Mabone a shoeleng a LED ke Guan Jian, a amang bongata ba tlhahiso le ho tšepahala. Mokhoa oa ho fokotsa le ho felisa mabone a shoeleng le ho eketsa molumo oa tlhahiso le ho tšepahala ke taba ea bohlokoa e lokelang ho sebetsanoa le ho tiisa le ho sebelisa likhoebo. Ha re etse tlhahlobo le lipuisano mabapi le ho etsoa ha mabone a shoeleng. 1. Tšenyo ea motlakase ho chip ea LED e senyehile ho etsa hore lefito la PN la chip ea LED le nyamele, hona joale ho lutla hoa hlakoloa, 'me e fetoha mofuta oa khanyetso. It is a very harmful devil. Mashome a limilione tsa lidolara tsa tahlehelo ea moruo. Ka hona, karolo ea elektroniki ea karolo ea elektronike ea anti-line ke mosebetsi oa bohlokoa haholo indastering ea lisebelisoa tsa elektroniki. Se ke oa e nka habobebe bakeng sa lik'hamphani tsa ho paka tsa LED le likhamphani tse bonts'ang tsa LED. Haeba ho na le bothata ho sehokelo sefe kapa sefe, se tla baka tšenyo ho LED, e leng se tla etsa hore ts'ebetso ea LED e senyehe. Rea tseba hore 'mele oa motho (ESD) o ka fihla li-volt tse likete tse tharo ka ho le letšehali,' me maoto a ka senya chip ea LED ka tšenyo. Ke ho paka mela ea tlhahiso ho LED. Hore na ho hanyetsa fatše ha lisebelisoa tse fapaneng ho ka finyella litlhoko. It is also very important. Generally, ground resistance is required For 4 ohms, the ground resistance is not required to reach≤2 ohm. Tšenyo ea LED ea 'mele oa motho le eona e kholo haholo. Ha u sebetsa, ho roala junifomo ea anti-static, e nang le selikalikoe sa motlakase se tsitsitseng, selikalikoe sa static electrostatic ke pontšo e mpe, 'me ha ho na phello e ntle ho potoloha ha motlakase oa lesale la electrostatic. Haeba u sa sebelise mofuta ona oa sehlahisoa, haeba basebetsi ba tlōla mekhoa ea ts'ebetso, ba lokela ho fumana thuto e ngata ea temoso, 'me ka nako e ts'oanang, e khothalletsa tšebeliso ea ba bang. Ke bokae 'mele oa motho o nang le motlakase o tsitsitseng, liaparo tse fapaneng tsa lesela tse aparoang ke batho, le molumo oa motho e mong le e mong, bosiung ba hoetla le mariha, re thatafalloa ho bona ho tsoa pakeng tsa liaparo. Vile. Boleng ba ESD ba silicon-based base chip ke li-volts tse 1100 feela, 'me boleng ba ESD ba chip ea safire bo tlase, ha feela. 500 —600 volts. Chip e ntle kapa LED, haeba re e nka ka matsoho ('mele ha o nke mehato leha e le efe e sireletsang), liphello li ka nahanoa hore chip kapa LED e tla senyeha ka likhato tse sa tšoaneng. Letsoho le monate hoo le leng le letle hoo ke seoa sa motlakase o tsitsitseng. Haeba khoebo ea ho paka e sa sebetse ka thata ho latela melao ea mobu, ke k'hamphani ka boeona e tla fokotsa sekhahla sa boleng ba sehlahisoa le ho fokotsa bonnete ba moruo oa khoebo. Haeba lisebelisoa le basebetsi ba sebelisang li-LED li sa theohe, ho ke ke ha qojoa. Ho ea ka litlhoko tsa bukana e tloaelehileng ea LED, colloid ea sebaka sa pele sa LED ha se ka tlase ho 3 —5 mm, bending or welding, but most of the companies do not do that, but only the thickness of a PCB board (≤2 mm) indirect welding, which will also cause damage or damage to LEDs. Hobane mocheso o feteletseng oa welding o tla ama chip, o tla senya litšobotsi tsa chip le ho fokotsa bokhoni ba mabone, e le hore ketsahalo eo e se e sa tloaelehang. Ha ho na khoebo e nyane e sebelisang welding ka letsoho, e sebelisa tšepe ea solder ea 40 wattipaton, mocheso oa welding o ke ke oa laoloa, 'me mocheso oa tšepe oa soldering o teng. 300 —Ka holimo ho 400 C, mocheso o phahameng haholo oa welding o tla boela o thehe mabone a shoeleng. Leseli la LED le phahame ka makhetlo a 'maloa ho feta coefficient ea ho ruruha ho 150 C mocheso o phahameng. Ho bata ho honyetsa ntlha ea tjheseletsa e bulehile, ho etsa lebone le shweleng. 2. Lebaka la ts'ebetso ea ts'ebetso ea lebone ka har'a khokahano e ka hare ea mabone a LeD. 2.1 Tlhahlobo ea ts'ebetso ea mabone a shoeleng 2.1 Ts'ebetso ea tlhahiso ea khoebo ea liphutheloana ha e e-s'o phethehe, 'me mokhoa oa ho hlahloba o morao. Mohala o koalang o entsoe ka lisebelisoa tsa tšepe tsa koporo kapa tsa tšepe ka liforomo tse nepahetseng. Hobane thepa ea koporo e theko e boima haholo, litšenyehelo li phahame ka tlhaho. Ka lebaka la 'maraka o bohale, lintlha li ameha. Steel brings stamping LEDs. Ho koaloa ha tšepe ea tšepe e tlameha ho ba silevera - e koahetsoeng. Ho roala silevera ha ho na liphello tse peli. E 'ngoe ke ho thibela moxibustion le mafome. E 'ngoe ke ho nolofatsa welding. E amana le bophelo ba LED.
