Automated Optical Inspection (AOI): Principles, Defects, and PCB Applications
What Is Automated Optical Inspection (AOI)? Automated Optical Inspection (AOI) is a machine-based inspection method that uses high-resolution cameras, controlled lighting, and image-processing software to automatically detect visual defects on printed circuit boards (PCBs). It is widely used in PCB fabrication and PCB assembly to inspect components, solder joints, and conductor patterns without physical contact. By comparing captured images with design data or reference models, AOI systems can quickly......

What Are the Different Types of SMT Tests in PCB Assembly
Full-fledged electronics solutions that aim to minimize size and space use surface mount components. Although the SMT components function similarly to the TH, they are generally chosen due to their small size and compatibility with both side assemblies. When developing for mass manufacturing, cost is also the primary issue because of their low cost, which allows us to use them in large quantities. Due to their small size, inspection methods and repair operations are now more challenging. A product is ......

What is a Bed of Nails Test Fixture
Testing is important when it comes to electronics product manufacturing. It is the most crucial yet deciding the working condition of a product. There are many testing procedures a product wants to go through. When working with an assembly company the testing may take a lot of time to reduce the manpower and time there should be a set of instructions to follow. For this the BED OF NAILS test is designed, so that we can make a type a zig and test the prototypes directly by connecting the testing points......

Electrostatic Discharge (ESD): The Hidden Threat to Electronics
It's possible your next electronic device could be deployed in an area where it is exposed to high voltages or static electricity. In these cases, a system’s vulnerability to ESD should be determined through testing and simulation. Electrostatic Discharge (ESD) is the sudden transfer of static electricity from one object to another. This phenomenon occurs when there is a difference in electrical potential between two surfaces, leading to an abrupt discharge of energy. The charge can be accumulated par......

PCB Failure Analysis: Understanding the Causes and Solutions
Printed circuit board (PCB) failure analysis is vital for finding and resolving issues causing electronics to stop working. PCBs are highly complex and feature numerous layers of circuitry that interact with one another, hence it can be difficult to understand why something is not working. A damaged component may bring down the entire system. By doing a failure analysis, makers can make PCB designs more reliable and stop problems from happening again. This article goes into detail about why PCB failur......

Understanding PCB Tombstone: Causes and Solutions
In the ever-evolving landscape of PCB (Printed Circuit Board) and PCBA (Printed Circuit Board Assembly), manufacturers face an array of challenges, from intricate designs to precise assembly processes. Among these challenges, PCB tombstoning stands out as a particularly vexing issue. Tombstoning occurs during the reflow soldering process when one end of a surface-mounted component lifts off the pad, resembling a tombstone. This seemingly minor defect can have major repercussions, jeopardizing the func......
