PURPOSE: A dual lane screen printer is provided to immediately correspond to the size of a printed circuit board and enable horizontal expansion and reduction based on the center of a solder printing part of a conveyor. CONSTITUTION: A dual lane screen printer comprises input standby parts(100,100'), solder printing parts(200,200'), and output standby parts(300,300'). The input standby part comprises a printed circuit board, a body frame(1), and a conveyor formed on an align unit(2). The input standby part receives a printed circuit board by the conveyor and applies solder on the printed circuit board in the shape of patterns. The solder printing part receives the printed circuit board after standby in the input standby part, and the solder printing part applies and discharges solder on the printed circuit board. The solder printing part is horizontally is extended and reduced based on the center thereof to correspond to the size of the printed circuit board. The output standby part receives the printed circuit board from the solder printing part and performs the output standby of the printed circuit board. |
