PCB thaiv yog ib feem tseem ceeb ntawm PCB tsim. Qee tus phooj ywg tsis paub ntau npaum li cas PCB xov kab kab dav dav feem ntau teeb tsa. Cia peb qhia ntau npaum li cas cov xov hlau thaiv kab dav dav feem ntau tau teeb tsa.

Feem ntau, muaj ob qhov teeb meem los txiav txim rau PCB thaiv kab dav. Thawj yog qhov loj ntawm qhov tam sim no. Yog tias qhov dej ntws tam sim no loj, kab tsis tuaj yeem ua kom nyias nyias; qhov thib ob yog txiav txim siab lub peev xwm tsim khoom tsim khoom ntawm pawg thawj coj saib lub Hoobkas. Yog tias tam sim no me me, cov kab tuaj yeem ua kom nyias nyias, tab sis yog tias nws nyias dhau, Qee lub rooj tsav xwm hauv PCB yuav tsis tuaj yeem tsim lawv, lossis lawv tuaj yeem tsim lawv tab sis cov txiaj ntsig tau nce, yog li pawg thawj coj saib xyuas haujlwm yuav tsum tau txiav txim siab .

Muaj pes tsawg tus PCB xov kab kab dav dav tau teeb tsa

Feem ntau, txoj kab dav thiab kab sib nrug tau tswj rau 6/6mil, thiab ntawm lub qhov yog 12mil (0.3mm). Cov tuam txhab PCB feem ntau tuaj yeem tsim nws, thiab tus nqi tsim khoom qis.

Yam tsawg kawg kab dav thiab kab sib nrug yog tswj rau 4/4mil, thiab ntawm lub qhov yog 8mil (0.2mm). Ntau tshaj li ib nrab ntawm cov tuam txhab PCB tuaj yeem tsim nws, tab sis tus nqi yuav kim me ntsis dua li yav dhau los.

Yam tsawg kawg kab dav thiab kab sib nrug yog tswj rau 3.5/3.5mil, thiab ntawm lub qhov yog 8mil (0.2mm). Muaj tsawg dua PCB cov tuam txhab tsim khoom tuaj yeem tsim, thiab tus nqi yuav kim dua me ntsis.

Yam tsawg kawg kab dav thiab kab sib nrug yog tswj rau 2/2mil, thiab ntawm lub qhov yog 4mil (0.1mm). Ntau lub tuam txhab pcb tsis tuaj yeem tsim nws. Hom nqi no yog qhov siab tshaj.

Yog tias txoj kab dav tau teeb tsa raws li qhov ntom ntom ntawm PCB tsim, qhov ntom tau me dua, thiab kab dav thiab kab sib nrug tuaj yeem teeb tsa kom loj dua, thiab qhov ntom tau tuaj yeem teeb tsa kom me dua:

1) 8/8mil, 12mil (0.3mm) rau ntawm qhov

2) 6/6mil, 12mil (0.3mm) rau ntawm qhov

3) 4/4mil, 8mil (0.2mm) rau ntawm qhov

4) 3.5/3.5mil, 8mil (0.2mm) rau ntawm qhov

5) 3.5/3.5mil, 4mil rau ntawm qhov (0.1mm, laser drilling).

6) 2/2mil, 4mil rau ntawm qhov (0.1mm, laser drilling).
