1. Qhov tseem ceeb ntawm qhov tseeb drilling thiab qhov zoo ntawm phab ntsa hauv 4-txheej PCB pawg-up:

Drilling raug thiab qhov zoo ntawm phab ntsa yog qhov tseem ceeb uas cuam tshuam ncaj qha rau kev ua haujlwm ntawm 4-txheej PCB pawg. Tsis zoo drilling qhov tseeb tuaj yeem ua rau cov khoom tsis zoo, teeb meem impedance, thiab teeb meem kev ncaj ncees. Ib yam li ntawd, qhov tsis txaus ntawm phab ntsa zoo tuaj yeem cuam tshuam cov txiaj ntsig ntawm plated los ntawm qhov (PTH) kev sib txuas, ua rau muaj kev ntseeg siab thiab txo qis kev ua haujlwm ntawm hluav taws xob.

2. Xaiv cov cuab yeej drilling zoo thiab siv tshuab:

Txhawm rau kom ntseeg tau qhov tseeb ntawm qhov drilling, nqis peev hauv cov cuab yeej zoo drilling uas tso cai rau kev tswj xyuas qhov ceev ntawm qhov drilling, qhov tob, thiab kev sib dhos. Tsis siv neeg drilling tshuab nrog cov yam ntxwv siab heev xws li laser-pab drilling thiab computer-tswj precision yog pom zoo. Tsis tas li ntawd, xav txog laser-drilled microvias rau qib siab multilayer boards raws li lawv muab superior precision thiab kev ntseeg tau.

3. Qhov zoo tshaj plaws stacking tsim:

Kev tsim cov txheej txheem tsim nyog ua lub luag haujlwm tseem ceeb hauv kev ua tiav qhov raug drilling thiab qhov zoo ntawm phab ntsa. Thov xav txog cov lus qhia hauv qab no:
- Txo tus naj npawb ntawm cov teeb liab txheej kom txo tau qhov nyuaj drilling.
- Khaws cov tub ntxhais tuab tuab kom tiv thaiv qhov drilling qhov los ntawm tilting.
- Siv qhov sib npaug ntawm tooj liab kom tsis txhob khoov thiab warping thaum lub sij hawm drilling.
- Muab cov teeb liab ceev ceev thiab cov khoom rhiab nyob deb ntawm qhov chaw drilled kom txo qhov kev pheej hmoo ntawm hluav taws xob cuam tshuam.

4. Precision PCB manufacturing txheej txheem:

Capel muaj 15 xyoo ntawm kev paub thiab ua raws li cov txheej txheem tsim khoom nruj kom ntseeg tau tias qhov raug drilling thiab cov phab ntsa zoo hauv 4-txheej PCB pawg-ups. Nrog lub xeev-ntawm-the-art cov chaw thiab cov neeg ua haujlwm txawj, lawv siv cov thev naus laus zis xws li Laser Direct Imaging (LDI) thiab Kev Tshuaj Ntsuam Xyuas Kev Kho Hniav (AOI) kom meej meej thiab kev tshuaj xyuas zoo thaum lub sijhawm tsim khoom. Qhov kev txawj ntse no lav txhim khu kev qha, muaj zog PCBs rau cov neeg siv khoom.

5. Kev ntsuas kev tswj xyuas zoo:

Capel txoj kev cog lus rau kev tswj xyuas zoo yog tshwm sim hauv nws cov txheej txheem tshuaj xyuas nruj. Lawv siv cov kev sim siab tshaj plaws, suav nrog kev ntsuas hluav taws xob, kev ntsuas kev ntseeg tau thiab kev ntsuas kev laus thermal. Los ntawm kev saib xyuas lub sijhawm thiab ua raws li cov qauv zoo thoob ntiaj teb, Capel ua kom txhua tus PCB lawv tsim tau raws li cov neeg siv khoom xav tau.

6. Capel's PCB prototyping thiab kev pabcuam kev sib dhos:

Raws li ib tug-nres PCB cov kev daws teeb meem, Capel tsis tsuas yog tshwj xeeb hauv kev tsim 4-txheej PCB pawg-ups, tab sis kuj muab PCB prototyping sai thiab muaj txiaj ntsig SMT PCB cov kev pabcuam sib dhos. Txoj kev ua kom yooj yim no tshem tawm qhov xav tau rau ntau tus neeg muag khoom thiab ua kom muaj kev sib koom ua ke ntawm txhua theem ntawm PCB ntau lawm, yog li txuag lub sijhawm thiab txo cov nqi rau nws cov neeg siv khoom muaj txiaj ntsig.

Hauv kev xaus:

Thaum nws los txog rau kev ua tiav qhov tseeb drilling thiab qhov zoo ntawm phab ntsa hauv 4-txheej PCB stackup, ua haujlwm nrog cov chaw tsim khoom thiab txhim khu kev qha PCB zoo li Capel yog qhov tseem ceeb.Capel sawv tawm hauv kev lag luam nrog nws qhov tseem ceeb ntawm kev tswj kom zoo, kev siv thev naus laus zis thiab cov kev daws teeb meem zoo tshaj plaws PCB. Los ntawm kev saib xyuas qhov tseeb ntawm qhov drilling qhov thiab qhov zoo ntawm phab ntsa, koj tuaj yeem ua kom muaj kev ua tau zoo dua thiab ua haujlwm ntev ntawm koj cov khoom siv hluav taws xob.
