Main chigawo Ntchito Kufotokoza
1. Muziona infuraredi china chotulutsa luso limene palokha kufufuza.
2. Gwiritsani infuraredi kutentha, n'zosavuta kudula kupyolera, kutentha chiwerengero kuboola mwambo china chotulutsa makina ndi sirocco.
3. Chosavuta operate.Just amafunika tsiku training.Can ntchito makina.
4. Palibe china chotulutsa zipangizo, zikhoza china chotulutsa zonse zikuluzikulu za 15x15-25x25mm.
5. makina uyu ali 650W Kutentha system.widely kuti 80x120mm.
6. infuraredi Kutentha palibe ndi sirocco otaya. Musati zimakhudzira wozungulira yaing'ono component.Can oyenera onse a chigawo, makamaka yaying'ono BGA chigawo.

1.Boot.
① Chongani mphamvu zoyendetsera, mphepo pulagi.
② Yatsani ntchito mphamvu source.Don't mpaka chikudutsa check.Pand adzasonyeza enactment value.When nthawi yotsiriza ntchito.
③ unsembe kukonza shell.Fix mzere pa mzere wa rack.Screw kuwala dongosolo height.Keep 20-30mm pakati pa makina kuwala ndi owotcherera.
④ Malinga ndi muyeso wa owotcherera piece.Proprictily wononga temperature.from60 ℃ -350 ℃ .When inu amavula 15 × 15mm piece.Choice kutentha 240-300 ℃ .When inu amavula 25 × 25mm piece.Choice kutentha 300-350 ℃ .The kutentha kubwera mpaka 350 ℃ dongosolo .The kuwala adzakwera tcheru straightly.Please malipiro zambiri wekha kulamulira time.avoid kuwotcha kunja.
⑤ kagwere focus.The kuwala dongosolo zing'onozing'ono m'mimba mwake ndi 15mm .the lalikulu ndi 30mm.Normally asamangodzifunira 20-30mm.
⑥ Yatsani mbale awiri switches.They ulamuliro zochangamutsa ndi dongosolo kuwala.
2.Dismantle ndi china chotulutsa.
① zonse kutentha, kupanga Chip kwambiri.
② Pambuyo oyenera nthawi, malata ndi kutsamba ndi kusungunuka, tulutsani Chip lapansi.
3.Weld Chip lapansi.
① kuyeretsa PAD.
② wokutira thandizo solder kamwazi (sayenera wandiweyani nawonso ali woyamba kwambiri wochepa thupi) ndi soldering malata mpira.
③ Dikirani kuthandiza solder kamwazi kuti volatilize mu kamwazi, kutentha ndi kwathunthu kusungunula ku mpira malata, malo molondola ndi kopanira, ndi cholinga pa Chip kuti china chotulutsa mu malo.
④ 936 searing-iron.Open ndi swich ndi enactment kutentha.
Chenjezo
1. ntchito, kumanga mphamvu yomweyo, onetsetsani thupi kuwala yozizira pansi, ndi kuziyika izo mu ngozi. Pambuyo kuzimitsa lophimba mphamvu;
2. Khalani njira kuwomba popanda angaletsedwe, thupi kuwala woyera;
3. Thandizo mu nthawi yabwino ndi wopukutidwa ndi mafuta kutsogolera positi, cholinga;
4. kusagwirizana pulagi pamene mulibe ntchito kwa nthawi yaitali;
5. Umagwira mosamala, chisamaliro kudzachitika.
