SMT tora uye isa muchinainoreva kududzirwa kwenhevedzano yemaitiro etekinoroji pahwaro hwePCB.PCB zvinoreva A Printed Circuit Board.
Surface Mounted Technology ndiyo inonyanya kufarirwa Tekinoroji uye maitiro muindasitiri yegungano remagetsi parizvino.Yakadhindwa Circuit Board tekinoroji yegungano redunhu umo mameseji ekusangana asina mapini kana mapfupi anoiswa pamusoro peAkadhindwa Circuit board kana mamwe ma substrates uye anotengeswa pamwechete nenzira ye reflow welding, dip welding, nezvimwe.
Kazhinji, zvigadzirwa zvemagetsi zvatinoshandisa zvinogadzirwa nePCB pamwe neakasiyana macapacitor, resistors uye zvimwe zvikamu zvemagetsi zvinoenderana nedhizaini yedhizaini yedhizaini, saka marudzi ese emidziyo yemagetsi inoda akasiyana akasiyana eSMT yekugadzirisa tekinoroji.
SMT basic process zvinhu: solder paste kudhinda -> SMT kukwira ->reflow oven->AOImidziyooptical inspection -> kugadzirisa -> bhodhi.
Nekuda kweiyo tekinoroji maitiro akaomarara eSMT kugadzirisa, saka kune akawanda maSMT ekugadzirisa mafekitori, emhando yeSMT yakavandudzwa, uye maitiro eSMT, chinongedzo chese chakakosha, hachigone kuita chero chikanganiso, nhasi diki gadzira nemunhu wese pamwechete dzidza SMT reflow. welding muchina unounzwa uye yakakosha tekinoroji mukugadzirisa.
Reflow soldering midziyo ndiyo yakakosha midziyo muSMT musangano maitiro.Hunhu hwePCBA solder joint hunoenderana zvachose nekuita kwereflow soldering michina uye kuseta kwetembiricha curve.
Iyo reflow welding tekinoroji yakasangana nekuvandudzwa kweplate radiation kudziyisa, quartz infrared chubhu kudziyisa, infrared inopisa mhepo kupisa, kumanikidza kupisa kwemhepo kupisa, kumanikidza kupisa kwemhepo kupisa uye nitrogen kuchengetedza uye mamwe mafomu.
Kuwedzera kwezvinodiwa zvekutonhodza maitiro ekudzoreredza solder kwakasimudzirawo kuvandudzwa kwenzvimbo dzekutonhodza dzezvekufemesa solder midziyo, kubva pakutonhodza kwechisikigo uye kutonhora kwemhepo patembiricha yekamuri kusvika kumvura yekutonhodza masisitimu akagadzirirwa kushambadzira-isina lead.
Reflow soldering michina nekuda kwekugadzira maitiro ekudzora tembiricha kurongeka, kufanana kwetembiricha munzvimbo yekushisa, kumhanya kwekufambisa uye zvimwe zvinodiwa.Uye yakagadziridzwa kubva munzvimbo nhatu tembiricha shanu tembiricha zone, nhanhatu tembiricha nzvimbo, nomwe tembiricha zone, sere tembiricha zone, gumi tembiricha zone uye mamwe akasiyana welding masisitimu.
Zvikamu zvakakosha zve reflow soldering michina
1. Nhamba, kureba nehupamhi hwenzvimbo yetembiricha;
2. Symmetry yezvidziviriro zvepamusoro nepamusoro;
3. Kufanana kwekugovera kwekushisa munzvimbo yekushisa;
4. Kuzvimirira kwetembiricha yemhando yekufambisa kukurumidza kudzora;
5, inert gasi kudzivirira welding basa;
6. Gradient kutonga kwekutonhora kwenzvimbo yekudonha tembiricha;
7. Maximum tembiricha ye reflow welding heater;
8. Tembiricha yekudzora kurongeka kwe reflow soldering hita;
