Abstract

A fixture assembly for use with fine wire laser soldering. The fixture includes a holding and support fixture and a wire securing and tensioning fixture. The holding and support fixture has a wire holding member and a retention member. The wire holding member and the retention member cooperate with wires prior to the wires being soldered. The wire securing fixture has wire tensioning projections and wire retention members. The wire tensioning projections and wire retention members cooperate with the wires to provide tension to the wire prior to the wires being soldered.

First claim

The invention claimed is:

1. A fixture assembly for use with fine wire laser soldering, the fixture comprising:
a holding and support fixture having
(a) a wire holding member, and
(b) a retention member that (i) extends from a first portion of the wire holding member, and (ii) has a U-shaped configuration, a base of the U-shape having a wire retention section, the wire holding member and the retention member cooperating with wires prior to the wires being soldered; and

a wire securing and tensioning fixture having wire tensioning projections and wire retention members, the wire tensioning projections and wire retention members cooperating with the wires to provide tension to the wire prior to the wires being soldered,

wherein the wire retention section has adhesive coupling which cooperates with the wires to temporarily secure the wires in position.

2. A The fixture assembly for use with fine wire laser soldering, the fixture comprising:
a holding and support fixture having a wire holding member and a retention member, the wire holding member and the retention member cooperating with wires prior to the wires being soldered; and
a wire securing and tensioning fixture having wire tensioning projections and wire retention members, respective wire tensioning projections being provided in rows, with three wire tensioning projections in each row, the wire tensioning projections and wire retention members cooperating with the wires to provide tension to the wire prior to the wires being soldered.

3. The fixture assembly as recited in claim 2 , wherein the wire holding member of the holding and support fixture has a wire-alignment device positioned proximate a first end of the wire holding member.

4. The fixture assembly as recited in claim 3 , wherein the wire-alignment device is positioned in a wire alignment device receiving recess of the holding and support fixture.

5. The fixture assembly as recited in claim 2 , wherein the holding and support fixture is removably mounted to a base of the fixture assembly.

6. The fixture assembly as recited in claim 2 , wherein a respective wire retention member of the wire retention members is provided in line with each respective row of the rows of wire tensioning projections.

7. The fixture assembly as recited in claim 6 , wherein the wire retention members are spaced from the wire tensioning projections, the wire retention members being arranged in a staggered configuration to allow for closer spacing of the rows of wire tensioning projections.

8. The fixture assembly as recited in claim 6 , wherein middle wire tensioning projections of each row of wire tensioning projections are provided on a movable member, the moveable member being movable in a direction which is perpendicular to the plane formed by each of the rows of wire tensioning projections.

9. The fixture assembly as recited in claim 6 , wherein a substrate adjusting fixture is provided to allow movement of a substrate relative to the wires.

10. The fixture assembly as recited in claim 9 , wherein the substrate adjusting fixture has a first member and a second member which is movable relative to the first member, the first member having a first substrate receiving cavity, the second member having a second substrate receiving cavity, the first and second substrate receiving cavities being dimensioned to receive the substrate therein.

11. The fixture assembly as recited in claim 9 , wherein the first member is connected to the second member by pulling-adjustment hardware and pushing-adjustment hardware, wherein as the adjustment hardware is moved, a free end of the second member is forced to move relative to a fixed end of the first member, causing the free end of the second member to be moved relative to a first end of the first member, causing the second substrate receiving cavity to be moved relative to the first cavity substrate receiving cavity.

12. A wire securing and tensioning fixture comprising,
wire tensioning projections, respective wire tensioning projections being provided in rows, with three wire tensioning projections in each row, middle wire tensioning projections of each row of wire tensioning projections being provided on a movable member, the moveable member movable in a direction which is perpendicular to the plane formed by each of the rows of wire tensioning projections, and
wire retention members, the wire tensioning projections and wire retention members cooperating with the wires to provide tension to the wire prior to the wires being soldered.

13. The fixture assembly as recited in claim 12 , wherein a respective wire retention member of the wire retention members is provided in line with each respective row of the rows of wire tensioning projections, the wire retention members being arranged in a staggered configuration to allow for the row of wire tensioning projections.
