Sezvo kugadzirwa kwePCB kuri kufambira mberi kuine huwandu hwakawanda hwezvinhu, nzvimbo dzakatetepa dzemitsetse, kuwanda kwezvikamu uye mwero wemhando yemaburi, kuchera maburi kwave kuri imwe yenzira dzakakosha dzinokanganisa goho, kururama kwezvikamu uye mutengo wekugadzira. Mukuchera maburi ePCB nekukurumidza, maburi ekuchera maburi anodiwa kucheka jira remhangura, fiber yegirazi, masisitimu eresin uye zvinhu zvinozadza zviri kuwedzera kukura uku uchichengetedza mipendero yakapinza, kuburitsa machip akasimba uye mhando yemadziro emaburi yakafanana. Mishumo yeindasitiri yakaratidza kuti mukuchera maPCB ane huwandu hwakawanda hwezvinhu, kutadza kwekuboorera kwakabatana zvakanyanya nekunamatira kweresin, kupera kwemucheto nekukurumidza, kushanduka kwemaburi uye kutsiva maturusi kakawanda, kunyanya sezvo kumhanya kwekuboorera uye kuwanda kwezvikamu kuri kuramba kuchiwedzera.
Nekuda kwechikonzero ichi,Kuputira kwePCB micro-drillHaisisiri nzira iri nyore "inodzivirira kupera". Yava kuva mhinduro yeinjiniya yepamusoro inoda mashandiro akakwirira kubva kumidziyo yekuputira vacuum. Kuputira uku kunofanira kuwedzera kuomarara, kuderedza kukweshana, kudzvinyirira kunamira kwe resin yakavakwa, kuwedzera kuchengetedza mucheto uye kuchengetedza geometry yekutanga yemadrill ecarbide akakura. Izvi zvinoisa zvinodiwa zvitsva pakudzora chimiro chemafirimu, kugadzikana kweplasma, kudzvinyirira zvidimbu, kutonga tembiricha uye kugadzikana kwebatch.
Chinodiwa chekutanga kudzora machira akatetepa uye akafanana zvakanyanya. Machira madiki ePCB ane dhayamita diki kwazvo, mipendero yakapinza yekucheka uye flute geometries dzakaoma. Ukobvu hwakanyanya hwemachira hunogona kutenderedza mupendero wekucheka, kukanganisa kubviswa kwemachipisi kana kushandura nzvimbo yekucheka yakagadzirwa. Nokudaro, michina yekupenda inofanira kukwanisa kuisa mafirimu akakora, anoenderera mberi uye akafanana pa micron kana kunyange sub-micron scale, ukuwo ichivimbisa kufukidza kwakanaka pamupendero wekucheka, pamusoro peflute uye pamucheto wekuboorera. Kune machira akadai se ta-C, DLC, AlTiN, AlCrN, TiAlSiN kana multilayer hard coatings, michina inofanira kunyatso dzora mwero wekuisa, simba reion uye ukobvu hwefirimu kuti ienzanise kuoma, kunamira uye kupinza kwemupendero.
Chinodiwa chechipiri kugona kuisa zvinhu zvisina zvidimbu zvakawanda. Kuisa zvinhu mu cathodic arc yechinyakare kunoita kuti pave ne ionization rate yakawanda uye kunamira zvakasimba mufirimu, asi macroparticles anogona kuva chinhu chakakosha pakushandisa micro-tools. Kune ma PCB micro-drills, kunyangwe zvinhu zvidiki zviri pamucheto wepamusoro zvinogona kukonzera kushushikana kwenzvimbo, kubhoorwa kusina kugadzikana, kukwenya madziro emakomba kana kutadza kupfeka zvakanaka. Ndokusaka tekinoroji ye magnetic filtered arc, ma filtered cathodic vacuum arc systems uye optimized plasma filtering structures zvichiri kukosha. Magnetic filtration inogona kuderedza zvinhu zvikuru uye kugadzirisa kutsvedzerera kwe coating, iyo inonyanya kukosha kune DLC uye ta-C superhard coatings dzinoshandiswa pama micro-drills.
Chinodiwa chechitatu kunamatira kwakasimba pasina kukuvara kwekupisa. MaPCB micro-drills anowanzogadzirwa necarbide yakagadzirwa nesimende, uye mashandiro avo ekucheka anoenderana zvakanyanya ne geometry yekumucheto kwevhu chaiyo. Kana tembiricha yekuputira yakakwira zvakanyanya, substrate, chimiro chakasungirirwa kana kurongeka kwemucheto zvinogona kukanganiswa. Midziyo yemazuva ano yekuputira micro-drill inoda kuiswa kwakadzikama kwekushisa kwakaderera, kuchenesa kweion kwakanyanya kushanda uye dhizaini yakavimbika yeinterlayer. Matekinoroji akadai se ion source etching, bias-assisted deposition, Cr kana metal transition layers, uye graded interlayers anobatsira kuvandudza simba rekubatanidza pakati pe coating ne carbide substrate. Mamwe maitiro ekuputira ta-C akaseferwa anogona kuiswa pasi pe100 °C, zvichibatsira kuchengetedza geometry yema micro-sized carbide drills.
Chinodiwa chechina kuomarara kwakanyanya pamwe nekukweshana kushoma. Mukukweshana kwePCB, kukweshana kunofanira kuramba kukweshana kunobva mugirazi fiber, copper, resin uye ceramic fillers, ukuwo kuchideredza kupisa kwekukweshana uye kunamatira kwe resin. Firimu rakaoma asi rakaomarara rinogona kuwedzera kukweshana uye kukurumidzisa kuvharika kwema chips. Firimu rakatsetseka asi risina simba rekutakura mutoro rinogona kutadza nekukurumidza pasi pekukweshana nekumhanya kukuru. Naizvozvo, michina inofanirwa kukwanisa kugadzira kukweshana kune microstructure yakakora, huwandu hwakawanda hwe sp³ hwe ta-C kana DLC systems, coefficient yakaderera yekukweshana uye kukweshana kwakanaka. Tsvagiridzo pamafirimu edhaimani ePCB drills yakaratidza kuti zvivakwa zvedhaimani zve multilayer zvinogona kuvandudza hupenyu hwekukweshana uye hunhu hwemaburi pakugadzira zvinhu zvePCB zvine alumina ceramic fillers.
Chinodiwa chechishanu ndechekudzokororwa kwakanaka kwekuputira kuti pave nekuwanda. MaPCB micro-drills anowanzo putirwa muzvikamu zvakakura, uye chibooreso chega chega chinofanira kuchengetedza ukobvu hwefirimu hwakafanana, ruvara, kuomarara, kunamira uye kushanda kwetribological. Chero musiyano uripo munzvimbo yekuisa, huwandu hweplasma, mamiriro ekukukurwa kwemhepo, kugoverwa kwegasi kana voltage yekubiridzira zvinogona kutungamira mukusiyana kwekushanda pakati pemadrills. Naizvozvo, masisitimu ekuputira ePCB micro-drills anofanira kunge aine kushanda kwakasimba kwevacuum pumping, kudzora kuyerera kwehuwandu kwakarurama, kugoverwa kweplasma kwakafanana, kutenderera kwakavimbika/kuchinja uye kudzora resipi inodzokororwa. Kune vagadziri vezvishandiso, kukosha kwechokwadi kwemidziyo yekuputira hakusi kungowana mhedzisiro yakanaka yemuenzaniso chete, asiwo kuchengetedza kushanda kwakasimba mumabheti ekugadzira anoenderera mberi.
Chinodiwa chechitanhatu dhizaini yezvigadzirwa zvidiki zvine hungwaru uye zvekutakurwa. Zvichienzaniswa nemidziyo mikuru kana yekucheka yakajairika, maPCB micro-drills madiki zvikuru, haana kusimba uye anonzwa kurongeka kwekubatirira. Chigadzirwa ichi chinofanira kuve nechokwadi chekuti mutoro wacho wakakwira uku chichidzivirira mhedzisiro yekudzivirira, kuputira kusina kuenzana uye kukuvara kwemuchina. Kutenderera kwakawanda-axis, kurongeka kwekutakurisa, nzvimbo chaiyo yemidziyo uye kuratidzwa kweplasma kwakagadziridzwa zvinodiwa kuti pave nekuputira kwakafanana pamucheto wekuboorera nenzvimbo yeflute. Kune vagadziri vari kutsvaga kuburitswa kwakawanda, michina yekuputira inofanira kuyera kugona kwebatch nekufanana kwefirimu, pane kungowedzera huwandu hwekutakurisa.
Pamusoro pezvo, michina yePCB micro-drill coating inofanira kutsigira kubatanidzwa kwemapurogiramu akawanda. Sisitimu yemakwikwi yecoating haifanirwe kungogumira kune imwe mhando yefirimu. Inofanira kukwanisa kutsigira kuchenesa kweion, transition layer deposition, hard coating deposition, carbon-based coating deposition uye multilayer kana composite coating design. Semuenzaniso, ta-C, DLC, AlTiN, AlCrN, TiAlSiN, CrN uye hybrid hard coatings zvinogona kusarudzwa zvichienderana nezvinhu zvakasiyana zvePCB, kumhanya kwekuboora, dhayamita yemaburi uye zvinodiwa nevatengi. Kuchinjika kwemidziyo kunosarudza zvakananga kana mutengesi wecoating anogona kupindura kune zvinhu zvePCB zvinoshanduka nemamiriro ekuboora.
Kubva pamaonero ekugadzirwa kwePCB, chinangwa chikuru che micro-drill coating ndechekuderedza mutengo wega wega, kuwedzera nguva yekushandiswa kwezvishandiso, kuvandudza kunaka kwemadziro emaburi, kuderedza maburi nemakanganisika ekupinza zvipikiri, uye kudzikamisa mashandiro ekuboorera. Sezvo mabhodhi ePCB achinyanya kuoma uye zvinhu zvichinyanya kuoma kudhirowa, michina yekuboorera inofanira kuchinja kubva kumasystem ekare ekuboorera akaoma kuita mapuratifomu ekugadzira epamusoro-soro akanyatsojeka, ane zvidimbu zvishoma, anodziya zvishoma uye anogona kudzokororwa zvakanyanya.
Mune ramangwana, kukwikwidzana kwePCB micro-drill coating hakuzongotsamiri pakuoma kwecoating chete. Zvichatsamira pakugona kwakakwana kwemidziyo ye vacuum coating: kudzora plasma, kusefa kwezvikamu, kugadzikana kwekupisa, kugadzira adhesion, dhizaini ye fixture, kudzokorora maitiro uye kuvimbika kwekugadzirwa kwehuwandu. Kune vagadziri vemidziyo ye vacuum coating, iyi idambudziko rehunyanzvi uye mukana wemusika. Ani nani anogona kupa mhinduro dzakagadzikana, dzinoshanda zvakanyanya uye dzakanangana nekushandiswa kwePCB micro-drills achawana chinzvimbo chakasimba muchizvarwa chinotevera chekugadzira PCB yepamusoro.
