In today’s electronics manufacturing industry, one of the most commonly used surface treatment processes for PCBs is electroless nickel immersion gold (ENIG). Due to its excellent flatness, high...
The Impact of Solder Joint Microstructure on Reliability
The internal microstructure of solder joints, as well as the intermetallic compound (IMC) structure at the solder-PCB substrate interface, determines...
Comparison of MVC’s Reflow Soldering Capacity
MVC refers to the most vulnerable component (MVC) during reflow soldering, such as liquid dielectric aluminum electrolytic capacitors, connectors, DIP...
In the printed circuit board (PCB) assembly process, wave soldering plays a crucial role in component fixation. With continuous upgrades in manufacturing technology and increasing environmental awareness,...
As modern electronic products evolve towards lighter weight, higher speed, and greater efficiency, every step of the manufacturing process follows the same principle, and printed circuit board (PCB) assembly...
Visual Inspection: Visual inspection is a critical step in the surface mount soldering quality control process. It involves inspecting solder joints and components on the circuit board to identify defects...
Tombstone Effect
The tombstone effect, also known as the Manhattan effect or bridging effect, is a common reflow soldering defect. It occurs when one end of a surface-mount component (usually a chip resistor...
Printed Circuit Boards (PCBs) are one of the most important technologies to emerge in the 20th century.
With the continuous advancement of global technology, their use has become increasingly rapid, permeating...
Through-hole (PTH) components are typically wave soldered onto PCBs. However, for assembling PCBs with PTH components, there is another option—through-hole reflow soldering.
