Introduction to 2-Layer PCBs A 2-layer PCB, also known as a double-sided PCB, is a printed circuit board that consists of two conductive copper layers separated by an insulating substrate material. These layers are referred to as the top layer and the bottom layer. 2-layer PCBs are widely used in […]

Introduction to USB routing USB (Universal Serial Bus) is a widely used standard for connecting devices to computers or other electronic systems. Proper USB routing is crucial for ensuring reliable data transmission and maintaining signal integrity. When designing a PCB (Printed Circuit Board) with USB functionality, one of the challenges […]

What is PCB Prototyping? PCB prototyping is the process of creating a physical representation of your electronic circuit design. It involves translating your schematic diagram into a layout that can be printed onto a board. This prototype allows you to test your design, verify functionality, and make any necessary revisions […]

What is a USB Cable Tester? A USB cable tester is a device that helps you determine whether a USB cable is functioning properly. It can detect issues such as broken wires, short circuits, and other common problems that can cause a USB cable to malfunction. USB cable testers come […]

Understanding SMD Components Surface Mount Devices, as the name suggests, are electronic components that are designed to be mounted directly onto the surface of a Printed Circuit Board (PCB). Unlike through-hole components, which require drilled holes for their leads to pass through the board, SMDs have small metal pads or […]

What is an AOI Test? An Automated Optical Inspection (AOI) test is a automated visual inspection process used to detect defects or anomalies in printed circuit board (PCB) assemblies. AOI tests use high-resolution cameras and image processing software to quickly scan and analyze PCBs for missing components, incorrect component placement, […]

Introduction to PCBA Drawing Requirements Printed Circuit Board Assembly (PCBA) is a crucial process in the manufacturing of electronic devices. It involves assembling various components onto a printed circuit board (PCB) to create a functional electronic system. To ensure the success of the PCBA process, it is essential to have […]
