Introduction to Rigid PCBs and Flex PCBs Printed Circuit Boards (PCBs) are essential components in modern electronics, providing a platform for mounting and interconnecting electronic components. PCBs come in various types, each designed to cater to specific requirements and applications. Two common types of PCBs are Rigid PCBs and Flex […]

What is OSP PCB Finish and Why is it Used? Organic Solderability Preservative (OSP) is a widely used surface finish for Printed Circuit Boards (PCBs). OSP is applied to the copper pads and traces on a PCB to prevent oxidation and maintain solderability during storage and assembly. Compared to other […]

Introduction to Flip Chip Resistors Flip chip resistors are a type of surface mount resistor that offer superior performance compared to traditional resistor packages. They are designed with the resistive element facing down, which allows for better thermal dissipation and improved electrical characteristics. This unique construction makes flip chip resistors […]

Introduction to PCBs and 3D Printer Printing Heads A printed circuit board, or PCB, is used to mechanically support and electrically connect electronic components using conductive pathways, tracks or signal traces etched from copper sheets laminated onto a non-conductive substrate. PCBs are widely used in electronics to hold chips and […]

PCB CAD Software Giant Shifts Focus to American Market In a significant move that is set to reshape the landscape of the electronic design automation (EDA) industry, Altium, a leading provider of PCB CAD software, has announced the relocation of its core research and development (R&D) and PCB CAD division […]

Introduction to Axial Flux BLDC Motors Axial flux permanent magnet brushless DC (BLDC) motors have gained significant attention in recent years due to their high power density, compact design, and excellent efficiency. Unlike traditional radial flux motors, axial flux motors have their magnetic flux flowing parallel to the motor’s rotational […]

What is Soldermask CTI? Soldermask CTI (Comparative Tracking Index) is a measure of a printed circuit board’s (PCB) ability to resist electrical tracking across its surface under high voltage and humid conditions. CTI ratings range from 0 to 600 volts, with higher numbers indicating better insulation performance and resistance to […]

Introduction to Double-Sided SMT Assembly Double-sided Surface Mount Technology (SMT) assembly is a process used in the manufacturing of printed circuit boards (PCBs) where electronic components are mounted on both sides of the board. This technique allows for higher component density, improved performance, and reduced board size compared to single-sided […]

What is Impedance Matching in PCB Design? Impedance matching is a critical aspect of PCB design that ensures optimal signal integrity and power transfer between a source and load. In PCB design, impedance matching refers to the process of matching the characteristic impedance of a transmission line (such as a […]

Introduction to PCB Stackup Printed Circuit Board (PCB) stackup refers to the arrangement of copper and insulating layers that make up a PCB. It is a crucial aspect of PCB design, as it determines the board’s electrical properties, mechanical strength, and manufacturability. Proper PCB stackup planning is essential to ensure […]
