At the same time, the number of components used by these systems is constantly increasing, but the available space is continuously compressed, which also greatly increases the electron density of each system. These systems all require power conversion ICs, and often have multiple power terminals for each subsystem. Because of the very high power density and associated high ambient temperatures, any practical heat sink is too large and impractical, and because of this The space constraints and the operating temperature range requirements make power conversion efficiency very important. LCD screen prices at low output voltages and medium current levels above a few hundred milliamperes make it too impractical to simply use linear voltage regulators to provide these system voltages because too much heat is generated. The result of these restrictions is the use of switching regulators instead of linear regulators. The benefits of switching regulators include increased efficiency and smaller footprints, which are sufficient to compensate for additional design complexity and electromagnetic interference. (EMI) and other issues. Liquid crystal splicing screen LED lighting is replacing traditional incandescent lamps. The use of light emitting diode (LED) lighting in automotive applications is only a vehicle concept. Today, LEDs have been widely used in dashboard backlighting and interior lighting of many automobiles and trucks. And brake lights. In addition, luxury car manufacturers have also gradually increased the application of the latest technology of solid-state LED lighting, through these brighter, smaller, more reliable components to provide interior and exterior lighting, to strengthen the performance and aesthetics of their vehicles. In addition, LEDs can provide lower cost and longer life, providing interior lighting advantages that are significantly superior to incandescent lighting, such as high-pressure gas discharge (HID) and halogen bulbs for headlamps. LCD Panel Trends To use automotive battery-powered LEDs, a DC-to-DC converter is required to accurately regulate the LED current, ensuring consistent illumination intensity and color saturation while protecting the LED. In addition, according to the different uses of LEDs, DC/DC regulators should also be optimized for specific power needs, such as headlights, rear lights, signal lamps, internal situations, or reading lights. One of the challenges is to reduce A battery voltage equal to or higher than the load voltage drives one or more strings of LEDs, while another consideration is to dimming the LEDs effectively with a large dimming ratio while maintaining color at low and high brightness levels. characteristic. The high efficiency operation of the DC/DC driver is a key requirement, especially when driving a high-brightness (HB) LED. Due to the power source that is not converted to scattered light, it will be consumed due to heat generation.
Heavy Copper Pcb
Heavy Copper PCB products are used extensively in power electronic devices and power supply systems. A growing trend in the PCB industry, this unique type of heavy copper PCB features a finished copper weight of more than 4oz (140μm), compared to the 1oz (35μm) or 2oz (0μm) copper weight generally found in those with a Standard PCB copper thickness.
The additional copper PCB thickness enables the board to conduct a higher current, achieve good thermal distribution and implement complex switches in a limited space. Other advantages include increased mechanical strength at connector sites, the ability to create a smaller product size by incorporating multiple weights on the same layer of circuitry and the ability to use exotic materials to their maximum capacity with minimal risk of circuit failure.

Finished Copper PCBs of Superior Quality
BentePCB has a decade of experience in manufacturing and assembling high-performing standard and heavy copper PCB products that help our customers achieve their productivity and profitability goals. We make it a standard operating procedure to have our highly skilled engineers run design for manufactureon every circuit file, and address all questions and concerns before production. This helps to ensure the finished electronic boards meet your performance expectations. Our capable staff includes an in-house quality control department - we guarantee the quality of our Printed Circuit Boards.
(Note: To ensure we can fabricate your thick copper PCB correctly, it is important to take the greater width of traces and spacing between the traces caused by the increased copper weight into consideration.)
