luxion electrical components: Names for circuit boards include ceramic circuit boards, alumina ceramic circuit boards, aluminum nitride ceramic circuit boards, wiring boards, PCB boards, aluminum substrate boards, high-frequency boards, thick copper boards, impedance boards, PCB, ultra-thin wiring boards, ultra-thin circuit boards, and printed (copper etching technology) circuit boards. Circuit boards miniaturize and visualize circuits, playing an important role in the mass production of fixed circuits and optimizing appliance layouts. Circuit boards may be referred to as printed wiring boards or printed circuit boards. Flexible wiring boards and flexible circuit boards are a type of highly reliable, highly flexible printed circuit board made using polyimide or polyester film as the base material. They feature high wiring density, light weight, thin profile, and good bendability.) and rigid-flex boards—the emergence and development of FPC and PCB gave rise to the new product category of rigid-flex boards. Therefore, rigid-flex boards are circuit boards formed by combining flexible wiring boards and rigid wiring boards through lamination and other processes according to relevant process requirements, resulting in a board with both FPC characteristics and PCB characteristics.

luxion electrical component principles

LCD is a display that uses liquid crystal as the material. Liquid crystals are a class of organic compounds intermediate between solid and liquid states. At room temperature, they exhibit both the fluidity of liquids and the optical anisotropy of crystals. Heating turns them into a transparent liquid state, while cooling turns them into a crystalline, opaque solid state. Under the influence of an electric field, the arrangement of liquid crystal molecules changes, thereby affecting the intensity of incident light passing through the liquid crystal. This change in light intensity is further manifested as a change in brightness through the action of polarizers. Accordingly, controlling the electric field of the liquid crystal allows for changes in light brightness, achieving the purpose of information display. Thus, the function of liquid crystal material is similar to that of small "light valves." Since control circuits and drive circuits exist around the liquid crystal material, when electrodes in the LCD generate an electric field, the liquid crystal molecules twist, causing regular refraction of the light passing through them (the optical rotation of the liquid crystal material), which is then filtered by a second polarizer and displayed on the screen. It is worth noting that because liquid crystal material does not emit light itself, LCD displays typically require an additional light source configured for the display panel. The main light source system is called the "backlight module," in which the backlight plate is composed of fluorescent materials that emit light, primarily providing a uniform backlight source.

luxion electrical component applications

Specialized solid-state relays can feature short-circuit protection, overload protection, and overheat protection functions. When encapsulated with combined logic solidification, they can realize intelligent modules required by users, directly applicable in control systems. Solid-state relays are widely used in computer peripheral interface equipment, constant temperature systems, temperature regulation, electric furnace heating control, motor control, CNC machinery, remote control systems, and industrial automation devices; signal lights, dimming, flashers, stage lighting control systems; instruments and meters, medical devices, copiers, automatic washing machines; automatic fire protection, security systems, and as switching switches for power capacitors for grid power factor compensation. Additionally, they are extensively used in chemical, coal mining, and other environments requiring explosion-proof, moisture-proof, and corrosion-resistant properties.

luxion electrical component performance

(1) Electromotive force: Electromotive force is the difference between the equilibrium electrode potentials of two electrodes. (2) Rated capacity: The theoretical capacity of a battery can be precisely calculated based on the amount of active electrode material in the battery reaction equation and the electrochemical equivalent of the active material calculated according to Faraday's law. Due to possible side reactions in the battery and special design needs, the actual capacity of the battery is often lower than the theoretical capacity. (3) Rated voltage: The typical operating voltage of a battery at room temperature, also known as nominal voltage. It serves as a reference when selecting different types of batteries. The actual operating voltage of a battery equals the difference between the equilibrium electrode potentials of the positive and negative electrodes under different usage conditions. It is related only to the type of electrode active material, not to the quantity of active material. Battery voltage is essentially DC voltage, but under certain special conditions, phase changes in metal crystals or certain formation films caused by electrode reactions can cause minor voltage fluctuations, a phenomenon known as noise. The amplitude of fluctuation is small, but the frequency range is wide, distinguishing it from self-excited noise in circuits. (4) Open-circuit voltage: The terminal voltage of a battery in an open-circuit state is called the open-circuit voltage. The open-circuit voltage of a battery equals the difference between the positive electrode potential and the negative electrode potential when the battery is in an open circuit (i.e., no current flows through the two poles). The open-circuit voltage of a battery is denoted by V open. The open-circuit voltage of a battery is generally less than its electromotive force. This is because the electrode potentials established by the two poles in the electrolyte solution are usually not equilibrium electrode potentials, but stable electrode potentials. It can generally be approximated that the open-circuit voltage of a battery is its electromotive force. (5) Internal resistance: Battery internal resistance refers to the resistance encountered when current passes through the interior of the battery. It includes ohmic internal resistance and polarization internal resistance; polarization internal resistance further includes electrochemical polarization internal resistance and concentration polarization internal resistance. Due to the existence of internal resistance, the working voltage of a battery is always less than the electromotive force or open-circuit voltage of the battery. Battery internal resistance is not constant; it changes continuously over time (gradually increasing) during charging and discharging because the composition of active materials, electrolyte concentration, and temperature are constantly changing. Ohmic internal resistance obeys Ohm's law. Polarization internal resistance increases with increasing current density, but not linearly; it commonly increases as current density increases. Internal resistance is an important indicator determining battery performance, directly affecting the battery's working voltage, working current, output energy, and power. For batteries, the smaller the internal resistance, the better. (6) Impedance: Batteries have a large electrode-electrolyte interface area, so a battery can be equivalent to a series circuit of a large capacitor with small resistance and inductance. However, the actual situation is much more complex, especially since battery impedance changes with time and DC level. The measured impedance is only valid for the specific measurement state. (7) Charge/discharge rate: There are two representation methods: hour rate and C-rate. The hour rate expresses the charge/discharge rate in terms of charge/discharge time, numerically equal to the number of hours obtained by dividing the battery's rated capacity (ampere-hours) by the specified charge/discharge current (amperes). C-rate is another representation of charge/discharge rate, numerically the reciprocal of the hour rate. The discharge rate of primary batteries is expressed by the time taken to discharge through a fixed resistor to the termination voltage. Discharge rate has a significant impact on battery performance. (8) Service life: Storage life refers to the maximum allowable storage time from battery manufacture to the start of use, measured in years. The total period including the storage period and usage period is called the battery's validity period. The storage life of batteries is divided into dry storage life and wet storage life. Cycle life is the maximum number of charge/discharge cycles a rechargeable battery can achieve under specified conditions. When specifying cycle life, the charge/discharge cycle test regime must also be specified, including charge/discharge rate, depth of discharge, and ambient temperature range. (9) Self-discharge rate: The rate at which a battery loses capacity on its own during storage. It is expressed as the percentage of capacity lost due to self-discharge per unit of storage time relative to the capacity before storage.
