Continuous extrusion process for manufacturing a Z-directed component for a printed circuit board
View Patent ↗A method for manufacturing a Z-directed component for insertion into a mounting hole in a printed circuit board according to one example embodiment includes simultaneously extruding a plurality of materials in the cross-sectional shape of the Z-directed component to form an extruded object with the plurality of materials arranged relative to each other in their operative positions for the Z-directed component. The extrusion of a first portion of at least one of the materials in the extruded object is staggered relative to the extrusion of a second portion of the at least one of the materials in the extruded object. At least a segment of the extruded object is fired. The fired segment forms the Z-directed component insertable into a mounting hole in a printed circuit board.
1. A method for manufacturing a Z-directed component for insertion into a mounting hole in a printed circuit board, comprising:
simultaneously extruding a plurality of materials in the cross-sectional shape of the Z-directed component to form an extruded object with the plurality of materials arranged relative to each other in their operative positions for the Z-directed component;
staggering said extrusion of a first portion of at least one of the materials in the extruded object relative to said extrusion of a second portion of said at least one of the materials in the extruded object; and
firing at least a segment of the extruded object, the fired segment forming the Z-directed component insertable into a mounting hole in a printed circuit board.
2. The method of claim 1 , wherein the first portion of said at least one of the materials extends to a top surface of the Z-directed component and is spaced from a bottom surface thereof and the second portion of said at least one of the materials is spaced from the top surface of the Z-directed component and extends to the bottom surface thereof.
3. The method of claim 1 , wherein said staggering includes dispensing said at least one of the materials from a plurality of slats in the path of extrusion and imposing a predetermined delay between a first set of the slats and a second set of the slats to vary the timing of extrusion of said material.
4. The method of claim 3 , wherein the delay is imposed by varying (1) the position of the first set of slats relative to the second set of slats, (2) the length of a material path feeding the first set of slats relative to the length of a material path feeding the second set of slats, (3) the timing of material flow to the first set of slats relative to the second set of slats, or (4) a combination thereof.
