1. Visual Inspection The first and most basic method of checking for soldering defects is visual inspection. This process involves carefully examining the soldered joints and components on the PCB Board using the naked eye or a magnifying glass. Some common defects that can be detected through visual inspection include: […]

1. Bridging What is Bridging? Bridging, also known as solder bridges, occurs when excess solder creates an unintended connection between two or more adjacent pads or traces on a PCB. This defect can lead to short circuits and cause the device to malfunction. Causes of Bridging Excessive solder paste application […]

What is PCB Prototyping? PCB prototyping is the process of creating a physical printed circuit board (PCB) based on a design, for the purpose of testing and validation before mass production. A PCB Prototype allows designers and engineers to verify that their circuit design works as intended in the real […]
