Tsim cov cai thiab ceev faj ntawm Rigid Flex PCB

Tus tsim ntawm flex flex PCB yog qhov nyuaj dua li cov qauv PCB ib txwm muaj, thiab muaj ntau qhov chaw uas yuav tsum tau them sai sai rau.Hauv tshwj xeeb, qhov chaw hloov pauv hloov pauv tsis tu ncua, nrog rau kev cuam tshuam ntawm kev sib txuas, kev tsim los ntawm lub qhov, txhua tus yuav tsum ua raws li cov cai ntawm cov qauv tsim.

1. Los ntawm qhov chaw

Nyob rau hauv cov ntaub ntawv ntawm kev siv dynamic, tshwj xeeb tshaj yog thaum lub phaj mos feem ntau khoov, los ntawm qhov ntawm lub phaj mos yuav tsum tau zam kom deb li deb tau, uas yooj yim rau kev puas tsuaj thiab tawg.Txawm li cas los xij, qhov tuaj yeem raug drilled nyob rau hauv qhov chaw txhawb nqa ntawm lub rooj tsavxwm mos, tab sis cov kab ntug ntawm qhov chaw txhawb nqa yuav tsum tau zam.Yog li ntawd, nyob rau hauv tus tsim ntawm rigid flex PCB, thaum drilling, nws yog tsim nyog kom tsis txhob muaj ib tug tej yam kev ncua deb ntawm qhov chaw ua ke.

2. Tsim cov ntaub qhwv thiab ntawm

Thaum lub ncoo thiab ntawm kev ua tau raws li qhov yuav tsum tau muaj hluav taws xob, tus nqi siab tshaj plaws yuav tau txais.Kev sib txuas ntawm lub ncoo thiab tus neeg xyuas pib siv txoj kab hloov pauv kom tsis txhob muaj lub kaum sab xis.Lub ncoo ywj siab yuav tsum tau ntxiv nrog ntiv taw kom ntxiv dag zog rau kev txhawb nqa.

3. Kev tsim hluav taws xob

Hauv cheeb tsam flex, yog tias muaj cov kab ntawm cov txheej txheem sib txawv, sim kom tsis txhob muaj ib kab ntawm cov txheej txheem saum toj kawg nkaus thiab lwm txoj kab ntawm cov txheej hauv qab.Nyob rau hauv txoj kev no, thaum lub rooj tsavxwm hloov tau khoov, qhov kev ntxhov siab ntawm cov txheej sab saud thiab qis ntawm daim ntawv tooj liab tsis zoo ib yam, uas yooj yim ua rau kev puas tsuaj rau cov kab.Es tsis txhob, nws yuav tsum tau staggered thiab txoj kev yuav tsum tau hla.

4. Copper nteg tsim

Rau qhov hloov pauv tau yooj yim ntawm cov phaj hloov tau yooj yim, cov qauv zoo tshaj plaws yog cov qauv mesh.Tab sis rau lub impedance tswj los yog lwm yam kev siv, hluav taws xob zoo ntawm lub network qauv tsis txaus siab.Yog li ntawd, tus tsim qauv yuav tsum tau txiav txim siab tsim nyog seb puas yuav siv cov ntawv xov tooj ntawm tes lossis tooj liab khoom raws li cov qauv tsim.

5. Qhov nrug ntawm qhov drilling qhov thiab daim ntawv tooj liab

Qhov kev ncua deb no hais txog qhov kev ncua deb ntawm ib lub qhov thiab daim ntawv tooj liab.Peb hu nws "qhov tooj liab nrug".Cov khoom siv ntawm flex PCB yog qhov sib txawv ntawm qhov nruj PCB, yog li nws nyuaj rau kev cuam tshuam nrog qhov nruj heev ntawm qhov tooj liab.Feem ntau hais lus, tus qauv qhov tooj liab nrug yuav tsum yog 10mil.

6. Tsim kom muaj kev sib haum xeeb ntawm kev sib xyaw ua ke

Nyob rau hauv qhov sib koom ua ke tsis yooj yim, flex PCB yog qhov zoo tshaj plaws tsim los txuas nrog cov PCB nruj hauv nruab nrab ntawm pawg.Lub flex PCB los ntawm lub qhov nyob rau hauv qhov sib koom ua ke sib koom ua ke yog suav tias yog qhov faus.
