Uchungechunge lwe-Leader Micro Electronic lwe-SMD/SMT oluphinde lugelezeimoto encane yokudlidlizakuyisinqumo esihle kakhulu sokukhiqiza ngobuningi okuzenzakalelayo, okusheshayo kusetshenziswa imishini yokukhetha nokubeka. Lolu uchungechunge olulodwa lwemoto yokudlidliza olutholakala kutheyiphu ne-reel. Uma ubopha imoto ngesandla ku-PCB (okungukuthi, ukwenza ama-prototype), ungasebenzisi i-flux ngoba lokhu kungangena emotweni bese kuphazamisa ukusebenza kwayo. Lolu chungechunge lwemoto alukwazi ukugezwa ngemva kwenqubo yokugeleza kabusha.
Okwethuinjini encane edlidlizayoAma-motor okudlidliza e-SMD, afakwe ku-tape/reels yezingcezu eziyi-1000 nge-reel ngayinye futhi aklanyelwe ukuthathwa nokufakwa ngqo kusuka ku-reel. Ayindlela enhle kakhulu yokukhiqizwa kwesisindo esikhulu. Ane-"core" ewavumela ukuthi amelane namazinga okushisa aphezulu ahlobene nenqubo yokugoqa kabusha. Lawa ma-motor okudlidliza e-SMD angonakaliswa ukushisa okweqile. Sicela uqiniseke ukuthi ulandela iphrofayili yokushisa kwe-oven yokugoqa kabusha etholakala ephepheni ledatha lama-motor. Uma lawa ma-motor ezogoqwa ngesandla (okungukuthi, ukwenza ama-prototype), ungasebenzisi i-flux futhi usebenzise insimbi enamandla aphansi isikhathi esifushane ngangokunokwenzeka. Sicela uqaphele ukuthi lawaama-motor okudlidlizaAKUKWAZI ukugezwa.
Ukuxhumana KwasentwasahloboInjini edlidlizayo ye-smt:
Lolu chungechunge lwama-motor okudlidliza afakwa ebusweni, anezithinta zentwasahlobo, enza ukukhetha okuhle kakhulu ngezizathu ezahlukahlukene. Ngokungafani nama-motor ethu e-SMT Reflow, lawa ma-motor AWAKHELWANGELEKILE ukuthi ahlanganiswe ne-PCB. Izithinta zentwasahlobo kulawa ma-motor zimane zihlangane nama-contact pad aku-PCB. Lolu hlobo lwe-motor lunikeza izinzuzo ezithile ezihlukile kanje:
Izindleko Eziphansi: Lolu chungechunge lwama-motor luphansi ngo-10% ngezindleko kunezinjini zokudlidliza ze-SMT reflow.
Ukudluliselwa Kwamandla Okudlidliza Okusebenzayo: Lawa ma-motor angafakwa ebhokisini lepulasitiki lemikhiqizo lapho kungenzeka khona ukuthi izwakale futhi angabi manzi njengama-motor afakwe kwi-PCB.
Ukwethenjwa Okukhulisiwe: Ukudlidliza kuye kwaziwa ukuthi kunegalelo ekwehlulekeni komkhiqizo. Ukunciphisa inani lokudluliselwa kwamandla okunjalo kwi-PCB kungasiza kuphela kulokhu.
Ukusebenza Okuphezulu: Ezisetshenzisweni lapho injini ibhekene nemijikelezo yokusebenza ngokweqile, edlula isikhathi esilinganisiwe senjini, ukwehluleka kwenjini kungavela ngaphambi kwesikhathi. Ukufaka lolu hlobo lwenjini yokudlidliza, ngisho nasensimini, kuyashesha futhi kusebenza kahle njengoba kungekho ukushiswa okudingekayo ukuze uyisuse futhi uyishintshe. (kuyaqhubeka ngezansi)
