Kule mihla, ngohlaziyo olukhawulezayo lweemveliso zombane, ukushicilelwa kweePCB kwandisiwe ukusuka kwiibhodi ezinomaleko omnye ukuya kwiibhodi ezinomaleko kabini kunye neebhodi ezinomaleko amaninzi ezineemfuno ezichanekileyo. Ngoko ke, kukho iimfuno ezingakumbi zokucutshungulwa kwemingxuma yebhodi yesekethe, njengale: ububanzi bomngxuma buba buncinci kwaye buncinci, kwaye umgama phakathi komngxuma kunye nomngxuma uya uncinci kwaye uncinci. Kuyaqondwa ukuba umzi-mveliso webhodi okwangoku usebenzisa i-epoxy resin-based composite materials. Inkcazo yobukhulu bomngxuma kukuba ububanzi bungaphantsi kwe-0.6 mm kwimingxuma encinci kunye ne-0.3 mm ye-micropores. Namhlanje ndiza kwazisa indlela yokucubungula imingxuma encinci: ukugaya ngomatshini.
Ukuze kuqinisekiswe ukusebenza kakuhle okuphezulu kunye nomgangatho womngxuma, sinciphisa inani leemveliso ezingalunganga. Kwinkqubo yokugaya oomatshini, izinto ezimbini, amandla e-axial kunye ne-torque yokusika, kufuneka ziqwalaselwe, ezinokuchaphazela ngokuthe ngqo okanye ngokungathanga ngqo umgangatho womngxuma. I-axial force kunye ne-torque iya kunyuka kunye nokutya kunye nobukhulu boluhlu lokusika, ngoko isantya sokusika siya kwanda, ukwenzela ukuba inani leefayili ezinqunywe ngexesha leyunithi liya kwanda, kwaye isixhobo sokugqoka siya kwanda ngokukhawuleza. Ngoko ke, ubomi be-drill buhluke kwimingxuma yobukhulu obuhlukeneyo. Umsebenzisi kufuneka aqhelane nokusebenza kwesixhobo kwaye atshintshe i-drill ngexesha. Yiyo loo nto iindleko zokusetyenzwa kweemingxuma ezincinci ziphezulu.
Kwi-axial force, i-static component FS ichaphazela ukusika kwe-Guangde, ngelixa i-FD yecandelo eliguquguqukayo lichaphazela kakhulu ukusika kweyona nto iphambili. Icandelo eliguquguqukayo le-FD linempembelelo enkulu kumphezulu woburhabaxa kunecandelo elimileyo iFS. Ngokuqhelekileyo, xa i-aperture yomngxuma owenziwe ngaphambili ingaphantsi kwe-0.4mm, i-static component FS iyancipha ngokukhawuleza ngokunyuka kwe-aperture, ngelixa i-trend yecandelo eliguqukayo le-FD liyancipha lisicaba.
Ukunxitywa kwe-PCB drill inxulumene nesantya sokusika, izinga lokutya, kunye nobukhulu bendawo yokubeka. Umlinganiselo weradiyasi ye-drill bit ukuya kububanzi befiber yeglasi inempembelelo enkulu kubomi besixhobo. Ubukhulu bomlinganiselo, ubukhulu bobubanzi be-fiber bundle esikwe sisixhobo, kunye nokunyuka kwesixhobo sokunxiba. Kwizinto eziphathekayo, ubomi be-drill ye-0.3mm bunokwemba imingxuma engama-3000. I-drill inkulu, imingxuma embalwa igrunjwa.
Ukuze kuthintelwe iingxaki ezinje nge-delamination, umonakalo eludongeni lomngxuma, amabala, kunye nee-burrs xa kusetyenzwa, sinokuqala sibeke i-2.5 mm yobukhulu bepad phantsi komaleko, sibeke ipleyiti yobhedu phezu kwepadi, kwaye emva koko Beka iphepha le-aluminium phezu ibhodi yobhedu. Indima yephepha le-aluminium yi-1. Ukukhusela umphezulu webhodi kwi-scratches. 2. Ukutshatyalaliswa kobushushu obuhle, i-drill bit iya kuvelisa ubushushu xa ubhobhoza. 3. Isiphumo sokuphazamisa / isiphumo sokomba ukunqanda umngxuma wokutenxa. Indlela yokunciphisa i-burrs kukusetyenziswa kwetekhnoloji yokwemba i-vibration, usebenzisa i-carbide drill ukubhola, ubunzima obuhle, kunye nobukhulu kunye nesakhiwo sesixhobo kufuneka sihlengahlengiswe.
