Core Modules

Thanks to modulization design of AVA ASD products. It is very easy to build a new ASD base on AVA ASD modules. Manufactures with R&D capabilities can use AVA core modules like HSSD and Aspiration modules, design the interface circuits and a housing to develop an new ASD model with little efforts. Companies without or with limited R&D capabilities can use most or all the modules and design just the housing to develop a new ASD product.

The following are the introduction of modules to build an AVA product.
