Introduction

In the fast-paced world of semiconductor manufacturing, precision marking plays a crucial role in ensuring the identification and traceability of various components. Specifically, for small-size chip packaging like QFN (Quad Flat No-Lead) packages, precision marking becomes even more critical due to the compact nature of the chips. To meet these demanding requirements, Han’s Laser has developed an advanced automatic laser marking machine specifically designed for QFN packages. This cutting-edge machine incorporates high-precision motion systems, a visual positioning system, and a range of automated functions to deliver accurate and efficient marking. In this article, we will explore the features and benefits of the automatic laser marking machine for QFN packages.

1.Precision Marking for Small-Size Chip Packaging

The automatic laser marking machine is designed to meet the high-precision marking requirements of small-size chip packaging, such as QFN packages. These packages are widely used in the semiconductor industry due to their compact size and enhanced thermal dissipation capabilities. However, their small form factor presents challenges for achieving accurate and legible markings. The automatic laser marking machine overcomes these challenges by providing precise and consistent marking on the small-size chip packaging, ensuring readability and traceability.

2.High-Precision Motion System and Visual Positioning

To achieve the required precision in marking, the automatic laser marker incorporates a high-precision motion system. This system enables smooth and accurate movement of the laser head, ensuring precise positioning of the marking on the QFN package. The visual positioning system complements the motion system by providing real-time visual feedback and alignment during the marking process. The combination of these two systems ensures precise and reliable marking results on the small-size chip packaging.
