  • Printed circuit board backup plate and the preparation method thereof
    Patent number: 9572262
    Abstract: A PCB backup plate preparation method comprises: lubricating and radiating resin is coated onto both surfaces of the wood fiberboard and a resin layer forms, before it is totally dried out, wood pulp paper is bonded to its surfaces, then, the surface of the wood pulp paper is coated with unsaturated polyester resin and forms a resin layer, and the PCB backup plate is prepared; the lubricating and radiating resin is prepared by a 95 weight portion of principal component, composed by two or more of polyethylene oxide, polyethylene glycol, glycerol, vinyl acetate and polyvinyl alcohol, and a 5 portion of nonionic surfactant. The lubricating and radiating resin brings the PCB good lubricating and radiating capabilities, therefore increases the drilling hole accuracy when starts to drill, improves the hole wall quality and lowers the drill pin temperature.
