れていた。Conventionally, in order to make electrical contact with a surface-mounted semiconductor device, this type of printed wiring board has been constructed by positioning the lead portion of the semiconductor device on an electrical contact portion (hereinafter referred to as a pad) on the printed wiring board. The semiconductor device is temporarily fixed with adhesive and then soldered, or the semiconductor device is mounted on a socket soldered onto a printed wiring board.

という欠点を有している。The conventional printed wiring boards mentioned above have the disadvantage that they require accurate positioning and temporary fixing with adhesive when soldering surface-mounted semiconductor devices, and are also prone to poor contact due to positional misalignment. There are drawbacks. Furthermore, when a socket fixed on the substrate is used, there is a drawback that it is difficult to automate the mounting of the surface-mounted semiconductor device.

The purpose of the present invention is to provide a printed wiring board with

めも不要になる。As shown in FIG. 1, a magnetic pad 4 containing magnetic powder 5 is formed on a printed wiring board 1 at its periphery. A surface-mounted semiconductor device 2 is mounted in the center of the substrate 1, but since the leads 3 in this semiconductor device 2 are made of an iron-nickel alloy, strict alignment of the leads 3 is not necessary. Further, accurate alignment is achieved by the magnetic force of the bat 4. Further, temporary fixing with adhesive, which is necessary for soldering the semiconductor device 2 to the substrate 1, is no longer necessary.

This embodiment is an example in which the present invention is applied to electrical measurement of a surface-mounted semiconductor device.

る。As shown in FIG. 2, the bat 4' on the printed wiring board 1 placed on the measuring section 7 of the measuring device 6 is an electromagnet. That is, the pads 3 formed around the semiconductor device 2 are attracted to the pads 4'. First, when the batt 4' is energized at the time when the surface-mounted semiconductor device W2 is supplied from the semiconductor device supply section 8 of the handler 10 to the measurement section 7,
The generated magnetic force causes the surface mount semiconductor device 2 and pad 4' to
Electrical measurements are taken while the two are in electrical contact and held. Next, when the electrical measurement of the semiconductor device 2 is completed, the contact between the surface-mounted semiconductor device 2 and the pad 4' is cut off by stopping the power supply to the bat 4', and the information is sent to the semiconductor device storage section 9 of the handler 10. It is stored using this technology.

効果かある。As explained above, the present invention provides a printed wiring board on which a surface-mounted semiconductor device is mounted, which has a magnetic material in its butt.
Alternatively, by forming the bat to function as an electromagnet when energized, accurate positioning and temporary fixing with adhesive required during the soldering process of the semiconductor device are not required, and contact failure due to positional misalignment is also prevented. There are certain effects. Further, the present invention has the effect that a socket for a measuring device, which is necessary for electrical measurement of a surface-mounted semiconductor device, is not required, and automatic measurement can be carried out extremely easily.
