Hauv kev lag luam hluav taws xob, kev tsim khoom raug ntawm cov ntawv luam tawm Circuit Board (PCBS) ncaj qha cuam tshuam rau kev ua tau zoo thiab cov khoom siv hluav taws xob zoo. Raws li cov cuab yeej tseem ceeb hauv cov txheej txheem drilling, kev ua haujlwm ruaj khov thiab ua tiav ntawm PCB cov cuab yeej drilling yog qhov tseem ceeb heev. Ntawm lawv, ib qho tseem ceeb uas feem ntau tsis saib xyuas tab sis tseem ceeb heev - lub hauv paus granite - yog ntsiag to txiav txim siab seb lub peev xwm ntawm cov cuab yeej tuaj yeem ua kom tiav.
Cov yam ntxwv zoo ntawm granite hauv paus
Zoo stability, resistant rau kev vibration cuam tshuam
Thaum lub sijhawm PCB drilling txheej txheem, lub laum me ntsis tig ntawm kev kub ceev los txiav lub rooj tsavxwm, tsim kom muaj kev vibrations tas mus li thiab nyuaj. Lub hauv paus granite, nrog nws cov qauv ntom ntom thiab cov qauv tsim los ntawm cov txheej txheem geological ntau pua lab xyoo, muaj kev ua tau zoo heev seismic. High-zoo granite sawv cev los ntawm "Jinan Green" yog ib qho nyuaj hauv kev ntxhib los mos thiab tuaj yeem nqus tau zoo thiab cuam tshuam lub zog vibration tsim los ntawm kev ua haujlwm ntawm cov khoom siv, ua kom muaj kev ruaj ntseg ntawm cov khoom siv drilling thaum lub sijhawm ua haujlwm. Piv nrog rau lwm cov khoom siv hauv paus, granite tuaj yeem txo qhov cuam tshuam ntawm kev vibration ntawm qhov chaw qhov tseeb ntawm lub laum me ntsis, ua rau txoj haujlwm raug ntawm qhov drilling qhov siab dua thiab qhov sib txawv tswj tau nyob rau hauv ib qho me me, ua tau raws li qhov kev xav tau ntawm qhov drilling siab ntawm micro-qhov thiab qhov me me diameters rau high-density PCB boards.
High hardness thiab hnav tsis kam ua kom muaj qhov tseeb ntev
Kev ua haujlwm tsis tu ncua ua rau muaj kev sib tw zoo rau kev hnav tsis kam ntawm lub hauv paus nto. Lub Mohs hardness ntawm granite tuaj yeem ncav cuag 6 mus rau 7, deb tshaj li ntawm cov hlau thiab feem ntau engineering plastics. Cov yam ntxwv siab hardness no ua rau lub hauv paus granite kom zoo flatness thiab smoothness ntawm nws nto txawm tias thaum nws raug rau qhov cuam tshuam quab yuam thiab kev sib txhuam ntawm lub laum me ntsis ntev. Txawm tias tom qab ib tug loj tus naj npawb ntawm drilling dej num, lub degree ntawm hnav yog negligible, yog li ua kom lub sij hawm ntev kev ruaj ntseg ntawm cov cuab yeej drilling thiab qhov zoo sib xws drilling raug. Qhov no yog qhov tseem ceeb heev rau cov lag luam loj hauv PCB. Nws tuaj yeem txo cov khoom siv downtime thiab txij nkawm lub sij hawm tshwm sim los ntawm lub hauv paus hnav, txhim kho kev tsim khoom thiab txo tus nqi tag nrho.
Tsawg thermal expansion thiab contraction, adaptable rau kub hloov
Hauv PCB raug Rhiav, qhov kub thiab txias hloov pauv vim yog yam xws li lub caij nyoog thiab cov khoom siv cua sov dissipation. Lub hauv paus ua los ntawm cov ntaub ntawv sib txawv muaj qhov pom tseeb thermal expansion thiab contraction phenomena, uas yuav ua rau cov kev hloov nyob rau hauv tus txheeb ze txoj hauj lwm ntawm cov khoom siv thiab yog li cuam tshuam rau qhov drilling qhov tseeb. Granite muaj qhov coefficient tsawg heev ntawm thermal expansion. Piv txwv li, linear expansion coefficient ntawm ntau granite yog kwv yees li 4.6 × 10⁻⁶ / ℃. Thaum qhov kub thiab txias hloov, qhov luaj li cas ntawm lub hauv paus granite tseem yuav luag tas li, muab lub hauv paus ruaj khov thiab txhim khu kev qha rau cov khoom siv drilling. Txawm hais tias nyob rau lub caij ntuj sov los yog lub caij ntuj no txias, cov cuab yeej muaj peev xwm tswj tau lub xeev siab precision drilling, kom ntseeg tau qhov sib xws ntawm drilling zoo rau cov khoom sib txawv ntawm cov khoom PCB.
Kho cov txheej txheem ntawm PCB drilling khoom
Precise installation thiab positioning nteg lub hauv paus rau qhov raug
Thaum lub sij hawm ua cov granite hauv paus, los ntawm cov txheej txheem pob zeb diamond txiav thiab sib tsoo, tsis tshua muaj siab flatness thiab qhov tseeb qhov tseeb tuaj yeem ua tiav. Piv txwv li, lub flatness kam rau ua ntawm high-precision granite bases nyob rau hauv ib tug ntau yam ntawm 1m × 1m tuaj yeem tswj tsis pub ntau tshaj 4μm. Qhov no ua rau cov cuab yeej drilling tau muab ntsia tau sai thiab raug raws li lub dav hlau meej thiab qhov chaw ntawm lub hauv paus, nrog rau qhov sib txawv me me ntawm txhua qhov sib txawv. Kev txhim kho thiab qhov chaw muab kev lees paub rau qhov tseeb txav ntawm lub laum me ntsis thaum lub sijhawm ua haujlwm tom ntej ntawm cov khoom siv, txhim kho qhov tseeb ntawm qhov drilling thiab txo cov teeb meem zoo xws li qhov sib txawv ntawm qhov sib txawv thiab qhov tsis sib xws ntawm lub qhov taub uas tshwm sim los ntawm cov khoom siv tsis raug.
Txhim kho cov txheej txheem rigidity thiab txhim kho kev ua haujlwm ruaj khov
Thaum PCB drilling cov cuab yeej ua haujlwm, ntxiv rau nws tus kheej kev co, nws kuj tseem tuaj yeem cuam tshuam los ntawm kev thauj mus los sab nraud, cov chaw ua haujlwm tsis sib xws thiab lwm yam. Lub hauv paus granite muaj qhov ntom ntom thiab muaj zog rigidity. Tom qab ua tib zoo ua ke nrog cov qauv tseem ceeb ntawm cov cuab yeej, nws tuaj yeem txhim kho cov txheej txheem rigidity ntawm tag nrho cov khoom siv. Thaum cov cuab yeej raug cuam tshuam rau sab nraud quab yuam los yog kev co, lub hauv paus granite tuaj yeem sib npaug ntawm qhov cuam tshuam nrog nws tus kheej muaj zog rigidity, tiv thaiv cov khoom tseem ceeb ntawm kev txav los yog deforming vim lub zog tsis sib xws, thiab ua kom ruaj khov ntawm cov khoom siv hauv kev ua haujlwm nyuaj. Lub xeev kev ua haujlwm ruaj khov pab txhawb nqa lub neej kev pabcuam ntawm cov khoom siv thiab muab qhov chaw ua haujlwm ruaj khov thiab txhim khu kev qha rau cov khoom zoo drilling tib lub sijhawm.
Qhov tseeb ntau lawm daim ntawv thov nyhuv
PCB ntau lawm rau cov khoom siv hluav taws xob
Hauv kev tsim khoom ntawm PCBS rau cov neeg siv khoom siv hluav taws xob xws li cov xov tooj ntse thiab cov ntsiav tshuaj computer, qhov yuav tsum tau ua kom raug drilling yog qhov siab heev. Tom qab lub tuam txhab tsim hluav taws xob paub zoo tau qhia PCB cov cuab yeej drilling nruab nrog granite hauv paus, cov khoom lag luam tawm los ntawm qhov qub 80% mus rau ntau dua 90%. Cov teeb meem xws li cov kab tsis zoo sib txuas thiab luv luv Circuit Court tshwm sim los ntawm qhov tsis txaus drilling raug raug txo kom tsawg. Lub caij no, vim lub hauv paus granite txo cov zaus ntawm kev saib xyuas cov cuab yeej, lub peev xwm tsim tawm txhua hli ntawm lub tuam txhab no tau nce 20%, txo qis cov nqi tsim khoom ib chav tsev thiab yeej tus nqi thiab cov txiaj ntsig zoo hauv kev sib tw ua lag luam hnyav.
Kev tsim khoom ntawm industrial tswj board PCBS
Qhov chaw ua haujlwm ntawm kev tswj hwm kev lag luam yog qhov nyuaj, thiab kev cia siab rau PCBS yog nruj. Ib lub tuam txhab tshwj xeeb hauv kev tsim cov kev tswj hwm kev lag luam tau pom qhov nce ntxiv ntawm nws cov PCB boards hauv kev sim ib puag ncig hnyav xws li kub thiab av noo siab tom qab siv cov khoom siv drilling nrog granite hauv paus. Kev txhim kho kev ua haujlwm ruaj khov ntawm cov cuab yeej ua rau lub drilling zoo txhim khu kev qha, muab cov khoom ruaj khov rau kev ua haujlwm ruaj khov rau lub sijhawm ntev ntawm kev tswj xyuas kev lag luam. Nrog cov khoom lag luam zoo, lub lag luam tau ua tiav qhib ntau lub lag luam high-end cov neeg siv khoom lag luam, thiab nws cov lag luam nplai tau txuas ntxiv nthuav dav.
Granite bases, nrog rau lawv zoo heev stability, siab hardness thiab hnav tsis kam, nrog rau tsawg thermal expansion thiab contraction, ua lub luag hauj lwm irreplaceable nyob rau hauv kev txhim kho lub peev xwm ntawm PCB drilling khoom. Los ntawm kev txhim kho thiab qhov chaw kom txhim kho cov txheej txheem rigidity ntawm cov cuab yeej, thiab rau nws cov kev ua tau zoo nyob rau hauv ntau qhov tseeb ntau lawm scenarios, tag nrho cov tau pom tag nrho nws cov nqi tseem ceeb hauv kev txhim kho qhov drilling raug thiab ntau lawm efficiency ntawm PCBS. Nyob rau hauv txoj kev mus nrhiav kom tau ntau dua precision thiab efficiency nyob rau hauv PCB manufacturing, lub granite puag yog undoubtedly tus yuam sij rau xauv lub siab tshaj plaws peev xwm ntawm PCB drilling cov cuab yeej, thiab nws tsim nyog lub siab thiab dav daim ntawv thov ntawm ib tug loj tus naj npawb ntawm electronics manufacturing tuam txhab.
