12V 3mm Buluu LED Yomangidwa mu Resistor DC

12 Volt Blue Kudzera-dzenje LED ndi Blue koonekera anatsogolera

Common buluu SMD anatsogolera kapena buluu throuhg-dzenje anatsogolera amangotenga ali patsogolo voteji mu 3V. Pofuna kuti ntchito LED wolimba pa 12V voteji. Izi 304BD465D2L12V12 3mm Blue Kudzera-dzenje kutsogoleredwa nawo Integrated resistor imene mukhoza onetsetsani zinachititsa kuti mwachindunji olumikizidwa kwa chakudya 12V mphamvu. Yerekezerani ndi chisanadze waya 12V anatsogozedwa, zimenezi zinachititsa Nyali adzakhala amphamvu, odalirika

Gawo la 3mm kudzera-dzenje anatsogolera:

Magetsi magawo:

* Zimachitika patsogolo chikhalidwe panopa: Udindo 1% ndipo zimachitika lifupi = 10us.

* Soldering chikhalidwe: chikhalidwe Soldering ayenera kutha ndi 3 secongds pa 260 ℃

Electrucal Kuwala Kaperekedwe (TC = 25 ℃)

* Wowala mwamphamvu chimaonekera mwa ZWL600.

* Θ1 / 2 ZACHOKA-sxis ngodya pa zimene intenity wowala ndi theka axia wowala mwamphamvu;

Main ntchito:

* Wagalimoto ka kuyatsa;

* Njovu kuwala;

* Enigine kuyatsa;

* Njinga yamoto ka kuyatsa;

Tsatanetsatane mankhwala:

99,99% waya chiyero golide;

Silver yokutidwa chimango LED;

Wotchuka tchipisi kuwasindikiza;

Mkulu khalidwe epoxy;

Zotsimikizira patsogolo kudzera-dzenje anatsogolera:

Yerekezerani ndi SMD anatsogozedwa, kudzera-dzenje anatsogolera kupanga adzakhala zambiri zovuta. Kutanthauza kudzatenga kwambiri kupanga patsogolo ndi nthawi yopanga:

Choyamba, tiyenera kukonzekera Chip LED (uyu adzakhala yemweyo monga kupanga SMD anatsogolera); Kachiwiri, tiyenera kuika Chip anatsogolera mu chimango inatsogolera, kenako tiyenera golide woyenga waya kugwirizanitsa cathode ndi anode ya chimango LED. Apo pakubwera osiyana, kupanga SMD anatsogozedwa, tiyenera kuika epoxy kwa chimango kutsogozedwa ndi kudikira mpaka ziume ndi uvuni. Komabe, anatsogolera Nyali, tiyenera jekeseni epoxy mu nkhungu disolo ndi kuika zinthu zonse kuti uvuni kwa maola osachepera 8 mpaka iwo ziume. Pambuyo pake, tiyenera Aphunzitsi iwo kuchokera uvuni ndi kutenga LED kunja nkhungu. Ndiyeno tiyenera kudula zikhomo za zinachititsa kuti athe kukhala zosavuta mayeso.

Potsiriza, ife tiri inatsogolera. Pofuna kuonetsetsa khalidwe ndi yunifolomu wabwino monga chofunika. Tiyeneranso kuika onse zinachititsa kuti makina kulekana ndi iwo tidzakhala nawo LED ndi bins chomwecho.

Yosungirako zokwaniritsa:

1. Pewani anapitiriza kukhudzana kwa condensing chilengedwe chinyezi ndi kusunga mankhwala kuchokera kusintha mofulumira yozungulira kutentha;

2. LEDs ziyenera kusungidwa ndi kutentha ≤30 ℃ ndi chinyezi wachibale <60% ℃;

3. Mankhwala mu phukusi choyambirira losindikizidwa tikulimbikitsidwa kuti anasonkhana mwa maola 72 a kutsegula;

4. Mankhwala mu phukusi mpata kuposa sabata ayenera anaphika kwa maola 6-8 pa 85-10 ℃;

LED AKUWONONGA NJIRA

1, The Lea D phula la anatsogolera ayenera kufanana mamvekedwe a maenje ogwiritsa pa PCB pa Kusinthaku chigawo;

Tsogolerani-kupanga ukafunidwe kutsimikiza kutsogolera phula likufanana una phula;

Fotokozani chithunzi pansipa kwa yoyenera njira patsogolo kupanga;

Kodi si njira PCB kufufuza m'dera kukhudzana pakati pa leadframe ndi PCB kuteteza limadula;

anati:

○ lolondola kukhazikitsidwa njira;

× Pachithunzichi kukhazikitsidwa njira;

2. Pamene mawaya soldering kuti anawatsogolera, aliyense olowa waya ayenera payokha insulated ndi kutentha kuotcha chubu kuteteza yochepa dera kukhudzana.

Musati mtolo mawaya onse mwa mmodzi kutentha kuotcha chubu kupewa kukanikiza pakati amatsogolera anatsogolera;

Kukanikiza pakati mavuto amatsogolera anatsogolera akhoza kuwononga nyumba mkati ndi chifukwa cholephera;

anati:

○ lolondola kukhazikitsidwa njira;

× Pachithunzichi kukhazikitsidwa njira;

3. Ntchito kuima-offs (mkuyu 3) kapena spacers (mkuyu 4) pamalo adzatsekeredwa inatsogolera pamwamba PCB ya;

4. Pitirizani osachepera 3mm cl earance pakati m'munsi mwa mandala kutsogozedwa ndi woyamba kutsogolera unakhota (mkuyu. 5. mkuyu. 6)

5. Pa kutsogolera kupanga zipangizo ntchito kapena jigs kugwira amatsogolera adzatsekeredwa kotero kuti mphamvu kupinda sati kuwapereka kwa disolo LED ndi nyumba yake mkati;

Osachita kutsogolera kupanga kamodzi chigawo wakhala wokwera kumtunda PCB ya;

L ead Ndimapanga Opaleshoni

1. Tsogolerani Ndimapanga Opaleshoni;

2. Kodi kupinda kumam'phunzitsa kuposa kawiri (mkuyu 7.);

3. Pa soldering, chigawo chimakwirira ndi zopalira ayenera kusiya chilolezo kupewa kuwayika kuwononga mavuto anatsogolera pa soldering (mkuyu 8);

4. kunsonga ya soldering chitsulo ayenera konse disolo epoxy;

5. Mwa-dzenje anatsogolera m ali osayenerana ndi soldering reflow;

6. Ngati anatsogolera adzamva mipita angapo soldering kapena nkhope njira zina pamene gawo mwina pansi kutentha chonde fufuzani ndi Best zinachititsa kuti ngakhale;
