Abstract
Disclosed is an apparatus for separating interconnects between, for example, a card and a substrate. The apparatus includes one or more rotationally biased (e.g., spring-loaded, etc.) partial-circle structures (e.g., blades, squeegee, plow, etc.) and one or more temperature-sensitive releases connected to the partial-circle structures. The partial-circle structures are positioned to rotate and separate the interconnects when released by the temperature-sensitive releases. The invention can also include solder reservoirs positioned to receive solder from the interconnects separated by the partial-circle structures.
Claims16
An apparatus comprising:
- a frame;
- at least one rotationally biased partial-circle structure above said frame;
- and
- at least one temperature-sensitive release operably connected to said at least one rotationally biased partial-circle structure so as to prevent rotation of said at least one rotationally biased partial-circle structure,
- said frame holding a workpiece having two parts mechanically and electrically connected by interconnects and, at a predetermined temperature, said at least one temperature-sensitive release releasing said at least one rotationally biased partial-circle structure such that said at least one partial-circle structure rotates and passes between said two parts of said workpiece, sweeping at least some of said interconnects out from between said two parts of said workpiece.
An apparatus comprising:
- a frame;
- a plurality of rotationally-biased partial-circle structures above said frame;
- and
- a corresponding plurality of temperature-sensitive releases operably connected to said plurality of rotationally biased partial-circle structures so as to prevent rotation of said rotationally biased partial-circle structures,
- said frame holding a workpiece having two parts mechanically and electrically connected by interconnects and, at a predetermined temperature, at least one of said temperature-sensitive releases releasing at least one of said rotationally biased partial-circle structures such that said at least one of said rotationally biased partial-circle structures rotates and passes between said two parts of said workpiece, sweeping at least some of said interconnects out from between said two parts of said workpiece.
An apparatus comprising:
- a frame;
- a plurality of rotationally-biased partial-circle structures above said frame and having overlapping rotational paths;
- and
- a corresponding plurality of temperature-sensitive releases operably connected to said plurality of rotationally biased partial-circle structures so as to prevent rotation of said rotationally biased partial-circle structures,
- said frame holding a workpiece having two parts mechanically and electrically connected by interconnects as said apparatus is subjected to a series of increasingly higher predetermined temperatures and, at each one of said predetermined temperatures in said series, a different one of said temperature-sensitive releases releasing a different one of said rotationally biased partial-circle structures such that said different one of said rotationally biased partial-circle structures rotates and passes between said two parts of said workpiece, sweeping at least some of said interconnects out from between said two parts of said workpiece.
