Kev xaiv cov khoom siv rau cov qauv nyuaj pcb xav tau kom ua tau raws li cov kev xav tau tshwj xeeb. Hauv kev sib txuas lus siab - zaus, nws yog ib qho tsim nyog yuav tsum siv siab - zaus thiab siab - ceev substrates. Lub dielectric qhov tsis tu ncua thiab qhov poob ntawm cov ntaub ntawv no yuav tsum tau tswj nruj me ntsis nyob rau hauv ib qho tshwj xeeb kom txo tau cov teeb liab kis tau tus mob, thiab lawv rhiab heev rau cov av noo thiab kub hloov pauv hauv qhov chaw ua haujlwm. Environmental parameters yuav tsum ruaj khov nyob rau hauv qhov chaw nqaim.
Rau qhov chaw ua haujlwm hnyav xws li kub thiab av noo, nws yog ib qho tsim nyog yuav tsum siv cov ntaub ntawv uas tiv taus kub thiab corrosion. Cov khoom siv ntawm cov khoom siv no yog qhov sib txawv ntawm cov ntaub ntawv zoo tib yam, thiab nws cov hardness thiab toughness indicators yog tshwj xeeb, uas yuav ua rau kom qhov nyuaj ntawm kev txiav, drilling thiab lwm yam txheej txheem, thiab muab tso rau pem hauv ntej cov kev xav tau siab dua rau cov hnav tsis kam thiab txiav qhov chaw ntawm cov cuab yeej ua.
Cov ntsiab lus tseem ceeb ntawm kev tsim khoom
txheej txheem lamination
Vim muaj kev nyuaj siab ntawm PCB cov qauv nrog ntau txheej txheej thiab cov ntaub ntawv tshwj xeeb, txheej txheem lamination yuav tsum tau tswj xyuas qhov kub thiab txias, siab, thiab lub sijhawm tsis ua haujlwm. Lub thermal expansion coefficients ntawm cov ntaub ntawv sib txawv sib txawv, thiab qhov tshwj xeeb kub siab lub sij hawm nkhaus yuav tsum tau tsim raws li cov yam ntxwv ntawm cov khoom kom tsis txhob muaj qhov tsis xws luag xws li interlayer sib cais thiab npuas. Cov khoom siv laminating yuav tsum muaj siab - qhov ntsuas qhov ntsuas qhov ntsuas qhov tseeb kom paub meej tias cov ntaub ntawv ntawm txhua txheej yog nruj sib xyaw ua ke thiab ua tau raws li qhov yuav tsum tau muaj ntawm lub zog thiab kev ua haujlwm ntawm hluav taws xob.
Circuit Court etching
Rau cov qauv zoo hauv Circuit Court, qhov concentration, kub, thiab etching lub sij hawm ntawm etching tov yuav tsum tau nruj me ntsis tswj. Vim qhov dav me me ntawm Circuit Court, tus nqi ntawm sab etching thaum lub sij hawm etching txheej txheem yuav tsum tau tswj nyob rau hauv ib tug me me ntau yam. Feem ntau, ntau cov txheej txheem etching yog siv los maj mam tshem tawm cov txheej tooj liab ntau dhau, kom ntseeg tau qhov tsis tu ncua ntawm cov npoo Circuit Court thiab tsis txhob luv luv lossis tawg hauv Circuit Court. Cov khoom siv etching yuav tsum muaj kev faib tawm ntawm cov etching tov thiab ruaj khov parameter tswj muaj peev xwm.
Drilling txheej txheem
Yuav kom ua tiav qhov kev sib txuas ntawm interlayer, qhov drilling aperture feem ntau yog me me, thiab qhov chaw raug yuav tsum tau mus txog qib micrometer. Mechanical drilling yuav tsum tau siv cov laum cov khoom uas muaj siab hardness thiab hnav tsis kam, thaum optimizing drilling ceev thiab pub tus nqi tsis. Rau cov qauv tshwj xeeb xws li faus qhov thiab qhov qhov muag tsis pom kev, laser drilling tshuab yuav tsum tau ua kom tiav siab - precision drilling los ntawm kev tswj lub laser zog ceev thiab lub sij hawm ua hauj lwm, xyuas kom meej lub qhov du phab ntsa thiab ua tau raws li qhov yuav tsum tau muaj kev sib txuas hluav taws xob.
kho saum npoo
Kev kho deg yuav tsum tau ua kom tau raws li qhov siab flatness, siab oxidation tsis kam, thiab siab weldability ntsuas. Ua ib qho piv txwv ntawm immersion kub, nws yog ib qho tsim nyog yuav tsum tau tswj xyuas qhov muaj pes tsawg leeg, qhov ceev tam sim no, thiab lub sij hawm plating ntawm cov tshuaj plating, xyuas kom cov tuab tuab ntawm cov txheej txheej deposit, thiab zam cov teeb meem xws li plating plating thiab tsis zoo kub plating. Rau cov qauv uas yuav tsum tau precision vuam, qhov roughness tom qab kho deg yuav tsum tau tswj nyob rau hauv ib tug tshwj xeeb ntau yam los xyuas kom meej qhov kev cia siab ntawm vuam thiab txo qhov kev pheej hmoo ntawm virtual pob qij txha.
Kev xeem txheej txheem specification
Kev kuaj pom ntawm cov qauv nyuaj pcb npog siab -kev ntsuas qhov tseeb hauv ntau yam. Ntxiv nrog rau kev soj ntsuam zoo li niaj zaus thiab kev ntsuas kev coj ua, kev sim impedance yuav tsum tau ua kom ntseeg tau tias kab impedance ua tau raws li tus qauv tsim; Ua cov teeb liab kev ntsuam xyuas kev ncaj ncees los ntsuas qhov kev ncaj ncees ntawm cov teeb liab nyob rau hauv siab - zaus kis; Ua kev ntsuas kub thiab qis qis, simulate qhov chaw ua haujlwm huab cua, thiab txheeb xyuas qhov ruaj khov ntawm cov qauv hauv qab qhov kub hloov pauv.
