Mokhoa oa ho khetholla boleng ba mabone a lebone la LED?

Ka nts'etsopele ea mahlale le theknoloji, mabone a LED a ka bonoa hohle. Kajeno ke tla u bolella mokhoa oa ho khetholla boleng ba mahlaseli a lebone la LED. Mmaraka oa leseli la LED o kopane, 'me litheko tsa lihlahisoa tse tsoang ho baetsi ba kamehla le lihlahisoa tse tsoang ho baetsi ba likopi li fapana haholo.

Re ka etsa boitsebahatso ba pele ho latela ponahalo e bonolo, 'me ha e le hantle re ka tseba hore na boleng bo botle kapa bo bobe.

E ka khetholloa haholo-holo likarolong tse latelang:

1. Sheba lihlopha tsa solder. Mabone a mabone a LED a hlahisoang ke bahlahisi ba kamehla ba mabone a LED a hlahisoa ka theknoloji ea patch ea SMT, ho sebelisoa solder paste le reflow soldering. Ka hona, manonyeletso a lebone la lebone la LED a batla a boreleli mme palo ea solder ha e kholo. Manonyeletso a solder a tloha ho FPC pad ho ea ho electrode ea LED ka sebōpeho sa arc.

2. Sheba boleng ba FPC. FPC e arotsoe ka mefuta e 'meli: koporo e apereng le koporo. Letlapa la koporo la boto e nang le koporo le ntse le hlahella. Haeba u sheba haufi-ufi, u ka e bona ho tsoa kamanong pakeng tsa pad le FPC. Koporo e pota-potiloeng e hokahane haufi-ufi le FPC 'me e ka kobeha ka boithatelo ntle le hore pad e oe. Haeba boto e entsoeng ka koporo e kobehile haholo, liphahlo li tla oa. Mocheso o feteletseng nakong ea tlhokomelo o tla boela o etse hore liphahlo li theohe.

3. Hlahloba bohloeki ba bokaholimo ba lesela la LED. Bokaholimo ba mabone a mabone a LED a hlahisoang ka theknoloji ea SMT bo hloekile haholo, ha ho na litšila kapa litšila tse bonahalang. Ho sa tsotellehe hore na bokaholimo ba lesela la lebone la LED le entsoeng ka letsoho le hloekisoa joang, matheba le mesaletsa ea ho hloekisa e tla sala.

4. Sheba sephutheloana. Li-strip tsa khanya tsa LED tse tloaelehileng li phuthetsoe ka li-anti-static reel, ka meqolong ea limithara tse 5 kapa 10, 'me li tiisitsoe ka mekotleng e thibelang boemo le mongobo. Mofuta oa copycat oa lebone la lebone la LED o sebelisa reel e nchafalitsoeng ntle le mekotla ea liphutheloana tse thibelang boemo le mongobo. Ha u shebisisa reel, u ka bona hore ho na le mesaletsa le mengoallo ka holim'a eona e setseng ha lileibole li tlosoa.

5. Sheba li-labels. Mekotla e tloaelehileng ea ho roala lebone la LED le li-reel li tla ba le mangolo a hatisitsoeng ho tsona, eseng lileibole tse hatisitsoeng.

6. Sheba lihokelo. Lithapo tsa khanya tsa kamehla tsa LED li tla tla le litaelo tsa tšebeliso le litlhaloso tse hlakileng ka har'a lebokose la liphutheloana, hape li tla hlomelloa ka lihokelo tsa lebone la LED kapa li-card holders; ha phetolelo ea copycat ea leseli la LED e se na lisebelisoa tsena ka lebokoseng la ho paka, hobane Ka mor'a moo, bahlahisi ba bang ba ntse ba ka boloka chelete.

Tlhokomeliso holim'a mabanta a mabone

1. Litlhoko tsa khanya bakeng sa li-LED li fapana ho latela liketsahalo le lihlahisoa tse fapaneng. Mohlala, haeba mabone a khaontareng ea mabenyane a LED a behiloe mabenkeleng a mang a maholo, re hloka ho ba le khanya e phahameng hore re khahle. Bakeng sa ts'ebetso e tšoanang ea mokhabiso, ho na le lihlahisoa tse fapaneng tse kang mabone a LED le likhoele tsa mabone a mebala a LED.

2. Bokhoni ba anti-static: Li-LED tse nang le bokhoni ba li-anti-static tse nang le matla a matla a anti-static li na le bophelo bo bolelele, empa theko e tla ba e phahameng. Hangata antistatic e molemo ka ho fetisisa ka holimo ho 700V.

3. Li-LED tse nang le bolelele bo tšoanang le mocheso oa 'mala li tla ba le' mala o tšoanang. Sena ke sa bohlokoa ka ho khetheha bakeng sa mabone a kopantsoeng ka bongata. Se hlahise phapang e ngata haholo ea mebala ka lebone le le leng.

4. Leakage current ke hona joale ha LED e tsamaisa motlakase ka lehlakoreng le ka morao. Re khothaletsa ho sebelisa lihlahisoa tsa LED tse nang le leakage e nyane ea hona joale.

5. Bokhoni bo sa keneleng metsi, litlhoko tsa mabone a LED a ka ntle le a ka hare a fapane.

6. Leseli le khanyang la LED le na le tšusumetso e kholo ho mabone a LED 'me le na le litlhoko tse kholo bakeng sa mabone a fapaneng. Mohlala, re khothaletsa ho sebelisa likhato tse 140-170 bakeng sa mabone a fluorescent a LED. Ha re na ho hlalosa tse ling ka botlalo mona.

7. Li-chips tsa LED li khetholla boleng ba mantlha ba li-LED. Ho na le mefuta e mengata ea li-chips tsa LED, ho kenyeletsoa tse tsoang lihlahisoa tsa kantle ho naha le tse tsoang Taiwan. Litheko tsa mefuta e fapaneng li fapana haholo.

8. Boholo ba chip ea LED bo boetse bo khetholla boleng le khanya ea LED. Ha re khetha, re leka ho khetha li-chips tse kholoanyane, empa theko e tla ba holimo ka tsela e tšoanang.
