Solder Bridging An excess conductive pathway formed by solder between wires. The bridging phenomenon is a type of soldering problem in PCBs, referring to the excessive solder that causes PCB pads to connect together. Unlike tombstone defects, bridging is not easily detected. However, it can cause fatal damage to the PCB. Tombstone refers to a … Read more
V-cut During PCB splicing, the V-shaped dividing line between two single boards and between a single board and the process edge forms a “V” shape; it is called V-cut because it is broken and separated after soldering. Purpose of V-cut The main purpose of designing V-cut is to facilitate operators in separating the boards after … Read more

In the process of electrical design, certain design choices must be made. One example is the design of USB Type-C connectors using bridge connectors. In this case, the overall thickness of the PCB is limited by the thickness of the bridge connector. Historically, the standard PCB thickness is 0.063 in (1.57 mm). Before the advent … Read more
FPC, also known as flexible printed circuit board, has a significantly different PCBA assembly and soldering process compared to rigid circuit boards. Due to the insufficient hardness of the FPC boards, which are relatively soft, it is impossible to complete the basic SMT processes such as printing, mounting, and reflow without using a dedicated carrier … Read more
PCB design is both a science and an art. There are many technical specifications related to trace width, layer stacking, schematics, etc. However, when it comes to the artistic aspects of component placement in PCB design, the issue becomes interesting. In fact, there are very few restrictions on component placement, and there are no “absolutely … Read more
The reliability testing and failure analysis of PCB / PCBA proceed hand in hand; when design pressures reach their limits, thorough inspection and analysis are needed to determine their failure modes. Some of these tests and potential failure causes are handled by manufacturers, as they may arise during the bare board manufacturing process, while other … Read more
When learning about PCB design, we often encounter two very similar concepts: PCB and PCBA. We know that PCB stands for Printed Circuit Board, but what about PCBA? What is the relationship and difference between them? About PCB PCB stands for Printed Circuit Board, which is a circuit board made using electronic printing technology. It … Read more
Click the above“Mechanical and Electronic Engineering Technology” to follow us In the vast ocean of the electronic world, the terms PCB, PCBA, and SMT serve as coordinates on a nautical chart, guiding us to understand the transformation of electronic products from concept to reality. Today, we will explore these three key technologies that bring electronic … Read more
PCB, known as Printed Circuit Board, is an important electronic component, serving as the supporting body for electronic components and the carrier for electrical connections between them. It is referred to as a “printed” circuit board because it is made using electronic printing technology. In the research process of larger electronic products, the most fundamental … Read more
