Namhlanje siza kuthetha ngendlela esifanele sikhethe ngayo ubungakanani obufanelekileyo be-rivet,
Xa ufuna iirivethi, eyona nto ibalulekileyo kukukhetha ububanzi D beqokobhe lerivethi kunye nobude L beqokobhe lerivethi. 1. Jonga umngxuma wendawo esiyisebenzisayo. Ngokubanzi khetha ububanzi obuncinci kancinci kune-aperture. Ukuba ububanzi berivethi bukhulu kakhulu, buya kuba njalo. Ngenxa yoko, irivethi ayinakufakwa. Ukuba ububanzi berivethi buncinci kakhulu, buya kubangela ukuyekelela. Ngokubanzi, ubungakanani obuncinci obuyi-0.1-0.2MM bufanelekile ngakumbi. 2. Jonga ubukhulu berivethi. Ubukhulu bendawo yokusetyenziswa kufuneka bube ngaphantsi kobude betyhubhu yerivethi. Iiparameter zingathelekiswa netheyibhile elandelayo ukukhetha iinkcukacha zerivethi.
Umzekelo, umngxuma yi-3.3MM kwaye ubukhulu yi-3MM. Kwitheyibhile sibona ngokucacileyo ukuba kufuneka sikhethe u-D 3.2MM-L7MM
I-Formula D*L=3.2*7MM iirivethi zesinyithi ze-aluminiyam
