The main process parameters yereflow soldering midziyokufambisa kupisa, cheni yekumhanyisa kudzora uye kumhanya kwemhepo uye kudzora vhoriyamu yemhepo.
1. Kudzora kupisa kupisa mukatisoldering ovheni.
Parizvino, zvigadzirwa zvakawanda zvinoshandisa lead-isina tekinoroji, saka iyoreflow soldering muchinainoshandiswa ikozvino inonyanya kupisa mweyareflow soldering.Mune inotungamira-isina soldering process, zvinodikanwa kuti utarise kune kupisa kuchinjisa maitiro uye kupisa kwekuchinjana kushanda.Kunyanya kune zvikamu zvine simba guru rekupisa, kana zvakakwana kupisa kutengesa uye kuchinjana hazvigone kuwanikwa, chiyero chekupisa chichave chakanyanya kuderera pane icho chemidziyo ine diki yekupisa simba, zvichikonzera lateral tembiricha musiyano..Iyo yekuyerera kwemhepo maitiro eiyo reflow oven muviri inokanganisa zvakananga kukurumidza kwekupisa.Nzira mbiri dzinopisa dzekufambisa mhepo dzekuti reflow soldering ndeidzi: micro-circulation inopisa mhepo yekufambisa nzira, uye imwe inonzi diki-yekutenderera inopisa mhepo yekufambisa nzira.
2. Kudzora kwekumhanya kweketani yereflow soldering.
Kudzora kweyetani yekumhanya kweiyo reflow soldering michina inokanganisa lateral tembiricha musiyano wedunhu redunhu.Kazhinji kutaura, kudzikisa kumhanya kweketani kunopa mudziyo une hombe kupisa huwandu nguva yekupisa, nekudaro ichidzikisa lateral tembiricha musiyano.Asi mushure mezvose, kugadzika kwechigadziko chekushisa kwechoto kunoenderana nezvinodiwa zve solder paste, saka hazvibviri kuderedza kukurumidza kweketani pasina muganhu mukugadzirwa chaiko.
3. Kudzora kwekumhanya kwemhepo uye mhepo yemhepo ye reflow soldering michina.
Chengetedza mamwe mamiriro mureflow ovenisina kuchinjika uye inongoderedza kukurumidza kwe fan muovheni reflow ne30%, tembiricha pabhodhi redunhu inodonha neanenge 10 madhigirii.Zvinogona kuoneka kuti kutonga kwekumhanya kwemhepo uye vhoriyamu yemhepo kwakakosha pakupisa tembiricha kutonga.
Kuti uone kutonga kwekumhanya kwemhepo uye vhoriyamu yemhepo, mapoinzi maviri anofanirwa kutariswa kune:
a.Iko kumhanya kwe fan kunofanirwa kudzorwa ne frequency conversion kudzikisa simba rekuchinja kwemagetsi pairi;
b.Deredza mhepo yemhepo inoputika yemidziyo, nokuti mutoro wepakati wemhepo inoputika inowanzosagadzikana, iyo inokanganisa nyore nyore kuyerera kwemhepo inopisa muchoto.
