Malo Ogwiritsira Ntchito: Amagwiritsidwa ntchito kwambiri mu ng'anjo ya mafakitale, zipangizo zapakhomo, ng'anjo yamakampani, zitsulo, makina, ndege, magalimoto, asilikali ndi mafakitale ena omwe amapanga zinthu zotenthetsera ndi zinthu zotsutsa.

Ma resistors omwe ali mu bolodi losindikizidwa la mawaya adzakhala othandizira kupanga ma phukusi ang'onoang'ono okhala ndi kudalirika kwakukulu komanso magwiridwe antchito abwino amagetsi. Kuphatikiza magwiridwe antchito a resistor mu laminate substrate kumamasula malo a PWB omwe amagwiritsidwa ntchito ndi zigawo zosiyana, zomwe zimapangitsa kuti chipangizocho chigwire ntchito bwino poika zigawo zogwira ntchito kwambiri. Ma alloy a nickel-chromium ali ndi mphamvu zambiri zamagetsi, zomwe zimapangitsa kuti zikhale zothandiza kugwiritsidwa ntchito m'njira zosiyanasiyana. Nickel ndi chromium zimasakanizidwa ndi silicon ndi aluminiyamu kuti ziwongolere kukhazikika kwa kutentha ndikuchepetsa mphamvu ya kutentha. Gawo lochepa loletsa filimu lochokera ku ma alloy a nickel-chromium layikidwa mosalekeza pa mipukutu ya zojambulazo zamkuwa kuti apange zinthu zogwiritsira ntchito resistors. Gawo lochepa loletsa filimu lomwe lili pakati pa mkuwa ndi laminate likhoza kudulidwa mosankha kuti lipange ma resistors osiyana. Mankhwala oletsa ndi ofala kwambiri popanga PWB. Powongolera makulidwe a ma alloy, ma resistance a pepala kuyambira 25 mpaka 250 ohm/sq. amapezeka. Pepalali lidzayerekeza zipangizo ziwiri za nickel-chromium mu njira zawo zophikira, kufanana, kugwiritsa ntchito mphamvu, kutentha, kumatira, ndi kukana kuphikira.
