Pamene kupanga ma PCB kukupita patsogolo kwambiri, mtunda wocheperako wa mizere, kuchuluka kwa zigawo ndi miyezo yofunikira kwambiri ya mabowo, kuboola kwaching'ono kwakhala njira imodzi yofunika kwambiri yokhudza kukolola, kulondola kwa miyeso ndi mtengo wopanga. Mu kuboola kwa PCB mwachangu kwambiri, kuboola kwaching'ono kumafunika kudula zojambula zamkuwa, ulusi wagalasi, makina a resin ndi zinthu zodzaza zomwe zimakhala zovuta kwambiri pamene zikusunga m'mbali zakuthwa, kuchotsa ma chip okhazikika komanso khalidwe lokhazikika la makoma a mabowo. Malipoti amakampani awonetsa kuti popanga ma PCB okhala ndi kuchuluka kwakukulu, kulephera kuboola kumalumikizidwa kwambiri ndi kumatirira kwa resin, kuwonongeka kwa m'mphepete mwachangu, kusintha kwa mabowo ndi kusintha zida pafupipafupi, makamaka pamene liwiro la kuboola ndi kuchuluka kwa zigawo zikupitirira kuwonjezeka.
Pachifukwa ichi,Chophimba cha PCB cha micro-bowoleSi njira yophweka "yosawonongeka ndi zinthu zosafunika". Ikukhala njira yolondola yopangira pamwamba yomwe imafuna magwiridwe antchito apamwamba kwambiri kuchokera ku zida zophikira vacuum. Chophikiracho chiyenera kukonza kuuma, kuchepetsa kukangana, kuletsa kumatirira kwa resin komwe kumamangidwa, kuwonjezera kusunga m'mphepete ndikusunga mawonekedwe oyambira a zobowola zazing'ono za carbide. Izi zikuyika zofunikira zatsopano pakuwongolera kapangidwe ka filimu, kukhazikika kwa plasma, kuletsa tinthu tating'onoting'ono, kuyang'anira kutentha ndi kusinthasintha kwa batch.
Chofunika choyamba ndikuwongolera chophimba choonda kwambiri komanso chofanana kwambiri. Ma PCB micro-drill ali ndi mainchesi ang'onoang'ono kwambiri, m'mphepete mwa kudula kowala komanso mawonekedwe ovuta a flute. Kukhuthala kwakukulu kwa chophimba kumatha kuzungulira m'mphepete mwa kudula, kukhudza kuchotsa chip kapena kusintha malo odulira omwe adapangidwa. Chifukwa chake, zida zophikira ziyenera kukhala zokhoza kuyika mafilimu okhuthala, opitilira komanso ofanana pa micron kapena sub-micron scale, pomwe zikuwonetsetsa kuti zili bwino pamphepete mwa kudula, pamwamba pa flute ndi nsonga ya kubowola. Pazophimba monga ta-C, DLC, AlTiN, AlCrN, TiAlSiN kapena multilayer hard coatings, zida ziyenera kuwongolera bwino kuchuluka kwa malo oikidwa, mphamvu ya ion ndi makulidwe a filimu kuti zigwirizane ndi kuuma, kumamatira ndi kuthwa kwa m'mphepete.
Chofunika chachiwiri ndi kuthekera koyika tinthu tating'onoting'ono tochepa. Kuyika kwa cathodic arc kwachikhalidwe kumapereka mphamvu yayikulu ya ionization komanso kumamatira mwamphamvu pa filimu, koma macroparticles amatha kukhala gwero lofunikira la zinyalala zazing'ono. Pa ma PCB micro-drills, ngakhale tinthu tating'onoting'ono tomwe tili m'mphepete mwake tingayambitse kupsinjika kwapafupi, kuboola kosakhazikika, kukanda makoma a mabowo kapena kulephera kwa kupaka msanga. Ichi ndichifukwa chake ukadaulo wa maginito wosefedwa wa arc, makina osefedwa a cathodic vacuum arc ndi mapangidwe okonzedwa bwino a plasma ndizofunikira kwambiri. Kusefa kwa maginito kumatha kuchepetsa tinthu tating'onoting'ono tating'onoting'ono ndikuwonjezera kusalala kwa kupaka, komwe ndikofunikira kwambiri pa DLC ndi ta-C superhard coating zomwe zimagwiritsidwa ntchito pa ma micro-drills.
Chofunikira chachitatu ndi kumatirira mwamphamvu popanda kuwonongeka kwa kutentha. Ma PCB micro-drill nthawi zambiri amapangidwa ndi carbide yopangidwa ndi simenti, ndipo magwiridwe antchito awo odulira amadalira kwambiri mawonekedwe a m'mphepete mwa nthaka. Ngati kutentha kwa chophimba kuli kokwera kwambiri, substrate, kapangidwe ka brazed kapena kulondola kwa m'mphepete kungakhudzidwe. Chifukwa chake, zida zamakono zomatira ma micro-drill zimafunikira malo okhazikika otentha, kuyeretsa ma ion ogwira ntchito bwino komanso kapangidwe kodalirika ka interlayer. Maukadaulo monga ion source etching, bias-assisted deposition, Cr kapena metal transition layers, ndi interlayer zoyesedwa zimathandiza kukonza mphamvu yolumikizirana pakati pa chophimba ndi carbide substrate. Njira zina zomatira ta-C zosefedwa zimatha kuyikidwa pansi pa 100 °C, zomwe zimathandiza kusunga mawonekedwe a ma micro-sized carbide drills.
Chofunika chachinayi ndi kuuma kwambiri pamodzi ndi kukangana kochepa. Mu kuboola PCB, chophimbacho chiyenera kukana kuwonongeka kochokera ku ulusi wagalasi, mkuwa, utomoni ndi zodzaza za ceramic, komanso kuchepetsa kutentha kokangana ndi kumamatira kwa utomoni. Filimu yolimba koma yolimba ingawonjezere kukana kudula ndikufulumizitsa kutsekeka kwa chip. Filimu yosalala koma yopanda mphamvu yonyamula katundu ingalephereke mwachangu poboola mwachangu. Chifukwa chake, zida ziyenera kukhala zokhoza kupanga zokutira zokhala ndi microstructure yolimba, kuchuluka kwa sp³ kwa machitidwe a ta-C kapena DLC, kusakanikirana kochepa komanso kukana bwino kwambiri. Kafukufuku wa mafilimu a diamondi a mabowo a PCB wasonyeza kuti mapangidwe apamwamba a diamondi amatha kusintha moyo wa kuboola ndi ubwino wa mabowo pokonza zipangizo za PCB zokhala ndi zodzaza za alumina ceramic.
Chofunika chachisanu ndi kubwerezabwereza bwino kwa kupaka utoto kuti upange zinthu zambiri. Mabowola ang'onoang'ono a PCB nthawi zambiri amapakidwa m'magulu akuluakulu, ndipo pulasitiki iliyonse iyenera kukhala ndi makulidwe ofanana a filimu, mtundu, kuuma, kumamatira komanso magwiridwe antchito a tribological. Kusiyana kulikonse kwa malo opangira, kuchuluka kwa plasma, momwe nthaka imakokolokera, kufalikira kwa mpweya kapena mphamvu ya bias kungayambitse kusiyana kwa magwiridwe antchito pakati pa mabowola. Chifukwa chake, makina opangira ma PCB micro-drills ayenera kukhala ndi magwiridwe antchito okhazikika a vacuum pumping, kuwongolera molondola kuyenda kwa plasma, kugawa kwa plasma kofanana, zida zodalirika zozungulira/kusintha komanso kuwongolera njira zophikira zomwe zingabwerezedwe. Kwa opanga zida, phindu lenileni la zida zopangira utoto sikuti limangopeza zotsatira zabwino za zitsanzo, komanso kusunga magwiridwe antchito okhazikika m'magulu opanga mosalekeza.
Chofunikira chachisanu ndi chimodzi ndi kapangidwe kapadera ka zida zazing'ono zolondola. Poyerekeza ndi nkhungu zazikulu kapena zida zodulira wamba, ma PCB micro-drill ndi ang'onoang'ono kwambiri, ofooka komanso osavuta kulondola kwa clamping. Choduliracho chiyenera kuonetsetsa kuti katunduyo ali ndi mphamvu zambiri popewa zotsatira zoteteza, kupaka kosagwirizana komanso kuwonongeka kwa makina. Kuzungulira kwa ma axis ambiri, kukonza katundu wolemera, malo olondola a zida komanso plasma yowoneka bwino ndikofunikira kuti pakhale kupaka kofanana pa nsonga ya drill ndi malo a flute. Kwa opanga omwe akufuna kugwiritsa ntchito mphamvu zambiri, zida zophikira ziyenera kulinganiza mphamvu ya batch ndi kufanana kwa filimu, m'malo mongowonjezera kuchuluka kwa katundu.
Kuphatikiza apo, zida zokutira za PCB micro-drill ziyenera kuthandizira kuphatikizana kwa njira zambiri. Dongosolo lophimba lopikisana siliyenera kukhala la mtundu umodzi wa filimu yokha. Liyenera kukhala lotha kuthandizira kuyeretsa kwa ma ion, kuyika kwa magawo osinthira, kuyika kwa zokutira zolimba, kuyika kwa zokutira zochokera ku kaboni ndi kapangidwe ka zokutira zambiri kapena zophatikizika. Mwachitsanzo, ta-C, DLC, AlTiN, AlCrN, TiAlSiN, CrN ndi zokutira zolimba zosakanikirana zitha kusankhidwa malinga ndi zida zosiyanasiyana za PCB, liwiro la kubowola, mainchesi a mabowo ndi zofunikira za makasitomala. Kusinthasintha kwa zida kumatsimikiza mwachindunji ngati wogulitsa zokutira angayankhe kusintha kwa zida za PCB ndi momwe kubowola kumachitikira.
Poganizira za kupanga ma PCB, cholinga chachikulu cha zokutira mabowo ang'onoang'ono ndikuchepetsa mtengo pa dzenje lililonse, kukulitsa nthawi ya zida, kukonza bwino makoma a mabowo, kuchepetsa ziphuphu ndi zolakwika za misomali, ndikukhazikitsa magwiridwe antchito obowola. Pamene ma PCB board akukhala ovuta kwambiri ndipo zipangizo zimakhala zovuta kuzipanga, zida zokutira ziyenera kusintha kuchoka ku machitidwe okhazikika ophimba olimba kupita ku nsanja zolondola kwambiri, zotsika mtengo, zotentha pang'ono komanso zobwerezabwereza kwambiri.
M'tsogolomu, mpikisano wa chophimba cha PCB micro-drill sudzadalira kokha kuuma kwa chophimba. Zidzadalira luso lonse la zida zophikira vacuum: plasma control, tinthu tosefera, kukhazikika kwa kutentha, uinjiniya womatira, kapangidwe ka zida, kubwerezabwereza kwa njira komanso kudalirika kopanga zinthu zambiri. Kwa opanga zida zophikira vacuum, izi ndi zovuta zaukadaulo komanso mwayi wamsika. Aliyense amene angapereke mayankho okhazikika, ogwira ntchito bwino komanso ogwiritsira ntchito PCB micro-drills adzapeza malo olimba m'mibadwo yotsatira yopanga PCB yapamwamba kwambiri.
