Patent JP-H02265318-A (JP)
Title: Frequency-voltage conversion circuit
Inventor: FURUYA RYOJI
IPC: H03K9/06
Filed: 1989-04-05
Abstract: PURPOSE:To always obtain a displacement output voltage corresponding only to a 1st frequency signal by separating a 2nd frequency signal in a composite input signal, extracting a correction signal voltage accordingly, and correcting a frequency-voltage conversion output in the composite input signal. CONSTITUTION:The time constant comprising R and C in a composite signal separation retriggerable monostable multivibrator 3 is selected so that a pulse with a width T equal to a minimum frequency change in the 1st frequency signal inputted in a composite signal to a terminal F, that is, a maximum value of a period Hs is outputted at the terminal Q. When only the 1st frequency signal is inputted to the terminal F, the output Q of the vibrator 3 is always positive. Since an inverse amplifier 4 is always set, an output voltage Ec via transistors(TRs) 12 and 12a at an output ec=0 is also 0V. Thus, a frequency- voltage conversion output EF corresponding to the 1st frequency signal is obtained at an output E-Ec of a computing element 13.

IPC: H01L21/66
Filed: 1988-04-06
Abstract: PURPOSE:To improve reliability of soldering, by forming a low melting point metal layer on the pad of a test board to be mounted by soldering a flip chip, and melting the low temperature metal layer at a temperature lower than a temperature to melt a bump of the flip chip. CONSTITUTION:Pads 4 are formed on the surface of a test board 3, so as to correspond with each bump 2 of a flip chip 1, and a low melting point metal layer 5 is formed on the pads 4. The flip chip 1 is so stacked on the board 3 that the spherical bumps 2 formed on the flip chip 1 are suited to the pads 4, and heated at a specified temperature to perform soldering. As a result, the bumps 2 can be soldered to the pads 4 by the low melting point metal layer 5, under the condition where the bumps 2 are not melted. Thereby soldering failure can be prevented, and soldering quality is improved.
