The solder belt entering flux sheet and the production manner, and uses this solder belt entering flux sheet the soldered manner

摘要

PURPOSE:To uniformize soldering quality by filling flux between plural parallel solder wires and subsequently, sticking pieces of released paper thereto to form a flux sheet and soldering electronic parts via the flux sheet. CONSTITUTION:The plural solder wires 1 are arranged in parallel on the bottom of a vessel 3 and the flux 7 is filled and solidified on the vessel bottom 4 and further, the pieces of released paper, 8 are stuck to the surfaces to form the flux sheet 2. One surface of the flux sheet 2a containing the solder wires whose peeling paper 8 is removed is then arranged corresponding to lead wires of the electronic parts. The other surface is adhered on a printed board and the flux sheet 2a is heated to perform soldering. Since the solder wires arranged in parallel at prescribed intervals are arranged corresponding to the lead wires 13 to perform soldering, excess and deficiency of the solder quantity and the occurrence of bridge are prevented. Accordingly, the soldering quality is uniformized.
