PCB draft
What material of PCB to use? We don’t think the IMS (Insulated Metal Substrate) choice is the problem. PREMALYS helps you to choose the thermal conductivity of the dielectric. We suggest using our online calculator for preliminary thermal analysis of the LED-heatsink system.
You can request the project, Figure 2.
