A flame retardant pcb board

Abstract

The invention discloses a flame-retardant PCB board, which comprises a mounting plate, a mounting hole, a silica gel heat conducting frame, a heat dissipation hole, a semiconductor refrigeration sheet, a heat dissipation copper pipe, a connecting copper pipe, a heat conducting plate, an insulating plate, a fixing block, a micro fan, a set Air bucket, fireproof frame, heat conduction inner core, insulating frame, inner insulating layer, flame retardant layer, anti-aging layer, power layer, waterproof layer, grounding layer, chip, copper foil layer, outer insulating layer and temperature sensing IC. The invention has a reasonable structure, the real-time temperature of the chip can be detected in time through the temperature sensing IC, and the work of the micro fan and the semiconductor refrigeration chip is controlled according to the temperature, and the bottom of the PCB board is provided with support insulation and heat transfer through the insulating plate and the heat conducting plate. The micro fan drives the air from the air collecting bucket to the silicone heat conduction frame, so as to quickly cool down the heat dissipation copper pipe and take away the heat generated by the semiconductor refrigeration sheet when it is working. Effect.

Description

technical field [0001] The invention relates to a flame-retardant PCB board, in particular to a flame-retardant PCB board, and belongs to the technical field of PCB board applications. Background technique [0002] Printed circuit boards, also known as printed circuit boards, are providers of electrical connections for electronic components. According to the number of layers of circuit boards, they can be divided into single-sided, double-sided, four-layer, six-layer and other multi-layer circuit boards. The printed circuit board has developed from a single layer to a double-sided board, a multi-layer board and a flexible board, and is constantly developing in the direction of high precision, high density and high reliability, continuously reducing the volume, reducing the cost, and improving the performance, making the printed circuit board In the development of electronic products in the future, it still maintains a strong vitality. The future development trend of printed ...

Problems solved by technology

[0003] At present, as a kind of integrated circuit board, PCB board is developing more and more rapidly. Among them, multi-layer PCB board can increase the wiring area, which has its unique advantages. The previous multi-layer PCB board has a single structure and function, and poor waterproof and flame retardancy. , there is no active heat dissipation device, in some more complex working environments, ordinary PCB boards are difficult to adapt to, resulting in a low service life of the PCB board, and the existing PCB board insulation effect is poor, and the PCB board is easily affected by the surrounding electrical appliances Component influence
