How does PCB board conduct heat most effectively?

 

PCB (Printed Circuit Board), is a support for electronic components and a carrier for electrical connection of the electronic components. After the electronic equipment adopts PCB, due to the consistency of similar printed boards, manual wiring errors are avoided, and automatic insertion or placement of electronic components, automatic soldering, and automatic detection can be realized, which ensures the quality of electronic equipment

 

As PCB boards continue to develop in the direction of high precision, high density and high reliability, they can continue to shrink in size and cost while achieving improved performance, making PCBs still maintain a strong vitality in the future development of electronic equipment. In the future, it will continue to develop towards high density, high precision, fine aperture, fine wire, fine pitch, high reliability, multi-layer, high-speed transmission, light weight and thinness.


PCB boards are widely used in electronic equipment. The heat generated by electronic equipment during operation will cause the internal temperature to rise rapidly. If the heat is not released in time, the equipment will continue to heat up and the device will fail due to overheating. The reliability of the electronic equipment will decline. Therefore, when there are many heating devices, a large heat sink is generally used. A special heat sink is customized according to the position and height of the heating device on the PCB board, or different height positions are cut out on a large flat plate heat sink. The whole is buckled on the component surface, and contacts with each component for heat dissipation. However, due to the difference in the height of the components during assembly and welding, the heat dissipation effect is not ideal. Generally, a soft thermal conductive silicon

How can LED projectors dissipate heat more effectively? LED (Light Emitting Diode) technology applied in the field of display and lighting has been very mature. With the advancement of technology, this technology has been applied to projectors, and more experienced manufacturers have combined this technology with DLP (Digital Light Processing) The perfect combination of technology makes the LED projector portable and compact, and because of its low power consumption and heat generation, it is widely used in life and personal business. The optical element is the core part of the imaging display in the LED projector. The main components that are easy to generate heat and are affected by the heat are the light bulb and the LCD panel and the nearby optical devices. The projection imaging technology of the projector requires a high light source output. Due to the small size of the device and the concentrated heat, 75% of the projector's power is dissipated in a very small space. If the
