Temperature Control for Stress Tests in TV Decoders

Objectives: To show the development of a solution for the temperature control of a quarter of stress tests where the equipment is subjected to extreme temperature conditions (controlled) for a short time and to ensure that the integrated circuits are not defective or the welding points are crystallized. Methods/Analysis: For this purpose, a temperature control is designed using the LM35 low cost commercial temperature sensor and RS485 serial communication between a PSoC5LP and the LabVIEW program for information processing and system control. Findings: To obtain good results, one must be certain about the maximum temperatures at which the equipment can be subjected, also know the most adverse temperature conditions to which an electronic equipment may be subjected in real life and thus avoid the damage of these so that it produces more electronic garbage that every year, due to the demand and the technological advance, is greater. Improvements: The designed control system can be implemented in a low cost computer such as a Raspberry Pi making the system much more versatile.
