PCB qhov chaw nyob yog qhov txuas tseem ceeb heev hauv PCB txheej txheem tsim los txiav txim siab qhov tshwj xeeb ntawm PCB los ntawm qhov. Lub luag haujlwm ntawm qhov chaw nyob yog luam tawm lub rooj tsav xwm hauv Circuit Court tsim cov txheej txheem. PCB txoj hauv kev tso qhov tso rau txoj hauv kev muaj ntau yam, feem ntau yog raws qhov sib txawv ntawm qhov tseeb qhov yuav tsum tau ua. Qhov chaw tso rau ntawm lub rooj sib tham luam tawm yuav tsum muaj cov cim tshwj xeeb kos duab. Thaum cov tseev kom muaj tsis siab, qhov sib dhos loj dua nyob rau hauv daim ntawv luam tawm Circuit Board tuaj yeem siv tau.

Txhawm rau txhawm rau txhawm rau txhawm rau luam tawm Circuit board board drilling thiab milling cov duab ruaj ruaj, nrog rau kev sim online yooj yim, ntau lub tuam txhab tsim khoom hauv Circuit Court vam tias cov neeg siv los tsim peb lub qhov tsis sib thooj ntawm PCB, tso lub qhov yog feem ntau tsim rau hauv qhov tsis yog hlau, qhov taub ntawm mm sau mm. Smmo yog lub rooj tsavxwm nruj, tsawg kawg yuav tsum muab ob lub qhov tso, thiab muab tso rau ntawm kab pheeb ces kaum. Yog tias koj ua lub rooj sib tham, koj tseem tuaj yeem xav txog lub rooj sib dhos ua lub PCB, tag nrho cov laug cam ntev li ntev tau muaj peb qhov tso rau qhov. Yog tias tus neeg siv tsis tso, lub chaw tsim khoom hauv Circuit Court yuav txiav ntxiv rau ntawm qhov tsis cuam tshuam rau kab, lossis siv cov qhov tsis muaj hlau uas twb muaj lawm hauv pawg thawj coj raws li qhov chaw tso.

Qhov chaw nyob qhov twg

Cov cuab yeej sib cuam tshuam cov cuab yeej thiab cov txuas txuas feem ntau yog cov khoom siv sib txuas. Qhov dhau los ntawm txoj kab uas hla ntawm cov cuab yeej tso tawm yog loj dua tus pin txoj kab uas hla ntawm 8 ~ 20mil, thiab qhov nkag nkag tau zoo yog qhov zoo thaum siv vuam. Nws yuav tsum raug sau tseg tias muaj qhov yuam kev hauv lub qhov taub ntawm lub rooj tsav xwm hauv Circuit Court, thiab qhov ua yuam kev kwv yees yog ± 0.05mm. 0.05mm yog hom laum ntawm txhua ntu, thiab 0.lmm yog hom laum ntawm txhua ntu yog tias txoj kab uas hla siab dua 3.20mm. Yog li ntawd, thaum tsim lub aperture ntawm lub cuab yeej, chav yuav tsum hloov pauv mus rau hauv millimeters, thiab lub qhov taub yuav tsum tau tsim los ua ib qho zauv ntau ntawm 0.05. Lub phaj phaj teeb tsa cov cuab yeej drilling loj raws li cov ntaub ntawv drilling muab los ntawm tus neeg siv. Qhov cuab yeej siv me me feem ntau yog 0.1 ~ 0.15 loj dua qhov tsim qhov uas tus neeg siv yuav tsum tau ua. Txoj kab uas hla ntawm mmo tsim yuav tsum loj dua qhov me, thiab qhov yuav tsum tau ua siab ntev yuav tsum yog loj dua qhov me. Yog tias nws yog cov cuab yeej crimping, lub qhov taub yuav tsum tsis txhob nce ntxiv, raws li cov ntaub ntawv pom zoo tsim, thiab hauv cov lus qhia los piav qhia dab tsi yog crimping ntaus ntawv, yog li cov chaw tsim khoom hauv Circuit Court tuaj yeem sim tswj qhov ua yuam kev hauv cov txheej txheem ntawm kev ua board, kom zam qee qhov teeb meem tsis tsim nyog.

Drilling hom tau muab faib ua cov qhov hlau thiab qhov uas tsis yog hlau. Muaj cov tooj liab los nag hauv phab ntsa ntawm lub qhov hlau, uas tuaj yeem ua lub luag haujlwm coj ua thiab yog sawv cev los ntawm PTH. Tsis muaj tooj liab hauv lub qhov phab ntsa ntawm lub qhov uas tsis yog hlau, yog li nws tsis tuaj yeem siv hluav taws xob. Nws tau qhia los ntawm NPTH. Qhov sib txawv ntawm txoj kab nruab nrab sab hauv thiab txoj kab uas hla ntawm lub qhov taub uas hla ntawm lub pob zeb yuav tsum muaj ntau dua 20mil, txwv tsis pub lub vuam ntiv nplhaib ntawm lub ncoo me me rau kev ua thiab tsis cuam tshuam rau vuam. Yog tias muaj kev tso cai, lub qhov taub tuaj yeem tsim los ua lub vojvoog ntawm lub ncoo. Qhov siab tshaj plaws txoj kab uas hla ntawm lub qhov hlau yog 6.35mm, thiab qhov siab tshaj qhov taub ntawm qhov tsis yog hlau yog 6.5mm. Lub qhov taub hlau yuav tsum tsis txhob tsim rau ntawm txoj kab contour. Lub qhov ntug yuav tsum yog ntau dua 1 hli deb ntawm txoj kab sib tw. Cobalt qhov hnyav qhov yooj yim puas rau qhov laum, yog li yuav tsum zam kom ntau li ntau tau. Tsis muaj vuam thiab tsis muaj qhov hluav taws xob uas tsis yog xim hlau, qhov tuaj yeem tsim rau hauv tus yam ntxwv ntawm cov hlau tsis siv hlau vuam phaj qhov tsis xav tau tsim, kab lossis tooj liab ntawv tsawg kawg 1 mmo drilling qhov ntug deb raws li cov duab tuaj yeem muab faib ua qhov ncig thiab lub qhov plaub fab, qhov zoo ib yam rau qhov hloov puag ncig, lub qhov qhov yog me ntsis raws li cov txheej txheem tau teev tseg los ntawm ntau lub sijhawm ntawm kev khawb, yog li lub qhov lub qhov tsim tsim kom zoo tshaj plaws yog ob zaug qhov dav, Thiab qhov dav tsis tsawg dua 0.8 hli, tsawg li ntau tau los tsim cov duab plaub.

PCB qhov tso rau qhov yuav tsum tau ua:

Kev tsim kho ntawm PCB tsim kev lag luam tau dhau los ua neeg paub tab, yog li qhov xav tau rau PCB qhov chaw nyob kuj tseem zoo heev. Qhov muab tso rau qhov yuav tsum ua tau raws li cov hauv qab no.

1. Nruab qhov tsawg kawg yog ob qhov tso rau ntawm kab pheeb ces kaum ntawm lub rooj tsavxwm.

2. Tus qauv qhov siab ntawm qhov tso qhov yog 3.2mm _+0.05mm.

3, rau cov khoom lag luam sib txawv ntawm cov tuam txhab veneer tseem tuaj yeem siv qhov nyiam hauv qab no: 2.8mm ± 0.05mm, 3.0mm ± 0.5mm, 3.5mm ± 0.5mm thiab 4.5mm ± 05mm. Rau cov laug cam sib txawv ntawm cov khoom qub (xws li DT board thiab PP board ntawm ZXJlO), yog tias PCB muaj tib qhov loj me, qhov tso qhov yuav tsum zoo ib yam.

4. Qhov muab tso rau qhov yog lub teeb pom kev, uas yog, tsis yog xim hlau los ntawm lub qhov (tshwj tsis yog rf board).

5. Yog tias lub qhov uas twb muaj lawm (tshwj tsis yog lub qhov ntsaws qhov ntsaws qhov ntsaws) ua tau raws li qhov xav tau saum toj no, tsis tas yuav teeb lwm qhov chaw.

Qee qhov kev qhia tshwj xeeb thiab qhov yuav tsum tau ua rau qhov tso qhov:

1. Txoj kab nruab nrab qhov yuam kev ntau ntawm qhov tso qhov yog feem ntau tsis pub dhau 0.01 hli. Yog tias qhov ua yuam kev loj hauv PCB chav tsim khoom, nws yuav ua rau tsis zoo ntawm kev sojntsuam thiab kev ua haujlwm tsis raug ntawm qhov txuas txuas mus rau lub tshuab tsis siv neeg.

2, txoj kab uas hla ntawm qhov yuav tsum tau ua qhov chaw: sim ua qis dua 3mm, yog li cov kab ntawv yuav tsis hloov pauv, loj dhau thiab tsis yooj yim rau kev khiav lag luam.

3, muab tso rau qhov PCB network nrug: ntau dua 1MM, yog li kev teeb tsa kev ua haujlwm tsis yooj yim rau luv Circuit Court, tseem yuav tsis ua kev puas tsuaj rau cov khoom lag luam.

4, hom kev tso qhov: qhov tso qhov yog feem ntau xav tau kev tswj cov khoom siv tooj liab uas tsis pom, yog li nws tsis tuaj yeem txuas nrog lub Circuit Court ntawm lub rooj tsavxwm thiab raug siab dua.

5, kev teeb tsa lub zais zis: yuav tsum nyob hauv PCBA plaub fab lossis kab pheeb ces kaum, txhawm rau tsim kom muaj ntau lub ntsiab lus dav hlau tso rau, tso qhov tseeb, nyob deb dua qhov zoo dua.

6, qhov nrug nruab nrab ntawm qhov chaw tso thiab qhov ntsuas yuav tsum yog yam tsawg 2 hli, txhawm rau tiv thaiv qhov tsis raug luv luv hauv kev sim.

7. Qhov nrug nruab nrab ntawm qhov muab tso rau qhov thiab ntug ntawm phaj yog tsawg kawg 2mm, uas tsis yooj yim rau tawg thaum ua kom ntseeg tau lub zog ntawm PCBA.
