Definitions
- the present invention relates to a method for producing a solder connection between at least two contact partners of a contact arrangement, in which a solder material molding is arranged at a distance from the contact arrangement, the solder material molding is at least partially melted, and the at least partially melted solder material molding is flung against the contact arrangement in this way that to form an electrically conductive connection in a connection area, both contact partners are wetted.
- solder connection between two contact partners of a contact arrangement
- the contact partners being designed as contact surfaces and enclosing an angle of 90 °.
- a solder material shaped piece formed as a solder ball by means of a capillary between the two contact partners in such a way that there is both a contact between the two contact surfaces and the capillary.
- the solder ball is pressed against the contact surfaces by means of the capillary. This contact has to be be maintained until, as a result of melting the solder ball by means of laser energy, there is wetting of the contact surfaces and the resulting adhesive forces which secure the solder material in the connection position.
- the manner of generating the contact pressure between the solder ball and the contact surfaces described above means that the capillary must be positioned directly in the region of the contact arrangement in order to produce the solder connection. On the one hand, this necessitates a highly precise positioning of the capillary, on the other hand, this means that the contact arrangement is easily accessible.
- the present invention is based on the object of proposing a method for producing a solder connection between two contact partners of a contact arrangement which are not arranged in the same plane, which on the one hand requires less positioning effort for positioning the capillary and on the other hand can also be carried out at a distance from the contact arrangement, so that the accessibility requirements of the contact arrangement may also be lower.
- a solder material molded piece is arranged at a distance from the contact arrangement in order to produce the solder connection and, after an at least partial melting of the solder material molded piece, is hurled or shot against the contact arrangement.
- This centrifugal movement or ballistic movement of the at least partially melted solder material molding takes place in such a way that both contact partners are wetted when or as a result of hitting the contact partner (s).
- an electrically conductive connection is formed by wetting both contact partners.
- solder material not only conventional materials, such as metallic solder alloys, but in principle all materials that enable an electrically conductive connection between contact partners, such as conductive plastics, come into consideration as solder material.
- solder material molding and the capillary is no longer necessary to produce the solder connection. Rather, the at least partially melted solder material molding can be placed in the area of the contact arrangement without touching the capillary.
- the solder material shaped part can only be partially melted or also completely melted and can be hurled or shot against the contact arrangement. It is only essential that, as a result of the impact of the solder material on at least one contact partner of the contact arrangement, both contact partners are wetted.
- the method proves to be particularly advantageous if the at least partially melted solder material molding is thrown into a contact gap formed between the contact partners of the contact arrangement.
- it is possible, depending on the formation of the gap, to counteract the capillary force counteracting the wetting of the entire contact surface of the contact arrangement with the mass force of the solder material, in order to achieve a reliable solder connection even in the case of rather unfavorably designed contact arrangements.
- a reliable solder connection is possible by using the method if the at least partially melted solder material molded piece is thrown in the direction of the bisector of the gap angle formed between the contact partners in the contact gap.
- the choice of the direction of centrifugation corresponding to the bisector of the wedge gap proves to be particularly advantageous if the contact partners to be wetted are flat with contact surfaces of approximately the same size.
- the method thus enables a defined relative arrangement of the contacts to be contacted with one another in a first step
- the wire conductor is forced into contact with the contact area as a result of the impact of the solder material on the wire conductor. In this way, it is also possible to dispense with a contact between the connecting tool and the wire conductor during the connection establishment in the case of a wire conductor connection.
- 1 to 6 show a basic illustration of the successive method steps when carrying out the method for producing a solder connection between two contact surfaces of a contact arrangement forming a contact gap;
- Fig. 8 shows the application of the method for producing a
- FIG. 9 shows the arrangement shown in FIG. 8 in a top view
- Fig. 10 shows the application of the method for producing a
- FIG. 11 shows the application of the method for producing a solder connection in a contact arrangement formed from a contact surface and a wire conductor.
- FIGS. 1 to 6 shows, on the one hand, a solder material application device 20 that can be used to carry out the method and, on the other hand, the use of the method for producing a solder connection in a contact arrangement 21 whose
- Contact surfaces 22, 23 formed contact partners are arranged so that they form a wedge gap 24.
- the gap angle ⁇ of the wedge gap 24 is approximately 90 °.
- solder material application device 20 with a guide channel 26 formed in an application mouthpiece 25, which serves for receiving and guiding a solder material shaped piece 27, which is designed here in spherical form.
- the solder material molded piece 27 is moved by gravity or active application, for example by means of compressed gas, into a funnel-shaped discharge area 28 of the guide channel 26 and there it is brought into contact with an opening edge 29 of the discharge area 28.
- the opening edge 29 is designed in the manner of a valve seat and, together with the shaped solder material piece 27 on the opposite side, forms an essentially fluid-tight closure of the dispensing area 28.
- the solder material molding 27 has entered the guide channel 26 of the application mouthpiece 25, it comes into contact with the opening edge 29 of the dispensing area, as shown in FIG. 2.
- the solder material molding 27 After the positioning of the solder material molding 27 relative to the contact arrangement 21, as shown in FIG. 3, the solder material molding is subjected to energy, for example by means of laser energy, which causes the solder material molding 27 to at least partially melt.
- the ejection process causes a projectile-like movement of the at least partially melted solder material molded piece 27 in the direction of the contact arrangement 21 along the central axis 3 1 of the guide channel 26, the central axis 3 1 coinciding approximately with the bisector of the gap angle in the exemplary embodiment shown here ,
- the contact surfaces 22, 23 are at least partially wetted in accordance with the proportion of the melted volume of the solder material molded part 27.
- a complete wetting of the contact surfaces 22, 23 can be ensured in that, after the impact of the solder material molding 27 on the contact arrangement 21, the solder material molding 27 is subjected to repeated energy up to the point of complete melting.
- the ejection axis deviates from an angle bisector 35 of a wedge gap 36 formed by the contact arrangement 32 toward the larger contact surface 34, so that due to the impact of the at least partially melted solder material molded piece 27, the size of the contact surfaces is correspondingly different with respect to the wetting surface 33, 34 results in coordinated wetting.
- FIG. 8 shows the application of the method for producing a solder connection between contact surfaces 37, 38 of a contact arrangement 39 which forms a parallel gap 40.
- the application shown in FIGS. 8 and 9 relates, for example, to the contacting of a chip 41 with peripherally arranged contact areas 37 on a substrate 42 with likewise peripherally arranged contact areas 38.
- the substrate 42 is located with the Contact surfaces 38 facing the chip 41 on a base 65.
- the chip 41 is arranged above the substrate 42 and at a defined distance a from it, the contact surfaces 37 of the chip being in overlap with the associated contact surfaces 38 of the substrate.
- the chip 41 is held in this defined relative position relative to the substrate 42 by a vacuum plate 43 which is provided with suction openings 45 in its suction surface 44 and which causes the chip 41 to adhere to the vacuum plate 43 by means of a vacuum applied to a connection opening 46 of the vacuum plate 43 ,
- the substrate arrangement 47 consisting of the chip 41 and the substrate 42 is defined in its relative positioning, as described above. Subsequently, as is shown in particular in FIG. 9, the substrate arrangement 47 is surrounded by a solder material application device 48 in such a way that application areas 49 are assigned to the individual contact arrangements 39, the structure of which is shown in FIGS. 1 to 7 Correspond to solder material application device 20.
- the central axes 31 of the application areas 49 are oriented essentially parallel and centrally to the contact surfaces 37, 38, that is to say arranged approximately coaxially with the central gap axes 62 of the contact arrangements 39.
- the at least partially melted solder material shaped pieces 27 are ejected, so that subsequently an impact of the at least partially melted solder material shaped piece 27 shown in FIG 8 shows wetting of the contact surfaces 37, 38 shown on the left to form a solder connection 50.
- the contact sleeve 52 can be a plated-through hole in a substrate 54, into which a connecting conductor of an electronic component, such as a semiconductor component 55, is inserted, which is designed as a wire conductor 53.
- the connection arrangement shown in FIG. 10 between the semiconductor component 55 and the substrate 54 thus corresponds to the connections made in so-called SMD (surface-mounted device) technology for producing component groups.
- the solder material application device 20 with the central axis 3 1 of the guide channel 26 is positioned essentially relative to the contact sleeve 52 such that the central axis 3 1 essentially extends coaxially with a central axis 57 of the contact sleeve 52.
- the central axis 57 essentially coincides with the course of the wire conductor of the wire conductor 53 in the contact sleeve 52.
- FIG. 11 shows the production of a solder connection 64 shown in dashed lines in a contact arrangement 58 comprising a contact surface 59 of a substrate 60 and a wire conductor 61.
- the contact arrangement 58 is acted upon with the at least partially melted solder material fitting 27 from a position of the solder material application device 20 in which the central axis 3 1 of the application mouthpiece 25 coinciding with the ejection direction intersects the wire conductor and is arranged transversely to the contact surface 59.
- This positioning of the application mouthpiece 25 results in an intermediate arrangement of the wire conductor 61, so that the wire conductor 61 is pressed against the contact surface 59 by the impact of the at least partially melted solder material molded part 27 and an essentially gap-free contact between the wire conductor and the contact surface 59 is made possible ,
