Chengetedzo yekushandiswa kweSMT reflow oveni.

smt reflow oven is smt back-end midziyo, basa guru nderekupisa kunyungudutsa solder paste, uyezve rega zvigadzirwa zvemagetsi zvidye tini, kuitira kuti zvigadziriswe pane pcb pad, saka.smt reflow midziyondechimwe chezvikamu zvitatu zvikuru zve smt, reflow soldering Migumisiro uye zvinofurira zvakakosha pamhando yezvigadzirwa zvinogadzirwa.

1. Kugadziriswa kwenzvimbo yekushisa haigoni kugadziriswa pasina.Maparamita enzvimbo yetembiricha akanyorwa pamusoro anotemerwa zvichienderana nekurapa chaiko kuti nzvimbo yewelding pcb board inotora 90% yenzvimbo inoshanda yestencil inotakura muchoto chemoto, uye chiyero chekutakura bhandi i75cm± 10cm/S.ye.Kana paine mutsauko mukuru munzvimbo yeakagadziridzwa pcb bhodhi, iyo bhandi yekumhanyisa inofanirwa kuve yakanyatso-tuned kuti iwane yakanaka welding mhedzisiro.Nheyo yakawanda yekugadziriswa ndeyekuti: kana nzvimbo yepcb board iri diki, kumhanya kwebhandi remambure kunokurumidza kukurumidza;apo nzvimbo yepcb board yakakura, kumhanya kwebhandi re mesh kunononoka zvishoma, uye zvinhu zvose zviri pasi pekuwana zvakanaka welding effect;

2. PID parameters yetafura yekudzora tembiricha haizogadzirwe zvakasununguka;

3. Iyo inopinza uye yekubuda yemuchina we reflow solder inofanirwa kudzivirira kunze kwemhepo yechisikigo ichivhuvhuta mukati mekushandisa, izvo zvinokanganisa kusimba kwekushisa muchoto uye kukanganisaweldingkunaka;

4. Paunenge uchitumira kunze kwePCB workpiece kubva pachiteshi chekubuda chevira reflow, zvakakosha kudzivirira njodzi yekupisa ruoko rwemushandisi;inofanirwawo kudzivirira bhodhi rePCB kuti rirege kuungana muchiteshi chekuburitsa, zvichiita kuti bhodhi rePCB riwire kana bhodhi rePCB pakubuda.Low solder simba pasi pepamusoro tembiricha mamiriro eSMD zvikamu zvinodonha nekuda kwekudonha kana kupwanya maitiro;

5. Ita basa rakanaka mukuchengetedza kwezuva nezuva kwewelding muchinamidziyo: chenesa pamusoro pemidziyozuva rega rega kuti irege kusvibiswa, tinya bhatani rekuwedzera mafuta kamwe chete pasvondo mune yemanyorero maitiro ekuwedzera mafuta, uye zora cheni yeroller nemafuta ekuzora anopisa (BIO-30);mukugadzirwa kunoramba kuripo, pamwedzi Kwete pasi pekaviri: Tarisa kuwedzera tembiricha yekuzora mafuta kuchoto mota uye yega yega inotenderera shaft vhiri;

6. Tarisa uone kana waya yepasi yemuchina welding yakabatana zvakavimbika usati watanga muchina zuva rega rega;

7. Mushure mekugadzirisa dambudziko, batidza simba guru rekushandisa uye shandura tsvuku tsvuku-yakafanana nehowa yekumisa chimbichimbi newachi kuti udzokere kumamiriro ekutanga ekushanda.Kana muchina wakadzimwa, PCB uye simbi inotakura mesh bhandi haifanirwe kumiswa muchoto chichiri mukupisa kwakanyanya, uye bhandi rekutakura rinofanira kumiswa mushure mekunge tembiricha yemuchina yadonha.
