- the present invention relates primarily to the manufacture of components by means of Vacuum Injection Molding, VIM.
- VIM Vacuum Injection Molding
- This uses a vacuum in the mold tool to suck the liquefied molding compound into the gap.
- the structure of the mold tool is selected in such a way that possible air pockets are avoided when the liquid mass is poured in, so that the mass completely fills the available space. There is no need for additional release films between the mass and the mold tool, so that sharp edges with a very small radius can be achieved. Because of the negative pressure, the mass is also drawn into small spaces.
- VIM represents a special form of the injection molding process, since the molding compound is usually liquid and has a lower viscosity than other processes.
- the liquid molding compound is fed in via an external pressure which, depending on the application, is then maintained during the cooling process.
- flashing in which the molding compound penetrates into the edge areas between parts of the mold tool. Therefore, sharp edges or very small radii are only possible to a limited extent with this method.
- a compressible film can also be placed on the mold tool. This can be removed after the process. In this case, however, the film itself has a certain thickness, as a result of which edges are limited in their radius. In addition, the film must fit snugly, i.e. it must not curl or deform in any other way during the process.
- FIG. 1 shows the arrangement of a multiplicity of side-emitting lasers as light-emitting components 1 on a leadframe 2 before the components 1 are separated.
- a single component 1 is shown in FIG. 3 in a spatial representation and in FIG. 4 in a spatial section.
- Each component 1 comprises a carrier 3, which is part of the leadframe 2 before the components 1 are separated and is made, for example, of metal such as copper, on which a laser diode 4 is arranged and electrically connected to wires 5 with contacts, of which only one is shown in FIG Contact 6 can be seen connected.
- the laser diode 4 is enclosed in a cavity 7 in an envelope 8 made, for example, from a duroplastic material such as epoxy, to which a reflective agent has been added, or a white-colored silicone. Over the envelope and in the cavity 7 is a cap
- the cavity 7 is open to a light exit surface 10 so that the light exit surface 10 is formed by the cap 9 .
- the carrier 3 has a step 11 on the side of the light exit surface 10, so that the carrier 3 is on the side of the light exit surface
- the 10 has an L-shaped contour in side view. That Material of the cap 9 covers both an upper side 29 of the envelope 8 and a front side 12 of the stage 11.
- the light exit surface 10 is practically perpendicular to a base area 13 of the component 1.
- the laser diode 4 is essentially cuboid, so that its frontal laser facet, hereinafter more generally referred to as exit surface 14 is also perpendicular to the base surface 13 of the component 1 and exit surface 14 and light exit surface 10 are thus practically parallel, insofar as this is permitted by the method for casting the cap 9 presented below.
- the components 1 are each arranged next to one another in rows 15 for production.
- a row 15 are, as can be seen in particular in Figure 2, apart from the rows 15 arranged at the edge, two components la and lb so in the longitudinal direction by, this is characterized by a double arrow 16, arranged next to each other that the respective Lichtaustrittsflä surfaces 10 face a parting line 17 .
- a printed circuit board substrate 2 is provided in a production step a) and the envelope 8 is cast in a production step b).
- a production step c the laser diodes 4 are arranged on the printed circuit board substrate 2, fastened and wired. This step can also be carried out before the casings 8 are cast.
- a manufacturing step d) the printed circuit board substrate 2 with the semiconductor elements is placed in a lower mold and in a manufacturing step e), an upper mold 18 is placed on the lower mold in such a way that the printed circuit board substrate 2 is received in a closed cavity in which are cavities for the caps to be cast.
- FIG. 5 schematically shows a section through two components lc and ld arranged on both sides of one of the parting lines 17 .
- the parting line 17 is formed by a bar 19 of the upper mold 18 generated.
- a negative pressure is generated in the cavities of the molding tool for the caps 9, shown hatched in FIG.

- a manufacturing step h) by forming the substrate with the semiconductor elements embedded in plastic and in a manufacturing step i) by separating the semiconductor elements. In this way, the individual edges are significantly narrower and the radius of curvature around the edge is reduced compared to production with foil.
- FIG. The radius RI can be made much smaller than in the prior art by means of the vacuum injection molding described above and has radii of less than 100 mih.
- FIGS. 6 and 7 show schematic representations of the component according to the invention as shown in FIGS. Figure 6 is a longitudinal section, Figure 7 is a plan view.
- FIGS. 8 and 9 show schematic representations of a further exemplary embodiment of a component 1 according to the invention in section and top view, respectively.
- stage 11 is omitted. This is possible through the above-described vacuum injection molding for casting the cap 9, since the strip
- the proposed method also allows the lead frame 3 to be different and in particular with a gear reduction to configure as shown in the side view of Figure 8.
- the reduction is located at the bottom right and is filled with the material of the envelope 8.
- the respective top views also show the slight return of the transparent material of the cap 9, which can be seen even more clearly in the top view of FIGS.
- These bulges, where the material of the printed circuit board 3 is exposed, comprise a long side -corresponding to the exit surface of the cap, which runs essentially parallel to the laser facet and two side surfaces connected to it which open at a shallow angle, for example in the area from 45° to 75°. This reduces possible tension during production and creates a smooth surface.
- FIGS. 10 and 11 show two further exemplary embodiments of components 1 according to the invention in a plan view.
- laser diodes 4a, 4b, 4c of different colors are arranged on a common substrate 21; in the exemplary embodiment in FIG. 11, laser diodes of different colors are arranged on separate substrates 22a, 22b, 22c.
- the exit surface of the cap 9 is arranged parallel to all three laser facets.
- the injection molding allows the surface to be brought very close to the laser facets, so that the distance between the surface of the cap and the laser facets is in the range of less than 100 ⁇ m, possibly up to a few 10 ⁇ m. This can be due, among other things, to the fact that injection molding has eliminated the large radii of curvature in the area of the exit surface of the cap.
- a further advantage can result from the fact that the elimination of the previously occurring large radii of curvature in the area of the exit surface of the cap also allows a greater distance between the light exit surface and the laser facet. In previous components it can happen that Curvatures of the light exit surface protrude into the light cone of the laser diodes and have a negative impact on it.
- One advantage of a larger distance can be that the light cone from the laser is already larger. As a result, the beam intensity of the laser can be reduced on the one hand, and on the other hand dust particles or similar impurities on the light exit surface heat up less. The service life of the optical surface or light exit surface can be increased in this way.

- the molding material which is located on the rear wall of the carrier 3 in the area of the edges, can also be seen in this sectional view. This is where the separation takes place during production, so that it is expedient to use easily separable mold material at these positions.
- Figure 15 illustrates their production.
- a slide 24 of the lower or upper mold is first brought into a first, forward position as shown in FIG.
- the slide 24 includes a concave recess 25 for producing the convex lens of the light exit opening 10.
- the slide 24 is brought into a second, rear position in the direction of the arrow 26 so that it releases the lens and can be shaped.
- FIG. 16 shows a further exemplary embodiment of a component 1 according to the invention in a sectional view.
- the light exit opening 10 here comprises one designed as a lens Insert 27 made of glass, for example a "Fast Axis Collimator" lens (FAC).
- the insert 27 is placed in a corresponding manufacturing step d-2) in a manufacturing step d) after the insertion of the circuit board substrate 2 into the lower mold Place the lower molding tool or the upper molding tool 18 and cast in.
- the molding tool should be elastically molded in the area of the lens in order to avoid damage or destruction.
- the molding tool may include or consist of polydimethylsiloxane (PDMS). be formed in order not to damage the insert 27.
- PDMS polydimethylsiloxane
- the insert 27 does not touch the mold on its light exit side, in order to prevent damage to the light exit side.
- the mold can also be designed in this way be that it seals the area to be cast around the lens, so that the cap 9 at the ge wünsc correct position and in the desired shape and size.
- FIGS. 17 and 18 show schematic representations of a further exemplary embodiment of a component 1 according to the invention in section and in plan view.
- laser diodes 4a, 4b, 4c of different colors are connected to a beam combiner 28, which is arranged between the laser diodes 4a, 4b, 4c and the light exit opening 10. This can be applied to the leadframe in a first manufacturing step. Subsequently JOd he is surrounded by the transparent cap 9 completely.
- the beam combiner 28 can be designed in particular to combine the light emitted by the laser diodes 4a, 4b, 4c and to deflect it by approximately 90° as in the case shown.
- the beam combiner 28 can include, for example, mirrors or reflective elements that deflect the individual light beams. Accordingly, the combined light beam cannot, for example, exit the component along the main emission direction of the laser diodes 4a, 4b, 4c or from the light exit opening mentioned at the outset, but can exit the component, for example along the dashed line, as in the illustrated case.
- the combined light is deflected in a direction that is not shown and/or the beam combiner 28 can also include, for example, a plurality of mirrors or reflecting elements that deflect the combined light several times.
