1Cr13Al4 FeCrAl alloy Bright Flat Strip / Wide Strip rau Resistors Siv

Cov Khoom Siv Fecral thiab Nickel-chromium alloys tau raug xaiv los ua cov khoom siv resistive rau embedded resistor vim tias nickel-chromium alloys muaj cov hluav taws xob resistivity siab uas siv dav rau cov zaj duab xis nyias resistors [1, 2]. Cov ntawv tsis kam ntawm nickel-chrome alloy zaj duab xis uas muaj 20% chromium tuaj yeem siab txog 2-3 kilo ohms thiab tseem tswj tau qhov ruaj khov zoo. Qhov kub thiab txias coefficient 1 ntawm kev tsis kam (TCR) rau cov khoom siv nickel-chrome yog li 110 ppm / ° C. Los ntawm kev sib xyaw me me ntawm silicon thiab txhuas nrog nickel-chromium, qhov kub thiab txias ruaj khov tau txhim kho ntxiv.

Daim Ntawv Thov:
Cov resistors uas muab tso rau hauv lub rooj tsavxwm luam tawm yuav yog ib qho cuab yeej rau kev ua kom cov pob khoom me me nrog kev ntseeg siab dua thiab kev ua haujlwm hluav taws xob zoo dua. Kev koom ua ke ntawm cov resistor functionality rau hauv lub laminate substrate ua rau thaj chaw PWB uas cov khoom sib cais siv, ua rau muaj kev ua haujlwm ntawm cov khoom siv ntau dua los ntawm kev tso cov khoom siv ntau dua. Nickel-chromium alloys muaj cov hluav taws xob resistivity siab, uas ua rau lawv siv tau rau ntau yam kev siv. Nickel thiab chromium yog alloyed nrog silicon thiab txhuas los txhim kho qhov kub thiab txias thiab txo qhov thermal coefficient ntawm kev tiv thaiv. Ib txheej nyias nyias resistive raws li nickel-chromium alloys tau tso rau ntawm cov ntawv ci tooj liab kom tsim cov khoom siv rau kev siv resistor embedded. Cov txheej nyias nyias resistive sandwiched ntawm tooj liab thiab laminate tuaj yeem xaiv etched los tsim cov resistors sib cais. Cov tshuaj rau etching yog ib txwm muaj nyob rau hauv cov txheej txheem tsim khoom PWB. Los ntawm kev tswj cov tuab ntawm cov alloys, cov nqi tiv thaiv ntawv los ntawm 25 txog 250 ohm / sq. tau txais. Daim ntawv no yuav piv ob cov khoom siv nickel-chromium hauv lawv cov txheej txheem etching, kev sib xws, kev tswj hwm lub zog, kev ua haujlwm thermal, kev nplaum thiab kev daws teeb meem etching.
