Problems solved by technology

In addition, during the injection molding process, due to the high injection pressure and high viscosity of the liquid plastic material, or possibly due to the high temperature of the liquid plastic material, mechanical deformation of the lead frame (contact element) is caused, which leads to lead frame and SMD Damaged or disintegrated soldered connections between components

Embodiment Construction

[0023] exist figure 1 A part of a lead frame 1 is shown in , which has two contact lugs 2 which have a bonding location 3 at their respective ends. The connection point 3 is used for mounting and contacting the SMD component 4 there, so that the SMD component 4 is electrically connected via the contact strip 2 .

[0024] The lead frame 1 is provided with an encapsulation 5 made of plastic material, which is open 1 in the region of the contact bridges and the SMD components 4 , so that it is possible to mount the SMD components 4 . The plastic material serves to protect the conductor tracks of the leadframe 1 against accidental contacting and also provides corrosion protection for the conductor tracks. Instead of a plastic material, other non-conductive materials suitable for encapsulating the conductor tracks of the leadframe 1 can also be used. Furthermore, the plastic material is deposited on the lead frame 1 by means of a spraying process, wherein the plastic material is ...

Abstract

The invention relates to a method for equipping a contacting element (1), in particular a punched grid with an SMD component (4), comprising the following steps: providing the contacting element (1) with a casing, a connector point (3) being provided in a recess (7) of the casing (5); placing the SMD component (4) on the connector point (3); and heating a thermally conductive element in order to heat the connector point (3) so that the SMD component (4) can be connected to the connector point (4).

Description

technical field [0001] The invention relates to a method for equipping a contacting element with electrical components, and to a contacting element with installed electrical components. Background technique [0002] Contacting elements, such as in particular lead frames or circuit boards, are often used to provide electrical conduction in the module. The lead frame comprises a circuit structure with conductor tracks, which are injection-molded with a plastic material to ensure dimensional stability. Depending on the field of application, it may be necessary to equip the lead frame with electrical components, which must be connected to the conductor rails by soldering for this purpose. In such a lead frame, although local soldering of wiring components or circuit boards can be realized, soldering of SMD components (SMD: Surface Mounted Device (Surface Mounted Device)) to the lead frame cannot be realized. The reason for this is that the temperature stability of the plastic ...
