E-test ntawm pcb

Thaum lub sij hawm tsim cov txheej txheem ntawm cov ntawv luam tawm Circuit Board, nws yog ib qho tsim nyog yuav tsum tau ua rau sab nraud tuaj yeem ua rau hluav taws xob tsis zoo xws li luv luv Circuit Court, qhib circuits, thiab to. Tsis tas li ntawd, pcb boards txuas ntxiv mus rau qhov siab ceev, qhov sib nrug zoo, thiab ntau theem. Yog tias qhov teeb meem tsis raug tshuaj xyuas thiab kho raws sijhawm, tso cai rau lawv ntws mus rau hauv cov txheej txheem yuav ua rau muaj kev cuam tshuam ntau dua. Yog li ntawd, ntxiv rau kev txhim kho cov txheej txheem tswj, kev txhim kho kev sim tshuab kuj tseem tuaj yeem muab cov tuam txhab PCB nrog cov kev daws teeb meem los txo cov nqi seem thiab txhim kho cov khoom yiel.

 

Cov kev cai dav dav rau kev kuaj hluav taws xob

Kev ntsuam xyuas hluav taws xob feem ntau yog kuaj cov conductivity thiab rwb thaiv tsev ntawm pcb. Kev ntsuas txuas ntxiv yog hais txog kev ntsuas seb tus nqi ntawm cov nodes nyob rau hauv tib lub network yog tsawg dua qhov txuas txuas mus los txiav txim seb txoj kab puas raug txiav, feem ntau hu ua qhib Circuit Court; Kev ntsuas rwb thaiv tsev hais txog kev txiav txim siab seb puas muaj qhov luv luv hauv lub rwb thaiv tsev network los ntawm kev ntsuas seb tus nqi tiv thaiv ntawm qhov sib txawv network no ntau dua li qhov kev ntsuas hluav taws xob.

 

Cov yam ntxwv cuam tshuam rau PCB E-testing

 

Nrog rau kev nce ntawm Circuit Court ceev, qhov nyuaj ntawm kev kuaj hluav taws xob kuj nce ntxiv, thiab cov thev naus laus zis tshiab tau tshwm sim los tiv thaiv kev txhim kho ntawm PCB kev lag luam. Cov yam tseem ceeb uas ua rau kom qhov nyuaj ntawm kev sim yog:

 

a. Qhov loj me ntawm lub substrate nto

b. PAD span (Pitch)

c. Txo qhov sib nrug ntawm cov xov hlau txo qhov aperture ntawm qhov kev coj ua

d. PAD deg indentation txwv

e. Kev txhim kho ntawm kev ntsuas thaiv qhov tseeb qhov yuav tsum tau ua

f. Cov kev xav tau nrawm dua, thiab lwm yam

 

Kev faib tawm thiab cov ntsiab lus ntawm Kev Ntsuas Hluav Taws Xob Kev Ua Haujlwm Zoo

 

Kev ntsuas hluav taws xob PCB tuaj yeem muab faib ua ob pawg hauv cov hauv paus ntsiab lus: txoj kev ntsuas kev tiv thaiv thiab kev ntsuas kev ntsuas kev ntsuas.

 

Txoj kev ntsuas kev tiv thaiv kuj tseem tuaj yeem muab faib ua ob qhov kev xeem davhlau ya nyob twg thiab plaub lub davhlau ya nyob twg, ntawm qhov uas plaub lub davhlau ya nyob twg xeem txoj kev yog qhov ntau tshaj plaws; Raws li seb qhov kev sojntsuam kuaj puas muaj kev sib cuag nrog PCB, nws tuaj yeem muab faib ua cov qauv kev sib cuag thiab cov qauv tsis sib cuag.

 

Cov txheej txheem thiab cov khoom siv rau kev ntsuas hluav taws xob

 

Cov qauv kev sim muaj xws li kev mob siab rau, universal grid, ya sojntsuam, tsis sib cuag electron beam, conductive daim ntaub (adhesive), capacitive, thiab txhuam txhuam. Ntawm lawv, cov cuab yeej siv feem ntau yog cov tshuab kuaj mob siab, cov tshuab ntsuas thoob ntiaj teb, thiab cov tshuab ntsuas ya davhlau.

 

Cov txheej txheem ntsuas hluav taws xob hauv Circuit Court board yog ib qho tseem ceeb thiab cov txheej txheem tseem ceeb hauv kev tsim cov khoom siv hluav taws xob. Ua kom tiav cov txheej txheem luam ntawv Circuit Court board hluav taws xob kuaj cov txheej txheem tuaj yeem ua kom ruaj khov thiab txhim khu kev qha kev sib txuas ntawm cov khoom siv hluav taws xob, thiab txhim kho cov khoom zoo thiab kev ntseeg siab.

Sihui Fuji hais txog kev lag luam lub tswv yim ntawm kev ua tau zoo ua ntej thiab txiav txim siab tiv thaiv txhua yam khoom tsis raug xa mus rau cov neeg siv khoom. Rau cov khoom kuaj pom muaj teeb meem, qee qhov ntawm lawv yuav raug siv rau kev sim tshuaj ntsuam xyuas thiab tshuaj xyuas kom pom qhov ua rau muaj qhov tsis xws luag, thaum lwm qhov yuav raug tshem tawm ncaj qha, khov kho tiv thaiv qhov tsis xws luag los ntawm kev ntws tawm mus rau cov neeg siv khoom, hais kom tsis txhob raug tsim khoom. , tsis ntws tawm qhov tsis xws luag, thiab tsis ua teeb meem rau cov neeg siv khoom.
