1Cr13Al4 FeCrAl alloy Bright Flat Strip/ Wide Strip yekushandiswa neResistors

Fecral Alloys uye Nickel-chromium alloys zvakasarudzwa kuti zvive zvinhu zvinodzivirira resistor yakapinzwa nekuti nickel-chromium alloys dzine resistivity yakakwira yemagetsi iyo inoshandiswa zvakanyanya kune thin film resistor [1, 2]. Kuramba kwepepa re nickel-chrome alloy film ine 20% chromium kunogona kusvika 2-3 kilo ohms uye kuchiri kuramba kwakagadzikana. Tembiricha coefficient 1 of resistance (TCR) ye bulk nickel-chrome alloy inenge 110 ppm/°C. Nekubatanidza silicon nealuminium shoma ne nickel-chromium, kugadzikana kwetembiricha kunovandudzwa zvakanyanya.

Kushandiswa:
Ma resistors akaiswa mubhodhi remagetsi rakadhindwa achava mukana wekuita kuti mapakeji ave madiki uye akavimbika uye mashandiro emagetsi ari nani. Kubatanidza mashandiro e resistor mu laminate substrate kunosunungura nzvimbo yePWB inodyiwa nezvikamu zvakasiyana, zvichiita kuti mashandiro emudziyo awedzere nekuisa zvikamu zvinoshanda zvakanyanya. Nickel-chromium alloys ine resistivity yakakwira yemagetsi, izvo zvinoita kuti zvive nyore kushandisa mumabasa akasiyana-siyana. Nickel nechromium zvinosanganiswa nesilicon nealuminium kuti zvivandudze kugadzikana kwetembiricha uye kuderedza coefficient yekupisa. Layer tete resistive yakavakirwa pa nickel-chromium alloys yakaiswa nguva dzose pamarolls e copper foil kugadzira chinhu chekushandisa embedded resistor. Layer tete resistive film rakaiswa pakati pe copper ne laminate rinogona kuchekwa nenzira yakasarudzwa kuti rigadzire ma resistors akasiyana. Makemikari e etching anowanikwa mumaitiro ekugadzira PWB. Nekudzora ukobvu hwe alloys, sheet resistance values ​​kubva pa25 kusvika 250 ohm/sq. inowanikwa. Pepa iri richaenzanisa zvinhu zviviri zve nickel-chromium mumaitiro azvo ekutema, kufanana, kubata simba, kushanda kwekupisa, kunamira uye kugadziriswa kwekutema.
