Avanoa Talosaga: E masani ona faʻaaogaina i totonu o le ogaumu fale gaosimea, meafale fale, ogaumu alamanuia, metallurgy, masini, vaalele, taʻavale, militeli ma isi pisinisi e gaosia ai elemene faʻavevela ma elemene tetee.
Resistors fa'apipi'i i totonu o se laupapa uaea lolomi o le a avea ma fa'aagaaga mo le fa'aitiitiina o afifi ma maualuga atu le fa'atuatuaina ma fa'aleleia le fa'atinoga o le eletise. O le tu'ufa'atasia o le fa'atinoga o le tetee i totonu o le laminate substrate e fa'asa'olotoina ai le vaega o le PWB o lo'o fa'aaogaina e vaega tu'ufa'atasi, e mafai ai ona fa'ateleina le fa'aogaina o masini e ala i le tu'uina atu o vaega e sili atu ona malosi. Nickel-chromium alloys e maualuga le malosi o le eletise, lea e mafai ai ona faʻaaogaina i le tele o talosaga. O le nikeli ma le chromium o loʻo tuʻufaʻatasia i le silikoni ma le alumini e faʻaleleia ai le mautu o le vevela ma faʻaititia ai le faʻaogaina o le vevela o le tetee. O se vaega manifinifi e tetee atu i ata e fa'avae i luga ole nickel-chromium alloys ua fa'aauau pea ona teuina i luga o ta'avale apamemea e fai ai se mea mo fa'aoga fa'apipi'i. O le ata manifinifi vaega tetee sanuisi i le va o le kopa ma le laminate e mafai ona togitogia filifilia e fai ai ni tetee eseese. O vaila'au mo le etching e taatele i le gaosiga o le PWB. E ala i le faʻatonutonuina o le mafiafia o uʻamea, faʻamaufaʻailogaina o laupepa mai le 25 i le 250 ohm / sq. e maua. O lenei pepa o le a faʻatusatusa mea e lua nickel-chromium i a latou metotia faʻapipiʻi, tutusa, faʻaogaina o le eletise, faʻaogaina o le vevela, faʻapipiʻi ma le fofo o le etching.
