Iyo yakanaka reflux curve inofanirwa kunge iri tembiricha curve inokwanisa kuwana yakanaka welding yeakasiyana epamusoro peairi zvikamu paPCB board kuti isimbiswe, uye iyo solder joint haingove nekutaridzika kwakanaka asiwo kunaka kwemukati.Kuti uwane yakanaka inotungamira-isina reflow tembiricha curve, kune humwe hukama nemaitiro ese ekugadzira e lead-isina reflow.Pazasi, Chengyuan otomatiki ichataura nezve zvikonzero zvekusaita kutonhora kunopisa kana kunyorova kwe lead-isina reflow mavara.
Mukuita-lead-free reflow welding process, pane musiyano unokosha pakati pekupenya kwemutobvu-isina reflow solder majoini uye chiitiko chisina kujeka chinokonzerwa nekunyungudika kusina kukwana kwe solder paste.Kana bhodhi rakaputirwa ne solder paste richipfuura nemuchoto chekushisa kwakanyanya gasi, kana tembiricha yepamusoro yesolder paste isingasvikike kana kuti nguva yereflux haina kukwana, basa rekuyerera harizoburitswa, uye maokisi uye zvimwe zvinhu zviri pamusoro pe solder pad uye pini yechikamu haigone kucheneswa, zvichikonzera kunyorova kwakashata panguva ye lead-free reflow welding.
Kunyanya kukomba mamiriro ezvinhu ndeokuti nekuda kwekutadza kukwana set tembiricha, iyo welding tembiricha ye solder paste pamusoro peiyo redunhu bhodhi haigone kusvika kune tembiricha inofanirwa kuwanikwa kune iyo simbi solder mu solder paste kuti ipinde chikamu shanduko, iyo inotungamira kune inotonhora welding phenomenon pane inotungamira-isina reflow welding nzvimbo.Kana kuti nekuti tembiricha haina kukwana, kumwe kusara kunoyerera mukati me solder paste hakugone kuvhurika, uye kunonaya mukati mejoint ye solder kana yatonhodzwa, zvichikonzera kupenya kwakashata kwejoint ye solder.Kune rumwe rutivi, nekuda kwehurombo husina kunaka hweiyo solder paste pachayo, kunyangwe mamwe mamiriro akakodzera anogona kusangana nezvinodiwa tembiricha curve ye lead-free reflow welding, iyo mechanical properties uye chitarisiko chejoint solder mushure mekugadzira haigoni kusangana ne zvinodiwa zvewelding process.
