Tsim cov txheej txheem rau nruj-flex Circuit Court board layout

Thaum tsim lub rooj tsav xwm nruj-flex Circuit Court, ib qho ntawm cov ntsiab lus tseem ceeb uas yuav tsum tau xav txog yog txoj kab ntawm cov kab. Cov kab nyob rau ntawm lub rooj tsav xwm Circuit Court ua lub luag haujlwm tseem ceeb hauv kev ua kom muaj kev ua haujlwm zoo ntawm cov khoom siv hluav taws xob.Hauv tsab ntawv tshaj tawm no, peb yuav tham txog cov qauv tsim qauv rau kev coj ua hauv cov rooj sib dhos nruj-flex.

1. Cov kab dav dav thiab qhov sib txawv:

Qhov dav ntawm ib kab yog qhov tseem ceeb hauv kev txiav txim siab nws lub peev xwm nqa tam sim no thiab impedance. Nws raug nquahu kom siv cov kab dav dav rau kev sib txuas siab tam sim no kom tsis txhob muaj cua sov ntau dhau thiab tsis ua haujlwm. Ib yam li ntawd, qhov sib nrug ntawm cov kab yuav tsum txaus los tiv thaiv crosstalk thiab electromagnetic cuam tshuam (EMI). Cov kab dav dav thiab qhov sib txawv ntawm cov txheej txheem yuav txawv nyob ntawm seb cov kev cai tshwj xeeb ntawm lub rooj tsavxwm thiab nws cov khoom.

2. Teeb liab kev ncaj ncees thiab impedance tswj:

Lub teeb liab kev ncaj ncees yog ib qho tseem ceeb rau kev txiav txim siab hauv Circuit Board tsim. Rigid-flex boards feem ntau muaj cov khoom sib txawv nrog cov kev cai impedance, xws li microstrip thiab stripline kis kab. Nws yog ib qho tseem ceeb kom tswj tau qhov impedance txuam thoob plaws hauv cov txheej txheem routing kom txo cov teeb liab cuam tshuam thiab ua kom pom kev ua haujlwm zoo. Cov cuab yeej xws li lub laij lej impedance thiab simulation software tuaj yeem pab ua tiav qhov kev tswj hwm impedance.

3. Txheej stacking thiab hloov tau yooj yim khoov thaj chaw:

Rigid-flex circuit boards feem ntau yog tsim los ntawm ntau txheej, nrog rau cov khoom tsis sib xws thiab cov khoom siv tau yooj yim. Qhov kev teeb tsa thiab kev sib txuas ntawm cov kab sib txawv ntawm cov khaubncaws sab nraud povtseg yuav tsum tau ua tib zoo txiav txim siab kom tsis txhob muaj teeb meem cuam tshuam thiab tswj lub rooj tsavxwm yooj. Nws yog ib qho tsim nyog los txheeb xyuas cov cheeb tsam uas lub rooj tsavxwm yuav khoov thiab tsis txhob muab cov cim tseem ceeb hauv cov cheeb tsam no, vim tias kev khoov ntau dhau yuav ua rau cov kab tawg lossis tsis ua haujlwm.

4. Differential khub routing:

Hauv kev tsim hluav taws xob niaj hnub no, cov khub sib txawv feem ntau siv rau cov teeb liab ceev kom ntseeg tau cov ntaub ntawv xa mus. Thaum routing sib txawv khub hauv rigid-flex boards, nws yog ib qho tseem ceeb kom tswj tau qhov ntev thiab qhov sib txawv ntawm cov kab sib txawv kom tswj tau cov teeb liab kev ncaj ncees. Txhua qhov kev tsis sib haum xeeb tuaj yeem ua rau lub sijhawm yuam kev lossis teeb liab distortion, cuam tshuam rau tag nrho kev ua haujlwm ntawm lub voj voog.

5. Los ntawm layout thiab kiv cua tawm:

Vias yog ib qho tseem ceeb hauv kev tsim Circuit Court board vim lawv muab kev sib txuas hluav taws xob ntawm cov txheej txheem sib txawv. Tsim nyog los ntawm kev teeb tsa thiab cov kiv cua tawm tswv yim pab tswj cov teeb liab kev ncaj ncees thiab ua kom muaj kev sib txuas txhim khu kev qha. Nws yog ib qho tseem ceeb kom tsis txhob tso cov vias ze ze rau cov kab nrawm nrawm vim tias lawv yuav qhia txog kev cuam tshuam los yog impedance tsis sib haum.

6. EMI thiab Grounding:

Electromagnetic cuam tshuam (EMI) tuaj yeem cuam tshuam tsis zoo rau kev ua haujlwm ntawm cov khoom siv hluav taws xob. Txhawm rau txo qis EMI, nco ntsoov ua tib zoo mloog rau cov txheej txheem hauv av thiab ua tib zoo txoj kev xaim nyob ze ntawm cov khoom rhiab. Lub dav hlau hauv av tuaj yeem ua raws li daim thaiv thiab txo EMI. Los ntawm kev ua kom cov txheej txheem hauv av kom zoo, lub suab nrov thiab kev sib tham tuaj yeem raug txo qis, yog li txhim kho kev ua tau zoo tag nrho.

Hauv Summary

Tsim ib lub rooj tsavxwm nruj-flex Circuit Court yuav tsum tau ua tib zoo xav txog ntau yam, thiab txoj kev taug kev yog ib qho tseem ceeb uas cuam tshuam rau tag nrho kev ua haujlwm thiab kev ntseeg siab ntawm lub voj voog. Los ntawm kev ua raws li cov txheej txheem tsim qauv sib tham hauv tsab ntawv tshaj tawm no, cov kws tshaj lij tuaj yeem ua kom pom cov teeb liab kev ncaj ncees, kev tswj hwm impedance, thiab txo qis EMI, uas ua rau cov khoom siv hluav taws xob zoo thiab muaj zog.Shenzhen Capel Technology Co., Ltd.manufactures nruj flex pcb thiab saj zawg zog pcb txij thaum 2009 thiab muaj 15 xyoo project kev nyob rau hauv pcb kev lag luam.
