a circuit board

Abstract

The invention discloses a circuit board joint board, which comprises a board body and an abnormal-shaped rib, wherein the board body comprises a first circuit board and a second circuit board; the first circuit board is provided with a first connection position; the second circuit board is provided with a second connection position; the orthographic projection area of the second connection position on the first connection position is greater than the orthographic projection area of the first connection position on the second connection position; and the abnormal-shaped rib comprises a first fixed end and a second fixed end, wherein the first fixed end is fixedly arranged on the first connection position, and the second fixed end is fixedly arranged on the second connection position. The circuit board joint board provided by the invention is provided with the abnormal-shaped rib between the first circuit board and the second circuit board, so that the fixed end of the abnormal-shaped rib correspondingly changes along with the width of the connection position, the position, which can be wide, of the fixed end of the abnormal-shaped rib is as wide as possible, so that connection strength between the two circuit boards is reinforced, and therefore, the circuit board joint board with good connection strength is provided.

Description

technical field [0001] The invention relates to the technical field of circuit board design, in particular to a circuit board assembly. Background technique [0002] The size of the circuit board inside the electronic product is small, and the circuit board is generally used to assemble the board, which is convenient for processing and production. With the rapid development of electronic products, the body of the product is getting thinner and thinner, resulting in the circuit board becoming thinner and thinner. The smaller it is, the number of circuit boards included in the circuit board assembly will increase day by day, and the increase in the number of circuit boards will easily weaken the overall strength of the circuit board assembly. The circuit boards in the prior art are usually fixed on the process side, and the splicing of the circuit board and the process side is usually realized by setting I-shaped connecting bars. Increasingly, the strength of the I-type conne...

[0002] The size of the circuit board inside the electronic product is small, and the circuit board is generally used to assemble the board, which is convenient for processing and production. With the rapid development of electronic products, the body of the product is getting thinner and thinner, resulting in the circuit board becoming thinner and thinner. The smaller the size, the more the number of circuit boards included in the circuit board assembly, and the increase in the number of circuit boards will easily weaken the overall strength of the circuit board assembly

The circuit boards in the prior art are usually fixed on the process side, and the splicing of the circuit board and the process side is usually realized by setting I-shaped connecting bars. Increasingly, the strength of the I-type connecting ribs is weak, which may reduce the strength of the circuit board assembly and affect the patching effect of the combined circuit in the later stage
