Hluav Taws Xob Hluav Taws Xob Yav Tom Ntej Yog Qhov Kev Xaiv Zoo rau Kev Coj Ua thiab Kev Ntsuas
Muaj ntau qhov kev nce qib hauv kev lag luam hluav taws xob uas txhim kho txhua hnub. Cov khoom siv hluav taws xob yog tsim los nrog kev ua tau zoo thiab raug los ntawm cov kws tshaj lij tshwj xeeb. Muaj ntau ntau yam cuam tshuam hauv kev tsim cov khoom siv hluav taws xob. Hlau, windings, resistors thiab lwm yam yog cov khoom siv hauv kev npaj cov khoom siv hluav taws xob. Tab sis ib qho tseem ceeb uas tau siv hauv txhua lub cuab yeej yog cov khoom siv hluav taws xob. Cov khoom siv hluav taws xob no yog tsim los ntawm cov nyiaj, txhuas thiab lwm yam khoom. Cov pastes no yog rhuab thiab siv los tswj kev sib txuas ntawm cov khoom siv hluav taws xob / thermal / dielectric kev twb kev txuas. Cov khoom siv hluav taws xob yog qhov tseem ceeb hauv cov khoom siv hluav taws xob. Kev siv ntau dua tuaj yeem ua rau luv luv thiab yog tias siv me me ces yuav muaj kev sib txuas tsis zoo. Kuj tseem muaj ntau hom pastes muaj nyob hauv khw. Ib tug yuav tsum xyuas kom meej coj ib tug zoo zoo ntawm muab tshuaj txhuam los xyuas kom meej ib tug muaj zog kev twb kev txuas.
Cov khoom siv hluav taws xob no yog siv rau kev sib txuas thermal lossis hluav taws xob tom qab cua sov lawv raws li lub rooj tsav xwm hluav taws xob. Feem ntau cov pastes no yog cov nyiaj pastes vim nyiaj muab cov txiaj ntsig zoo li malleable, ductile, thiab cov khoom muag muag heev. Cov no feem ntau yog siv nyob rau hauv soldering. Muaj ntau ntau hom pastes muaj raws li lawv cov khoom ua haujlwm: -
* Conductive paste - Tus neeg xyuas pib muab tshuaj yog ib qho nplaum uas txuas hluav taws xob sib txuas ua ke. Cov no yog siv ntau heev nyob rau hauv cov laug cam uas thaiv tsis tau. Muaj ntau yam khoom siv hluav taws xob muaj xws li Ag paste, Ag / Pd paste, Au paste, Pt paste, wolfram paste uas tuaj yeem siv rau hauv ntau daim ntawv thov xws li buzzer, stainless hlau substrate electrode, coj ceramic Circuit Court, tuab zaj duab xis Circuit Court thiab raws li kev nkag siab. element thiab lwm yam… Nrog rau ntau daim ntawv thov loj cov pastes no nyob rau hauv siab thov.
* Resistor paste - Lub resistor muab tshuaj yog qhov tseem ceeb heev nrhiav pom. Nws yog npaj xws li ib txoj kev uas nws yog thermally conductive thiab hluav taws xob insulated. Nws feem ntau yog siv los ua ib qho interface rau cov dab dej kub thiab cov khoom siv cua sov. Lub ntsiab muaj pes tsawg leeg ntawm cov pastes yog ag, pd thiab RuO2. Lub resistor pastes yog siv nyob rau hauv nti resistor, resistor, substrate resistor thiab qis kub cua sov teb. Muaj ob pawg ntawm resistor muab tshuaj txhuam: lub zog tiv thaiv paste thiab tuab zaj duab xis resistor muab tshuaj txhuam.
* Dielectric muab tshuaj txhuam - Lub dielectric muab tshuaj txhuam yog hluav taws xob rwb thaiv tsev thiab tuaj yeem tiv taus qhov hluav taws xob siab. Nws kuj yog siv los ua cov roj nplua nyeem thiab yog li hu ua silicon roj. Cov pastes no pom daim ntawv thov hauv stainless hlau insulating, stainless hlau cua sov board thiab alumina substrate tuab zaj duab xis Circuit Court ntau txheej insulating ua haujlwm.
* Lub Rooj Tswjhwm Saib Xyuas - Muaj ntau yam khoom siv cua sov uas muaj xws li ceramics cua sov phaj, iav ceramics cua sov version, stainless hlau cua sov phaj thiab mos substrate cua sov phaj.
Cov pastes no tau pom ntau daim ntawv thov hauv kev kho vaj tse, chaw kuaj mob thiab kev tsim khoom siv. Muaj ntau tus kws tshaj lij uas tsim cov khoom zoo tshaj plaws ntawm Ag paste. Nrog kev txhim kho thiab txhim kho kev txawj ntse, cov kws tshaj lij no tau tsim kho cov khoom siv hluav taws xob zoo heev. Nyob rau lub sijhawm no uas siv cov khoom siv hluav taws xob tau txhawb nqa los ntawm cov khoom siv hluav taws xob, kev tsim cov khoom siv no xav tau cov khoom siv hluav taws xob.
