1Cr13Al4 Bright Flat Strip 5 - 310mm Upamhi FeCrAl Alloy waya
Nzvimbo Yekushandisa: Inoshandiswa zvakanyanya muchoto cheindasitiri, midziyo yemumba, choto cheindasitiri, simbi, michina, ndege, mota, mauto uye mamwe maindasitiri anogadzira zvinhu zvinodziya uye zvinopokana.
Resistors akaiswa mune yakadhindwa wiring board ichave inogonesa miniaturizing mapakeji ane kuvimbika kwepamusoro uye nekuvandudzwa kwemagetsi. Kubatanidza iyo resistor performance mu laminate substrate inosunungura nzvimbo yePWB inopedzwa ne discrete components, zvichiita kuti kuwedzerwa kwechishandiso chishande nekuiswa kwezvimwe zvinoshanda zvinoriumba. Nickel-chromium alloys ane yakakwirira yemagetsi resistivity, iyo inoita kuti ishande kushandiswa mumhando dzakasiyana dzekushandisa. Nickel uye chromium zvakasanganiswa nesilicon nealuminium kunatsiridza kugadzikana kwetembiricha uye kudzikisa thermal coefficient yekuramba. Imwe firimu yakatetepa inodzivirira yakavakirwa pane nickel-chromium alloys yakaiswa nguva dzose pamapumburu emhangura foil kugadzira zvinhu zveyakamisikidzwa resistor application. Iyo yakatetepa firimu resitive layer yakamisikidzwa pakati pemhangura uye laminate inogona kusarudzwa yakarongedzwa kuti iite discrete resistors. Iwo makemikari etching akajairika muPWB maitiro ekugadzira. Nekudzora ukobvu hwema alloys, shizha kuramba kukosha kubva pa25 kusvika 250 ohm/sq. zvinowanikwa. Iri bepa rinofananidza maviri nickel-chromium zvinhu mune yavo etching nzira, kufanana, simba rekubata, mashandiro ekupisa, adhesion uye etching resolution.
