Advanced Sub-Micron Bonder
The FINEPLACER® sigma combines sub-micron placement accuracy with a 450 x 150 mm working area and bonding forces up to 1000 N.
The system is ideal for all types of precision die bonding and flip chip applications at chip and wafer level. This includes complex 2.5D and 3D IC packages, Focal Plane Arrays (i.e. image sensors), MEMS/MOEMS, and more.
Placing small devices on large substrates is made possible by the FPXvisionTM optical system design. With this alignment system, the smallest structures at the highest magnification can be viewed across the entire field of view. Moreover, FPXvisionTM introduces pattern recognition to a die bonder with manual alignment.
The FINEPLACER® sigma embraces all features of an assembly and development platform capable of handling an unlimited spectrum of applications and prepared for future technologies.
"We use the FINEPLACER® sigma for a variety of applications, ranging from simple chip-to-submount to complex module assemblies with very high accuracy requirements. Easy manual operation makes the system also an ideal fit for low-quantity research samples."

Applications & Technologies
With a broad range of supported applications and technologies, our die bonding systems are ready to tackle any application challenge in the industry. And as market requirements shift and new technologies emerge, their modular hardware and software architecture ensures maximum technological versatility over the entire service life.
Functions - Modules - Enhancements
Our die bonding solutions are as individual as our customers' requirements and offer a wide range of configuration options. In addition to the system's basic functions, which are part of the standard functional range, numerous process modules are available for each system, expanding the spectrum of applications. Retrofittable at any time, they enable additional die bonding technologies and processes either directly or as part of a module package. A selection of functional enhancements and accessory systems make daily work with the die bonder easier and help to make certain technology and process sequences even more efficient.
