Kugwiritsa ntchito
Pakadali pano, ukadaulo wa BGA wagwiritsidwa ntchito kwambiri pamakompyuta (makompyuta osunthika, makompyuta apamwamba, makompyuta ankhondo, makompyuta olankhulana), malo olumikizirana (mapeji, mafoni am'manja, ma modemu), gawo lamagalimoto (owongolera osiyanasiyana a injini zamagalimoto, zosangalatsa zamagalimoto) .Amagwiritsidwa ntchito pazida zosiyanasiyana zongoyenda, zomwe zofala kwambiri ndizosanja, ma network ndi zolumikizira.Ntchito zake zenizeni zikuphatikiza walkie-talkie, player, digito kamera ndi PDA, etc.
FAQs
BGAs (Mpira Grid Arrays) ndi zigawo za SMD zolumikizana pansi pa gawolo.Pini iliyonse imaperekedwa ndi mpira wa solder.Zolumikizira zonse zimagawidwa mu gridi yofananira pamwamba kapena matrix pagawo.
Ma board a BGA ali ndi zolumikizira zambiri kuposa ma PCB abwinobwino, kulola ma PCB ang'onoang'ono, ang'onoang'ono.Popeza zikhomo zili pansi pa bolodi, zotsogola zimakhala zazifupi, zomwe zimatulutsa ma conductivity abwino komanso ntchito yofulumira ya chipangizocho.
Zigawo za BGA zili ndi malo omwe azidzigwirizanitsa okha pamene solder imasungunuka ndikuwumitsa zomwe zimathandiza ndi kuyika kopanda ungwiro..chigawocho ndi usavutike mtima kulumikiza kutsogolera kwa PCB.Phiri lingagwiritsidwe ntchito kusunga malo a chigawocho ngati soldering ikuchitika ndi manja.
BGA phukusi kuperekakachulukidwe kakang'ono ka pini, kutsika kwamafuta, komanso kutsika kwamphamvukuposa mitundu ina ya paketi.Izi zikutanthawuza zikhomo zambiri zolumikizirana ndikuwonjezera magwiridwe antchito pa liwiro lalitali poyerekeza ndi mapaketi apawiri amzere kapena athyathyathya.BGA ilibe zovuta zake, komabe.
Ma BGA ICs ndizovuta kuziwona chifukwa cha zikhomo zobisika pansi pa phukusi kapena thupi la IC.Chifukwa chake kuyang'ana kowoneka sikutheka ndipo de-soldering ndizovuta.BGA IC solder ophatikizana ndi PCB pad amakonda kusinthasintha komanso kutopa komwe kumabwera chifukwa cha kutenthetsa panjira yowotcheranso.
Tsogolo la BGA Phukusi la PCB
Chifukwa chazifukwa zotsika mtengo komanso zolimba, phukusi la BGA lidzakhala lodziwika kwambiri pamsika wamagetsi ndi zamagetsi mtsogolomo.Komanso, pali zambiri zosiyanasiyana BGA phukusi mitundu anapangidwa kuti akwaniritse zofunika zosiyanasiyana mu mafakitale PCB, ndipo pali zambiri ubwino waukulu pogwiritsa ntchito luso limeneli, kotero ife tikhoza kuyembekezera tsogolo lowala pogwiritsa ntchito phukusi BGA, ngati muli ndi zofunika, chonde omasuka kulankhula nafe.
