Dab tsi yog PCB vias, dig muag vias, faus vias, drilled vias

Ntawm lub qhov (VIA), cov kab ntawv tooj liab ntawm cov kab hluav taws xob sib txawv hauv cov txheej txheem sib txawv ntawm lub rooj tsav xwm hluav taws xob tau ua los yog txuas nrog lub qhov zoo li no, tab sis nws tsis tuaj yeem muab tso rau hauv tooj liab plated qhov ntawm cov khoom siv lead ua lossis lwm yam khoom siv ntxiv. Lub rooj tsav xwm luam tawm (PCB) yog tsim los ntawm kev sib tw thiab sib sau ntau txheej ntawm tooj liab ntawv nyiaj. Qhov laj thawj yog vim li cas cov txheej txheem tooj liab tsis tuaj yeem sib txuas lus yog vim txhua txheej ntawm cov ntawv ci tooj liab tau npog nrog cov txheej txheem insulating, yog li lawv yuav tsum tau cia siab rau vias rau cov teeb liab sib txuas, yog li muaj Suav vias. lub npe.

Cov txheej txheem tsim khoom no tsis tuaj yeem ua tiav los ntawm kev sib txuas ntawm lub rooj tsav xwm hauv Circuit Court thiab tom qab ntawd qhov drilling qhov. Nws yog ib qho tsim nyog los ua cov haujlwm drilling ntawm cov txheej txheem ib leeg. Ua ntej, cov khaubncaws sab nraud povtseg yog ib feem sib koom ua ke thiab tom qab ntawd electroplated, thiab thaum kawg tag nrho lawv tau sib koom ua ke. Txij li thaum cov txheej txheem ua haujlwm yog ntau zog tshaj qhov qub vias thiab qhov muag tsis pom, tus nqi kuj tseem kim tshaj plaws. Cov txheej txheem tsim khoom no feem ntau tsuas yog siv rau high-density circuit boards, nce qhov chaw siv ntawm lwm cov khaubncaws sab nraud povtseg.

Drilling yog ib qho tseem ceeb heev nyob rau hauv cov txheej txheem luam tawm Circuit Board (PCB). Qhov kev nkag siab yooj yim ntawm kev drilling yog tho qhov yuav tsum tau vias ntawm tooj liab clad laminate, uas muaj kev ua haujlwm ntawm kev muab hluav taws xob sib txuas thiab kho cov khoom siv. Yog tias qhov kev ua haujlwm tsis raug, yuav muaj teeb meem hauv cov txheej txheem ntawm lub qhov, thiab cov cuab yeej tsis tuaj yeem kho ntawm lub rooj tsav xwm hauv Circuit Court, uas yuav cuam tshuam rau kev siv lub rooj tsavxwm Circuit Court yam tsawg, los yog ua rau tag nrho lub rooj tsavxwm scrapped, yog li qhov drilling. txheej txheem tseem ceeb heev.

Lub qhov dhau ntawm lub rooj tsav xwm Circuit Court yuav tsum dhau los ntawm lub qhov ntsaws kom tau raws li cov neeg siv khoom xav tau. Nyob rau hauv kev hloov cov txheej txheem ntawm txhuas daim ntawv ntsaws qhov, lub qhov ncauj qhov ntswg thiab ntsaws qhov ntawm lub rooj tsav xwm Circuit Court nto yog ua tiav nrog ib tug dawb mesh kom cov ntau lawm ruaj khov thiab zoo dua txhim khu kev qha. , nws yog qhov zoo tshaj plaws los siv. Ntawm qhov pab circuits txuas thiab coj mus rau ib leeg. Nrog rau txoj kev loj hlob sai ntawm kev lag luam hluav taws xob, cov kev xav tau siab dua tau muab tso rau ntawm cov txheej txheem tsim khoom thiab kev siv thev naus laus zis ntawm cov ntawv luam tawm Circuit Board (PCBs).

Cov txheej txheem ntawm lub qhov ntsaws ntsaws tau los ua, thiab cov kev cai hauv qab no yuav tsum tau ua raws tib lub sijhawm:

1. Tsuas yog yuav tsum muaj tooj liab hauv lub qhov, thiab lub npog ntsej muag tuaj yeem ntsaws los yog tsis tau;
2. Yuav tsum muaj tin-lead nyob rau hauv lub qhov, thiab muaj ib tug tej yam thickness yuav tsum tau (4um), kom tsis txhob solder daim npog qhov ncauj number case nkag mus rau hauv lub qhov, ua rau tin hlaws dai nyob rau hauv lub qhov;
3. Lub qhov ntawm lub qhov yuav tsum muaj solder tiv thaiv number case plug qhov, yog opaque, yuav tsum tsis txhob muaj tin rings thiab tin hlaws, thiab yuav tsum tiaj tus.

Nws yog los txuas rau sab nraud ntawm lub rooj tsav xwm luam tawm (PCB) thiab cov txheej sab hauv uas nyob ib sab nrog plated qhov. Txij li thaum sab nraud tsis tuaj yeem pom, nws yog hu ua blind pass. Txhawm rau ua kom qhov chaw siv qhov chaw nruab nrab ntawm pawg thawj coj saib Circuit Court txheej, qhov qhov muag tsis pom kev tuaj yeem ua ke. Lub qhov muag tsis pom kev yog ib lub qhov ntawm lub qhov rau saum npoo ntawm cov ntawv luam tawm

Qhov muag tsis pom qhov nyob rau saum thiab hauv qab ntawm lub rooj tsavxwm Circuit Court thiab muaj qhov tob. Lawv yog siv los txuas cov kab hluav taws xob saum npoo mus rau sab hauv Circuit Court hauv qab no. Qhov tob ntawm lub qhov feem ntau muaj ib qho piv txwv (aperture). Txoj kev tsim khoom no xav tau kev saib xyuas tshwj xeeb, thiab qhov tob tob yuav tsum yog txoj cai. Yog tias koj tsis mloog, nws yuav ua rau muaj teeb meem hauv electroplating hauv lub qhov. Yog li ntawd, ob peb lub Hoobkas yuav siv txoj kev tsim khoom no. Qhov tseeb, nws kuj tseem tuaj yeem tho qhov rau cov txheej txheej hauv Circuit Court uas yuav tsum tau txuas ua ntej, thiab tom qab ntawd muab cov nplaum nplaum ua ke thaum kawg, tab sis yuav tsum tau muaj ntau qhov chaw thiab cov khoom sib dhos.

Lub qhov faus yog ib qho kev sib txuas ntawm txhua txheej txheej hauv Circuit Court board (PCB), tab sis nws tsis txuas nrog txheej txheej, uas yog, tsis muaj qhov txuas mus rau saum npoo ntawm lub rooj tsav xwm Circuit Court.

Cov txheej txheem tsim khoom no tsis tuaj yeem ua tiav los ntawm kev sib txuas ntawm lub rooj tsav xwm hauv Circuit Court thiab tom qab ntawd qhov drilling qhov. Nws yog ib qho tsim nyog los ua cov haujlwm drilling ntawm cov txheej txheem ib leeg. Ua ntej, cov khaubncaws sab nraud povtseg yog ib feem sib koom ua ke thiab tom qab ntawd electroplated, thiab thaum kawg tag nrho lawv tau sib koom ua ke. Txij li thaum cov txheej txheem ua haujlwm yog ntau zog tshaj qhov qub vias thiab qhov muag tsis pom, tus nqi kuj tseem kim tshaj plaws. Cov txheej txheem tsim khoom no feem ntau tsuas yog siv rau high-density circuit boards, nce qhov chaw siv ntawm lwm cov khaubncaws sab nraud povtseg.

Drilling yog ib qho tseem ceeb heev nyob rau hauv cov txheej txheem luam tawm Circuit Board (PCB). Qhov kev nkag siab yooj yim ntawm kev drilling yog tho qhov yuav tsum tau vias ntawm tooj liab clad laminate, uas muaj kev ua haujlwm ntawm kev muab hluav taws xob sib txuas thiab kho cov khoom siv. Yog tias qhov kev ua haujlwm tsis raug, yuav muaj teeb meem hauv cov txheej txheem ntawm lub qhov, thiab cov cuab yeej tsis tuaj yeem kho ntawm lub rooj tsav xwm hauv Circuit Court, uas yuav cuam tshuam rau kev siv lub rooj tsavxwm Circuit Court yam tsawg, los yog ua rau tag nrho lub rooj tsavxwm scrapped, yog li qhov drilling. txheej txheem tseem ceeb heev.
