1. a kind of processing method for improving polytetrafluoroethylene (PTFE) printed circuit sheet metal forming burr, which is characterized in that the described method includes:

  • Polytetrafluoroethylene (PTFE) printed circuit board, the first phenolic aldehyde backing plate, the second phenolic aldehyde backing plate and several brown paper are taken, it is spare;

    It is describedInclude molding location hole on polytetrafluoroethylene (PTFE) printed circuit board;

    According to the molding location hole of the polytetrafluoroethylene (PTFE) printed circuit board, by gong machine to the first phenolic aldehyde backing plate, secondPhenolic aldehyde backing plate and several brown paper drill;

    According to the drilling, the first phenolic aldehyde backing plate, polytetrafluoroethylene (PTFE) printed circuit board, the second phenolic aldehyde backing plate are successively packed intoIt is implanted into as required on the bakelite plate of pin in advance;

    The first phenolic aldehyde backing plate, polytetrafluoroethylene (PTFE) printed circuit board, the second phenolic aldehydeIt is arranged between backing plate by brown paper interval;

    Milling cutter, which is clamped, by gong machine main shaft cuts the polytetrafluoroethylene (PTFE) printed circuit board, the first phenolic aldehyde backing plate, the second phenolic aldehyde padPlate and several brown paper, process velocity are set as 0.2m/min~0.4m/min.
