MELSS provides new battery testing solutions for EVs
MEL Systems and Services (MELSS) launched battery testing equipment, dispensing robot and connection validation soldering system in the recently- concluded Automotive Testing Expo 2018 in Chennai. Primarily, MELSS offers battery testing equipment for electric vehicles. Some of the testing equipment are brought from Taiwan. The company has designed and built various types of Power Supply ATEs which are built to cater to the test and product qualification needs of the various power supply design and manufacturing organisations. As the scope of electric vehicles are increasing, the automotive companies started focusing on the components and testing solutions required for the electric vehicles. MELSS provides testing solutions for battery, XY Dispensing robot and soldering system.
In the battery testing process, before the batteries are fitted into the vehicle, battery’s individual modules are tested using the testing machine which is imported from Chroma, Taiwan. The machine simulates the condition of the battery in various parameters and tests the efficiency and modules of the battery with greater accuracy. MELSS supply a fluid dispensing solution for wherever the precision dispensing is required. The dispensing robot machine helps in PCB and in engine block where it dispenses the fluid for sealing purposes. It is used wherever high precision and sealing required. The Soldering and Dispensing Solutions are brought from the brand Metcal and Techon.
The company spokesperson said that “automated dispensing robots are easy to programme, simple to operate and compatible with all valve types and controllers. These are designed and configured specifically for fluid dispensing applications. The dispensing robots offers unsurpassed value in automated precision fluid dispensing. It provides total control over fluid placement, from beads, arcs and circles to repeated timed dots.”
Metcal is the brand that MELSS uses for the connection validation soldering. Metcal soldering stations have led the way with SmartHeat technology. SmartHeat senses the thermal load and instantly delivers Power on Demand directly to the joint. The embedded, self-regulating heater delivers the right amount of power based on the requirements of the solder joint. This provides a fast, safe and repeatable process with no calibration required. The intermetallic compound thickness is critical in the formation of a solder joint. Connection Validation (CV) evaluates the quality of the solder joint by calculating the intermetallic compound formation and provides closed loop feedback to the operator. CV provides feedback to the operator via the LED light ring integrated in the hand-piece. It takes the risk associated with the variables involved in the soldering activity and removes the success and failure determination of a good solder joint out of the hands of the operator. CV complements the skill of the operator to judge the quality of a solder joint by introducing an objective method of evaluating solder joint quality. This systemic and objective approach provides repeatability and a measurable standard to the soldering process.
“For identifying the manufacturing process-related defects, we have a strong preference for in-circuit testers as they provide the highest possible fault detection among all the technologies. Modern generation in-circuit testers include other test technologies as part of testers, like boundary scan tests, MDA functions etc. Functional tester is the gatekeeper that allows only fully working boards to be shipped out of an assembly line. The tester looks at the whole PCB and not at individual components. It simulates the functions of the boards and compares it to the expected operation of the board as per the design with allowance for minor design variations,” he said.
