Circuit board flattening device
Technical Field
The invention relates to the technical field of flattening devices, in particular to a circuit board flattening device.
Background
In order to prolong the service life of the PCB, most enterprises generally plate a thin gold plating layer on the surface of the PCB, and the PCB needs to be leveled before the gold plating treatment, so that ions in the plating solution can be attached to the surface of the PCB efficiently.
The common method for flattening the circuit board is to flatten the circuit board by using a compression roller, wherein the compression roller flattening refers to a method for flattening the circuit board by using a power mechanism to provide power to drive a connecting frame to move back and forth so as to enable the compression roller arranged on the connecting frame to move back and forth on the circuit board to be flattened.
The circuit board need be fixed at ordinary times to the pinch roller, prevent that the circuit board from sliding, the efficiency that the influence was flattened, it is too firm that the device that is common to the circuit board is fixed with the circuit board, and the pressure at the horizontal direction passes through the circuit board and can act on fixing device when the pinch roller flattens, the effect of power is mutual, and then cause the damage to the edge of circuit board and fixing device contact, bring unnecessary loss, simultaneously, common circuit board thickness is between 0.3 millimeter-2.3 millimeter on the market, but traditional circuit board flattening device can only flatten the circuit board of appointed thickness, can not flatten the circuit board of different thickness, for this, we propose a circuit board flattening device.
