Printed circuit board (PCB) press，the utility model is characterized in that: a groove is arranged around the bottom edge of the hot pressing plate, an asbestos board which is flush with the bottom edge is fixed on the groove, an inverted L-shaped pipe is arranged at the side of the hot pressing plate, the outer end of the inverted L-shaped pipe is connected with the vacuum pump, and the bottom end is aligned with the connecting space formed around the inner edge of the PCB placement box; In addition, a heat-resistant rubber is arranged above the four sides of the placing box and is opposite to the asbestos board; The cold pressing plate is provided with transverse cross parallel heat dissipation through holes between the circulation loops, and is provided with longitudinal heat dissipation ports on both sides; With the combination of the above components, the hot pressed plate has the function of vacuumizing when pressing the printed circuit board, while the cold pressed plate uses air to send into the circulation circuit for cooling and heat dissipation.  

The printed circuit board pressing machine comprises: a car for conveying the hot pressing mechanism and cold pressing mechanism of the stacked printed circuit boards; The utility model relates to a hot pressing mechanism, which uses a hot oil device arranged outdoors to heat through the hot pressing plate circulation circuit of each layer; A cold pressing mechanism is provided with several layers of cold pressing plates, and a circulating circuit is arranged in each cold pressing plate; The utility model is characterized in that: a groove is arranged around the bottom edge of the hot pressing plate, and an asbestos board which is cut flush with the bottom edge is fixed on the groove. An inverted L-shaped pipe is arranged at the side of the hot pressing plate, the outer end of the inverted L-shaped pipe is connected with the vacuum pump, and the bottom end is aligned with the connecting space formed around the inner edge of the PCB placement box; A heat-resistant rubber relative to the asbestos board is arranged above the four sides of the placing box; The circulation loops of the cold pressing plate are provided with transverse cross parallel heat dissipation through holes, and the two sides are provided with longitudinal heat dissipation ports.
