Intangiriro kubyiza nibibi byaBGA PCBikibaho

Umupira wumurongo wumurongo (BGA) wacapwe wumuzunguruko (PCB) nubuso bwububiko bwa PCB bwashizweho byumwihariko kumuzunguruko. Ikibaho cya BGA gikoreshwa mubikorwa aho kwishyiriraho hejuru bihoraho, kurugero, mubikoresho nka microprocessor. Ibi nibishobora gukoreshwa byanditseho imizunguruko kandi ntibishobora gukoreshwa. Ikibaho cya BGA gifite pin nyinshi zihuza kuruta PCB zisanzwe. Buri ngingo ku kibaho cya BGA irashobora kugurishwa mu bwigenge. Ihuza ryose ryizi PCBs ryakwirakwijwe muburyo bwa matrix imwe cyangwa gride yo hejuru. Izi PCB zakozwe kuburyo impande zose zishobora gukoreshwa byoroshye aho gukoresha gusa agace kegereye.

Amapaki ya pake ya BGA ni ngufi cyane kuruta PCB isanzwe kuko ifite imiterere ya perimeteri gusa. Kubera iyi mpamvu, itanga imikorere myiza kumuvuduko mwinshi. Gusudira BGA bisaba kugenzura neza kandi akenshi biyoborwa nimashini zikoresha. Niyo mpamvu ibikoresho bya BGA bidakwiriye gushyirwaho sock.

Kugurisha tekinoroji ya BGA gupakira

Ifuru yo kumurika ikoreshwa mugurisha paki ya BGA kumurongo wacapwe. Iyo gushonga kw'imipira yagurishijwe bitangiye imbere mu ziko, impagarara hejuru yimipira yashongeshejwe zituma paki ihuza umwanya wacyo kuri PCB. Iyi nzira irakomeza kugeza paki ikuwe mu ziko, ikonje kandi igakomera. Kugirango habeho kugurisha igihe kirekire kugurisha, inzira igurishwa yo kugurisha paki ya BGA irakenewe cyane kandi igomba kugera kubushyuhe bukenewe. Iyo hakoreshejwe uburyo bukwiye bwo kugurisha, binakuraho ibishoboka byose byumuzunguruko mugufi.

Ibyiza byo gupakira BGA

Hariho ibyiza byinshi byo gupakira BGA, ariko ibyiza byo hejuru gusa birambuye hepfo.

1. Gupakira BGA ikoresha umwanya wa PCB neza: Gukoresha ibipfunyika BGA biyobora ikoreshwa ryibintu bito hamwe nintambwe ntoya. Izi paki nazo zifasha kuzigama umwanya uhagije wo kwihitiramo muri PCB, bityo bikongerera imbaraga.

2. Kunoza imikorere yamashanyarazi nubushyuhe: Ingano yububiko bwa BGA ni nto cyane, kubwibyo PCBs ikwirakwiza ubushyuhe buke kandi inzira yo kuyisohora biroroshye kubishyira mubikorwa. Igihe cyose wafer ya silicon yashizwe hejuru, ubushyuhe bwinshi bwoherezwa kumurongo wumupira. Ariko, hamwe na silicon ipfa gushira hejuru, silicon ipfa ihuza hejuru yipaki. Iyi niyo mpamvu ifatwa nkuburyo bwiza bwo gukonjesha ikoranabuhanga. Hano nta pine igoramye cyangwa yoroshye muri pake ya BGA, bityo rero kuramba kwizi PCBs byiyongera mugihe kandi bitanga amashanyarazi meza.

3. Kunoza inyungu zinganda binyuze mugucuruza neza: Amapaki yamapaki ya BGA ni manini bihagije kugirango byoroshye kugurisha kandi byoroshye kuyakoresha. Kubwibyo, koroshya gusudira no gukora bituma byihuta cyane gukora. Amapaki manini yizi PCB arashobora kandi gukorwa byoroshye mugihe bikenewe.

4. Gabanya INGARUKA ZO KWangiza: Porogaramu ya BGA iragurishwa-ikomeye, bityo itanga igihe kirekire kandi iramba mubihe byose.

ya 5. Kugabanya ibiciro: Ibyiza byavuzwe haruguru bifasha kugabanya igiciro cyo gupakira BGA. Gukoresha neza imbaho ​​zicapye zitanga ubundi buryo bwo kuzigama ibikoresho no kunoza imikorere yumuriro wa elegitoronike, bifasha kwemeza ibikoresho bya elegitoroniki yo mu rwego rwo hejuru no kugabanya inenge.

Ibibi byo gupakira BGA

Ibikurikira nimwe mubibi byapaki ya BGA, byasobanuwe muburyo burambuye.

1. Igikorwa cyo kugenzura kiragoye cyane: Biragoye cyane kugenzura umuzenguruko mugihe cyo kugurisha ibice kuri pake ya BGA. Biragoye cyane kugenzura amakosa yose ashobora kuba muri pake ya BGA. Nyuma yuko buri kintu kigurishijwe, paki iragoye gusoma no kugenzura. Nubwo hari ikosa ryabonetse mugihe cyo kugenzura, bizagorana kubikosora. Kubwibyo, kugirango byoroherezwe ubugenzuzi, CT scan ihenze cyane hamwe na tekinoroji ya X-ray.

2. Ibibazo byo kwizerwa: BGA yamapaki arashobora guhangayika. Uku gucika intege guterwa no kunama. Uku guhangayikishwa gutera ibibazo byokwizerwa muribi bibaho byacapwe. Nubwo ibibazo byokwizerwa bidasanzwe mubipaki bya BGA, ibishoboka burigihe.

BGA yapakiye tekinoroji ya RayPCB

Ikoranabuhanga rikoreshwa cyane kubunini bwa pake ya BGA ikoreshwa na RayPCB ni 0.3mm, kandi intera ntoya igomba kuba hagati yumuzunguruko ikomeza kuri 0.2mm. Umwanya muto hagati yububiko bubiri bwa BGA (niba bugumye kuri 0.2mm). Ariko, niba ibisabwa bitandukanye, nyamuneka hamagara RAYPCB kugirango uhindure ibisobanuro bikenewe. Intera yubunini bwa BGA irerekanwa mumashusho hepfo.

Ibizaza BGA

Ntawahakana ko gupakira BGA bizayobora isoko ry'amashanyarazi na elegitoroniki mugihe kizaza. Igihe kizaza cyo gupakira BGA kirakomeye kandi kizaba ku isoko igihe kitari gito. Nyamara, igipimo kiriho cyo gutera imbere mu ikoranabuhanga kirihuta cyane, kandi biteganijwe ko mu minsi ya vuba, hazaba hari ubundi bwoko bwikibaho cyacapishijwe imashini ikora neza kuruta gupakira BGA. Ariko, iterambere mu ikoranabuhanga ryazanye kandi ifaranga n’ibiciro ku isi ya elegitoroniki. Kubwibyo, hafatwa ko gupakira BGA bizagera kure muruganda rwa elegitoroniki bitewe nigiciro cyinshi nimpamvu ziramba. Mubyongeyeho, hari ubwoko bwinshi bwibikoresho bya BGA, kandi itandukaniro mubwoko bwabo byongera akamaro k'ibikoresho bya BGA. Kurugero, niba ubwoko bumwe bwibikoresho bya BGA bidakwiriye kubicuruzwa bya elegitoronike, ubundi bwoko bwa BGA buzakoreshwa.
