The level of cleanliness maintained dunng the assembly of the component by the manufacturer can easily be compromised unless car, is also exercised during wbeoquent operations, such am post-test handling, pemang, packaging and shpang. Precautions are sliP essential at these points to ensure that contamination does rick degrade the perfoimanoe of a component such that it tails to meet the purchasems expec1allons In addelon, topics such as traming, the provision of appropriate procedures and control over the erwironnient are equaty enportent. 7.2 TrainIng Effective bairing at each step 01 the product production end debmery prooses is essential to mi,Wnize the introduction 01 contamination, Persons involved with the manufacture, assembly. testing. packaging, storage and inspection ci flied power components should be educated in the basics of contamination coremoL Tralnmg should Include en appreciation 01 the effects of contamination, as well as instruction in pertorming specific tasks, It pereorwiel do not understand the damaging effects of contamination, th.y may not fOlLOW the prescribed procedures 7.3 WorkIng environment The workplac. should b designed so that drty processes such me...
