Huagmeginly yog ib zaj duab xis nyias tiaj tiaj tiv thaiv rau PCB raug. Nws yog ib txheej resistor tsim los ntawm ib qho txheej txheem etching thiab txheem pcb luam ntawv. Lub resistor tso cai cov tsim qauv kom ua kom zoo rau kev siv chaw ntawm PCB saum npoo. Cov khoom siv Ohmega no yog siv los ua lub xeev dawb paug, muab cov qauv tsim qauv los daws cov kev sib tw hauv hluav taws xob uas xav tau passive resistors.
OhmegAgly muaj ntawm ib zaj duab xis nyias muaj alloy txheej thiab cov txheej txheem tooj liab tso rau ntawm lub tooj liab ntawv ci. Ib qho ntxiv, cov ntaub ntawv no muaj cov txheej txheem sib txawv nyias txheej tiv thaiv tsis tau. Cov ntaub ntawv PCBA tuaj yeem muab cov khoom siv rau cov khoom siv dielectric.
Ntau cov ntawv thov tau sib txuamhmegosply txij li xyoo 1970. Dhau li ob peb xyoo dhau los, cov khoom siv no tau pom tau tias ntev kev ntseeg tau thiab kev ruaj khov. Ib qho ntxiv, nws tau dhau los ua lwm txoj hauv kev zoo rau lwm cov khoom tiv thaiv embedded. Lub Ohmeganply Desistor yog tsim rau ntau yam ntawm cov ntawv thov siab.
Tsis tas li ntawd, OhmegAply suav nrog Nickel phosphorus (nip) alloy. Thaum lub sijhawm SMT Patch Cov txheej txheem ntawm cov khoom no, engineers electrodeposited kwv yees li 1. 00 micron ntawm alloy mus rau tus tooj liab ntawv ci. Tooj liab ntawv ci yog electrodeposited. Cov khoom siv ohmega no muaj nyob rau hauv 50 ohms rau ib lub square, 10 ohms ib lub saws nrog kev thev taus ntawm}% thiab}}}}%, ntsig txog.
Ohmeginly muab nqi thiab tsim cov txiaj ntsig. Tshem tawm cov neeg tiv thaiv no pab cov engineers kom paub cov txiaj ntsig txuag nqi. Ntau dua cov ceev ceev txhais tau ntau dua cov nqi txuag tau. Cov khoom siv ohmega no siv nyob rau hauv ntau cov kev siv. Qee qhov kev lag luam kev lag luam OEMS, xws li Apple, ua kom ua ntej fiber ntau thiab boeing, sib xyaw cov khoom no rau hauv lawv cov khoom.
Qhov loj ntawm cov resistor thiab hom dielectric cov ntaub ntawv txiav txim siab qhov nyiaj ntawm lub zog thov. Cov hwj huam raug nplua rau Ohmegaxinly muaj txog 1\/8 ntawm watt. Txawm li cas los xij, kev siv cov laminate cov ntaub ntawv nrog cov khoom kub siab dua tuaj yeem txhim kho qib qib no.
