Umehluko phakathi kwe-laser welding kanye ne-elective wave soldering

Njengoba zonke izinhlobo zemikhiqizo ye-elekthronikhi seziqala ukwenziwa miniaturized, ukusetshenziswa kobuchwepheshe bokushisela bendabuko ezingxenyeni ezintsha ze-elekthronikhi kunokuhlolwa okuthile.Ukuze kuhlangatshezwane nesidingo esinjalo semakethe, phakathi kobuchwepheshe benqubo yokushisela, kungashiwo ukuthi ubuchwepheshe buthuthukiswa ngokuqhubekayo, futhi izindlela zokushisela nazo zihlukahlukene kakhulu.Lesi sihloko sikhetha indlela yendabuko yokushisela i-wave welding ekhethiwe kanye nendlela yokushisela ye-laser ukuze iqhathaniswe, ungabona ukunethezeka okulethwe ukuqanjwa kabusha kwezobuchwepheshe ngokucace kakhudlwana.

Isingeniso ekuhlanganisweni kwegagasi okukhethiwe

Umehluko osobala kakhulu phakathi kwe-wave soldering ekhethiwe kanye ne-wave soldering yendabuko ukuthi ku-wave soldering yendabuko, ingxenye engezansi ye-PCB icwiliswa ngokuphelele ku-solder ye-liquid, kuyilapho i-wave soldering ekhethiwe, izindawo ezithile kuphela ezithintana ne-solder.Ngesikhathi senqubo yokuhlanganisa, indawo yekhanda le-solder iyalungiswa, futhi i-manipulator ishayela i-PCB ukuze ihambe kuzo zonke izinkomba.I-flux kufanele futhi ifakwe ngaphambili ngaphambi kokuyi-solder.Uma kuqhathaniswa ne-wave soldering, i-flux isetshenziswa kuphela engxenyeni engezansi ye-PCB ukuze ithengiswe, kune-PCB yonke.

I-selective wave soldering isebenzisa imodi yokufaka i-flux kuqala, bese ishisisa ibhodi lesifunda/i-flux evulayo, bese isebenzisa i-solder nozzle ukuze ihlanganiswe.I-manual manual soldering iron idinga i-point-to-point welding iphuzu ngalinye lebhodi lesifunda, ngakho-ke kukhona ama-welding operators amaningi.I-Wave soldering isebenzisa imodi yokukhiqiza eyizimboni enepayipi.Imibhobho yokushisela enosayizi abahlukene ingasetshenziselwa ukuhlanganisa inqwaba.Ngokuvamile, ukusebenza kahle kwe-soldering kunganyuswa izikhathi ezingamashumi amaningana uma kuqhathaniswa ne-soldering manual (ngokuya ngomklamo webhodi lesifunda).Ngenxa yokusetshenziswa kwethangi elincane eliguquguqukayo eliguquguqukayo kanye nezimbobo zokushisela eziguquguqukayo (umthamo wethangi likathayela ucishe ube ngu-11 kg), kungenzeka ukugwema izikulufo ezithile ezingaguquki nokuqinisa ngaphansi kwebhodi lesifunda ngokuhlela ngesikhathi sokushisela Izimbambo nezinye izingxenye, ukuze ugweme umonakalo obangelwa ukuthintana ne-solder eshisa kakhulu.Lolu hlobo lwemodi yokushisela aludingi ukusebenzisa ama-pallets welding ngokwezifiso nezinye izindlela, ezifanele kakhulu izindlela zokukhiqiza ezihlukene, ezincane.

I-selective wave soldering inezici ezilandelayo ezisobala:

  • Umthwali we-welding we-Universal
  • Ukulawula iluphu ye-nitrogen evaliwe
  • I-FTP (Iphrothokholi Yokudlulisa Ifayela) uxhumano lwenethiwekhi
  • Uma uthanda imbobo yesiteshi esikabili
  • I-Flux
  • Kulungele
  • Ukwakhiwa okuhlangene kwamamojula amathathu okushisela (imojula yokushisa, imojula yokushisela, imojula yokudlulisa ibhodi lesifunda)
  • Ukufafaza kwe-Flux
  • Ubude begagasi ngethuluzi lokulinganisa
  • GERBER (ukufakwa kwedatha) ukungenisa ifayela
  • Ingahlelwa ungaxhunyiwe ku-inthanethi

Ekuhlanganisweni kwamabhodi wesekethe wengxenye ye- through-hole, i-elective wave soldering inezinzuzo ezilandelayo:

  • Ukusebenza kahle kokukhiqiza okuphezulu ekushiseni, kungafinyelela izinga eliphakeme lokushisela okuzenzakalelayo
  • Ukulawulwa okunembile kokuma komjovo we-flux nevolumu yomjovo, ukuphakama kwe-microwave peak, kanye nendawo yokushisela
  • Ukwazi ukuvikela ubuso beziqongo ze-microwave nge-nitrogen;nokwandisa inqubo nemingcele for solder ngamunye joint
  • Ukushintsha okusheshayo kwemibhobho enosayizi abahlukene
  • Inhlanganisela yephuzu eligxilile lokudayiswa kwejoyinti elilodwa le-solder nokulandelanisa kwezikhonkwane zokuxhuma i- through-hole
  • Izinga le-"fat" kanye "nomzimba omncane" we-solder shape ingasethwa ngokuvumelana nezidingo
  • Amamojula amaningi okushisa ngaphambili (i-infrared, umoya oshisayo) kanye namamojula okushisa angezwe ngaphezu kwebhodi
  • Iphampu ye-solenoid engalungiseki
  • Ukukhethwa kwezinto zokwakha kulungele ngokuphelele ukusetshenziswa kwe-solder engenamthofu
  • Idizayini yesakhiwo se-modular inciphisa isikhathi sokulungisa
