Insulated Metal Substrate PCBs or “IMS” PCBs offer heat sink solutions for thermal applications. Depending on the design requirements of your PCB, IMS may be a more effective solution than embedded heat sinks. IMS boards are commonly used in the automotive and lighting industries. They aid in keeping components cool/extending component life, thus increasing product life while enhancing reliability.
In addition to its thermal advantages, insulated metal substrate PCBs are a great solution for small devices where space is limited. These PCBs don’t require things like cooling fans and other components which helps save space on the circuit board.
Depending on your device’s needs, insulated metal substrate PCBs may be the right solution for you. Use the buttons below to request a quote or learn more about your PCB options.
