Masevhisi eMicro BGA PCB Assembly eHigh-Density Electronics

Kuungana kweMicro BGA PCB hakusi kungofanana nekugadzirwa kweBGA. Kana package ikashandisa tight ball arrangement, margin yekugadzira inokanganiswa nePCB footprint, pad geometry, solder-paste deposition, placement alignment, reflow behavior uye kugona kuongorora majoini akavanzwa pasi pepackage. Kune mutengi wekugadzira, mubvunzo unokosha ndewekuti fekitori yePCB assembly inogona here kudzora cheni iyoyo yese—kwete kungoti muchina wayo weSMT unogona kuisa chikamu chacho here.

Highleap Electronics ifekitari yekugadzira maPCB uye kugadzira maPCB . Kune mapurojekiti e-micro-BGA, maPCB nePCBA zvinogona kuitwa senzira imwe chete yekugadzira, kusanganisira kugadzira maPCB, kuwana zvikamu, kuunganidza maSMT, kuongorora uye kuyedzwa kwakabvumiranwa. Izvi zvinokosha kana micro-BGA iri pabhodhi rakakora, ichigovana kuunganidza nemamwe mapakeji eSMT, kana kuva chikamu chechirongwa cheprototype-to-production.

Zvinodiwa pakugadzira Micro-BGA PCB Assembly kuti pave nekugadzirwa kwakagadzirira kugadzirwa

Kuungana kwe micro-BGA kunofanirwa kuongororwa kubva papakeji kuenda kunze. Kudhirowa kwepakeji kunoratidza kurongeka kwebhora uye envelopu yemakanika, ukuwo dhizaini yePCB ichisarudza kuti array inobatanidza sei mune imwe circuit yese. Maitiro ekubatanidza anofanira kuburitsazve ma interfaces iwayo nguva dzose kuburikidza nekudhinda, kuisa uye kudzokorodza.

• Tsanangudzo yepakeji: Simbisa nhamba chaiyo yezvikamu zvemugadziri, dhizaini yepakeji, bhora rakamira, huwandu hwebhora, saizi yepakeji uye ruzivo rwekunongedzera.
• Maitiro epasi pePCB: Tarisa nhanho yaburitswa uchienzanisa nemagwaro echikamu uye maitiro ekugadzira akarongwa.
• Kutiza kweArray: Kufamba kwe micro-BGA kwakasimba kungada nzira yakasarudzwa zvakanaka kuburikidza ne fan-out. Mhinduro chaiyo inoenderana nepakeji uye chimiro chePCB pane kungoenderana neshoko rekuti "micro-BGA" chete.
• Zvinhu zvekuunganidza: Zvinodiwa zvestencil, solder paste, solder alloy uye reflow zvinofanirwa kuongororwa pamwe chete nehuwandu hwebhodhi nezvikamu.
• Inspection: Nekuti majoini emuchina ari pasi pepakeji, hurongwa hwekuongorora hunofanira kusanganisira nzira yakakodzera yemajoini akavanzwa.

Ndezvipi zvinhu zve micro-BGA zvinonyanya kukosha panguva yekuongorora makotesheni?

Pakuunganidzwa kwemutengo, ruzivo rwakanyanya kubatsira inhamba chaiyo yechikamu pamwe nedata rekugadzira PCB neBOM. Chirevo chakajairika chakadai sekuti "0.3 mm micro-BGA" hachitsananguri zvizere dambudziko rekugadzira. Mapakeji maviri ane pitch yakafanana anogona kuva nenhamba dzakasiyana dzemabhora, saizi yepakeji, tsoka uye zvinodiwa zvekuputika kwebhodhi.

Kuti uwane faira rePCB rakakwana , ipa mafaira ekugadzira neruzivo rwezvikamu zvinobvumira fekitori kuongorora dhizaini chaiyo pane kufungidzira kubva kumhuri yemazwi akakosha kana yemapakeji.

Kurongeka uye Kugadzirwa kweMicro-BGA PCB yeMabhodhi Akakura

Maitiro ekubatanidza haagone kutsiva nhanho yePCB isina kukodzera kana kuputika kusingashande. Saka mapurojekiti eMicro-BGA anobatsirwa nekubata kugadzirwa kwePCB nekubatanidza sebasa reinjiniya rakabatana. Izvi zvinonyanya kukosha kana array ichimanikidza nzira pfupi dzekubuda, kuchinja kwe dense layer kana nzvimbo diki dzakatenderedza package. Kana kuputika kwe micro-BGA kuchishandisa microvias kana via-in-pad, kugadzirwa kweHDI kwakabatana nekubatanidzwa kwezvikamu kunofanirwa kuongororwa usati waisa chando pattern yenyika uye nzira yekubatanidza.

Ongororo yePCB DFM inobatsira usati wagadzira nekuti timu yekugadzira inogona kuongorora data rePCB kuti ione kana paine zvirambidzo zvekugadzira uye zvekusanganisa zvirambidzo izvozvo zvisati zvava matambudziko emuchitoro.

Ko micro-BGA PCB inoda HDI nguva dzose here?

Kwete. Kudiwa kweHDI kunoenderana nepakeji, bhora, huwandu hwenzira yekufambisa, saizi yebhodhi, chimiro che layer uye nzira iripo yekubvisa. Micro-BGA inogona kukodzera pakuvaka kwakajairika kwe multilayer mune imwe dhizaini uye inoda maficha eHDI mune imwe. Nzira chaiyo ndeyekuongorora chaiyo pakeji uye zvinodiwa zvenzira yekufambisa pane kuita kuti HDI ive fungidziro yakajairika.

Kana dhizaini yakaburitswa ichida maficha ekubatanidza zvinhu zvine huwandu hwakawanda, nzira yekugadzira PCB inofanira kuongororwa pamwe chete nemaitiro ekubatanidza. Basa rekugadzira PCB reHighleap rinogona kuva chikamu chenzira iyoyo yekugadzira yakabatana.

Kudhinda, Kuisa uye Kudzoreredza Stencil yeMicro-BGA

Pakusangana kwe micro-BGA, mhedzisiro yekusungirirwa inokanganiswa zvakanyanya nezvinoitika chikamu chisati chapinda muovheni yekudzoserwa kwemvura. Kuvhurika kwestencil, mamiriro ekunamira uye dhipoziti yakadhindwa zvinoratidza huwandu hwekusungirirwa hunowanikwa panzvimbo yega yega. Kuiswa kwacho kunofanirwa kuenderana nePCB pads, nepo kudzoserwa kwemvura kuchifanira kugadzira kusungirirwa kwakafanana mubhodhi rese.

1. Ongorora stencil uchienzanisa netsoka chaiyo. Maitiro ekuvhara nekusarudzwa kwefoil zvinofanirwa kufungwa nezvazvo pamwe chete ne micro-BGA pad yakagadzirwa pamwe chete nezvimwe zvikamu zviri paPCB imwe chete.
2. Kudhinda ne solder-paste. Kuchinja-chinja kwekudhinda kunokosha nekuti kuisa mari mubhokisi kunogona kuva dambudziko rakavanzika mushure mekunge pasuru yaiswa.
