The CMTS – Compact Multicell Test System is a multipurpose test machine designed for precision, efficiency and footprint optimization by accommodating a large number of test positions while maintaining functionality comparable to other standard test systems.

The station functions as an automatic pick & place system, enabling easy placement and removal of test modules based on test requirements and production demands. 

Its modular design allows for a simple line layout reconfiguration, by removing some test cells (modules) without interrupting the production line. Another main advantage of this concept is space saving: the vertical modular configuration allows for the integration of a maximum of 12 modules without the need to increase the production floor footprint. 

Controlar MTM – Multicell Test Modules are incorporated within the CMTS and have the capacity to execute multiple functions, enabling the integration of diverse functional tests. 

The modules are designed with multicell capability, allowing for two Device Under Test (DUT) per tray, according to the specific product and functionality.

Due to the high complexity and numerous configurations, a modular design approach was employed for ordering and assembling different modules. Thus, smaller reusable modules can be utilized across various tray designs. This facilitates easier development of complex modules for different products and functionalities.
