While meeting this demand, effective heat dissipation has become crucial. In the application of traditional LED heat sink substrates, Metal Core PCBs (MCPCBs) and ceramic heat sink substrates play a key role. However, there are some differences between them, particularly in terms of application scope and performance. This article will discuss these two types of heat sink substrates in depth and compare their applications in the COB (Chip on Board) process.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" width=\"800\" height=\"509\" class=\"alignnone size-large wp-image-9375\" src=\"https:\/\/www.jingpengpcb.com\/wp-content\/uploads\/2024\/10\/metal-substrate.jpg\" alt=\"Metal Substrate\" srcset=\"https:\/\/www.jingpengpcb.com\/wp-content\/uploads\/2024\/10\/metal-substrate.jpg 800w, https:\/\/www.jingpengpcb.com\/wp-content\/uploads\/2024\/10\/metal-substrate-300x191.jpg 300w, https:\/\/www.jingpengpcb.com\/wp-content\/uploads\/2024\/10\/metal-substrate-768x489.jpg 768w\" sizes=\"auto, (max-width: 800px) 100vw, 800px\" \/><\/p>\n<h2>Advanced: Where Is the Thermal Resistance of a Heat Sink Substrate?<\/h2>\n<p>When evaluating a heat spreader, one cannot rely solely on the thermal conductivity; instead, one must consider the thermal resistance of the entire heat transfer path.

The key difference from FR4 is that MCPCB utilizes metal as its core technology, employing aluminum or copper as the substrate, with a layer of copper foil or copper sheet attached to the substrate to form the circuit traces. This structure is designed to improve heat dissipation and address issues such as poor thermal conductivity.<\/p>\n<h3>Advantages of MCPCB<\/h3>\n<p>Aluminum inherently possesses good ductility and thermal conductivity; when combined with copper\u2019s high thermal conductivity, it should theoretically provide excellent heat conduction and heat dissipation. However, since aluminum is a conductor itself, in order to prevent the copper circuits from<a href=\"\/en\/metal-substrate\/\">Aluminum Substrate<\/a>To ensure electrical conductivity between components, MCPCBs typically use polymeric materials as the insulating layer. However, the thermal conductivity of this insulating layer (polymer) is only 0.2<del>0.5 W\/mK, and there are issues with heat resistance. Therefore, although aluminum and copper are excellent conductors of heat, the addition of polymer materials creates thermal resistance, which significantly reduces the substrate\u2019s overall thermal conductivity, resulting in an MCPCB thermal conductivity of only 1 W\/mK.<\/del>2.2 W\/mK. In addition, MCPCBs face issues related to metal expansion, which can lead to instability in the voltage withstand characteristics of LED products.<\/p>\n<h2>Advanced: A Comparison of Four Types of
