(Integrated Circuit) yana nuna cewa ana iya tafiyar da shi kai tsaye ta hanyar ƙananan ƙirar lantarki. Aikace-aikacen yau da kullun ya wuce alamun matsayi zuwa hasken aiki kamar hasken baya na maɓalli ko madannai, ƙananan nuni, da ba da haske ga alamomi ko sigina akan allunan sarrafawa.

2. Girman Kunshin da Ƙayyadaddun Injiniya

An ayyana jikin LTW-C181LDS5-GE ta hanyar daidaitaccen ƙirar kunshin EIA (Ƙungiyar Masana'antu ta Lantarki). Launin ruwan tabarau rawaya ne, yayin da tushen haske kansa ƙirar fari ce ta InGaN. Haɗin ruwan tabarau mai launin rawaya tare da ƙirar fari yana taimakawa wajen siffanta fitar da haske da yuwuwar gyara halayen launi. An ba da duk mahimman girmansu na jikin kayan aiki a cikin milimita tare da daidaitaccen jurewar ±0.1 mm sai dai idan an faɗi. Wannan ingantaccen sarrafa girma yana tabbatar da daidaitaccen sanyawa da sakamakon gishiri yayin haɗa PCB.

3. Ƙimar da Halaye

Wannan sashe yana ayyana iyakokin aiki da sigogin aiki na LED a ƙarƙashin takamaiman yanayin gwaji.

3.1 Ƙimar Matsakaiciya Mafi Girma

Waɗannan ƙimar suna wakiltar iyakokin damuwa waɗanda sama da su lalacewar dindindin na na'urar na iya faruwa. An ƙayyade su a yanayin zafin muhalli (Ta) na 25°C. Matsakaicin ɓarnawar wutar lantarki shine 76 milliwatts (mW). Ya kamata ƙarfin gaba na DC bai wuce 20 mA ba don ci gaba da aiki. Don aikin bugun jini, ana ba da izinin ƙarfin gaba na kololuwa na 100 mA a ƙarƙashin tsarin aiki mai tsauri na 1/10 tare da faɗin bugun jini na 0.1ms. Na'urar na iya aiki a cikin kewayon zafin muhalli na -20°C zuwa +105°C kuma ana iya adana ta a cikin yanayin zafi daga -40°C zuwa +105°C. Wani muhimmin ƙima don haɗawa shine yanayin gishiri na infrared, wanda aka ƙayyade shi azaman jure 260°C na matsakaicin dakika 10, wanda ya yi daidai da yanayin reflow na rashin gubar (Pb-free).

3.2 Shawarar Yanayin Reflow na IR don Tsarin Ba tare da Gubar ba

Haɗin gishiri mai nasara yana buƙatar takamaiman bayanan zafin jiki. Don gishiri mara gubar, ana ba da shawarar matakin dumama kafin har zuwa 150-200°C. Matsakaicin zafin jiki yayin reflow bai kamata ya wuce 260°C ba, kuma lokacin da ya wuce wannan matsakaicin zafin jiki ya kamata a iyakance shi zuwa matsakaicin dakika 10. Yana da mahimmanci a lura cewa ƙira daban-daban na PCB, man gishiri, da nau'ikan tanda suna buƙatar siffanta bayanan; ƙimar da aka bayar jagorori ne bisa gwajin tabbatarwa na matakin kayan aiki.

3.3 Halayen Lantarki da Na Gani

Waɗannan su ne ƙimar aikin yau da kullun da aka auna a Ta=25°C da ƙarfin gaba (IF) na 5 mA, wanda shine gwaji na yau da kullun da yanayin aiki. Ƙarfin haske (Iv), ma'aunin hasken da ake gani, ya bambanta daga mafi ƙarancin 112.0 millicandelas (mcd) zuwa matsakaicin 224.0 mcd. Kusurwar kallo (2θ1/2), wanda aka ayyana shi azaman kusurwar da ƙarfin haske ya ragu zuwa rabin ƙimar kololuwa, shine digiri 130, yana nuna tsarin katako mai faɗi sosai. Ƙarfin gaba (VF) yawanci yana tsakanin 2.70V zuwa 3.15V a 5mA. Ma'auni na launi akan zanen CIE 1931 sune x=0.284 da y=0.272, wanda ke ayyana takamaiman batu a cikin sararin launin fari. Ƙarfin baya (IR) yana da ƙasa sosai, tare da matsakaicin microamperes 2 (μA) a ƙarfin baya (VR) na 5V. Muhimman bayanan suna bayyana cewa jurewar ma'auni na launi shine ±0.01, kuma ba a tsara na'urar don aiki a ƙarƙashin baya ba; gwajin VR don dalilai na bayanai kawai ne.

4. Tsarin Matsayi na Bin

Saboda bambance-bambancen halitta a cikin masana'antar semiconductor, ana rarraba LED zuwa kwandon aiki don tabbatar da daidaito ga mai amfani na ƙarshe. LTW-C181LDS5-GE yana amfani da tsarin binning mai girma uku.

Idan tsaftacewa ya zama dole bayan gishiri ko saboda gurɓatawa, kawai ya kamata a yi amfani da takamaiman kaushi don guje wa lalata kunshin filastik. Hanyar da aka ba da shawarar ita ce a nutsar da LED a cikin barasa na ethyl ko isopropyl alcohol a yanayin zafin daki na yau da kullun na ƙasa da minti ɗaya. Dole ne a guji munanan sinadarai ko waɗanda ba a bayyana su ba.

6.2 Shawarar Tsarin Faɗin Haɗin PCB

An ba da zane wanda ke nuna mafi kyawun tsarin faɗin tagulla akan PCB don gishiri LED. Wannan tsarin yana tabbatar da samar da fillet ɗin gishiri daidai, ƙarfin injiniya mai kyau, da kuma zubar da zafi daidai. Bin wannan shawarar shine mabuɗin don cimma haɗin gishiri mai dogaro da kuma hana kabari (inda ƙarshen kayan aiki ya tashi daga faɗin yayin reflow).

6.3 Ƙayyadaddun Kunshin Tef da Reel

Ana ba da kayan aikin a cikin tsarin tef ɗin mai ɗauka don sarrafawa ta atomatik. Faɗin tef ɗin shine 8 mm. Ana nannade tef ɗin akan daidaitaccen reel mai diamita 7-inch (178 mm). An ba da cikakkun girmansu don aljihun tef ɗin, tef ɗin rufewa, da cibiyar reel don tabbatar da dacewa da kayan aikin ciyarwa. Muhimman bayanan sun ƙayyade cewa an rufe aljihun fanko, kowane reel yana ƙunshe da guda 5000, kuma kunshin ya yi daidai da ƙayyadaddun ANSI/EIA 481.

7. Bayanan Taka Tsantsan da Amincewa

7.1 Aikace-aikacen Da Ake Nufi da Amincewa

An tsara LED don amfani a cikin kayan lantarki na yau da kullun. Don aikace-aikacen da ke buƙatar amincen musamman ko inda gazawar za ta iya haifar da rayuwa ko lafiya (misali, jirgin sama, na'urorin likita, tsarin amincen sufuri), ana buƙatar tuntuba na musamman da cancanta, saboda waɗannan sun wuce daidaitaccen amfani.

7.2 Yanayin Ajiya da Hankan Danshi

Ajiya daidai yana da mahimmanci don hana shan danshi, wanda zai iya haifar da fashewar kunshin yayin tsarin reflow mai zafi (wanda aka sani da \"popcorning\"). A cikin ainihin jakar kariya ta danshi tare da desiccant, ya kamata a adana LED a ≤30°C da ≤90% danshi na dangi (RH) kuma a yi amfani da shi cikin shekara guda. Da zarar an buɗe jakar, yanayin ajiya dole ne ya zama ≤30°C da ≤60% RH. Ya kamata a yi gishiri reflow na kayan aikin da aka fallasa zuwa iskar muhalli (daga jakar da aka rufe) cikin sa'o'i 672 (kwanaki 28), wanda yayi daidai da Matakin Hankan Danshi (MSL) 2a. Idan wannan taga ya wuce, ana buƙatar gasa a kusan 60°C na aƙalla sa'o'i 20 kafin haɗawa don cire danshin da aka sha.

Don gishiri reflow: dumama kafin zuwa 150-200°C, matsakaicin zafin jiki ≤260°C, lokaci a kololuwa ≤10 seconds, kuma matsakaicin zagaye biyu na reflow ana ba da izini. Don gishiri na hannu tare da ƙarfe: zafin jiki ≤300°C, lokacin gishiri ≤3 seconds, kuma zagaye ɗaya na gishiri kawai ana ba da izini. Wuce waɗannan iyakoki na iya lalata aikin LED ko haifar da lalacewa ta dindindin.

7.4 Taka Tsantsan na Zubar da Wutar Lantarki (ESD)

LED yana da hankali ga zubar da wutar lantarki da ƙaruwar wutar lantarki. Dole ne a aiwatar da ingantattun matakan sarrafa ESD yayin sarrafawa da haɗawa. Wannan ya haɗa da amfani da bel ɗin wuyan da aka kafa, tabarmi masu hana tashin hankali, da tabbatar da cewa duk kayan aikin suna da tushe daidai. Rashin kiyaye taka tsantsan na ESD na iya haifar da gazawar na'urar a ɓoye ko bala'i.

8. Abubuwan Ƙira da Bayanan Aikace-aikace

Lokacin haɗa wannan LED cikin ƙira, dole ne a yi la'akari da abubuwa da yawa. Faɗin kusurwar kallo na digiri 130 yana sa ta dace da aikace-aikacen da ke buƙatar hasken yanki mai faɗi ko ganuwa daga kusurwoyi masu faɗi, kamar alamomin matsayi akan na'urori. Tsayin siriri na 0.55mm ya dace da hasken baya a cikin yadudduka a cikin tarin tarin kamar nunin wayar hannu. Kewayon ƙarfin gaba (2.7-3.15V) yana nufin sau da yawa ana iya tafiyar da shi kai tsaye daga wadataccen wutar lantarki na 3.3V tare da mai iyakance ƙarfi mai sauƙi, kodayake ana ba da shawarar direba mai ƙarfi don mafi kyawun kwanciyar hankali da tsawon rai. Dole ne a mutunta ƙimar zafi na 76mW na ɓarnawar wutar lantarki; Tsarin PCB ya kamata ya ba da isasshen yanki na tagulla don zubar da zafi, musamman idan yana aiki kusa da matsakaicin ƙarfin yanzu. Cikakken tsarin binning yana ba da damar zaɓi daidai don aikace-aikacen masu mahimmanci na launi, amma masu ƙira ya kamata su ƙayyade kwandon da ake buƙata lokacin yin oda. Don hasken baya na madannai, za a yi amfani da LED da yawa daga kwandon ƙarfi da hue iri ɗaya don tabbatar da daidaitaccen haske da launi a duk maɓallai.
