Nyob rau hauv lub ntiaj teb ntawm electronics, luam tawm cov laug cam (PCBs) yog cov khoom siv tseem ceeb uas ua rau cov khoom siv hluav taws xob feem ntau. Cov txheej txheem kev tsim cov rooj zaum nyuaj no cuam tshuam nrog ntau cov kauj ruam, ib qho tseem ceeb tshaj plaws uas yog li drilling. Xaiv lub npe luam tawm cov board Laud me me yog qhov tseem ceeb rau kev ua kom ua tau zoo thiab ua kom zoo dua ntawm cov khoom kawg. Kab lus no yuav coj koj los ntawm cov ntsiab lus tseem ceeb los txiav txim siab thaum xaiv PCB laum me ntsis rau koj cov Cirtric Board qhov xav tau.
Cov kev txiav txim siab tseem ceeb rau kev xaiv
1. Laim loj me me: qhov loj ntawm laum me ntsis yog qhov tseem ceeb. Nws yuav tsum phim cov specifications ntawm cov khoom sib xyaw ua ke tau muab tso rau ntawm PCB. Cov qauv qhov ntau thiab tsawg ntawm 0.2 hli rau 3.2 mm, tab sis kev kho cov khoom siv tau rau hauv cov ntawv thov tshwj xeeb.
2. Cov khoom sib xyaw: sib txawv pcb cov ntaub ntawv yuav tsum muaj cov khoom sib txawv. Piv txwv li, iav reasfuled xws li fr-4 yuav xav tau lub carbide laum me ntsis, thaum cov ntaub ntawv softer tuaj yeem ua haujlwm nrog HSS laum me ntsis.
3. Drilling Ceev: Drilling ceev cuam tshuam rau qhov zoo ntawm lub qhov drilling. Kev nrawm nrawm yog siv tau ntau dua, tab sis kuj tseem yuav nce qhov kev pheej hmoo ntawm kev ua kom pcb. Nws yog qhov tseem ceeb kom pom qhov sib npaug uas haum koj cov kev xav tau kev xav tau tshwj xeeb.
4. Cua txias thiab lubrication: drilling generates cua sov, uas tuaj yeem ua puas lub laum me ntsis thiab PCB. Siv lub kaw lus txias lossis lubrication txias tuaj yeem pab tswj qhov kub siab thiab ntev ntev lub neej ntawm laum me ntsis.
5. Tus nqi vs. Zoo: Thaum nws yuav raug ntxias kom xaiv cov kev xaiv pheej yig tshaj, nqis peev hauv cov khoom zooPCB Board Laum Khoomtuaj yeem txuag koj nyiaj hauv lub sijhawm ntev. Kev xyaum laum zoo txo qhov kev pheej hmoo ntawm tawg thiab ntseeg tau cov cua huv, ua rau muaj tsawg dua qhov tsis xws luag nyob rau hauv cov khoom kawg.

Xaiv cov luam ntawv zoo tshaj plawsCircuit Court BoomNtsis yog ib qib tseem ceeb hauv pcb tsim qauv. Los ntawm kev nkag siab txog cov hom xyaum laum khoom muaj thiab xav txog yam xws li loj, cov khoom sib xyaw, koj tuaj yeem ua haujlwm nrawm thiab ua kom muaj txiaj ntsig zoo. Txawm hais tias koj yog tus hobbyist lossis tus kws tshaj lij hauv kev lag luam hluav taws xob, ua ib qho kev xaiv ntawm Circuit Court, ua ib qho kev xaiv ntawm Circuit Coal Laum cov khoom lag luam thiab kev ntseeg tau ntawm koj cov khoom siv hluav taws xob.
