Crystal's vital contribution was subjected to a battery of tests: tests at the R D lab stage, field tests and finally user tests. It is a matter of greater pride to the group that is electronics came through all these stages with flying colours.
Another prestigious ARDE project in which Crystal was involved was the design and manufacture of electronically timed fuse timers, programmable through an external  programmer device. This application serves many needs across the defense sector. Crystal was involved in the design of the distribution box for the multi-barrel rocket launcher.

QUALITY IS INSEPARABLE FROM PRODUCTION
 
People associated with the growth of the Crystal Group over the years recall that there was a time when its products were being openly sold as "imported" goods in the Bombay Market. This could also be interpreted as a reflection of the group's humble beginnings. Which did not allow for a sizable advertising and marketing budget to establish a distinctive brand name. But it is also a clear testament of the high quality standards that the group has set, attained and most importantly maintained.
Components are then subjected to the dry heat chamber test one sample of each batch before they go for final inspection.characteristic which is adoption of the modular mode of construction a mode that allows easy design adaptability as well as better checking as well as after sales service

   Apart from fulfilling its stated objective of designing and manufacturing high quality products in the low-tech end of electronic, the Crystal Group has done some prestigious assignments for leading organizations, especially in the defense sector. These assignments, setting new standards in the particular sector of the Indian electronics components industry, have won accolades for the Crystal Group's R & D capabilities and stringent manufacturing and design standards.

One such project was the Crystal Group's intensive involvement, spread over a number of years in the Armament Research and Development Establishment's (ARDE) 'Gold Fish Project' for the Indian navy. The Crystal Group designed and produced, to ARDE's fullest satisfaction the entire electronics that went into this crucial anti-mine sweeper device. The design was a complex of over 10 function modules, power packs a motherboard and a framework for housing the different modules all connected to the motherboard  with the help of 64 pin euro connectors.

 
A brief overview of the manufacturing set-up and processes shows how this has been achieved simply put, quality is inseparable from any of the process in the Crystal Group's way of working.It begins with procurement of materials from genuine and genuine source. All in coming components are subjected to the cyclic test over 40 degrees Celsius to 55 degrees Celsius. Then rigorous functional testing takes place and rejection are simply thrown away.

Assembly takes place in a fully anti-static environment and testing is done with various instruments like frequency counters and frequency generators. Soldering is done only via the wave soldering method a quality check by it self. After preliminary testing at the PCB level step, step-by-step testing is done at different levels.

The design and assembly segments of Crystal's set up are themselves arrangements in a modular fashion. The workshop is fully equipped for sheet metal fabrication. Like wise the assembly section is fully equipped with lead cutting / bending machines and jig fixtures for PCB assembly. The testing equipment includes storage oscilloscopes and a range of Multimeters.

In addition to this setup which is backed by the strength of experienced and competent personnel, Crystal has the proven ability to design digital logic based circuits along circuits and low-end discrete logic and function circuits. crystal has also proven in the sphere of medium complexity circuits.

Its chief strength is of course in the product engineering department. The Crystal characteristic of distributing circuits into modules with ideal  physical placement allows overall ease of operation and maintenance. So user friendly are Crystal's products that the group is often asked to give engineering consultancy and guidance.
