1.1 Qeexida iyo asalka SMD

Tignoolajiyada baakadaha SMD waa nooc ka mid ah baakadaha qaybaha elegtarooniga ah. SMD, oo u taagan Surface Mounted Device, waa tignoolajiyada si weyn loogu isticmaalo warshadaha wax soo saarka elektiroonigga ah ee baakadaha isku dhafan ee chips wareegyada ama qaybaha kale ee elektiroonigga ah si toos ah loogu dhejiyo dusha sare ee PCB (Printed Circuit Board).

1.2 Tilmaamaha ugu muhiimsan

Cabbir yar:Qaybaha baakadaysan ee SMD waa kuwo is haysta, awoodna u siinaya is dhexgalka cufnaanta sare, taas oo faa'iido u leh naqshadaynta alaabada elektiroonigga ah ee la yareeyey iyo kuwa fudud.

2. Falanqaynta Tignoolajiyada Baakadaha COB

2.1 Qeexida iyo asalka COB

Tiknoolajiyada baakadaha COB, oo u taagan Chip on Board, waa farsamada baakadaha halkaasoo chips si toos ah loogu dhejiyo PCB (Board Circuit Printed). Tiknoolajiyadan waxaa ugu horreyn loo isticmaalaa in lagu xalliyo arrimaha kuleylka LED-ka iyo in la gaaro is-dhexgalka adag ee u dhexeeya chip-ka iyo guddiga wareegga.

2.2 Mabda'a Farsamada

Baakadaha COB waxay ku lug leedahay ku xidhida jajabyada qaawan substrate-ka isku xidha iyada oo la isticmaalayo xabagyada korantada ama kuwa aan fiicneyn, oo ay ku xigto isku xidhka siliga si loo sameeyo isku xirka korantada. Inta lagu jiro baakooyinka, haddii jajabka qaawan uu soo gaadho hawada, waa uu wasakhaysan karaa ama wuu dhaawacmi karaa. Sidaa darteed, xabagta ayaa inta badan loo isticmaalaa in lagu xidho jajabka iyo fiilooyinka isku xidhka, samaynta "xidid jilicsan."

2.3 Tilmaamaha Farsamada

Xirmooyinka is haysta: Marka la isku daro baakadaha PCB-ga, cabbirka jajabku si weyn ayaa loo dhimi karaa, heerka isdhexgalka ayaa kordhay, naqshadaynta wareegga oo la hagaajiyay, kakanaanta wareegga oo hoos loo dhigo, iyo xasilloonida nidaamka ayaa la hagaajiyay.

Xasilooni Wanaagsan: Alxanka tooska ah ee PCB-ga waxay keenaysaa gariir wanaagsan iyo iska caabin naxdin leh, ilaalinta xasiloonida jawiyada adag sida heerkulka sare iyo qoyaanka, taas oo kordhinaysa cimriga alaabta.

Dhaqdhaqaaq Heerkuleed oo heer sare ah: Isticmaalka xabagyada kulaylka leh ee u dhexeeya chip-ka iyo PCB waxay si wax ku ool ah u wanaajisaa kala-baxa kulaylka, yaraynta kulaylka ee chip-ka iyo hagaajinta cimriga chip.

Kharashka Wax-soo-saarka hooseeya: Iyadoo aan loo baahnayn hoggaan, waxay meesha ka saartaa qaar ka mid ah hababka adag ee ku lug leh xirayaasha iyo hogaanka, yaraynta kharashka wax soo saarka. Intaa waxaa dheer, waxay u oggolaaneysaa wax soo saar otomaatig ah, hoos u dhigista qiimaha shaqada iyo hagaajinta waxtarka wax soo saarka.

2.4 taxaddar

Way adag tahay in la dayactiro: Iibka tooska ah ee chip-ka PCB-ga ayaa ka dhigaysa ka saarista chip-ka shaqsiga ama beddelka mid aan macquul ahayn, sida caadiga ah u baahan in la beddelo dhammaan PCB-ga, kordhinta kharashyada iyo dayactirka adag.

Arrimaha la isku halleyn karo: Chips-ka ku dhex jira xabagta ayaa waxyeeli kara inta lagu jiro habka saarista, taasoo keeni karta dhaawac suuf ah oo saameeya tayada wax soo saarka.

Shuruudaha Deegaanka ee Sare: Habka baakadaha COB wuxuu dalbanayaa jawi aan boodh lahayn, deegaan-free; haddii kale, heerka guuldarradu wuu kordhaa.

3. Isbarbardhigga SMD iyo COB

Haddaba, maxay ku kala duwan yihiin labadan tignoolajiyada?

3.1 Isbarbardhigga Khibradda Aragga

Bandhigyada COB, oo leh sifooyinkooda isha iftiinka, waxay siiyaan daawadayaasha khibrado muuqaal ah oo qurux badan oo isku mid ah. Marka la barbardhigo isha isha iftiinka ee SMD, COB waxay bixisaa midabyo badan oo muuqda iyo maarayn tafatiran oo ka sii fiican, taasoo ka dhigaysa mid ku habboon muddada dheer, daawashada dhow.

3.2 Isbarbardhigga Deganaanshaha iyo Joogteynta

Iyadoo bandhigyada SMD ay fududahay in la dayactiro goobta, waxay leeyihiin difaac guud oo daciif ah waxayna aad ugu nugul yihiin arrimaha deegaanka. Taa bedelkeeda, bandhigyada COB, sababtoo ah naqshadooda guud ee baakadaha, waxay leeyihiin heerar ilaalin oo sarreeya, oo leh waxqabad wanaagsan oo biyuhu iyo boodh celin ah. Si kastaba ha ahaatee, waa in la ogaadaa in bandhigyada COB ay inta badan u baahan yihiin in lagu celiyo warshadda si loo dayactiro haddii ay dhacdo cillad.

3.3 Isticmaalka Korontada iyo Waxtarka Tamarta

Iyadoo la raacayo habka rogrogga-chip-ka ee aan la daboolin, COB waxay leedahay waxtarka ilaha iftiinka sare, taasoo keentay isticmaalka tamarta hoose ee dhalaalka isku midka ah, badbaadinta isticmaalayaasha kharashka korontada.

3.4 Qiimaha iyo Horumarinta

Tiknoolajiyada baakadaha SMD ayaa si weyn loo isticmaalaa sababtoo ah qaan-gaarnimadeeda sare iyo qiimaha wax soo saarka hooseeya. In kasta oo tignoolajiyada COB aragti ahaan ay leedahay kharashyo hoose, habraaceeda wax-soo-saarka adag iyo heerka wax-soo-saarka hooseeya ayaa hadda keenaya kharashyo dhab ah oo sarreeya. Si kastaba ha noqotee, marka tignoolajiyada ay horumarto iyo awoodda wax soo saarku ay sii ballaarato, qiimaha COB ayaa la filayaa inuu sii yaraan doono.

4. Isbeddellada Horumarineed ee Mustaqbalka

RTLED waa hormuudka tignoolajiyada bandhiga COB LED. OurCOB LED bandhigyadasi weyn ayaa loo isticmaalaa gudahadhammaan noocyada kala duwan ee bandhigyada LED ganacsiiyadoo ay ugu wacan tahay saameyntooda bandhigeed ee wanaagsan iyo waxqabad la isku halayn karo. RTLED waxaa ka go'an in ay bixiso tayo sare leh, xalal bandhig hal-joojin ah si ay u daboolaan baahiyaha macaamiisheena ee bandhigyada qeexan sare iyo tamarta-badbaadinta iyo ilaalinta deegaanka. Waxaan sii wadeynaa inaan wanaajino tignoolajiyada baakadaha COB si aan u keenno macaamiisheenna alaabooyin tartan badan annagoo horumarinayna waxtarka isha iftiinka iyo yareynta kharashka wax soo saarka. Shaashadayada COB LED kaliya maaha inay leedahay saameyn muuqaal ah oo heer sare ah iyo xasillooni sare, laakiin sidoo kale waxay si deggan ugu shaqeyn kartaa deegaanno kala duwan oo adag, taasoo siinaysa isticmaaleyaasha khibrad waara.

Suuqa soo bandhigida LED-ga ganacsiga, COB iyo SMD labaduba waxay leeyihiin faa'iidooyin u gaar ah. Iyada oo ay sii kordheyso baahida loo qabo bandhigyo qeexitaan sare leh, alaabada soo bandhigta Micro LED ee leh cufnaanta pixel sare waxay si tartiib tartiib ah u helayaan suuqa. Tiknoolajiyada COB, oo leh sifooyinkeeda baakad aad u isku dhafan, waxay noqotay tignoolajiyada muhiimka ah ee lagu gaaro cufnaanta pixel sare ee Micro LEDs. Isla mar ahaantaana, marka xajmiga pixel ee muraayadaha LED ay sii wadaan hoos u dhaca, faa'iidada kharashka tiknoolajiyada COB ayaa sii muuqda.
