ENVIRONMENTAL STRESS SCREENING
It Helps Electronics Manufacturers To Detect Defective Products And Production Flaws… Finding These Failures Before The Product Reaches The Customer Yields Better Quality And Lower Warranty Expenses. BEL Products Are Used By The Para Military Forces So All Equipments Requires More Reliable And Better Quality. Associated Military Terminology Includes An Operational Requirements Document (Ord) And On-going Reliability Testing (Ort).This Environmental Stress Is Done With The Help Of These Four Steps .
How These Functions Works
Under This Process Each Manufacturing Unit Temperature Varies From Very Low To Extreme High Temp(-39⁰c To 89⁰c).. Because All Components (Radio, Aircraft Parts, Etc ) Works At The Extreme Conditions.
Vibration tests:-
Vibration Testing Is Accomplished By Introducing A Forcing Function Into A Structure, Usually With Some Type Of Shaker. So When Product Transported From Industry To The Functioning Area It Remains In Sound Condition..
Flexibility tests:-
A Unit That Exhibits Any Sign That A Part Is Stressed Beyond Its Design Limit (Cracked Circuit Boards, Loose Connectors And/Or Screws, Bent Clamps And/Or Screws, Worn Parts, Etc.) Is Considered To Have Failed
