INFINITE pushes the boundaries of miniaturisation

“Miniaturisation to the near-atomic level is pushing Moore’s Law, which states that the number of transistors per chip area doubles every two years, to its physical and economic limits,” said Dr. Gary Widdowson, Chief Technology Officer at ASMPT Semiconductor Solutions. “As a result, further steps in miniaturisation are shifting more and more toward making advances in of component packaging. With our highly innovative INFINITE bonder, manufacturers will be optimally prepared for this challenge.”

The INFINITE bonder achieves a throughput rate of up to 18,500 UPH with a placement accuracy of ±20μm @ 3σ in standard mode and ±12.5μm @ 3σ in high-precision mode. In its standard version, the machine can process dies with areas ranging from 0.2 × 0.2mm to 9 × 9mm and thicknesses ranging from 0.075 to 1mm with a bonding force ranging from 0.196 to 29.43N. The maximum substrate size is 300 × 100mm.

Intelligent features save time and maximise quality

To create the best possible conditions for the application of adhesives, the INFINITE bonder first uses its iSense function to inspect each placement area for bumps and warps. All the user needs to do during the setup phase is to specify the epoxy resin’s parameters, the desired bond line thickness, and the fillet height to be achieved. All other parameters such as the processing speed, pattern, and application height, are automatically determined by the ASMPT AI. The machine optimises the application of the adhesive over the course of a few test steps with touchless measurements and feedback. Most setups are completed within 30 minutes.

With the intelligent iTouch feature, the INFINITE bonder can maintain the programmed bonding forces with exceptional accuracy. This enables the reliable processing of even very thin dies made of highly sensitive materials such as silicon carbide (SiC) and gallium nitride (GaN). The precisely defined and monitored bonding force is ideal for silver-sintering paste and keeps the fillet height within the defined window despite varying process parameters.

The INFINITE bonder supports various packaging types, such as BGA, LGA, SiP, MEMS, or QFN. The high-precision machine can be deployed in many demanding production areas for products like 5G components, high-performance AI chips, safety-critical components for the automobile industry or the medical sector, and last but not least for high-quality and highly miniaturised consumer products.
