Yuav ua li cas xaiv cov teeb ci LED hlaws hauv LED zaub?

Qhov tseem ceeb ntawm LED zaub yog LED teeb hlaws thiab LED chav tsev boards. Yog tias ib qho ntawm lawv muaj teeb meem, nws yuav cuam tshuam ncaj qha rau tag nrho qhov zoo ntawm LED zaub! Yog li, yuav ua li cas kom paub qhov txawv ntawm qhov zoo ntawm LED teeb hlaws thiab LED chav tsev boards yog qhov zoo ntawm LED thiab LED chav tsev boards. Cov teeb meem uas LED zaub cov tub lag luam saib xyuas, ntawm no yog ib txoj hauv kev los xyuas qhov zoo ntawm LED teeb hlaws thiab PCB chav tsev boards. Kuv vam tias nws yuav pab tau rau cov tub lag luam LED zaub. Tsis tas li ntawd, qhov zoo yog huab tais. Cov khoom lag luam thiab cov cuab yeej uas tsis kam lees qhov pheej yig thiab shoddy kuj yog qhov yuav tsum tau ua los ntawm cov chaw tsim khoom, kom tsis txhob ua kom cov nyhuv ntawm kev ua haujlwm ib txwm muaj thiab kev saib xyuas tsis tsim nyog ntawm cov tom ntej. LED lub cais. Qee lub tuam txhab LED chav tsev tsim khoom siv pheej yig hluav taws kub retardant ntawv boards lossis ib leeg-sided fiber boards raws li LED teeb raws li LED teeb rau cov nqi qis. Vim tias tag nrho cov iav fiber ntau PCB boards yog kim. Thaum pib, qhov sib txawv tsis tuaj yeem pom. Feem ntau, yog tias nws tsis yog ib xyoos, nws yuav tawg vim kev ya raws, kev puas tsuaj ultraviolet, oxidation, thiab lwm yam, ua rau tag nrho LED lub rooj tsavxwm yuav tsum tau muab pov tseg. High-quality LED chav boards yuav tsum yog ob-sided tag nrho-off iav fiber ntau PCB pawg thawj coj saib. Txawm hais tias tus nqi siab, qhov zoo yog guaranteed. Saib xyuas seb hom khoom siv IC siv puas zoo ib yam. Yam qauv ntawm IC thiab pes tsawg ICs siv, uas yog txaus los cuam tshuam qhov zoo ntawm LED chav tsev board. Qee lub tuam txhab LED zaub, txhawm rau txuag cov nqi, yuav txhob txwm txo cov ICs thaum lub sij hawm tsim khoom, lossis sib xyaw nrog lwm hom IC. Lawv tswb. Qhov muag liab qab tsis tuaj yeem paub qhov zoo ntawm cov hlaws dai. Nws tsuas tuaj yeem ua raws li kev sim mus sij hawm ntev, uas yog, kev kuaj kev laus uas cov kws tshaj lij hais. Txoj hauv kev ntawm cov chaw tsim khoom LED zaub dav dav yog: lub zog rau lub zog ua ntej lub Hoobkas, xyuas seb cov LED zaub tuaj yeem ua haujlwm li cas, yuav tsis raug sim rau lub sijhawm ntev. Vim tias ntau lub sijhawm thiab cov nqi ua haujlwm yuav tsum tau siv sijhawm ntau thiab nqi zog. Vuam zoo: Tshawb xyuas seb puas muaj cov khoom xau cov nplaum, cov ntawv nplaum tsis raug, thiab seb puas muaj cov khoom siv tube taw thiab cov burrs luv luv. Xyuas seb qhov txuas ncaj qha - hauv vuam cov pob qij txha yog du thiab puag ncig, seb lub rooj tsavxwm puas huv thiab zoo huv si, thiab tsis muaj kev sib txuas ntawm lub tshuab virtual. Txheeb xyuas qhov sib xws ntawm qhov flatness ntawm lub teeb thiab xim ntawm tus number case. Kev ntsuas fais fab-powered: qhov sib xws ntawm qhov teeb pom kev zoo ntawm lub zog-powered test; seb qhov kev ntsuas hluav taws xob puas muaj kev tiv thaiv zoo los ntawm CEM4953;. Cov khoom siv tseem ceeb ntawm LED teeb hlaws ntim ntim suav nrog brackets, chips, khoom siv lead ua cov pos hniav, cov kab tseem ceeb thiab ntim cov gels, thiab lwm yam. SMD (Surface Mountain Devices) yog hais txog qhov chaw ntim khoom ntim cov qauv LED, uas feem ntau suav nrog LED (Chicled) thiab PLCC cov qauv ntawm PCB pawg thawj coj saib. Cia peb qhia qee qhov kev txhim kho hauv tsev tam sim no hauv cov khoom ntim khoom. Tsis tas li ntawd xwb. PLCC (Plastic Leaded Chip Carrier) bracket yog tus nqa khoom ntawm SMD LED khoom, uas ua lub luag haujlwm tseem ceeb hauv kev ntseeg siab thiab lub teeb ntawm LED. Cov txheej txheem PLCC bracket ntau lawm suav nrog cov txheej txheem ntawm cov khoom siv hlau, electroplating, PPA (polybinzide) txhaj tshuaj molding, dabtsi yog khoov, tsib-sided peb-dimensional inkjet thiab lwm yam txheej txheem. Ntawm lawv, electroplating, hlau substrates, cov ntaub ntawv yas, thiab lwm yam. tuav tus nqi tseem ceeb ntawm lub bracket. Kev txhim kho kev tsim qauv ntawm lub bracket. Vim tias PPA thiab hlau khi yog ib qho kev sib khi ntawm lub cev, qhov sib txawv yuav loj dua tom qab qhov kub thiab txias rov qab rau hauv qhov cub, uas ua rau nws yooj yim rau cov dej vapor nkag mus rau hauv lub cuab yeej raws li cov hlau channel los cuam tshuam qhov kev cia siab ntawm kev cia siab. Txhawm rau txhim kho cov khoom lag luam kev ntseeg siab kom tau raws li cov khoom lag luam zoo LED uas ua tau raws li cov kev xav tau ntawm kev lag luam siab, qee qhov chaw ntim khoom tau txhim kho cov qauv tsim ntawm lub bracket, xws li kev siv cov qauv tsim qauv tsim, khoov ncab thiab lwm txoj hauv kev rau txuas cov dej vapor ntawm lub bracket rau hauv txoj kev nkag mus rau hauv txoj kev mus rau hauv txoj kev. Nyob rau tib lub sijhawm, ntau yam kev ntsuas dej tsis zoo xws li cov tso tsheb hlau luam tsis muaj dej, cov kauj ruam tsis muaj dej, thiab cov qhov dej tsis muaj dej ntxiv rau hauv lub bracket. Qhov kev tsim no tsis tsuas yog txuag cov nqi ntim khoom xwb, tab sis kuj txhim kho kev ntseeg tau ntawm cov khoom. Tam sim no, nws tau siv dav hauv cov khoom siv sab nraum zoov LED zaub. Tom qab tau ntim thiab ib txwm tuav los ntsuas qi ntawm LED bracket tsim los ntawm SAM (Scanning Acrentic Microscope). LED nti yog lub hauv paus ntawm LED teeb hlaws dai, thiab nws txoj kev ntseeg tau txiav txim siab lub neej thiab kev ua haujlwm luminous ntawm LED teeb hlaws thiab txawm tias LED zaub. Tus nqi ntawm LED nti nyiaj rau tag nrho cov nqi ntawm LED ntaus ntawv kuj tseem loj heev. Nrog rau tus nqi qis, qhov loj ntawm LED nti tau dhau los ua me thiab me, thiab nws kuj ua rau muaj teeb meem kev ntseeg siab. Nrog rau kev txo qhov loj me, PAD ntawm P electrode thiab N electrode kuj nqaim. Kev txo qis ntawm cov electrode PAD ncaj qha cuam tshuam rau qhov zoo ntawm cov vuam kab. Nyob rau tib lub sijhawm, qhov kev ncua deb A ntawm ob lub PADs kuj tseem yuav txo qis, uas yuav ua rau cov electrode tam sim no ua rau muaj qhov ntom ntom ntom ntom ntom ntom ntom ntom ntom, tam sim no sib sau hauv zos ntawm electrode. Tshaj siab, tsis sib xws, ci ntsa iab, yooj yim to, electrode poob, thiab txawm tias tsis muaj teeb pom kev zoo, thiab lwm yam, nws thiaj li ua rau txo qis kev ntseeg siab ntawm LED zaub. Cov kab tseem ceeb yog ib qho ntawm cov ntaub ntawv tseem ceeb rau kev ntim khoom LED. Nws txoj haujlwm yog kom paub txog kev sib txuas hluav taws xob ntawm cov nti thiab tus pins, uas ua lub luag haujlwm ntawm nti thiab lub ntiaj teb sab nraud. LED ntaus ntawv encapsulates cov kab tseem ceeb xws li kub, tooj liab xov hlau, tooj liab-plated tooj liab kab, thiab hlau alloy, thiab lwm yam. (1) Goldline. Cov kab golden yog dav siv, cov txheej txheem yog mature, tab sis tus nqi yog kim, uas ua rau cov nqi siab ntawm LED lub ntim. (2) Lawv ntsuj. Copper threads muaj qhov zoo ntawm pheej yig, zoo tshav kub dissipation cuam tshuam, thiab kev loj hlob qeeb ntawm cov hlau intervertebral tebchaw thaum lub sij hawm vuam kab. Qhov tsis zoo yog tias tooj liab yog ib qho yooj yim rau oxidize, siab hardness, thiab siab strain siv. Tshwj xeeb tshaj yog nyob rau hauv cov cua kub ib puag ncig ntawm lub keyhearted tooj liab roasted pob, qhov chaw ntawm tooj liab nto yog heev yooj yim mus oxidize, thiab tsim oxide zaj duab xis txo cov albuming kev ua tau zoo ntawm cov tooj liab hlau. Qhov no qhia txog kev xav tau ntau dua rau kev tswj cov txheej txheem hauv cov txheej txheem tsim khoom tiag tiag. (3) Tus tswv tswb. Txhawm rau tiv thaiv oxidation ntawm tooj liab xov hlau, tooj liab-plated tooj liab hlau maj mam nyiam cov xim ntawm kev lag luam ntim khoom. Qhov zoo ntawm kev siv tshuab muaj zog, nruab nrab hardness, zoo-welded thiab yog li-sized sphere yog haum rau high-density, multi-footed integrated circuit ntim. Tam sim no, cov kua nplaum encapsulated los ntawm LED zaub ntaus ntawv feem ntau suav nrog ob hom epoxy resin thiab silicon silicon. (1) epoxy resin. Epoxy resin yog qhov yooj yim rau kev laus, yooj yim los ntub, kub-resistant, thiab yooj yim hloov xim ntawm lub teeb luv luv-yoj thiab kub. Nws muaj qee yam toxicity nyob rau hauv lub xeev ntawm cov kua nplaum. Lub thermal stress tsis phim lub LED. Yog li ntawd, epoxy resin feem ntau yog ua phem. (2) Qhia nplais. Piv nrog rau epoxy resin, cov organic silicon muaj tus nqi siab - ua haujlwm zoo, rwb thaiv tsev zoo heev, dielectricity, thiab kev sib ze. Tab sis qhov tsis zoo yog tias cov roj nruj tsis zoo, thiab nws yooj yim nqus. Yog li nws tsis tshua muaj siv nyob rau hauv daim ntawv thov ntim ntawm LED zaub ntaus ntawv.
