Title: Soldering device
Inventor: MORI TAKESHI
IPC: H05K3/34
Filed: 1980-05-19
Abstract: PURPOSE:To perform good soldering free from any miss by juxtaposing the 1st soldering tank which produces solder flow in the conveying direction of printed substrates and has means of accelerating this, and the 2nd soldering tank which produces solder flow in the direction opposite from the conveying direction of the substrates, and performing continuous soldering in both soldering tanks. CONSTITUTION:This is a device for soldering between prescribed conductor parts on a printed substrate 12 packaged with electric parts. This device is juxtaposed with the 1st soldering tank 105 and the 2nd soldering tank 102. When the fan 104a of a soler flow generator 104 is rotated, solder flow in the direction spposite from the conveying direction of the substrate 12 is produced in the tank 102 and the solder flow in the same direction as the conveying direction of the substrate 12 is produced in the tank 105 by way of a communicating part 103. There is a solder flow accelerator 110 in the tank 105, and the solder flow is further accelerated by the revolution of a grooved revolving shaft 110a. The printed substrate 12 is soldered continuously by these two soldering tanks.

Filed: 1986-03-24
Abstract: PURPOSE:To obtain a power semiconductor element having high reliability by preventing a heat-transmission over various electrical component parts on a control circuit substrate of heat generated by a semiconductor element for power on a power circuit substrate. CONSTITUTION:A space section 22 in which an air layer is shaped is formed between a power circuit substrate 1 and a laminated circuit substrate 2 while a communicating hole 24 through which the air layer is communicated with the outside is shaped to the peripheral wall section of a resin outer frame 4 for molding. Consequently, heat generated by a semiconductor element 10 for power arranged onto the power circuit substrate 1 is heat-insulated by the air layer generating the convection of the space section 22 in the power semiconductor device. Accordingly, the conduction of heat to the control circuit substrate 2 is prevented, thus obviating the thermal deterioration of various electrical component parts 12 on the control circuit substrate 2.
