It not only realizes electrical connection but also plays a supporting role. As the core component of electronic products, it is widely used in various electronic devices. In the field of LED lighting, PCB light board provides support and power for LED lamp beads, ensuring their stable operation in scenes such as home, commercial and automotive lighting. PCB with LED is often used to manufacture electronic products such as indicator lights, lighting equipment and display screens. The LED lamp beads on these PCBs are usually precisely soldered by SMT (surface mount technology).<\/p>\n\n\n\n<div class=\"wp-block-cover\" style=\"min-height:346px;aspect-ratio:unset;\"><span aria-hidden=\"true\" class=\"wp-block-cover__background has-background-dim\"><\/span><img decoding=\"async\" class=\"wp-block-cover__image-background wp-image-1991\" alt=\"What Is led light pcb?\" src=\"https:\/\/www.bestpcbs.com\/blog\/wp-content\/uploads\/2024\/07\/16.jpg\" data-object-fit=\"cover\"\/><div class=\"wp-block-cover__inner-container is-layout-flow wp-block-cover-is-layout-flow\">\n<p class=\"has-text-align-center has-large-font-size\"><strong>led light pcb<\/strong><\/p>\n<\/div><\/div>\n\n\n\n<p>LED PCB light board leads the development of the lighting industry with its innovative design, high efficiency and flexibility, bringing a more intelligent and comfortable lighting experience to our lives.

The traditional FR4 printed circuit board (PCB) has been unable to meet the heat dissipation requirements due to its low thermal conductivity (only 0.36W\/m.K). In order to solve this problem, the metal core printed circuit board (MCPCB) was proposed. It attaches the original printed circuit board to a metal with better thermal conductivity (such as aluminum and copper) to enhance the heat dissipation effect. The thermal conductivity efficiency of MCPCB is higher than that of traditional FR4 PCB, reaching 1W\/m.K to 2.2W\/m.K, which effectively improves the heat dissipation performance of LED PCB.<\/p>\n\n\n\n<p>In addition, the use of MCPCB can also reduce the number of LEDs required to generate lighting, making it an ideal choice for street lights, automotive LED applications, and backlight unit applications. The use of metal substrates has practical advantages in heat dissipation, thermal conductivity, reliability, and electrical insulation, especially in harsh environments, and can also achieve reliable operation of LEDs. For example, using a metal substrate can reduce the LED junction temperature by 20-30\u00b0C, improve light output and enhance the overall performance of the product, ensure consistent UV light generation, and expand the possibilities of UV applications in various industries.<\/p>\n\n\n\n<div class=\"wp-block-cover\" style=\"min-height:343px;aspect-ratio:unset;\"><span aria-hidden=\"true\" class=\"wp-block-cover__background has-background-dim\"><\/span><img decoding=\"async\" class=\"wp-block-cover__image-background wp-image-2064\" alt=\"Why use mcpcb for led light pcb\" src=\"https:\/\/www.bestpcbs.com\/blog\/wp-content\/uploads\/2024\/08\/18.jpg\" data-object-fit=\"cover\"\/><div class=\"wp-block-cover__inner-container is-layout-flow wp-block-cover-is-layout-flow\">\n<p class=\"has-text-align-center has-large-font-size\"><strong><mark style=\"background-color:rgba(0, 0, 0, 0)\" class=\"has-inline-color has-luminous-vivid-orange-color\">Why use mcpcb for led light pcb<\/mark><\/strong><\/p>\n<\/div><\/div>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Advantages_of_led_light_pcb\"><\/span>Advantages of led light pcb?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p><strong><mark style=\"background-color:rgba(0, 0, 0, 0)\" class=\"has-inline-color has-luminous-vivid-orange-color\">High thermal conductivity: <\/mark><\/strong>LED PCB, especially aluminum substrate, uses aluminum alloy material with high thermal conductivity, which can effectively conduct away the heat generated by LED, maintain the stability of LED operation and extend the service life.

The heat generated by the device during operation is quickly transferred to the metal base layer through the insulating layer, and then the metal base layer transfers the heat to achieve heat dissipation of the device. Compared with the traditional FR-4, the aluminum substrate can reduce the thermal resistance to the minimum, making the aluminum substrate have excellent thermal conductivity; compared with the thick film ceramic circuit, its mechanical properties are extremely good. In the circuit design scheme, the heat diffusion is handled very effectively, thereby reducing the module operating temperature, extending the service life, and improving the power density and reliability; reducing the assembly of the heat sink and other hardware (including thermal interface materials), reducing the product volume, and reducing the hardware and assembly costs; combining the power circuit and the control circuit<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"How_to_make_a_LED_light_circuit_board\"><\/span>How to make a LED light circuit board?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<ol class=\"wp-block-list\">\n<li>Cutting<\/li>\n\n\n\n<li>Cutting process Picking materials &#8211; cutting<\/li>\n\n\n\n<li>The purpose of cutting<br>Cut the large-sized incoming materials into the size required for production<\/li>\n\n\n\n<li>Precautions for cutting<br><mark style=\"background-color:#abb8c3\" class=\"has-inline-color\">\u2460 Check the size of the first piece of material<br>\u2461 Pay attention to the scratches on the aluminum surface and the copper surface<br>\u2462 Pay attention to the delamination and flash of the board edge<\/mark><\/li>\n\n\n\n<li>Drilling<\/li>\n\n\n\n<li>Drilling process<br>Pinning &#8211; drilling &#8211; board inspection<\/li>\n\n\n\n<li>The purpose of drilling<br>Positioning and drilling holes in the board to assist the subsequent production process and customer assembly<\/li>\n\n\n\n<li>Precautions for drilling<br>\u2460 Check the number of holes and the size of the holes<br>\u2461 Avoid scratches on the board<br>\u2462 Check the flash of the aluminum surface and the hole position deviation<br>\u2463 Check and replace the drill bit in time<br>\u2464 Drilling is divided into two stages, one drilling: drilling holes after cutting for peripheral tool holes<br>Second drilling: tool holes in the unit after solder mask<\/li>\n\n\n\n<li>Dry\/wet film imaging<\/li>\n\n\n\n<li>Dry\/wet film imaging process<br>Grinding board &#8211; film pasting &#8211; exposure &#8211; development<\/li>\n\n\n\n<li>Purpose of dry\/wet film imaging<br>To present the part required for making circuits on the board<\/li>\n\n\n\n<li>Precautions for dry\/wet film imaging<br>\u2460 Check whether the circuit is open after development<br>\u2461 Whether the development alignment is biased to prevent the generation of dry film fragments<br>\u2462 Pay attention to the circuit defects caused by scratches on the board<br>\u2463 No air should remain during exposure to prevent poor exposure<br>\u2464 After exposure, it should be still for more than 15 minutes before development<br>IV.
