Abstract: PURPOSE:To increase the quality in soldering by forming the groove having the same pitch as that of the pattern of a printed circuit board on the opposite face to the printed circuit board of a heating tip. CONSTITUTION:A printed circuit board 2 positioned by a positioning mechanism 6 and a flat package IC7 is fitted on the pattern of the printed circuit board 2 by a double faced tape, etc. The printed circuit board 2 is removed by ascending the heating tip 1 after completion of soldering by heating the heating tip 1 by pushing it to the reed terminal 5 of the package IC7 by a heating tip vertical feed mechanism 8. In this case, the groove having the same pitch as the printed circuit board pattern pitch is formed on the opposite face to the printed circuit board 2 of the heating tip 1. Accordingly, even in case of the positional relation of the reed terminal 5 to be soldered and the pattern 3 of the printed circuit board 2 being discordant, the discordance thereof is corrected on the way of the descent of the heating tip 1 and the reed terminal 5 is accurately soldered on the pattern 3.

Abstract: PURPOSE:To eliminate need of formation of an electrode and application of bias voltage to a specimen and allow evaluation of a thin nitride film thinner than a specific thickness by obtaining film potential of the nitride film formed on a surface of a semiconductor from a size of ac photo voltage. CONSTITUTION:A continual light beam is applied to a desired position of a semiconductor wafer 1 after transmitting via a light beam scanning optical system 9 comprising a galvano mirror and a lens through a transparent electrode 3 and glass 4. Ac photo voltage is generated on the wafer 1 by the application of the continual light 5.

The sensed ac photo voltage signal is amplified by a preamplifier 11 which can convert from high input impedance to low impedance, and then detected synchronously with an electrical output signal of an oscillator 8 by a synchronous wave detector 12. The output signal of the synchronous wave detector 12 is made into a digital signal in an A/D- converter 13 and processed in an MPU 15 via an interface 14. Thus evaluation of a thin nitride film 10 mm or thinner is possible.
