Umngxunya oqhubayo nge-Hole ukwabizwa ngokuba yi-HoLE. Ukuze kufezekiswe iimfuno zabathengi, ibhodi yesekethe nge-Hole kufuneka ixoke. Emva kokuziqhelanisa nokuziqhelanisa, i-Alumuminium ye-Alumnum ye-Alumnum itshintshiwe, kwaye iBhodi yeBhodi yeSiphathensi yeBhodi kunye nePlagging igqityiwe nge-mesh emhlophe. umngxunya. Ukuveliswa ngokuzinzileyo kunye nomgangatho othembekileyo.
Via umngxunya udlala indima yokuqhagamshelwa kunye nokunyanzelwa kwemigca. Ukuphuhliswa kwemveliso ye-elektroniki kukwakhuthaza ukuphuculwa kwe-PCB, kwaye ubeka phambili iimfuno eziphezulu kwi-PHEARD YOKUFUNDA I-BHODI YENKQUBO YOKUFUNDA NOKUGQIBELA. Via yeTekhnoloji ye-Hougging yafumana, kwaye kufuneka ifezekise ezi mfuno zilandelayo:

Ngophuhliso lweemveliso ze-elektroniki kwicala "lokukhanya, elincinci, elincinci kwaye lincinci", i-PCBS iphinde yaqulunqa kubunzima obuphezulu kunye nobunzima obuphezulu. Ke ngoko, inani elikhulu le-SMT kunye ne-BGA PCBS livele, kwaye abathengi bafuna ukubambisa xa amacandelo okunyusa, ikakhulu kubandakanya imisebenzi emihlanu:
. Ingakumbi xa sibeka i-vied hole kwi-BGA PAD, kufuneka kuqala senze umngxunya weplagi kwaye emva koko ifakwe igolide ukulungiselela ukuququzelelwa kwe-BGA.
(2) Kulumkele intsalela ye-flux kwi-Vieas;

Ukufezekiswa kwenkqubo yokuqhuba ye-hole
NgeeBhodi zeNtaba yeNtaba yeMpuma, ngakumbi ukunyusa i-BGA kunye ne-IC, iPlag ye-Vieg kufuneka ibe liflethi, i-Convex kunye ne-Concave Plus okanye thabatha i-1mil, kwaye kufuneka kungabikho dolophana elibomvu; I-Vie Hole ifihla ibhola ye-tin, ukwenzela ukufikelela kubathengi ngokweemfuno, i-wie ye-wine hole yenkqubo inokuchazwa, kwaye i-oyile kunzima ukuyila ngexesha lovavanyo lomoya oshushu kunye novavanyo lweoyile eluhlaza. Iingxaki ezifana nokuqhushumba kweoyile emva konyango. Ngokweyona meko yemveliso, iinkqubo ezahlukeneyo ze-pcb zishwankathelwe, kwaye ezinye ukuthelekisa kunye neenkcazo zenziwe kwinkqubo kunye nezibonelelo kunye nezinto ezingalunganga:
QAPHELA: Umgaqo wokuSebenza wokuSebenzisa umgangatho womoya oshushu kukusebenzisa umoya oshushu ukususa umthengisi ogqithisileyo ukusuka kumphezulu kunye nemingxunya yeBhodi yeSiphaluka eprintiweyo. Umthengisi osele udibene ngokulinganayo kwiipads, imigca yejoni engazihlukweni kunye neendawo zokupakisha umphezulu, eyindlela yonyango lomhlaba oshicilelweyo.
I-1. Inkqubo ye-clgging emva kwenqanaba lomoya elishushu
Ukuhamba kwenkqubo: Inkqubo engeyiyo iplagi yamkelwe ukuze imveliso. Emva kokuba umoya oshushu ugqityiwe, iscreen se-aluminium okanye isikrini se-inki sisetyenziselwa ukugcwalisa i-Pole ye-Hole efunekayo ngabathengi kuzo zonke iinqaba. I-inki ye-inki ingayinto ye-inki ye-inki okanye i-inki yetheko. Ngaphantsi kwemeko apho umbala wefilimu omanzi uyahambelana, i-inki ye-inki ilungele ukusebenzisa i-inki enye njengebhodi. Le nkqubo inokuqinisekisa ukuba imingxunya ayiyi kuphulukana ne-oyile emva kokuba umoya oshushu ugqityiwe, kodwa kulula ukubangela i-inki yomngxunya yeplagi kwaye ingalingani. Abathengi bathambekele ekuthengisweni kobuxoki (ngakumbi kwi-BGA) ngexesha lokunyuka. Abathengi abaninzi abayamkeli le ndlela.
2. Inqanaba lomoya elishushu kunye netekhnoloji ye-plug hole
2.1 Sebenzisa iphepha lealuminium ukuba liplagi umngxunya, qinisa, kwaye ipolise iBhodi yoThengiso lwegraphic
Le nkqubo isebenzisa umatshini wokuqhuba kwamanani ukuze ikhuphe iphepha lealuminium ekufuneka icwangciswe ukwenza isikrini, kwaye iqhube umngxunya ukuqinisekisa ukuba i-vie yomngxunya igcwele. I-inki yomngxunya ye-plug inokusetyenziswa nge-inki yokutsala, kwaye iimpawu zayo kufuneka zomelele. , I-shrinkage ye-resin incinci, kwaye i-birgy amandla odonga lomngxunya ilungile. Ukuhamba kwenkqubo: Ukunyanga kwangaphambili
Le ndlela inokuqinisekisa ukuba umngxunya weplagi ye-vale ye-vale iflethi, kwaye akuyi kubakho iingxaki ezisemgangathweni ezinjengokuqhushumba kweoyile kunye ne-oyile kumqolo womngxunya xa unomgangatho oshushu. Nangona kunjalo, le nkqubo ifuna ukuthathwa kwexesha elinye kobhedu ukwenza ubukhulu becala udonga lomngxunya bahlangabezana nomgangatho womthengi. Ke ngoko, iimfuno zokubekwa kobhedu kwiplate yonke ziphezulu kakhulu, kwaye ukwenziwa komatshini wokugaya iplagi kuphezulu kakhulu, ukuqinisekisa ukuba indawo ephantsi kobhedu icocekile kwaye ayicocekanga. Iifektri ezininzi ze-PCB azinalo inkqubo yobhedu eyodwa, kwaye ukusebenza kwezixhobo azifikeleli iimfuno, okukhokelela ekungasebenzi kakhulu kule nkqubo kwiifektri ze-PCB.
