Problems solved by technology

[0004] However, this circuit board connection structure is quite prone to the problem of soldering and fixing components falling off after system verification, and this bad result causes abnormalities such as loose parts
The result of the investigation and analysis is that the adhesion of the welding and fixing components is insufficient, and this bad result is caused by the impact and drop due to excessive force

Abstract

The invention discloses a welding fixing assembly structure which is used for being fixed on a circuit board; an electroplating hole is formed in the circuit board; the welding fixing assembly comprises a rod body, an annular abutting portion, a fixing adhesive and an annular protruding portion. One end of the rod body is used for penetrating through the electroplating hole. The annular abutting portion is arranged on the rod body and is used for abutting against the circuit board, and an annular notch is formed in the bottom surface of the annular abutting portion. The fixing adhesive is usedfor filling between the annular abutting portion and the circuit board and between the circuit board and the rod body. The annular protruding portion is arranged on the rod body and is arranged belowthe annular abutting portion so as to prevent the fixing adhesive from overflowing downwards

Description

technical field [0001] The invention relates to a fixing component structure, especially a welding and fixing component structure which is used for fixing to a plated hole of a circuit board and can effectively increase the pulling force of the welding and fixing component. Background technique [0002] Press, the circuit board is the support body of the electronic components, and the circuit board is covered with lines to connect the electronic components. In order to connect the circuit boards or connect the circuit boards with other electronic components, the circuit boards need to be connected by soldering and fixing components. [0003] This circuit board connection structure usually includes a plating hole on the circuit board, and the welding fixing component passes through the plating hole through the welding post, and there is a circular pad on the welding fixing component. When soldering and fixing the components to connect with the circuit board, the circular pad...
