Raws li lub hauv paus tseem ceeb ntawm cov khoom siv hluav taws xob, kev tsim kho tshiab thiab kev kho dua tshiab ntawm cov txheej txheem tsim cov ntawv luam tawm Circuit Board yog qhov tseem ceeb. Raws li kev tshaj lij pcb manufacturing technology,dig muag faus qhov technologytab tom tau txais kev saib xyuas dav dav thiab kev thov hauv kev lag luam, muab kev txhawb nqa zoo rau kev ua haujlwm me me, siab - ntom, thiab siab - teeb liab kis tau tus mob ntawm cov khoom siv hluav taws xob.
1, Txhais thiab lub hauv paus ntsiab lus ntawm qhov muag tsis pom kev faus qhov tshuab
Qhov muag tsis pom qhov faus thev naus laus zis hais txog cov txheej txheem ntawm kev tsim cov qhov muag tsis pom kev thiab faus qhov ntawm pcb boards. Qhov qhov muag tsis pom kev yog ib hom uas tsis yog los ntawm lub qhov uas qhib ntawm ib qho kawg ntawm qhov chaw ntawm pcb thiab xaus ntawm ib txheej txheej hauv lub rooj tsavxwm, zoo li lub taub ntawm cov dej khov nab kuab, tsuas yog ib qho kawg nkaus xwb. Thiab cov qhov faus tau muab zais tag nrho hauv pcb, txuas cov txheej txheej txheej txheej sib txawv, uas tsis tuaj yeem pom ncaj qha los ntawm qhov chaw ntawm pcb. Cov txheej txheem no siv cov txheej txheem xws li laser drilling, mechanical drilling, thiab electroplating los tsim cov txheej txheem sib txuas tshwj xeeb hauv ntau- txheej pcb boards, ua rau kom qhov ceev ntawm kev xaim thiab qhov nyuaj ntawm kev sib txuas hluav taws xob.
Siv lub pcb pawg thawj coj saib ntawm lub xov tooj smartphone ua piv txwv, vim nws qhov chaw tsis tshua muaj kev txwv sab hauv, nws yuav tsum muaj kev sib koom ua ke ntawm ntau yam khoom siv xws li processors, nco, koob yees duab modules, thiab kev sib txuas lus modules, uas qhov chaw xav tau siab heev ntawm kev sib txuas ntawm pcb. Lub qhov muag dig qhov faus thev naus laus zis tuaj yeem ua tiav cov kev sib txuas yooj yim ntawm cov txheej txheem sib txawv hauv qhov chaw txwv los ntawm kev tsim cov qhov muag tsis pom kev thiab cov qhov faus, tsim cov xwm txheej rau siab - cov xov hlau ceev thiab ua tau raws li qhov xav tau ntawm cov xov tooj smartphones.
2, Qhov zoo ntawm qhov muag tsis pom faus qhov tshuab
(1) Ua kom cov kab hluav taws xob ceev
Cov tsoos los ntawm - qhov tsim, uas khiav los ntawm tag nrho cov pcb board, siv ntau qhov chaw thiab txwv qhov yooj yim ntawm kev xaim. Cov txheej txheem faus qhov muag tsis pom kev zoo txo cov hneev taw los ntawm qhov ntawm lub qhov pcb los ntawm kev zais cov ntsiab lus sib txuas hauv lub rooj tsavxwm, yog li muab ntau qhov chaw rau kev xaim. Piv txwv li, nyob rau hauv lub pcb tsim ntawm ib co high -kawg ntsiav tshuaj computers, kev siv cov dig muag faus qhov tshuab tau nce cov xov hlau ceev ntau zaus piv rau cov txheej txheem ib txwm, ua kom muaj kev sib koom ua ke ntawm ntau lub voj voog hauv qhov chaw tsawg thiab ua tau raws li qhov siab -kev ua tau zoo thiab kev xav tau ntau yam ntawm cov ntsiav tshuaj computers.
(2) Txhim kho teeb liab kev ncaj ncees
Lub teeb liab kev ncaj ncees yog qhov tseem ceeb hauv kev sib kis ntawm siab -cov teeb liab ceev ceev thiab siab - zaus analog teeb liab. Qhov muag tsis pom kev faus qhov tshuab tuaj yeem txo qhov ntev thiab nyuaj ntawm cov teeb liab kis tau tus mob, nrog rau cov teeb meem xws li teeb liab xav txog thiab crosstalk. Noj pcb pawg thawj coj ntawm 5G kev sib txuas lus hauv paus chaw nres tsheb ua piv txwv, lub teeb liab zaus tuaj yeem ncav cuag ntau GHz, thiab cov teeb liab kis tau tus mob ceev heev. Kev siv lub qhov muag tsis pom kev siv tshuab tuaj yeem txo qhov cuam tshuam thaum lub teeb liab kis tau tus mob, ua kom cov teeb liab sib kis tau ruaj khov, txhim kho kev ua haujlwm ntawm cov khoom siv sib txuas lus, thiab ua tau raws li qhov xav tau ntawm siab - cov ntaub ntawv xa mus ceev thiab siab - zaus teeb liab ua.
(3) Paub txog kev tsim qauv miniaturization
Nrog rau txoj kev loj hlob ntawm cov khoom siv hluav taws xob mus rau slimness, cov kev cai rau pcb loj thiab tuab yog ua nruj me ntsis. Cov txheej txheem faus qhov muag tsis pom kev ua rau pcb boards txo qhov loj thiab tuab thaum tuav lossis nce kev ua haujlwm. Piv txwv li, hauv cov khoom siv hnav xws li smartwatches, qhov chaw sab hauv yog qhov tsawg heev. pcb boards tsim siv lub qhov muag tsis pom kev faus qhov thev naus laus zis tuaj yeem ua tiav kev sib txuas hauv Circuit Court hauv qhov chaw tsawg, ua tau raws li qhov kev thov rau miniaturization tsim ntawm smartwatches, ua rau lawv sib zog, nqa tau yooj yim, thiab hnav zoo dua.
3, Kev tsim cov txheej txheem ntawm qhov muag tsis pom kev faus qhov tshuab
(1) Drilling txheej txheem
Laser drilling: Rau qhov me me dig muag qhov, laser drilling tshuab feem ntau yog siv. Laser tuaj yeem ua kom pom tseeb thiab ua kom muaj qhov kub thiab txias ntawm pcb board, ua rau lub rooj tsavxwm vaporize thiab tsim qhov. Txoj kev no tuaj yeem ua tiav qhov loj me me me, xws li 0.075mm lossis me dua, nrog cov phab ntsa du, qhov chaw me me rau cov cua sov, thiab kev puas tsuaj tsawg rau lub rooj tsavxwm. Thaum ua qhov me me qhov muag tsis pom hauv lub xov tooj smartphone pcb boards, laser drilling tshuab tuaj yeem ua tau raws li qhov siab - qhov yuav tsum tau ua, kom ntseeg tau qhov zoo thiab ua haujlwm ntawm qhov muag tsis pom.
Mechanical Drilling: Rau qee qhov qhov muag tsis pom loj thiab faus qhov, cov tshuab drilling feem ntau yog siv. Los ntawm kev siv siab - cov cuab yeej drilling precision los tswj qhov tsis xws li laum nrawm thiab pub tus nqi, qhov yuav tsum tau muaj tuaj yeem drilled ntawm lub rooj tsavxwm pcb. Thaum ua pcb boards rau cov khoom siv hauv aerospace, vim muaj kev ntseeg siab heev, cov neeg kho tshuab drilling tuaj yeem xyuas kom meej qhov tseeb thiab qhov perpendicularity ntawm lub qhov, ua tau raws li cov kev xav tau ntawm kev sib txuas hauv Circuit Court.
(2) Qhov kev kho metalization
Tom qab drilling, nws yog ib qho tsim nyog yuav tsum tau metalize qhov muag tsis pom thiab faus qhov kom lawv ua tau. Cov txheej txheem no feem ntau yog siv cov tshuab electroplating los raus pcb board hauv cov tshuaj electroplating uas muaj hlau ions, xws li tooj liab ions. Los ntawm electrolysis, cov hlau ions tau muab tso rau ntawm lub qhov phab ntsa los tsim ib txheej hlau tsis sib xws. Hauv kev tsim cov pcb boards rau automotive electronics, qhov zoo ntawm qhov metallization ncaj qha cuam tshuam rau kev ntseeg siab ntawm cov tshuab hluav taws xob. Los ntawm kev tswj nruj ntawm cov txheej txheem electroplating, lub thickness thiab adhesion ntawm cov hlau txheej hauv lub qhov tuaj yeem ua kom ntseeg tau, ua kom cov teeb liab ruaj khov.
(3) Txheej thiab tom qab ua tiav
Cov pcb boards uas tau dhau los ua qhov drilling thiab qhov metallization kev kho mob yuav tau laminated nrog cov ntaub ntawv xws li cov ntawv kho semi-kho. Nyob rau hauv qhov siab - kub thiab siab - ib puag ncig siab, cov ntawv kho ib nrab yog yaj thiab ua rau qhov sib txawv ntawm cov txheej txheem, nruj nreem khi lawv ua ke kom ua tiav ntau- txheej pcb board. Tom qab lamination, yuav tsum tau ua cov kauj ruam tom ntej, xws li circuit etching, solder mask printing, character printing, etc., kom ua tiav cov khoom ntawm pcb board. Hauv kev tsim cov txheej txheem ntawm lub khoos phis tawj motherboard, kev tswj kom zoo ntawm cov txheej txheem lamination yog qhov tseem ceeb. Kev tswj xyuas qhov tsis raug xws li qhov kub thiab txias, siab, thiab lub sijhawm tuaj yeem ua kom qhov kev sib raug zoo ntawm cov khaubncaws sab nraud povtseg, tsis txhob muaj qhov tsis xws luag xws li delamination thiab npuas, thiab xyuas kom meej qhov kev ua tau zoo thiab kev ntseeg siab ntawm lub motherboard.
