In recent years, low carbon, energy saving, and environmental protection have attracted more and more attention. As an LED lighting that has always been optimistic and environmentally friendly, it has gradually become the trend of energy-saving lighting.
At present, all countries in the world attach great importance to the development and utilization of LEDs. NEC has developed and marketed a new type of LED bulb, which is similar in shape to the current incandescent bulbs and is rapidly spreading to ordinary households. AT&S, the world's leading manufacturer of printed circuit boards, is actively developing printed circuit boards for LEDs and intends to use this type of printed circuit board as a pillar of the future. Matsushita Electric has developed CEM-3 CCL for high heat dissipation performance for LEDs 2 to 3 years ago and has been shown on CPCASHOW.
The Korean government, which is "becoming the world's top three LED industry powerhouses," is also actively implementing plans to replace street lights with LED lighting. It is understood that KPCA, the Korean electronic circuit industry association, is the first in the world to standardize LED printed circuit boards, and set up a working group for printed circuit boards for LEDs. It is taking time to develop this standard and promote the standardization of printed circuit boards for LEDs. jobs.
The Japan Electronic Circuit Industry Association (JPCA) has released the "JPCA-TMC-LED01S High-brightness LED Electronic Circuit Board Standard" and the "JPCA-TMC-LED02T High-Brightness LED Electronic Circuit Board Test Method" developed by the Association this year.
However, LED printed circuit boards are not what some of us think are only metal-based (aluminum-based) copper clad PCBs, but according to different uses, some use general FR-4, FR-5, CEM-3 Flexible polyimide plates, some use resin substrates with heat-dissipating vias, high-heat-transfer resin substrates, and some use metal-based substrates, metal core substrates, and ceramic substrates. While we are talking about the adjustment of product structure, LED will inevitably become a very important industry in China because of its energy-saving characteristics. And its wide-ranging use and huge market prospects will have a huge impact on China's energy conservation and consumption reduction, and it will also provide a huge market for the printed circuit industry.
