Kuwongolera kutentha: Masiteshoni a BGA rework nthawi zambiri amakhala ndi machitidwe odziyimira pawokha amagetsi owongolera kutentha, omwe amatha kusintha kutentha kwa kutentha munthawi yeniyeni kupewa kuwonongeka kwa chip chifukwa cha kutentha kwambiri kapena kutsika.

Kusiyanasiyana kwa mfundo zogwirira ntchito zamitundu yosiyanasiyana ya BGA rework station

BGA rework siteshoni akhoza kugawidwa m'magulu awiri: kuwala mayalikidwe ndi sanali kuwala mayikidwe:

Kuyanjanitsa kwa Optical: Kuyanjanitsa kudzera mu makina owoneka bwino kumatsimikizira kulondola panthawi yowotcherera ndikuwongolera bwino.

Kuyanjanitsa kosawoneka bwino: Kuyanjanitsa kumachitika ndi masomphenya, mopanda kulondola kwenikweni

Njira yowotchera

Njira yowotchera ya BGA rework station nthawi zambiri imakhala magawo atatu otentha:

Mpweya wotentha wa pamwamba ndi pansi: Kutentha kudzera mu waya wotentha, ndikusamutsa mpweya wotentha kupita ku zigawo za BGA kudzera mumphuno ya mpweya kuti muteteze bolodi kuti lisasokonezedwe ndi kutentha kosiyana.

Kutentha kwapansi kwa infuraredi: makamaka kumagwira ntchito yotenthetsera, kumachotsa chinyezi mkati mwa bolodi lozungulira ndi BGA, ndikuchepetsa mwayi wopindika
