I. Menene allon HDI?
HDI allon (High Density Interconnector), wato, babban haɗin haɗin haɗin gwiwa, shine amfani da fasahar rami da aka binne micro-makafi, allon kewayawa tare da babban adadin rarraba layi.Jirgin HDI yana da layi na ciki da na waje, sannan kuma amfani da hakowa, haɓaka ramuka da sauran matakai, ta yadda kowane Layer na haɗin ciki na layin.
II.bambanci tsakanin allon HDI da PCB na yau da kullun
Ana kera allon HDI gabaɗaya ta amfani da hanyar tarawa, ƙarin yadudduka, mafi girman ƙimar fasaha na hukumar.Kwamitin HDI na yau da kullun shine ainihin lokacin 1, HDI mai girma ta amfani da fasahar lamination sau 2 ko fiye, yayin amfani da ramukan da aka tattara, ramukan cika ramuka, bugun laser kai tsaye da sauran fasahar PCB masu ci gaba.Lokacin da yawa na PCB ya ƙaru fiye da allon Layer takwas, farashin masana'anta tare da HDI zai kasance ƙasa da tsarin hadaddun latsa-daidaitacce na gargajiya.
Ayyukan lantarki da daidaitattun sigina na allon HDI sun fi PCBs na gargajiya.Bugu da kari, allon HDI suna da ingantacciyar cigaba ga RFI, EMI, SPMICT FASAHA (Haɗin HDI) na iya yin ƙimar ƙirar samfurin, yayin haɗuwa da manyan ka'idodin aikin lantarki da ƙarfin aiki.
III.HDI allon kayan
Kayan HDI PCB sun gabatar da wasu sabbin buƙatu, gami da ingantacciyar kwanciyar hankali mai girma, motsi mai karewa da mara mannewa.kayan yau da kullun na HDI PCB shine RCC (tagulla mai rufin guduro).akwai nau'ikan RCC guda uku, wato polyimide metalized film, pure polyimide film, da kuma jefa polyimide film.
Fa'idodin RCC sun haɗa da: ƙaramin kauri, nauyi mai haske, sassauci da walƙiya, rashin daidaituwar halayen halayen da ingantaccen yanayin girma.A cikin aiwatar da HDI multilayer PCB, maimakon takardar haɗin gwiwa na gargajiya da foil na jan karfe a matsayin matsakaicin insulating kuma mai ɗaukar nauyi, RCC na iya dannewa ta hanyar dabarun murkushewa na al'ada tare da kwakwalwan kwamfuta.sannan ana amfani da hanyoyin hakowa da ba na injina ba kamar Laser don samar da haɗin gwiwar ƙananan ramuka.
RCC tana tafiyar da abubuwan da suka faru da haɓaka samfuran PCB daga SMT (Tsarin Dutsen Fasaha) zuwa CSP (Cip Level Packaging), daga hakowa na injiniya zuwa hakowar Laser, kuma yana haɓaka haɓakawa da ci gaba na microvia PCB, waɗanda duk sun zama manyan kayan PCB HDI. ku RCC.
A cikin ainihin PCB a cikin tsarin masana'antu, don zaɓin RCC, yawanci ana samun FR-4 misali Tg 140C, FR-4 high Tg 170C da FR-4 da Rogers hade laminate, waɗanda galibi ana amfani da su a zamanin yau.Tare da haɓaka fasahar HDI, kayan aikin HDI PCB dole ne su cika ƙarin buƙatu, don haka manyan abubuwan da ke faruwa na kayan PCB HDI ya kamata su kasance.

IV.aikace-aikacen fasahar masana'anta HDI
Wahalhalun masana'antar HDI PCB micro ta hanyar masana'anta, ta hanyar ƙarfe da layuka masu kyau.
1. Micro-ta hanyar-rami masana'antu
Kera-rami-rami ya kasance babbar matsalar masana'antar HDI PCB.Akwai manyan hanyoyin hakowa guda biyu.
a.Don hako ramuka na gama-gari, hakowa na inji koyaushe shine mafi kyawun zaɓi don babban inganci da ƙarancin farashi.Tare da haɓaka ƙarfin injin injina, aikace-aikacen sa a cikin ƙaramin rami kuma yana haɓakawa.
b.Akwai nau'i biyu na hakowa Laser: photothermal ablation da photochemical ablation.Na farko yana nufin tsarin dumama kayan aiki don narkar da shi da kuma fitar da shi ta hanyar rami da aka kafa bayan babban makamashi na Laser.Na karshen yana nufin sakamakon photons masu ƙarfi a cikin yankin UV da tsayin laser wanda ya wuce 400 nm.
Akwai nau'ikan nau'ikan Laser iri uku da ake amfani da su don sassauƙa da tsattsauran ra'ayi, wato excimer Laser, UV Laser hakowa, da CO 2 Laser.Fasahar Laser ba kawai ta dace da hakowa ba, har ma don yankewa da kafawa.Ko da wasu masana'antun suna kera HDI ta Laser, kuma kodayake kayan aikin hakowa Laser suna da tsada, suna ba da daidaito mafi girma, ingantaccen tsari da ingantaccen fasaha.Fa'idodin fasahar Laser sun sa ya zama hanyar da aka fi amfani da ita a masana'antar makafi/binne ta hanyar rami.A yau, kashi 99% na ramukan microvia HDI ana samun su ta hanyar hakowa ta Laser.
2. Ta hanyar ƙarfe
Babban wahala a cikin aikin ƙarfe ta hanyar rami shine wahalar cimma yumɓu mai yumɓu.Don zurfin rami plating fasaha na micro-ta ramukan, ban da yin amfani da plating bayani tare da high watsawa ikon, da plating bayani a kan plating na'urar ya kamata a kyautata a cikin lokaci, wanda za a iya yi da karfi inji stirring ko vibration, ultrasonic stirring, da kuma a kwance feshi.Bugu da ƙari, dole ne a ƙara yawan zafi na bangon rami kafin a saka.
Bugu da ƙari, haɓaka haɓakawa, hanyoyin haɓaka haɓaka ta hanyar HDI sun ga ci gaba a cikin manyan fasahohi: fasahar plating ɗin sinadarai, fasahar plating kai tsaye, da sauransu.
3. Layi Mai Kyau
Aiwatar da layi mai kyau ya haɗa da canja wurin hoto na al'ada da kuma hoton laser kai tsaye.Canja wurin hoto na al'ada tsari iri ɗaya ne da sinadari na yau da kullun don samar da layi.
Don hotunan kai tsaye na Laser, ba a buƙatar fim ɗin hoto, kuma an kafa hoton kai tsaye akan fim ɗin mai ɗaukar hoto ta hanyar laser.Ana amfani da hasken wutar lantarki na UV don aiki, yana ba da damar samar da mafita na ruwa don biyan bukatun babban ƙuduri da aiki mai sauƙi.Ba a buƙatar fim ɗin daukar hoto don kauce wa tasirin da ba a so ba saboda lalacewar fim, ba da damar haɗin kai tsaye zuwa CAD / CAM da kuma rage girman ƙirar masana'anta, yana sa ya dace da ƙayyadaddun ayyuka da yawa.
