Raws li cov cab kuj tseem ceeb rau kev sib txuas hluav taws xob ntawm cov khoom siv hluav taws xob, kev ntseeg siab ntawm pcb ncaj qha txiav txim siab txog kev ruaj ntseg thiab kev pab cuam lub neej ntawm tag nrho cov tshuab hluav taws xob. Los ntawm cov cuab yeej siv dav hlau mus rau cov khoom siv hluav taws xob niaj hnub, kev ntseeg siab ntawm pcb yog tus yuam sij rau kev ua haujlwm ntawm cov khoom siv. Yuav kom ua tiav kev ntseeg siab ntawm pcb, nws yog ib qho tsim nyog yuav tsum tswj hwm ntau yam xws li xaiv cov khoom siv, kev tsim kho kom zoo, kev tsim cov txheej txheem tswj, thiab kev tshuaj xyuas zoo.
1, Cov ntaub ntawv zoo nteg lub hauv paus txhim khu kev qha
Cov ntaub ntawv raw ntawm pcb muaj kev txiav txim siab rau nws txoj kev ntseeg siab. Raws li cov khoom tseem ceeb ntawm pcb, kev ua haujlwm ntawm tooj liab- clad laminate yog qhov tseem ceeb. Xaiv cov tooj liab- clad laminates nrog cov iav hloov pauv kub tuaj yeem txhim kho cov cua sov ntawm lub rooj tsav xwm luam tawm, ua kom lawv muaj lub cev ruaj khov thiab hluav taws xob zoo txawm tias nyob rau hauv qhov kub thiab txias, tsis txhob muaj teeb meem xws li substrate deformation thiab delamination los ntawm qhov kub thiab txias. Piv txwv li, hauv thaj chaw uas muaj kev ntseeg siab siab xws li tsheb hluav taws xob thiab kev tswj hwm kev lag luam, tooj liab -clad laminates nrog Tg qhov tseem ceeb tshaj 170℃feem ntau yog siv. Tib lub sijhawm, qhov dielectric tas li thiab dielectric poob tangent ntawm tooj liab-clad laminates kuj yuav tsum tau tswj nruj me ntsis. Cov ntaub ntawv uas tsis tshua muaj dielectric tsis tu ncua thiab tsis tshua muaj dielectric poob tuaj yeem txo qhov poob thiab qeeb thaum lub sij hawm xaim hluav taws xob, xyuas kom meej lub teeb liab, thiab ua tau raws li cov kev xav tau ntawm high{10}}ceev circuits.
Ntxiv nrog rau tooj liab- clad laminates, qhov zoo ntawm cov ntawv ci tooj liab tsis tuaj yeem tsis quav ntsej. Cov ntawv zoo tooj liab muaj qhov zoo ductility thiab conductivity, uas tuaj yeem txo cov kab tsis kam thiab teeb liab attenuation. Electrolytic tooj liab ntawv ci thiab dov tooj liab ntawv ci txhua tus muaj qhov zoo hauv kev ua tau zoo, thiab yuav tsum tau xaiv kom tsim nyog raws li cov ntawv thov tshwj xeeb ntawm pcb. Tsis tas li ntawd, cov nplaim retardant kev ua tau zoo ntawm cov ntaub ntawv substrate kuj yog ib qho tseem ceeb qhia rau kev ntsuas lawv kev ntseeg tau. Cov khoom siv hluav taws xob hluav taws xob uas ua tau raws li cov qauv thoob ntiaj teb tuaj yeem tiv thaiv kev sib kis ntawm hluav taws thaum muaj xwm txheej, ua kom muaj kev nyab xeeb ntawm cov khoom siv thiab cov neeg ua haujlwm.
2, Scientific tsim optimizes kev ntseeg tau
Tsim nyog pcb tsim yog ib qho tseem ceeb ua ntej kom ntseeg tau nws txoj kev ntseeg siab. Nyob rau hauv lub layout npaj theem, lub tshav kub dissipation yuav tsum tau ntawm cov Cheebtsam, electromagnetic compatibility yuav tsum tau, thiab cov teeb liab kis tau tus mob txoj kev yuav tsum tau txiav txim siab tag nrho. Disperse lub Cheebtsam nrog high kub tiam thiab cia kom txaus tshav kub dissipation qhov chaw, xws li tsim tshav kub dissipation vias, tshav kub dissipation tooj liab foils, thiab lwm yam., los pab txo lub zos kub thiab tiv thaiv pcb puas vim overheating. Rau siab - cov kab teeb liab ceev, kev tswj xyuas nruj ntawm cov kab ntev, cov yam ntxwv impedance, thiab cov teeb liab teeb tsa yog tsim nyog los txo cov teeb liab kev xav, crosstalk, thiab ncua, kom ntseeg tau tias muaj tseeb thiab ruaj khov teeb liab kis tau tus mob.
Kev npaj tsim nyog ntawm kev teeb tsa lub zog thiab cov kab hauv av yog qhov tseem ceeb hauv kev tsim cov kab hluav taws xob. Thaum siv ntau- txheej txheej pawg thawj coj tsim, cais cov txheej txheem hluav taws xob los ntawm cov txheej hauv av thiab ua tiav kev sib txuas zoo ntawm lub zog thiab hauv av los ntawm ntau tus vias tuaj yeem txo cov suab nrov ntawm lub zog thiab kev cuam tshuam ntawm electromagnetic. Nyob rau tib lub sijhawm, tsis txhob xaim los tsim cov voj voog thiab txo qhov muaj peev xwm ntawm hluav taws xob hluav taws xob thiab kev txais tos cuam tshuam. Tsis tas li ntawd, tsim nyog ua kom lub zog ntawm lub zog tsim ntawm pcb, xws li ntxiv ciam teb, txhawb cov tav, thiab lwm yam, tuaj yeem txhim kho lub pcb lub peev xwm los tiv thaiv kev cuam tshuam sab nraud thiab kev co, thiab tiv thaiv kev tawg thiab deformation thaum thauj thiab siv.
3, nruj craftsmanship xyuas kom raug zoo
Cov txheej txheem tsim khoom ntawm pcb ncaj qha cuam tshuam rau nws qhov kev ntseeg siab kawg. Nyob rau hauv cov txheej txheem drilling, kev tswj xyuas meej ntawm txoj haujlwm, txoj kab uas hla, thiab qhov tob ntawm lub borehole ua kom cov phab ntsa du thiab burr dawb, uas tuaj yeem zam qhov tsis zoo xws li kev sib txuas tsis zoo thiab luv luv ntawm cov hlau qhov uas tshwm sim los ntawm cov teeb meem zoo drilling. Electroplating txheej txheem yog qhov txuas tseem ceeb los xyuas kom meej qhov kev ntseeg tau ntawm pcb hluav taws xob sib txuas. By controlling the composition, temperature, current density and other parameters of the plating solution, the metal layer is uniformly and densely deposited on the hole walls and circuit surfaces, improving the conductivity and mechanical strength of the metalized holes.
Lub precision ntawm etching txheej txheem yog qhov tseem ceeb sib npaug. Tsim nyog etching parameter teeb tsa thiab kev tswj cov txheej txheem tuaj yeem ua kom qhov tseeb qhov tseeb thiab ntug zoo ntawm cov duab hluav taws xob, tsis txhob etching lossis tsis txaus etching ntawm circuits, thiab tiv thaiv luv luv lossis qhib circuits. Nyob rau hauv cov txheej txheem ntawm daim npog ntsej muag, xaiv qhov siab -kev ua tau zoo ntawm lub npog ntsej muag lub ntsej muag kom ntseeg tau tias tus number case sib npaug ntawm qhov chaw ntawm pcb, uas tuaj yeem tiv thaiv Circuit Court los ntawm kev yaig ib puag ncig thiab tsis txhob muaj teeb meem xws li kev sib txuas thiab kev sib txuas virtual thaum lub sij hawm soldering. Nyob rau tib lub sijhawm, cov txheej txheem kev kho deg nruj xws li tshuaj immersion thiab cua kub leveling tuaj yeem txhim kho cov solderability thiab oxidation tsis kam ntawm pcb nto, txuas lub neej kev pab cuam ntawm cov ntawv luam tawm Circuit Board.
4, Kev ntsuam xyuas ua kom ntseeg tau raws li cov qauv
Kev tshuaj xyuas zoo yog kab kawg ntawm kev tiv thaiv kom ntseeg tau qhov kev ntseeg siab ntawm cov ntawv luam tawm Circuit Board. Hauv kev tsim cov txheej txheem pcb, ntau cov txheej txheem tshuaj xyuas yuav tsum tau ua. Kev tshuaj xyuas qhov muag pom tau sai thiab raug txheeb xyuas qhov teeb meem hauv cov duab kos, xws li luv luv Circuit Court, qhib circuits, txawv kab dav, thiab lwm yam; X-Ray tshuaj ntsuam xyuas tuaj yeem nkag mus rau lub rooj tsav xwm luam tawm, kuaj xyuas qhov sib xyaw ua ke hauv cov txheej txheem, kev sib xyaw ua ke ntawm ntau- txheej boards, thiab xyuas kom muaj kev ntseeg siab ntawm cov qauv sab hauv; Slice tsom xam nrog rau lub cev slicing lub pcb thiab soj ntsuam nws cov qauv nyob rau hauv ib lub tshuab ntsuas los ntsuas qhov zoo ntawm cov txheej txheem xws li drilling, electroplating, thiab lamination.
Tsis tas li ntawd, kev ntsuam xyuas ib puag ncig kev ntseeg siab kuj yog ib qho tseem ceeb ntawm cov kauj ruam. Ntsuas qhov kev ua tau zoo ntawm pcb nyob rau hauv ib puag ncig sib txawv los ntawm kev simulation ib puag ncig xws li kub, tsis kub, cua sov, ntsev tsuag, thiab lwm yam; Kev vibration thiab cuam tshuam kev sim simulate lub zog sab nraud uas pcb yuav ntsib thaum siv tiag tiag, ntsuas nws lub zog thiab kev ntseeg siab. Tsuas yog los ntawm kev ua tiav thiab kev sim nruj me ntsis tuaj yeem ua kom ntseeg tau tias pcb ua tau raws li cov qauv tsim thiab kev ntseeg tau ntawm kev siv ib puag ncig.
