Novel Thermal Protection System for Powered Circuit Boards Including Fuses

Abstract

A coated electronic device that is fire resistant includes an electronic component and an intumescent layer disposed over the electronic component. The intumescent layer includes sodium silicate having formula Na2SiO3, pentaerythitol, a resin that is cross-linked by melamine, boron nitride particles, and triammonium phosphate.

Description

technical field [0001] In at least one aspect, the present invention relates to intumescent coatings for electronic components, and more particularly to intumescent coatings for circuit boards and fuses that may overheat and cause fires. Background technique [0002] Many electronic devices experience overheating which poses a certain risk of fire. For example, a short circuit in a device can generate a lot of heat. Inadvertent contact between an electronic component and water from a coolant leak or moisture buildup can cause this short circuit to occur. In addition, failed components may cause high electrical potentials, which can also cause fire or thermal runaway. [0003] Prior art approaches attempt to address fire risks in electronic devices in various ways. For example, electronics may be enclosed in a fire resistant enclosure. While such approaches work reasonably well, very few of the prior art approaches that address fire resistance provide a multifaceted solut...
