Zinthu zowongoka za njira yowotchera yopanda lead yopanda mafunde

Kuphatikiza njira zotsogola zamakhalidwe abwino ndi zoyeserera zachikhalidwe pakuwotchera kopanda lead kumachepetsa kusinthasintha kosafunikira, kumachepetsa kutayika kwa kupanga komanso kumapereka phindu lalikulu.Kuti mukwaniritse cholingacho m'njira yabwino kwambiri, pangani zinthu zonse momwe mungathere ndi kupatuka kochepa pakati pa zinthu.

Zinthu zowongoleredwa za njira ya soldering yopanda lead-free wave:

Kuti mupange kuyesa koyenera kwa ma wave soldering process, choyamba lembani vuto, cholinga ndi zomwe zikuyembekezeka kutulutsa ndi njira zoyezera.Kenako dziwani magawo onse azinthu ndikutanthauzira zofunikira zomwe zimakhudza zotsatira:

1. Zinthu zowongoka:

C1 = zinthu zomwe zimakhudza kwambiri ndondomekoyi ndipo zimatha kuyendetsedwa mwachindunji;
C2 = Chinthu chomwe chiyenera kuyimitsa ndondomekoyi ngati chinthu cha C1 chikusintha.

Pochita izi, zinthu zitatu za C1 zidasankhidwa:

B = nthawi yolumikizana
C = kutentha kwa preheat
D = kuchuluka kwa kusintha

2. Phokoso la phokoso ndilosiyana lomwe limakhudza kupatuka ndipo sizingatheke kapena zotsika mtengo kulamulira.Kusintha kwa kutentha kwa m'nyumba, chinyezi, fumbi, ndi zina zotero panthawi yopanga / kuyesa.Pazifukwa zomveka, chigawo cha phokoso sichinapangidwe muyeso.Cholinga chachikulu ndikuwunika momwe zinthu zimakhudzira khalidwe la munthu aliyense payekha.Kuyesera kowonjezera kuyenera kuchitidwa kuti ayese momwe angayankhire pokonza phokoso.

Kenako sankhani mawonekedwe omwe akuyenera kuyesedwa: kuchuluka kwa zikhomo popanda milatho ya solder ndi kuyenerera kwa kudzaza.Nthawi zambiri kafukufuku wanthawi imodzi amagwiritsidwa ntchito kuti adziwe zowongolera, koma kuyesaku kumagwiritsa ntchito L9 orthogonal array.M'mayesero asanu ndi anayi okha, magawo atatu azinthu zinayi adafufuzidwa.

Kukonzekera koyenera kudzapereka deta yodalirika kwambiri.Kusiyanasiyana kwa magawo owongolera kuyenera kukhala kopitilira muyeso kuti vutoli liwonekere;mu nkhani iyi, osauka malowedwe a solder milatho ndi vias.Kuti muyese zotsatira za mlatho, zikhomo zogulitsidwa popanda mlatho zinawerengedwa.Mphamvu pakulowa m'dzenje, dzenje lililonse lodzaza ndi solder limalembedwa momwe zasonyezedwera.Chiwerengero chonse cha mfundo pa bolodi ndi 4662.
