Raws li "nerve center" ntawm cov cuab yeej siv,industrial tswj circuit boardsnqa cov haujlwm tseem ceeb xws li teeb liab kis tau tus mob thiab kev qhia ua haujlwm. Lawv qhov kev ua tau zoo ncaj qha txiav txim siab kev ua haujlwm ntawm kev ua haujlwm thiab kev ntseeg siab ntawm cov cuab yeej siv khoom lag luam. Los ntawm kev tswj hwm ntawm cov kab ntau lawm kom ruaj khov ntawm cov phiaj xwm ntse, kev tswj hwm kev lag luam hauv Circuit Court boards ua lub luag haujlwm tseem ceeb.
Kev tshuaj xyuas tag nrho cov txheej txheem ntawm kev lag luam tswj kev lag luam Circuit Court board ua
(1) Ua tib zoo xaiv cov khoom siv raw
Qhov zoo ntawm raw cov ntaub ntawv yog lub hauv paus ntawm kev ua tau zoo ntawm Circuit Court boards. Lub substrate yuav tsum xav txog hluav taws xob, mechanical, thiab tshav kub tsis kam ua kom tiav. FR-4 los yog ceramic substrates nrog cov iav hloov pauv kub yog feem ntau siv nyob rau hauv qhov kub thiab txias. Tus qub muaj tus nqi siab ua haujlwm nrog Tg ntawm 130℃140 degree, thaum tom kawg, xws li alumina ceramic substrates, muaj thermal conductivity ntawm 20-30W / (m · K) thiab melting point txog 2050 degree. Lub thickness ntawm high-purity electrolytic tooj liab ntawv ci, raws li ib tug tseem ceeb conductive, nyob ntawm seb qhov yuav tsum tau nqa tam sim no. Nyob rau tib lub sijhawm, txhua tus resistor, capacitor, nti thiab lwm yam khoom siv yuav tsum tau soj ntsuam nruj thiab kuaj kom paub meej qhov tsis raug.
(2) Sab hauv Circuit Court yog ua tib zoo crafted
Kev tsim khoom ntawm sab hauv Circuit Court yog kev ua haujlwm zoo. Ua ntej, tshem tawm cov nplaum, roj, thiab txhuam cov PCB substrate los xyuas kom meej qhov du thiab huv si. Tom qab siv cov zaj duab xis qhuav, cov qauv Circuit Court raug xa mus siv lub tshuab raug. Tom qab kis tau, cov yeeb yaj kiab qhuav dhau yog tsim los tshem tawm, thiab tom qab ntawd cov ntawv ci tooj liab uas tsis muaj kev tiv thaiv yog etched kom pom cov txheej txheej hauv Circuit Court. Thaum kawg, cov yeeb yaj kiab raug tshem tawm kom tiav cov khoom tsim tawm. Cov kev txwv ntawm txhua kauj ruam yog tswj nruj me ntsis kom ntseeg tau qhov tseeb ntawm lub voj voog.
(3) Seamless txuas ntawm cov txheej txheem compression
Cov txheej txheem lamination yog tus yuam sij rau kev sib koom ua ke ntawm txheej txheej txheej txheej nrog txheej txheej tooj liab. Ua ntej ua haujlwm, ua tib zoo kho cov txheej txheem sab hauv thiab sab nrauv tooj liab kom tshem tawm cov impurities thiab roj stains. Tom qab stacking cov ntaub ntawv rwb thaiv tsev ua ntu zus, lawv raug xa mus rau cov khoom siv laminating. Siv plaub txheej pawg thawj coj ua piv txwv, qhov ntsuas kub yog tswj ntawm 180℃-220 degree, lub siab yog 3-5MPa, thiab nws kav ntev li 2-3 teev los xyuas kom meej tias txhua txheej yog nruj me ntsis sib txuas thiab tsim cov hluav taws xob ruaj khov.
(4) Qhov tseeb qhov chaw ntawm cov txheej txheem drilling
Drilling qhov qhib channel rau tivthaiv pins thiab vias yuav tsum muaj siab precision. Rau siab - qhov sib txawv ntawm qhov sib txuas ntawm lub rooj tsavxwm, lub micro qhov taub tuaj yeem tsawg dua 0.1mm, thiab txoj haujlwm raug yuam kev yog tswj tsis pub dhau ± 0.05mm. Cov cuab yeej ua haujlwm siab tshaj plaws nyob ntawm siab - CNC tshuab thiab cov cuab yeej xyaum ua haujlwm kom ua tiav qhov kev ua haujlwm zoo los ntawm kev ua haujlwm zoo, ua kom muaj kev sib txuas thiab hluav taws xob txuas ntxiv.
(5) Lub voj voog sab nrauv yog ua haujlwm zoo
Kev tsim tawm ntawm cov txheej txheem sab nraud zoo ib yam li cov txheej txheej sab hauv, tab sis yuav tsum tau ua kom raug ntau dua vim muaj kev koom tes ntawm cov ntaub qhwv thiab tus pin qhov. Ua los ntawm cov txheej txheem xws li ua ntej- kho, qhuav zaj duab xis bonding, raug, kev loj hlob, etching, thiab tshem tawm zaj duab xis. Kev tsim cov ntaub qhwv ntsej muag nruj me ntsis tswj qhov loj, zoo, thiab flatness. Rau tus pin chips nrog lub suab zoo hauv qab 0.5mm, qhov tseeb ntawm qhov loj ntawm qhov sib tw ncav cuag ± 0.02mm, thiab qhov kev ua yuam kev flatness tsis tshaj 0.01mm.
(6) Solder mask thiab text printing coloring
Solder mask ntsuab roj yog txheej tiv thaiv ntawm lub rooj tsav xwm Circuit Court. Ua ntej luam ntawv, lub rooj tsav xwm Circuit Court yuav tsum tau ntxuav kom huv si kom tshem tawm cov impurities. Siv cov roj ntsuab sib npaug los ntawm kev tshuaj ntsuam luam ntawv lossis tshuaj tsuag thiab kho kom tsim tau cov txheej txheem tiv thaiv zoo. Tib lub sijhawm sau cov ntawv sau meej, xws li cov lej feem, kom yooj yim installation, debugging, thiab tu, thiab xav tau cov ntawv ntshiab, raug, thiab ruaj ntseg.
(7) Kev ntsuas nruj kom ntseeg tau qhov zoo
Kev ntsuam xyuas thiab kev soj ntsuam zoo yog qhov tseem ceeb rau kev ruaj ntseg zoo. Flying needle testing pom hluav taws xob ua tau zoo, ua raws li kev tshuaj xyuas qhov muag kom ua ntej tshuaj ntsuam xyuas qhov tsis xws luag. Tsis siv neeg kho qhov muag tshuaj ntsuam xyuas (AOI) scans vuam thiab Circuit Court teeb meem nrog siab precision, thiab ua hauj lwm simulates tiag tiag scenarios. Tsuas yog lub rooj tsav xwm hauv Circuit Court uas tau dhau txheej txheej los ntawm kev sim txheej tuaj yeem mus rau theem tom ntej.
(8) Kev nyab xeeb ntawm kev ntim khoom tiav
Cov khoom siv hluav taws xob tsim nyog tau ntim rau hauv lub tshuab nqus tsev lossis cov dej noo- cov ntaub ntawv pov thawj kom tsis txhob ya raws, hluav taws xob zoo li qub, thiab kev puas tsuaj rau txhua yam thaum thauj thiab khaws cia. Lub ntim sab nrauv yog sau nrog cov ntaub ntawv tseem ceeb xws li cov npe khoom, cov lus qhia tshwj xeeb, thiab cov qauv kom yooj yim traceability thiab kev tswj xyuas, thiab thaum kawg xa khoom zoo raws li cov neeg siv khoom xav tau.
