FAQ

Qhov muag tsis pom kev: Thaum tsuas yog ib sab ntawm lub vias nyob rau hauv txheej txheej ntawm PCB, lawv hu ua dig muag vias.

faus vias: Thaum ob sab ntawm lub vias raug faus rau hauv txheej txheej ntawm PCB, lawv hu ua faus vias.

Ua ntej, peb tham txog laser laum qhov muag tsis pom ntawm qhov. PCB dig muag ntawm fabrication txheej txheem raws li hauv qab no:

1) ua kom tiav tag nrho cov txheej sab hauv ua ntej;

2) laminate ob txheej ntawm prepreg thiab tooj liab daim ntawv ntawm cov npaj tiav puab txheej ntawm PCB board;

3) laum qhov kev tswj qhov tob qhov muag tsis pom ntawm ntawm PCB los ntawm laser.

Thov nco ntsoov qhov tseeb yog qhov tseem ceeb heev rau qhov muag tsis pom ntawm hauv ncoo.

Raws li cov neeg kho tshuab laum qhov muag tsis pom ntawm qhov, peb siv 4-txheej PCBs nrog qhov muag tsis pom hauv txheej 1 mus rau txheej 2 piv txwv, cov txheej txheem raws li hauv qab no:

1) tsim cov khaubncaws sab nraud povtseg 1 thiab 2 raws li tus qauv 2-txheej PCB, yog li yuav muaj kev xyaum ntawm cov khaubncaws sab nraud povtseg 1 txog 2;

2) laminate ob core boards ua ke yog li peb tau txais 4-txheej PCB, thiab laum cov plating los ntawm qhov;

3) Thaum PCB tiav lawm, koj tau txais PTH los ntawm cov khaubncaws sab nraud povtseg 1 txog 4 thiab qhov muag tsis pom ntawm txheej 1 txog 2.

Cov txiaj ntsig ntawm kev siv qhov muag tsis pom thiab faus yog teev hauv qab no:

Txo qhov loj thiab qhov hnyav ntawm PCB

Txo cov txheej txheej

Txo cov nqi ntawm kev tsim khoom ntawm ntau hom PCBs txij li kev sib txuas ua haujlwm ntau dua

Txhim kho cov electromagnetic compatibility

Nce tus yam ntxwv ntawm cov khoom siv hluav taws xob

Ua kom tus qauv tsim ua haujlwm yooj yim dua thiab nrawm dua

Lub miniaturization ntawm lub diameters ntawm qhov muag tsis pom thiab faus vias qhov chaw siab dua ntawm PCB ntau lawm.

Cov engineers muaj kev paub dhau los xav tau los tsim qhov muag tsis pom thiab faus ntawm PCBs.

Nws yog qhov nyuaj dua los sib sau ua ke qhov muag tsis pom thiab faus ntawm PCBs vim lawv ib txwm muaj cov ntaub qhwv me me, xws li BGA pads.

Hauv laser laum qhov muag tsis pom vias board, qhov muag tsis pom kev ntawm qhov sib piv yog 1: 1.

faus vias hauv PCB yog ntawm qhov nruab nrab ntawm cov txheej sab hauv. Peb muab 6 txheej qhov muag tsis pom / faus ntawm lub rooj tsav xwm hauv Circuit Court piv txwv: qhov muag tsis pom kev tuaj yeem ntawm qhov ntawm txheej 2-3, 2-4, 2-5, 3-4, 3-5 thiab 4-5.

Qhov muag tsis pom ntawm thiab faus ntawm feem ntau siv HDI PCBs, lawv ib txwm muaj nyob rau hauv high tech high density printed circuit boards tib lub sij hawm. Tab sis lawv yog tag nrho ntau hom vias.
