We have talked about the Application of Tantalum Target in Thermal Inkjet Print Head and Copper Plating before, which rises your interest on this element. However, most people think thermal inkjet print and copper plating are far away from their life, thus are difficult to understand. So today, SAM sputter targets will talk about something that EVERYONE is familiar with—your mobile phones.
Tantalum is a very important element in the electronic industry. And it is widely used in all kinds of electronic devices, such as phones and computers. The main use of tantalum materials in electronic products comes in the creation of tantalum capacitor. Tantalum capacitors have their unique advantages over other capacitors. They do not use electrolytes like ordinary electrolytic capacitors, making them ideal for operation at high temperatures. Solid tantalum capacitors have excellent electronic properties, wide operating temperature range, various forms and excellent volumetric efficiency.
Resistive screens and capacitive screens are the two main kinds of mobile screens on the market today. Generally speaking, resistive screen phones can be operated with a finger or a stylus; while capacitive screen phones can only be operated with fingers and cannot be operated with ordinary stylus, but we can use a dedicated capacitive screen stylus to substitute the finger to operate; while the resistive screen phone can be operated with a finger or a stylus. Why do they have such a difference? Is it related to their working principle? Let’s 
First, let’s take a look at the definition of these two words. The vacuum evaporation is carried out by means of resistance heating, electron beam or laser bombardment in an environment with a vacuum of not less than 10-2 Pa, and the
