I-1400nm ir iholele kudedele i-infrared ebomvu ye-3mm

Ubukhulu bezamalambu abasezingeni eliphansi be-IR ebomvu kude;

Le 3MM IR ye-LED inesayizi yelensi ye-3x5.3mm. Qhathanisa nolunye usayizi we-3mm wezibani eziholwa ngumgodi we-LED, lena uthole imisebe enamandla kakhulu. Ngesikhathi sokukhiqizwa, isinyathelo seFrist siyi-welding chip endebeni yohlaka lwe-LED futhi sifaka i-glue emgqeni wokubumba. Emva kwalokho, faka uhlaka lwe-LED phakathi kokubumba kweglue. Kule ntuthuko, sizokwazi ukulungisa i-angle yokubuka, lapho sisondelana kakhulu khona, ukubukwa okubanzi esizothola. Ngosayizi ofanayo wephakheji, i-engela ebuka kakhudlwana esikutholayo, indawo enkulu yemisebe sizothola futhi ibanga le-radia lizolahleka ngasikhathi sinye. Singakuguqula lokhu njengokudingeka kwakho.

I-3mm ngokusebenzisa-hole I-LED LED Usayizi womkhiqizo:

* Lolu hlaka lwe-LED lwe-LED luyatholakala ku-UV LED, i-LED ephuzi, i-LED eluhlaza, i-LED eluhlaza okwesibhakabhaka ne-red led

Izimo Zokugcina

1. Gwema ukuvezwa okuqhubekayo endaweni evumelana nomswakama futhi ugcine umkhiqizo usuka kude nezinguquko ezisheshayo ekushiseni okukhona;

2. Ama-LED kufanele agcinwe ngokushisa ≤30 ℃ kanye nomswakama ohlobene <60% ℃;

3. Umkhiqizo ephaketheni lokuqala elivaliwe kunconyelwa ukuthi lihlanganiswe kungakapheli amahora angama-72 okuvulwa;

4. Umkhiqizo kwiphakheji elivuliwe isikhathi esingaphezu kwesonto kufanele ubhokwe amahora angama-6-8 ku-85-10 ℃;

Indlela Yokukhuphuka Kwe-LED

1, ukuhola komholi we-LED kumele kuhambisane nokuphindwa kwezimbobo ezikhuphukayo kwi-PCB ngesikhathi sokubekwa kwengxenye;

Ukuqanjwa kokuhola kungadingeka ukuze kuqinisekiswe ukuthi iphimbo lokuhola lifane ne-hole pitch;

Bhekisa kwisibalo esingezansi ukuze uthole izinqubo ezifanele zokwakha;

Ungahambisani umlandeli we-PCB endaweni yokuxhumana phakathi kohlaka oluholayo ne-PCB ukuvikela amasekethe amafushane;

2. Lapho izintambo zombumbulu ziholele, i-wire ngayinye ijoyinti kufanele ifakwe ngokuhlukile ngeshubhu elishisayo lokushisa ukuvikela ukuxhumana okufushane kwesizungu.

Musa ukunxuselisa zombili izintambo ku-tube eyodwa yokushisa shrink ukugwema ukuncipha okuholela kwe-LED;

Ukuncipha kwengcindezi ku-Led Lead kungalimaza izakhiwo zangaphakathi futhi kubangele ukwehluleka;

3. Sebenzisa ama-Stand-offs (Fig 3) noma ama-spacers (Fig 4) ukubeka ngokuphepha i-LED ngenhla kwe-PCB;

4. Gcina ubuncane bokuvulwa kwe-3mm phakathi kwesisekelo selensi ye-LED kanye ne-bend yokuqala yokuhola (Umdwebo 5. Fig. 6)

5.Ukuthola i-lead eholayo, sebenzisa amathuluzi noma ama-jigs ukubamba okuphephile ukuze amandla okugoba angadluliselwa kwilensi ye-LED nezinhlaka zawo zangaphakathi;

Ungenzi ukwakheka kokuhola uma isakhi sifakwe kwi-PCB;

Hola izinqubo zokwakha

1. Hola izinqubo zokwakha;

2. Musa ukugoba okuholela ngaphezu kokubili (Fig. 7);

3. Ngesikhathi sokuthengisa, izembozo zezakhi kanye nabanikazi kufanele zishiye imvume ukuze zigweme ukubeka ukucindezela okulimazayo ku-LED ngesikhathi sokuthengisa (Umdwebo 8);

4. Ithiphu yensimbi yokuthengisa ye-soldering akufanele ithinte i-lens epoxy;

5. Ngokuhamba nge-leds-hole ahlukene ayihambelani ne-Reflew Soldering;

6. Uma i-LED izodlula i-soldering eminingi noma ibhekane nezinye izinqubo lapho ingxenye ingahle ibekwe khona ekushiseni okukhulu sicela uhlole nge-LED engcono kakhulu yokuhambisana;
