Introduction to Surface Mount Technology Surface Mount Technology (SMT) has revolutionized the electronics manufacturing industry since its introduction in the 1980s. SMT involves mounting electronic components directly onto the surface of a Printed Circuit Board (PCB), as opposed to the traditional through-hole method where component leads are inserted into holes […]

What is soldering? Soldering is a process of joining two or more metal parts together by melting and applying a filler metal (solder) into the joint. The solder has a lower melting point than the adjoining metal, allowing it to flow into the joint and create a strong bond when […]

Key features found on the PCB Bottom Solderpads Solderpads, also known as footprints or land patterns, are exposed metal areas on the bottom of the PCB where components leads are soldered. The size, shape and spacing of the pads match the component package so it can be properly soldered in […]

What is PCB Assembly? PCB assembly, also known as printed circuit board assembly or PCBA, is the process of soldering or assembly of electronic components onto a printed circuit board (PCB). It is a crucial step in the manufacturing process of electronic devices, as it involves the placement and connection […]

Importance of Solder paste testing Solder paste is a mixture of tiny solder particles suspended in a flux medium. It is applied to the PCB pads using a stencil printing process before placing the surface mount components. The quality of the solder paste printing directly affects the following: Component placement […]

Introduction to PCB sensor placement Printed Circuit Boards (PCBs) are essential components in modern electronic devices. They provide a platform for mounting and interconnecting various electronic components, including sensors. Proper placement of sensors on a PCB is crucial for ensuring optimal performance, reliability, and functionality of the device. In this […]

What are PCB Fiducials? PCB fiducials, also known as fiducial markers or alignment marks, are small copper circles or other shapes etched onto printed circuit boards (PCBs) that serve as reference points for assembling, inspecting, and testing the boards. Fiducials help machines precisely locate and orient the PCB during automated […]

What are PCB Castellations? PCB castellations are a type of edge connector feature found on printed circuit boards (PCBs). They are small, semi-circular cuts or plated half-holes arranged along the edge of a PCB, resembling the battlements of a castle wall, hence the name “castellations.” These castellations serve as connection […]

What are PCB Outlines? PCB outlines, also known as PCB board outlines or PCB contours, refer to the physical shape and dimensions of a printed circuit board (PCB). The outline defines the external boundaries of the PCB and includes any cutouts, notches, or special features required for the board’s intended […]

Introduction to PCB Manufacturing Printed Circuit Boards (PCBs) are the backbone of modern electronics. They provide a platform for electrical components to be mounted and connected, enabling the creation of complex circuits in a compact and organized manner. PCB manufacturing is a multi-step process that involves various techniques and technologies […]
