WebFR4 material is a glass-reinforced epoxy laminate commonly used in applications requiring high stiffness and rigidity, such as printed circuit boards (PCBs). It is generally available in two forms: as a solid core laminate or as a multilayer laminate. In either form, it’s a fire-resistant material used to create high-quality PCBs. WebFrom the Engineer’s Toolbox the emissivity coefficient of “copper, polished,” is between 0.023 and 0.052; while the emissivity coefficient of “black enamel paint” is 0.80 – I am using paint as an analog for solder …
WebWhat emissivity settings should I use when looking at PCBs and electronics? If you're looking at a plastic surface, use an emissivity of 0.9—but remember that metal will then be shown as colder in the image. If you're imaging metal, the emissivity should be about 0.15 (depending on the metal and its coating). WebEngineers use this understanding of emissivity and associated radiative heat loss in product design. PCB board design provides a common example of designing heat loss. PCB components includes an expected heat discharge. Product designers manipulate a PCB components’ ability to emit heat by adding specialized coatings and using dark materials.
