Title: Reflow device
Inventor: NISHI TOSHIO
IPC: B23K101/42
Filed: 1991-02-14
Abstract: PURPOSE:To prevent temperature from abnormally rising and to satisfactorily cure UV resin by circulating cooling gas into a lamp room and radiating UV light beam through UV transmitting material. CONSTITUTION:When a substrate 5 transferred from a carry-in conveyor 7 to a conveyor 4 is irradiated with UV light, the UV resin to temporarily adhere an electronic parts 6 to the substrate 5 is hardened. Then, the substrate 5 is heated while it is transferred by the conveyor 4 and the solder is melted. Then, the solder is cooled and solidified while the substrate 4 is transferred by the conveyor 4 and a carry-out conveyor 8 and the electronic parts 6 are fixed on the substrate 5. In the lamp room 13, a UV lamp 10 generates a heat and becomes to high temperature but since cooling gas is circulated in the lamp room 13 by driving a pump P, the temperature in the lamp room 13 is prevented from abnormally rising. Consequently, a reflector 11 is prevented from being stained by smoke emitted from solder flux, etc., the UV light beam projected from the UV lamp 10 transmits a partition 14 and irradiates UV resin and the UV resin is hardened quickly.
