Advanced Sub-Micron Bonder
The FINEPLACER® femto 2 is a fully-automated die bonder with a placement accuracy of 0.3 µm @ 3 sigma that offers unrivaled flexibility for prototyping & production environments.
A complete machine enclosure allows very demanding applications in a controlled environment. Fully protected from external influences, the system stands for highly stable assembly processes with the focus on maximum yield.
The new generation of the femto platform adds numerous innovations to the proven technical basis. This includes the cutting-edge FPXvisionTM. Combined with a refined pattern recognition, this all-new Vision Alignment System opens up a new dimension of application flexibility and accuracy. IPM Command, the fully revamped FINEPLACER® operating software, supports a consistent, ergonomic and clearly structured process development.
Depending on the requirements, the modular FINEPLACER® femto 2 can be individually configured and retrofitted at any time to support new applications and technologies. This makes the system a perfect tool and reliable companion as applications migrate from product development to production. It covers the entire workflow of inspection, characterization, packaging, final test and qualification in semiconductor, communications, medical and sensor technologies.
"The FINEPLACER® femto 2 has enabled our company to realize higher throughput automation of our high accuracy flip chip bonding operations. As our high reliability opto-electronic transceiver business is expanding, this has helped us to satisfy our customer’s growing needs."

Applications & Technologies
Functions - Modules - Enhancements
Our 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. Retrofittable at any time, they enable additional 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 machine easier and help to make certain technology and process sequences even more efficient.
Use different tools or tool tips, automatic exchange in process.
Direct contact heating from the top with chip specific tool design to apply temperature from the chip side. E.g. used for thermocompression, gluing or ACA bonding
Ensures safe handling of components from GelPak®, VR trays, waffle packs or tape holders.
Used to pick up components with the placement arm directly from blue tape. Supports snap rings and wafer frames.
Used to flip components prior to face-down assembly.
Integration of dispensing systems for applying adhesive, flux, solder paste or other pasty material. Various supported types like time-pressure, volume and jet dispensers.
The “Known Good Die Testing” allows chip probing/ testing prior to the bonding process.
Creates an inert or reactive (CH2O2) process atmosphere. Used to reduce and prevent oxidation during soldering (e.g. eutectic or indium bonding). Add-on for Substrate Heating Modules.
Innovative digital beam splitter with two HD cameras provides highest optical resolution across a large field of view.
Used to handle and rotate substrates up to 360° independently from the bonding tool.
Allows automatic focus setting of component and substrate as well as height measurements.
Allows sensing of heights by means of Laser triangulation for measuring purposes.
Allows ultra-fast heat cycles du to an integrated high power laser source
Software tool to recognize various alignment marks. Used to control the position or alignment between component and substrate.
Creates an inert or reactive (H2N2) atmosphere in an enclosure. Used to prevent or reduce oxidation during soldering or bonding.
