The wamba mapangidwe vuto milandu kwa BGA mu PCB/PCBA

Nthawi zambiri timakumana osauka BGA soldering m'kati mwa ndondomeko PCB msonkhano chifukwa zosayenera PCB mapangidwe ntchito.Chifukwa chake, PCBFuture ipanga chidule ndi mawu oyambira kumilandu ingapo yodziwika bwino yamapangidwe ndipo ndikhulupilira kuti ikhoza kupereka malingaliro ofunikira kwa opanga PCB!

Pali makamaka zochitika izi:

1. The vias pansi BGA si kukonzedwa.

Pali kudzera mabowo BGA PAD, ndi mipira solder anataya ndi solder pa ndondomeko soldering;Kupanga kwa PCB sikukhazikitsa ndondomeko ya solder chigoba, ndipo kumayambitsa kutayika kwa solder ndi solder mipira kudzera mu vias moyandikana ndi pad, zomwe zimapangitsa kuti mipira ya solder isowa, monga momwe tawonetsera pa chithunzi chotsatira.

2.BGA solder chigoba sichinapangidwe bwino.

Kuyika kwa mabowo pa PCB pads kungayambitse kutayika kwa solder;The mkulu-kachulukidwe PCB msonkhano ayenera kutengera microvia, akhungu vias kapena plugging njira kupewa solder imfa;Monga momwe chithunzi chotsatirachi, chimagwiritsa ntchito soldering yoweyula, ndipo pali ma vias pansi pa BGA.Pambuyo yoweyula soldering, solder pa vias amakhudza kudalirika kwa BGA soldering, kuchititsa mavuto monga mabwalo lalifupi zigawo zikuluzikulu.

3. Mapangidwe a BGA pad.

Waya wotsogolera wa BGA pad sayenera kupitirira 50% ya m'mimba mwake ya pedi, ndipo waya wotsogolera wamagetsi opangira magetsi sayenera kukhala osachepera 0.1mm, ndiyeno nkuukulitsa.Pofuna kupewa mapindikidwe a pad, zenera la chigoba cha solder liyenera kukhala lalikulu kuposa 0.05mm, monga momwe chithunzichi chikusonyezera.

4.Kukula kwa PCB BGA PAd si standardized ndipo ndi lalikulu kwambiri kapena laling'ono kwambiri, monga momwe chithunzi pansipa.

5. Mapiritsi a BGA ali ndi kukula kosiyana, ndipo zogwirizanitsa zogulitsa zimakhala zozungulira zosawerengeka za kukula kwake, monga momwe tawonetsera mu chithunzi pansipa.

 6. Mtunda pakati pa BGA chimango mzere ndi m'mphepete mwa chigawo thupi ndi pafupi kwambiri.

Zigawo zonse za zigawozo ziyenera kukhala mkati mwazolemba zolembera, ndipo mtunda pakati pa mzere wa chimango ndi m'mphepete mwa phukusi la chigawocho uyenera kukhala woposa 1/2 wa kukula kwa solder kwa chigawocho, monga momwe tawonetsera pa chithunzi pansipa.

PCBFuture ndi akatswiri PCB & PCB msonkhano wopanga amene angapereke ndi PCB kupanga, PCB msonkhano ndi zigawo zikuluzikulu ntchito sourcing.Dongosolo labwino kwambiri lotsimikizira bwino komanso zida zosiyanasiyana zowunikira zimatithandiza kuyang'anira momwe ntchito yonse ikupangidwira, kutsimikizira kukhazikika kwa njirayi komanso mtundu wapamwamba wazinthu, panthawiyi, zida zapamwamba ndi njira zaukadaulo zakhazikitsidwa kuti zitheke.
