IKGOKANE LE HONA JOALE

Ho Fela ha Drop-In (e tsejoang hape e le resistor ea ho emisa holim'a metsi) ke karolo e arohaneng ea theknoloji ea ho emisa holim'a metsi (SMT) e etselitsoeng ka ho khetheha lipotoloho tsa dijithale tse lebelo le phahameng le lipotoloho tsa maqhubu a seea-le-moea (RF). Sepheo sa eona sa mantlha ke ho thibela ponts'o ea lets'oao le ho netefatsa botšepehi ba lets'oao (SI). Ho e-na le ho hokahanngoa ka lithapo, e "kenngoa" ka kotloloho kapa "e kentsoe" libakeng tse itseng meleng ea phetisetso ea PCB (joalo ka mela ea microstrip), e sebetsang e le resistor ea ho emisa e tsamaeang ka tsela e ts'oanang. Ke karolo ea bohlokoa ho rarolleng mathata a boleng ba lets'oao le lebelo le phahameng 'me e sebelisoa haholo lihlahisoa tse fapaneng tse kenelletsoeng, ho tloha ho li-server tsa khomphutha ho ea ho meralo ea motheo ea puisano.

Litšobotsi:

1. Tshebetso e ikhethang ea maqhubu a phahameng le ho bapisa hantle impedance
Ho kenella ha likokoana-hloko ka tsela e feteletseng (ESL): Ho sebelisoa meaho e mecha e otlolohileng le mahlale a thepa a tsoetseng pele (joalo ka theknoloji ea filimi e tšesaane), ho kenella ha likokoana-hloko hoa fokotsoa (hangata boleng bo nepahetseng ba khanyetso: E fana ka boleng bo nepahetseng haholo ba khanyetso le bo tsitsitseng), ho netefatsa hore ho kenella ha ho felisoa ho tsamaellana hantle le thibelo e ikhethang ea mohala oa phetisetso (mohlala, 50Ω, 75Ω, 100Ω), ho eketsa ho monngoa ha matla a lets'oao le ho thibela ho bonahatsa.
Karabelo e ntle haholo ea maqhubu: E boloka litšobotsi tse tsitsitseng tsa khanyetso holim'a mefuta e mengata ea maqhubu, e sebetsa ho feta li-resistor tsa lead tsa axial kapa radial tse tloaelehileng.
2. Moralo oa sebopeho o tsoaletsoeng kopanyo ea PCB
Sebopeho se ikhethang se otlolohileng: Phallo ea hona joale e otlolohile holim'a boto ea PCB. Li-electrode tse peli li fumaneha holim'a bokaholimo ba karolo e ka holimo le e ka tlase, li hokahane ka ho toba lera la tšepe la mohala oa phetisetso le lera la fatše, li etsa tsela e khutšoanyane ka ho fetisisa ea hona joale 'me li fokotsa haholo ho kenella ha selika-likoe ho bakoang ke li-lead tse telele tsa li-resistor tsa setso.
Theknoloji e tloaelehileng ea ho kenya holim'a metsi (SMT): E lumellana le lits'ebetso tsa kopano tse iketsang, e loketse tlhahiso e kholo, e ntlafatsang bokhoni le botsitso.
E nyane ebile e boloka sebaka: Boholo ba liphutheloana tse nyane (mohlala, 0402, 0603, 0805) bo boloka sebaka sa bohlokoa sa PCB, e leng se etsang hore e be se loketseng meralo ea boto e nang le bongata bo boholo.
3. Ho sebetsana le matla a phahameng le ho tšepahala
Ho qhala ha motlakase ka katleho: Ho sa tsotellehe boholo ba wona bo bonyenyane, moralo ona o ikarabella bakeng sa ho qhala ha motlakase, o o nolofalletsang ho sebetsana le mocheso o hlahiswang nakong ya ho kgaotsa ha letshwao ka lebelo le phahameng. Ho na le ditekanyetso tse ngata tsa matla (mohlala, 1/16W, 1/10W, 1/8W, 1/4W).
Ho tšepahala le botsitso bo phahameng: E sebelisa litsamaiso tse tsitsitseng tsa thepa le meaho e matla, e fana ka matla a matle a mechini, ho hanyetsa ho thothomela ha mocheso, le ho tšepahala ha nako e telele, e leng se etsang hore e lokele lits'ebetso tse thata tsa indasteri.

Likopo:

1. Ho emisoa ha libese tsa dijithale tse lebelo le phahameng
Libeseng tse tsamaeang ka lebelo le phahameng (mohlala, DDR4, DDR5 SDRAM) le libeseng tse fapaneng, moo sekhahla sa phetisetso ea lets'oao se phahameng haholo, li-resistors tsa ho Fela ha Drop-In li beoa qetellong ea mohala oa phetisetso (qetello ea ho qetela) kapa mohloling (qetello ea mohloli). Sena se fana ka tsela e nang le impedance e tlase ho ea phepelong ea motlakase kapa fatše, e monya matla a lets'oao ha le fihla, ka hona e felisa ho bonahatsa, e hloekisa maqhubu a lets'oao, 'me e netefatsa phetisetso e tsitsitseng ea data. Ena ke ts'ebeliso ea eona ea khale ka ho fetisisa le e atileng haholo ho li-module tsa memori (DIMM) le meralo ea mamaboard.
2. Dipotoloho tsa RF le tsa microwave
Lisebelisoang tsa puisano tse se nang mohala, litsamaisong tsa radar, lisebelisoa tsa liteko, le litsamaisong tse ling tsa RF, Drop-In Termination e sebelisoa e le mojaro o lekanang tlhahisong ea li-power divider, li-couplers le li-amplifier. E fana ka impedance e tloaelehileng ea 50Ω, e monya matla a feteletseng a RF, e ntlafatsa karohano ea kanale, e fokotsa liphoso tsa tekanyo, le ho thibela ho bonahatsa matla ho sireletsa likarolo tse bonolo tsa RF le ho netefatsa ts'ebetso ea sistimi.
3. Li-interface tsa serial tse lebelo le phahameng
Maemong ao ho ona terata ya boemo ba boto e leng telele kapa topology e rarahane, jwalo ka PCIe, SATA, SAS, USB 3.0+, le dihokelo tse ding tsa serial tse potlakileng tse nang le ditlhoko tse thata tsa boleng ba letshwao, ho fediswa ha Drop-In ka ntle ho boleng bo hodimo ho sebediswa bakeng sa ho bapisa ho ntlafaditsweng.
4. Lisebelisoa tsa marangrang le puisano
Ho li-router, li-switch, li-module tsa optical, le lisebelisoa tse ling, moo mela ea matšoao a lebelo le phahameng lifolaneng tsa morao (mohlala, 25G+) e hlokang taolo e tiileng ea impedance, Drop-In Termination e sebelisoa haufi le lihokelo tsa backplane kapa lipheletsong tsa mela e melelele ea phetisetso ho ntlafatsa botšepehi ba lets'oao le ho fokotsa sekhahla sa liphoso tsa bit (BER).

QualwaveDiphepelo tsa Dorp-In Terminations di akaretsa maqhubu a DC~3GHz. Tshebetso e tloaelehileng ya matla e fihla ho di-watts tse 100.
