Yintoni ekufuneka ihlawulwe ingqalelo xa ukhetha ibha yokukhanya kwe-LED elungileyo I-LED isasaza imichilo yokukhanya yokukhanya esiyisebenzisayo ngoku yomelele kwaye ihlala ihlala njalo, kwaye ubomi beshelufu ngokubanzi malunga neminyaka emi-3. Isiseko sokuqina kunye nokuqina kukuba iinkqubo ezihambelanayo kunye neenkcukacha kufuneka zilandelwe ngokungqongqo ngexesha lemveliso. Oku kulandelayo kudwelisa i-LED esasaza izibane zokukhanya ngexesha lemveliso. Izinto zokuhoya. 1. Nika ingqalelo kwi-anti-static, kwaye akuvumelekanga ngokungqongqo ukuba uchukumise ibhodi ye-PCB ngaphandle kokukhuselwa kwe-static, enokubangela umonakalo kwi-LED i-diffuse izibane ezibonisa ukukhanya. 2. Qaphela ukuba ungachukumisi i-lens ngaphandle kweeglavu, eziza kubangela iminwe kwi-lens.

Ichaphazela iziphumo zokukhanya. 3. Nika ingqalelo ukuba i-solder paste esetyenzisiweyo iphelelwe lixesha (ngokubanzi, i-solder paste emva kokuvula kufuneka isetyenziswe kwiiyure ezingama-24), kwaye umgangatho we-solder paste kufuneka ube mhle. Kungale ndlela kuphela apho ubomi benkonzo ye-LED yokusabalalisa ukukhanya okubonakalayo kuqinisekiswa.

4. Nika ingqalelo kwiglue yokunyanga, kufuneka uqinisekise ukuba umgangatho weglue kufuneka ube mhle. Yiglue ephilisayo enokumelana nobushushu obuphezulu. Ubushushu obuqhelekileyo bungama-70-90 degrees. Kuba amaso ezibane ziya kukhupha ubushushu xa zisetyenziswa.

Ukuba iglue yokuphilisa ayikwazi ukumelana nokushisa okuphezulu, kuya kubangela ukuba i-lens ziwe. 5. Qaphela ukuba i-lens ye-LED ye-diffuse light light bar kufuneka ibekwe endaweni, kwaye umgama phakathi kwe-lens kunye nebhodi ye-PCB akufanele ube mkhulu kune-0.1mm. 6. Qaphela ukuba i-lens ye-LED ye-diffuse light light bar ayinakuthotywa.

(I-angle yokuthambekela ayinakudlula i-1 ° C) 7. Izilumkiso zokubekwa kwe-SMT, umatshini wokubeka i-SMT kufuneka ulungelelanise idatha yeentsimbi zesibane kunye nezichasi. Kufuneka kungabikho skewing. 8. Qaphela ukuba ukushisa kwe-reflow soldering kufuneka kulawulwe ngokufanelekileyo, ngaphandle koko kuya kuchaphazela amaso wesibane se-LED.

9. Xa uhambisa iglue, kufuneka ulawule ubuninzi beglue. Ayinakugqithisa umphezulu webhodi yePCB ye-LED esasazekileyo ebonisa umtya wokukhanya. 10. Qaphela ukuba ukupakishwa kufuneka kuphathwe phantsi kwezixhobo ze-anti-static.

Ngaphezu koko, iingxowa ze-PE ezichasene ne-static zisetyenziselwa ukupakishwa kwaye emva koko zifakwe kwiibhokisi.
