Dab tsi yog qhov kev faib tawm thiab muaj pes tsawg leeg ntawm PCB Circuit Board vias?

Vias yog ib feem tseem ceeb ntawm PCB Circuit Court boards, thiab tus nqi ntawm drilling feem ntau yog 30 feem pua ​​​​rau 40 feem pua ​​ntawm cov nqi ntawm PCB manufacturing. Yooj yim muab, txhua qhov ntawm PCB tuaj yeem hu ua viav vias.

1. Kev faib tawm ntawm vias

Hais txog kev ua haujlwm, vias tuaj yeem muab faib ua ob pawg: ib qho yog siv rau kev sib txuas hluav taws xob ntawm txheej txheej; lwm qhov yog siv los kho lossis tso cov khoom siv. Nyob rau hauv cov nqe lus ntawm cov txheej txheem, vias tau muab faib ua peb pawg, uas yog dig muag vias, faus vias thiab vias.

Qhov qhov muag tsis pom kev yog nyob rau sab saum toj thiab hauv qab ntawm lub rooj tsav xwm hauv Circuit Court, nrog rau qee qhov tob, thiab yog siv rau kev sib txuas ntawm lub voj voog saum npoo thiab sab hauv Circuit Court. Qhov tob ntawm lub qhov feem ntau tsis tshaj ib qho piv txwv (inch).

faus vias yog qhov sib txuas nyob rau hauv txheej sab hauv ntawm lub rooj tsav xwm hauv Circuit Court thiab tsis txuas mus rau saum npoo ntawm lub rooj tsavxwm. Qhov saum toj no ob hom ntawm qhov yog nyob rau hauv lub puab txheej ntawm lub rooj tsavxwm Circuit Court, thiab ua tiav los ntawm lub qhov txheej txheem ua ntej lamination.

Los ntawm qhov xa mus rau lub qhov uas dhau los ntawm tag nrho lub rooj tsav xwm hauv Circuit Court thiab tuaj yeem siv rau kev sib txuas sab hauv lossis ua qhov mounting qhov chaw rau cov khoom. Vim tias qhov dhau los ntawm qhov yooj yim dua rau kev paub hauv cov txheej txheem thiab tus nqi qis dua, nws yog siv rau hauv feem ntau cov ntawv pov thawj PCB.

2. Cov muaj pes tsawg leeg ntawm vias

Los ntawm qhov tsim ntawm qhov pom, lub viav vias yog tsim los ntawm ob ntu, ib qho yog qhov laum hauv nruab nrab, thiab lwm qhov yog qhov chaw ncoo nyob ib ncig ntawm lub qhov laum. Qhov loj ntawm ob ntu no txiav txim siab qhov loj ntawm cov viav vias. Nyob rau hauv high-ceev, high-density PCB tsim, designers yeej ib txwm xav kom lub vias kom me me li sai tau, thiaj li hais tias muaj ntau qhov chaw nyob rau ntawm lub rooj tsavxwm. Txawm li cas los xij, qhov txo qis hauv qhov loj kuj nce tus nqi, thiab qhov loj ntawm lub qhov ntawm lub qhov yog txwv los ntawm cov txheej txheem thev naus laus zis xws li drilling thiab electroplating: qhov me me, qhov ntev nws yuav siv sij hawm los xyaum, thiab qhov yooj yim dua nws yog deviate los ntawm lub qhov. qhov chaw nruab nrab; thiab Thaum qhov tob ntawm lub qhov siab tshaj 6 npaug ntawm txoj kab uas hla ntawm lub qhov drilled, tsis muaj kev lees paub tias lub qhov phab ntsa tuaj yeem ua tau zoo sib xws nrog tooj liab.
