Yuav ua li cas PCB Connector Pitch Tolerances cuam tshuam rau kev ncaj ncees ntawm cov teeb liab hauv cov ntawv thov zaus siab
TL;DR — Cov Ntsiab Lus Tseem Ceeb
- Qhov kev kam rau ntawm lub suab ntawm lub connector ncaj qha txiav txim siab qhov tseeb ntawm cov teeb liab ntawm cov zaus siab. Yog tias qhov sib txawv ntawm +/- 0.05 hli, nws tuaj yeem hloov qhov impedance ntawm 5-12 ohms, ua rau muaj qhov cuam tshuam ntawm cov teeb liab thiab cov ntaub ntawv yuam kev.
- Rau cov ntawv thov siab dua 1 GHz, qhia meej qhov kev kam rau siab ntawm +/- 0.05mm lossis zoo dua. Cov khoom sib txuas txheem +/- 0.1mm kev kam rau siab tsuas yog txwv rau kev ua haujlwm qis dua 500 MHz.
- Kev xaiv cov khoom siv yog qhov tseem ceeb: LCP dielectrics txuas ntxiv cov kev txwv zaus siv tau los ntawm 30-50% dhau ntawm tus qauv PA66 / PA6T connectors ntawm tib lub suab.
- NBJGE IC Socket series muaj peb qhov sib txawv ntawm lub suab (1.27mm, 2.0mm, 2.54mm) nrog kev ua kom raug rau kev sib txuas lus, kev tswj hwm kev lag luam, thiab kev siv RF.
Kev kam rau siab ntawm lub suab ntawm PCB connector yog ib qho ntawm cov kev ntsuas tseem ceeb tshaj plaws uas txiav txim siab qhov kev ncaj ncees ntawm lub teeb liab hauv cov kab ke hluav taws xob siab. Thaum lub sijhawm nce teeb liab mus txog 1 nanosecond lossis qis dua, qhov ntev ntawm lub qhov txuas ntawm lub qhov txuas pib tswj hwm tus cwj pwm hluav taws xob. Cov kws tsim qauv xaiv cov khoom txuas rau kev sib txuas lus cov khoom siv hauv paus, cov tshuab tswj kev lag luam, lossis RF modules tsis tuaj yeem kho qhov kev kam rau siab ntawm lub suab ua qhov kev qhia thib ob.
Vim tias txawm tias qhov sib txawv me me ntawm qhov sib nrug ntawm kev sib cuag-rau-kev sib cuag tsim cov impedance discontinuities uas cuam tshuam lub zog rov qab mus rau qhov chaw es tsis yog xa nws mus rau qhov thauj khoom. Hauv lub kaw lus 50 ohm ua haujlwm ntawm 2.4 GHz, ib qho kev kam rau siab ntawm lub suab qis ntawm tsuas yog 10 ohms tuaj yeem tsim qhov voltage sawv nthwv dej piv (VSWR) ntau dua 1.5: 1, ua rau muaj 4% poob zog uas sib xyaw ua ke thoob plaws ntau lub interfaces txuas.
Nkag Siab Txog Qhov Sib Txuas PCB thiab Nws Lub Luag Haujlwm Hauv Kev Xa Xov Tooj
Qhov sib txuas - lub qhov nruab nrab ntawm qhov chaw nruab nrab ntawm cov neeg sib cuag nyob ib sab hauv PCB connector lossis IC socket — txhais cov qauv tseem ceeb ntawm txoj kev sib kis. Qhov ntsuas no, ua ke nrog cov khoom siv dielectric thiab kev sib cuag geometry, tsim kom muaj tus yam ntxwv impedance (Z0) uas lub teeb liab tau ntsib thaum nws mus ncig los ntawm lub connector.
Hauv kev tsim PCB siab zaus, lub hom phiaj yog kom muaj qhov impedance sib xws thoob plaws hauv txoj kev teeb liab los ntawm tus tsav tsheb mus rau tus txais. Txhua qhov kev hloov pauv sai sai hauv impedance tsim ib feem ntawm kev cuam tshuam. Lub zog cuam tshuam rho tawm ntawm lub teeb liab mus tom ntej, txo qhov amplitude ntawm lub receiver thiab tej zaum yuav ua rau muaj qhov yuam kev me ntsis hauv cov kab ke digital.
Qhov kev sib raug zoo ntawm qhov sib txuas ntawm lub suab thiab impedance ua raws li txoj kev xav ntawm txoj kab xa xov uas tau tsim tsa zoo. Lub suab dav dua feem ntau ua rau muaj impedance siab dua rau ib qho geometry ntawm kev sib cuag, thaum lub suab nqaim dua txo qhov impedance los ntawm kev nce qhov kev sib txuas capacitive ntawm cov neeg sib txuas.
Vim Li Cas Kev Ua Siab Ntev ntawm Pitch Yog Qhov Tseem Ceeb Tshaj Plaws - Tsis Yog Pitch Xwb
Cov nqi suab nominal (2.54mm, 2.0mm, 1.27mm) muab cov qauv geometry uas koj xav tau, tab sis kev kam rau kev tsim khoom txiav txim siab seb cov qauv geometry ntawd puas ruaj khov li cas thoob plaws cov ntim khoom. Ib qho txuas uas tau teev tseg ntawm 2.54 hli suab tab sis tsim nrog +/- 0.15 hli kev kam rau siab yuav ua rau muaj kev hloov pauv tseem ceeb hauv impedance los ntawm tus pin mus rau tus pin thiab los ntawm ib pawg mus rau ib pawg.
Vim tias impedance yog inversely proportional rau qhov sib nrug ntawm cov teeb liab thiab cov neeg xa rov qab, qhov sib txawv +/- 0.1 hli hauv lub suab tuaj yeem tsim qhov sib txawv impedance ntawm +/- 4 txog +/- 8 ohms hauv qhov kev teeb tsa 50 ohm microstrip. Thaum qhov kev hloov pauv no ncav cuag +/- 12 ohms lossis ntau dua - feem ntau nrog cov khoom siv sib txuas hauv qib pheej yig - qhov kev tsis sib txuas ntawm impedance dhau los ua qhov hnyav txaus kom ua rau lub teeb liab tsis zoo txawm tias nyob rau ntawm qhov zaus nruab nrab.
| Kev kam rau siab (+/- hli) | Kev hloov pauv impedance (+/- ohms) | Zaus Siv Tau Ntau Tshaj Plaws (GHz) | Daim Ntawv Thov Ib Txwm Muaj |
|---|---|---|---|
| +/-0.15 | 8-12 | 0.3 | I/O ceev qis, cov khoom siv fais fab |
| +/-0.10 | 5-8 | 0.8 | Lub teeb liab dav dav, kev tswj hwm kev lag luam |
| +/-0.05 | 3-5 | 3.0 | Gigabit Ethernet, daim npav kab xov tooj |
| +/-0.03 | 1-3 | 10.0 | Cov modules RF, 5G infrastructure |
Qhov no yog vim li cas qhov kev teev tseg qhov kev kam rau siab sib cais cov qauv tsim loj heev los ntawm cov kev qhia txog kev nyiam ua si. Qhov +/- 0.05mm kev kam rau siab muaj nyob rau hauv NBJGE precision IC sockets sawv cev rau qhov kev siv tau zoo rau kev ua haujlwm txhim khu kev qha saum 1 GHz.
Kev Sib Piv ntawm IC Socket Pitch: 1.27mm vs 2.0mm vs 2.54mm
NBJGE cov khoom lag luam IC socket npog peb qhov sib txawv ntawm cov suab nrov, txhua qhov tau tsim kho rau ntau qhov chaw thov siab. Raws li kev ntsuas TDR ntawm lub Hoobkas uas tau ua nyob rau hauv Q1 2026 thoob plaws 200+ cov qauv, qhov kev sib piv hauv qab no qhia txog cov kev ntsuas kev ncaj ncees ntawm cov teeb liab rau txhua chav kawm suab.
| Cov Qauv | 1.27 hli Suab | 2.0 hli Suab | 2.54 hli Suab |
|---|---|---|---|
| Kev kam rau siab tus qauv | +/-0.05 hli | +/-0.05 hli | +/-0.10 hli (standd) / +/-0.05 hli (premium) |
| Yam ntxwv Impedance | 42 +/- 5 ohms | 48 +/- 4 ohms | 52 +/- 5 ohms |
| Kev Poob Ntxig (ntawm 3 GHz) | -0.8 dB | -0.6 dB | -0.5 dB |
| Crosstalk (ntawm 2 GHz, cov pins sib ze) | -22 dB | -28 dB | -32 dB |
| Bandwidth Siv Tau (-3 dB) | 2.5 GHz | 4.0 GHz | 5.5 GHz |
| Qhov Ceev ntawm Pin (pins ib cm2) | 62 | 25 | 15 |
| Daim Ntawv Thov Zoo Tshaj Plaws | Lub tsheb npav digital ceev ceev | Cov kab ke sib xyaw ua ke | RF / high-zaus analog |
Peb cov kev ntsuas qhia tau tias muaj kev lag luam meej: lub suab me dua muab cov pin density siab dua tab sis qhia txog crosstalk siab dua thiab impedance qis dua, ob qho tib si ua rau kev ua haujlwm siab poob qis. Qhov 2.54 hli suab variant, nrog nws cov crosstalk qis dua (-32 dB vs -22 dB rau 1.27 hli) thiab phim ze dua rau 50 ohm system impedance, ua tau zoo dua cov khoom sib txuas zoo dua hauv cov ntawv thov analog RF saum toj no 1 GHz.
Qhov no yog ib qho kev nkag siab tseem ceeb rau cov kws tsim qauv: thaum lub teeb liab zoo yog qhov tseem ceeb, tsis txhob hloov mus rau qhov me tshaj plaws tsuas yog kom txuag tau qhov chaw. Lub qhov (socket) IC 2.54mm pitch tseem yog qhov kev xaiv zoo tshaj plaws rau feem ntau ntawm RF thiab kev sib txuas lus txog li 5 GHz.
Yuav Ua Li Cas Kev Tsim Khoom Siv Tsim Kev Tsis Sib Txuas Lus Impedance

Lub hauv paus ua rau muaj qhov teeb meem #1: Vim tias qhov yuam kev ntawm qhov chaw sib cuag thaum lub sijhawm molding thiab cov txheej txheem ntxig ua rau muaj qhov sib nrug tsis sib xws ntawm cov teeb liab sib txuas, qhov capacitance ib chav ntev hloov ntawm tus pin mus rau tus pin. Qhov kev hloov pauv capacitance hauv zos no ua rau muaj kev hloov pauv impedance sib xws ntawm txhua qhov chaw sib txuas. Ntawm 2.4 GHz, qhov yuam kev ntawm 0.08 hli ntawm ob tus pin sib txuas ua rau muaj kev hloov pauv capacitance kwv yees li 0.15 pF, uas nyob rau hauv lub kaw lus 50 ohm sib raug rau qib impedance ntawm 7 ohms.
Lub hauv paus ua rau muaj #2: Vim tias cov khoom siv rwb thaiv tsev (feem ntau yog PA66, PA6T, lossis LCP) raug txo qis 0.2-1.5% thaum lub sijhawm txhaj tshuaj molding txias, qhov sib nrug ntawm qhov sib cuag tom qab txias txawv ntawm qhov tsim pwm. Lub qhov txuas 2.54mm pitch molded hauv PA6T nrog 0.6% pwm shrinkage muaj qhov nruab nrab txo qis ntawm 0.015mm. Thaum ua ke nrog kev hnav cov cuab yeej, kev hloov pauv kub, thiab kev hloov pauv ntawm cov khoom siv, kev kam rau siab tuaj yeem ncav cuag 0.10-0.15mm.
