Imiphi Imikhiqizo Yochungechunge Oludidiyelwe Lwesibani Sezitshalo Oyifunayo?

Uyini umthombo wokukhanya we-COB ohlanekezelwe: Ngemuva kwentengo yeminyaka yakamuva, imakethe esemthethweni yomthombo wokukhanya we-COB iye yazinza kancane kancane, futhi isikhala sokunciphisa amanani sincane kakhulu. umkhuba emakethe. Ukuze uqhudelane ngesabelo semakethe esikhulu kanye nengcindezi ezindlekweni, abakhiqizi abakhulu bagxilise ukunaka kwabo kuma-chips ahlanekezelwe. Iyiphi imikhiqizo yochungechunge ehlanganisiwe yesibani sezitshalo etholakala kumikhiqizo yochungechunge lwezitshalo ezihlanganisiwe ze-Shenzhen. Ukusebenzisa amasongo e-anti-static, ama-anti-static pads, izingubo zokusebenza ezingaguquguquki nezicathulo zokusebenza, amagilavu ​​nama-anti-static capacitor konke kuyizinyathelo ezisebenzayo zokuvimbela i-static nokukhuphuka. I-Welding: Sebenzisa i-soldering iron man hand Welding: Kunconywa ukusebenzisa i-soldering iron engaphansi kuka-20W, futhi izinga lokushisa lensimbi yokunamathisela akumele ligcinwe lingekho ngaphezu kuka-300 C, futhi isikhathi sokushisela asidluli imizuzwana engu-3. I-back welding: (A) I-Push ngokuvamile inciphisa izindleko ezingaba ngu-15%. Mayelana nokusebenza, ngedizayini enengqondo nemojula, imojula yomthombo wokukhanya we-COB ingagwema kahle ububi bezibhamu zamachashazi kanye nokucwebezela okukhona ekuhlanganisweni kwamadivayisi omthombo wokukhanya wokuhlukanisa. Ungakwazi futhi ukwengeza inhlanganisela ye-chip ebomvu efanele ukuze unganciphisi ukusebenza kahle nempilo yomthombo wokukhanya nempilo. Ngaphansi kwesisekelo, thuthukisa ngempumelelo umbala womthombo wokukhanya (okwamanje uchungechunge oluhlanganisiwe lwemikhiqizo yezitshalo ze-Shenzhen lufuna, okutshala ukukhanya okuhlanganisiwe kochungechunge lwamalambu afile omkhiqizo (njengoba kuboniswe emfanekisweni oboniswe esithombeni) Kwenzeka ngezinye izikhathi, nezinye izinto zinamathele ebusweni be-colloid ngesikhathi senqubo yokushisela ukuze kulimaze indawo ye-colloid isikhathi eside. Iphuzu lokuthuthukisa: Ukuqinisekiswa kokuhlolwa kokunokwenzeka kwamapharamitha weglue wokupakisha womkhiqizi; ngokomkhawulo wezinga lokushisa onikezwe umenzi wokupakisha, umkhiqizi wohlelo lokusebenza lwe-LED uhlola ukuba nokwenzeka kwesakhiwo sokupholisa;. Futhi okokubona kwesibili okuhlanekezelwe akukafaneli kahle, futhi ukukhanya kungaphansi ngo-10-12% kunokufakwa okusemthethweni. Yize lona leli qembu njengamanje lingaba ngaphansi kuka-8%, lisabhekene nalezi zinkinga. Eminye yemikhiqizo yefomethi ye-COB isivuthiwe futhi izindleko ziphansi. I-Pour COB isebenzisa ngokugcwele i-chip ukuze imelane nemikhiqizo yochungechunge oludidiyelwe lwesibani sesitshalo se-Shenzhen samanje nesagolide samahhala ukuze uthole ukuthi yiluphi uchungechunge oludidiyelwe lwesibani lwezitshalo. Okwesine, imithombo yokukhanya ehlanganisiwe ye-LED yangaphakathi emnyama ibangela izibani ezifile: Ukuhlaziywa kwembangela embi: Amakhemikhali (isulfure, i-halogen nezinye izinto) abangela i-vulcanization ku-workshop yokupakisha; Izixhumanisi zokushisa okuphezulu njenge-welding zizosheshisa ukuvuthwa kwezinto ezinjalo, okuthinta ukusekelwa kwangaphakathi komthombo wokukhanya ohlanganisiwe we-LED.
