Problems solved by technology

[0007] This is because the absence of lead in the metal alloy, as a trade-off, brings several drawbacks, including significantly reducing the wettability of the alloy, making it difficult for the solder to "deposit" over the entire available surface between the contact and the board
Thus, an imperfect soldering of the components on the board is obtained, which can later lead to cracking of the electronic board and its components or failure of the system motors, and finally a particularly expensive repair or replacement operation of the board-component assembly

Embodiment Construction

[0026] exist figure 1 In the exemplary embodiment shown, the assembly device 1 of the invention is defined by an intermediate independent module 2 that fulfills the duties of an interface, as will be discussed later with respect to image 3 It can be seen that said intermediate independent module 2 is located between the printed circuit board or card C and the electrical components CC, B which are to be connected at specific positions on the board by means of the device 1 . It is thus understood that this module is different from a board or a printed circuit on which it is added by means of a reflow soldering process.

[0027] To this end, the intermediate module 2 includes metal linking members 3 that provide a path for the current between a specific location and the electrical components to be installed, and insulating supports 4 that connect metal The link members 3 are kept together and separated from each other in this way. In this embodiment, the module 2 has a substan...

Abstract

The invention relates to a device for assembling electric components on a printed circuit board, wherein said device is provided in the form of an intermediate module (2) arranged between said board (C), which is coated with a metal solder layer (CM), and said components (CC, B,...) which are to be mounted thereon, and wherein said intermediate module (2) includes: a plurality of metal linking members (3), one side of which is mounted on said board (C) by means of remelting the solder metal layer (CM), and the other side of which, remote from the board, is suitable for receiving said components; and an insulating bracket (4) combining said metal linking members (3) separately from one another.

Description

technical field [0001] The present invention relates to a device for assembling electrical components or the like on printed circuit boards or cards, such as, in a particular but not exclusive application, intended for a heating, ventilation and air conditioning system for motor vehicles A controller of the motors of the system, and said system equipped with such assembly means. Background technique [0002] In order to be able to adjust at will the rate of flow of air brought into the interior of a motor vehicle, the usual heating, ventilation and air conditioning (HVAC) system, in addition to heat exchangers to obtain the desired effect in terms of heating, cooling, etc., also includes electric motors, blowers The impeller is mounted on the shaft of an electric motor and is denoted by the term "motor-driven fan", the speed of its rotation, selected by the driver via a specific button on the dashboard, is controlled by a "controller", which is an electronic printed circuit ...
