For those who want to start in a career in smartphone repair, understanding the basics of electronics is essential. This knowledge is essential for diagnosing and troubleshooting equipment efficiently and safely. In this article, we’ll cover the main electronics concepts you need to know to stand out in the smartphone repair market.
Voltage (Voltage)
Voltage, also known as voltage, is the difference in electrical potential between two points in a circuit. It is responsible for propelling the electric current through the components of the circuit. Voltage is measured in volts (V) and is one of the main parameters you need to know when working with electronics applied to smartphone repair.
Electric Current (Amperage)
Electric current, or amperage, is the flow of electrons in an electrical conductor. It is the amount of electrical charge that passes through a point in the circuit in a given time interval. Current is measured in amperes (A) and is another important factor to consider when working with smartphone repair.
Electrical Resistance
Electrical resistance is the ability of a material to hinder the passage of electric current. All materials have a certain strength, which can vary according to their physical and chemical properties. Resistance is measured in ohms (Ω) and is one of the most important concepts in electronics, especially when dealing with components and circuits in smartphones.
Electrical power
Electrical power is the electrical energy converted into work per unit time. It is an indicator of the energy consumption or generation in an electronic device. Power is measured in watts (W) and is an important measurement when dealing with smartphone repair and maintenance, as it indicates how much power a component or circuit is using.
Ohm’s Law
Ohm’s Law is one of the fundamental laws of electronics, establishing the relationship between voltage, current, and resistance in an electrical circuit. According to this law, the voltage applied to a circuit is equal to the product of the electric current and the resistance (V = I × R). Knowing Ohm’s Law is essential for understanding how electronic components work and performing accurate diagnostics on smartphones.
Capacitors & Inductors
Capacitors and inductors are electronic components that store energy and play an important role in smartphone circuitry. Capacitors store energy in the form of an electric field, and inductors store energy in the form of a magnetic field. Knowing how these components work is crucial for identifying and troubleshooting smartphones.
Integrated Circuits (ICs)
Integrated circuits (ICs) are complex electronic components that contain multiple transistors, resistors, condestors, and other elements in a single piece of silicon. ICs are fundamental to the functioning of modern smartphones, and understanding how they work is essential for diagnosing and repairing the problems.
Electrostatic Protection (ESD)
Electrostatic protection (ESD) is an important measure to consider when working with sensitive electronics on smartphones. ESD can damage or destroy components, causing devices to malfunction. Knowing and applying proper ESD protection practices is critical to prevent damage to equipment during the repair process. Learn more about the importance of ESD care in smartphone maintenance here.
Common Mistakes in Smartphone Maintenance
When working with smartphone repair, it’s important to be aware of common mistakes that can occur during the maintenance process. These errors can result in damage to devices or inefficient repairs. Learn about the most common mistakes in smartphone maintenance and how to avoid them here.
Mastering the basics of electronics is crucial for anyone who wants to become a successful professional in the field of repairs. In addition to knowing these fundamentals, it is important to invest in knowledge and constant updating. Good luck!
