Used HERAEUS HEP 21 #9222844 for sale

HERAEUS HEP 21 is a burn-in test solution developed by HERAEUS Electronics for high-power integrated circuit manufacturing. It was designed to reduce process time and improve on-board wire placements. HEP 21 system is used to test the uniformity of high power integrated circuit (ICs). It assesses the ICs for uniformity, by providing an adaptable, highly-automated and efficient burn-in process. It is made up of a control cabinet, several burner cards, and heating boards. HERAEUS HEP 21 control cabinet includes a user-friendly touch screen where users can adjust the settings for each burn-in cycle, from power consumption, to cycle duration and temperature. It also includes several A/D and D/A conversion channels, multiple analog inputs and digital inputs and outputs. This component is connected to each burner card and to each heating board. On the burner cards, the user has the ability to choose either broad level power applied to the board or discrete current scaling. The heater boards provide the power to the integrated circuits. Power profiles can easily be customized and preset. The burn-in process begins with the application of DC or three-phase AC power to the heater boards for a preset amount of time and temperature. This allows any defects in power consumption to be identified. Once the temperatures reach their target level, HEP 21 system cycles the temperature in several controlled steps and monitors the current, voltage and power consumed. Once the preset cycle has been completed, the unit is turned off and the integrated circuit is tested for functionality. All data related to the burn-in process, such as the power consumption and temperature, is collected and recorded in a log for further analysis. Overall, HERAEUS HEP 21 is an efficient burn-in test solution used in the manufacturing of high-power ICs. It ensures the integrated circuits are uniformly and carefully tested, reducing overall process time and costs and improving on-board wire placements.
