Patent JP-H11145604-A (JP)
Title: Soldering of component and manufacture of circuit board
Inventor: IWATA YASUHIRO
IPC: H05K3/34
Filed: 1998-08-20
Abstract: PROBLEM TO BE SOLVED: To make it possible to obtain a full component fixing in soldering an electronic component without using a flux, by a method wherein the electronic component is adhered to a board with a material having a boiling point lower than the melting point of solder via the solder and the board and the electronic component are heated at a melting point higher than that of the solder to solder the component to the board. SOLUTION: A ceramic board 1 mounted with an electronic component 5 is preheated at 120 deg.C or thereabouts in a reflow furnace and is carried, but during this time when the board 1 is preheated and is carried, solder materials 3 are covered with a liquid 4 and are prevented from being subjected to oxidation or the like. The liquid 4 starts evaporation immediately before the solder 3 melts and the materials 3 and connection patterns 2 start bonding. At this time, even if the materials 3 are somewhat deviated from the patterns 2 when the materials 3 are aligned with the patterns 2, the liquid 4 gives buoyancy to the component 5 in a form of accelerating a self-alignment effect. After the reflow of the materials 3, there is no residues of the liquid 4 and a cleaning process for removing these residues is not needed.  As a result, the component 5 and the like can be reliably secured and fixed on the patterns 2.

Title: Generating circuit of dc reference voltage
Inventor: SATOU MITSURU
IPC: H03K3/02
Filed: 1982-12-29
Abstract: PURPOSE:To obtain the reference voltage of a low level by separating the 1st transistor TR which actuates a constant current soruce to which the power is supplied and another TR which inactivates the 1st TR from an impedance element and a control circuit respectively. CONSTITUTION:When the power is supplied to a terminal 12, TR3', 4 and 16 conduct. Thus the current flows to impedance elements 7, 8 and 9 which are connected to the collector of the TR3', and the voltage is generated at an output terminal 13. At the same time, a TR2 conducts to connect the conduction between the TR3' and 4. Thus the output is stabilized by the TR2 and a resistance 11. Furthermore a TR15 conducts with the conduction of the TR3'. Then a TR16 is cut off, and the operation of a starting circuit 20 is stopped. Here the resistance 11 receives no limitation since it is not used for discontinuation of the operation of the circuit 20. Thus the output can be reduced down to the base- emitter voltage of the TR2 by selecting the elements 7, 8 and 9 and the resistance 11 respectively.
