This equipment can perform dual-station operations, capable of processing two PCBs simultaneously, greatly improving production efficiency. The spatial layout is compact: the spatial layout of the equipment is very compact, effectively saving production space area, ensuring that the heat sink is precisely attached to the PCB, and it can accommodate PCBs and heat sinks of different sizes. The main working principle is to separate the heat sinks and then attach them individually to designated positions through specific fixtures. The fixture has a double layer in the middle of the equipment, which can effectively perform reflow to ensure the normal operation of the equipment.
