Pakati pe-1990s, pakanga paine maitiro ekuendesa kune infrared + inopisa mhepo yekudziya mukuyerera kwekutengesa muJapan. Inopiswa ne30% infrared rays uye 70% mhepo inopisa semutakuri wekupisa. Iyo infrared inopisa air reflow oven inonyatso kusanganisa zvakanakira infrared reflow uye kumanikidza convection inopisa mhepo reflow, uye inzira yakanaka yekupisa muzana remakore rechi21. Inoshandisa zvizere maitiro eiyo yakasimba infrared radiation yekupinda, yakanyanya kupisa kupisa uye kuchengetedza simba, uye panguva imwe chete zvinobudirira kukunda mutsauko wetembiricha uye kudzivirira mhedzisiro ye infrared reflow soldering, uye inogadzirira iyo inopisa mhepo inoyerera solder.

Iyi mhando yereflow solderingchoto chakavakirwa paIR vira uye inowedzera mhepo inopisa kuita kuti tembiricha muchoto iwedzere yunifomu. Kupisa kunotorwa nezvinhu zvakasiyana uye mavara akasiyana, ndiko kuti, kukosha kweQ kwakasiyana, uye inokonzeresa tembiricha inokwira AT yakasiyanawo. Semuyenzaniso, pasuru yeSMD yakaita seLC itema phenolic kana epoxy, uye inotungamira isimbi chena. Kana ichingopisa, tembiricha yemutobvu yakaderera pane yayo nhema SMD muviri. Kuwedzera mhepo inopisa kunogona kuita kuti tembiricha iwedzere kufanana, uye kukunda mutsauko mukunyura kwekupisa uye kushava kwemumvuri. Infrared + hot air reflow oveni dzave kushandiswa zvakanyanya munyika.

Sezvo mwenje infrared ichave neyakaipira mhedzisiro ye shading uye chromatic aberration muzvikamu zvine hurefu hwakasiyana, mhepo inopisa inogona zvakare kupeperetswa kuti iyananise chromatic aberration uye kubatsira kushomeka kwemakona ayo akafa. nitrogen inopisa ndiyo yakanyanya kunaka kuti mweya unopisa ufuridzwe. Iko kumhanya kwe convective kupisa kupisa kunoenderana nekumhanya kwemhepo, asi yakanyanyisa kumhanya kwemhepo kunokonzeresa kutamiswa kwezvikamu uye kukurudzira oxidation yemajoini anotengeswa, uye kumhanya kwemhepo kunofanirwa kudzorwa pa1. Om/s~1.8III/S yakakodzera . Kune marudzi maviri echizvarwa chemhepo inopisa: axial fan chizvarwa (zviri nyore kugadzira laminar kuyerera, uye kufamba kwayo kunoita kuti muganho weimwe neimwe tembiricha isanyatsojeka) uye tangential fan chizvarwa (feni inoiswa kunze kweheater, iyo inogadzira eddy currents pane panhizha kuitira kuti tembiricha yega yega igone kudziirwa chaiko.
