Thaum tsim qauv thiab tsim khoom lag luam luam tawm cov khoom siv hluav taws xob (PCBs), precision yog qhov tseem ceeb. Ib qho ntawm cov tseem ceeb tshaj plaws hauv pcb tsim cov txheej txheem yog lub laum me ntsis siv los tho qhov rau cov khoom siv thiab kab. Hauv phau ntawv qhia no, peb yuav tshawb ntau yam ntawmPC Laum Laum Khoom, lawv cov kev siv, thiab yuav ua li cas xaiv cov laum txoj cai rau koj qhov project.
Kawm txog PC Pawg Tub Looj
PCB laum me ntsis yog ib qho cuab yeej tsim tshwj xeeb rau cov qhov drilling qhov hauv PCBs. Cov kev xyaum laum yog tsim los tuav cov cim tshwj xeeb thiab thicknesses ntawm PCBS, uas feem ntau suav nrog fiberglass, epoxy, thiab lwm yam khoom siv. Txoj cai laum me ntsis tuaj yeem cuam tshuam qhov zoo ntawm koj lub PCB, cuam tshuam rau txhua yam los ntawm kev ncaj ncees ntawm koj cov kev ua tau zoo ntawm koj cov khoom siv hluav taws xob ntawm koj cov khoom siv hluav taws xob.
Cov Hom Kev Luam Tawm Circuit Coud Laum Yeej
1. Twist Laum me ntsis: Qhov no yog hom laum feem ntau siv rau PCBs. Lawv muaj cov zeem muag kauv tsim uas pab tshem tawm cov khib nyiab thaum drilling. Twist laum cov khoom sib tw yog ntau yam thiab tuaj yeem siv rau ntau qhov seem thiab siv tau xaiv nrog cov kws tshaj lij thiab cov tub txawg zoo tib yam.
2. Micro Drills: rau cov ntawv thov uas yuav tsum muaj qhov tsawg heev, micro hnyiab yog qhov tseem ceeb. 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. Txawm li cas los xij, lawv xav tau ceev faj tuav thiab kho cov kev siv drilling kom tsis txhob tawg.
3. Carbide Laum Cov Khoom Siv: Ua los ntawm tungsten carbide, cov laum no yog lub npe paub rau lawv cov kev ruaj khov thiab muaj peev xwm nyob ntse ntev li cas rau lub sijhawm ntev. Lawv tau tshwj xeeb rau kev khiav tawm ntawm cov ntaub ntawv nyuaj thiab feem ntau siv hauv kev tsim qauv PCb kev ib puag ncig.
4. Pob zeb diam iab coated tho: Rau qhov kawg qhov tseeb thiab thiav, pob zeb diamond coall bits yog qhov kev xaiv zoo. Pob zeb diamond txheej ua rau drilling smoother thiab txo qhov kev pheej hmoo ntawm chipping los yog tawg ntawm cov pcb cov khoom siv. Cov kev xyaum laum feem ntau kim dua, tab sis rau cov phiaj xwm zoo, lawv muaj nqis rau kev nqis peev.
Xaiv txoj cai laum me ntsis
Thaum xaiv cov PC ncaj PC laum me ntsis rau koj qhov project, xav txog cov hauv qab no yam:
- Cov khoom siv: cov khoom siv uas siv rau PCB yuav cuam tshuam qhov kev xaiv ntawm laum me ntsis. Rau tus qauv FR-4 Circuit Court, ib qho twist laum lossis carbide laum me ntsis feem ntau yog qhov txaus. Yog xav tau ntau cov ntaub ntawv tshwj xeeb, xws li ceramic lossis hlau-core pcbs, lub pob zeb diamond-coated tho me ntsis yuav tsum tau.
- Qhov luaj li cas: Txheeb xyuas qhov loj ntawm lub qhov uas yuav tsum tau ua haujlwm. Yog tias koj tus qauv muaj muaj ob qho qauv thiab micro qhov, koj yuav xav tau nqis peev pab rau twist thiab micro tho kev ua haujlwm.
- Drilling txheej txheem: Drilling txoj kev kuj cuam tshuam laum kev xaiv xyaum. Yog tias koj siv lub tshuab cnc, nco ntsoov lub laum me me yog sib xws nrog koj cov cuab yeej siv. Kev tuav ntaub pua chaw yuav xav tau kev txiav txim siab sib txawv, xws li lub zog muaj zog los tiv thaiv lub siab.
- Pob nyiaj: Thaum nws tau sim xaiv Laum tseem ceeb tshaj plaws, nqis peev hauv kev ua haujlwm siab yuav txuag koj lub sijhawm thiab nyiaj hauv lub sijhawm ntev. Qhov tsis zoo tho kev tuaj yeem ua rau Circuit Court kev puas tsuaj thiab tus nqi yuam kev.
Hauv kev xaus
Nyob hauv lub ntiaj teb ntawm PCB tsim thiab tsim khoom, cov cuab yeej zoo tuaj yeem ua txhua qhov sib txawv. Los ntawm kev nkag siab ntau hom kev ntsuas tho kev thiab lawv cov ntawv thov, koj tuaj yeem xaiv qhov kev xaiv zoo tshaj plaws rau koj qhov project. Txawm hais tias koj yog ib tug hobbyist lossis tus kws tshaj lij, nqis peev rau hauv kev tho kev zoo yuav ua kom koj lub pcbs yog tsim nrog qhov tseeb thiab kev ntseeg tau. Zoo siab Drilling!
