Rogers Pcb yog dab tsi?

Rogers PCB, tseem hu ua Rogers Printed Circuit Board, yog dav nrov thiab siv nyob rau hauv ntau yam lag luam vim nws superior kev ua tau zoo thiab kev ntseeg tau. Cov PCBs no yog tsim los ntawm cov khoom siv tshwj xeeb hu ua Rogers laminate, uas muaj cov khoom siv hluav taws xob tshwj xeeb thiab cov khoom siv kho tshuab. Nyob rau hauv no blog ncej, peb yuav dhia mus rau hauv intricacies ntawm Rogers PCB raug, tshawb txog cov txheej txheem, cov ntaub ntawv, thiab cov kev xav tau koom nrog.

Txhawm rau nkag siab txog Rogers PCB cov txheej txheem tsim khoom, peb yuav tsum xub nkag siab tias cov laug cam no yog dab tsi thiab nkag siab tias Rogers laminates txhais li cas.PCBs yog cov khoom tseem ceeb ntawm cov khoom siv hluav taws xob, muab cov qauv kev txhawb nqa thiab kev sib txuas hluav taws xob. Rogers PCBs tau nrhiav tau zoo heev hauv cov ntawv thov uas xav tau cov teeb liab sib kis tau zoo, tsis tshua muaj kev poob thiab ruaj khov. Lawv tau siv dav hauv kev lag luam xws li kev sib txuas lus, aerospace, kho mob thiab tsheb.

Rogers Corporation, tus kws tshaj lij cov ntaub ntawv daws teeb meem, tsim Rogers laminates tshwj xeeb rau kev siv hauv kev tsim cov khoom siv hluav taws xob zoo. Rogers laminate yog cov khoom siv sib xyaw uas muaj cov ntaub qhwv cov ntaub qhwv fiberglass nrog hydrocarbon thermoset resin system. Qhov sib tov no nthuav tawm cov khoom hluav taws xob zoo heev xws li tsis muaj dielectric poob, siab thermal conductivity thiab zoo heev qhov ntev.

Tam sim no, cia peb delve rau hauv Rogers PCB kev tsim khoom:

1. Tsim layout:

Thawj kauj ruam hauv kev ua ib qho PCB, suav nrog Rogers PCBs, suav nrog kev tsim cov qauv hauv Circuit Court. Cov engineers siv software tshwj xeeb los tsim schematics ntawm Circuit Court boards, tso thiab txuas cov khoom kom tsim nyog. Qhov pib tsim theem no yog qhov tseem ceeb hauv kev txiav txim siab ua haujlwm, kev ua tau zoo, thiab kev ntseeg siab ntawm cov khoom kawg.

2. Kev xaiv cov khoom siv:

Thaum qhov kev tsim ua tiav, kev xaiv cov khoom siv tseem ceeb heev. Rogers PCB yuav tsum xaiv cov khoom siv laminate uas tsim nyog, suav nrog cov khoom siv xws li qhov yuav tsum tau muaj dielectric tas li, dissipation factor, thermal conductivity, thiab mechanical zog. Rogers laminates muaj nyob rau hauv ntau qib kom tau raws li qhov kev thov sib txawv.

3. Txiav lub laminate:

Nrog rau kev tsim thiab xaiv cov khoom tiav, cov kauj ruam tom ntej yog txiav Rogers laminate kom loj. Qhov no tuaj yeem ua tiav los ntawm kev siv cov cuab yeej tshwj xeeb xws li CNC tshuab, xyuas kom meej qhov ntev thiab tsis txhob muaj kev puas tsuaj rau cov khoom.

4. Drilling thiab tooj liab pouring:

Nyob rau theem no, lub qhov yog drilled rau hauv lub laminate raws li lub Circuit Court tsim. Cov qhov no, hu ua vias, muab kev sib txuas hluav taws xob ntawm cov txheej txheem sib txawv ntawm PCB. Cov qhov drilled yog ces tooj liab plated los tsim conductivity thiab txhim kho cov qauv kev ncaj ncees ntawm cov vias.

5. Circuit Court duab:

Tom qab drilling, ib txheej ntawm tooj liab yog siv rau lub laminate los tsim cov kab hluav taws xob xav tau rau PCB txoj haujlwm. Copper-clad board yog coated nrog lub teeb-sensitive khoom hu ua photoresist. Cov qauv tsim hluav taws xob tau raug xa mus rau photoresist siv cov txheej txheem tshwj xeeb xws li photolithography lossis duab ncaj qha.

6. Kev sib tw:

Tom qab cov qauv tsim hluav taws xob tau luam tawm ntawm lub photoresist, cov tshuaj etchant yog siv los tshem tawm cov tooj liab ntau dhau. Lub etchant dissolves lub pliaj tooj liab, tawm hauv qab cov yam xav tau Circuit Court. Cov txheej txheem no tseem ceeb heev rau kev tsim cov kab hluav taws xob uas xav tau rau PCB cov hluav taws xob sib txuas.

7. Txheej txheej thiab lamination:

Rau ntau txheej Rogers PCBs, cov khaubncaws sab nraud povtseg ntawm tus kheej tau ua raws nraim nrog cov khoom siv tshwj xeeb. Cov txheej no yog stacked thiab laminated ua ke los tsim cov qauv cohesive. Thaum tshav kub kub thiab siab yog siv rau lub cev thiab hluav taws xob sib txuas cov khaubncaws sab nraud povtseg, kom ntseeg tau conductivity ntawm lawv.

8. Electroplating thiab nto kho:

Txhawm rau tiv thaiv cov khoom siv hluav taws xob thiab ua kom muaj kev ntseeg tau ntev, PCB tau dhau los ua txheej txheem plating thiab kho qhov chaw. Ib txheej nyias ntawm cov hlau (feem ntau yog kub lossis tin) yog plated rau ntawm qhov chaw tooj liab. Cov txheej no tiv thaiv corrosion thiab muab qhov chaw zoo rau cov khoom siv soldering.

9. Solder daim npog qhov ncauj thiab silk screen daim ntawv thov:

Lub PCB nto yog coated nrog ib lub npog ntsej muag (feem ntau yog ntsuab), tawm tsuas yog thaj chaw uas yuav tsum tau muaj rau kev sib txuas. Cov txheej txheem tiv thaiv no tiv thaiv cov kab tooj liab los ntawm ib puag ncig yam xws li ya raws, plua plav, thiab kev sib cuag tsis zoo. Tsis tas li ntawd, cov khaubncaws sab nraud povtseg tuaj yeem muab ntxiv rau cov cim kev teeb tsa, cov neeg tsim qauv siv thiab lwm yam ntaub ntawv cuam tshuam ntawm PCB nto.

10. Kev Ntsuas thiab Kev Tswj Xyuas Zoo:

Thaum cov txheej txheem tsim khoom tiav lawm, kev kuaj xyuas thiab kev soj ntsuam zoo yog ua los xyuas kom meej tias PCB ua haujlwm tau zoo thiab ua tau raws li cov qauv tsim. Ntau yam kev ntsuam xyuas xws li kev soj ntsuam txuas ntxiv, kev ntsuas hluav taws xob siab thiab kev ntsuas impedance txheeb xyuas qhov kev ncaj ncees thiab kev ua haujlwm ntawm Rogers PCBs.

Hauv cov ntsiab lus

Kev tsim ntawm Rogers PCBs suav nrog cov txheej txheem zoo uas suav nrog kev tsim thiab kev teeb tsa, xaiv cov khoom siv, txiav laminates, drilling thiab tooj liab pouring, circuit imaging, etching, txheej txheej thiab lamination, plating, npaj nto, solder daim npog qhov ncauj thiab tshuaj ntsuam luam ntawv daim ntaub ntawv nrog rau tag nrho. kuaj thiab tswj kom zoo. Kev nkag siab txog qhov tsis sib xws ntawm Rogers PCB kev tsim khoom qhia txog kev saib xyuas, kev ua tau zoo, thiab kev txawj ntse koom nrog hauv kev tsim cov boards ua tau zoo.
