Understanding SMD Components Surface Mount Devices, as the name suggests, are electronic components that are designed to be mounted directly onto the surface of a Printed Circuit Board (PCB). Unlike through-hole components, which require drilled holes for their leads to pass through the board, SMDs have small metal pads or […]

What is an AOI Test? An Automated Optical Inspection (AOI) test is a automated visual inspection process used to detect defects or anomalies in printed circuit board (PCB) assemblies. AOI tests use high-resolution cameras and image processing software to quickly scan and analyze PCBs for missing components, incorrect component placement, […]

Introduction to PCBA Drawing Requirements Printed Circuit Board Assembly (PCBA) is a crucial process in the manufacturing of electronic devices. It involves assembling various components onto a printed circuit board (PCB) to create a functional electronic system. To ensure the success of the PCBA process, it is essential to have […]

Introduction to Raspberry Pi Camera The Raspberry Pi is a popular single-board computer that has revolutionized the world of DIY electronics and computing. One of the most exciting features of the Raspberry Pi is its ability to connect to a camera module, allowing users to capture images and record videos. […]

Introduction to PCBs and Why Custom PCBs Matter Printed Circuit Boards (PCBs) are the foundation of nearly all modern electronic devices. These flat boards, made from insulating materials like fiberglass, have conductive pathways etched or printed on them to create electrical connections between components. PCBs allow for the miniaturization and […]

What is Stray Capacitance? Stray capacitance, also known as parasitic capacitance, refers to the unintentional and unwanted capacitance that exists between conductors in an electronic circuit. This capacitance arises due to the proximity of conductors, the presence of dielectric materials, and the geometry of the circuit layout. In an ideal […]

What are Proximity Switches? Proximity switches, also known as proximity sensors, are devices that detect the presence or absence of an object without physical contact. They operate by emitting an electromagnetic field or beam of electromagnetic radiation and detecting changes in the field or return signal caused by the presence […]

Introduction to Crystal Oscillators A crystal oscillator is an electronic circuit that uses the mechanical resonance of a vibrating crystal of piezoelectric material to create an electrical signal with a precise frequency. This frequency is often used to keep track of time, provide a stable clock signal for Digital Integrated […]

What is a pH Sensor? A pH sensor is a device that measures the hydrogen ion activity in a solution, indicating its acidity or alkalinity. The pH scale ranges from 0 to 14, with 7 being neutral, values below 7 being acidic, and values above 7 being alkaline or basic. […]

Understanding High-tech PCBs High-tech PCBs are designed to meet the stringent requirements of modern electronic devices, which often involve complex circuitry, high-speed data transmission, and demanding operating conditions. These PCBs are characterized by their advanced features, such as: High layer count High frequency operation High-speed signal integrity Compact form factors […]
