Raws li cov khoom siv tseem ceeb rau kev ntsuas qhov tseeb, kev tswj hwm, thiab kev tsom xam, kev ua haujlwm ntawm cov twj paj nruag thiab cov ntsuas ntsuas yog ze ze rau kev ua haujlwm raug ntawm cov ntawv luam tawm sab hauv. Kev ua tiav ntawm cov ntawv luam tawm Circuit Court boards rau cov cuab yeej thiab cov ntsuas yuav tsum tau tshwj xeeb xws li kev ruaj ntseg siab, tsis tshua muaj suab nrov, thiab lub neej ntev. Cov nram qab no tsom xam cov ntsiab lus ua los ntawm ntau qhov ntev.
Cov khoom siv haum rau kev ntsuas precision
Cov cuab yeej thiab cov ntsuas feem ntau yuav tsum tau tswj cov hluav taws xob tsis muaj zog, yog li kev ua haujlwm rwb thaiv tsev thiab tiv thaiv - muaj peev xwm cuam tshuam ntawm cov ntaub ntawv pcb yog qhov tseem ceeb. High rwb thaiv tsev tiv thaiv substrates yuav tsum raug xaiv kom tsis txhob muaj teeb liab to lossis sab nraud cuam tshuam rau kev ntsuas qhov tseeb. Nyob rau tib lub sijhawm, kev ruaj ntseg ntawm dielectric tas li ntawm cov khoom yuav tsum tau tswj nruj me ntsis, tshwj xeeb tshaj yog nyob rau hauv ib puag ncig uas muaj qhov kub thiab txias hloov. Txawm tias me me hloov pauv hauv qhov dielectric tas li tuaj yeem ua rau lub teeb liab kis tau qeeb thiab cuam tshuam rau qhov ntsuas qhov tseeb ntawm qhov ntsuas. Tsis tas li ntawd, qee qhov siab -cov cuab yeej precision muaj cov kev cai tshwj xeeb rau cov thermal expansion coefficient ntawm cov ntawv luam tawm Circuit Court boards, uas yuav tsum tau xaiv qhov sib txuam substrates kom txo tau pcb deformation los ntawm qhov kub thiab txias hloov thiab tsis txhob cuam tshuam cov khoom tsis zoo los yog kev puas tsuaj rau circuits vim yog cov qauv deformation.
Cov txheej txheem layout uas txaus siab rau txoj haujlwm nyuaj
Muab faib layout ntawm ntau hom teeb liab
Instrumentation printed circuit boards feem ntau koom ua ke ntau hom teeb liab, xws li tsis muaj zog analog teeb liab, siab - ceev cov teeb liab, siab - lub zog tsav teeb liab, thiab lwm yam. Kev tsim qauv tsim qauv nruj me ntsis yuav tsum tau ua thaum ua kom pom tseeb ntawm cov cheeb tsam hauv Circuit Court ntawm ntau hom teeb liab. Piv txwv li, ib qho kev sib cais hauv av tau teeb tsa nruab nrab ntawm thaj chaw teeb liab analog thiab thaj chaw teeb liab digital kom tsis txhob muaj lub suab nrov ntawm - zaus ntawm cov teeb liab digital los cuam tshuam nrog kev ntsuas qhov tseeb ntawm lub teeb liab analog. Lub zog hluav taws xob ntau hauv cheeb tsam yuav tsum tau ceev kom deb ntawm qhov ntsuas qhov ntsuas hluav taws xob kom tsis txhob cuam tshuam ntawm tshav kub thiab hluav taws xob hluav taws xob ntawm cov hluav taws xob rhiab.
High density thiab refined thaiv
Nrog rau kev txhim kho txuas ntxiv ntawm kev ntsuas kev ua haujlwm, kev sib koom ua ke ntawm pcb nce ntxiv, thiab kev xaim hluav taws xob tau zoo heev. Thaum lub sij hawm ua, nws yog ib qho tsim nyog yuav tau ua kom zoo xaim, nrog txoj kab dav thiab qhov sib txawv ntawm qhov sib txawv me me kom tau raws li qhov yuav tsum tau ua ntawm ntau tus pin Cheebtsam. Nyob rau tib lub sijhawm, rau cov kab uas muaj cov cim tsis muaj zog, cov kab sib txawv yuav tsum tau siv los cuam tshuam kev cuam tshuam sab nraud los ntawm kev tsim kab sib luag, kom ntseeg tau tias muaj kev ncaj ncees. Txoj kev xaim yuav tsum tau luv luv kom ntau li ntau tau txhawm rau txo qhov poob thiab qeeb thaum lub teeb liab kis tau tus mob, tshwj xeeb tshaj yog rau siab - zaus moos teeb liab thiab cov teeb liab synchronization, yuav tsum muaj kev tswj xyuas qhov ntev ntawm kev xaim thiab impedance sib xws.
Xyuas kom ntev -lub sij hawm ruaj khov machining raug tswj
Micro qhov thiab zoo Circuit Court ua
Precision printed circuit boards rau instrumentation feem ntau yuav tsum tau lub installation ntawm ib tug loj tus naj npawb ntawm miniaturized Cheebtsam, xws li resistors thiab capacitors ntim rau hauv 01005, uas qhov chaw siab heev xav tau ntawm qhov precision ntawm pcb micro qhov ua. Txoj kab uas hla drilling yuav tsum tau tswj nyob rau hauv ib tug me me kam rau ua ntau yam, thiab lub roughness ntawm lub qhov phab ntsa yuav tsum tsis tshua muaj los xyuas kom meej txhim khu kev qha kev twb kev txuas ntawm cov tivthaiv pins thiab lub qhov phab ntsa. Kev ua haujlwm hauv Circuit Court yuav tsum ua kom cov kab dav qhov tseeb nyob rau hauv ± 5 μ m, cov npoo du tsis muaj burrs, thiab tsis txhob teeb liab distortion los yog luv luv Circuit Court txaus ntshai los ntawm Circuit Court tsis xws luag. Tsis tas li ntawd, rau circuits uas yuav tsum tau muaj peev xwm nqa tam sim no, nws yog ib qho tsim nyog yuav tsum tau tswj xyuas qhov tuab ntawm cov ntawv ci tooj liab kom paub meej tias nws lub peev xwm nqa tam sim no ua tau raws li cov qauv tsim, thaum tsis txhob muaj teeb meem kub dissipation tshwm sim los ntawm cov ntawv ci tooj liab ntau dhau.
Kev ntseeg tau guarantee ntawm interlayer interconnection
Lub interlayer interconnection zoo ntawm ntau- txheej precision pcb ncaj qha cuam tshuam rau kev ruaj ntseg ntawm qhov ntsuas. High precision laminating thev naus laus zis yuav tsum tau ua thaum ua haujlwm los xyuas kom meej tias qhov kev sib raug zoo ntawm txhua txheej yog tswj nyob rau hauv ib qho me me, zam qhov tsis zoo qhov muag tsis pom kev sib txuas los ntawm interlayer misalignment. Lub thickness uniformity ntawm lub interlayer rwb thaiv tsev txheej kuj yuav tsum tau nruj me ntsis tswj los tiv thaiv rwb thaiv tsev tawg los ntawm lub zos hluav taws xob teb zog ntau heev. Rau interlayer kev sib txuas ntawm cov teeb liab tseem ceeb, kev sib xyaw ntawm cov kauj ruam los yog qhov muag tsis pom kev faus qhov yuav siv tau los txo cov impedance transients nyob rau hauv txoj kev teeb liab kis tau tus mob thiab ua kom ruaj khov teeb liab kis tau tus mob.
Kev tiv thaiv rau kev cuam tshuam nrog ib puag ncig nyuaj
Kev tiv thaiv corrosion thiab tiv thaiv - kev laus kev kho mob
Qee cov cuab yeej thiab cov ntsuas yuav tsum tau ua haujlwm nyob rau hauv ib puag ncig uas muaj av noo, plua plav, lossis muaj cov roj corrosive, yog li kev tiv thaiv pcb yog qhov tseem ceeb. Ntxiv nrog rau cov txheej txheem txheej txheej txheej txheem, tshwj xeeb los tiv thaiv- cov txheej txheem corrosion xws li polyimide txheej tuaj yeem siv tau, uas tuaj yeem tsis tsuas yog cais cov dej vapor thiab cov tshuaj corrosive, tab sis kuj tiv taus qee qhov kev hloov pauv kub, ua kom lub sijhawm ntev - lub sijhawm ua haujlwm ruaj khov ntawm cov ntawv luam tawm Circuit Court boards hauv ib puag ncig hnyav. Rau ntev - siv cov cuab yeej precision, kev laus tiv thaiv ntawm pcb substrates yuav tsum tau soj ntsuam nruj me ntsis kom tsis txhob muaj kev ua haujlwm degradation los ntawm cov khoom laus thiab txuas ntxiv lub neej kev pab cuam ntawm lub cuab yeej.
Optimization thiab ua cov txheej txheem kub dissipation
Thaum lub sijhawm ua haujlwm ntev -, qee yam ntawm cov cuab yeej thiab cov ntsuas yuav ua kom sov. Yog tias kub ntau dhau, nws yuav cuam tshuam rau kev ua haujlwm ntawm pcb thiab cov khoom nyob ib puag ncig. Thaum lub sijhawm ua haujlwm, cov kab hluav taws xob hluav taws xob tshwj xeeb tuaj yeem tsim tau, xws li tso thaj chaw loj ntawm cov ntawv ci tooj liab nyob rau hauv siab - cov khoom siv hluav taws xob lossis siv cov khoom siv hluav taws xob sib txuas, txhawm rau txhim kho cov hluav taws xob hluav taws xob thiab kev nthuav dav. Rau siab -cov cuab yeej ntsuas qhov ntsuas kub qhov tseeb, pcb hluav taws xob dissipation tsim kuj tseem tsim nyog los txo qhov cuam tshuam ntawm nws tus kheej cua sov ntawm qhov ntsuas kub thiab ua kom qhov ntsuas qhov tseeb.
Kev ua tau zoo calibration thiab validation
Muaj tseeb calibration ntawm hluav taws xob tsis
Tom qab qhov precision pcb ua cov twj paj nruag thiab cov ntsuas ua tiav, cov khoom siv hluav taws xob sib txawv yuav tsum tau ua. Los ntawm kev siv cov cuab yeej tshwj xeeb kev ntsuas qhov tseeb, qhov nce, bandwidth, linearity thiab lwm yam tsis zoo ntawm txhua lub voj voog module raug ntsuas kom raug thiab kho kom ntseeg tau tias lawv ua tau raws li cov qauv tsim ntawm lub ntsuas. Rau cov circuits uas muaj cov teeb liab tsis muaj zog, nws yog ib qho tsim nyog yuav tsum tau tsom mus rau kev sim lawv cov suab nrov coefficient. Los ntawm optimizing grounding thiab shielding, lub suab nrov tuaj yeem tswj tau ntawm qib qis heev kom ntseeg tau tias lub cuab yeej muaj peev xwm los ntes cov cim me me.
Long-term stability xeem
Tsis zoo li cov ntawv luam tawm tsis tu ncua, cov ntawv luam tawm Circuit Court boards rau kev ntsuas yuav tsum tau ntev -kev ntsuas kev ruaj ntseg los xyuas lawv qhov kev ntseeg tau. Raws li kev simulated ua haujlwm ib puag ncig, pcb raug kuaj ua haujlwm tsis tu ncua rau ntau pua lossis ntau txhiab teev los saib xyuas cov kev hloov pauv ntawm nws cov khoom siv hluav taws xob. Yog hais tias qhov parameter drift tshaj qhov kev tso cai, nws yog ib qho tsim nyog yuav tsum tau soj ntsuam cov laj thawj thiab ua kom zoo dua cov txheej txheem ua haujlwm kom ntseeg tau tias pcb tswj kev ua haujlwm ruaj khov thoob plaws tag nrho lub neej kev pab cuam ntawm lub ntsuas.
