HADDA LA XIRIIR

Joojinta Joojinta (sidoo kale loo yaqaan resistor-ka-saarista dusha sare) waa tignoolajiyada dusha sare leh (SMT) qayb gaar ah oo loogu talagalay wareegyada xawaaraha sare ee dhijitaalka ah iyo wareegyada soo noqnoqda raadiyaha (RF). Hadafkeeda udub-dhexaadka ah waa in la xakameeyo milicsiga calaamadaha iyo in la hubiyo daacadnimada calaamadaha (SI). Halkii lagu xidhi lahaa fiilooyin, si toos ah ayaa loo "ku-xidhan yahay" ama "lagu ridaa" meelo gaar ah oo ku yaal xadadka gudbinta PCB (sida khadadka microstrip), oo u dhaqmaya sidii iska caabiyaha joojinta barbar socda. Waa qayb muhiim u ah xallinta arrimaha tayada calaamadaha xawaaraha sare leh waxaana si weyn loogu isticmaalaa alaabooyin kala duwan oo ku xiran, laga soo bilaabo server-yada kumbuyuutarka ilaa kaabayaasha isgaarsiinta.

Astaamaha:

1. Waxqabadka soo noqnoqda sare ee gaarka ah iyo isbarbardhigga saxda ah ee saxda ah
Inductance Parasitic Ultra-Low (ESL): Isticmaalka qaab-dhismeedka toosan ee hal-abuurka leh iyo teknoolojiyadda agabka horumarsan (sida tignoolajiyada-filimka-dhuuban), inductance-ka ayaa la yareeyaa (qiimaha iska caabbinta caadiga ah: Waxay bixisaa qiimeyaal iska caabin heer sare ah oo sax ah oo xasilloon), iyadoo la hubinayo in xannibaadda joojinta si sax ah ay u dhiganto cilladda dabeecadda ee xariiqda gudbinta, 75ΩΩΩΩ 100Ω), kordhinta nuugista tamarta signalka iyo ka hortagga milicsiga.
Jawaab celin joogto ah oo heer sare ah: Waxay ilaalisaa sifooyin caabbinta deggan oo ka badan baaxadda soo noqnoqoshada ballaaran, oo aad uga sarreeya caabiyeyaasha rasaasta dhaqameed ee axial ama radial.
2. Naqshad qaabdhismeed u dhashay is dhexgalka PCB
Qaab dhismeed toosan oo gaar ah: Socodka hadda socdaa wuxuu ku siman yahay dusha guddiga PCB. Labada electrodes waxay ku yaalaan dusha sare iyo hoose ee qaybta, oo si toos ah ugu xiran lakabka birta ee xariiqda gudbinta iyo lakabka dhulka, samaynta dariiqa ugu gaaban ee hadda jira waxayna si weyn u yareeyaan inductance loop oo ay keento caabiyeyaasha dhaqameed ee dheereeya.
Tiknoolajiyada caadiga ah ee dusha sare (SMT): La jaan qaada hababka isku-dhafka otomaatiga ah, oo ku habboon wax soo saarka ballaaran, hagaajinta waxtarka iyo joogtaynta.
Is haysta iyo meel-badbaadinta: Cabbirrada xirmooyinka yaryar (tusaale, 0402, 0603, 0805) waxay badbaadiyaan booska PCB ee qiimaha leh, taasoo ka dhigaysa mid ku habboon naqshadaha guddiga cufnaanta sare.
3. Maaraynta awoodda sare iyo isku halaynta
Koronto wax ku ool ah: Inkasta oo ay yar tahay, naqshadeynta ayaa xisaabinaysa korontadu, taas oo u oggolaanaysa inay xakameyso kulaylka soo baxa inta lagu jiro joojinta xawaaraha sare. Qiimayn koronto oo badan ayaa diyaar ah (tusaale, 1/16W, 1/10W, 1/8W, 1/4W).
Kalsoonida sare iyo xasiloonida: Shaqaalaysiiya nidaamyada walxaha xasilan iyo dhismayaal adag, oo bixiya awood farsamo oo heer sare ah, iska caabinta shoogga kulaylka, iyo isku halaynta muddada dheer, taas oo ka dhigaysa mid ku habboon dalabaadka codsiyada warshadaha.

Codsiyada:

1. Joojinta basaska xawaaraha sare leh
Basaska isku midka ah ee xawaaraha sare leh (tusaale, DDR4, DDR5 SDRAM) iyo basaska kala duwan, halkaasoo heerka gudbinta calaamaduhu aad u sarreeyo, iska caabiyeyaasha joojinta joojinta ayaa la dhigayaa dhammaadka khadka gudbinta (dhammaadka joojinta) ama isha (joojinta isha). Tani waxay ku siinaysaa dariiq hoose oo daciif ah xagga tamarta ama dhulka, nuugaysa tamarta signalka marka ay timaado, taas oo meesha ka saaraysa milicsiga, nadiifinta mowjadaha calaamadaha, iyo hubinta gudbinta xogta deggan. Kani waa codsigeedii ugu qadiimiga ahaa uguna baahsanaa qaybaha xusuusta (DIMM-yada) iyo naqshadaha Motherboard-ka.
2. RF iyo wareegyada microwave
Qalabka isgaadhsiinta bilaa-waayirka ah, nidaamyada radar, aaladaha tijaabada, iyo nidaamyada kale ee RF, Joojinta Joojinta waxaa loo isticmaalaa culeys isku mid ah soo saarida awood qaybiyeyaasha, lammaaneyaasha, iyo cod-weyneyaasha. Waxay bixisaa heerka 50Ω impedance, nuugista awoodda RF ee xad-dhaafka ah, hagaajinta go'doominta kanaalka, yaraynta khaladaadka cabbirka, iyo ka hortagga milicsiga tamarta si loo ilaaliyo qaybaha RF ee xasaasiga ah loona hubiyo waxqabadka nidaamka.
3. Xawaaraha-xawaaraha sare ee interfaces taxane
Xaaladaha halka fiilooyinka heerka guddiga uu dheer yahay ama topology-ga uu yahay mid adag, sida PCIe, SATA, SAS, USB 3.0+, iyo xiriiriyeyaasha kale ee xawaaraha sare leh ee leh shuruudaha tayada calaamada, tayada sare ee Dejinta-In joojinta ayaa loo isticmaalaa isku-habboon.
4. Qalabka isku xirka iyo isgaarsiinta
Router-yada, furayaasha, modules-yada indhaha, iyo qalabka kale, halkaas oo xadhkaha signalada xawaaraha sare ee diyaaradaha dhabarka (tusaale, 25G+) ay u baahan yihiin kontorool adag oo ka hortag ah, Joojinta Joojinta waxaa loo isticmaalaa meel u dhow xirayaasha diyaarada ama dhamaadka xadhkaha gudbinta dheer si kor loogu qaado daacadnimada calaamadaha loona yareeyo heerka qaladka yara (BER).

QualwaveSahayda Joojinta Dorp-In waxay daboolaysaa inta jeer ee kala duwan ee DC ~ 3GHz. Celcelis ahaan wax ka qabashada tamarta waa ilaa 100 watts.
