Njengoko ukwenziwa kwe-PCB kuqhubela phambili kuxinano oluphezulu, isithuba esincinci semigca, ukubalwa kwamaleko aphezulu kunye nemigangatho yomgangatho wemingxuma efuna umgudu onzima, ukubhola okuncinci kube yenye yezona nkqubo zibalulekileyo ezichaphazela isivuno, ukuchaneka kobukhulu kunye neendleko zemveliso. Kwi-PCB yokubhola ngesantya esiphezulu, kufuneka ukubhola okuncinci ukuze kunqunyulwe i-copper foil, i-glass fiber, iinkqubo ze-resin kunye nezixhobo zokuzalisa ezirhabaxa ngakumbi ngelixa kugcinwa imiphetho ebukhali yokusika, ukukhutshwa kwe-chip ezinzileyo kunye nomgangatho wodonga lwemingxuma ohambelanayo. Iingxelo zoshishino ziphawule ukuba kwi-PCB yokubhola okuxineneyo, ukungaphumeleli kokubhola kunxulunyaniswa ngokusondeleyo nokunamathela kwe-resin, ukuguguleka komphetho ngokukhawuleza, ukuguqulwa kwemingxunya kunye nokutshintshwa kwezixhobo rhoqo, ingakumbi njengoko isantya sokubhola kunye nenani lamaleko liqhubeka lisanda.
Ngesi sizathu,Ugqunywe nge-PCB micro-drillAkuseyonkqubo elula "yokumelana nokuguguleka komaleko". Iba sisisombululo sobunjineli bomphezulu ochanekileyo esifuna ukusebenza okuphezulu kakhulu kwizixhobo zokugquma nge-vacuum. Ingubo kufuneka iphucule ubulukhuni, inciphise ukungqubana, icinezele ukunamathela kwe-resin okwakhelwe ngaphakathi, iphucule ukugcinwa komphetho kwaye igcine i-geometry yokuqala yeedrili ze-carbide ezincinci. Oku kubeka iimfuno ezintsha kulawulo lwesakhiwo sefilimu, uzinzo lweplasma, ucinezelo lwamasuntswana, ulawulo lobushushu kunye nokuhambelana kwebhetshi.
Imfuneko yokuqala kukulawula ukugquma okubhityileyo kakhulu nokulinganayo. Ii-PCB micro-drills zine-diameters ezincinci kakhulu, imiphetho yokusika ebukhali kunye nejometri ezintsonkothileyo zeflute. Ubukhulu obugqithisileyo bokugquma bunokujikeleza umphetho wokusika, buchaphazele ukususwa kweetships okanye butshintshe indawo yokusika eyilelweyo. Ke ngoko, izixhobo zokugquma kufuneka zikwazi ukufaka iifilimu ezixineneyo, eziqhubekayo nezifanayo kwisikali se-micron okanye nakwi-sub-micron, ngelixa ziqinisekisa ukugquma okuhle kumphetho wokusika, umphezulu weflute kunye nencam yokubhola. Kwiingubo ezifana ne-ta-C, i-DLC, i-AlTiN, i-AlCrN, i-TiAlSiN okanye iingubo eziqinileyo ze-multilayer, izixhobo kufuneka zilawule ngokuchanekileyo izinga lokufaka, amandla e-ion kunye nobukhulu befilimu ukuze zilinganisele ubunzima, ukunamathela kunye nobukhali bomphetho.
Imfuneko yesibini kukukwazi ukukhupha iinxalenye ezincinci. Ukufakwa kwee-arc ze-cathodic zemveli kunika izinga eliphezulu le-ionization kunye nokunamathela okuqinileyo kwefilimu, kodwa ii-macroparticles zinokuba ngumthombo obalulekileyo weziphene kwizixhobo ezincinci. Kwi-PCB micro-drills, kwanamaqhekeza amancinci akwicala lokusika anokubangela uxinzelelo lwendawo, ukubhola okungazinzi, imikrwelo yodonga lwemingxunya okanye ukungaphumeleli kokufaka ngaphambi kwexesha. Yingakho ubuchwepheshe be-arc ehluziweyo ngemagnethi, iinkqubo ze-arc ye-cathodic vacuum ehluziweyo kunye nezakhiwo zokucoca ze-plasma ezilungisiweyo zibaluleke ngakumbi. Ukucoca ngemagnethi kunokunciphisa amaqhekeza amakhulu kwaye kuphucule ukuguda kwe-coating, okubaluleke kakhulu kwi-DLC kunye ne-ta-C superhard coatings ezisetyenziswa kwi-micro-drills.
Imfuneko yesithathu kukunamathela okuqinileyo ngaphandle komonakalo wobushushu. Ii-PCB micro-drills zihlala zenziwe nge-carbide eqinisiweyo, kwaye ukusebenza kwazo kokusika kuxhomekeke kakhulu kwi-edge geometry echanekileyo yomhlaba. Ukuba ubushushu bokugquma buphezulu kakhulu, i-substrate, isakhiwo esiqinisiweyo okanye ukuchaneka komphetho kunokuchaphazeleka. Izixhobo zokugquma ze-micro-drill zanamhlanje ke ngoko zifuna ukufakwa kobushushu obuphantsi okuzinzileyo, ukucoca ii-ion okusebenzayo kakhulu kunye noyilo oluthembekileyo lwe-interlayer. Ubuchwephesha obufana nokugrumba umthombo we-ion, ukufakwa kwe-bias-assisted, ii-Cr okanye ii-metal transition layers, kunye nee-interlayer ezilinganisiweyo zinceda ukuphucula amandla okubopha phakathi kwe-coating kunye ne-carbide substrate. Ezinye iinkqubo zokugquma ze-ta-C ezihluziweyo zinokufakwa ngaphantsi kwe-100 °C, zinceda ukugcina i-geometry yee-carbide drills ezincinci.
Imfuneko yesine bubunzima obuphezulu obudityaniswe nokungqubana okuphantsi. Kwi-PCB drilling, i-coating kufuneka imelane nokuguguleka okurhabaxa okuvela kwi-glass fiber, copper, resin kunye ne-ceramic fillers, ngelixa ikwanciphisa ubushushu bokungqubana kunye nokunamathela kwe-resin. Ifilimu eqinileyo kodwa erhabaxa inokunyusa ukumelana nokusika kwaye ikhawulezise ukuvaleka kwee-chip. Ifilimu egudileyo kodwa engenamandla okuthwala umthwalo inokusilela ngokukhawuleza phantsi kokugrumba okukhawulezayo. Ke ngoko, izixhobo kufuneka zikwazi ukuvelisa i-coating ene-microstructure eninzi, umxholo ophezulu we-sp³ kwiinkqubo ze-ta-C okanye ze-DLC, i-coefficient ephantsi yokungqubana kunye nokumelana okugqwesileyo kokuguguleka. Uphando kwiifilimu zedayimani ze-PCB drills lubonise ukuba izakhiwo zedayimani ezikumgangatho ophezulu zinokuphucula ubomi bokugrumba kunye nomgangatho wemingxunya xa kulungiswa izixhobo ze-PCB ezirhabaxa ezine-alumina ceramic fillers.
Imfuneko yesihlanu kukuphindaphindwa kakuhle kwengubo yokwaleka ukuze kwenziwe imveliso enkulu. Ii-PCB micro-drills zihlala zigqunywe ngeebhetshi ezinkulu, kwaye yonke i-drill kufuneka igcine ubukhulu befilimu obuhambelanayo, umbala, ubulukhuni, ukunamathela kunye nokusebenza kwe-tribological. Naluphi na umahluko kwindawo ye-fixture, uxinano lwe-plasma, imeko yokukhukuliseka kwethagethi, ukusasazwa kokuhamba kwegesi okanye i-bias voltage kunokukhokelela kumahluko ekusebenzeni phakathi kwee-drills. Ke ngoko, iinkqubo ze-coating ze-PCB micro-drills kufuneka zibe nokusebenza okuzinzileyo kwe-vacuum pumping, ulawulo oluchanekileyo lokuhamba kobunzima, ukusasazwa kwe-plasma efanayo, izixhobo ezithembekileyo zokujikeleza/ukuguquka kunye nolawulo lweresiphi oluphindaphindwayo. Kubavelisi bezixhobo, ixabiso lokwenyani lezixhobo ze-coating alikho nje ekufezekiseni iziphumo ezilungileyo zesampulu, kodwa likwagcina ukusebenza okuzinzileyo kwiibhetshi zemveliso eziqhubekayo.
Imfuneko yesithandathu kuyilo olukhethekileyo lwezixhobo zokufaka kunye nokulayisha izixhobo ezincinci ezichanekileyo. Xa kuthelekiswa neenkuni ezinkulu okanye izixhobo zokusika eziqhelekileyo, ii-PCB micro-drills zincinci kakhulu, zibuthathaka kwaye zinovelwano ngakumbi kukuchaneka kokubambelela. Isixhobo kufuneka siqinisekise ukuba sinomthamo ophezulu wokulayisha ngelixa siphepha iziphumo zokukhusela, ukugquma okungalinganiyo kunye nomonakalo woomatshini. Ukujikeleza kwe-multi-axis, ulungiselelo lomthwalo oxineneyo, ukubeka izixhobo ngokuchanekileyo kunye nokuvezwa kweplasma okulungelelanisiweyo kuyimfuneko ukuze kufezekiswe ukugquma okufanayo kwincam yokubhola kunye nendawo yeflute. Kubavelisi abalandela ukukhupha okuphezulu, izixhobo zokufaka kufuneka zilinganise umthamo webhetshi kunye nokufana kwefilimu, endaweni yokwandisa nje ubungakanani bomthwalo.
Ukongeza, izixhobo zokugquma ezincinci ze-PCB kufuneka zixhase ukuhlanganiswa kweenkqubo ezininzi. Inkqubo yokugquma ekhuphisanayo akufuneki ithintelwe kuhlobo olunye lwefilimu. Kufuneka ikwazi ukuxhasa ukucocwa kwe-ion, ukufakwa kweleya yotshintsho, ukufakwa kweleya eqinileyo, ukufakwa kweleya esekwe kwikhabhoni kunye noyilo lweleya eninzi okanye edibeneyo. Umzekelo, i-ta-C, i-DLC, i-AlTiN, i-AlCrN, i-TiAlSiN, i-CrN kunye neengubo eziqinileyo ze-hybrid zinokukhethwa ngokwezixhobo ezahlukeneyo ze-PCB, isantya sokugqobhoza, ububanzi bemingxuma kunye neemfuno zabathengi. Ukuguquguquka kwezixhobo kumisela ngokuthe ngqo ukuba umthengisi wengubo unokuphendula na kwizixhobo ze-PCB ezitshintshayo kunye neemeko zokugqobhoza.
Ngokwembono yokwenziwa kwePCB, injongo ephambili yokufakelwa kwe-micro-drill coating kukunciphisa iindleko ngomngxuma ngamnye, ukwandisa ubomi besixhobo, ukuphucula umgangatho wodonga lwemingxunya, ukunciphisa ii-burrs kunye neziphene ze-nail-heading, kunye nokuzinzisa ukusebenza kokugrumba. Njengoko iibhodi ze-PCB zisiba nzima ngakumbi kwaye izixhobo ziba nzima ngakumbi ukuzisebenzisa ngomatshini, izixhobo zokugrumba kufuneka ziguquke ukusuka kwiinkqubo zesiqhelo zokugrumba eziqinileyo ziye kumaqonga obunjineli bomphezulu obuchanekileyo, obuphantsi, obuphantsi kunye nobuphindaphindwayo kakhulu.
Kwixesha elizayo, ukukhuphisana kwe-PCB micro-drill coating akuyi kuxhomekeka kuphela kubulukhuni be-coating. Kuya kuxhomekeka kubuchule obupheleleyo bezixhobo ze-vacuum coating: ulawulo lwe-plasma, ukuhluzwa kwamasuntswana, uzinzo lobushushu, ubunjineli bokunamathela, uyilo lwe-fixture, ukuphindaphindwa kwenkqubo kunye nokuthembeka kwemveliso ngobuninzi. Kubavelisi bezixhobo ze-vacuum coating, oku kungumceli mngeni wobugcisa kunye nethuba lemarike. Nabani na onokubonelela ngezisombululo ze-coating ezizinzileyo, ezisebenza kakuhle nezijolise kwisicelo se-PCB micro-drills uya kufumana isikhundla esomeleleyo kwisizukulwana esilandelayo semveliso ye-PCB ephezulu.
