Flex PCB los ua ke sib txawv ntawm Rigid PCB los ua ke hauv cov txheej txheem tsim khoom

PCB (Printed Circuit Board) los ua ke yog ib qho tseem ceeb ntawm kev tsim khoom siv hluav taws xob. Nws koom nrog cov txheej txheem mounting thiab soldering cov khoom siv hluav taws xob mus rau PCB. Muaj ob lub ntsiab ntawm PCB cov rooj sib tham, hloov pauv PCB cov rooj sib tham thiab cov rooj sib txoos PCB nruj. Thaum ob qho tib si ua haujlwm tib lub hom phiaj ntawm kev sib txuas cov khoom siv hluav taws xob, lawv tau tsim txawv.Nyob rau hauv no blog, peb yuav tham txog yuav ua li cas flex PCB los ua ke txawv ntawm nruj PCB los ua ke nyob rau hauv cov txheej txheem tsim.

1. FPC sib dhos:

Ib tug Flex PCB, tseem hu ua ib tug saj zawg zog PCB, yog ib tug Circuit Court board uas yuav tsum tau khoov, folded los yog twisted kom haum ntau yam duab thiab configurations.Nws muaj ntau yam zoo dua li PCBs nruj, xws li txo qhov chaw noj thiab txhim khu kev ruaj ntseg. Kev tsim cov txheej txheem ntawm flex PCB sib dhos suav nrog cov kauj ruam hauv qab no:

a. Flexible PCB Design: Thawj kauj ruam hauv kev sib dhos yooj yim PCB yog los tsim cov txheej txheem hloov pauv hloov pauv.Qhov no suav nrog kev txiav txim siab qhov loj me, cov duab thiab kev teeb tsa ntawm flex PCB. Kev txiav txim siab tshwj xeeb tau muab rau kev teeb tsa ntawm cov kab tooj liab, vias thiab cov ntaub qhwv kom ntseeg tau yooj yim thiab kev ntseeg tau.

b. Kev xaiv cov khoom siv: Cov PCBs yooj yim yog ua los ntawm cov ntaub ntawv hloov pauv xws li polyimide (PI) lossis polyester (PET).Kev xaiv cov khoom yog nyob ntawm qhov yuav tsum tau ua ntawm daim ntawv thov, nrog rau qhov kub thiab txias, hloov tau yooj yim, thiab cov khoom siv kho tshuab.

c. Kev tsim hluav taws xob: Kev tsim PCB yooj yim suav nrog cov txheej txheem xws li photolithography, etching, thiab electroplating.Photolithography yog siv los hloov cov qauv hauv Circuit Court mus rau qhov hloov pauv tau yooj yim. Etching tshem tawm cov tooj liab uas tsis tsim nyog, tawm hauv qhov xav tau circuitry. Plating yog ua los txhim kho conductivity thiab tiv thaiv circuits.

d. Kev tso kawm ntawm cov khoom siv: Hauv kev sib dhos flex PCB, cov khoom siv tau muab tso rau ntawm qhov hloov pauv tau yooj yim siv cov cuab yeej siv saum npoo av (SMT) lossis los ntawm lub qhov.SMT suav nrog kev txuas cov khoom siv hluav taws xob ncaj qha mus rau qhov chaw ntawm lub PCB hloov tau, thaum lub tshuab hluav taws xob los ntawm qhov cuam tshuam nrog kev nkag mus rau hauv qhov ua ntej drilled.

e. Soldering: Soldering yog txheej txheem ntawm kev sib txuas cov khoom siv hluav taws xob rau lub PCB hloov tau.Nws feem ntau yog ua los ntawm reflow soldering los yog yoj soldering cov tswv yim, nyob ntawm seb hom kev tivthaiv thiab kev sib dhos yuav tsum tau ua.

2. Rigid PCB sib dhos:

Rigid PCBs, raws li lub npe qhia, yog cov tsis-flex Circuit Court boards uas tsis tuaj yeem khoov lossis twisted.Lawv feem ntau siv rau hauv cov ntawv thov uas qhov kev ruaj ntseg yog qhov tseem ceeb. Cov txheej txheem tsim khoom rau kev sib dhos PCB sib txawv ntawm flex PCB sib dhos hauv ntau txoj hauv kev:

a. Rigid PCB Design: Rigid PCB designs feem ntau tsom rau kev ua kom muaj qhov sib xyaw ua ke kom zoo thiab ua kom pom kev ncaj ncees.Qhov loj, tus naj npawb ntawm cov khaubncaws sab nraud povtseg, thiab kev teeb tsa ntawm PCB raug txiav txim siab raws li daim ntawv thov.

b. Kev xaiv cov khoom siv: Rigid PCBs yog tsim los ntawm cov khoom siv tawv tawv xws li fiberglass (FR4) lossis epoxy.Cov ntaub ntawv no muaj lub zog zoo heev thiab thermal stability thiab haum rau ntau yam kev siv.

c. Circuit Court fabrication: Rigid PCB fabrication feem ntau muaj cov kauj ruam zoo ib yam li flex PCBs, suav nrog photolithography, etching, thiab plating.Txawm li cas los xij, cov ntaub ntawv siv thiab cov txheej txheem fabrication yuav sib txawv kom haum rau lub rigidity ntawm lub rooj tsavxwm.

d. Kev tso kawm ntawm cov khoom siv: Cov khoom siv tau muab tso rau ntawm PCB nruj siv SMT lossis los ntawm lub qhov tshuab, zoo ib yam li flex PCB sib dhos.Rigid PCBs, txawm li cas los xij, tso cai rau ntau qhov kev teeb tsa ntawm cov khoom vim lawv cov khoom siv.

e. Soldering: Cov txheej txheem soldering rau nruj PCB los ua ke yog zoo ib yam li ntawd rau flex PCB los ua ke.Txawm li cas los xij, cov txheej txheem tshwj xeeb thiab qhov kub thiab txias siv yuav txawv nyob ntawm cov khoom siv thiab cov khoom siv soldered.

Hauv kev xaus:

Plexible PCB sib dhos thiab nruj PCB sib dhos muaj cov txheej txheem tsim khoom sib txawv vim muaj cov yam ntxwv sib txawv ntawm cov ntaub ntawv thiab lawv cov ntawv thov.Flexible PCBs muab kev yooj yim thiab ua haujlwm ntev, thaum cov PCBs nruj muab cov qauv kev ruaj ntseg. Paub qhov txawv ntawm ob hom PCB cov rooj sib tham no yog qhov tseem ceeb hauv kev xaiv qhov kev xaiv tsim nyog rau ib qho kev thov hluav taws xob. Los ntawm kev txiav txim siab txog yam xws li daim foos, cov kev xav tau ntawm txhua yam thiab hloov tau yooj yim, cov tuam ntxhab tuaj yeem ua kom muaj kev ua tau zoo thiab kev ntseeg siab ntawm PCB cov rooj sib txoos.
