Drop-In Termination (eo hape e tsejoang e le surface-mount termination resistor) ke karolo ea "surface-mount" ea theknoloji (SMT) e etselitsoeng li-circuits tsa dijithale tse lebelo le holimo le maqhubu a seea-le-moea (RF). Morero oa eona oa mantlha ke ho hatella ponts'o ea lets'oao le ho netefatsa botšepehi ba matšoao (SI). Sebakeng sa ho hokahanngoa ka lithapo, e "kenyellelitsoe" kapa "e theotsoe" ka kotloloho libakeng tse ikhethileng ho lithapo tsa phetiso tsa PCB (joalo ka mela ea microstrip), e sebetsa joalo ka mohanyetsi o ts'oanang oa ho emisa. Ke karolo ea bohlokoa ho rarolleng litaba tsa boleng ba mats'oao a lebelo le phahameng 'me e sebelisoa haholo lihlahisoa tse fapaneng tse kentsoeng, ho tloha ho li-server tsa khomphutha ho isa meahong ea likhokahano.

Litšobotsi:

1. Ts'ebetso e ikhethang ea maqhubu a phahameng le ho bapisa ho nepahetseng ha impedance
Ultra-Low parasitic inductance (ESL): Ho sebelisa meaho e emeng e holimo le mahlale a tsoetseng pele a thepa (joalo ka thekenoloji ea filimi e tšesaane), inductance ea parasitic e fokotsehile (ka tloaelo litekanyetso tse nepahetseng tsa ho hanyetsa: E fana ka litekanyetso tse nepahetseng le tse tsitsitseng tsa ho hanyetsa), ho netefatsa hore ho emisa ho emisa ho lumellana hantle le semelo, 5. 75Ω, 100Ω), e holisa ho monya matla a lets'oao le ho thibela ponahalo.
Karabelo e ntle ea khafetsa: E boloka litšoaneleho tse tsitsitseng tsa khanyetso ho feta mefuta e mengata ea maqhubu, e fetang hole hole ea setso ea axial kapa radial lead resistors.
2. Moralo oa meralo o tsoaletsoeng ho kopanya PCB
Mohaho o ikhethang o otlolohileng: Phallo ea hona joale ke perpendicular ho boto ea PCB. Li-electrode tse peli li ka holim'a bokaholimo le botlaaseng ba karolo, e hokahane ka kotloloho le lera la tšepe la phetiso le lera la fatše, ho etsa tsela e khuts'oane ea hajoale le ho fokotsa haholo inductance ea loop e bakiloeng ke mehala e telele ea li-resistars.
Theknoloji e tloaelehileng ea holim'a metsi (SMT): E lumellana le mekhoa ea kopano e ikemetseng, e loketseng tlhahiso e kholo, ho ntlafatsa ts'ebetso le botsitso.
Ho boloka sepakapaka le ho boloka sebaka: Boholo ba liphutheloana tse nyane (mohlala, 0402, 0603, 0805) bo boloka sebaka sa bohlokoa sa PCB, se etsa hore e be se loketseng bakeng sa meralo ea boto e phahameng haholo.
3. Ho sebetsana le matla a phahameng le ho tšepahala
Ho senya matla ka katleho: Ho sa tsotellehe boholo ba eona bo fokolang, moralo o ikarabella bakeng sa ho senya matla, ho o nolofalletsa ho sebetsana le mocheso o hlahisoang nakong ea ho felisoa ha pontšo ka lebelo le phahameng. Litekanyetso tse ngata tsa matla li fumaneha (mohlala, 1/16W, 1/10W, 1/8W, 1/4W).
Botšepehi bo phahameng le botsitso: E sebelisa lisebelisoa tse tsitsitseng le meaho e tiileng, e fanang ka matla a matla a mochini, ho hanyetsa mocheso oa mocheso, le ho ts'epahala ha nako e telele, ho etsa hore e tšoanelehe bakeng sa lits'ebetso tse hlokang indasteri.

Lisebelisoa:

1. Ho felisoa ha libese tsa digital tsa lebelo le phahameng
Libeseng tse tsamaeang ka lebelo le holimo (mohlala, DDR4, DDR5 SDRAM) le libese tse fapaneng, moo litefiso tsa phetisetso ea mats'oao li leng holimo haholo, li-resistors tsa Drop-In Termination li beoa qetellong ea mohala oa phetisetso (ho felisoa) kapa mohloling (ho felisoa ha mohloli). Sena se fana ka tsela e fokolang ea motlakase kapa fatše, e monyang matla a pontšo ha e fihla, ka tsela eo e felisa ho bonahatsa, ho hloekisa maqhubu a maqhubu a maqhubu, le ho netefatsa phetiso e tsitsitseng ea data. Ena ke ts'ebeliso ea eona ea khale ka ho fetesisa le e atileng ho li-module tsa memori (DIMMs) le meralo ea liboto tsa bo-mme.
2. Lipotoloho tsa RF le microwave
Ka lisebelisoa tsa puisano tse se nang mohala, lits'ebetso tsa radar, lisebelisoa tsa liteko, le lits'ebetso tse ling tsa RF, Drop-In Termination e sebelisoa e le mojaro o ts'oanang ho tlhahiso ea likhahla tsa motlakase, li-couplers le amplifiers. E fana ka tšitiso e tloaelehileng ea 50Ω, e monya matla a RF a feteletseng, e ntlafatsa ho itšehla thajana, e fokotsa liphoso tsa ho lekanya, le ho thibela ponahalo ea matla ho sireletsa likarolo tsa RF tse hlokolosi le ho netefatsa ts'ebetso ea sistimi.
3. Li-interface tsa serial tsa lebelo le phahameng
Maemong ao ho ona wiring ea boemo ba boto e leng telele kapa topology e rarahane, joalo ka PCIe, SATA, SAS, USB 3.0+, le lihokelo tse ling tsa serial tse lebelo le holimo tse nang le litlhoko tse thata tsa boleng ba matšoao, Drop-In Termination ea boleng bo holimo e sebelisoa bakeng sa papali e ntlafalitsoeng.
4. Lisebelisoa tsa marang-rang le tsa puisano
Ho li-routers, li-switches, optical modules, le lisebelisoa tse ling, moo melapo ea lebelo le phahameng ho lifofane tse ka morao (mohlala, 25G +) e hloka taolo e thata ea ho thibela ho thibela, Drop-In Termination e sebelisoa haufi le li-connectors tsa backplane kapa lipheletsong tsa mela e telele ea phetisetso ho ntlafatsa botšepehi ba matšoao le ho fokotsa sekhahla sa phoso (BER).

Qualwavephepelo Dorp-In Terminations koahela frequency range DC ~ 3GHz. Ka karolelano matla a ts'oaroang ke li-watts tse 100.
