Nyob rau hauv txoj kev loj hlob sai ntawm niaj hnub electronic technology, lubsiab - zausKev sib txuas lus teb tau muab tso rau hauv cov kev cai nruj heev rau kev ua haujlwm ntawm cov ntaub ntawv pcb. PTFE siab- cov ntaub ntawv zaus, nrog rau lawv cov yam ntxwv zoo, tau dhau los ua qhov kev xaiv zoo tshaj plaws rau kev ua haujlwm siab - zaus pcb thiab tau thawb kev lag luam mus rau theem tshiab ntawm kev txhim kho.
Cov txiaj ntsig tshwj xeeb ntawm PTFE siab - cov ntaub ntawv zaus
Qhov laj thawj tseem ceeb vim li cas PTFE siab- cov ntaub ntawv zaus sawv tawm ntawm ntau cov ntaub ntawv pcb yog lawv cov khoom zoo heev dielectric. Piv nrog rau cov ntaub ntawv ib txwm muaj, PTFE muaj qhov tsis tshua muaj hluav taws xob tsis tshua muaj hluav taws xob tsis tu ncua, uas ua rau cov teeb liab kom muaj kev ntseeg siab thaum sib kis, txo cov teeb liab poob thiab qeeb. Nyob rau hauv siab - zaus daim ntawv thov scenarios xws li 5G kev sib txuas lus thiab satellite kev sib txuas lus, PTFE cov ntaub ntawv uas tsis tshua muaj dielectric tsis tu ncua yuav xyuas kom meej ceev thiab meej teeb liab kis tau tus mob, zoo heev txhim kho kev sib txuas lus zoo thiab efficiency.
Lub caij no, PTFE muaj tshuaj lom neeg ruaj khov thiab kub kub ua haujlwm. Txawm hais tias ntsib cov tshuaj lom neeg ib puag ncig lossis kev ua haujlwm hnyav xws li kub thiab av noo, luam ntawv Circuit Court boards ua los ntawm PTFE siab- cov ntaub ntawv zaus tuaj yeem ua haujlwm ruaj khov, muab cov khoom lav rau lub sijhawm ntev - cov khoom siv txhim khu kev qha. Cov yam ntxwv no tau ua rau PTFE siab- cov ntaub ntawv zaus siv dav hauv thaj chaw xws li aerospace, tub rog thiab kev tiv thaiv uas yuav tsum muaj kev ntseeg siab.
Cov teeb meem thiab cov teeb meem hauv PTFE siab - cov khoom siv zaus pcb ua
Txawm li cas los xij, qhov tshwj xeeb ntawm lub cev thiab tshuaj lom neeg ntawm PTFE siab - cov ntaub ntawv zaus kuj tau coj ntau yam teeb meem rau kev ua pcb. PTFE cov ntaub ntawv muaj ib tug mos mos kev ntxhib los mos thiab yog nquag deformation thaum lub sij hawm drilling thiab milling txheej txheem, uas yuav tsum tau ua cov cuab yeej muaj siab precision thiab stability. Nyob rau tib lub sijhawm, kev xaiv cov cuab yeej txiav thiab kev tswj cov txheej txheem tsis tseem ceeb heev. Txhawm rau kom tsis txhob muaj cov khoom deformation, cov cuab yeej txiav tshwj xeeb yuav tsum tau siv thaum lub sijhawm ua haujlwm qeeb qeeb, thiab cov txheej txheem ua tiav txhua lub sijhawm yuav tsum tau tswj nruj me ntsis. Piv txwv li, rau 0.8mm tuab PTFE ntawv, tsuas yog ob daim tuaj yeem muab tso rau hauv qhov drilling.
Lub zog qis ntawm cov khoom siv PTFE ua rau tsis zoo adhesion nrog conductors xws li tooj liab ntawv ci, uas yog ib qho teeb meem nyuaj nyob rau hauv cov txheej txheem tsim pcb. Txhawm rau txhim kho qhov adhesion ntawm ob, kev kho tshwj xeeb yog feem ntau yuav tsum tau nyob rau saum npoo ntawm PTFE cov khoom, xws li kev kho ntshav plasma lossis tshuaj etching, kom ntseeg tau tias cov ntawv ci tooj liab tuaj yeem ruaj khov rau PTFE substrate, yog li ua kom muaj kev ntseeg siab ntawm kev sib txuas hauv Circuit Court.
Tsis tas li ntawd, cov khoom siv PTFE muaj cov coefficient siab ntawm thermal expansion. Thaum qhov kub hloov pauv, pcb muaj qhov hloov pauv qhov loj me thiab kev ntxhov siab, uas yuav cuam tshuam rau kev teeb tsa thiab kev ua haujlwm ntawm cov khoom siv hluav taws xob. Yog li ntawd, hauv kev tsim thiab tsim cov txheej txheem, nws yog ib qho tsim nyog yuav tsum xav txog tag nrho cov thermal expansion qhov tseem ceeb, txo cov kev ntxhov siab los ntawm kev tsim qauv tsim thiab kev ua kom zoo dua qub, thiab xyuas kom meej tias pcb tuaj yeem ua haujlwm ruaj khov hauv qhov sib txawv ntawm qhov kub thiab txias.
Technological thiab txheej txheem innovation los daws cov teeb meem kev ua haujlwm
Txhawm rau kov yeej cov kev cov nyom ntawm PTFE siab- cov khoom siv zaus pcb ua, kev lag luam niaj hnub tsim kho tshiab hauv tshuab thiab cov txheej txheem. Nyob rau hauv cov txheej txheem drilling, siab - nrawm thiab siab - precision CNC drilling tshuab yog siv, ua ke nrog tshwj xeeb nyuaj alloy laum khoom. Los ntawm kev tswj xyuas qhov tsis zoo xws li kev ceev thiab pub tus nqi, cov khoom deformation thiab burr tiam tuaj yeem txo tau zoo. Nyob rau tib lub sijhawm, plasma tu lossis tshuaj etching kho ntawm lub qhov phab ntsa tom qab drilling tuaj yeem tsis tsuas yog tshem tawm cov khib nyiab thiab impurities ntawm lub qhov phab ntsa, tab sis kuj txhim kho qhov roughness ntawm phab ntsa ntawm lub qhov thiab txhim kho lub zog sib txuas ntawm cov tooj liab txheej thiab lub qhov phab ntsa thaum kho tom qab metallization.
Ntau yam kev tshaj lij tau tsim los rau kev sib koom ua ke ntawm cov ntawv ci tooj liab thiab PTFE substrate. Piv txwv li, los ntawm kev siv cov nplaum tshwj xeeb thiab siab - kub thiab siab - lub tshuab laminating siab, lub zog adhesion ntawm tooj liab ntawv ci thiab substrate tau txhim kho zoo thaum ua kom ntseeg tau tias kev ua haujlwm ntawm PTFE cov khoom tsis cuam tshuam. Tsis tas li ntawd, los ntawm kev ua kom zoo ntawm kev tsim hluav taws xob thiab siv ntau- txheej txheej pawg thawj coj saib, thermal kev ntxhov siab tuaj yeem cuam tshuam zoo dua thiab qhov cuam tshuam ntawm thermal expansion ntawm pcb kev ua tau zoo tuaj yeem txo.
Nyob rau hauv cov nqe lus ntawm kev kho deg, tsim nyog txheej txheem xws li electroless npib tsib xee plating thiab organic solderability tiv thaiv zaj duab xis tau tsim raws li cov yam ntxwv ntawm PTFE cov ntaub ntawv. Cov txheej txheem no tsis tsuas yog tiv thaiv tooj liab circuits los ntawm oxidation thiab corrosion, tab sis kuj txhim kho cov solderability ntawm cov ntawv luam Circuit Court boards, kom ntseeg tau tias txhim khu kev qha soldering ntawm cov khoom siv hluav taws xob.
Daim ntawv thov dav ntawm PTFE siab - cov khoom siv zaus pcb
