Intangiriro ku nyungu n'ibibi byaBga PCBikibaho
Umupira grid array (Bga) yacapwe inama yumuriro (PCB) ni umusozi wibice PCB yagenewe cyane cyane kumigabane ihuriweho. Ibibaho bya Bga bikoreshwa mubisabwa aho kwimuka hejuru bihoraho, kurugero, mubikoresho nka microprocers. Ibi ni bibi byacapwe imbaho kandi ntishobora gukoreshwa. BGA NEards ifite amakono ahuza kurusha PCB zisanzwe. Buri ngingo ku kibaho cya Bga irashobora gucuruza yigenga. Amasano yose yiyi PCB ikwirakwizwa muburyo bwa matrix imwe cyangwa grid. Izi PCB zateguwe kugirango urudoko rwose rushobora gukoreshwa byoroshye aho gukoresha gusa peripheri.
Amapine ya Bga Package ni ngufi cyane kuruta PCB isanzwe kuko ifite imiterere ya perimetero gusa. Kubera iyi mpamvu, itanga imikorere myiza kumuvuduko mwinshi. Bga gusudira bisaba kugenzura neza kandi akenshi iyobowe nimashini zikora. Niyo mpamvu ibikoresho bya BGA bidakwiriye kugenda.
Ikoranabuhanga rya BGA Gupakira
Ifuru yuzuye ikoreshwa kumugurisha ya Bga ku kibaho cyacapwe. Iyo gushonga imipira yumupira wamaguru bitangirira mu ifuni, impagarara hejuru yimipira yashongeshe bikomeza paki ihuza umwanya wacyo kuri PCB. Iyi mikorere irakomeza kugeza igihe paki ikuwe mu ifuro, ikonje kandi ikomera. Kugirango ugire amakuru yumurambo aramba, inzira igenzurwa na paki ya Bga irakenewe cyane kandi igomba kugera kubushyuhe bukenewe. Iyo tekinike yo kugurisha ikwiye ikoreshwa, irandura kandi ibishoboka byose byumuzunguruko mugufi.
Ibyiza bya Bga Gupakira
Hariho ibyiza byinshi byo kwa Bga, ariko ibyiza byo hejuru gusa birambuye hepfo.
1. Bga gupakira uburyo pcb Ibi bipaki bifasha kubika umwanya uhagije wo kwitondera muri PCB, bityo bigatuma imikorere yayo.
2. Kunoza imikorere y'amashanyarazi n'imisumari: Ingano ya Bga ni nto cyane, bityo iyics itandukanya ubushyuhe buke kandi inzira yo gutandukana biroroshye gushyira mubikorwa. Igihe cyose wafen washyizwe hejuru, ibyinshi mubushyuhe byimurwa kumurongo wumupira. Ariko, hamwe na silicon yapfuye yazamutse hepfo, silicon yapfuye ihuza hejuru ya paki. Niyo mpamvu bifatwa neza guhitamo tekinoroji yo gukonjesha. Nta pin imera cyangwa yoroshye muri pake ya Bga, bityo iramba ryibi pcbs iriyongereye mugihe nazo zemeza ko imirimo myiza y'amashanyarazi.
3. Kunoza inyungu zo gukora binyuze mubucuruzi buteye imbere: udupapuro twa Bga ni binini bihagije kugirango byoroshye kubagurisha kandi byoroshye gukora. Kubwibyo, koroshya gusudira no gutunganya bituma bihutira gukora. Ibipapuro binini byiyi PCB birashobora kandi gukoreshwa byoroshye niba bikenewe.
4. Gabanya ibyago byo kwangirika: Ipaki ya Bga ni ingenzi-leta zagasubitswe, bityo itanga iherezo ryinshi nubworohe muburyo bwose.
ya 5. Kugabanya ibiciro: ibyiza byavuzwe haruguru bifasha kugabanya ikiguzi cya Bga gupakira. Gukoresha neza ibibaho byacapweho bitanga amahirwe yo kubika amahirwe yo kuzigama ibikoresho no kunoza imikorere ya tranmoelectric, dufasha kwemeza ibikoresho bya elegitoroniki byo mu rwego rwo hejuru no kugabanya inenge.
Ibibi bya Bga Gupakira
Ibikurikira nibibi byibishushanyo bya Bga, byasobanuwe muburyo burambuye.
1. Uburyo bwo kugenzura buragoye cyane: biragoye cyane kugenzura umuzenguruko mugihe cyo kugurisha ibice kuri pake ya Bga. Biragoye cyane kugenzura amakosa azabaho muri pake. Nyuma ya buri gice gihagaze, paki iragoye gusoma no kugenzura. Nubwo ikosa ryabonetse mugihe cyo kugenzura, bizagora kubikosora. Kubwibyo, kugirango byorohereze ubugenzuzi, bihenze cyane scan na X-ray tekinoroji ikoreshwa.
2. Ibibazo Byirizwa: Amapaki ya Bga ashobora kwibasirwa no guhangayika. Ubu bugizi bwa nabi bugomba kunama. Iyi mihangayiko inyeganyega itera ibibazo byiringiro muri iyi mbaho zicapiro. Nubwo ibibazo byiringiro byingenzi muri pakisitani, birashoboka burigihe.
Bga yapakiye tekinoroji ya raypcb
Ikoranabuhanga rikoreshwa cyane rya BGA Ingano ya Bga ikoreshwa na Raypcb ni 0.3mm, nintera ntarengwa igomba kuba hagati yumuzunguruko ikomeza kuri 0.2mm. Umubare ntarengwa uri hagati ya paki ebyiri zitandukanye za Bga (niba zakomejwe kuri 0.2mm). Ariko, niba ibisabwa bitandukanye, nyamuneka hamagara Raypcb kugirango uhindure amakuru asabwa. Intera ya Bga Ingano yubunini bwerekanwe kumashusho hepfo.
Kazoza Bga
Ntabwo ahakana ko BGA Ibipfunyika bizayobora isoko ryamashanyarazi n'isoko rya elegitoroniki mugihe kizaza. Ejo hazaza h'apakira ya Bga birakomeye kandi bizaba ku isoko mugihe kitari gito. Ariko, igipimo kiriho kijyanye nikoranabuhanga ni cyihuta cyane, kandi biteganijwe ko mugihe cya vuba, hazabaho ubundi bwoko bwibice byumuzunguruko bikora neza kuruta gupakira ya Bga. Ariko, gutera imbere mu ikoranabuhanga na byo byazanye amafranga n'ibihe bihatira isi ya elegitoroniki. Kubwibyo, bifatwa ko BGA Packageng izagenda kure yinganda za elegitoroniki kubera ibikorwa byibiciro byimikorere nubuzima bwiza. Byongeye kandi, hari ubwoko bwinshi bwa bopage, kandi itandukaniro muburyo bwabo ryongera akamaro k'amapaki ya Bga. Kurugero, niba ubwoko bumwe bwa pakisitani budakwiriye kubicuruzwa bya elegitoroniki, ubundi bwoko bwa paki ya Bga izakoreshwa.
