Li-ovine tsa Reflow li sebelisoa mekhoeng ea tlhahiso ea Surface Mount Technology (SMT) kapa mekhoa ea ho paka ea semiconductor.Ka tloaelo, li-ovens tsa reflow ke karolo ea mohala oa kopano ea elektronike, ho kenyelletsa le mechini ea khatiso le ea ho bea.Mochini oa khatiso o hatisa pente ea solder ho PCB, 'me mochini o behang o beha likarolo holim'a pente ea solder e hatisitsoeng.
Ho theha Pitsa ea Reflow Solder
Ho theha setofo sa reflow ho hloka tsebo ea solder paste e sebelisoang kopanong.Na seretse se hloka tikoloho ea nitrogen (oksijene e tlase) nakong ea mocheso?Litlhaloso tsa ho phalla hape, ho kenyelletsa mocheso o phahameng, nako e kaholimo ho mokelikeli (TAL), joalo-joalo?Hang ha litšobotsi tsena tsa ts'ebetso li tsejoa, moenjiniere oa ts'ebetso a ka sebetsa ho theha risepe ea ontong ea reflow ka sepheo sa ho fihlela profil e itseng ea reflow.Recipe ea ontong ea reflow e bua ka litlhophiso tsa mocheso oa ontong, ho kenyeletsoa mocheso oa libaka, litefiso tsa convection, le likhahla tsa phallo ea khase.Setšoantšo sa reflow ke mocheso oo boto e "bonang" nakong ea ts'ebetso ea ho tsosolosa.Ho na le lintlha tse ngata tse lokelang ho nahanoa ha ho etsoa mokhoa oa ho tsosolosa.Boto ea potoloho e kholo hakae?Na ho na le likarolo tse nyane haholo botong tse ka senyehang ke convection e phahameng?Tekanyo e phahameng ea mocheso oa motsoako ke bokae?Na ho na le bothata ka sekhahla sa kholo ea mocheso ka potlako?Sebopeho sa profaele se lakatsehang ke sefe?
Likarolo le Likarolo tsa Reflow Oven
Li-ovens tse ngata tsa reflow li na le software ea ho seta recipe e lumellang morekisi oa reflow ho etsa risepe ea ho qala e ipapisitseng le litšobotsi tsa boto le litlhaloso tsa solder paste.Sekaseka reflow soldering ka ho sebelisa sehatisi sa mocheso kapa terata ea thermocouple.Li-setpoints tsa Reflow li ka fetoloa holimo / tlase ho ipapisitse le boemo ba 'nete ba mocheso vs. lintlha tsa paste ea solder le lithibelo tsa mocheso oa boto / karolo.Ntle le tlhophiso ea risepe ea othomathike, lienjineri li ka sebelisa profaele ea "reflow" ea kamehla le ho lokisa risepe ho tsepamisa ts'ebetso ka tlhahlobo.
