Li-inductors tsa matla a SMD ke e 'ngoe ea likhalase tsa tšepe tsa uranium. Common mode inductance, eo hape e tsejoang e le common mode choke, hangata e sebelisoa ho sefa mats'oao a tšitiso ea motlakase ea motlakase ho phepelo ea motlakase ea komporo. Moqaping oa boto ea potoloho, inductor ea mokhoa o tloaelehileng e boetse e sebetsa joalo ka filthara ea EMI ho hatella leqhubu la motlakase le hlahisoang ke mohala oa lebelo le phahameng ho tloha ho khanya ho ea kantle. Ke mohanyetsi o entsoeng ka motsoako oa phofo ea tšepe le phofo ea khalase ea uranium, e hatisitsoeng skrineng ho inductor ea matla a matla a SMD holim'a substrate. Ho koloba hantle, ho hanyetsa mocheso o phahameng, mocheso o tlase oa coefficient. Tšebeliso ea theknoloji ea kopano ka lebitso e 'nile ea atile haholo,' me karolo ea lihlahisoa tsa elektronike tse kopantsoeng ke SMT e fetile 90%. naha ea heso e ka be e kene litsebo tsa SMT ho tloha ka bo-1980. Ka nts'etsopele ea lisebelisoa tse nyane tsa tlhahiso ea SMT, sebaka sa ts'ebeliso ea likarolo tsa SMT se ekelitsoe le ho feta. Lifofane, sefofane, lisebelisoa, lisebelisoa tsa mochine le lihlopha tse ling le tsona li sebelisa SMT ho hlahisa lihlopha tse nyenyane tse sa tšoaneng tsa lihlahisoa tsa elektronike kapa likarolo.

Li-resistors ka bomong li bitsoa resistors bophelong ba letsatsi le letsatsi. Ntho e fokotsang hona joale e hokahaneng le mohanyetsi oa potoloho. Mohanyetsi o na le boleng bo tsitsitseng ba lithapo tse peli 'me o sebelisetsoa ho fokotsa hona joale ho phalla ka lekaleng leo e hokahaneng ho lona. Khanyetso eo boleng ba eona ba ho hanyetsa bo ke keng ba fetoloa bo bitsoa khanyetso e tsitsitseng. Ba nang le khanyetso e fapaneng ba bitsoa potentiometers kapa li-resistant tse fapaneng. Ho hanyetsa ha sebele ho na le linear, ke hore, nako ea nakoana ka ho hanyetsa e lekana le motlakase oa nakoana o sebelisoang. Resistor e feto-fetohang bakeng sa divider ea voltage. Sehokelo sa tšepe e le 'ngoe kapa tse peli tse tsamaeang, tobetsa ka thata holim'a sehanyetsi se pepesitsoeng. Boemo ba ho ikopanya bo lekanya khanyetso pakeng tsa pheletso efe kapa efe ea sehanyetsi le sehokelo.

Likarolo tsa lihlahisoa tsa baetsi ba motlakase oa SMD
Boholo bo nyane le boima bo bobebe; · E loketse bakeng sa reflow soldering le wave soldering; · Enjene e ka ba matla le ho tiea; · Theko e tlaase ea kopano, e tsamaellanang le lisebelisoa tse sebetsang tsa ho kenya; · Matla a phahameng a mochini le litšobotsi tse phahameng tsa maqhubu. Bakeng sa ho sireletsa lithapo, li-loops le li-coil ho tsoa ho matla a khoheli a kantle le ho fokotsa phello ea tšitiso ea lebala la motlakase le hlahisoang ke potoloho ho likarolo tse ling, hangata ho amoheloa mekhoa ea tšireletso ea makenete kapa ea motlakase.
Ke lisebelisoa life tse entsoeng ka li-inductors tsa motlakase tsa SMD?
Li-resistors tsa SMT li entsoe ka thoko ho data e latelang:
Thepa ea motheo ke alumina, 'me data ea ho hanyetsa ke ruthenium oxide
1. Substrate
2. Ho hanyetsa peista
3. Pheta tlhahisoleseding
4. Lintlha tse ntle tsa tataiso le lintlha tsa tataiso ea mahlakoreng
5. Tlhokomelo ea mantlha ea khalase ea G16. Tlhokomelo ea bobeli ea khalase G27.
