There are two main types of circuits and circuit boards used in industry and mass manufacturing: yooj ywm PCB thiab yooj ywm PCB. Ob hom no txawv ntawm ib txwm ua nruj ua tsiv PCBS. Raws li koj xav tau, cov pawg thawj coj no tau tsim nrog kev sib xyaw ua ke ntawm cov khoom siv tau yooj yim thiab txhav thiab thev naus laus zis. Lub rooj tsav xwm hloov pauv tau hloov pauv nrog tooj liab thiab cov khoom sib xws. Lub hom phiaj tseem ceeb yog txhawm rau muab kev ywj pheej txaus thiab ua kom muaj zog tiv taus. Saj zawg zog txhav PCBS, ntawm qhov tod tes, tau tsim los siv kev sib txuas ntawm ob lub thev naus laus zis thiab muaj thaj tsam hloov pauv tau thiab nruj.

Saj zawg zog luam tawm Circuit Board

Cov kab hluav taws xob luam tawm tau yooj yim tau txiav txim siab “hloov pauv” rau ntau qhov laj thawj, tab sis qhov pom tseeb tshaj plaws yog tias lawv cov khoom siv hluav taws xob tuaj yeem tsim los kom haum cov khoom siv hluav taws xob lossis cov khoom tseem ceeb. Manufacturers are not forced to create products or housings around circuit boards. Hloov chaw, lawv tuaj yeem hloov kho cov laug cam kom haum rau cov qauv uas twb muaj lawm. Qhov no muaj txiaj ntsig thaum tsim cov khoom lossis khoom siv nrog tsim qauv raug cai. Piv txwv li, yog tias koj txhawj xeeb txog qhov hnyav tag nrho, nqa tau yooj yim, thiab siv tau ntev ntawm ib lub cuab yeej tshwj xeeb, ib lub rooj tsav xwm hauv ib cheeb tsam yuav ua tsis tau.

Qhov zoo thiab qhov tsis zoo ntawm Flex-rigid PCB

Qee zaum, cov laug cam hloov pauv yuav tsum hloov kho rau cov khoom txwv. Piv txwv li, pawg thawj coj loj yuav tsum tau txo qis, thiab yuav tsum tau hloov chaw lossis rov tsim kho kom haum rau cov tsev tshwj xeeb thiab qhov ntev. All circuits are laid out in different patterns – including components – which are then highlighted by a malleable base material such as copper. Cov rooj sib tham luam tawm cov kab hluav taws xob kuj tau ua rau txoj hauv kev no, tshwj tsis yog cov khoom siv tau hnyav dua thiab muaj zog dua.

Qhov zoo thiab qhov tsis zoo ntawm PCB yooj ywm:

• Kev ntseeg tau: tus nqi zoo vim yog tshem tawm cov khoom siv sib txuas;

• Cost: higher cost than rigid or flexible rigidity;

• Temperature resistance: general;

• Yooj yim hloov pauv thiab hloov pauv tau;

• Muaj peev xwm hloov kho rau txhua qhov kev tsim;

• Tsim nyog rau kev txav nrawm thiab muaj kev nyuaj siab;

Flex-rigid luam tawm cov laug cam

Flex- Rigid PCBS tau txais lawv lub npe los ntawm kev sib koom ua ke ntawm cov chaw hloov pauv tau yooj yim thiab nruj uas lawv siv. Like most printed circuit boards, flexible rigid boards have multiple layers, but usually more than traditional designs.

Cov txheej txheem txheej txheem ntxiv no ua haujlwm nruj lossis hloov pauv tau txheej txheej, nyob ntawm cov khoom xav tau. Cov txheej txheej sab nrauv ntawm lub rooj tsav xwm hauv Circuit Court – tsis muaj teeb meem pes tsawg tus muaj – feem ntau muaj lub ncoo liab qab lossis phaj npog rau kev nyab xeeb. Cov lus qhia tau siv rau txheej txheej txheej nruj, thaum hloov pauv tau los ntawm lub qhov yog siv rau ib qho hloov pauv tau thiab nruj txheej ntxiv.

Some projects require the use of traditional rigid techniques and designs. Others have restrictions that prevent manufacturers from using these larger, less flexible boards. Piv txwv li, cov khoom siv txawb thiab nqa tau yuav raug cuam tshuam yog tias tus qauv tsim qauv siv. Muaj ntau qhov txav chaw thiab cov khoom siv uas ua tsis tau zoo nyob rau qee qhov xwm txheej. Cov khoom siv hauv xov tooj yuav tsum nqa tau, lub teeb thiab tuaj yeem tiv taus cov xwm txheej xws li cua sov, txias thiab qee zaum cov av noo.

Advantages and disadvantages of Flex Rigid PCB:

• Kev ntseeg tau: zoo heev vim tias nws txo qhov xav tau cov laug txuas;

• Tus Nqi: qis dua li lub rooj tsav xwm hloov pauv tau yooj yim;

• Temperature resistance: excellent;

• Haum rau qhov nruab nrab mus rau me ntsis siab dua qhov kev tawm suab thiab kev ntxhov siab;

• Yooj yim dua thiab yoog raws li cov rooj sib tham ib txwm muaj;

• Kev ntseeg tau mus sij hawm ntev vim tsis muaj kev sib txuas thiab cov khoom siv tsawg; • Yuav tsum tau saib xyuas tsawg kawg nkaus;

Saj zawg zog thiab yoog raws – PCB tus yam ntxwv tshwj xeeb ua rau nws zoo rau kev siv sib txawv. Thaum xaiv ntawm cov yoog raws, yoog raws cov phaj nruj thiab cov phaj nruj, xav txog cov yam ntxwv uas xav tau rau kev tsim qauv.
