Integrated Circuits

Integrated Circuits (also chips or microchips) are usually a group of electronic circuits on a small plate of silicon semiconductor materials. Integrating large miniature MOS transistors into a small chip, the resulting circuit is smaller, faster, and cheaper than that of the discrete electronic.

Power Supply

A power supply is a device that takes an incoming electrical current and amplifies it to levels required by various devices. In many instances, this type of device is also implemented to take the incoming electricity and deliver it across many other electronic devices, often at different preset levels. Power supply is used to transform various types of power into a compatible format to be stored, like solar energy to electrical energy.

Relay 9.9

Relay

A relay is composed of an electromagnet and a contact mechanism. It is defined as “a device that actuates a contact mechanism, using an electromagnetic attractive force that is generated when a current of a certain value or more flows through an electromagnet. It opens and closes a contact through voltage and current (input signal) applied to a coil.”
Simply speaking, a relay receives an electric signal from a switch, etc., and transmits the signal to an output unit, such as a motor.

Battery

A battery is a device with a collection of one or more cells that forces flow of electrons in a circuit through electrochemical reaction. It actually transforms stored chemical energy directly into electrical energy. All types of batteries have: an anode (Negative Terminal), a cathode (Positive Terminal), and some chemical called electrolyte for chemical reaction. Most batteries consist of 3 components: Electrodes, Electrolyte and Separator.

LCDs

LCD (Liquid Crystal Display). It uses liquid crystal as an optical material to make a display. LCD is the main component of digital display, can display text, pictures and video. It is not only widely used in electronic products such as computers, televisions and mobile phones, but also occupies an important position in display equipment in industrial, medical and other fields.

PCBA

PCBA is the abbreviation of Printed Circuit Board +Assembly, that is to say, the PCB empty board through the SMT on the piece, or through the DIP plug-in the entire process, referred to as PCBA. It is widely used in control circuit, signal processing, instrument measurement and other fields. Due to its high stability and reliability, PCBA is often used as a component of high-quality electronic devices. PCBA is also widely used in automotive, aircraft, communications and home appliances.
