API 5L guud ahaan waxa ay tilmaamaysaa dhuumaha xadhkaha leh ee API 5L, tuubada khadka ayaa ah in lagu qaado saliidda, uumiga iyo biyaha dhulka laga soo saaro oo la geeyo shirkadaha warshadaha saliida iyo gaaska iyada oo la sii marinayo tuubada khadka.Dhuumaha khadka waxaa ka mid ah tuubo aan fiicneyn iyo bir alxan leh.Cidhifyadu waxay leeyihiin cidhifyo siman, cidhifyo dun leh iyo darafyada godka;hababka isku xirka waa alxanka, isku xirka isku xirka, xiriirka godka, iwm.

| Ku filan (R, N, Q ama M) ee darajooyinka PSL2, waxa iska leh darajada birta |
1. Habka ugu muhiimsan ee wax-soo-saarka tuubada birta ah ee kulul ee duuban (habka kormeerka ugu weyn):
Diyaarinta iyo kormeerka tuubada banaan → tuubo kuleyl banaan → daloolin → tuubo rogroga → birta dib u kululaynta → daawaynta kulaylka go'an (la dhimay) dhexroorka → daawaynta kulaylka △ → dhamaystirka tubada toosinta → dhamaystirka → kormeer (aan burburin, jireed iyo kiimiko, Kormeerka Taiwan) → bakhaarka
2. Habka ugu muhiimsan ee wax soo saarka ee tuubooyinka birta ee qabow-duuban (la sawiray):
Diyaarinta billet → Saliid qajaar → duubid qabow (sawir) → daawaynta kulaylka → toosin → dhammayn → kormeer
