Introduction to PCB Assembly PCB assembly is the process of attaching electronic components to a printed circuit board (PCB) to create a functional electronic device. It involves soldering components onto the PCB, which is a complex process that requires precision and accuracy. PCB assembly is a crucial step in the […]

History of International Workers’ Day The origins of International Workers’ Day can be traced back to the late 19th century in the United States. During this time, workers were fighting for better working conditions, fair wages, and an eight-hour workday. On May 1, 1886, a general strike was called in […]

What is a Freight Collect Account? A freight collect account, also known as a “bill to” or “third party billing” account, is an arrangement where the shipper’s transportation charges are billed directly to a separate account with the carrier instead of being paid upfront by the shipper. The account holder, […]

In-Circuit Testing (ICT) In-Circuit Testing (ICT) is a powerful testing method used to verify the functionality and connectivity of individual components on a PCBA. ICT is performed using specialized equipment that probes the board’s Boundary Scan Testing Boundary Scan Testing, also known as JTAG (Joint Test Action Group) testing, is […]

What is Fine Pitch PCBA? Fine pitch PCBA refers to the assembly of electronic components on a PCB with a pitch (the distance between the centers of adjacent leads or pads) of less than 0.5mm. This advanced manufacturing technique allows for the placement of components with extremely small lead spacing, […]

Introduction to High-TG PCB High-Tg PCB, or high glass transition temperature printed circuit board, is a type of PCB material that can withstand higher temperatures compared to standard FR-4 PCBs. The glass transition temperature (Tg) refers to the temperature at which the PCB material transitions from a rigid, glassy state […]

What is PCB Assembly Testing? PCB assembly testing, also known as PCBA testing or printed circuit board assembly testing, is the process of validating that a manufactured PCB functions as intended according to its design specifications. The goal is to identify any defects or issues with the assembLED PCB before […]

What are SMD LEDs? SMD LEDs are the most common type of LED used in PCB Assembly. They are small, discrete components that are mounted directly onto the surface of the PCB. SMD LEDs come in various sizes, with the most common being 0402, 0603, 0805, and 1206. The numbers […]

Introduction to E-cigarettes and Recent Studies Electronic cigarettes, also known as e-cigarettes or vapes, have gained significant popularity in recent years as an alternative to traditional tobacco cigarettes. These devices work by heating a liquid solution (e-liquid) that typically contains nicotine, propylene glycol, vegetable glycerin, and flavorings, producing an aerosol […]
