Merritronix was incorporated on October 14, 1988 as ‘Merritronix Private Limited’, a private limited company. Thereafter, the company was converted into a public limited company pursuant to a resolution passed by the shareholders at an Extraordinary General Meeting held on January 06, 2025, and consequently the name of the company was changed to ‘Merritronix LTD.’ 

The company is an Electronics Systems Design and Manufacturing services (ESDM) company specializing in high-reliability, mission-critical electronic assemblies and systems for defence, aerospace, telecommunications, Rapid Prototyping for design houses OEMs, Engineering services Companies and specialized industrial electronics. It is primarily engaged in business-to-business (B2B) electronic manufacturing services, encompassing component sourcing, printed circuit board (PCB) assembly, system integration, testing, box-build solutions and delivery of finished electronic products - executed to the quality standards required by India's strategic defence and aerospace programmes. This integrated manufacturing and design support capability enables the company to serve industries that require reliable and performance-oriented electronic systems.

A key part of the manufacturing process is Surface-Mount Technology (SMT), which involves assembling electronic components directly onto the surface of printed circuit boards (PCBs) using automated placement systems and controlled reflow processes. Its SMT capabilities support the use of advanced and miniaturized components required in defence, aerospace and industrial electronic systems. The largely automated nature of the SMT process - including solder paste printing, automated component placement and controlled reflow soldering - enables consistent quality and precision. The company derives its revenue from a diversified set of business segments, namely job work, turnkey manufacturing/build-to-print, obsolescence management (including obsolete component procurement and engineering support) and trading sales.
