Reflow oveni anoshandiswa muSurface Mount Technology (SMT) kugadzira kana semiconductor kurongedza maitiro.Kazhinji, mahovhoni ekudzoreredza chikamu chemagetsi ekubatanidza mutsara, kusanganisira kudhinda uye kuisa michina.Muchina wekudhinda unodhinda solder paste paPCB, uye muchina wekuisa unoisa zvikamu pane akadhindwa solder paste.
Kugadzira Reflow Solder Pot
Kugadzira reflow oven kunoda ruzivo rweiyo solder paste inoshandiswa mugungano.Iyo slurry inoda nitrogen (yakaderera oksijeni) nharaunda panguva yekudziya?Reflow zvirevo, kusanganisira tembiricha yepamusoro, nguva iri pamusoro pe liquidus (TAL), nezvimwewo?Kana aya maitiro ekuita achinge azivikanwa, injinjiniya inogona kushanda kumisikidza reflow oven resipi nechinangwa chekuwana imwe reflow profile.Reflow oven resipi inoreva kudziya kwehovhoni marongero, kusanganisira tembiricha yenzvimbo, convection rates, uye gasi kuyerera.Iyo reflow profile ndiyo tembiricha iyo bhodhi "inoona" panguva yekudzokorora.Pane zvinhu zvakawanda zvekufunga nezvazvo paunenge uchigadzira reflow process.Bhodhi redunhu rakakura sei?Pane here zvidimbu zvidiki pabhodhi zvinogona kukuvadzwa nepamusoro convection?Ndeipi yakanyanya kuganhura tembiricha yechikamu?Pane dambudziko here nekukura kwekushisa nekukurumidza?Chii chinodiwa chimiro chechimiro?
Zvimiro uye Zvimiro zveReflow Oven
Mahovhoni mazhinji ekudzoreredza ane otomatiki resipi yekuseta software inobvumira reflow solder kugadzira resipi yekutanga zvichienderana nebhodhi maitiro uye solder paste zvakatemwa.Ongorora reflow soldering uchishandisa thermal rekodha kana trailing thermocouple waya.Reflow setpoints inogona kugadziriswa kumusoro / pasi zvichibva pane chaiyo thermal profile vs. solder paste tsanangudzo uye bhodhi / chikamu chekushisa zvipingamupinyi.Pasina otomatiki yekumisikidza yekuseta, mainjiniya anogona kushandisa iyo default reflow mbiri uye kugadzirisa iyo resipi kuti itarise maitiro kuburikidza nekuongorora.
