What is Back Drilling in PCB Manufacturing? Back drilling, also known as controlled depth drilling or back-side drilling, is a PCB manufacturing process used to remove unused portions of through-hole vias in high-speed printed circuit board designs. In a standard PCB design, a through-hole via extends through the entire thickness […]

Introduction to Biasing Resistors In digital electronics, biasing resistors are essential components used to ensure that digital inputs are correctly biased to a known logic level, either high (logical 1) or low (logical 0). Two common types of biasing resistors are pull up resistors and pull down resistors. These resistors […]

Introduction to RS485 Serial Interface RS485, also known as TIA-485-A, EIA-485 or RS-485, is a standard defining the electrical characteristics of drivers and receivers for use in serial communications systems. It is widely used for industrial automation, building automation, and other applications requiring robust, long-distance serial data transmission. RS485 enables […]

Introduction to Bluetooth Positioning Bluetooth is a wireless technology standard for exchanging data over short distances from fixed and mobile devices, and building personal area networks (PANs). It uses short-wavelength UHF radio waves in the ISM band from 2.4 to 2.485 GHz, and was invented by telecom vendor Ericsson in […]

ATM Anatomy The anatomy of an ATM can be broken down into several key components: Display Screen The display screen is the primary interface for the user to interact with the ATM. It displays instructions, prompts, and information to guide the user through their transaction. Modern ATMs often use touch […]

What is an OLED Display? Before diving into the specifics of the SSD1306, let’s briefly discuss OLED displays. OLED displays are a type of flat panel display technology that uses organic compounds to emit light when an electric current is applied. Compared to traditional LCD (Liquid Crystal Display) technology, OLED […]

What is PCB Soldering? PCB soldering is the process of joining electronic components to a printed circuit board (PCB) using a molten metal alloy called solder. The solder creates a strong electrical and mechanical bond between the component leads and the PCB’s copper pads, ensuring a reliable connection. Types of […]

What is PCB Soldering? PCB soldering is the process of joining electronic components to a printed circuit board using a low-temperature molten metal alloy called solder. The solder forms a strong electrical and mechanical bond between the component leads and the copper pads on the PCB. Soldering allows for the […]

Introduction to PCB materials When it comes to designing and manufacturing electronic devices, one of the most critical components is the Printed Circuit Board (PCB). PCBs serve as the backbone of electronic devices, providing a platform for interconnecting electronic components and ensuring reliable performance. Choosing the right PCB material is […]
