Parizvino, vazhinji vagadziri vezvigadzirwa zvemagetsi zvepamberi kumba nekune dzimwe nyika vakakurudzira pfungwa nyowani yekugadzirisa michina "synchronous kugadzirisa" kuitira kuti vawedzere kudzikisira kukonzeresa pakuita basa rekugadzira.Ndokunge, kana ovheni yekudzokorodza iri kushanda yakazara, iyo otomatiki yekugadzirisa inoshandura sisitimu yemidziyo inoshandiswa kuita kuchengetedza uye kugadzirisa kweiyo reflow oven yakanyatsoenderana nekugadzirwa.Iyi dhizaini inosiya zvachose iyo yekutanga "shutdown kugadzirisa" pfungwa, uye inowedzera kuvandudza kugona kwekugadzira kweiyo SMT mutsara.
Zvinodiwa kuti process iitwe:
Midziyo yemhando yepamusoro inogona chete kuburitsa mabhenefiti kuburikidza nekushandiswa kwehunyanzvi.Parizvino, matambudziko mazhinji akasangana neruzhinji rwevagadziri mukugadzirwa kwe lead-isina soldering haina kungouya kubva kumidziyo pachayo, asi inoda kugadziriswa kuburikidza nekugadzirisa mukuita.
l Kugadzika kwechoto chekushisa curve
Nokuti iyo inotungamira-isina-isina soldering process hwindo idiki kwazvo, uye isu tinofanirwa kuve nechokwadi chekuti majoini ese ekutengesa ari mukati mewindo rekuita panguva imwe chete munzvimbo yekuyerera, saka, iyo inotungamira-isina reflow curve inowanzoisa "flat top" ( ona Mufananidzo 9).
Mufananidzo 9 "Flat top" muchoto chekushisa curve kugadzika
Kana izvo zvepakutanga zvikamu pabhodhi redunhu zvine misiyano mishoma mukupisa kwesimba asi zvinonyanya kunzwisiswa nekupisa kwekushisa, zvinonyanya kukodzera kushandisa "mutsara" tembiricha yevira curve.(Ona Mufananidzo 10)
Mufananidzo 10 "Linear" tembiricha yevira curve
Kugadzirisa uye kugadziriswa kwevheji yekushisa kwechoto kunoenderana nezvinhu zvakawanda zvakadai semidziyo, zvikamu zvepakutanga, solder paste, nezvimwewo. Nzira yekuisa haina kufanana, uye ruzivo runofanira kuunganidzwa kuburikidza nekuedza.
l Furnace tembiricha curve simulation software
Saka pane dzimwe nzira dzinogona kutibatsira nekukurumidza uye nemazvo kuseta tembiricha yevira?Tinogona kufunga kugadzira software nerubatsiro rwechoto tembiricha curve simulation.
Mumamiriro ezvinhu akajairwa, chero isu tichiudza software mamiriro edunhu redunhu, mamiriro echishandiso chepakutanga, nguva yebhodhi, kumhanya kweketani, tembiricha yekumisikidza uye kusarudzwa kwemidziyo, software inoteedzera tembiricha yevira inogadzirwa. mumamiriro ezvinhu akadaro.Izvi zvichagadziriswa pasina Indaneti kudzamara tembiricha yevira inogutsa yawanikwa.Izvi zvinogona kuchengetedza zvakanyanya nguva yekugadziridza mainjiniya kuti vadzokorore kugadzirisa curve, iyo inonyanya kukosha kune vanogadzira vane akawanda marudzi uye mabhechi madiki.
Ramangwana re reflow soldering tekinoroji
Zvigadzirwa zvenharembozha uye zvigadzirwa zvemauto zvine zvakasiyana zvinodiwa zve reflow soldering, uye dhizaini bhodhi kugadzirwa uye semiconductor kugadzirwa zvine zvakasiyana zvinodiwa zve reflow soldering.Diki-yakasiyana-siyana uye yakakura-vhoriyamu kugadzirwa kwakatanga kuderera zvishoma nezvishoma, uye misiyano yemidziyo zvinodiwa zvezvigadzirwa zvakasiyana yakatanga kuoneka zuva nezuva.Musiyano uripo pakati pekutengesa solder mune ramangwana haungoratidzike muhuwandu hwenzvimbo dzetembiricha uye sarudzo yenitrogen, musika wekutengesa reflow ucharamba wakagovaniswa, inova ndiyo inofanoona yekusimudzira tekinoroji reflow soldering tekinoroji mune ramangwana.
