Description

The field of technology.

The claimed invention relates to the fields of electrical engineering and radio engineering, and in particular to products of electronic equipment. The claimed method for manufacturing a composite printed circuit board is mainly implemented in LED lamps.

LED lamps include a composite printed circuit board, which consists of two types of printed circuit boards connected by a jumper. The jumper is preferably in the form of a third type of printed circuit board.

The prior art.

An analogue of the proposed method is a method of assembling a composite printed circuit board (RF patent for utility model No. 119972, IPC Н05К 1/11 Н05К 1/14), in which at least two printed circuit boards are assembled, the ends of which are mechanically and electrically connected to each other, connection performed using a jumper.

The disadvantage of the analogue is that each pair of printed circuit boards is connected separately, which increases the number of operations for the manufacture of printed circuit boards, the installation of electronic components and the assembly of a composite printed circuit board.

Disclosure of the invention.

The technical result provided by the claimed invention is to reduce the number of operations for the manufacture of composite printed circuit boards.

SUMMARY OF THE INVENTION

A method of manufacturing a composite printed circuit board includes a mechanical and electrical connection between a printed circuit board of the first type with a printed circuit board of the second type. The connection is performed using a jumper made in the form of a printed circuit board of the third type. The method is characterized in that they use standardized blocks of printed circuit boards, each of which is composed of the same number of printed circuit boards of the first and second type. The blocks are interconnected in pairs, and first one block of the pair is turned 180 degrees relative to the second block of the pair and the said blocks are joined by the ends. Each printed circuit board of the first type of one block pair is joined with a printed circuit board of the second type of another block pair. Jumpers are placed over the joint line along the entire length, which are then fixed to the printed circuit boards of the first and second blocks of the pair. The resulting product is divided into composite printed circuit boards.

At the joints of the printed circuit boards in the block, it is preferable to carry out fault lines. The jumpers are predominantly composed in a block and are divided in it by fault lines. In this case, when the jumper block is superimposed on the printed circuit board blocks, it is advisable to combine the fault lines of the jumper block with the fault lines of the printed circuit boards. The aforementioned product obtained is preferably separated along the fault lines away from the bridge.

The implementation of the invention.

In the method of manufacturing a composite printed circuit board, pre-fabricated unified blocks of printed circuit boards (3) (figure 1, 2). Each block (3) contains printed circuit boards of the first (1) and second type (2). The printed circuit boards of the first (1) and second (2) type are preferably made of the same width. In each block (3), the number of printed circuit boards of the first type (1) is equal to the number of printed circuit boards of the second type (2). Printed circuit boards (1, 2) in the block can be grouped by type of printed circuit boards (figure 1), or alternate between each other (figure 2). At the joints of the printed circuit boards in each block (3), fault lines (4) are made. Unified blocks of printed circuit boards (3) after manufacturing are sent to the machine for mounting electronic components, mainly LEDs. The manufacture of printed circuit boards in unified blocks (3) reduces the number of operations:

- in the manufacture of printed circuit boards (one block (3) is made according to one template instead of two boards according to two templates);

- during the installation of electronic components (installation of the unit (3) is carried out in one cycle instead of installing two boards in two cycles). Machines are programmed once for the entire work cycle.

After the manufacture and installation of unified blocks of printed circuit boards (3) they are connected together in pairs (Fig 3). Moreover, first one block of the pair is rotated 180 degrees relative to the second block of the pair (3), and the two blocks (3) are joined by the ends. In this case, each printed circuit board of the first type (1) of one block pair is joined with the printed circuit board of the second type (2) of another block pair. After that, jumpers (5) (Fig. 4) are applied to the joint line along the entire length, which are then fixed to the printed circuit boards of the first and second blocks (3) of the pair. Each jumper (5) preferably has the form of a printed circuit board of the third type (Fig. 5) and is a rigid insulating base, mainly of PCB, on the surface of which electric conductors (6) are made. The jumpers (5) are preferably composed in a block and separated therein by fault lines (4). The distance between the fault lines (4) in the block of jumpers (5) is equal to the distance between the fault lines (4) in the block of printed circuit boards (3). When the jumper block (5) is superimposed on the printed circuit boards (3), the fault lines (4) of the jumper block (5) are combined with the fault lines (4) of the printed circuit boards (3) (Fig. 4). When fixing jumpers (5) to the printed circuit boards of the first (3) and second blocks (3) pairs, the electrical conductors (6) of the jumpers are electrically connected to the output pads (7) of the printed circuit boards of these blocks (3) pairs of solder.

Blocks (3), fixed by jumpers (5), are a series of interconnected composite printed circuit boards (Fig.6). The composite printed circuit board from the resulting product is separated along the fault line to the side of the jumper.

The use of a composite printed circuit board is to install it in the nodes of electronic equipment or in the cases of LED lamps.

Thus, from the foregoing, it follows that in the claimed method of assembling printed circuit modules, the claimed technical result: “reducing the number of operations for the manufacture of composite printed circuit boards” is achieved due to the fact that the method uses unified blocks of printed circuit boards (3), each of which is composed from the same number of printed circuit boards of the first (1) and second type (2), while the blocks (3) are connected in pairs (Fig. 3), and first one block of the pair (3) is rotated 180 degrees relative to the second block of the pair and st forging said blocks (3) ends, wherein each circuit board of the first type (1) of one block (3) couples the junction with the printed circuit board of the second type (2) of the other unit of the pair (3). Then, jumpers (5) (Fig. 4) are applied to the joint line along the entire length, which are then fixed to the printed circuit boards of the first (3) and second blocks of the pair (3), after which the resulting product is divided into composite printed circuit boards (Fig. 6) .

Industrial applicability.

The author of the invention tested the claimed method, which confirmed the achievement of the technical result.

The inventive method of manufacturing a composite printed circuit board is implemented using industrially produced devices and materials, can be carried out at any enterprise in the electronics industry and will be widely used in electrical and radio engineering, namely in the manufacture and assembly of LED lamps.
