SMD ichava nemhando dzakasiyana dzehurema hunoitika, semuenzaniso, iyo chikamu chechikamu cheyakaomeswa isina solder, iyo indasitiri yakadana ichi chiitiko cheiyo monument.
Mumwe mugumo wechikamu warped nokudaro zvichiita kuti chiyeuchidzo chisina solder, zvikonzero zvakasiyana-siyana zvekuumbwa kwe.Nhasi, tichatsanangura zvikonzero zvechiitiko uye mamwe matanho ekuvandudza.
1.Solder paste printerhaina kufuratira, imwe mugumo wepadhi yakawanda tin, imwe mugumo ishoma
Iyi ndiyo magumo epamberi pechigamba chakakonzerwa, nekuda kwekusaenzana kwe solder paste kudhinda, solder paste printing kumativi ose maviri epedhi haisi chiyero chakafanana, zvichiita kuti kumashure kwekuputira kuparara nguva hakuna kufanana, zvichiita kuti kunetsana ndiko. hazvina kufanana, naizvozvo muromo mumwe wakamonyoroka kuita solder isina chinhu.
Nzira yakanakisisa yekuvandudza iyi ndeyokuwedzera SPI kuseri kwe solder paste kudhinda muchina, edza kuona kudhinda kwakashata, kudzivisa kuyerera kune welding uye ipapo dambudziko, kuitira kuti reworking nguva inopedza uye mari yakakwirira.
2.Sarudza uye isa muchinagomo magumo ese ari maviri haana kuputika kana kumisa
Mushure meSMD muchinainobata nzvimbo yekuiswa, inogona kuita kuti muromo wekusveta ubate kutsauka kana kamera kuverenga iyo bit nhamba yekuisa kurongeka kutsauka nekuda kwekudya kweiyo flyer, zvichizotungamira kune yekuisa offset, iyo padhi yekupedzisira inotumirwa zvimwe, imwe magumo yakatumirwa zvishoma kuti ibudise kune padhi kunze, zvichiita kuti iende kunguva yekudzorerazve welding apo nguva inopisa yekunyunguduka yakasiyana, kukwira kwetin nguva kwakasiyana, zvichiita kuti pave nekukakavadzana kwakasiyana, zvichikonzera hondo.
Nzira yekuvandudza dambudziko iri, kune rumwe rutivi ndeyekuchengetedza mounter's flyer uye kamera nguva dzose, kudzivisa kutora uye kuisa kutsauka.kune rumwe rutivi, kune bhajeti yekuwana aSMT AOI muchina, cherechedza kunaka kwekuisa.
3.Reflow soldering muchinachoto tembiricha curve kuseta dambudziko
Reflow soldering pachayo ine ina tembiricha nzvimbo, akasiyana tembiricha zone basa rakasiyana, mu preheating uye inogara tembiricha nhanho, zvimwe zvikamu zvinogona kunge zviri padivi pezvakakwira zvikamu, zvichikonzera kuti rimwe divi ripiswe zvakanyanya, mukupinda muchikamu chekupisa welding. tembiricha yakasiyana inotungamira kune solder namira kupisa kupisa nguva yekunyunguduka kwakasiyana, ichioneka yakamira monument isina chinhu welding.
Zvikonzero zvitatu zviri pamusoro apa ndizvo zvinowanzokonzeresa zvezvikamu zvakakanyiwa zvakamira piritsi isina solder, kana mukugadzira, chiitiko ichi chinogona kubva kune aya maficha ekugadzirisa dambudziko.
