How does a PBN heater work? What is the insulation material? What is a PBN heater? PBN material refers to pyrolytic boron nitride material obtained by CVD high-temperature deposition. BN refers to cubic boron nitride, which is obtained by hot pressing. The common thickness of PBN parts is less than or equal to 3mm due to the different acquisition processes. PBN heater refers to a graphite heater formed by depositing a thin layer of graphite on a PBN substrate and forming a graphite band by machining (laser engraving). Finally, the graphite layer is covered with a layer of PBN cover layer (exposed electrode part) to become a complete graphite heater. How many ways are there to process? Generally, there are two ways: 1 st : PBN sheet to make a good groove, and then coated with pyrolytic graphite, add a layer of PBN coating (outside the circuit engraved by the pbn disk, deposition of pyrolytic graphite on the circuit, and then a layer of pbn deposited on th...
