Theipi e khomarelang, eo hangata e tsejoang e le tepi ea ho khomarela, ke sehlahisoa se sebelisang lesela, pampiri, filimi le lisebelisoa tse ling e le thepa ea motheo.Sekhomaretsi se sebelisoa ka mokhoa o ts'oanang ho substrate e ka holimo, e sebetsoa hore e be lesela, ebe e etsoa ka coil bakeng sa phepelo.Theipi e khomarelang e na le likarolo tse tharo: substrate, sekhomaretsi, le pampiri e lokollang (filimi).

Mofuta oa substrate ke mokhoa o tloaelehileng oa ho arola litheipi tsa sekhomaretsi.Ho latela li-substrates tse fapaneng tse sebelisitsoeng, litheipi tsa sekhomaretsi li ka aroloa ka mekhahlelo e tšeletseng: tepi e thehiloeng pampiring, tepi e thehiloeng masela, theipi e thehiloeng filiming, tepi ea tšepe, tepi ea foam, le theipi e seng substrate.

Ho phaella moo, litheipi tse khomarelang li ka boela tsa aroloa ho latela katleho ea tsona le mofuta oa sekhomaretsi se sebelisoang.Ho ea ka katleho ea bona, tepi e khomarelang e ka aroloa ka tepi ea mocheso o phahameng, tepi e mahlakoreng a mabeli, tepi ea ho kenya letsoho, le tepi e khethehileng, joalo-joalo;Ho ea ka mofuta oa sekhomaretsi, sekhomaretsi se ka aroloa ka theipi e thehiloeng metsing, tepi e thehiloeng ka oli, tepi e thehiloeng ho solvent, tepi e chesang e qhibilihisang, le tepi ea tlhaho ea rabara.Theipi e khomarelang e na le mefuta e mengata ea lits'ebetso bophelong ba batho ba letsatsi le letsatsi le mesebetsing ea indasteri.Ka ntlafatso e tsoelang pele ea theknoloji ea tlhahiso ea theipi e khomarelang, mesebetsi e mecha e 'nile ea ntlafatsoa ka mokhoa o tsoelang pele bakeng sa tepi ea sekhomaretsi.E atolohile ho tloha ho tiisoa ha motheo, ho hokahanya, ho lokisa, ts'ireletso le mesebetsi e meng ho ea ho mesebetsi e fapa-fapaneng ea likarolo tse kang ho thibela metsi, ho kenya letsoho, conductivity, ho hanyetsa mocheso o phahameng, ho hanyetsa kutu, joalo-joalo.
