Uyini umehluko phakathi kwe-HDI PCB ne-PCB ejwayelekile?

Uma kuqhathaniswa namabhodi wesekethe ajwayelekile, amabhodi wesifunda we-HDI anomehluko nezinzuzo ezilandelayo:

1.Ubukhulu nesisindo

Ibhodi le-HDI: Lincane futhi lilula. Ngenxa yokusetshenziswa kwezintambo eziminyene kakhulu kanye nesikhala somugqa omncane wobubanzi bomugqa, amabhodi e-HDI angafinyelela umklamo ohlangene kakhudlwana.

Ibhodi lesifunda elivamile: ngokuvamile likhudlwana futhi liyasinda, lilungele izidingo zezintambo ezilula neziphansi.

2.Impahla kanye nesakhiwo

Ibhodi lesifunda le-HDI: Ngokuvamile lisebenzisa amaphaneli akabili njengebhodi eliwumgogodla, bese lakha isakhiwo esinezingqimba eziningi ngokusebenzisa i-lamination eqhubekayo, eyaziwa ngokuthi “BUM” yokunqwabelana kwezingqimba eziningi (ubuchwepheshe bokupakisha besifunda). Ukuxhumana kukagesi phakathi kwezingqimba kufinyelelwa ngokusebenzisa izimbobo eziningi ezincane ezingaboni nezimbobo.

Ibhodi lesifunda elivamile: Isakhiwo sendabuko se-multi-layer ngokuyinhloko ukuxhumana kwe-inter-layer ngokusebenzisa imbobo, futhi imbobo eyimpumputhe engcwatshwe ingasetshenziswa futhi ukufeza uxhumano lukagesi phakathi kwezingqimba, kodwa inqubo yokuklama kanye nokukhiqiza ilula, i-aperture. inkulu, futhi ukuminyana kwezintambo kuphansi, okufanelekela izidingo zohlelo lokusebenza zokuminyana okuphansi kuya kokuphakathi.

3.Inqubo yokukhiqiza

Ibhodi lesifunda le-HDI: Ukusetshenziswa kobuchwepheshe be-laser drilling direct, kungafinyelela ukuvuleka okuncane kwemigodi eyimpumputhe nemigodi egqitshiwe, imbobo engaphansi kuka-150um. Ngesikhathi esifanayo, izidingo zokulawula ukunemba kokuma kwembobo, izindleko nokusebenza kahle kokukhiqiza ziphezulu.

Ibhodi lesifunda elivamile: ukusetshenziswa okuyinhloko kobuchwepheshe bokugaya imishini, indawo yokuvula kanye nenani lezendlalelo ngokuvamile lilikhulu.

4.Ukuminyana kwezintambo

Ibhodi lesifunda le-HDI: Ukuminyana kwezintambo kuphakeme, ububanzi bomugqa kanye nebanga lomugqa ngokuvamile abukho ngaphezu kuka-76.2um, futhi ukuminyana kwendawo yokuxhumana yokushisela kungaphezu kuka-50 ngesentimitha yesikwele.

Ibhodi lesifunda elivamile: ukuminyana kwezintambo eziphansi, ububanzi bomugqa obanzi kanye nebanga lomugqa, ukuminyana kwephoyinti lokuxhumana le-welding eliphansi.

5. ukujiya kongqimba lwe-dielectric

Amabhodi e-HDI: Ugqinsi lwengqimba ye-dielectric mncane, ngokuvamile lungaphansi kuka-80um, futhi ukufana kogqinsi kuphakeme, ikakhulukazi kumabhodi aminyana kakhulu kanye nama-substrates apakishiwe anolawulo oluyimpande.

Ibhodi lesifunda elijwayelekile: ubukhulu bongqimba lwe-dielectric bukhulu, futhi izidingo zokufana kogqinsi ziphansi kakhulu.

6.Ukusebenza kukagesi

Ibhodi lesifunda le-HDI: linokusebenza kagesi okungcono, lingathuthukisa amandla esignali nokuthembeka, futhi libe nokuthuthuka okukhulu ekuphazamisekeni kwe-RF, ukuphazamiseka kwegagasi logesi, ukukhishwa kwe-electrostatic, ukuqhutshwa kwe-thermal nokunye.

Ibhodi lesifunda elivamile: ukusebenza kukagesi kuphansi, kulungele izinhlelo zokusebenza ezinezidingo eziphansi zokudlulisela isignali

7.Design ukuguquguquka

Ngenxa yedizayini yayo yokuminyana okuphezulu kwezintambo, amabhodi esekethe e-HDI angakwazi ukubona imiklamo yesekethe eyinkimbinkimbi endaweni elinganiselwe. Lokhu kunikeza abaklami ukuguquguquka okukhulu lapho beklama imikhiqizo, kanye nekhono lokukhulisa ukusebenza nokusebenza ngaphandle kokukhuphula usayizi.

Nakuba amabhodi wesifunda se-HDI anezinzuzo ezisobala ekusebenzeni nasekuklanyweni, inqubo yokukhiqiza iyinkimbinkimbi, futhi izidingo zemishini nobuchwepheshe ziphezulu. Isifunda se-Pullin sisebenzisa ubuchwepheshe obuphezulu obufana nokubhoboza i-laser, ukuqondanisa ukunemba kanye nokugcwaliswa kwembobo eyi-micro-blind, okuqinisekisa ikhwalithi ephezulu yebhodi le-HDI.

Uma kuqhathaniswa namabhodi esekethe ajwayelekile, amabhodi wesifunda we-HDI anomthamo wezintambo ophakeme, ukusebenza kangcono kukagesi nosayizi omncane, kodwa inqubo yawo yokukhiqiza iyinkimbinkimbi futhi izindleko ziphezulu. Ukuminyana kwezintambo sekukonke kanye nokusebenza kukagesi kwamabhodi esifunda anezingqimba eziningi awekho kahle njengamabhodi esekethe e-HDI, afanele izinhlelo zokusebenza zokuminyana okuphakathi nendawo neziphansi.
