♦ What Is SMT Assembly?

SMT Assembly (Surface Mount Technology Assembly)​​ is a modern method of mounting electronic components directly onto the surface of a printed circuit board (PCB). It is the most widely used PCB assembly technique today, replacing traditional through-hole technology (THT) in most applications due to its efficiency, precision, and ability to support miniaturized and high-density designs.

♦ What Is SMD?

An ​​SMD​​ is an electronic component designed specifically for surface mounting (SMT). These components have small metal pads or terminations instead of long leads.

​​Types of SMD Components:​​

♦ ​​Common Challenges in SMT/SMD Assembly​:​​

​​

• ​​Solder Bridging​​ (unwanted connections between pads)
• ​​Tombstoning​​ (one end of a component lifts during soldering)
• ​​Misalignment​​ (components shift before reflow)
• ​​Voiding in BGA Soldering​​ (air gaps in solder joints)

​​Solutions:​​
✔ ​​Proper stencil design​​ (for accurate solder paste application)
✔ ​​Reflow profile optimization​​ (temperature control)
✔ ​​AOI & X-ray inspection​​ (for defect detection)
