I-1Cr13Al4 i-alloy ye-FeCrAl eBright Flat Strip/ i-Wide Strip yokusetyenziswa kwe-Resistors

I-Fecral Alloys kunye ne-Nickel-chromium alloys ziye zakhethwa ukuba zibe zizixhobo ezixhathisayo kwi-resistor edibeneyo ngenxa yokuba ii-alloys ze-nickel-chromium zine-resistivity ephezulu yombane esetyenziswa ngokubanzi kwii-resistors zefilimu ezibhityileyo [1, 2]. Ukumelana neshiti lefilimu ye-nickel-chrome alloy equlethe i-20% yechromium ingaba phezulu njenge-2-3 kilo ohms kwaye igcine uzinzo oluhle. Umlinganiselo wobushushu ongu-1 wokuxhathisa (TCR) kwi-alloy ye-nickel-chrome eninzi malunga ne-110 ppm/°C. Ngokudibanisa inani elincinci le-silicon kunye ne-aluminium nge-nickel-chromium, ukuzinza kweqondo lokushisa kuphuculwe ngakumbi.

Isicelo:

I-Resistors efakwe kwibhodi yocingo eprintiweyo iya kuba yinto evumela ukuba iipakethe ezincinci zibe nokuthembeka okuphezulu kunye nokusebenza kombane okuphuculweyo. Ukudibanisa ukusebenza kwe-resistor kwi-substrate ye-laminate ikhulula indawo ye-PWB esetyenziswe ngamacandelo ahlukeneyo, okwenza ukuba umsebenzi onyuswe wesixhobo ngokubeka amacandelo asebenzayo ngakumbi. Ingxubevange ye-nickel-chromium inokumelana nombane okuphezulu, okubenza ukuba basebenziseke kwizicelo ezahlukeneyo. I-Nickel kunye ne-chromium zifakwe kwi-silicon kunye ne-aluminium ukuphucula ukuzinza kweqondo lokushisa kunye nokunciphisa i-coefficient ye-thermal yokumelana. Umaleko ocekethekileyo wokumelana nefilimu esekwe kwi-nickel-chromium alloys ifakwe ngokuqhubekayo kwimiqulu yefoyile yobhedu ukwenza imathiriyeli yokufakwa kwe-resistor efakwe ngaphakathi. Umaleko wefilim obhityileyo ochasayo ophakathi kobhedu kunye ne-laminate unokubekwa ngokukhethayo ukwenza izichasi ezidityanisiweyo. Iikhemikhali ze-etching zixhaphakile kwiinkqubo zokuvelisa i-PWB. Ngokulawula ubukhulu be-alloys, amaxabiso okumelana nephepha ukusuka kwi-25 ukuya kwi-250 ohm / sq. zifunyenwe. Eli phepha liza kuthelekisa izinto ezimbini ze-nickel-chromium kwiindlela zabo zokudibanisa, ukufana, ukuphatha amandla, ukusebenza kwe-thermal, ukunamathela kunye nesisombululo se-etching.
