Abstract

The invention discloses a waterproof PCB. The PCB comprises a circuit main board and more than one electronic component installed on the circuit main board. More than one bonding pad device is embedded in the circuit main board; each bonding pad device comprises a bonding pad element and a mounting part, wherein the bonding pad element is embedded into the circuit mainboard and is connected with the circuit mainboard for electric conduction; a flexible connecting part is arranged at one end of the mounting part; one end of the flexible connection part is connected with the installation part, the other end of the flexible connection part is connected with the bonding pad element for electric conduction, the installation parts between two adjacent bonding pads are in butt joint with each other and form an installation protection cavity in the middle, the electronic component is assembled in the installation protection cavity, and pins of the electronic component are respectively welded with the installation parts for electric conduction. The electronic components on the circuit board have very good torsion resistance and very good waterproof capacity, the pins and the welding positions are well protected, and the service life of the circuit board is prolonged.

Description

technical field

[0001] The invention relates to a circuit board, in particular to a waterproof PCB circuit board. Background technique

[0002] PCB (Printed Circuit Board), the Chinese name is printed circuit board, also known as printed circuit board, is an important electronic component, a support for electronic components, and a carrier for electrical connections of electronic components. Because it is made using electronic printing, it is called a "printed" circuit board.

[0003] There are a large number of pads on the circuit board, and the pins of the electronic components are soldered to the pads respectively. In later use, if the water resistance of the electronic equipment becomes poor and enters, the incoming water will directly contact the pads and pins. , resulting in a short circuit. In addition, it is inconvenient to adjust the position of the electronic components installed on the circuit board. After a long period of use, if the electronic components are s...
