What is PCB and how does it work?

 A Printed Circuit Board (PCB) is a fundamental component in electronic devices, providing the physical structure to mount and connect electronic components. The process of working with a PCB involves designing, fabricating, assembling, and testing. Below is a simplified guide on how to work with a PCB: 1. Designing a PCB PCB design is the first and crucial step. It involves creating a blueprint of the electrical circuit that will be etched onto the board. Choose PCB Design Software : Common tools include KiCad , Eagle , Altium Designer , or EasyEDA . Schematic Diagram : Create a schematic that shows how components are connected (e.g., resistors, capacitors, ICs). Component Placement : In the PCB design software, place components on the board. The design should consider the physical size and pin connections of the components. Routing : This is the process of connecting the components via traces (the electrical pathways). Ensure proper routing to minimize interference and avoid s...

Classification of pumps and their working principles | TECHNOLOGY FACTS

positive displacement pumps Positive displacement pumps are a type of pump that operates by using mechanical action to displace fluid from an inlet to an outlet. These pumps are designed to move a fixed amount of fluid per cycle or revolution and are known for their ability to generate high pressures, handle viscous liquids, and maintain a consistent flow rate. They are widely used in various industries, including oil and gas, chemical processing, food and beverage, pharmaceuticals, and water treatment. Here are some key characteristics and types of positive displacement pumps: Principle of Operation: Positive displacement pumps work by trapping fluid in a cavity and then forcing it out to create flow. The cavity expands and contracts as the pump's mechanism moves, thereby generating the desired fluid displacement. Fixed Displacement: These pumps move a fixed volume of fluid per cycle, regardless of the system pressure. This characteristic makes them suitable for applications requi...

The fundamentals of satellite | How satellite works | TECHNOLOGY FACTS

How does a satellite work step by step? Satellites are man-made objects that are launched into space and orbit around the Earth or other celestial bodies. They are used for various purposes, including communication, weather monitoring, navigation, scientific research, and military applications. Here's a simplified explanation of how satellites work: Launch: Satellites are launched into space using powerful rockets. Once the rocket reaches a specific altitude and speed, it releases the satellite into its designated orbit. Orbit: Satellites travel in a specific orbit around the Earth, following a path determined by their mission requirements. There are several types of orbits, including geostationary orbit (GEO), low Earth orbit (LEO), medium Earth orbit (MEO), and polar orbit. Communication: Communication satellites are equipped with transponders, which receive signals from ground-based sources and retransmit them back to Earth. These satellites act as "relays" in space, e...

Parts of internal combustion engines (Petrol, Diesel, Gasoline, Electric) | TECHNOLOGY FACTS

What are the components of a petrol vehicle. Engine: The engine is where fuel combustion takes place. In a petrol vehicle, it's typically a four-stroke internal combustion engine. It has cylinders where pistons move up and down. The intake stroke draws in a mixture of air and petrol, the compression stroke compresses this mixture, the power stroke ignites it with a spark from the spark plugs, and the exhaust stroke expels the resulting exhaust gases. Fuel System: The fuel system starts with the fuel tank where petrol is stored. The fuel pump draws petrol from the tank and sends it to the engine through fuel lines. In modern vehicles, fuel injectors spray the petrol directly into the engine's cylinders. In older vehicles, a carburetor mixes air and fuel before sending it to the engine. Exhaust System: After the fuel is burnt in the engine, the exhaust system manages the resulting gases. The exhaust manifold collects these gases from the cylinders. The gases then pass through the...

How does a fan work step by step?| What is the operating principle of a celling fan? | TECHNOLOGY FACTS

How does a fan work mechanically.  How celling fan work Ceiling fans work by utilizing the principles of aerodynamics and mechanical engineering to circulate air in a room, creating a cooling effect through increased air movement. Here's how a typical ceiling fan operates: Motor: The fan's motor is housed within the fan's motor housing, usually mounted to the ceiling. This motor is responsible for turning the blades. Blades: Ceiling fans typically have 3 to 5 blades attached to a central hub. These blades are angled to efficiently move air. The angle of the blades is designed to push air downwards when rotating in a counterclockwise direction (as viewed from below), creating a cooling breeze in the room. In some cases, ceiling fans have reversible motors, allowing the blades to rotate in a clockwise direction to pull air upwards, which can be beneficial in cooler months to help distribute warm air trapped near the ceiling. Rotation: The motor rotates the blades when electri...

SSD vs HDD Advantages and Disadvantages | SRAM and DRAM | computer components | Technological Innovations

  SSD (Solid State Drive): Advantages: Faster Speed: SSDs offer significantly faster data access and transfer speeds compared to HDDs. Durability: SSDs have no moving parts, making them more durable and less prone to mechanical failure. Energy Efficiency: SSDs consume less power, leading to improved battery life in laptops. Compact Size: SSDs are smaller and lighter than HDDs, making them ideal for slim devices. Disadvantages: Cost: SSDs are generally more expensive per gigabyte compared to HDDs. Limited Write Cycles: SSDs have a limited number of write cycles per cell, though modern SSDs are designed to handle this well. Capacity: High-capacity SSDs can be expensive, limiting cost-effective storage for large amounts of data. HDD (Hard Disk Drive): Advantages: Cost: HDDs are more cost-effective in terms of storage capacity. Storage Capacity: HDDs are available in larger capacities, making them suitable for storing large amounts of data at a lower cost. Established Technology: HDDs ...
