PCB thaiv yog qhov txuas tseem ceeb hauv PCB tsim. Qee tus phooj ywg tsis paub ntau npaum li cas PCB thaiv dav dav feem ntau tau teeb tsa. Nov peb qhia ntau npaum li cas PCB thaiv dav dav feem ntau tau teeb tsa.

Kev dav dav PCB thaiv kab dav dav los txiav txim siab txog ob qhov teeb meem. Ib qho yog qhov loj ntawm qhov tam sim no, yog tias tam sim no dhau los ntawm cov lus loj, kab tsis tuaj yeem ua kom nyias nyias; Qhov thib ob yog txiav txim siab lub phaj tiag tiag ua lub peev xwm ntawm lub rooj tsav xwm lub Hoobkas yog tias tam sim no me me, tom qab ntawd kab tuaj yeem ua tau me ntsis, tab sis nyias dhau, qee lub rooj tsav xwm PCB pawg thawj coj yuav tsis tsim, lossis tsim tawm tab sis cov txiaj ntsig nce, yog li peb yuav tsum txiav txim siab pawg thawj coj saib teeb meem.

PCB thaiv kab dav dav feem ntau teeb tsa

Cov kab dav dav dav tau tswj rau 6/6mil, thiab xaiv qhov yog 12mil (0.3mm), uas tuaj yeem tsim los ntawm cov tuam txhab PCB feem ntau ntawm tus nqi qis.

Kab dav kab kab nrug deb tsawg kawg tswj kom 4/4mil, los ntawm qhov xaiv 8mil (0.2mm), ntau dua ib nrab ntawm cov tuam txhab PCB tuaj yeem tsim, tab sis tus nqi yuav kim dua li ntawm pem hauv ntej.

Txoj kab dav dav yam tsawg kawg nkaus yog tswj rau 3.5/3.5mil, thiab xaiv qhov yog 8mil (0.2mm). Tsawg PCB cov tuam txhab tuaj yeem tsim PCB, thiab tus nqi yuav kim dua me ntsis.

Qhov dav kab tsawg kawg yog tswj rau 2/2mil, thiab xaiv qhov yog 4mil (0.1mm). Ntau lub tuam txhab PCB tsis tuaj yeem tsim nws, thiab tus nqi zoo li no yog qhov siab tshaj.

Txoj kab dav tuaj yeem teeb tsa raws li PCB tsim kev ntom ntom. Yog tias qhov ntom me me, kab dav thiab kab sib nrug tuaj yeem teeb tsa kom loj dua. Yog tias qhov ntom ntom loj, kab dav thiab kab sib nrug tuaj yeem teeb tsa kom me dua:

1) 8/8mil, 12mil (0.3mm) rau qhov ntxeem tau.

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

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

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

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

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