Iav PCB yog hom tshiab ntawm cov khoom siv hluav taws xob cov khoom siv ua los ntawm kev sib xyaw ntawm cov iav fiber ntau thiab epoxy cob. Cov hauv qab no yog cov ncauj lus kom ntxaws txog iav pcb:
Cov Khoom Siv Cov Khoom Siv
Iav PCB feem ntau yog tsim ntawm cov khob fiber ntau thiab epoxy cob, thiab kev sib xyaw ua ke khob pcb nrog cov yam ntxwv siab thiab kub tsis kam.
Qhov Zoo
Lub zog siab: qhov sib ntxiv ntawm cov iav fibers muab cov iav PCbs zoo nkauj heev thiab muaj peev xwm withstand siab kev ntxhov siab ntau thiab siab.
Cov kev kub siab kuj suav: piv nrog cov tsoos fr4 cov ntaub ntawv, iav pcbs muaj ua haujlwm zoo dua li 150 qhov teeb meem tau yooj yim xws li Circuit Court tsoo thiab muag muag.
Nplaim retardancy: iav pcbs muaj nplaim taws zoo retardancy thiab tuaj yeem tiv thaiv tus kab mob hluav taws rau qee yam.
Chaw thov
Vim nws cov kev ua tau zoo, iav pcbs tau siv dav hauv cov khoom siv hluav taws xob siab xws li cov cuab yeej tsheb hluav taws xob, cov cuab yeej tsheb ciav hlau, thiab lwm yam.
Cov yam ntxwv ib puag ncig
Iav iav pcb tsis muaj cov tshuaj phem xws li cov hmoov txhuas thiab muaj kuab lom, thiab lwm yam kuab paug tsis muaj kev tiv thaiv thiab kev tiv thaiv ib puag ncig.
Kev Xav Tau Lag Luam
Txawm hais tias iav pcbs muaj ntau yam zoo, vim lawv tus nqi siab, kev thov kev lag luam me me. Txawm li cas los xij, nrog kev nce qib nruam ntawm kev siv tshuab thiab kev nthuav dav ntawm cov khoom lag luam hauv hluav taws xob siab, cov ntawv thov kev ua lag luam thiab cov liaj ua lag luam ntawm iav pcbs yuav txuas ntxiv mus ntxiv.
2, iav Epoxy PCB (Epoxy iav ntaub tooj liab cov ntaub ua los ntawm alkali fiber ntau cov ntaub so (lossis npog nrog electrolytic tooj liab ntawv ci ntawm ib lossis ob sab, thiab ces kub nias.
Cov Khoom Siv Cov Khoom Siv
Muaj cai ntawm Alkali Dawb iav Faj fiber ntau ntaub (kev siv lub zog), nws muaj cov yam cuab yeej ntawm cov khoom siv muaj zog thiab cov khoom siv Dielectric heev.
Yam ntxwv tseem ceeb
Thaum tshav kub kub nce qib: nce mus rau F Theem (155 degree), nrog noo noo noo resistance.
Kev ua hluav taws xob: Kev ntsuas hluav taws xob siab ntawm cov hluav taws xob kub thiab ruaj khov rau hluav taws xob hauv qhov chaw siab huab cua.
Daim Ntawv Thov Kev Ua Yeeb Yam: Haum rau kev tsim cov ntawv luam tawm Circuit Coffic laug cam (PCBs), nws ua lub luag haujlwm hauv kev tiv thaiv kev txhawb nqa hluav taws xob thiab muab cov dej noo kev tiv thaiv.
Qhov sib txawv los ntawm ib txwm muajF4txiag ntoo
Iav Epoxy PCB belongs rau ib hom f4 substrate, tab sis hais txog cov ntawv sib khi nrog cov xwm txheej uas muaj zog rau cov khoom cua kub thiab cov khoom siv dielectric.
