Hauv kev tsim hluav taws xob niaj hnub no, PCB (Printed Circuit Board) yog ib qho tseem ceeb hauv kev tiv thaiv. Ntawm lawv, PCB drilling tshuab ua lub luag haujlwm tseem ceeb hauv kev tsim cov khoom siv hluav taws xob.
PCB drilling yog ib qho tseem ceeb ntawm kev tsim khoom siv hluav taws xob. Los ntawm kev drilling thiab ua tiav, cov pins ntawm ntau yam khoom siv txuas nrog lub voj voog ntawm lub rooj tsav xwm hauv Circuit Court kom ua tiav kev sib txuas ntawm lub voj voog. Hauv kev ua haujlwm drilling, muaj ob yam tseem ceeb cuam tshuam: qhov loj me ntawm qhov drilling thiab cov txheej txheem drilling.
Qhov loj drilling yog hais txog txoj kab uas hla ntawm lub borehole, feem ntau ntsuas hauv millimeters. Tej zaum yuav muaj ntau pua lossis ntau txhiab lub qhov laum ntawm lub rooj tsavxwm, thiab qhov loj ntawm txhua qhov kev xyaum yuav txawv. Cov khoom sib txawv lossis kev sib txuas yuav tsum tau drilling ntawm ntau qhov sib txawv kom tau raws li qhov xav tau ntawm ntau qhov xwm txheej.
Txoj kev drilling yog hais txog kev ua haujlwm tshwj xeeb rau kev drilling. Tam sim no, cov txheej txheem drilling tseem ceeb hauv kev ua lag luam suav nrog cov tshuab drilling, laser drilling, thiab electrolytic drilling.
Mechanical drilling yog qhov ntxov tshaj plaws thiab feem ntau txoj kev drilling. Nws siv cov tshuab drilling tshuab thiab cov cuab yeej ua teb los laum qhov hauv Circuit Court boards. Vim yog kev lag luam yooj yim thiab tus nqi qis ntawm cov tshuab drilling, nws yog dav siv hauv cov lag luam me thiab nruab nrab thiab cov khoom siv qis. Txawm li cas los xij, qhov tsis zoo ntawm cov neeg kho tshuab drilling yog qhov tseeb qhov drilling yog qhov tsawg, qhov drilling txoj kab uas hla yog qhov yooj yim rau deformation, thiab nws tsis haum rau cov khoom uas muaj qhov siab precision.
Laser drilling yog hom tshiab ntawm txoj kev drilling uas tau tsim nyob rau xyoo tas los no. Nws siv lub laser beam kom meej qhov chaw thiab xyaum qhov los ntawm laser ablation. Laser drilling muaj cov yam ntxwv ntawm kev ua haujlwm siab, kev kub ceev, thiab kev ruaj ntseg siab, tshwj xeeb tshaj yog tsim rau qhov zoo thiab qhov ntom ntom PCB drilling, thiab muaj qhov tshwj xeeb zoo rau cov khoom siv siab. Txawm li cas los xij, cov khoom siv laser drilling yog kim, nyuaj rau kev khiav lag luam, thiab laser ablation tuaj yeem tsim cov pa phem ntau, uas muaj qee yam cuam tshuam rau ib puag ncig thiab kev noj qab haus huv ntawm cov neeg ua haujlwm.
Electrolytic Drilling yog lwm txoj kev siv dav siv drilling. Nws siv lub hauv paus ntsiab lus ntawm electrolyte corrosion los laum qhov hauv electrolytic media. Electrolytic drilling muaj cov yam ntxwv ntawm kev ua haujlwm ceev ceev thiab siab aperture raug, uas yog tsim rau qee cov khoom uas yuav tsum tau nruj precision. Txawm li cas los xij, electrolytic drilling yuav tsum tau siv cov cuab yeej nyuaj thiab cov txheej txheem tshwj xeeb, thiab cov electrolyte tuaj yeem ua rau qee qhov ua paug ib puag ncig.
