14 Txheej ENIG FR4 faus ntawm PCB
Hais txog qhov muag tsis pom faus ntawm PCB
Qhov muag tsis pom vias thiab faus vias yog ob txoj hauv kev los tsim kev sib txuas ntawm cov khaubncaws sab nraud povtseg ntawm lub rooj tsavxwm.Qhov dig muag vias ntawm lub rooj tsav xwm luam tawm yog tooj liab-plated vias uas tuaj yeem txuas rau txheej txheej los ntawm feem ntau ntawm cov txheej sab hauv.Lub burrow txuas ob lossis ntau txheej txheej sab hauv tab sis tsis nkag mus rau txheej txheej.Siv microblind vias los ua kom cov kab xa tawm ceev, txhim kho xov tooj cua zaus thiab electromagnetic cuam tshuam, thermal conduction, siv rau servers, xov tooj ntawm tes, digital koob yees duab.
Buried Vias PCB
Vias faus txuas ob lossis ntau txheej txheej sab hauv tab sis tsis nkag mus rau txheej txheej
Min qhov taub / mm | Min nplhaib / mm | ntawm-hauv-pad Diameter/mm | Qhov siab tshaj plaws / mm | Aspect Ratio | |
Blind Vias (conventional) | 0.1 | 0.1 | 0.3 | 0.4 | 1:10 |
Blind Vias (cov khoom tshwj xeeb) | 0.075 ib | 0.075 ib | 0.225 ib | 0.4 | 1:12 |
Blind Vias PCB
Qhov muag tsis pom Vias yog txuas ib txheej txheej mus rau yam tsawg kawg ib txheej sab hauv
| Min.Qhov taub / mm | Yam tsawg kawg nkaus lub nplhaib / mm | ntawm-hauv-pad Diameter/mm | Qhov siab tshaj plaws / mm | Aspect Ratio |
Blind Vias (mechanical drilling) | 0.1 | 0.1 | 0.3 | 0.4 | 1:10 |
Blind Vias(Laser Drilling) | 0.075 ib | 0.075 ib | 0.225 ib | 0.4 | 1:12 |
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.
