Qhov Deficiencies Ntawm Qhov Muag Tsis Pom Kev Txhaum Vias PCB

Qhov teeb meem tseem ceeb ntawm qhov muag tsis pom kev faus ntawm PCB yog tus nqi siab.Nyob rau hauv sib piv, faus qhov raug nqi tsawg dua qhov muag tsis pom qhov, tab sis kev siv ob hom ntawm qhov yuav ua rau kom tus nqi ntawm ib lub rooj tsavxwm.Tus nqi nce yog vim cov txheej txheem tsim khoom ntau dua ntawm qhov tsis pom kev faus qhov, uas yog, qhov nce hauv cov txheej txheem tsim khoom kuj ua rau kev nce hauv kev sim thiab tshuaj xyuas cov txheej txheem.

faus ntawm PCB

faus ntawm PCBs yog siv los txuas cov txheej sab hauv sib txawv, tab sis tsis muaj kev sib txuas nrog cov txheej txheej sab nraud.Ib qhov sib cais cov ntaub ntawv yuav tsum tau tsim rau txhua qib ntawm qhov faus.Qhov sib piv ntawm qhov tob rau qhov aperture (kev sib piv / thickness-inch ratio) yuav tsum tsawg dua los yog sib npaug rau 12.

Lub keyhole txiav txim siab qhov tob ntawm qhov keyhole, qhov siab tshaj plaws ntawm qhov sib txawv ntawm cov khaubncaws sab nraud povtseg. Feem ntau, qhov loj ntawm lub nplhaib puab lub nplhaib, qhov ruaj khov thiab txhim khu kev qha kev sib txuas.

Blind Buried Vias PCB

A: faus vias

B: Laminated faus ntawm (tsis pom zoo)

C: Hla faus ntawm

Qhov zoo ntawm Vias qhov muag tsis pom thiab faus Vias rau cov kws tshaj lij yog qhov nce ntawm cov khoom siv ntom ntom uas tsis muaj cov txheej txheem ntau ntxiv thiab qhov loj ntawm lub rooj tsav xwm Circuit Court.Rau cov khoom siv hluav taws xob nrog qhov chaw nqaim thiab kev tsim me me, kev tsim lub qhov muag tsis pom kev yog qhov kev xaiv zoo.Kev siv cov qhov no pab cov kws tsim hluav taws xob tsim hluav taws xob tsim lub qhov tsim nyog / ncoo piv kom tsis txhob muaj qhov sib piv ntau dhau.
