly. When removing the second portion of the housing, one of the components of the circuit assembly may also be removed. Duringremanufacture a connector assembly including a replacement component substantially similar to the removed component, and including one or more pins connected to the replacement component and situatedto mate with one or more empty sockets of the circuit assembly is used to facilitate testing of the assembly.

Description

technical field [0001] This patent disclosure relates generally to the remanufacturing of electronic assemblies, and, more particularly, to a system for remanufacturing electronic assemblies in which one or more of the Component electronics. Background technique [0002] With the advent of integrated electronics, electronic circuits have largely eliminated mechanical and electromechanical features in many applications, reducing the maintenance and adjustment work associated with such applications. However, these electronic circuits, as well as the mechanical aspects of the circuit housings, attachment points, etc., still occasionally require maintenance, adjustment, or even replacement. For example, power circuits may be degraded by exposure to excessive heat. Vibration and other mechanical forces may affect the circuits and / or their enclosures or their connections to other circuit components. [0003] However, due to the relative permanence of integrated circuit assembli...
