Modular IC Chip Placement Equipment: The Perfect Fusion of Efficiency and Precision
In the field of semiconductor packaging and testing, the precise placement of IC chips is a critical step in
ensuring the smooth operation of subsequent packaging and testing processes. Traditional manual place
ment methods are not only inefficient and unable to meet the demands of large-scale production, but also
prone to chip damage or contamination due to operational errors. The emergence of modular IC chip
placement equipment has completely changed this situation. Through highly integrated mechanical stru
ctures, advanced vision recognition systems, and intelligent control algorithms, it achieves automatic chip
picking, detection, and precise placement, bringing revolutionary improvements in production efficiency to
the semiconductor industry.
I. Core Module Components
1. Mechanical Motion Module
The equipment adopts high-precision linear motors and a dual-actuator design, combined with a servo
motor-driven ball screw and synchronous belt transmission system, ensuring fast response and precise pos
itioning of the X, Y, and Z axes. This design allows the equipment to maintain a repetitive positioning accura
cy of ±0.05mm at high speeds, meeting the micron-level placement requirements of chips. The modular
mechanical structure facilitates maintenance and upgrades, allowing users to flexibly adjust the motion ra
nge and speed according to production needs.
2. Vision Recognition System
The equipment is equipped with multiple sets of high-resolution industrial cameras, including an upper visi
on positioning system and a lower vision flying camera system. The upper vision system is responsible for
identifying the initial position and orientation of the chip, while the lower vision system performs secondary
confirmation during the chip picking process to ensure absolute accuracy of the placement position. Throu
gh advanced image processing algorithms, the equipment can automatically distinguish the front and back
sides of the chip, identify pin directions, and adapt to different specifications of chips (such as QFP, BGA, SOP
, etc.), offering strong compatibility.
3. Intelligent Suction Module
Using multiple ZR motion suction heads, each suction head is equipped with an independent pneumatic
control system that can automatically adjust the suction force according to the chip size and weight. The su
ction head structure is designed with anti-static and anti-damage functions to ensure that no scratches or el
ectrostatic damage are caused to the chip surface during high-speed picking. The quick-change design of the
suction heads allows the equipment to adapt to different shapes and sizes of chips, improving the versatility
of the equipment.
4. Vibration Feeding and Receiving Module
The equipment integrates a flexible vibratory feeder and an automatic receiving system. The vibratory feeder
arranges bulk chips in an orderly manner through precise vibration and guides them to the pick-up position
via a feeding guide rail. The receiving system automatically handles the placement of empty trays and the
collection of full trays, achieving full automation from feeding to receiving, reducing manual intervention
and improving production efficiency.
II. Equipment Advantages and Features
1. High Efficiency and High Precision
The equipment adopts a design that allows for picking up multiple products at once, completing the placem
ent of 8,000-12,000 chips per hour, far exceeding manual operation. At the same time, through visual recogn
ition and precise motion control, it ensures the accuracy and consistency of chip placement, reducing rewor
k and waste caused by placement errors.
2. Modularity and Scalability
All functional modules of the equipment use standardized interface designs, making it easy for users to expa
nd or upgrade functions according to production needs. For example, users can increase the recognition
accuracy and picking capacity of the equipment by adding additional vision cameras or suction heads.
3. Intelligent Control and Easy Operation
The equipment is equipped with a graphical operation interface and an intelligent control system, supporti
ng multi-recipe parameter saving and quick switching, making it easy for operators to get started. At the sam
e time, the equipment has self-diagnosis and alarm functions, which can promptly detect and handle abnor
mal situations, ensuring the stability and safety of the production process.
III. Application Prospects
The modular IC chip placement equipment, with its high efficiency, high precision, and modular design, has
become an indispensable key equipment in the semiconductor packaging and testing process. With the con
tinuous advancement of semiconductor technology, chip sizes are becoming smaller and integration levels
are becoming higher, placing increasingly stringent demands on the accuracy and speed of placement equip
ment. The modular design allows the equipment to quickly adapt to these changes, meeting new production
needs through simple module upgrades. In the future, with the deep integration of artificial intelligence and
the Internet of Things technology, IC chip placement equipment will become more intelligent and networ
ked, bringing greater production efficiency improvements and cost optimization opportunities to the semic
onductor industry.
