Nhanganyaya: Kubva paInterconnects kusvika kuMicron-Level Challenges
Nekufambira mberi nekukurumidza kwekutaurirana kwe5G, maseva eAI, uyematekinoroji epamusoro ekurongedza,Kugadzira PCB (Printed Circuit Board) kwashanduka kuita puratifomu ine vanhu vakawanda, inotungamirwa ne microvia. Kushandiswa kwemaHDI boards, multilayer PCBs, uye IC Substrates zvinoratidza shanduko kuenda kunguva yekugadzira micron-scale, uko kuburikidza nekuboora kunoita basa guru mukugadzira interlayer electrical interlayer interconnections (Via Interconnects). Zvisinei, sezvo dhayamita yekuboora ichiderera pasi pe0.2 mm uye kunyange 0.1 mm, nzira dzechinyakare dzekugadzira dziri kuramba dzichitadza kusangana nezvinodiwa nezvinhu zvine frequency yakakwira uye kugadzirwa kwakanyatsojeka, zvichiita kuti zvishandiso zvisakanganise, micro drill break, uye kusagadzikana kwemadziro emadziro emhando yegomba zvinokanganisa goho rePCB uye kugadzikana kwekugadzira.
Matambudziko Ekugadzirisa muMicrovia Drilling
Mukugadzirwa kwePCB ine density yakakura, kucherwa kwemicro ibasa rinoitwa nehunyanzvi hunonyanya kudzorwa nemamiriro ezvishandiso, maitiro ezvishandiso, uye kushanduka kwekucheka. Pakumhanya kwespindle kwakanyanya, kazhinji kusvika makumi ezviuru kusvika mazana ezviuru zveRPM, kucheka kushoma kwemicro drills kunoita kuti zvive nyore kubatwa nekupisa, izvo zvinokurumidzisa kupera kwezvishandiso, kuwedzera coefficient of friction, uye kutungamira kumamiriro ekucheka asina kugadzikana. Sezvo cutting edge ichiderera, kubviswa kwezvinhu kunoshanduka kuita deformation uye kubvaruka, zvichikonzera maburi roughness, burr formation, uye resin adhesion, zvese izvi zvinoungana pa dense microvia arrays uye zvinoderedza zvakanyanya kugadzikana kweprocess.
Dambudziko iri rinonyanya kuoneka kana uchishandisa zvinhu zvepamusoro zvakaita sePTFE, BT resin, uye ABF, uko modulus shoma uye hunhu hwekunamatira kwakanyanya zvinokurudzira resin smear (Smear) uye wicking effects (Wicking) pamadziro. Kukanganisa uku kunokanganisa kuburikidza ne geometry, kukanganisa dimensional accuracy, uye kukanganisa maitiro epasi anosanganisira metallization uye electroplating reliability, zvichikonzera njodzi huru kumashandisirwo epamusoro senge IC Substrates, uko kushivirira kwezvikanganiso kwakaderera zvakanyanya.
Sarudzo yeUinjiniya hwepamusoro uye Tekinoroji yeKuputira
Kuti zvivandudze mashandiro ekugadzira ma micro drill, hunyanzvi hwepamusoro hwekugadzira pamusoro pevhu kuburikidza nehunyanzvi hwepamusoro hwekuputira hunokosha. Kunyange hazvo electroless plating uye CVD (Chemical Vapor Deposition) zvichigona kuwedzera kuomarara kwevhu kusvika pamwero wakati, zvine zvipingamupinyi mukushandiswa kwema micro-scale, kusanganisira kusakwana kweukobvu hwepurasitiki, tembiricha yakakwira, kukuvara kwe substrate, uye kushushikana kwakanyanya kunotungamira mukubviswa kwepurasitiki pasi pemamiriro ekugadzira nekukurumidza.
Kusiyana neizvi, PVD (Physical Vapor Deposition) Vacuum Coating Technology inopa mhinduro yakakodzera kune micro drilling applications, sezvo ichigonesa kuisa mafirimu matete akaenzana, akasimba uye ane kunamira kwakanaka, kuderedza friction coefficient, uye kuwedzera kusakara, zvichigadzirisa maitiro ekucheka uku zvichideredza resin smear uye zvichivandudza kusimba kwemadziro emakomba.
Zhenhua Vacuum Micro Drill Coating Solution
Iyo MFA0605 PVD Coating System yakagadzirwa zvakanangana nekushandiswa kwezvishandiso zvekuputira maturusi zvine simba guru muindasitiri yePCB. Yakashongedzerwa ne arc ion plating filtering system yakazvigadzira, inobvisa zvinobudirira macro-particles anogadzirwa panguva yekuiswa, ichivimbisa kunaka kwefirimu uye kufanana kwe coating. Sisitimu iyi inotsigira advanced Ta-C (tetrahedral amorphous carbon) coatings, ichipa kuomarara kwakanyanya kusvika ku63 GPa, pamwe chete ne low friction coefficient, high corrosion resistance, uye yakareba zvakanyanya hupenyu hwezvishandiso. Panguva imwe chete, inokwanisa kuisa akasiyana-siyana e high-performance coatings akadai seAlTiN, AlCrN, TiCrAlN, TiAlSiN, uye CrN, zvichiita kuti ikwanise kushandiswa zvakanyanya paPCB micro drills, cutting tools, precision molds, uye automotive components, uku ichichengetedza stable coating adhesion, batch consistency yakanaka, uye high-efficiency thin film deposition performance munzvimbo dzekugadzira zvakawanda.
Mhedziso
Sezvo kugadzirwa kwePCB kuri kuramba kuchifambira mberi kusvika pakuwanda kwehuwandu, ma via madiki, uye zvivakwa zvakaoma, kugona kubhowa kwe micro drilling kwave chinhu chinonyanya kukosha mumhando yekugadzira uye kukwikwidzana. Mumamiriro ezvinhu aya, kupfekedza maturusi hakusisiri kuwedzera kwekuwedzera asi tekinoroji yakakosha inogonesa iyo inosarudza zvakananga hupenyu hwematurusi, mhando yemaburi, uye kugadzikana kwese kwemaitiro. Ichishandisa tekinoroji yePVD Vacuum Coating, Zhenhua Vacuum inoramba ichivandudza kufanana kwe coating, kugadzikana kwefirimu, uye kugadzikana kwekugadzirwa, zvichiita kuti ishande zvakanaka muzvinhu zvine frequency yakakwira uye kubhowa kwe microvia kwakanyatsonaka.
