BGA Assembly ni iki?
Guteranya BGA bivuga inzira yo gushyira Ball Grid Array (BGA) kuri PCB hakoreshejwe uburyo bwo gusora busubiramo. BGA ni igice gishyirwa hejuru gikoresha ubwoko bw'imipira yo gusora kugira ngo ihuzwe n'amashanyarazi. Uko urubuga rwa circuit runyura mu itanura risubiramo ubushyuhe, iyi mipira yo gusora irashonga, igakora imikoranire y'amashanyarazi.
Ibisobanuro bya BGA
BGA: Urusobe rw'imipira
Ishyirwa mu byiciro rya BGA
PBGA: ipulasitiki ya BGA ipfundikiye ipulasitiki ya BGA
CBGA: BGA yo gupfunyika BGA ya keramik
CCGA: Inkingi ya keramik BGA inkingi ya keramik
BGA ipakiye mu buryo bugaragara
TBGA: kaseti BGA ifite inkingi y'umupira
Intambwe zo guteranya BGA
Uburyo bwo guteranya BGA busanzwe bugizwe n'intambwe zikurikira:
Gutegura PCB: PCB itegurwa hakoreshejwe uburyo bwo gusoda ku dupapuro aho BGA izashyirwa. Uburyo bwo gusoda ni uruvange rw'uduce tw'ibumba n'ingufu, bifasha mu gikorwa cyo gusoda.
Gushyira BGAs: BGAs, zigizwe na chip ya circuit integrated hamwe n'udupira two gusoda hasi, zishyirwa kuri PCB yateguwe. Ibi bikorwa hakoreshejwe imashini zikora zikoresha ikoranabuhanga cyangwa ibindi bikoresho byo guteranya.
Guhindura Umunyururu: PCB yakusanyijwe hamwe na BGA zashyizwemo inyuzwa mu itanura risubiramo. Ifuru isubiramo ishyushya PCB ku bushyuhe bwihariye bushongesha ifuru ishongesha, bigatuma udupira twa BGA twongera kugenda kandi tugahuza amashanyarazi na PCB pads.
Gukonjesha no Kugenzura: Nyuma yo kongera gukoresha solder, PCB irakonjeshwa kugira ngo ikomeze ingingo z'isolder. Hanyuma irasuzumwa niba hari inenge, nko kutagira umurongo ugororotse, amakabutura magufi, cyangwa aho ifunguye. Igenzura ryikora ry’amatwi (AOI) cyangwa igenzura rya X-ray rishobora gukoreshwa muri urwo rwego.
Uburyo bwa kabiri: Bitewe n'ibisabwa byihariye, hashobora gukorwa izindi gahunda nko gusukura, gupima no gusiga irangi nyuma yo guteranya BGA kugira ngo harebwe ko ibicuruzwa byarangiye ari inyangamugayo kandi bifite ireme.

1. Ikirenge gito
Paki ya BGA igizwe na chip, imiyoboro ihuza, substrate nto, n'igifuniko cyo gupfuka. Hari ibice bike bigaragara kandi paki ifite umubare muto w'udupira. Uburebure rusange bwa chip kuri PCB bushobora kuba milimetero 1.2.
2. Gukomera
Gupfunyika BGA birakomeye cyane. Bitandukanye na QFP ifite umuvuduko wa 20ml, BGA ntabwo ifite udupira dushobora gupfunyika cyangwa kuvunika. Muri rusange, gukuraho BGA bisaba gukoresha ikigo cyo kuvugurura BGA ku bushyuhe bwinshi.
3. Kugabanuka k'umuyoboro w'amazi n'ubushobozi bwo kuyakuramo
Hamwe n'udupira tugufi n'uburebure buke bwo guteranya, paki ya BGA igaragaza ubushobozi buke bwo gukwirakwiza ibiyobyabwenge n'ubushobozi buke, bigatuma amashanyarazi akora neza cyane.
4. Kongera umwanya wo kubika ibintu
Ugereranyije n'ubundi bwoko bw'ibipfunyika, ibipfunyika bya BGA bifite kimwe cya gatatu gusa cy'ingano n'inshuro zigera kuri 1.2 z'ubuso bwa chip. Ibikoresho byo kwibuka n'imikorere bikoresha ibipfunyika bya BGA bishobora kongera ubushobozi bwo kubika no kwihuta mu mikorere inshuro zirenga 2.1.
5. Gutuza cyane
Bitewe no kwaguka kw'udupira duto duturutse hagati muri chip mu ipaki ya BGA, inzira zo kohereza ibimenyetso bitandukanye ziragabanuka neza, bigabanya uburyo ibimenyetso bigabanuka kandi bikongera umuvuduko wo gusubiza no kurwanya ikibazo. Ibi byongera ituze ry'umusaruro.
6. Gukuraho ubushyuhe neza
BGA itanga ubushobozi bwiza bwo gukwirakwiza ubushyuhe, aho ubushyuhe bwa chip bwegera ubushyuhe bwo mu kirere mu gihe cyo gukora.
7. Byoroshye gukoreshwa mu gusubiramo
Udupira twa BGA dushyirwa hasi neza, bigatuma byoroha kubona aho byangiritse kugira ngo bivanweho. Ibi byoroshya ivugurura rya BGA.
8. Kwirinda akajagari k'insinga z'amashanyarazi
Gupakira BGA bituma habaho gushyira ibyuma byinshi by'amashanyarazi n'ibicanwa hagati, hamwe n'ibice bya I/O bishyirwa ku nkengero z'uruziga. Gutegura inzira mbere y'urugendo bishobora gukorwa kuri substrate ya BGA, hirindwa imiyoboro ya I/O idasobanutse neza.
Ubushobozi bwo guteranya RichPCBA BGA
RICHPCBA ni uruganda ruzwi ku isi mu gukora PCB no guteranya PCB. Serivisi yo guteranya BGA ni imwe muri serivisi nyinshi dutanga. PCBWay ishobora kuguha uburyo bwo guteranya BGA bwiza kandi buhendutse kuri PCB zawe. Ingufu ntoya zo guteranya BGA dushobora kwakira ni 0.25mm 0.3mm.
Nk'umutanga serivisi za PCB ufite uburambe bw'imyaka 20 mu gukora, gukora no guteranya PCB, RICHPCBA ifite ubumenyi bwinshi. Niba hari icyifuzo cyo guteranya BGA, twandikire!
