A hot press machine is a device that heats two pre-fluxed and tinned parts to a temperature sufficient to melt and flow the solder, cure it, and form a permanent electro-mechanical connection between the part and the solder. The heating up speed is selectable according to different products. The titanium indenter ensures an even temperature, fast heat-up and an exceptionally long service life. The pressure head is specially designed to be horizontally adjustable to ensure even pressure on the component. The temperature is numerically controlled for clear precision. Digital pressure gauge with preset pressure range.
Adopt advanced electronic new product control, through the adjustment can be automatically completed the processing process of table feeding, table raising, heating, vacuum, film pressure, film release and table lowering. It is mainly powered by oil pressure and compressed air, so there should be enough air pressure and air volume. The frame is made up of whole processing with steel plate, and the whole structure is reasonable, and the two working tables can be used in cycle or separately. The vacuum can be adjusted to low pressure first, then high pressure suction coating, the film pressure pressure can reach 0.4MPa, through the adjustment, the product can achieve the ideal effect.

The machine is used for PC, PVC, PET and other membrane switch concave and convex surface forming, instead of the traditional cold stamping, a molding without scrap, by domestic and foreign customers unanimously praised, also can be used for a variety of cell phones, remote control keys, plastic products whole cut and slitting; digital products or computer LCD protective film cutting, a variety of stickers, trademarks and other precision cutting, cutting half, etc.; also can be used for other metal (non-metal) hot press machineing molding, such as soft It can also be used for other metal (non-metal) hot press machine molding, such as flexible circuit board pressing, computer heat dissipation copper tube, various non-metal welding, etc. The hot press machine part of the switch can be used for other assembly and stamping purposes.
Pulse heating principle, due to the special design of the surface of the welding head, the resistance of the welding surface is very small, and the current will pass through the section with the smallest resistance. By constantly changing the voltage and adjusting the current level, the weld head is rapidly heated through. A 2000W transformer is used to generate a high current at a low voltage, which rapidly heats up the weld head. The greater the pulse ratio, the greater the current output and the faster the weld head heats up.
Thermostatic heat press, pulse heat press, duplex heat press, dual head pulse heat press, bench top heat press, etc. According to the different medium of hot press machine, it can be classified as tin solder, ACF (anisotropic conductive tape), ACP (anisotropic conductive glue), TBF (hot melt adhesive film). It is suitable for the connection of FPC (flexible circuit board), HSC (zebra paper), TAB with LCD and PCB. As the Pitch of PCB or FPC in consumer electronics tends to be smaller, the traditional soldering process has been difficult to meet the requirements of very fine thermal pressure. the ACF process has been gradually applied by cell phone designers.
In addition, positive pressure is added on the basis of negative pressure with special glue, for the processing of PVC series, the line shape in place and pasting force is incomparable to the negative pressure equipment, due to its high pressure, low temperature and short film pressure time, it solves the problem of deformation when processing workpieces (especially large area workpieces) by negative pressure equipment, so that the deformation of workpieces is greatly reduced.
