Izinyathelo zokuphepha zokukhiqiza nokugcinwa kwezibani ze-LED nemichilo yokukhanya

Izinyathelo zokuphepha zokukhiqiza nokugcinwa kwezibani ze-LED nemichilo yokukhanya Ngesikhathi senqubo yokukhiqiza umugqa we-LED, kuzoba nesenzakalo sokufa okungamanga kwe-LED (okungukuthi, i-LED ayikhanyi). Izizathu zalesi simo zimi kanje: 1. Ugesi omile ushisa u-1:1 Ngenxa yokuthi i-LED iyingxenye ezwelayo ye-electrostatic, uma umsebenzi wokuvikela i-electrostatic ungenziwanga kahle phakathi nenqubo yokukhiqiza, i-chip ye-LED izoshiswa ngenxa kagesi omile, okuzobangela ukufa okungamanga komugqa we-LED. 1:2 Isilinganiso sokuvimbela lesi simo ukuqinisa ukuvikelwa kwe-electrostatic. Bonke abasebenzi abathinta ama-LED kufanele bagqoke amagilavu ​​angaguquki kanye namaringi amile ngokuhambisana nemithethonqubo, futhi amathuluzi namathuluzi kufanele kumiswe phansi. 2. Ukulimala kwezinga lokushisa eliphezulu Ukumelana nokushisa okuphezulu kwe-2: 1 LED akukuhle. Ngakho-ke, uma izinga lokushisa lokushisela kanye nesikhathi sokushisela se-LED kungalawulwa kahle ngesikhathi sokukhiqiza nokugcinwa, i-chip ye-LED izolimala ngenxa yokushisa okuphezulu kakhulu noma izinga lokushisa eliphezulu eliqhubekayo, okuholela ku-LED Isenzakalo sokugqwayiza okumisiwe komugqa wokukhanya.

2:2 Izinyathelo zokuvimbela lesi simo yilezi: ukwenza umsebenzi omuhle ekulawuleni izinga lokushisa kwe-reflow soldering ne-soldering iron, sebenzisa umuntu okhethekile onomthwalo wemfanelo, kanye nokuphathwa kwefayela okukhethekile; i-soldering iron isebenzisa insimbi elawulwa ngokushisa elawulwa ngokushisa ukuze ivimbele ngokuphumelelayo izinga lokushisa eliphezulu lensimbi yokunamathisela ekushiseni i-chip ye-LED. 3. Umswakama uqhuma ekushiseni okuphezulu kwe-3: 1 Uma iphakheji le-LED livezwa emoyeni isikhathi eside, lizothatha umswakama. Uma ingancishisiwe ngaphambi kokusetshenziswa, umswakama wephakeji ye-LED uzothintwa izinga lokushisa eliphezulu kanye nesikhathi eside ngesikhathi sokufakwa kabusha kwe-soldering. Ukunwetshwa kokushisa kubangela ukuthi iphakheji ye-LED iqhume, okubangela ngokungaqondile ukuthi i-chip ye-LED ishise futhi yonakale. 3:2 Isixazululo: Indawo yokugcina ama-LED kufanele igcinwe ezingeni lokushisa elilinganayo kanye nomswakama. Ama-LED angasetshenzisiwe kufanele abhakwe kuhhavini cishe ku-80 ° amahora angu-6-8 ukuze kukhishwe umswakama ngaphambi kokusetshenziswa okulandelayo, ukuze kuqinisekiswe ukuthi ama-LED asetshenzisiwe ayafana. Ngeke kube khona ukumuncwa komswakama.
