6.Tsis paub tias muaj pes tsawg zaus PCB
Cov khoom siv hluav taws xob uas muaj lub siab ntev yog cov niaj hnub pib xyaum, tshwj xeeb tshaj yog nyob hauv wireless network. Kev sib txuas lus los ntawm kev sib txuas lus sai sai, cov ntaub ntawv tawm mus rau kev kub ceev thiab siab. Yog li tsim cov khoom tshiab yuav tsum tau siv cov thawv ntim khoom, lub zog hauv xov tooj, lub xov tooj ntawm lub chaw nres tsheb txais cov chaw nres tsheb thiab lwm yam, cov khoom siv sib txuas lus yuav tsum siv cov PCB siab.
Cov yam ntxwv ntawm PCB ua raws li txuas mus ntxiv no:
1) DK yuav tsum yog me thiab ruaj khov txaus, feem ntau me dua qhov zoo, DK siab yuav ua rau cov teeb meem kis qeeb.
2) DF yuav tsum yog me me, uas feem ntau tshwm sim rau kev sib kis ntawm cov teeb liab, DF me dua yuav ua rau cov teeb meem me me qis.
3) Lub thermal expansivity yuav tsum yog tib yam nrog tooj ci ntawv nyiaj ntau li ntau tau, vim tias qhov txawv yuav ua rau cov ntawv ci sib cais sib cais hauv cov kev hloov ntawm txias thiab cua sov.
4) Kev nqhis dej yuav tsum tsis tshua muaj, dej tsis txaus siab yuav cuam tshuam rau DK thiab DF thaum nyob hauv chaw ntub dej.
5) Cov cua kub uas tiv thaiv cov khoom, chemistry resisting, impact endurance, tev tawv los tiv thaiv yuav tsum zoo.
Feem ntau hais lus, muaj cov zauv los txhais tau tias yog li ntawm 1 GHz. Tam sim no, polyfluoretraethylene (PTFE) khoom siv dav siv PCB manufacturing, nws tseem hu ua Teflon, uas zaus feem ntau saum toj 5GHz. Ntxiv mus, FR4 los yog PPO substrate yuav siv rau cov khoom zaus ntawm 1 GHz ~ 10 GHz. No peb siab muaj zog substrate muaj hauv qab sib txawv:
Kev xav txog laminate tus nqi ntawm FR4, PPO thiab Teflon, FR4 yog qhov pheej yig tshaj, thaum Teflon yog tus tseem kim tshaj plaws. Nyob rau hauv cov nqe lus ntawm DK, DF, dej absorption thiab zaus feature, Teflon yog qhov zoo tshaj plaws. Thaum twg daim ntawv thov yuav tsum tau muaj zog tshaj 10GHz, tsuas yog peb tuaj yeem xaiv Teflon PCB substrate los ua. Obviously, qhov kev ua tau zoo ntawm Teflon yog zoo dua li lwm cov substrate, Txawm li cas los, Teflon substrate muaj cov disadvantage ntawm tus nqi siab thiab cov hluav taws kub loj resisting. Txhawm kom txhim kho PTFE txoj kev sib zog thiab qhov kub ua kom tsis muaj zog, muaj coob tus SiO2 lossis fiber ntau iav ua cov ntawv sau. Rau lwm cov tes, vim molecule inertia ntawm PTFE cov ntaub ntawv, uas nws tsis yog yooj yim los ua ke nrog tooj ci ntawv ci, yog li, nws yuav tsum tau ua tshwj xeeb saum npoo kho sab ua ke. Kev xav txog kev sib tov ua ke, feem ntau siv tshuaj lom neeg ua rau PTFE ntws los yog cov ntshav dej mus rau ntxiv rau qhov chaw npau taws los yog ntxiv ib zaj duab xis ntawm PTFE thiab tooj ci cov ntawv nyiaj, tab sis cov no muaj feem xyuam rau kev ua haujlwm ntawm kev ua haujlwm.
Uniwell circuits muaj ntau ntau PCB xws li Rogers, Taconic, Arlon thiab lwm yam, rau ntau hom highstrates, peb muaj txaus cia kom ceev ceev tus me nyuam.
