Semiconductor packaging has extremely high requirements for dispensing precision and consistency. The application of the Dispensing System in this field represents the highest level of automated fluid dispensing equipment, playing an irreplaceable role in chip underfill, wire bond protection, and package sealing.
Core Applications: I. Chip underfill with epoxy resin between chip and substrate using jet valves at 200 times/second with ±2% precision for gaps below 0.1mm; II. Wire bond protection coating along bond lines; III. Package sealing along chip edges; IV. Thermal material application on high-power chip backsides.
Technical Requirements: Positioning precision ±0.01mm; Dispensing precision 0.5nl level; Non-contact jetting avoiding chip damage; Visual positioning for automatic chip location recognition; Cleanroom environment Class 1000+.
As semiconductor manufacturing develops toward smaller sizes and higher density, the precision application of the Dispensing System will become even more critical. As a high-end application field of automated fluid dispensing equipment, the Dispensing System in semiconductor packaging represents the industry's highest technical standards.
Second Intelligent automotive dispenser machine not only excels in hardware equipment, but also makes breakthroughs in technological innovation. The company has launched a number of fully automatic dispensers, such as FPC-NTC-CCS dispenser, SEC-E380 desktop automatic dispenser, etc., which have won wide recognition in the market for their high precision, high efficiency and high stability. These machines are equipped with advanced CCD visual positioning system, which realises precise identification and positioning of product position through high-definition camera and image processing algorithm, effectively avoiding errors caused by human factors. At the same time, the equipment also has an automatic correction function, which can adjust the position and angle of the dispensing head in real time to ensure the consistency and stability of the dispensing effect.
