Ce produse din cuar\u021b de \u00eenalt\u0103 puritate sunt utilizate \u00een procesele de circuite integrate? Care sunt cerin\u021bele privind con\u021binutul de impurit\u0103\u021bi?<\/p>\n\n\n\n
Produsele din cuar\u021b de \u00eenalt\u0103 puritate utilizate \u00een mod obi\u0219nuit \u00een procesele de circuite integrate includ plachete de cuar\u021b, cristale de cuar\u021b, tuburi de cuar\u021b \u0219i ferestre de cuar\u021b.<\/p>\n\n\n\n
Pentru plachetele de cuar\u021b, con\u021binutul de impurit\u0103\u021bi trebuie s\u0103 fie extrem de sc\u0103zut, \u00een general \u00een intervalul de p\u0103r\u021bi pe miliard (ppb) sau mai mic. Acest lucru se datoreaz\u0103 faptului c\u0103 plachetele sunt supuse la temperaturi ridicate, presiuni, acizi puternici, baze puternice \u0219i alte condi\u021bii \u00een timpul procesului de fabrica\u021bie, iar impurit\u0103\u021bile pot afecta propriet\u0103\u021bile electrice \u0219i fiabilitatea plachetelor.<\/p>\n\n\n\n
Pentru cristalele de cuar\u021b, con\u021binutul de impurit\u0103\u021bi trebuie, de asemenea, s\u0103 fie c\u00e2t mai sc\u0103zut posibil, de obicei \u00een intervalul ppb. Cristalele de cuar\u021b sunt utilizate pentru a produce componente precum oscilatoare \u0219i filtre, iar impurit\u0103\u021bile pot afecta stabilitatea frecven\u021bei \u0219i performan\u021ba acestora.<\/p>\n\n\n\n
Pentru tuburile de cuar\u021b \u0219i ferestrele de cuar\u021b, con\u021binutul de impurit\u0103\u021bi trebuie s\u0103 fie relativ sc\u0103zut, \u00een general \u00een intervalul de p\u0103r\u021bi pe milion (ppm). Tuburile \u0219i ferestrele din cuar\u021b sunt utilizate la fabricarea echipamentelor de vid \u0219i a dispozitivelor optice, iar impurit\u0103\u021bile pot afecta propriet\u0103\u021bile lor fizice \u0219i optice.<\/p>\n\n\n\n
\u00cen rezumat, cerin\u021bele privind con\u021binutul de impurit\u0103\u021bi pentru produsele din cuar\u021b de \u00eenalt\u0103 puritate utilizate \u00een procesele de circuite integrate sunt foarte stricte, iar impurit\u0103\u021bile trebuie minimizate pentru a reduce impactul acestora asupra performan\u021bei dispozitivului.<\/p>","protected":false},"excerpt":{"rendered":"
