Cerintele extreme ale industriei semiconductorilor

Camerele de vid utilizate in echipamentele de procesare a semiconductorilor sunt printre cele mai pretentioase piese prelucrate mecanic. Tolerantele geometrice extrem de stranse, geometriile complexe multi-fata si necesitatea mentinerii unui vid inalt perfect impun capabilitati de prelucrare de exceptie.

Aliajul de aluminiu aeronautic AL7075 este materialul standard pentru camerele de vid semiconductor datorita:

  • Raport rezistenta/greutate superior
  • Proprietati mecanice excelente la temperaturi variabile
  • Prelucrabilitate buna care permite finisaje fine
  • Compatibilitate cu mediile de inalt vid
