After connecting multiple boards after soldering, breakage will often damage the circuit or break the electronic parts. This machine cuts through the cutting motion, which can completely reduce stress, prevent cracks in solder joints and breakage of parts, and improve production efficiency and quality. Using the method of upper circular knife and lower flat knife, the board is placed on the lower flat knife. When the switch is stepped on, the upper circular knife moves laterally to the set fixed point, which will cut off the PCB board. The upper circular knife cuts without stripping, and the cut is smooth and seamless. rough edges.
