Visual Inspection Visual inspection is the first and most basic aspect of OQC. It involves checking the product for any visible defects or inconsistencies. Some of the things to look for during visual inspection include: Surface Defects Surface defects are any imperfections on the surface of the product, such as Read more…
What is an Aluminum PCB? An Aluminum PCB, also known as a Metal Core PCB (MCPCB), is a type of printed circuit board that uses an aluminum substrate instead of the traditional FR-4 material. The aluminum substrate provides excellent thermal conductivity, allowing for better heat dissipation compared to standard PCBs. Read more…
Introduction to PCB Aluminum Thermal Conductivity Printed Circuit Boards (PCBs) are essential components in modern electronic devices. They provide a platform for mounting and interconnecting electronic components, allowing for the efficient transfer of electrical signals. However, as electronic devices become more compact and powerful, managing heat dissipation becomes a critical Read more…
Introduction to PCB Layers Printed Circuit Boards (PCBs) are the backbone of modern electronics. They are used in almost every electronic device, from smartphones and computers to medical equipment and aerospace systems. PCBs are made up of multiple layers of conductive and insulating materials, each serving a specific purpose. In Read more…
Introduction to Aluminum PCB Boards Aluminum PCB boards, also known as metal core PCBs (MCPCB), are printed circuit boards that use aluminum as the base material instead of the traditional FR-4 substrate. These boards are designed to provide superior thermal management and heat dissipation compared to standard PCBs, making them Read more…
What Is PCB Silkscreen? PCB silkscreen, also known as legend printing or screen printing, is a method of applying text, symbols, and logos onto the surface of a printed circuit board (PCB). The process involves using a fine mesh screen to transfer ink onto the PCB, creating a permanent and Read more…
What is Low Volume PCB Fabrication? Low volume PCB fabrication refers to manufacturing printed circuit boards in small quantities, usually under 100 pieces. This is in contrast to mass production where thousands or tens of thousands of identical PCBs are produced. Low volume production is common for: Prototypes and test Read more…
What is PCB Silkscreen? PCB silkscreen, also known as legend or nomenclature, is the text and symbols printed on the surface of a printed circuit board (PCB) for identification and assembly purposes. The silkscreen layer provides essential information about component placement, orientation, and reference designators, making it easier for manufacturers Read more…
Introduction to PCB Stack-up Printed Circuit Board (PCB) stack-up refers to the arrangement of copper layers and insulating materials that make up a PCB. The stack-up determines the electrical properties, mechanical strength, and manufacturability of the board. A well-designed PCB stack-up is crucial for ensuring signal integrity, power delivery, and Read more…
Introduction to HDI PCB Technology High Density Interconnect (HDI) PCBs have revolutionized the electronics industry by enabling the creation of smaller, lighter, and more powerful devices. HDI PCBs feature finer lines and spaces, smaller vias, and higher connection pad density compared to traditional PCBs. This advanced technology allows for the Read more…
