Ntchito zazikulu za BGA rework station ndikuchotsa ndendende tchipisi towonongeka, kukonza malo osokera, kugulitsanso tchipisi, kuyang'anira ndi kuwongolera, komanso kukonza bwino. Makamaka:

Kuchotsa molondola tchipisi tawonongeka: BGA rework station ikhoza kupereka kutentha kwa yunifolomu ndi kuwongolera kusungunula mipira ya solder kuzungulira chip, potero kukwaniritsa kuchotsedwa kosawononga kwa chip. Poyang'anira madera otentha ndi mbiri ya kutentha, rework station ikhoza kuonetsetsa kuti bolodi la dera kapena zigawo zina sizikuwonongeka panthawi yochotsa.

Konzani soldering pamwamba: Pambuyo kuchotsa chip, rework siteshoni ingathandize kuchotsa solder otsalira pa bolodi PCB ndi kupereka woyera ndi lathyathyathya pamwamba pa re-soldering. Gawo ili ndilofunika kuti mutsimikizire mtundu wa soldering wa chip chatsopano.

Re-soldering Chips: Malo ogwiritsira ntchito rework ali ndi dongosolo lokonzekera bwino kwambiri komanso malo otenthetsera, omwe amatha kuyika bwino chipangizo chatsopano cha BGA pamalo osankhidwa, kuonetsetsa kuti mipira yonse ya solder ikugwirizana bwino ndi mapepala oyenerera. Mwa kutenthetsa mofanana, malo opangira ntchito amatha kukwaniritsa zowonjezera zowonjezera zowonjezera, kupititsa patsogolo kulimba kwa ziwalo za solder, ndi kuchepetsa mwayi wa zokopa zabodza ndi zozizira zozizira.

Kuyang'anira ndi Kuwongolera: Malo opangira ma BGA apamwamba kwambiri amakhala ndi makina owunikira komanso zida zowunikira ma X-ray, zomwe zimatha kuyang'ana zowona ndikuzindikira chilema chamkati isanayambe komanso itatha kuwotcherera kuti zitsimikizire mtundu wa kuwotcherera.

Limbikitsani kukonza bwino: Masiteshoni amakono a BGA rework nthawi zambiri amathandizira gawo lina la ntchito yodzichitira kuti muchepetse kulowererapo pamanja ndikuwongolera kukonza bwino. Mawonekedwe anzeru amalola ogwiritsa ntchito kukhazikitsa magawo mosavuta ndikuwunika momwe zimakhalira, ndikuchepetsa luso laukadaulo.

Kufunika kwa BGA rework station pakukonza zida zamagetsi kumawonekera pazifukwa izi:

Sinthani kukonza bwino: BGA rework station imatha kumaliza mwachangu komanso molondola kukonza tchipisi ta BGA, ndikuwongolera kwambiri kukonza bwino.

Kuchepetsa mtengo wokonza : Pokonza tchipisi talephera m'malo mosintha bolodi lonse kapena chipangizo, BGA rework station imachepetsa mtengo wokonza.

Kukonzekera kotsimikizika: Kuwongolera kolondola kwa kutentha, mawonekedwe owoneka bwino ndi ntchito zowunikira zimatsimikizira kukhazikitsidwa ndi kugulitsa tchipisi ta BGA

Pankhani ya kuchuluka kwa ntchito, BGA rework station itha kugwiritsidwa ntchito osati pazida zing'onozing'ono zamagetsi monga mafoni am'manja, makompyuta apakompyuta, ndi laputopu, komanso zida zazikulu zamagetsi monga ma seva ndi zida zowongolera mafakitale, ndipo ili ndi zida zambiri chiyembekezo chogwiritsa ntchito.
