Chiyambi cha ntchito ya reflow uvuni

Reflowuvunindiye njira zamakono zamakono mu SMT, reflow soldering khalidwe ndiye chinsinsi chodalirika, zimakhudza mwachindunji kudalirika kwa ntchito ndi phindu lachuma la zipangizo zamagetsi, ndipo ubwino wa kuwotcherera umadalira njira yowotcherera yomwe imagwiritsidwa ntchito, zipangizo zowotcherera, teknoloji yowotcherera ndi kuwotcherera. zida.

Ndi chiyaniMakina osindikizira a SMT?

Reflow soldering ndi imodzi mwazinthu zitatu zazikulu pakuyika.Reflow soldering makamaka ntchito solder bolodi dera kuti wakhala wokwera zigawo zikuluzikulu, kudalira Kutentha kusungunula solder phala kupanga zigawo SMD ndi dera ziyangoyango maphatikizidwe kuwotcherera pamodzi, ndiyeno kudzera reflow soldering kuzirala kuziziritsa solder phala kuti. limbitsani zigawo ndi mapepala pamodzi.Koma ambiri a ife kumvetsa reflow soldering makina, ndiye, kudzera reflow soldering ndi PCB bolodi mbali kuwotcherera anamaliza makina, panopa ndi osiyanasiyana kwambiri ntchito, makamaka ambiri fakitale zamagetsi ntchito, kumvetsa reflow soldering, choyamba. kumvetsetsa ndondomeko ya SMT, ndithudi, mwa mawu a layman ndi kuwotcherera, koma kuwotcherera ndondomeko reflow soldering amaperekedwa ndi kutentha wololera, ndiko kuti, ng'anjo kutentha pamapindikira.

Udindo wa reflow uvuni

Reflow udindo ndi Chip zigawo anaika mu bolodi dera anatumiza mu chipinda reflow, pambuyo kutentha kwambiri ntchito solder Chip zigawo zikuluzikulu za solder phala kupyolera mu kutentha kutentha mpweya kupanga reflow kutentha kusintha ndondomeko kusungunuka, kotero kuti zigawo za chip ndi mapepala a bolodi ozungulira ophatikizidwa, ndiyeno utakhazikika pamodzi.

Mawonekedwe aukadaulo wa Reflow soldering

1. Zigawo zimatha kugwedezeka pang'ono, koma nthawi zina zimapatsa chipangizocho kupsinjika kwakukulu kwamafuta.

2. Pokhapokha mu zigawo zofunika za ntchito solder phala, angathe kulamulira kuchuluka kwa solder phala ntchito, angapewe m'badwo wa zolakwika monga mlatho.

3. Kuthamanga kwapamwamba kwa solder yosungunuka kungathe kukonza kupatuka kwakung'ono kwa malo oyikapo zigawozo.

4. Gwero la kutentha kwamaloko lingagwiritsidwe ntchito kuti njira zosiyanasiyana za soldering zigwiritsidwe ntchito pazitsulo zomwezo.

5. Zonyansa nthawi zambiri sizisakanizidwa mu solder.Mukamagwiritsa ntchito solder phala, mawonekedwe a solder amatha kusungidwa bwino.
