Kodi Micro Drill Yanu "Ikulephera" mu 5G High-Frequency PCBs ndi IC Substrates?

Mau Oyamba: Kuchokera ku Ma Interconnects mpaka ku Mavuto a Micron-Level

Ndi kupita patsogolo mwachangu kwa kulumikizana kwa 5G, ma seva a AI, ndiukadaulo wapamwamba wopaka,Kupanga ma PCB (Printed Circuit Board) kwasanduka nsanja yolimba kwambiri, yoyendetsedwa ndi microvia. Kugwiritsa ntchito ma HDI board, ma multilayer PCB, ndi ma IC Substrates kukuwonetsa kusintha kwa nthawi yopanga ma micron-scale, komwe kudzera mu kubowola kumachita gawo lofunikira popanga ma interlayer electrical connections odalirika (Via Interconnects). Komabe, pamene ma diameter abowola akuchepa pansi pa 0.2 mm komanso 0.1 mm, njira zamakono zopangira machining zikulephera kukwaniritsa zofunikira za zipangizo zama frequency apamwamba komanso kupanga molondola kwambiri, zomwe zimapangitsa kuti zida zisagwire bwino ntchito, kusweka kwa ma micro drill, komanso zovuta zazikulu zomwe zimakhudza kukolola kwa PCB komanso kusinthasintha kwa kupanga.

Mavuto Okhudza Kuboola Microvia

Mu kupanga ma PCB okhala ndi kuchuluka kwakukulu, kuboola kwaching'ono ndi njira yovuta kwambiri yolamulidwa ndi momwe zida zilili, momwe zinthu zilili, komanso momwe zimadulira. Pa liwiro la spindle lokwera kwambiri, nthawi zambiri limafika pa masauzande ambiri mpaka mazana masauzande ambiri a RPM, kuchepa kwa malire odulira kwaching'ono kumapangitsa kuti zikhale zosavuta kukhudzidwa ndi kutentha, zomwe zimathandizira kuwonongeka kwa zida, zimawonjezera kuchuluka kwa kukangana, komanso zimapangitsa kuti kudula kusakhazikika. Pamene malire odulira akuchepa, kuchotsa zinthu kumasintha kukhala kusintha ndi kung'ambika, zomwe zimapangitsa kuti khoma la mabowo likhale lolimba, kupangika kwa burr, ndi kumatirira kwa resin, zonse zomwe zimasonkhana pa microvia arrays yolimba ndikuchepetsa kwambiri kukhazikika kwa njira.

Vutoli limaonekera kwambiri mukamagwiritsa ntchito zinthu zapamwamba monga PTFE, BT resin, ndi ABF, pomwe ma modulus ochepa komanso mawonekedwe omatira kwambiri amalimbikitsa resin smear (Smear) ndi zotsatira za wicking (Wicking) m'makoma. Zolakwika izi zimasokoneza kudzera mu geometry, zimapangitsa kuti kulondola kwa miyeso kukhale kochepa, komanso kumakhudza kwambiri njira zotsatizana kuphatikizapo metallization ndi electroplating reliability, zomwe zimapangitsa kuti pakhale zoopsa zazikulu pa ntchito zapamwamba monga IC Substrates, komwe kulekerera zolakwika kumakhala kochepa kwambiri.

Kusankha Ukadaulo Wapamwamba ndi Ukadaulo Wopaka

Kuti zinthu ziyende bwino pogwiritsa ntchito njira zamakono zopangira zinthu, ukadaulo wa pamwamba pogwiritsa ntchito ukadaulo wapamwamba wopangira zinthu n'kofunika kwambiri. Ngakhale kuti kuyika zinthu popanda kugwiritsa ntchito magetsi ndi CVD (Chemical Vapor Deposition) kungapangitse kuti pamwamba pakhale kuuma pang'ono, zimakhala ndi zoletsa pakugwiritsa ntchito zinthu zazing'ono, kuphatikizapo kufanana kwa makulidwe a zinthu, kutentha kwambiri, kuwonongeka kwa zinthu zomwe zingachitike, komanso kupsinjika kwakukulu komwe kumabweretsa kusokonekera kwa zinthu zomwe zimagwiritsidwa ntchito popanga zinthu mwachangu.

Mosiyana ndi zimenezi, ukadaulo wa PVD (Physical Npor Deposition) Vacuum Coating Technology umapereka njira yoyenera kwambiri yogwiritsira ntchito kubowola zinthu zazing'ono, chifukwa umathandiza kuti mafilimu okhuthala, ofanana, komanso opapatiza azikhala olimba, zomwe zimathandiza kuti kudula kukhale kolimba komanso kuchepetsa kukhuthala kwa makoma a mabowo.

Zhenhua Vacuum Micro Drill Coating Solution

Dongosolo Lophimba la MFA0605 PVD lapangidwa makamaka kuti ligwiritsidwe ntchito popanga zida zophimba bwino kwambiri mumakampani opanga ma PCB. Lili ndi makina osefera a arc ion omwe adapangidwa okha, limachotsa bwino tinthu tating'onoting'ono tomwe timapangidwa panthawi yoyika, ndikuwonetsetsa kuti filimuyo ndi yabwino kwambiri komanso kuti igwirizane bwino. Dongosololi limathandizira zophimba zapamwamba za Ta-C (tetrahedral amorphous carbon), zomwe zimapangitsa kuti zikhale zolimba kwambiri mpaka 63 GPa, komanso kuti zikhale ndi coefficient yotsika, kukana dzimbiri bwino, komanso kukhala ndi moyo wautali kwambiri pazida. Nthawi yomweyo, imatha kusunga mitundu yosiyanasiyana ya zophimba zapamwamba monga AlTiN, AlCrN, TiCrAlN, TiAlSiN, ndi CrN, zomwe zimapangitsa kuti ikhale yosinthika kwambiri pakugwiritsa ntchito ma PCB micro drills, zida zodulira, mawonekedwe olondola, ndi zida zamagalimoto, pomwe imasunga kulimba kolimba, kusinthasintha kwabwino kwa batch, komanso magwiridwe antchito ochepetsera filimu m'malo opangira zinthu zambiri.

Mapeto

Pamene kupanga ma PCB kukupitilira kupita patsogolo ku kuchuluka kwa ma via ang'onoang'ono, ndi nyumba zovuta kwambiri, luso loboola zinthu zazing'ono lakhala chinthu chofunikira kwambiri pakupanga zinthu komanso mpikisano. Pachifukwa ichi, kupaka zida sikulinso kowonjezera koma ndi ukadaulo wofunikira kwambiri womwe umatsimikiza mwachindunji nthawi ya zida, ubwino wa mabowo, komanso kukhazikika kwa njira yonse. Pogwiritsa ntchito ukadaulo wa PVD Vacuum Coating Technology, Zhenhua Vacuum imapititsa patsogolo kufanana kwa kupaka, kukhazikika kwa filimu, komanso kukhazikika kwa kupanga, zomwe zimathandiza kuti zinthu zizigwira ntchito bwino kwambiri komanso kuboola zinthu zazing'ono kwambiri.
