Sealing technology plays an important role in protecting electronic devices that require waterproofing from various influences. Sealing refers to the process of enclosing precision components without gaps to prevent exposure to the outside air, as well as the technology involved in this process. Therefore, it serves to protect semiconductors from impact, shield components from external environments such as heat, dust, moisture, and light, and facilitate electrical connections, heat dissipation, and mounting. [Content Overview] ■ Role of Sealing ■ What is the "Hot Melt Molding" that is gaining attention? ■ Applications of Hot Melt Molding *Matsuyama Technical Works specializes in mass production of waterproof components sealed through insert molding.

The optimal shape of an antenna varies depending on the frequency and application. The most efficient antenna is one that is half the length of the wavelength of the frequency being used. High-frequency waves, which are the source of radio waves, have the property of reversing polarity every half wavelength. Therefore, when the length of the antenna conductor exceeds half a wavelength, the transmission and reception of radio waves do not work well. By making the length of the antenna conductor half the wavelength of the frequency, the radio waves resonate with the antenna. By adjusting the length of the antenna according to the wavelength of the frequency, the antenna and the transmitted radio waves enter a resonant state, allowing maximum power to be radiated. Similarly, in a receiver, the received radio waves and the antenna enter a resonant state, enabling the capture of maximum power.
