Menene Taron BGA?
Haɗa BGA yana nufin tsarin ɗora Ball Grid Array (BGA) akan PCB ta amfani da dabarar sake haɗawa. BGA wani abu ne da aka ɗora a saman wanda ke amfani da jerin ƙwallan solder don haɗa wutar lantarki. Yayin da allon da'ira ke wucewa ta cikin tanda mai sake haɗawa da solder, waɗannan ƙwallan solder suna narkewa, suna samar da haɗin lantarki.

Matakan Taro na BGA
Tsarin haɗa BGA yawanci ya ƙunshi matakai masu zuwa:
Shiri na PCB: Ana shirya PCB ta hanyar shafa man shafawa a kan faifan da za a saka BGA. Man shafawar man shafawa cakuda ne na barbashi da kuma kwararar ruwa, wanda ke taimakawa wajen yin amfani da man shafawa.
Sanya BGAs: Ana sanya BGAs, waɗanda suka ƙunshi guntuwar da'ira mai haɗe da ƙwallan solder a ƙasa, a kan PCB ɗin da aka shirya. Ana yin wannan yawanci ta amfani da injinan ɗauka da sanyawa ta atomatik ko wasu kayan haɗawa.

Sanyaya da Dubawa: Bayan an sake yin amfani da na'urar sake yin amfani da na'urar, ana sanyaya PCB ɗin don ƙarfafa haɗin gwiwar na'urar. Sannan ana duba shi don ganin ko akwai wata matsala, kamar rashin daidaito, gajeren wando, ko haɗin da aka buɗe. Ana iya amfani da duba na'urar ta atomatik (AOI) ko duba X-ray don wannan dalili.
Tsarin Aiki Na Biyu: Dangane da takamaiman buƙatun, ana iya yin ƙarin matakai kamar tsaftacewa, gwaji, da kuma rufin da aka haɗa bayan haɗa BGA don tabbatar da inganci da amincin samfurin da aka gama.

1. Ƙaramin sawun ƙafa
Marufin BGA ya ƙunshi guntu, haɗin gwiwa, siririn substrate, da murfin rufewa. Akwai ƙananan abubuwan da aka fallasa kuma kunshin yana da ƙarancin adadin fil. Tsawon guntu gaba ɗaya akan PCB na iya zama ƙasa da milimita 1.2.
2. Ƙarfi
Marufin BGA yana da ƙarfi sosai. Ba kamar QFP mai ƙarfin mil 20 ba, BGA ba ta da fil waɗanda za su iya lanƙwasa ko karyewa. Gabaɗaya, cire BGA yana buƙatar amfani da tashar sake fasalin BGA a yanayin zafi mai yawa.
3. Ƙananan ƙwayoyin cuta masu haifar da kumburi da ƙarfin aiki
Tare da gajerun fil da ƙarancin tsayin haɗuwa, marufin BGA yana nuna ƙarancin inductance da capacitance na ƙwayoyin cuta, wanda ke haifar da kyakkyawan aikin lantarki.
4. Ƙarin sararin ajiya
Idan aka kwatanta da sauran nau'ikan marufi, marufin BGA yana da kashi ɗaya bisa uku kawai na girman kuma kusan sau 1.2 na yankin guntu. Kayan ƙwaƙwalwa da na aiki ta amfani da marufin BGA na iya cimma fiye da ninki 2.1 na ƙarfin ajiya da saurin aiki.
