Ho fifala haLi-skrini tsa LEDke ntho e tloaelehileng.Kajeno, a re ke re hlahlobeng mabaka a 'maloa a ka sehloohong a ho fifala ha eona.
1. Sulfurization, chlorination, le bromination
Sekhahla sa silevera se holim'a bracket ea pontšo ea LED se tla hlahisa sulfide ea silevera ha e kopana le khase e nang le sebabole, 'me ha e kopana le chlorine e nang le naetrojene e nang le chlorine le khase ea bromine, e tla hlahisa halide ea silevera e hlakileng, e tla baka. mohloli o khanyang ho fetoha o motsho le ho hloleha.Sebabole / chlorine / bromination ea mehloli ea leseli e ka etsahala mohatong o mong le o mong oa tlhahiso, polokelo, botsofali, le tšebeliso ea mehloli ea leseli la LED le mabone.Ka mor'a hore ho fumanoe hore o na le sebabole / chlorine / bromination ka lebaka la ho fifala ha mohloli oa leseli, moreki o lokela ho khetha moralo o khethehileng oa ho tlosa sebabole ho latela sethala moo sebabole / chlorine / bromination e hlahang teng.Hajoale, merero ea ho lemoha sebabole/chlorine/bromine e qaliloeng ke Jinjian e kenyelletsa: sebabole sa lebone/chlorine/bromine (ho kenyeletsoa le tse hahelletsoeng kahare.phepelo ea motlakase), lebone sebabole/chlorine/bromine (ntle le phepelo ea motlakase e kantle), phepelo ea matla sebabole/chlorine/bromine, lintho tse thusang sebabole/chlorine/bromine, pokello ea liphutheloana tsa sebabole/chlorine/bromine, workshop ea mabone sebabole/chlorine/bromine, le reflow soldering workshop sulfur/chlorine/bromine.Ka lebaka la hore likhase tse nang le sebabole, chlorine le bromine li ka phunyeletsa ka hare ho mohloli oa leseli ka likheo tsa silicone kapa li-brackets, Jinjian e boetse e thakhotse leano la ho hlahloba moea o thibelang moea ho thusa bareki ho ntlafatsa litlhoko tsa bona bakeng sa lisebelisoa tsa mohloli oa leseli.
2. Oxidation
Silivera e sebetsana le oksijene habonolo maemong a mocheso o phahameng le mongobo, e hlahisa silver oxide e ntšo.Ka mor'a ho netefatsa hore lebaka la ho fifala ha mohloli oa leseli ke oxidation ea lera la silevera, Jin Jian o tla fana ka maikutlo a hore moreki a tsoele pele ho etsa lipatlisiso tsa moea holim'a mohloli oa leseli le lebone ho felisa tsela ea ho kenella ha mongobo.
3. Carbonization
Ho ipapisitsoe le boiphihlelo, bofokoli ba lisebelisoa tse kholo tse tšeletseng tsa mehloli ea leseli la LED (li-chips, li-brackets, sekhomaretsi se tiileng sa kristale, likhoele tsa bonding, phofo ea fluorescent le sekhomaretsi sa ho paka) le liphoso tsa ts'ebetso lits'ebetsong tse tharo tse kholo tsa ho paka (kristale e tiileng, wiring, le gluing) kaofela li ka lebisa mochesong o phahameng haholo mohloling oa leseli, tse bakang ho fifala ha lehae kapa ka kakaretso le carbonization ea mohloli oa leseli.Moralo o sa utloahaleng oa ho felloa ke mocheso oa mabone a LED, conductivity e tlase ea mocheso oa thepa ea ho qhala mocheso, moralo o sa utloahaleng oa phepelo ea motlakase, le liphoso tse ngata haholo tsa reflow soldering le tsona li ka baka carbonization ea mohloli oa leseli.Ka hona, ha Jinjian e tiisa esale pele hore lebaka la ho fifala ha mohloli oa leseli ke carbonization, e tla fana ka maikutlo a hore moreki a latele mohloli oa leseli la LED kapa tsela ea tlhahlobo ea lebone, a arole mohloli oa leseli / lebone, 'me a khetholle mohloli oa liphoso kapa khanyetso e phahameng ea mocheso.
4. Ho se lumellane ha lik'hemik'hale
Ho fifala ha mehloli ea leseli la LED ho ka boela ha bakoa ke tšilafalo ea lik'hemik'hale, 'me ketsahalo ena e ntšo e atisa ho hlaha ka mabone a tiisitsoeng a nang le moea o fokolang kapa o se nang moea.
Ha re kopana le boemo boo skrine ea pontšo ea LED e fetohang e ntšo, re ka batlisisa mabaka ka bonngoe le ho etsa liphetoho.
