4 Ungqimba ENIG FR4 Ungcwatshwe Nge-PCB
Mayelana ne-HDI PCB
Ngenxa yethonya lethuluzi lokumba, izindleko zokumba kwe-PCB yendabuko ziphezulu kakhulu lapho ububanzi bokubhoboza bufinyelela ku-0.15mm, futhi kunzima ukuthuthuka futhi.Ukubhobolwa kwebhodi le-HDI PCB akusancikile emshinini ovamile wokumba, kodwa kusetshenziswa ubuchwepheshe bokubhola nge-laser.(ngakho ngezinye izikhathi ibizwa ngokuthi i-laser plate.) Ububanzi bembobo yokubhoboza yebhodi le-HDI PCB ngokuvamile bungu-3-5mil (0.076-0.127mm), futhi ububanzi bomugqa ngokuvamile bungu-3-4mil (0.076-0.10mm).Ubukhulu bephedi bungancishiswa kakhulu, ngakho-ke ukusatshalaliswa komugqa okwengeziwe kungatholakala endaweni yeyunithi, okuholela ekuxhumekeni kokuminyana okuphezulu.
Ukuvela kobuchwepheshe be-HDI kuzivumelanisa futhi kukhuthaze ukuthuthukiswa kwemboni ye-PCB.Ukuze i-BGA ne-QFP eminyene kakhulu ingahlelwa ngebhodi le-HDI PCB.Njengamanje, ubuchwepheshe be-HDI busetshenziswe kabanzi, lapho i-HDI ye-oda lokuqala isetshenziswe kabanzi ekukhiqizeni i-0.5 pitch BGA PCB.
Ukuthuthukiswa kobuchwepheshe be-HDI kukhuthaza ukuthuthukiswa kobuchwepheshe be-chip, obukhuthaza ukuthuthuka nokuthuthuka kobuchwepheshe be-HDI.
Njengamanje, i-chip ye-BGA engu-0.5pitch isetshenziswe kabanzi onjiniyela bokuklama, futhi i-engeli ye-solder ye-BGA iye yashintsha kancane kancane kusukela esimweni sokugoba isikhungo noma ukugxilisa maphakathi kuya ohlotsheni lwesignali emaphakathi nokuphumayo okudinga izintambo.
Izinzuzo Zezimpumputhe Ngokusebenzisa Futhi Ukungcwatshwa Nge-PCB
Ukusetshenziswa kwezimpumputhe nokungcwatshwa nge-PCB kunganciphisa kakhulu usayizi nekhwalithi ye-PCB, kunciphise inani lezendlalelo, kuthuthukise ukuhambisana kozibuthe kagesi, kukhuphule izici zemikhiqizo kagesi, kunciphise izindleko, futhi kwenze umklamo usebenze kalula futhi usheshe.Ekwakhiweni kwe-PCB yendabuko kanye nokwenza imishini, ngokusebenzisa imbobo kuzoletha izinkinga eziningi.Okokuqala, bathatha indawo enkulu esebenzayo.Okwesibili, inqwaba yezimbobo endaweni eyodwa iphinda ibangele isithiyo esikhulu emzileni wesendlalelo sangaphakathi se-PCB enezingqimba eziningi.Lezi zimbobo zithatha isikhala esidingekayo sokuhamba.Futhi ukubhola ngomshini okuvamile kuzoba umsebenzi ophindwe izikhathi ezingu-20 kunobuchwepheshe obungabhobozi.
