Introduction to PCB Quality and Failure Analysis Printed Circuit Boards (PCBs) are essential components in almost all modern electronic devices. The quality of PCBs directly impacts the performance, reliability, and longevity of these devices. Poor quality PCBs can lead to device malfunctions, short circuits, and even complete failures. Therefore, ensuring […]

Introduction to PCB Lay-up PCB (Printed Circuit Board) lay-up is a crucial step in the multi-layer PCB fabrication process. It involves stacking and aligning multiple layers of the PCB, including the core, prepreg, and copper foil, to create a compact and functional circuit board. The lay-up process ensures that the […]

What is ENEPIG? ENEPIG, short for Electroless Nickel Electroless Palladium Immersion Gold, is a multi-layer surface finish that consists of three distinct layers: Electroless Nickel (Ni): This layer acts as a barrier between the copper substrate and the subsequent layers, providing excellent corrosion resistance and a uniform surface for the […]

What is Solderability Testing? Solderability testing is a process used to evaluate the ability of electronic components and printed circuit boards (PCBs) to be soldered effectively. It assesses the wettability and adhesion properties of the surfaces to be soldered, ensuring reliable electrical connections and mechanical strength. Solderability testing is crucial […]

Introduction to High-Tg PCBs High-Tg PCBs, also known as high glass transition temperature printed Circuit Boards, are a type of PCB that can withstand higher temperatures compared to standard PCBs. The glass transition temperature (Tg) refers to the temperature at which the material transitions from a rigid, glassy state to […]

What is a Printed Circuit Board (PCB)? A printed circuit board, or PCB, is a fundamental component in modern electronic devices. It is a flat board made of insulating materials, such as fiberglass or composite epoxy, with conductive pathways etched or printed onto its surface. These pathways, known as traces, […]

What Is PCB Potting? PCB potting is a process that involves encapsulating the entire PCB and its components in a solid, protective compound. The potting material, typically a two-part epoxy or polyurethane resin, is poured over the PCB and allowed to cure, forming a solid, impenetrable barrier around the board. […]

What is AOI Inspection? AOI (Automated Optical Inspection) is a critical process in the manufacturing of printed circuit boards (PCBs) and other electronic components. It involves using specialized cameras and image processing software to automatically inspect the quality of manufactured products for defects, such as missing components, incorrect component placement, […]

Understanding PCB Layers Before diving into the comparison between 2 layer and 4 layer PCBs, let’s first understand what PCB layers are and their significance. What are PCB Layers? PCB layers refer to the number of conductive copper layers within a PCB. These layers are used to route electrical signals […]
