Lub rooj tsav xwm ob tog yog ib qho tseem ceeb ntawm cov smartphones, khoos phis tawj, tsheb, cov cuab yeej siv dav hlau uas peb siv hauv peb lub neej txhua hnub.
Kauj Ruam 1: Kev npaj cov khoom siv raw
Ib tug ob-sided multi-layer Circuit Court board yog tsim los ntawm ntau yam nyias nyias thiab ruaj khov txheejFR4cov ntaub ntawv, yog li ntawd, nws yog ib qho tsim nyog los npaj cov khoom siv FR4 txaus ua ntej. Cov khoom siv FR4 muaj cov khoom siv hluav taws xob zoo thiab cov khoom siv dag zog, thiab feem ntau yog siv los tsim cov khoom siv hluav taws xob. Tsis tas li ntawd, cov ntaub ntawv xws li tooj liab ntawv ci, cov kuab tshuaj organic, thiab cov nplaum nplaum uas tiv taus kub kub yuav tsum tau npaj.
Kauj ruam 2: Circuit Court Design
Ua ntej pib tsim ob-sided multi-layer Circuit Court boards, yuav tsum tsim Circuit Court. Raws li qhov yuav tsum tau ua ntawm cov khoom, cov neeg tsim qauv yuav siv cov software tsim hluav taws xob los kos cov duab kos duab, txiav txim siab cov kev taw qhia thiab kev sib txuas ntawm lub voj voog. Qhov tseem ceeb ntawm cov kauj ruam no yog qhov tseeb ntawm tus kheej, raws li txhua yam pib nrog kev tsim.
Kauj ruam 3: Graphic Printing
Cov kauj ruam tom ntej ntawm kev ua ib lub rooj tsav xwm Circuit Court yog graphic printing, feem ntau yog siv tshuab photolithography. Ua ntej, hloov cov qauv mus rau ib tug qhuav adhesive txheej, ces irradiate nws nrog ultraviolet lub teeb los kho cov photoresist txheej thiab muab nws nrog cov qauv. Tom ntej no, los ntawm acid etching, lub uncured nplaum txheej thiab tooj liab ntawv ci raug muab tshem tawm ua ke los tsim cov yam xav tau conductive qauv.
Kauj Ruam 4: Etching thiab Drilling
Tom qab ua tiav cov duab luam ntawv, etching thiab drilling yog xav tau. Nyob rau hauv cov kauj ruam no, siv ib tug etchant kom tshem tawm cov ntawv ci tooj liab uas tsis muaj kev tiv thaiv thiab khaws cov ntawv ci tooj liab uas xav tau rau lub voj voog. Tom qab ntawd siv lub tshuab drilling los laum qhov los txuas cov txheej txheem sib txawv ntawm lub rooj tsav xwm ob tog.
Kauj Ruam 5: Txheej txheej
Tom qab etching thiab drilling, multi-layer circuit board yuav tsum tau laminated. Tom qab txheej txheej ntawm Circuit Court board nrog high-temperature resistant nplaum, nias lawv ua ke los ua ib tug tag nrho. Los ntawm cua sov thiab siab, cov nplaum ntawm txhua txheej yog kho kom tsim tau ib lub rooj tsav xwm ob sab ntau txheej.
Kauj Ruam 6: Kev kuaj Circuit Court thiab kho
Tom qab ntau lawm, kev ntsuas hluav taws xob yuav tsum tau ua kom ntseeg tau tias kev ua haujlwm ib txwm muaj ntawm lub rooj tsav xwm ob tog. Yog hais tias muaj ib tug malfunction los yog defect, nws yuav tsum tau kho. Cov kauj ruam no yog qhov tseem ceeb rau kev ua kom cov khoom zoo thiab kev ntseeg siab.
Kauj Ruam 7: Txheej txheej kho thiab vuam
Tom qab ua tiav qhov kev ntsuam xyuas Circuit Court, nws yog ib qho tsim nyog yuav tau ua cov txheej txheem txheej txheej thiab soldering. Kho sab nrauv ntawm lub rooj tsavxwm Circuit Court nrog cov tshuaj tiv thaiv Circuit Court los ntawm oxidation thiab paug. Tom ntej no, cov khoom siv txuas nrog rau lub rooj tsav xwm hauv Circuit Court siv cov cuab yeej siv tshuab thiab txuas nrog lub voj voog.
Kauj Ruam 8: Txheej thiab Kho Ntog
Cov kauj ruam kawg yog txheej thiab kho qhov chaw. Nyob rau hauv cov kauj ruam no, ib tug tiv thaiv zaj duab xis yog siv rau saum npoo ntawm lub Circuit Court board siv cov txheej txheem tooj liab-clad los tiv thaiv cov circuits thiab cov khoom. Tsis tas li ntawd, kev kho saum npoo tuaj yeem ua tiav, xws li tshuaj tsuag tin, tshuaj txau kub, thiab lwm yam, txhawm rau ua kom cov conductivity thiab corrosion kuj ntawm lub circuit.
Summary : Kev tsim khoom ntawm ob-sided multi-layer circuit boards yog cov txheej txheem nruj thiab nyuaj uas yuav tsum tau siv thev naus laus zis txaus thiab kev paub dhau los. Tsuas yog cov kauj ruam saum toj no tsis tuaj yeem ua kom pom nws cov ntsiab lus, vim tias txhua kauj ruam muaj cov ntsiab lus ntxiv thiab cov txheej txheem los tshawb nrhiav.
