Amanqaku asibhozo amisela umgangatho womboniso we-LED ogcwele umbala

1. I-Anti-static

Umzi-mveliso wendibano yokubonisa kufuneka ube nemilinganiselo elungileyo yokuchasana ne-static.Umhlaba onikezelweyo ochasene nestiti, umgangatho ochasene ne-static, intsimbi yokudambisa i-anti-static, i-anti-static table mat, i-anti-static ring, i-anti-static impahla, ukulawula ukufuma, ukumisa izixhobo (ingakumbi i-foot cutter), njl. iimfuno, kwaye kufuneka zitshekishwe rhoqo ngemitha engatshintshiyo .

2. Qhuba uyilo lwesekethe

Ilungiselelo lomqhubi we-IC kwibhodi yesekethe yomqhubi kwimodyuli yokubonisa nayo iya kuchaphazela ukukhanya kwe-LED.Ekubeni imveliso yangoku yomqhubi we-IC ihanjiswa kumgama omde kwibhodi yePCB, ukuhla kwamandla ombane kwindlela yokuhambisa kuya kuba kukhulu kakhulu, okuya kuchaphazela amandla ombane osebenzayo we-LED kwaye kubangele ukuba ukukhanya kwayo kunciphe.Sihlala sifumanisa ukuba ukukhanya kwee-LED ezijikeleze imodyuli yokubonisa iphantsi kunombindi, yeso sizathu.Ngoko ke, ukuqinisekisa ukuhambelana kokukhanya kwesikrini somboniso, kuyimfuneko ukuyila umzobo wokusabalalisa isiphaluka somqhubi.

3. Yila ixabiso langoku

Umbane okhoyo we-LED yi-20mA.Ngokuqhelekileyo, kucetyiswa ukuba ubuninzi bokusebenza okwangoku bungabi ngaphezu kwe-80% yexabiso legama.Ngokukodwa kwimiboniso enechaphaza elincinci, ixabiso langoku kufuneka lithotywe ngenxa yeemeko ezimbi zokulahla ubushushu.Ngokutsho kwamava, ngenxa yokungahambelani kwesantya sokunciphisa ii-LED ezibomvu, eziluhlaza, eziluhlaza, ixabiso langoku lee-LED eziluhlaza kunye nohlaza kufuneka lincitshiswe ngendlela ejoliswe kuyo ukuze kugcinwe ukuhambelana kwebhalansi emhlophe yesikrini sokubonisa. emva kokusetyenziswa kwexesha elide.

4. Izibane ezixubeneyo

Ii-LED zombala ofanayo kunye namanqanaba ahlukeneyo okukhanya kufuneka zixutywe, okanye zifakwe ngokuhambelana nomzobo wokufaka ukukhanya owenziwe ngokomthetho ocacileyo ukuqinisekisa ukuhambelana kokukhanya kombala ngamnye kwisikrini sonke.Ukuba kukho ingxaki kule nkqubo, ukukhanya kwendawo yesiboniso kuya kuba kukungahambelani, okuya kuchaphazela ngokuthe ngqo umphumo wokubonisa umboniso we-LED.

5. Lawula ukuqina kwesibane

Kwii-LED ze-in-line, kufuneka kubekho iteknoloji yenkqubo eyaneleyo yokuqinisekisa ukuba i-LED i-perpendicular kwibhodi ye-PCB xa idlula eziko.Nakuphi na ukuphambuka kuya kuchaphazela ukuhambelana kokukhanya kwe-LED esetyenzisiweyo, kwaye iibhloko zombala ezinokukhanya okungahambelaniyo ziya kubonakala.

6. Ubushushu be-solder kunye nexesha

Ubushushu kunye nexesha lokuwelda phambi kwamaza kufuneka kulawulwe ngokungqongqo.Kucetyiswa ukuba ubushushu be-preheating yi-100℃±5℃, kwaye ubushushu obuphezulu akufunekanga budlule kwi-120℃, kwaye ubushushu bokufudumala kufuneka bunyuke kakuhle.Ubushushu be-welding yi-245℃±5℃.Kucetyiswa ukuba ixesha alifanele lidlule imizuzwana emi-3, kwaye musa ukungcangcazela okanye ukuthuthumela i-LED emva kwesithando somlilo de ibuyele kwiqondo lokushisa eliqhelekileyo.Iiparamitha zeqondo lokushisa lomatshini wokudibanisa amaza kufuneka zihlolwe rhoqo, ezichongwa ziimpawu ze-LED.Ukushisa ngokugqithiseleyo okanye ukuguquguquka kweqondo lokushisa kuya kulimaza ngokuthe ngqo i-LED okanye kubangele iingxaki ezifihliweyo zekhwalithi, ngakumbi kwii-LED ezinobungakanani obuncinci kunye ne-oval efana ne-3mm.

7. Ulawulo lwe-welding

Xa umboniso we-LED ungakhanyisi, kukho amathuba angaphezu kwama-50% okuba kubangelwa ziindidi ezahlukeneyo ze-solder ye-virtual, ezifana ne-LED pin soldering, i-IC pin soldering, i-pin header soldering, njl njl. Ukuphuculwa kwezi ngxaki kufuna. ukuphuculwa okungqongqo kwenkqubo kunye nokomelezwa kokuhlolwa komgangatho ukusombulula.Uvavanyo lokungcangcazela phambi kokuba ushiye umzi-mveliso ikwayindlela elungileyo yokuhlola.

8. Uyilo lokutshatyalaliswa kobushushu

I-LED iya kuvelisa ubushushu xa isebenza, ubushushu obuphezulu kakhulu buya kuchaphazela isantya sokuthomalalisa kunye nokuzinza kwe-LED, ngoko ke uyilo lokuphelisa ubushushu lwebhodi yePCB kunye noyilo lokuphuma komoya kunye nobushushu bekhabhinethi luya kuchaphazela ukusebenza kwe-LED.
