As some led boards are longer and some are smaller if the borad length exceeds 500mm in length it can’t be handeled by a normal pcb loader so you need to consider a vaccum loader which can hold the long pcb boards.

The basic function of vaccum loader is load the pcb board on the led smtline but as the name suggests its uses vaccum to load the pcb board.

At first the 50 pcb boards stacked in the loader , the loading speed should be set by the digital meter , Now the loader is ready to lift up the board . The loader 4 spindle which vaccum suction fuction which performs the suction and action and load the pcb board in the led smt line now the pcb board in handed over to the solder paste printer for printing of solder paste.

SOLDER PASTE PRINTER

Considering led smt line it requires a long conveyor solder paste printer which can apply the complete solder paste on the led pcb board in general the standard solder paste printer is not capable to handle the long pcb board so if your pcb board is longer that 500mm you should consider a led solder paste printer .

In led solder paste printer the standard width of the pcb board will be 400 mm and the lenght of the pcb board will be 1200 mm which can applied the solder paste on the surface of led pcb board .

Led solder paste printer is the perfert option for led board led pcb boards which can help you to apply the solder paste at once As LED assembly doesn’t required a very high specification solder paste printer.
