Description

Field of technology

The utility model pertains to the section of devices intended for installing connecting leads on radio components, and in particular surface-mounted radio components (resistors, capacitors, inductors, etc.).

State of the art

A method for forming contacts of chip resistors using thick-film technology is known from the state of the art (RU patent No. 2312418 C1 dated 10.12.2007). This method allows for manufacturing contacts of chip resistors, providing increased reliability of intra-contact connections, but does not allow for installing wire leads on surface-mounted radio components.

Also known from the prior art is the information source SU No. 412635, published 25.01.1974, 2 pages, which discloses a cassette for soldering leads to contact pads of radio component blanks. This cassette allows soldering axially oriented leads to radio component blanks using tape solder, but does not allow mounting radially oriented wire leads to surface-mount radio components, and also requires a large number of wire leads (two for each radio component blank) with special contact pads, which complicates their design.

Disclosure of a utility model

The task that the utility model is aimed at solving is to expand the arsenal of means for soldering radially oriented wire leads to contact pads of surface-mounted radio components.

The technical result of the utility model consists in precise positioning of the wire when soldering radial wire leads to contact pads of surface-mounted radio components by fixing the wire in the equipment during soldering, eliminating the displacement of the wire during vibrations or movement of the equipment.

The said technical result is achieved by means of technological equipment for soldering radial leads onto contact pads of surface-mounted radio components, which is characterized by the fact that it includes a heat-resistant dielectric substrate in which longitudinal parallel paired grooves are made, intended for laying wire segments.

The side walls of each groove are equipped with wedge wire retainers during soldering, wherein the wedge retainers located on the first side wall of the groove are offset in the direction of the groove relative to the wedge retainers located on the second side wall of the groove, in addition, all wedge retainers face in the same direction.

Also, on top of each pair of grooves, there are multiple rectangular depressions, which serve to place soldering paste on the wire and to fix the radio components during their installation, while ensuring the orthogonal arrangement of the paired grooves in relation to the long side of the rectangular depressions.

At the same time, the mentioned problem is solved due to the fact that in the proposed device of technological equipment a heat-resistant dielectric substrate is used with longitudinal parallel to each other paired grooves made in it, which serve for laying sections of wire, as well as a plurality of rectangular depressions made on top of each of the pairs of grooves. Rectangular depressions are used for applying high-temperature soldering paste and laying radioelements (surface-mounted capacitors, resistors, inductors, etc.).

A new design element is the wedge clamps located along the paired grooves. These clamps provide reliable fixation of the wire, preventing its displacement during the process of applying soldering paste, laying out radio components and soldering them. This solution eliminates the displacement of the wire during vibrations or movement of equipment, which significantly increases the accuracy and ease of use.

The result, which is provided by the given set of features, is the implementation of the purpose of technological equipment for soldering radial wire leads to contact pads of surface-mounted radioelements with provision of positioning and fixation accuracy. This helps to reduce the technological cycle by reducing labor intensity, increasing accuracy and the possibility of automating the process.

Implementation of a utility model

Fig. 1 shows a device for technological equipment for soldering radial leads to contact pads of surface-mounted radio components, which includes a heat-resistant dielectric substrate 1, in which longitudinal pairs of grooves 2 parallel to each other are structurally implemented, serving for laying sections of wire. A plurality of rectangular depressions 3 are made above each pair of grooves, serving for laying soldering paste on the wire and fixing the radio components during their installation. Additionally, wedge clamps 4 are installed along the pairs of grooves 2.

The interaction with the equipment is carried out as follows: wire segments are placed in longitudinal pairs of grooves 2, which are fixed with wedge clamps 4. Then high-temperature soldering paste is applied over the wire in rectangular recesses 3, and radio components are placed. After installation in the furnace, the wire segments with radio components soldered to them are removed from the equipment. The wire is trimmed, resulting in radio components with radially oriented leads.

The process of applying solder paste, laying and mounting radio components can be automated by placing the tooling with fixed pieces of wire in specialized equipment.

The use of high-temperature soldering paste is due to the need for subsequent soldering of radio components into a printed circuit board at a temperature below the soldering temperature range of the paste.

The advantage of the proposed device is the reduction of the technological cycle, reduction of labor intensity and increase in accuracy due to the use of wedge clamps for reliable fixation of wire when soldering radial leads to contact pads of surface-mounted radio components.
