Indawo yesicelo: Isetyenziswe ngokubanzi kwiziko lemizi-mveliso, izixhobo zombane zasekhaya, izitya zokushishisa, oomatshini, oomatshini, inqwelo moya, emkhosini kunye nezinto zokuxhathisa.
Abahlali abangeniswe kwibhodi eprintiweyo eprintiweyo iya kuba yinkqubo yephakheji encinci ngokuxhomekeka okuphezulu kunye nokuphuculwa kokusebenza kombane. Ukudibanisa ukusebenza kwakhona kwi-lamonite Free ikhupha indawo ye-PWB yendawo ye-PWB etyiwayo ngamacandelo agqityiweyo, ukuvumela ukusebenza kokusebenza kwempahla ngokubekwa kwezinto ezisebenzayo. I-Nickel-Chromium Altiays inayo inkohliso yombane, eyenza ukuba babe ngabasebenzi ukuze basetyenziswe kwizicelo ezahlukeneyo. I-nickel kunye neChufreium zabelwe i-silicon kunye ne-aluminium yokuphucula uzinzo lobushushu kwaye inciphise i-thermal caorance yokungasebenzi. I-facient yefilimu ecekeceke esekwe kwi-Nickel-Chromium Alwile ifakwe ngokuqhubekayo kwiRolls ye-foil ye-forper yokusebenza kwezicelo ezifakelweyo. I-firwsing yefilimu yefilimu ye-swerwhed yesandwich phakathi kobhedu kunye nelamote inokufakwa ngokukhethekileyo ukuba isebenze kakuhle. Iikhemikhali ze-etching zixhaphakile kwiinkqubo zemveliso ye-PWB. Ngokulawula ubukhulu be-altrays, amashishini okuxhathisa amaphepha ukusuka kwi-25 ukuya kwi-250 ohm / sq. zifunyenwe. Eli phepha liza kuthelekisa izixhobo ezimbini ze-chromium-chromium kwiindlela zabo ze-etching, iyunifomu, ukuphatha amandla, ukusebenza kwe-thermal, ukunamathela kunye nesisombululo.
