Iyo yekutungamirira-isina reflow soldering tembiricha yakakwira zvakanyanya kupfuura iyo lead-based reflow soldering tembiricha.Iyo tembiricha yekumisikidza ye lead-isina reflow soldering yakaoma zvakare kugadzirisa.Kunyanya nekuti iyo inotungamira-isina soldering reflow process hwindo idiki kwazvo, kutonga kweiyo lateral tembiricha musiyano wakakosha.Musiyano wakakura wetembiricha wepashure mukuyerera kwekutengesa kunokonzeresa kukanganisa kwebatch.Saka isu tingadzikise sei lateral tembiricha mutsauko mune reflow soldering kuti tiwane yakanakira lead-isina reflow soldering maitiro?Chengyuan otomatiki inotanga kubva pane zvinhu zvina zvinokanganisa reflow soldering maitiro.
1. Kutamisa mhepo inopisa mune lead-isina reflow soldering muchoto
Parizvino, iyo mainstream lead-isina reflow soldering inotora iyo yakazara inopisa mhepo yekudziya nzira.Mukugadzirisa kweiyo reflow soldering oveni, infrared heat yakabuda zvakare.Nekudaro, nekuda kwekudziya kwe infrared, iyo infrared absorption uye kuratidzira kweakasiyana mavara ezvikamu zvakasiyana uye nekuda kweyakatarisana yepakutanga Chishandiso chakavharwa uye chinoburitsa mumvuri mhedzisiro, uye ese ari maviri mamiriro anokonzeresa kusiyana kwekushisa uye kuisa lead soldering panjodzi yekusvetuka kunze. yewindo rekuita.Naizvozvo, infrared yekudziya tekinoroji yakabviswa zvishoma nezvishoma munzira yekudziya yereflow soldering oveni.Mukutengesa-isina-lead soldering, zvinodikanwa kuti utarise kune kupisa kupisa mhedzisiro, kunyanya kune yepakutanga zvishandiso zvine hombe kupisa simba.Kana kupisa kwakaringana kusingakwanise kuwanikwa, tembiricha yekukwira inokwira zvakanyanya kuseri kwemidziyo ine diki yekupisa simba, zvichikonzera kusiyana kwetembiricha.Kuenzaniswa nekushandisa yakazara mhepo inopisa inotungamira-isina reflow oveni, iyo lateral tembiricha musiyano we lead-isina reflow soldering ichaderedzwa.
2. Chain speed control yelead-free reflow oven
Lead-isina reflow soldering cheni yekumhanyisa kudzora inokanganisa lateral tembiricha musiyano wedunhu bhodhi.Kazhinji kutaura, kudzikisa kumhanya kweketani kunopa michina ine hombe yekupisa yakawanda nguva yekupisa, nekudaro ichidzikisa lateral tembiricha musiyano.Asi mushure mezvose, kugadzika kwechivharo chekushisa kwechoto kunoenderana nezvinodiwa zve solder paste, saka kuderedzwa kweketani kunonoka hakugoneki mukugadzirwa chaiko.Izvi zvinoenderana nekushandiswa kweiyo solder paste.Kana paine akawanda makuru ekupisa-absorbing zvikamu pane redunhu bhodhi, Kune zvikamu, zvinokurudzirwa kudzikisa reflow yekufambisa cheni kumhanya kuitira kuti hombe chip zvikamu zvikwanise kunyatsopisa kupisa.
3. Kudzora kwekumhanya kwemhepo uye vhoriyamu yemhepo mune lead-isina reflow oven
Kana iwe ukachengeta mamwe mamiriro muhovhoni isina-lead-free reflow isina kuchinjika uye uchingoderedza kukurumidza kwefan muhovhoni isina-lead reflow ne30%, tembiricha pabhodhi redunhu inodonha neinosvika gumi madhigirii.Zvinogona kuonekwa kuti kutonga kwekumhanya kwemhepo uye vhoriyamu yemhepo kwakakosha pakupisa tembiricha kutonga.Kuti udzore kumhanya kwemhepo uye vhoriyamu yemhepo, mapoinzi maviri anofanirwa kutariswa, ayo anogona kudzikisa lateral tembiricha mutsauko mu lead-isina reflow choto uye kugadzirisa solder mhedzisiro:
⑴Kumhanya kwefan kunofanirwa kudzorwa nefrequency conversion kudzikisa kukanganiswa kwevoltage pairi;
⑵ Deredza mhepo yekubuda kwemhepo yemidziyo zvakanyanya sezvinobvira, nekuti mutoro wepakati wemhepo yekuburitsa kazhinji hauna kugadzikana uye unogona kukanganisa kuyerera kwemhepo inopisa muchoto.
4. Lead-free reflow soldering ine kugadzikana kwakanaka uye inogona kuderedza kusiyana kwekushisa muchoto.
Kunyangwe kana isu tikawana yakakwana inotungamira-isina reflow oven tembiricha yekumisikidza, kuiwana kuchiri kuda kugadzikana, kudzokororwa uye kuenderana kwe lead-isina reflow soldering kuti ive nechokwadi.Kunyanya mukugadzirwa kwemutobvu, kana paine kudonha kushoma nekuda kwezvikonzero zvemidziyo, zviri nyore kusvetuka kunze kwehwindo rekuita uye kukonzera kutonhora kwekutengesa kana kukuvadzwa kwechigadzirwa chekutanga.Naizvozvo, vagadziri vanowedzera vari kutanga kuda kugadzikana kuyedzwa kwemidziyo.
