Ese Micro Drill yawe "irananiranye" muri 5G High-Frequency PCBs na IC Substrates?

Intangiriro: Kuva ku mikoranire y'abantu kugeza ku bibazo byo mu rwego rwa Micron

Bitewe n'iterambere ryihuse ry'itumanaho rya 5G, seriveri za AI, naikoranabuhanga rigezweho ryo gupakira,Inganda za PCB (Printed Circuit Board) zahindutse urubuga rukoresha ubucucike bwinshi, rukoresha microvia. Gukoresha HDI boards, multilayer PCBs, na IC Substrates bigaragaza ihinduka ry’igihe cyo gukora micro-scale, aho gucukura bigira uruhare rukomeye mu gushyiraho amashanyarazi yizewe (Via Interconnects). Ariko, uko umurambararo wo gucukura ugabanuka munsi ya mm 0.2 ndetse na mm 0.1, uburyo busanzwe bwo gukora imashini bugenda bunanirwa guhaza ibyifuzo by’ibikoresho bikoresha frequency nyinshi no gukora neza cyane, bigatuma ibikoresho bisaza, imashini ntoya zicika, ndetse n’ubwiza bw’urukuta rudahindagurika bigira ingaruka ku musaruro wa PCB no ku buryo buhamye bwo gukora.

Imbogamizi zo gutunganya ibikoresho mu gucukura mikorobe

Mu gukora PCB ifite ubucucike bwinshi, gucukura mikoro ni inzira ikomeye cyane igengwa n'imiterere y'ibikoresho, imikorere y'ibikoresho, n'uburyo bwo gukata. Ku muvuduko wo hejuru cyane, akenshi ukagera ku bihumbi mirongo kugeza ku bihumbi amagana bya RPM, uburyo buke cyane bwo gucukura mikoro butuma ishobora kwangirika cyane n'ubushyuhe, ibyo bigatuma ibikoresho byihuta, byongera ingano y'ubushyuhe, kandi bigatera imiterere idahindagurika yo gukata. Uko ubucucike bugenda bugabanuka, gukuraho ibikoresho bihinduka impinduka mu guhindura no gucika, bigatuma inkuta z'imyobo zigorama, imiterere y'ibice, no gufatana kwa resin, byose bikusanyirizwa mu miterere ya microvia nini kandi bigagabanya cyane ubudahangarwa bw'imikorere.

Iki kibazo kirushaho kugaragara iyo hakozwe ibikoresho bigezweho nka PTFE, BT resin, na ABF, aho modulus nke n'imiterere yo gufatana cyane bitera resin smear (Smear) n'ingaruka zo gufungana (Wicking) ku nkuta. Ibi birego bihindura imiterere y'imashini, bigahungabanya imiterere y'ibipimo, kandi bigira ingaruka mbi ku mikorere yo hasi harimo metallization na electroplating viability, bigatera ibyago bikomeye ku mikoreshereze yo ku rwego rwo hejuru nka IC Substrates, aho kwihanganira ibirego biri hasi cyane.

Guhitamo ikoranabuhanga ryo gusiga no gusiga ku butaka

Kugira ngo kunoze imikorere y’imashini nto, ubuhanga bwo gushushanya ubuso hakoreshejwe ikoranabuhanga rigezweho ryo gusiga ni ngombwa. Nubwo gusiga imashini zidafite amashanyarazi na CVD (Chemical Vapor Deposition) bishobora kongera ubukana bw’ubuso ku rugero runaka, bitanga imbogamizi mu mikoreshereze yabyo, harimo ubunini buke bwo gusiga imashini, ubushyuhe bwinshi bwo gusiga imashini, kwangirika kw’imashini, ndetse n’umuvuduko mwinshi usigara utuma imashini igabanya imashini mu gihe cy’imashini yihuta cyane.

Mu buryo bunyuranye, ikoranabuhanga rya PVD (Physical Vapor Deposition) Vacuum Coating Technology ritanga igisubizo cyiza cyane mu gukoresha uduce duto two gucukura, kuko rituma habaho gushyiramo uduce duto tw’udupira twinshi kandi duto dufite ubushobozi bwo gufata neza, kugabanya friction coefficient, no kongera ubushobozi bwo kwangirika, rigatuma inzira yo gukata ihagarara neza mu gihe rigabanya smear ya resin kandi rikongera ubuziranenge bw’inkuta z’umwobo.

Umuti wo gutwikira imashini nto ya Zhenhua Vacuum Micro Drill Coating

Sisitemu yo gusiga PVD ya MFA0605 yakozwe by'umwihariko kugira ngo ikoreshwe mu nganda za PCB. Ifite sisitemu yo gusuka ibyuma bya arc ion yakozwe ubwayo, ikuraho neza uduce duto twakozwe mu gihe cyo gushyiramo, ikerekana ko filime ari nziza kandi ikora neza. Sisitemu ishyigikira Ta-C (tetrahedral amorphous coatings) iteye imbere, itanga ubukana bwinshi kugeza kuri 63 GPa, hamwe n'ubushobozi buke bwo gukururana, kurwanya ingese neza, no kumara igihe kirekire cyane ibikoresho. Muri icyo gihe, irashobora gushyiramo ubwoko bwinshi bw'imyenda ikora neza nka AlTiN, AlCrN, TiCrAlN, TiAlSiN, na CrN, bigatuma ikoreshwa neza mu gukaraba uduce duto twa PCB, ibikoresho byo gukata, imashini zikora neza, n'ibice by'imodoka, mu gihe ikomeza gufatana neza, ikagira imiterere myiza, kandi ikora neza mu buryo bworoshye mu bikorerwa mu bwinshi.

Umwanzuro

Uko inganda za PCB zikomeza gutera imbere zigana ku bucucike bwinshi, imiyoboro mito, n'inyubako zigoye kurushaho, ubushobozi bwo gucukura mito bwabaye ikintu cy'ingenzi mu bwiza bw'umusaruro no guhangana. Muri uru rwego, gupfuka ibikoresho ntabwo bikiri inyongeramusaruro ahubwo ni ikoranabuhanga rikomeye rigena mu buryo butaziguye igihe ibikoresho bimara, ubwiza bw'imyobo, n'uburyo ibintu bihora bihagaze muri rusange. Dukoresheje ikoranabuhanga rya PVD Vacuum Coating, Zhenhua Vacuum ikomeza kunoza uburyo bwo gupfuka ibikoresho, kudahungabana kwa firime, no gukora neza, bigatuma habaho imikorere yizewe mu bikoresho bikoresha frequency nyinshi no gucukura mikorobe nziza cyane.
