DAL Lab - EMI/EMC Test Facilities | HCLTech


HCLTech is one of the first companies in the private sector to plan for a complete product development environment and invest in EMI/EMC test facilities. It is important to ensure that any type of hardware product development complies with product specifications and regulatory standards. We are the first company to invest in an anechoic chamber for radiated emission and immunity tests. The test facility supports various domains like medical, IT, industrial, aero, and automotive. The same chamber is used to test for acoustic noise as well. Thermal imaging is another such service that helps design engineers locate and fix thermal hot spots in a product.

Industry Offerings

HCLTech has test facilities to support EMC testing of electronic assemblies for various domains. Most of the iterative tests, such as radiated emission, conducted emission, and ESD, can be carried out. This helps in testing and debugging the product, and this type of iterative testing is not provided by many labs. In addition, HCLTech can carry out acoustic noise measurement for products that have acoustic noise requirements, typically medical and IT products. Thermal imaging is a facility that captures the spatial thermal profile of a product and displays it as a color-coded image. This is a useful tool in locating hot spots and identifying heat dissipation issues. In a nutshell, the spread of EMC testing facilities ensures that various aspects of a product can be tested at a single facility.
