    • Surface acoustic waves are propagated in a lower-left oblique direction and a lower-right oblique direction from an excitation element located on the upper side of a non-piezoelectric substrate and then received by receiving elements located on the left side and the right side, while surface acoustic waves are propagated in an upper-left oblique direction and an upper-right oblique direction from an excitation element located on the lower side of the non-piezoelectric substrate and then received by the receiving elements located on the left side and the right side. Based on the received results at the two receiving elements, a position of an object in contact with the non-piezoelectric substrate is detected. The sensitivity in a region near the diagonal, which is influenced largely by propagation loss of the surface acoustic waves, is improved by increasing the widths of the electrode fingers of the excitation elements and/or the receiving elements, the number of pairs of the electrode fingers, or the aperture width of comb-like electrodes, according to an increase in the propagation distances of the surface acoustic waves, i.e., toward the region near the diagonal.
    • 表面声波从位于非压电基板的上侧的激励元件沿左下斜方向和右下斜方向传播,然后由位于左侧和右侧的接收元件接收, 同时表面声波从位于非压电基板的下侧的激励元件沿左上方倾斜方向和右上斜方向传播,然后由位于左侧和右侧的接收元件接收 侧。 基于两个接收元件的接收结果,检测与非压电基板接触的物体的位置。 通过增加激发元件和/或接收元件的电极指的宽度,电极对的数量来改善受到表面声波的传播损耗很大影响的对角线附近区域的灵敏度 手指或梳状电极的孔径宽度,根据表面声波的传播距离的增加,即朝向对角线附近的区域的增加。

    • Disclosed is a method to determine a needle mark, which can more accurately determine whether marks formed on electrode pads of devices are probe needle marks, thereby significantly reducing misdetermination of the marks as the probe needle marks. The method includes giving scores, which are used to determine the quality of marks as probe needle marks, to marks formed on a plurality of electrode pads of a plurality of devices, and selecting, based on the scores, an object device including an object electrode pad with an indefinite mark formed thereon, and selecting four comparison devices preceding the object device and nine time-successive comparison devices following the object device at successive times along the test direction, and determining if the indefinite mark of the object device is good or bad as a probe needle mark, by comparing a value of the score given to the indefinite mark of the object device plus scores given to marks formed on the comparison devices' comparison electrode pads corresponding to the object electrode pad, with a reference value.
    • 公开了一种确定针标的方法,其可以更精确地确定形成在装置的电极焊盘上的标记是否是探针针迹,从而显着减少探针针标记时的标记的误定。 该方法包括将用于确定作为探针针迹的标记的质量的分数分配给形成在多个装置的多个电极焊盘上的标记,并且基于分数来选择包括对象电极的对象装置 在其上形成无限度标记,并且在连续的时间沿着测试方向选择在对象设备之前的四个比较设备和跟随对象设备的九个时间连续的比较设备,以及确定对象设备的不定标是否良好 作为探针针标,通过比较给定到对象装置的不定标记的得分的值加上给对应于对象电极垫的比较装置的比较电极垫上形成的标记的评分与参考值进行比较。

    • Each of excitation elements and receiving elements placed in a frame region of a non-piezoelectric substrate is constructed by forming a comb-like electrode on the front face of a piezoelectric body and forming a plate electrode (solid electrode) on the rear face thereof. The comb-like electrode is composed of a bus electrode and a plurality of V-shaped electrode fingers extended from the bus electrode. Drawn-round wires are provided to connect the comb-like electrode (bus electrode) and plate electrode to external circuits. Surface acoustic waves from the excitation elements located on the upper side and the lower side are simultaneously propagated in two directions respectively and the propagated surface acoustic waves are received by receiving elements located on the left side and the right side respectively.
    • 放置在非压电基板的框架区域中的每个激励元件和接收元件通过在压电体的前表面上形成梳状电极并在其后表面上形成平板电极(固体电极)而构成。 梳状电极由总线电极和从总线电极延伸的多个V形电极指构成。 提供拉制圆线以将梳状电极(总线电极)和平板电极连接到外部电路。 来自位于上侧和下侧的激励元件的表面声波分别在两个方向上同时传播,并且传播的声表面波分别由位于左侧和右侧的接收元件接收。
