Vim li cas PCB Boards Ua Impedance?

Vim li cas PCB boards ua impedance?

Impedance - qhov tseeb, yog hais txog qhov tsis kam thiab qhov tsis sib xws ntawm khub ntawm reactance, vim hais tias cov kab PCB los txiav txim siab lub plug-in installation ntawm cov khoom siv hluav taws xob, plug-in tom qab kev txiav txim siab ntawm conductivity thiab teeb liab kis tau tus mob thiab lwm yam teeb meem, yog li ntawd. Nws yog inevitable tias qhov qis impedance qhov zoo dua, qhov resistivity yuav tsum qis dua ib square centimeter 1 × 10 ntawm qhov rho tawm 6 zaug hauv qab no.

Ntawm qhov tod tes, PCB board nyob rau hauv cov txheej txheem ntau lawm mus los ntawm tooj liab sinking, tin plating (los yog chemical plating, los yog thermal spray tin), connectors thiab lwm qhov chaw ntawm qhov txuas thiab cov ntaub ntawv siv nyob rau hauv qhov txuas no yuav tsum xyuas kom meej tias hauv qab. ntawm cov resistivity, thiaj li yuav xyuas kom meej tias tag nrho impedance ntawm PCB board yog tsawg nyob rau hauv thiaj li yuav ua tau raws li qhov yuav tsum tau ntawm cov khoom zoo, los yog lwm yam Circuit Court board yuav tsis ua hauj lwm ib txwm.

Kev lag luam hluav taws xob tag nrho, PCB Circuit Court board Hoobkas nyob rau hauv tin-plating txuas yog qhov teeb meem tshaj plaws, yog qhov cuam tshuam ntawm impedance ntawm cov kev sib txuas tseem ceeb, vim hais tias lub Circuit Court board tin-plating txuas, yog tam sim no nrov mus cuag lub hom phiaj ntawm tin-plating siv chemical tin-plating technology, tab sis peb yog cov khoom siv hluav taws xob hauv kev lag luam raws li cov neeg tau txais kev lag luam hauv hluav taws xob, lossis PCB pawg thawj coj saib kev tsim khoom thiab kev lag luam rau ntau tshaj 10 xyoo ntawm kev sib cuag thiab kev soj ntsuam.

Rau kev lag luam hluav taws xob, raws li txoj kab ntawm kev tshawb nrhiav, qhov tsis muaj zog tshaj plaws ntawm cov tshuaj tin txheej yog yooj yim rau discolor (ob qho tib si yooj yim oxidation los yog deliquescence), tsis zoo brazing ua rau nyuaj rau welding, impedance siab dhau ua rau tsis zoo conductivity lossis tag nrho lub rooj tsavxwm kev ua tau zoo tsis ruaj khov, yooj yim kom loj hlob tin whiskers ua rau PCB kab luv luv lossis txawm tias hlawv lossis hluav taws kub.

Cov kab tseem ceeb ntawm PCB Circuit Board yog tooj liab ntawv nyiaj, tooj liab ntawv ci hauv cov pob qij txha yog cov tin txheej, thiab cov khoom siv hluav taws xob yog los ntawm cov tshuaj txhuam (los yog cov kab solder) welded rau sab saum toj ntawm cov tin txheej, qhov tseeb, solder muab tshuaj txhuam hauv melting lub xeev ntawm soldering rau cov khoom siv hluav taws xob thiab tin plating txheej ntawm tin hlau (xws li, conductive hlau monomers), yog li nws tuaj yeem ua tau yooj yim thiab qhia meej tias cov khoom siv hluav taws xob yog plated nrog tin plating txheej nrog hauv qab ntawm PCB. board thiab ces cov ntawv ci tooj liab Connection.

Yog li qhov purity ntawm tin plating txheej thiab nws impedance yog tus yuam sij;tab sis tsis yog ua ntej kev sib txuas ntawm cov khoom siv hluav taws xob, ncaj qha nrog lub ntsuas ntsuas kom pom qhov impedance, qhov tseeb, qhov ntsuas ntsuas ntsuas (los yog hu ua meter cwj mem) xaus kuj yog los ntawm thawj kev sib cuag nrog lub rooj tsav xwm hauv Circuit Court board hauv qab ntawm qhov chaw. ntawm cov ntawv ci tooj liab ntawm tin plating txheej thiab tom qab ntawd nrog rau hauv qab ntawm PCB board tooj liab ntawv ci los txuas rau tam sim no.Yog li cov tin txheej yog tus yuam sij, yog tus yuam sij rau cuam tshuam rau qhov impedance thiab cuam tshuam rau kev ua haujlwm ntawm lub rooj tsavxwm Circuit Court board, tab sis kuj yooj yim kom tsis quav ntsej qhov tseem ceeb.

Ntxiv nrog rau cov hlau monomers, lawv cov tebchaw yog cov neeg ua haujlwm tsis zoo ntawm cov hluav taws xob lossis txawm tias tsis yog-conductive (uas kuj yog tshwm sim los ntawm kev muaj peev xwm faib tawm hauv kab lossis kev sib kis ntawm tus yuam sij), yog li cov tin plating txheej nyob rau hauv lub xub ntiag ntawm no. hom zoo li cov khoom siv hluav taws xob thiab cov khoom siv tsis zoo lossis cov khoom sib xyaw ntawm cov tin, nws cov kev tiv thaiv tau npaj txhij los yog yav tom ntej oxidation, cov tshuaj tiv thaiv electrolytic ntawm cov dej noo thiab nws cov kev sib raug zoo thiab impedance yog qhov siab heev (yuav ua rau muaj kev cuam tshuam rau theem lossis teeb liab kis ntawm cov digital circuits. ).theem lossis teeb liab kis tau tus mob hauv digital circuits), thiab nws cov yam ntxwv impedance tsis zoo ib yam.Qhov no cuam tshuam rau kev ua haujlwm ntawm lub rooj tsav xwm Circuit Court thiab lub tshuab tag nrho.

Nyob rau hauv cov nqe lus ntawm tam sim no kev sib raug zoo tsim tshwm sim, pcb board nyob rau hauv qab ntawm cov khoom plating thiab kev ua tau zoo yog cuam tshuam rau PCB board yam ntxwv ntawm impedance ntawm qhov tseem ceeb tshaj plaws vim li cas thiab qhov ncaj qha yog vim li cas, tab sis kuj yog vim lub plating nrog cov laus. thiab ya raws electrolysis ntawm qhov sib txawv ntawm impedance kom nws impedance los tsim ib qho kev txhawj xeeb txog kev cuam tshuam ntawm qhov cuam tshuam ntawm ntau qhov zais thiab hloov tau, thiab lub ntsiab yog vim li cas rau nws qhov zais zais nyob hauv cov hauv qab no: thawj tsis tuaj yeem pom los ntawm cov qhov muag liab qab, thiab qhov thib ob tsis tuaj yeem ntsuas qhov tsis tu ncua, vim tias nws muaj nrog lub sijhawm thiab ambient humidity thiab kev hloov ntawm impedance ntawm lub rooj tsavxwm thiab kev ua haujlwm ntawm lub tshuab.Vim tias nws muaj qhov sib txawv nrog kev hloov ntawm lub sijhawm thiab ib puag ncig cov av noo, yog li nws yog ib qho yooj yim uas yuav tsis quav ntsej.
