Kodi mungakonze bwanji mbiri ya reflow?

Malinga ndi malingaliro a IPC association, generic Pb-freereflow ya soldermbiri ikuwonetsedwa pansipa.Dera la GREEN ndilosiyana lovomerezeka la ndondomeko yonse yobwereza.Kodi zikutanthauza kuti malo aliwonse m'dera la GREEN akuyenera kukwanira pulogalamu yanu yobwezeretsanso?Yankho mwamtheradi AYI!

Kutha kwa matenthedwe a PCB ndi kosiyana malinga ndi mtundu wa zinthu, makulidwe, kulemera kwa mkuwa komanso mawonekedwe a bolodi.Zimakhalanso zosiyana kwambiri pamene zigawozo zimayamwa kutentha kuti zitenthe.Zigawo zazikuluzikulu zingafunike nthawi yochulukirapo kuti ziwotche kuposa zazing'ono.Chifukwa chake, muyenera kusanthula bolodi lanu kaye musanapange mbiri ya reflow yapadera.

1. Pangani mbiri yobwereza.

Mbiri ya reflow yokhazikika imakhazikitsidwa pamalingaliro a soldering, mbiri ya solder yovomerezeka kuchokera kwa wopanga phala, kukula, makulidwe, kulemera kwa cooper, zigawo za bolodi ndi kukula, ndi kachulukidwe kazinthuzo.

1. Bweretsaninso bolodi ndikuyesa mbiri yeniyeni yotentha nthawi imodzi.
2. Onani mtundu wa solder, PCB ndi mawonekedwe agawo.
3. Kuwotcha-mu bolodi yoyesera yokhala ndi kugwedezeka kwamafuta komanso kugwedezeka kwamakina kuti muwone ngati bolodi ili yodalirika.
4. Fananizani zenizeni zenizeni zenizeni ndi mbiri yeniyeni.
5. Sinthani makhazikitsidwe a parameter ndikuyesa kangapo kuti mupeze malire apamwamba ndi mzere wanthawi yeniyeni ya reflow profile.
6. Sungani ma parameter okongoletsedwa malinga ndi zomwe gulu lomwe mukufuna likufuna.
