Momwe mungadziwire mtundu wa kuwotcherera kwa BGA, ndi zida ziti kapena njira zoyesera?Zotsatirazi kukuuzani za BGA kuwotcherera khalidwe anayendera njira pankhaniyi.
BGA kuwotcherera mosiyana capacitor-resistor kapena kunja pini kalasi IC, mukhoza kuona khalidwe kuwotcherera kunja.bga solder mu chowotcha pansipa, kudzera mu wandiweyani malata mpira ndi PCB bolodi malo.PambuyoZithunzi za SMTreflowuvunikapenawave solderingmakinaikamalizidwa, ikuwoneka ngati bwalo lakuda pa bolodi, lowoneka bwino, kotero ndizovuta kwambiri kuweruza ndi maso amaliseche ngati khalidwe la soldering lamkati likukwaniritsa zofunikira.
Ndiye ife tikhoza kokha ntchito akatswiri X-RAY kuti irradiate, kudzera X-RAY kuwala makina kudzera BGA pamwamba ndi PCB bolodi, pambuyo chithunzi ndi aligorivimu kaphatikizidwe, kudziwa ngati BGA kuwotcherera chopanda solder, solder zabodza, wosweka malata mpira ndi mavuto ena abwino.
Mfundo ya X-RAY
Mwa X-RAY kusesa cholakwika chamzere wamkati kuti apangitse mipira ya solder ndikupanga chithunzi cholakwika, ndiye kuti mipira ya solder ya BGA imasanjidwa kuti ipange chithunzi cholakwika.Chithunzi cha X-RAY chikhoza kufananizidwa molingana ndi deta yoyambirira ya CAD yojambula ndi magawo ogwiritsira ntchito, kotero kuti akhoza kutsimikizira ngati solder ali woyenerera kapena ayi panthawi yake.
