SESAME 1000 Laser Decapsulator

Laser Decapsulator

SESAME 1000 Laser Ablation System has been specifically designed for effective decapsulation of IC packages, containing either a single die or multiple dice.

At the system's heart is a Nd:YAG 1064nm diode-pumped LASER, which is housed inside a chamber to provide full protection from LASER radiation, in compliance with applicable VBG 93, DIN EN, and CE  standards.

The integrated optical vision system provides constant sample monitoring. A previously-taken X-Ray or an Acoustic Microscope image can be superimposed onto the SESAME's live component image to provide additional data for successful decpasulation.

SESAME 1000's intuitive software incorporates drawing tools for definition of the material to be removed which can be drawn onto the component image. The actual amount of material removed can be measured by camera focal-depth techniques or by using an external mechanical indicator.

Prior to the LASER ablation process, the component is scanned by a red pilot LASER. The system's firmware controls all process parameters such as power, frequency, scan speed and focal distance. All process parameters can be stored by specific component and product family for easy recall.

Following laser ablation, the die surface can be revealed with a low temperature wet etch with RAPIDETCH, or with plasma.

 

NOTE: SESAME Technology incorporates mutual Patents and IP developed by CNES and DIGIT CONCEPT SA. ULTRA TEC is the representative for North America. Customers in other territories should contact  DIGIT CONCEPT directly.
