The Hectronic support team performs functional testing, stress testing and temperature cycling to identify problems and perform corrective actions. There are six fully equipped work stations in the RMA lab with individual test systems for every product and product version.
These resources are a necessity for fast and accurate response, according to Erik Flodin, Support Manager. He seizes the opportunity to highlight another aspect of his work.
– My goal is always to return a working product as fast as possible and a rich description of the problem by the customer is always highly appreciated in order to succeed.
Hectronic runs a separate, fully ESD protected, RMA/support lab with it’s own, independent computer network. The facilities are planned in detail to meet the needs of the support team.
– The many 220 V electric sockets are all connected to the same single phase conductor. If the computer board power supply and the test rig is not connected to the same phase conductor there may appear differential voltages that damage sensitive components, typically in the power supply and interfaces.
The testing procedures include verification of for instance power distribution, EEPROM programming, wireless connectivity and Ethernet port data communication. If fully operational at normal temperatures it’s time to increase the load, stress the boards and systems to increase the working temperature and put the unit to the test over a prolonged period of time.
– We use a large set of tests to verify functionality and check components. Lead by the information from the customer we are able to focus our efforts on a subset of relevant test cases.
