Nyob rau hauv lub ntiaj teb ntawm electronics, luam tawm cov boardcuit Coffic boards (PCBs) yog tus caj qaum ntawm yuav luag txhua lub cuab yeej peb siv hnub no. Los ntawm cov khoom siv hauv tsev, PCBs yog qhov tseem ceeb rau kev sib txuas cov hluav taws xob sib xyaw. Ib qho tseem ceeb tshaj plaws ntawm PCB kev tsim yog yog qhov kev siv drilling, uas yog qhov twgPrint Circuit Coud Block BitsLos rau hauv kev ua si. Hauv cov blog no, peb yuav tshawb txog qhov sib txawv ntawm cov laum cov khoom siv tau siv rau PCBs, lawv cov lus qhia tshwj xeeb, thiab cov lus qhia rau xaiv cov cuab yeej zoo rau koj qhov project.
Subsun PCB Laum Khoom
Cov ntawv luam tawm cov khoom lag luam laum cov khoom lag luam yog cov cuab yeej tshwj xeeb siv los tho qhov hauv PCBs los tso cov khoom siv hluav taws xob. Cov khoom laum no los rau ntau qhov ntau thiab tsawg thiab cov ntaub ntawv, txhua tus txiav rau ib daim ntawv thov. Qhov raug thiab zoo ntawm laum me ntsis cuam tshuam rau tag nrho cov kev ua tau zoo thiab kev ntseeg tau ntawm PCB.
PCB Laum Taw Hom
1. Twist Laum Sij Hawm:Qhov no yog hom laum feem ntau siv rau PCBs. Lawv muaj ib tug kauv tsim uas pab tshem tawm cov khib nyiab thaum drilling. Twist laum cov khoom lag luam tuaj hauv ntau qhov diameters rau txawv qhov chaw.
2. Micro Tho Bits:Micro tho cov khoom me yog qhov tseem ceeb rau cov ntawv thov uas yuav tsum muaj qhov tsawg. Cov khoom laum no tuaj yeem tho qhov me me li 0.1 mm, ua rau lawv zoo tagnrho rau cov nyiaj siab high-density pcbs uas muaj qhov chaw tsawg.
3. Carbide Laum Cov Khaub Ncaws:Ua los ntawm tungsten carbide, cov laum cov raj yog paub rau lawv cov durability thiab muaj peev xwm nyob twj ywm ntev. Lawv yog qhov tshwj xeeb rau kev khiav tawm ntawm cov ntaub ntawv nyuaj, ua rau lawv xaiv cov tshuaj zoo rau cov PCB zoo.
4. Pob zeb diamond coated tho steard:Rau qhov kawg ntawm precision thiab ntev, pob zeb diamond coated tho kev yog tus qauv kub. Lub pob zeb diamond txheej txo kev sib txhuam thiab ua kom sov kom ua kom huv thiab siv lub neej ntev dua. Cov ntawv laum no feem ntau siv nyob rau hauv cov ntawv thov siab qhov twg yog qhov tseeb yog qhov tseem ceeb.
Cov ntsiab lus tseem ceeb los xav txog
Thaum xaiv lub laum me ntsis rau luam tawm cov laug cam lub rooj zaum, muaj ob peb qhov tshwj xeeb koj yuav tsum xav txog:
- Lub taub:Qhov luaj li cas ntawm laum me ntsis yog qhov tseem ceeb kom ntseeg tau lub qhov sib raws cov qauv tsim qauv ntawm PCB. Cov diam diameters ntau los ntawm 0.2 hli rau 3.2 hli.
- Ntev:Qhov ntev ntawm lub laum me ntsis yuav tsum phim cov tuab ntawm tus PCB. Cov laug multilayer kuj yuav xav tau laum ntev dua.
- Lub ces kaum ntse:Cov ces kaum ntse cuam tshuam cuam tshuam thiab qhov zoo. Txheem cov ces kaum ntse yog ib txwm 118 degrees, tab sis cov ces kaum, tsuas yog siv rau cov ntawv thov.
- Cov khoom siv:Cov khoom siv ntawm cov laum kev cuam tshuam nws cov kev ua tau zoo thiab kav lub neej. Carbide thiab pob zeb diamond-coated laum cov khoom lag luam yog qhov kev nyiam rau lawv cov kav ntev.
Cov lus qhia rau xaiv txoj cai laum me ntsis
1. Txheeb xyuas koj cov phiaj xwm koj yuav tsum:Ua ntej yuav cov laum me ntsis, ntsuas qhov tshwj xeeb ntawm koj tus PCB tsim. Xav txog qhov loj me ntawm lub qhov, tus naj npawb ntawm txheej, thiab cov ntaub ntawv siv.
2. Zoo tshaj tus nqi:Thaum nws yuav raug ntxias kom xaiv rau qhov pheej yig dua, nqis peev hauv kev xyaum pheej yig tuaj yeem txuag koj lub sijhawm thiab nyiaj hauv lub sijhawm ntev. Cov kev ntsuas laum laum txo cov kev pheej hmoo ntawm cov tawg thiab ua kom muaj qhov ua kom huv.
3. Kuaj ntau hom:Yog tias koj tsis paub meej tias laum me ntsis yog qhov zoo tshaj rau koj qhov project, txiav txim siab kuaj ob peb hom laum. Qhov no yuav pab koj txiav txim seb qhov xyaum me me yog qhov zoo tshaj rau koj daim ntawv thov tshwj xeeb.
4. Tswj koj cov cuab yeej:Kev tu xyuas kom zoo ntawm koj lub qhov tho yog qhov tseem ceeb rau txuas lawv lub neej. Huv thiab soj ntsuam lub laum cov khoom tsis tu ncua hnav thiab hloov cov khoom lag luam raws li xav tau los tswj kev ua yeeb yam zoo.
Hauv kev xaus
Cov ntawv luam tawm cov board laum cov khoom yog qhov tseem ceeb ntawm pcb tsim thiab ua si lub luag haujlwm tseem ceeb hauv kev ua kom meej meej thiab ntseeg tau. Los ntawm kev nkag siab txog cov kev sib txawv ntawm lub laum khoom muaj thiab xaiv cov lus qhia rau cov ntsiab lus tseem ceeb, koj tuaj yeem sau cov kev txiav txim siab paub tias yuav ua kom zoo ntawm koj cov phiaj xwm hluav taws xob. Txawm hais tias koj yog ib tug hobbyist lossis tus kws tshaj lij kev lag luam, nqis peev nyob rau hauv cov cuab yeej yog qhov kawg yuav ua rau muaj txiaj ntsig zoo thiab ua haujlwm tau zoo dua.
