    Abstract: Electric elements such as a resistance chip, a capacitor chip, a semiconductor device package, and a connector are mounted on a printed circuit board by using at least two methods selected from the re-flow method using cream solder, the chip-on board method using bonding wires, the outer lead bonding method, and the thermal pressing method using heat-seal. The printed circuit board is provided with lands having surface layers of a non-electrolysis Ni--Au plate, a soft Au plate and an electrolysis solder plate, each corresponding to a selected mounting method.

    Abstract: The improved liquid-crystal display device has a slit formed in part of the TAB area where the electrodes on the liquid-crystal display panel are connected to the output terminals on the TAB and the liquid-crystal display panel is bonded to the TAB by means of a first anisotropic conductive adhesive having a comparatively weak adhesive force, such as a thermoplastic anisotropic conductive adhesive, whereas a second anisotropic conductive adhesive having a comparatively strong adhesive force, such as a uv curable adhesive, is coated in the slit. This liquid-crystal display device can be produced by a process that proceeds basically as follows: the electrodes on the liquid-crystal display panel are connected to the output terminals on the TAB by means of a thermoplastic adhesive as the first anisotropic conductive adhesive having a comparatively weak adhesive force; then, the assembly is subjected to an operating test; if the TAB is found to be defective in the operating test, it is replaced and, if no defect is found, a uv curable or a thermosetting adhesive as the second anisotropic conductive adhesive having a comparatively strong adhesive force is coated in the slit and then cured as the output terminals are compressed against the electrodes.
