Equipment Name: Chip Automatic Bonding and Assembly Equipment

The chip automatic bonding and assembly equipment is a core automation device in semiconductor packaging and microelectronics product manufacturing. It primarily achieves precise alignment, pressing, and assembly between chips (such as ICs, LED chips, sensor chips) and substrates (PCBs, ceramic substrates, glass substrates) or carriers through high-precision mechanical structures, vision positioning systems, and intelligent control algorithms. This replaces traditional manual operations, addressing issues like low precision, poor efficiency, and insufficient consistency in manual bonding. It is widely used in fields such as consumer electronics, automotive electronics, IoT, and medical electronics.

I. Core Functions and Workflow

The core objective of the equipment is to achieve full-process automation encompassing "precise positioning - stable attachment - quality inspection," with specific functions and procedures divided into the following 5 major stages:

Loading and Material Management

Equipped with multi-station loading modules (such as tray feeders, tape feeders, and vacuum pen loading mechanisms), it can automatically identify chip/substrate types and complete precise material grasping and conveying. Some high-end models support dual-material synchronous loading ("chip-substrate") and feature material shortage alerts and incorrect material detection to prevent waste.

High-Precision Visual Positioning

Equipped with a dual/multi-camera vision system (including industrial CCD cameras, high-magnification lenses, and light source modules), it performs image acquisition for both "chips" and "substrates":

Chip side: Identify chip pins, pad positions, contour deviations, and calculate compensation coordinates;

Substrate side: Locate pads, fiducial marks (Mark points), and correct substrate placement offsets;

Achieve micron-level positioning accuracy (typically ±1~5μm, with high-end models reaching ±0.5μm) through visual algorithms (such as template matching, edge detection), providing coordinate references for bonding.

Bonding process execution

The core actuator is a high-precision bonding head (equipped with vacuum suction pads, pressure control modules, temperature control units), executing corresponding processes based on different bonding requirements (such as bare chip bonding, flip chip bonding, COG glass bonding, etc.).

Pressure control: Achieves adjustable pressure output of 0.1~100N through piezoelectric sensors or servo motors to prevent excessive pressure from damaging chips/pads.

Temperature Control: For scenarios requiring thermocompression (such as anisotropic conductive film ACF bonding), the bonding head features a built-in heating module with a temperature control accuracy of ±1℃, supporting adjustment within the range of 50~250℃.

Bonding Speed: Adjustable according to material characteristics (e.g., flexible chips require low-speed and stable bonding) to ensure a process free from misalignment or bubbles.

Lamination and Curing (Optional)

Some bonding processes (such as those using UV adhesive or ACF adhesive) require subsequent lamination and curing: the equipment integrates lamination modules (e.g., roller lamination, flat plate lamination) or UV curing lamps to achieve "bonding - lamination - curing" integration, avoiding secondary misalignment during material transfer and enhancing bonding reliability.

Online Inspection and Sorting

After bonding, the equipment automatically inspects the bonding effect through a vision system or laser detection module:

Appearance inspection: Identify defects such as bubbles, offsets, pin disconnections, and adhesive overflow.

Performance testing (high-end models): Integrated resistance testing and continuity detection module to determine if the circuit is functioning properly after bonding.

Based on the inspection results, qualified products are conveyed to the next process while defective ones are automatically sorted into the waste bin, with the defect type recorded (to facilitate subsequent process optimization).

II. Core Advantages

Ultra-high Precision and Consistency

Utilizing visual positioning + servo drive technology, the alignment accuracy reaches the micrometer level, far surpassing manual alignment (manual accuracy is typically only around ±0.1mm). Moreover, the automated process eliminates human operational variations, increasing product yield by 10%~30% (for example, COG bonding yield for OLED screens improves from 85% to over 98%).

High-efficiency Mass Production Adaptation

Supports multi-station parallel operation (e.g., 2~4 bonding heads working simultaneously), with a single-machine hourly capacity of 300~1200 pieces (adjusted based on chip size), achieving 5~10 times the efficiency of manual labor. It can also integrate with front-end and back-end equipment (such as chip sorters, substrate cleaners, and finished product inspection machines) to form a fully automated production line.

Strong Process Compatibility

Modular design supports switching between various bonding processes: by replacing bonding heads, adjusting pressure/temperature parameters, and adapting different feeding modules, it can cover scenarios like bare dies (Die), flip chips (Flip Chip), COB (Chip on Board), COG (Chip on Glass), FPC flexible bonding, etc., and is compatible with chips and substrates ranging from 0.1mm to 50mm in size.

Intelligence and Traceability

Equipped with industrial software systems, it supports process parameter storage (such as pressure, temperature, and speed recipes for different products), production data statistics (capacity, yield, defect rate), and anomaly alerts (such as abnormal pressure or material shortages). Some models support MES system integration, enabling full-process data traceability to meet the quality control requirements of semiconductor manufacturing.

III. Typical Application Scenarios

Field of Semiconductor Packaging

Flip chip bonding for IC chips and PCB substrates (e.g., mobile processors, automotive MCU packaging), ensuring precise alignment between chip bumps and substrate pads through high-precision positioning to guarantee circuit conductivity; bonding of power semiconductors (e.g., IGBT) with ceramic substrates, requiring high-temperature lamination processes to ensure thermal performance and structural stability.

Display Panel Field

OLED/LCD Screen COG Bonding: The driver IC chip is bonded to the glass substrate, requiring strict control of pressure and temperature to prevent glass breakage or IC damage; Flexible OLED Screen FPC and Chip Bonding: Adapted to the characteristics of flexible materials, a low-speed and steady bonding process is employed to avoid creases or bubbles.   %%   Consumer Electronics and IoT Sector

Consumer electronics and the Internet of Things field

Miniature sensor chips for smartwatches and earphones (e.g., heart rate sensors, accelerometers) require ultra-precise positioning of sub-0.5mm chips for seamless integration. RFID tag chip-to-antenna substrate bonding demands high throughput and low-cost solutions, necessitating equipment with roll-to-roll continuous feeding capabilities.

Automotive Electronics Sector

Chip bonding for vehicle displays and radar modules must meet automotive-grade reliability standards (e.g., stability under high-temperature/vibration conditions), requiring equipment with enhanced pressure and temperature control precision. For automotive power modules (e.g., SiC modules), die-to-heatsink substrate bonding employs high-pressure lamination processes to optimize thermal dissipation efficiency.
