Here’s a sneak peak into Silizon’s manufacturing floor and its innovative electronics contract manufacturing services (ECMS)
By Baishakhi Dutta
Silizon offers complete solutions in EMS, ranging from SMT, SKD and CKD to in-house software programming and mobile manufacturing, with a focus on quality, competitiveness and timely execution.
How the journey started
Ronak Sonthalia, director, Silizon Technologies, relates a brief history of the company: “My father has been the main driving force behind this firm. It is his vision that has moulded the company into what it is today. He started off a decade back with his own company, named Raunak Electrovision, at Bhagirath Palace in Delhi. This firm primarily dealt with the trading of electronic components. Interestingly, before setting foot in Delhi, he had his own trading company in Assam. After shifting his base to Delhi, he first focused on importing components from China. Then, one day, we decided that it was a good time to set up our own manufacturing unit. That marked the beginning for the manufacture of components. And this year, in February, my brother and I opened our own EMS company at Noida, called Silizon Technologies LLP.”

Currently, it manufactures mobile phones for different brands, and plans to expand its reach to include yet more mobile manufacturing companies. Apart from being the only mobile PCB manufacturer in the Indian market, Silizon also develops PCBs for other high-demand consumer electronic products including LED TVs, set-top boxes and DTH. Components for signal meter cards and energy meters are also a part of the firm’s vast product portfolio. The company makes a significant contribution in the manufacture of radar system components, telecom units, solar charge controllers and solar drivers. Another interesting fact is that Silizon is presently manufacturing for certain government companies as well, details of which are confidential.

Quality parameters
The company has experienced and trained manpower that has wide exposure in the design, production, quality assurance and testing processes. Detailed procedures and work instructions are irreplaceable constituents of a comprehensive quality management system, leading to well-defined functional and reliability testing. A few major quality parameters that Silizon follows are:

Goals and the journey forward
The government’s ‘Make In India’ initiative has been a major reason behind Silizon jumpstarting its domestic manufacturing operations for the Indian market. In a market flooded with PCBs imported from China by mobile manufacturers, being the only company in India to locally manufacture PCBs is an impressive achievement. Today, Silizon aims to extend its mobile manufacturing business a step further. It plans to set up a complete mobile assembly unit. With the set-up phase now completed, Silizon is all set to manufacture PCBs for mobile phones in bulk.
With its state-of-art infrastructure and well thought-out business strategy, it is evident that Silizon is going to expand and flourish well in the electronics market. The company also has ambitious plans of offering mobile chip manufacturing services for smartphones after February 2017.
