12V 3mm LED-ku-dhismay iska caabin DC ah

12 Waat Blue Iyada-dalool LED la Blue Taxaabay LED

Common buluug smd LED ama LED buluug throuhg-dalool uun helay doonaa danab Weeraryahanka in 3V. Si loo sameeyo shaqo LED ka xasilloon ee danab 12V. Tani 304BD465D2L12V12 3mm Blue Iyada-dalool LED helay resistor a dhafan, taas oo ka dhigi kartaa hubi LED in ay si toos ah ugu xiran in ay sahayda 12V xoog ah. Barbardhig la pre-silig 12V LED, this LED Lamps noqon more adag, lagu kalsoonaan karo doonaa

Aragti of 3mm dhex-dalool LED:

Qiyaasta Korontada:

* Sii wad xaalada hadda jirta: Waajibka 1% iyo ballaca garaaca = 10us.

* Xaaladda iibinta: Xaaladda iibka waa in lagu dhammeeyaa 3 sekan oo ah 260 ℃

Calaamadaha indhaha Electrucal (TC = 25 ℃)

*Xoojinta iftiinka waxaa lagu cabbiraa ZWL600.

* θ1/2 waa xagal ka baxsan-sxis kaas oo iftiinka iftiinka uu yahay kala bar xoogga iftiinka axia;

Codsiga Main:

* Nalalka lahjadda Vehicle;

* Iftiin jirridda,

* Nalalka Enigine;

* Nalalka lahjadda Baaskiilka;

Faahfaahinta Alaabta:

99.99% silig dahab ah oo nadiif ah;

Silver plated jir LED;

Chips calaamadeysan oo caan ah;

epoxy tayo sare leh;

Soo saarta horumarka ee LED dhex-dalool:

Barbar dhigtaa smd LED, wax soo saarka iyada oo-dalool LED noqdaan kuwa ka adag doonaa. Taas oo macnaheedu yahay waxa ay qaadan doontaa horumarka wax soo saarka badan iyo waqti wax soo saarka:

First of dhan, waxaan u baahan nahay si ay u diyaariyaan chip LED (tani waxay noqon doontaa mid ah sida wax soo saarka smd LED); Marka labaad, waxaan u baahan nahay inaan chip LED galay jir LED ah, ka dibna waxaan u baahan doonaa silig dahab saafi ah in ay ku xidhmaan ku cathode iyo anode jir LED. Waxaa jira yimaado oo kala duwan, Waayo, wax soo saarka smd LED, waxaan u baahan nahay in ay ku riday epoxy in ay jir LED oo sug ilaa ay qalalaan by foornada. Si kastaba ha ahaatee, waayo, LED Lamps, waxaan u baahan nahay si aad isugu durto epoxy galay caaryada ah gashto oo dhan waxyaalaha foornada ugu yaraan 8 saacadood ilaa ay qalalaan saaray. Ka dib markii in, waxaan u baahan nahay in ay iyaga tae ka foornada iyo ka baxdo ee LED of caaryada. Ka dibna waxaan u baahan nahay in uu yareeyo musmaarradii LED si ay u fududaan kara in imtixaanka.

Ugu dambeyntii, waxaan helay LED ah. In si ay u hubiyaan tayada iyo labis ah sida ugu fiican ee loo baahan yahay. Waxaan sidoo kale u baahan in ay ku riday oo dhan LED si mashiinka-soociddiisa, oo waxay u helnay doonaa LED la mid ah biinanka.

Xaaladaha Kaydinta:

1. Iska ilaali sii gaadhista deegaanka qoyaan isu keenida iyo sii alaabta ka soo gudubka deg deg ah ee heerkulka daarmayaay'e iska;

2. Kokes ku waa in lagu kaydiyaa heerkulka ≤30 ℃ iyo huurka qaraabo <60% ℃;

3. Product baakadda shaabadeeyey asalka ah waxaa lagu talinayaa in la soo ururay oo 72 saacadood gudahood furitaanka;

4. Product in xirmo furay toddobaadka ka badan waa in loo dubay 6-8 saacadood at 85-10 ℃;

LED hab sii kordhaya

1, garoonka LEA d ee LED waa in dhigma garoonka of godadka kordhaya on PCB inta lagu jiro meeleynta qayb;

Lead-sameynta yaabaa in loo baahdo si loo hubiyo inay hogaanka garoonka kulan garoonka godka;

U dir shaxanka hoose nidaamka hogaanka la xirrira habboon;

Ha wadada raad PCB ee degaanka xiriir ka dhexeeya leadframe iyo PCB si looga hortago-wareeggeedii gaaban;

xusay:

○ hab sii kordhaya saxda ah;

× hab sii kordhaya la qaldo,

2. Marka fiilooyin kabida, si LED ah, si wadajir ah silig kasta waa in la si gooni gooni ah ku dahaaran leh tube kulaylka-ihin si looga hortago in xiriir-circuit gaaban.

Ha gunti labada fiilooyin in tube ihin mid kulaylka si looga fogaado in qanjaruufo raadad LED ah;

Qanjaruufo stress on raadad keentay dhaawici kartaa qaab-dhismeedka gudaha iyo sababta failure;

xusay:

○ hab sii kordhaya saxda ah;

× hab sii kordhaya la qaldo,

3. Isticmaal taagan-offs (berdihii 3) ama spacers (berdihii 4) in ay meel ammaan ah LED kor ku PCB ah,

4. Yeelo ugu yaraan 3mm cl earance u dhaxeeya salka gashto LED iyo gacnta ugu horeysay hogaanka (5. berdihii. Berdihii. 6)

5. Inta lagu jiro hogaanka la xirrira, isticmaalka qalabka ama jigs si uu u qabto raadad ah si ammaan ah si ciidanka laabaya oo aan la kala qaado si ay siku LED iyo qaab-dhismeedka gudaha;

Ha u qabtaan hogaanka la xirrira mar component ayaa Jaha eee PCB ah,

L EAD U samaynta Hannaanka

1. hoggaami U samaynta Hannaanka;

2. Ha ka badan laba jeer la leexiyo raadad ah (berdihii 7.);

3. Inta lagu jiro, kabida, daboolida qayb iyo heysata tahay inuu ka tago ansixin si looga fogaado gelinayn dhaawac stress on LED lagu jiro, kabida (berdihii 8);

4. Caaradda birta, kabida, waa in aan marnaba taaban epoxy siku;

5. Iyadoo-dalool LED s waa la leheyn, kabida reflow;

6. Haddii LED u mari doona baas, kabida badan ama wejiga hababka kale ee ay qayb ka mid ah waxaa laga yaabaa in lagu qaado kulayl daran fadlan ka hubi Best LED waayo, waafaqid,
