Introduction to Solder Paste Volume for QFP Packages Solder paste volume is a critical factor in the successful assembly of Quad Flat Package (QFP) components onto printed circuit boards (PCBs). Applying the correct amount of solder paste is essential for achieving reliable solder joints and ensuring the overall quality of […]

What is Solder? Solder is a fusible metal alloy used to create a permanent bond between metal surfaces. It typically has a lower melting point than the metals being joined, allowing it to be melted and flowed into the joint without damaging the components. The most common types of solder […]

Introduction to SMT Soldering Surface mount technology (SMT) has revolutionized the electronics manufacturing industry since its introduction in the 1960s. SMT soldering involves attaching surface-mount components directly onto the surface of a printed circuit board (PCB), as opposed to through-hole soldering where component leads are inserted into holes drilled in […]

What is Automated Optical Inspection? Automated Optical Inspection is a computerized visual inspection system that uses cameras, lighting, and image processing software to automatically detect and identify defects in manufactured products. AOI systems capture high-resolution images of the inspected object and compare them against a predefined set of criteria or […]

What is SMT PCB Assembly? SMT (Surface Mount Technology) PCB (Printed Circuit Board) assembly is the process of attaching electronic components directly onto the surface of a printed circuit board. This is in contrast to through-hole technology, where component leads are inserted into holes drilled in the PCB and soldered […]

Introduction to the PiGRRL Pack The PiGRRL Pack is an all-in-one kit that allows you to build your own portable gaming console powered by a Raspberry Pi single-board computer. Version 2.0 of the PiGRRL Pack features compatibility with the more powerful Raspberry Pi 2 Model B along with a newly […]

Introduction to Raspberry Pi and Arduino in Industrial Settings The Raspberry Pi and Arduino are two popular single-board computers that have revolutionized the world of electronics and computing. While they were initially designed for educational and hobbyist purposes, their versatility, low cost, and ease of use have made them increasingly […]

Introduction to PCB Recreation Printed Circuit Boards (PCBs) are the backbone of modern electronics. They provide a compact and efficient way to connect electronic components together into a functional circuit. However, sometimes you may need to recreate an existing PCB, either because the original design files are lost, or you […]

What are Castellated Solder Pads? Castellated solder pads, also known as castellated holes or castellations, are a type of surface mount technology (SMT) used in printed circuit board (PCB) design. These pads are essentially a series of half-holes or semi-circular cutouts along the edge of a PCB, resembling the battlements […]

Understanding PCB Pads Definition and Purpose PCB pads are the conductive surfaces on a printed circuit board where electronic components are attached. They serve as the connection points between the components and the copper traces that form the electrical pathways on the PCB. Pads are typically made of copper and […]
