Circuit Board samplingyog ib kauj ruam tseem ceeb hauv kev hloov cov khoom los ntawm kev tsim cov duab kos mus rau kev tsim khoom tiag. Cov lus hais rau Circuit Board sampling, raws li qhov pib ntawm cov txheej txheem sampling, tsis tsuas yog cuam tshuam rau kev tswj tus nqi ntawm lub tuam txhab, tab sis kuj cuam tshuam rau kev ua haujlwm ntawm qhov project. Cov lus hais raug thiab tsim nyog tuaj yeem tsis tsuas yog ua kom cov nyiaj tau los ntawm cov neeg xa khoom, tab sis kuj muab cov neeg siv khoom nrog tus nqi - cov kev pabcuam zoo.
1, Cov ntsiab lus tseem ceeb cuam tshuam rau cov lus hais rau Circuit Board sampling
(1) Circuit Board Parameters
Layer suav: Tus naj npawb ntawm cov khaubncaws sab nraud povtseg ntawm lub rooj tsavxwm Circuit Court yog ib qho tseem ceeb cuam tshuam rau cov lus hais. Cov txheej txheem ntau dua, cov txheej txheem ntau lawm yog qhov nyuaj, thiab ntau cov ntaub ntawv thiab cov txheej txheem yuav tsum tau ua. Piv txwv li, piv rau ib lub vaj huam sib luag, ob npaug -ib sab vaj huam sib luag yuav tsum tau xaim, drilling, electroplating, thiab lwm yam kev ua haujlwm ntawm ob sab ntawm lub substrate, uas ua rau muaj kev nyuaj siab ntau thiab nqi; Multilayer boards xav tau cov txheej txheem nyuaj xws li txheej txheej duab tsim, lamination, thiab qhov muag tsis pom kev, thiab cov lus hais yuav nce qib ntawm cov txheej txheem ntxiv.
Loj: Qhov loj ntawm lub rooj tsav xwm Circuit Court ncaj qha cuam tshuam rau tus nqi ntawm cov khoom siv raw. Lub rooj tsav xwm loj dua yuav tsum muaj cov ntaub ntawv ntau dua, cov ntawv ci tooj liab, lub npog ntsej muag lub ntsej muag, thiab lwm yam, thiab tseem siv cov cuab yeej siv ntev dua thiab cov neeg ua haujlwm hauv cov txheej txheem tsim khoom, ua rau cov nqi nce thiab cov lus hais ntau dua.
Kab dav / qhov sib txawv: Cov kab dav dav thiab qhov sib txawv yuav tsum muaj cov txheej txheem ntau lawm. Txhawm rau kom ua tiav cov kab dav me me thiab qhov sib txawv, cov cuab yeej siv tau zoo dua, cov txheej txheem etching ntau dua, thiab kev tswj hwm nruj dua yuav tsum tau ua, uas yuav tsum tau ua kom muaj txiaj ntsig ntau ntxiv thiab cuam tshuam rau hauv cov lus hais. Piv txwv li, nyob rau hauv siab - qhov ceev interconnect circuit boards, kab dav / qhov sib txawv yuav ncav cuag kaum tawm micrometers lossis txawm me dua, thiab tus nqi piv txwv yuav siab dua li ntawm cov kab hluav taws xob zoo tib yam.
Aperture: Kev ua vaj huam sib luag nrog cov apertures me yog qhov nyuaj, tshwj xeeb tshaj yog rau qhov me me xws li micropores. Kev tsim cov apertures me dua 0.3 hli yuav tsum tau siv cov khoom siv laser drilling, thiab cov kev cai nruj tau muab tso rau ntawm qhov tseeb drilling thiab qhov zoo ntawm phab ntsa. Tsis tas li ntawd, aperture me me kuj tseem tuaj yeem koom nrog cov txheej txheem tshwj xeeb electroplating los xyuas kom meej qhov sib xws thiab kev ntseeg tau ntawm cov txheej tooj liab hauv lub qhov, uas yuav ua rau cov nqi nce ntxiv thiab cuam tshuam rau cov lus hais.
(2) Kev xaiv cov khoom siv
Cov khoom siv substrate: Cov khoom sib txawv ntawm cov khoom siv substrate muaj cov nqi sib txawv. Hom FR-4 epoxy resin iav fiber board muaj tus nqi qis thiab yog cov khoom siv siv ntau tshaj plaws; High zaus boards muaj cov yam ntxwv ntawm tsis tshua muaj dielectric tsis tu ncua thiab poob qis, ua rau lawv haum rau high-frequency teeb liab kis tau tus mob, tab sis lawv yog kim; Hlau raws li Circuit Court boards muaj kev ua tau zoo thaum tshav kub kub dissipation thiab feem ntau yog siv rau hauv cov khoom siv hluav taws xob hluav taws xob. Lawv cov nqi kuj siab dua li cov khoom siv substrate. Xaiv cov khoom sib txawv ntawm cov substrate tuaj yeem ua rau muaj kev hloov pauv loj hauv cov qauv quotes.
Copper foil thickness: Lub thickness ntawm cov ntawv ci tooj liab cuam tshuam rau cov conductivity thiab tam sim no nqa peev xwm ntawm lub rooj tsav xwm Circuit Court. Thicker tooj liab foils, xws li 35 μ m thiab 70 μ m, xav tau cov khoom siv tooj liab ntau dua thaum lub sij hawm tsim khoom thiab ua rau muaj kev nyuaj siab hauv etching thiab lwm yam txheej txheem, ua rau cov nqi ntau dua thiab cov lus hais ntau dua.
(3) Cov txheej txheem yuav tsum tau ua
Cov txheej txheem kev kho deg: Cov txheej txheem kev kho deg feem ntau suav nrog tin spraying, tshuaj kub deposition, tin deposition, nyiaj deposition, thiab lwm yam. Tus nqi ntawm tin spraying txheej txheem kuj tsis tshua muaj, tab sis lub nto flatness thiab solderability kuj tsis zoo; Cov txheej txheem chemical immersion kub tuaj yeem muab kev ua kom zoo, weldability, thiab oxidation tsis kam, haum rau siab - vuam precision thiab kub ntiv tes, tab sis tus nqi kuj yog siab; Lub immersion tin thiab immersion nyiaj txheej txheem muaj kev vuam zoo, tab sis lawv cov nqi kuj siab dua cov txheej txheem tshuaj tsuag tin. Kev xaiv txheej txheem kev kho deg sib txawv yuav cuam tshuam ncaj qha rau cov qauv hais.
Cov txheej txheem tshwj xeeb: Yog hais tias lub rooj tsav xwm Circuit Court yuav tsum tau ua tshwj xeeb xws li qhov muag tsis pom kev faus qhov, rov qab drilling, disk qhov, impedance tswj, thiab lwm yam, nws yuav ua rau kom ntau lawm nyuaj thiab nqi. Cov txheej txheem faus qhov muag tsis pom kev yuav tsum muaj kev tswj xyuas meej ntawm cov txheej txheej sab hauv drilling thiab lamination thaum lub sij hawm ntau - txheej txheem tsim khoom; Backdrilling thev naus laus zis yog siv los tshem tawm cov khoom seem seem thiab txhim kho cov teeb liab kev ncaj ncees; Lub disk drilling txheej txheem yuav tsum tau drilling nyob rau hauv nruab nrab ntawm lub solder ncoo, uas tsis tshua muaj siab precision yuav tsum tau; Kev tswj hwm impedance yuav tsum tau tswj xyuas nruj ntawm cov kab tsis sib txuas thiab cov yam ntxwv ntawm cov khoom siv hluav taws xob kom ua tau raws li cov kev xav tau ntawm cov teeb liab. Daim ntawv thov ntawm cov txheej txheem tshwj xeeb no yuav ua rau kom muaj txiaj ntsig zoo rau cov qauv hais.
(4) Kev txiav txim kom muaj nuj nqis thiab lub sijhawm xa khoom
Order kom muaj nuj nqis: Feem ntau, ntau cov qauv muaj, tus nqi qis dua. Qhov no yog vim hais tias nyob rau hauv cov txheej txheem ntau lawm, qee cov nqi xws li cov nqi engineering, cov nqi ua phaj, thiab lwm yam. Raws li qhov ntau ntxiv, cov nqi ruaj khov no tuaj yeem sib koom nrog ntau lub rooj sib tham hauv Circuit Court, yog li txo tus nqi ntawm ib lub rooj tsavxwm thiab ua rau cov lus hais tau zoo dua.
Lub sij hawm xa tuaj: Kev txiav txim ceev ceev xav kom cov neeg muag khoom kho lawv cov phiaj xwm tsim khoom, ua ntej tsim khoom, thiab tej zaum yuav xav tau cov neeg ua haujlwm ntxiv, cov cuab yeej siv nyiaj txiag, lossis txawm tias nrawm dua tab sis cov kev thauj mus los kim dua, ua rau cov nqi nrawm dua thiab cov nqe lus siab dua.
