HDI: High Kachulukidwe interconnection wa chidule, mkulu-kachulukidwe interconnection, sanali makina kubowola, yaying'ono-khungu dzenje mphete mu 6 mil kapena zochepa, mkati ndi kunja kwa interlayer mawaya mzere m'lifupi / mzere kusiyana mu 4 mil kapena zochepa, PAD. m'mimba mwake osapitirira 0.35mm multilayer board board amatchedwa HDI board.
Akhungu kudzera: mwachidule kwa Blind kudzera, amazindikira kulumikizana pakati pa zigawo zamkati ndi zakunja.
Kukwiriridwa kudzera: mwachidule Kukwiriridwa kudzera, kuzindikira kugwirizana pakati pa wosanjikiza wamkati ndi wosanjikiza wamkati.
Akhungu kudzera makamaka dzenje laling'ono ndi awiri a 0.05mm ~ 0.15mm, kukwiriridwa kudzera amapangidwa ndi laser, plasma etching ndi photoluminescence, ndipo kawirikawiri amapangidwa ndi laser, amene amagawidwa mu CO2 ndi YAG ultraviolet laser (UV).
HDI board zinthu
1.HDI mbale chuma RCC, LDPE, FR4
RCC: lalifupi la Resin TACHIMATA mkuwa, utomoni wokutira zojambulazo zamkuwa, RCC imapangidwa ndi zojambulazo zamkuwa ndi utomoni zomwe pamwamba pake zakhala zowuma, zosagwira kutentha, zosagwira makutidwe ndi okosijeni, ndi zina zambiri, ndipo mawonekedwe ake akuwonetsedwa pachithunzi pansipa: (chogwiritsidwa ntchito pamene makulidwe ake ndi oposa 4mil)
Wosanjikiza utomoni wa RCC ali processability chimodzimodzi monga FR-1/4 bonded mapepala (Prepreg).Kuphatikiza pakukwaniritsa zofunikira zogwirira ntchito za multilayer board ya njira yodziunjikira, monga:
(1) High kutchinjiriza kudalirika ndi yaying'ono-kuchititsa dzenje kudalirika;
(2) Kutentha kwapamwamba kwa galasi (Tg);
(3) Mayamwidwe otsika a dielectric komanso otsika madzi;
(4) High adhesion ndi mphamvu kwa zojambulazo mkuwa;
(5) Uniform makulidwe a kutchinjiriza wosanjikiza pambuyo kuchiritsa.
Pa nthawi yomweyo, chifukwa RCC ndi mtundu watsopano wa mankhwala popanda galasi CHIKWANGWANI, ndi bwino etching dzenje mankhwala ndi laser ndi madzi a m'magazi, amene ndi wabwino kulemera kuwala ndi kupatulira kwa multilayer bolodi.Kuphatikiza apo, chojambula chamkuwa chokhala ndi utomoni chimakhala ndi zojambulazo zopyapyala zamkuwa monga 12pm, 18pm, etc., zomwe ndizosavuta kuzikonza.
Chachitatu, PCB yadongosolo loyamba, yachiwiri ndi chiyani?
Izi zoyamba, zachiwiri zimatanthawuza kuchuluka kwa mabowo a laser, kuthamanga kwa PCB pachimake kangapo, kusewera mabowo angapo a laser!Ndi malamulo ochepa.Monga momwe zilili pansipa
1,.Kukanikiza kamodzi mutatha kubowola mabowo == "kunja kwa makina osindikizira kamodzinso zojambulazo zamkuwa == "ndiyeno laser kubowola mabowo
Ili ndilo gawo loyamba, monga momwe chithunzi chili pansipa
2, mutatha kukanikiza kamodzi ndikubowola mabowo == "kunja kwa zojambula zina zamkuwa == "ndiyeno laser, mabowo oboola == "wosanjikiza wakunja wa zojambula zina zamkuwa == "ndiyeno laser kubowola mabowo
Ili ndi dongosolo lachiwiri.Nthawi zambiri zimangotengera kangati mumayika laser, ndiye masitepe angati.
Chachiwiri dongosolo ndiye ogaŵikana zakhala zikuzunza m'miyoyo mabowo ndi kugawanika mabowo.
Chithunzi chotsatirachi ndi zigawo zisanu ndi zitatu za mabowo otsatiridwa achiwiri, ndi magawo 3-6 oyamba osindikizira, kunja kwa 2, 7 zigawo zopanikizidwa, ndikugunda mabowo a laser kamodzi.Kenako zigawo za 1,8 zimapanikizidwa ndikukhomeredwa ndi mabowo a laser kamodzinso.Izi ndi kupanga mabowo awiri a laser.Mtundu uwu wa dzenje chifukwa zakhala zakhala zikuzunza m'miyoyo, ndondomeko vuto adzakhala apamwamba pang'ono, mtengo ndi apamwamba pang'ono.
Chithunzi m'munsimu chikusonyeza zigawo zisanu ndi zitatu za yachiwiri-kuti mtanda mabowo akhungu, izi processing njira ndi ofanana pamwamba zigawo zisanu ndi zitatu za yachiwiri kuti zakhala zikuzunza m'miyendo mabowo, ayeneranso kugunda mabowo laser kawiri.Koma mabowo laser si zakhala zikuzunza m'miyoyo pamodzi, vuto processing ndi zochepa kwambiri.
Lachitatu, dongosolo lachinayi ndi zina zotero.
