Conformal Coating High Power Electronics PCBs | 3 July, 2019

Hello All,

Just wondering if some viewers on the forum have experience with conformal coating of PCBs for high power electronics. High power in this case meaning up to 800v. Any comments with regards differences seen from standard 12/24v electronic PCBs. Are there some coating which are better for high voltages than others. Are things such as delamination & cracking more pronounced at higher voltages. All information appreciated

IPC-HDBK-830A - Guidelines for Design, Selection and Application of Conformal Coatings, 5.4.1 High Voltage (HV)/High Current (HC) will give you a good starting point.

If you don't have 830A, rumor has it that some people can find it here: https://dowservice.custhelp.com/ci/fattach/get/355707/0/filename/IPC-HDBK-830A+Guidelines+for+Design+of+Conformal+Coatings.pdf
