Composite circuit board

Abstract

The invention discloses a composite circuit board which comprises a circuit mainboard. The four corners of the circuit mainboard are each pluggably provided with a metal fixing block, a connecting column is welded between every two adjacent metal fixing blocks, one or more rotating shaft sleeves are evenly distributed on the connecting column on one side, one ends of the rotating shaft sleeves areeach provided with a component fixing belt, each component fixing belt comprises a head end connecting piece, a middle connecting piece and a tail end connecting piece, wherein the relative faces ofthe head end connecting piece, the middle connecting piece and the tail end connecting piece are each provided with one clamping groove, a connecting piece is installed between every two adjacent connecting pieces, and the two ends of the connecting pieces are inserted into the clamping grooves in the connecting pieces. All electronic components and the circuit mainboard are in contact connection,the electronic components can be replaced freely, the service life of the circuit mainboard can be prolonged, assembling and disassembling are convenient, the problem of electronic component pin breakage is lowered, the impact resistance and the cooling performance of the mainboard are improved, and the circuit board is small in size and convenient to adjust and use.

Description

technical field [0001] The invention relates to a circuit board, in particular to a composite circuit board. Background technique [0002] The circuit board is the main core component of various electronic products. The circuit board roughly includes the main board and the electronic components welded on the main board. The electronic components are introduced and welded on the designated position of the circuit board through soldering. Because the pins are directly welded to the circuit board, there are many problems. First, after the electronic components are welded, it is difficult to remove them. After removal, the solder remains on the main board. If you want to replace the components, you must It is very inconvenient and time-consuming to remove the solder on the main board first; second, the introduction of soldering through soldering is easy to fall off, resulting in the need to disassemble and re-solder later, and the service life of each electronic component is sho...

Because the pins are directly welded to the circuit board, there are many problems. First, after the electronic components are welded, it is difficult to remove them. After removal, the solder remains on the main board. If you want to replace the components, you must It is very inconvenient and time-consuming to remove the solder on the main board first; second, the introduction of soldering through soldering is easy to fall off, resulting in the need to disassemble and re-solder later, and the service life of each electronic component is short; third, the electronic components are directly Welded on the main board, when it is impacted, it directly impacts on the electronic components, causing damage to the electronic components, introducing fractures, and poor cushioning resistance; fourth, the bottom of the electronic components will generate a lot of heat, especially the center of the main board. Poor performance reduces the lifespan of the motherboard
