Ama-PCB emojula ye-LED Ephakeme Kakhulu: Izixazululo Ezithuthukile Zesekethe Yezibonisi-Iphimbo Elihle kanye namamojula Okukhanya Ahlanganisiwe

Iyini i-High-Density LED PCB Technology

Ama-PCB wemojuli ye-LED enobukhulu obuphezulu asebenza njengesisekelo sokuboniswa kwephimbo elihle kanye nezinhlelo zokukhanyisa ezihlangene, okuvumela ukuhlanganiswa kwe-pixel ngaphakathi kwezici zefomu eziboshiwe. Lawa mabhodi esekethe akhethekile afinyelela ukujula kwe-pixel ngaphansi kuka-1.5mm kuyilapho egcina ubuqotho besignali, ukusebenza okushisayo, nokufana kokubona ezinkulungwaneni zama-elementi e-LED. Ubuchwepheshe bubhekana nezinselele ezibucayi ekubonisweni kwesizukulwane esilandelayo, okuhlanganisa ukuhlangana kwe-chip-on-board, ukulungiselelwa kwe-Mini LED, kanye nokusetshenziswa kwe-Micro LED kwezinhlelo zokusebenza kusukela ezindongeni zevidiyo ezisakazwayo kuya kuma-microdisplays ezimoto.

Idizayini Yesakhiwo Se-PCB Exinene Kakhulu

Ubuchwepheshe be-HDI nokucushwa kwesendlalelo

Ukwakhiwa kwe-High-density LED PCB kusebenzisa amabhodi ezendlalelo eziningi angaboni futhi angcwatshwe ngobuchwepheshe ukuze amukele umzila oyinkimbinkimbi endaweni elinganiselwe. Amadizayini ajwayelekile ahlanganisa izendlalelo ezine kuya kweziyisishiyagalombili ezinama-microvias ambozwe nge-laser anesilinganiso esingu-0.1mm noma esincane, esivumela umzila wesiginali ngaphansi kwamaphedi okukhweza e-LED. Ukubekwa kwengxenye kufeza ukubekezelelana okunembayo okungu-±0.05mm kokuma kwephikseli okungaguquki, kuyilapho isikhala sokulandela umkhondo sifinyelela ku-0.075mm ukuze kugcinwe ubuqotho besignali kuwo wonke amasekhethi abashayeli agcwele phama.

I-Copper Architecture Yamandla Nokusabalalisa Okushisayo

Ukulungiswa kwesendlalelo sethusi kumadizayini e-LED PCB aqinile kufeza imisebenzi kagesi kanye neyokushisa. Izendlalelo zangaphakathi zinesisindo sethusi esingu-2 kuya ku-3 oz ukuze zibhekane nezidingo ze-amperage ngaphandle kokwehla kwamandla kagesi ngokweqile, kuyilapho izindiza zamandla zisebenzisa ukuthululwa kwethusi okuqinile ukuze kusatshalaliswe kahle ugesi. Lesi sakhiwo sezendlalelo eziningi sakha inethiwekhi ehlanganisiwe yokusabalalisa ukushisa esebenza ngokubambisana nezici zokuphatha ukushisa ezizinikele ukuze kususwe ukushisa kuma-array e-LED agxilile.

Izinto zokwakha kanye nezixazululo ezishisayo ze-High-Density LED PCB

Imibandela Yokukhetha I-substrate

Ukukhetha okubalulekile kokukhiqizwa kwe-PCB ye-LED ephezulu kakhulu kulinganisa ukusebenza okushisayo nezidingo zohlelo lokusebenza:

• Ama-PCB asekelwe ku-aluminium – I-Thermal conductivity ye-1.5 kuya ku-3 W/m·K ifanele amamojula e-LED okuhweba ekuminyanisweni kwamandla okumaphakathi.
• I-Ceramic substrates – I-Aluminium oxide noma i-aluminium nitride enikeza ukuguquguquka okushisayo okudlula u-6 W/m·K kuzinhlelo zokusebenza ezisebenza kahle kakhulu.
• FR4 laminate - Isixazululo esingabizi kakhulu sezinhlelo zokusebenza lapho ukuminyana kwamandla kuvumela ukusebenza okwanele okushisayo ngezinto ezijwayelekile.

I-Thermal Management Architecture

I-Thermal nge-array ebekwe ngokuqondile ngaphansi kwamaphedi akhwezayo e-LED adlulisa ukushisa ukusuka ohlangothini lwengxenye kuya ekuxhumaneni kwe-heatsink kusendlalelo esingezansi. Ngobubanzi obusuka ku-0.2 kuye ku-0.3mm ngesikhala esithuthukisiwe ngokulingisa okushisayo ukuze kukhuliswe ukusakazeka kokushisa ngaphandle kokufaka engcupheni ukuminyana kwemizila. Idizayini yemaski ye-Solder ithatha ama-alloys e-Sn-Ag-Cu angenawo umthofu kuyilapho inikeza ukuhambisana kokwanda okushisayo kuwo wonke amazinga okushisa okusebenza ukusuka ku--40°C kuya ku-85°C.

Ukusebenza kukagesi ku-High-Density LED PCB Design

Ubuqotho Besiginali kanye Nokulawulwa Kokuphazamiseka

Izakhiwo ze-PCB ye-LED enobukhulu obuphezulu zigcina ubuqotho besignali kuwo wonke amashaneli afanayo asebenza aze afike kumakhulu amaningana ama-megahertz ngokusebenzisa umzila olawulwayo wokuvinjelwa. Amadizayini asebenzisa amapheya ahlukene angama-50-ohm anokuphela ngakunye noma okungu-100-ohm ukuze avimbele ukubonakaliswa kwesignali kanye ne-crosstalk phakathi kwemigqa yomshayeli eseduze. Ukuqhubeka kwendiza ephansi kuzo zonke izendlalelo kunikeza izindlela zokubuya ezinezithiyo eziphansi, kuyilapho ukuqaqa ama-capacitor eduze nomshayeli ngamunye we-IC kunciphisa umsindo wokunikezwa kwamandla ukuze kusebenze i-LED evumelanisiwe kulo lonke uhlelo.

Ukulinganisa Kwamanje kanye Nokuphathwa kwe-EMI

Ukukhanya okufanayo kuzo zonke izinhlobo ze-LED ezixinene kakhulu kudinga ukusatshalaliswa kwamanje okunembile ngokusebenzisa ukwakheka kwe-PCB okunesu :

• Umzila wamandla obanzi - Izindlela eziningi ezihambisanayo ezisuka ezindaweni zokunikezela ziye kumaqoqo e-LED zinciphisa ukwehla kwamandla kagesi aphikisayo.
• Ukuvikela indiza ephansi - Izingqimba zomhlabathi ezinikezelwe zinciphisa ukukhishwa kwemisebe kanye nokuba sengozini kokuphazamiseka kwangaphandle.
• Ukwenziwa ngcono kokugcwalisa i-Copper - Amaphethini akhethiwe ezendlalelo zesignali ahlinzeka ngokuvikela kwe-electromagnetic ngenkathi igcina ukuminyana komzila.

Ukukhiqiza I-High-Density LED PCB Assemblies

I-Precision SMT kanye ne-COB Assembly

Ukuhlanganiswa kwe-LED PCB okunobukhulu obuphezulu kudinga ukunemba kokubekwa ngaphakathi kuka-±0.02mm kwezingxenye ezincane njengephakheji engu-0201 noma idayisi le-LED elingenalutho ekucushweni kwe-chip-on-board. Izinqubo zokugeleza kabusha zisebenzisa amaphrofayili okushisa alawulwa ngokucophelela ukuvimbela ukucindezeleka kokushisa ezindaweni zokuhlangana ze-LED ngenkathi kuqinisekiswa amalunga e-solder athembekile. Ukugeleza kabusha komkhathi we-nitrogen kunciphisa i-oxidation futhi kuthuthukisa ukumanzisa kumaphethini ephedi aminyene abonakala kulawa mabhodi akhethekile.

Izindlela Zokuqinisekisa Ikhwalithi

Amaphrothokholi okuhlola aphelele aqinisekisa ukusebenza kukagesi nokokubona:

• Ukuhlola okuzenzakalelayo - Ithola amaphutha okubekwa, amaphutha e-solder, kanye nokungcola ngaphambi kokuhlolwa kwamandla.
• Ukuhlolwa kwe-in-circuit - Iqinisekisa ukuqhubeka kukagesi kanye nokuhlukaniswa phakathi kwamasekhethi kuwo wonke umhlangano.
• Ukuhlolwa kokusebenza kokubona - Ilinganisa ukufana kokukhanya, ukungaguquguquki kombala, namazinga amaphikseli afile.
• Imithethonqubo yegumbi lokuhlanza - Iyadingeka ezinhlelweni zokusebenza ze-Micro LED ukuvimbela ukungcola kwengxenye ekucushweni kwe-ultra-fine-pitch.
