    • Disclosed is a method for insulating external surfaces of a multi-layer ceramic chip varistor device, wherein a high insulating material is coated on external surfaces of the device before the device's external electrodes are plated in an electroplating process. Then after a heat treatment process, the high insulating material reacts with the device's ceramic body surface material to form an insulating layer. A conventional electroplating process for chip devices can be applied to plate the device's external electrodes with a layer of soldering interface so that the external electrodes have a better solderability. The insulating layer protects the device's ceramic body from being plated and the external electrodes are not short-circuited to cause device failure. In addition, if coating the insulating layer is performed before the device's external electrodes are formed, the insulating layer may obstruct a good electric contact to be established between internal electrodes originally exposed out of the ceramic body and the subsequently formed external electrodes. A dip etching method and a heat treatment method are employed to extend the internal electrodes outward so that a good electric contact between the internal and external electrodes is ensured.
    • 公开了一种用于绝缘多层陶瓷片式压敏电阻器件的外表面的方法,其中在电镀工艺中将器件的外部电极镀覆之前,将高绝缘材料涂覆在器件的外表面上。 然后在热处理工艺之后,高绝缘材料与器件的陶瓷体表面材料反应形成绝缘层。 可以应用用于芯片器件的常规电镀工艺以用一层焊接界面对器件的外部电极进行平板化,使得外部电极具有更好的可焊性。 绝缘层保护器件的陶瓷体免受电镀,外部电极不会发生短路,导致器件故障。 此外,如果在器件的外部电极形成之前进行绝缘层的涂覆,则绝缘层可能阻碍在原来露出陶瓷体的内部电极与随后形成的外部电极之间建立良好的电接触。 采用浸渍蚀刻方法和热处理方法将内部电极向外延伸,从而确保内部和外部电极之间良好的电接触。

    • A broad-band microstrip antenna implemented using a dielectric base as its main body is disclosed. The base has two sides where the dual-mode resonator is located on the first side, while the grounded plane is located on the second side of the dielectric base. The dual-mode resonator has a high-frequency resonator and a low-frequency resonator, which are partially positioned in parallel. Due to the electric-magnetic effects, these two resonators are mutually coupled to significantly increase the operating bandwidth. In addition, there is a feed line on the first side of the dielectric base, which connects to the dual-mode resonator to provide signal transmission. In addition, there is a grounded mask in the antenna, which is located on the first side of the dielectric base, to provide sheltering for the feed line, and connect to the grounded plane to form a closed area to provide a more complete radiation field pattern.
    • 公开了使用电介质基底作为其主体实现的宽带微带天线。 基座具有两侧,双模共振器位于第一侧,而接地平面位于电介质基座的第二侧。 双模谐振器具有高频谐振器和低频谐振器,它们被部分地并联放置。 由于电磁效应,这两个谐振器相互耦合以显着增加工作带宽。 此外,在电介质基底的第一侧上有馈电线,该馈电线连接到双模谐振器以提供信号传输。 另外,在天线中有一个接地的掩模,它位于电介质基底的第一面上,为馈电线提供防护,并连接到接地平面,形成一个闭合的区域,以提供更完整的辐射场 模式。
