Mipikisano wosanjikiza flexible PCB Impedans ulamuliro luso ndi kuyesa njira

Capel: Mnzanu wodalirika wopanga ma PCB osiyanasiyana

Kuyambira 2009, Capel wakhala ali patsogolo pa mafakitale opanga zamagetsi, akuyang'ana kwambiri kupanga ndi kupanga mapepala apakati-mpaka-okwera-otsika kwambiri, matabwa ozungulira ozungulira, ndi HDI PCBs, ndipo wakhala wodalirika wopanga zamagetsi. . Ndi bwenzi lodalirika lamakampani ambiri m'mafakitale osiyanasiyana. Ndi zaka 15 zamakampani olemera komanso luso laukadaulo, gulu lamphamvu la akatswiri, komanso zida zapamwamba zopangira makina, Capel yadzipereka kupatsa makasitomala njira zodalirika komanso zofulumira zopanga ma projekiti kuti ayambitse ntchito zawo.

Kwa ma PCB osinthika amitundu yambiri, ukadaulo wowongolera ma impedance ndi njira zoyesera zimagwira ntchito yofunika kwambiri pakuwonetsetsa kulondola komanso kulondola kwazomwe amapanga.Mu positi iyi yabulogu, tiwona momwe mungasankhire ukadaulo wowongolera wolepheretsa komanso njira yoyesera ya PCB yanu yosinthika yamitundumitundu, komanso chifukwa chake Capel ndiye chisankho choyenera pazosowa zanu zopanga.

Phunzirani zaukadaulo wa impedance control

Ukadaulo wowongolera wa Impedans umatanthawuza kasamalidwe ka PCB mkati mwamagetsi. Zimatsimikizira kuti zizindikiro zomwe zimaperekedwa kudzera mu dera la PCB sizikhudzidwa ndi kusokoneza kwakunja, motero zimatsimikizira kuti ntchito yonse ndi yodalirika ya chipangizocho. Kwa ma PCB osinthika amitundu yambiri, kuwongolera kwa impedance kumakhala kofunika kwambiri chifukwa chazovuta za dera.

Gawo loyamba pakusankha ukadaulo wowongolera wa impedance ndikumvetsetsa zofunikira zenizeni zamapangidwe a PCB osinthika ambiri. Zinthu monga ma frequency a siginecha, makulidwe a board, dielectric constant, makulidwe amkuwa, ndi zinthu zapansi panthaka zonse zimakhudza mtengo wa impedance. Ndi molondola kudziwa magawowa, mukhoza kusankha yoyenera impedance ulamuliro luso kwa PCB wanu.

Mitundu ya Impedans Control Technology

1. Njira zopangira:Njira imodzi yowongolerera kuwongolera ndi kupanga mawonekedwe a PCB kuti akwaniritse zomwe mukufuna. Izi zimaphatikizapo kusintha makulidwe a trace, kagawo kakang'ono, ndi kuwerengetsera kuti zigwirizane ndi zofunikira. Capel amagwiritsa ntchito opanga odziwa zambiri omwe ali ndi luso lowongolera kuti awonetsetse kuti masanjidwe anu a PCB osinthika osiyanasiyana akukwaniritsa zomwe mukufuna.

2. Kuwongolera dielectric constant:Kusankha chinthu chokhala ndi dielectric yodziwika komanso yokhazikika ndi njira ina yokwaniritsira kuwongolera kwa impedance. Posankha gawo lapansi lomwe lili ndi zida zenizeni za dielectric, mutha kukhalabe ndi zikhalidwe zosasinthika mu PCB yosinthika yama multilayer. Capel imagwiritsa ntchito zida zapamwamba kwambiri zokhala ndi ma dielectric odalirika kuti zitsimikizire kuwongolera kolondola kwa impedance.

3. Zophatikizidwa:Kuyika zida zongoyang'ana, monga ma resistors ndi ma capacitors, mkati mwa PCB zitha kuthandizira kukwaniritsa kuwongolera. Ukadaulowu umafuna palibe zigawo zakunja, kuchepetsa kukula konse ndi kulemera kwa PCB ndikusunga zikhalidwe zofananira. Kuthekera kwa Capel kuyika bwino zigawozi kumapititsa patsogolo magwiridwe antchito ndi kudalirika kwa ma PCB osinthika osiyanasiyana.

Sankhani njira yoyenera yoyesera

Ukadaulo woyenera wowongolera wa impedance ukasankhidwa, kuyezetsa koyenera ndikofunikira kuti muwonetsetse kuti ma PCB osinthika osiyanasiyana amakwaniritsa zofunikira. Capel amagwiritsa ntchito njira zapamwamba zoyesera kuti zitsimikizire kuti PCB ndi yolondola komanso yogwira ntchito.

1. Time Domain Reflectometry (TDR):TDR ndi njira yodziwika bwino yoyezera kuleka kwa impedance. Potumiza kugunda kudzera pamzere wopatsira ndikuwunika mawonekedwe owonetseredwa, kusagwirizana kwa impedance ndi zovuta zina za kukhulupirika kwa chizindikiro zitha kudziwika. Capel amagwiritsa ntchito kuyesa kwa TDR kuyeza molondola kulepheretsa kwa ma PCB osinthika osiyanasiyana.

2. Vector Network Analyzer (VNA):VNA ndi chida chogwiritsa ntchito zambiri chomwe chimagwiritsidwa ntchito kuyeza mawonekedwe amagetsi pazida zothamanga kwambiri, kuphatikizapo impedance. Imapereka miyeso yolondola pama frequency osiyanasiyana, ndikupangitsa kuti ikhale yoyenera kuyesa ma PCB osinthika amitundu yambiri okhala ndi zofunikira zosiyanasiyana za impedance. Capel amagwiritsa ntchito kuyesa kwa VNA kuti atsimikizire kukhulupirika kwa mapangidwe a PCB.

3. Chigamba choyesera:Kugwiritsa ntchito chigamba choyeserera ndi gawo loyimira la PCB yeniyeni ndipo ndi njira yabwino yotsimikizira mtengo wa impedance. Popanga gawo linalake la PCB yokhala ndi mtengo wodziwikiratu wodziwikiratu, opanga amatha kufananiza kulepheretsa koyezedwa ndi mtengo womwe ukuyembekezeka. Capel amagwiritsa ntchito makuponi oyesera kuti atsimikizire kulondola kwa kuwongolera kwa impedance mu ma PCB osinthika ambiri.

Chifukwa chiyani musankhe Capel pazosowa zanu za PCB zamitundu yambiri?

Pokhala ndi chidziwitso chambiri pakupanga ma board osinthika apamwamba kwambiri komanso kudzipereka kugwiritsa ntchito ukadaulo wapamwamba, Capel ndiye chisankho choyenera pazofunikira zanu za PCB zosinthika zingapo. Sankhani Capel, mudzapindula ndi:

1. Makampani olemera komanso luso laukadaulo:
Zaka 15 za ntchito ya Capel ndi umboni wa kudzipereka kwake ku khalidwe labwino ndi luso. Capel ali ndi gulu lamphamvu la akatswiri omwe amamvetsetsa zovuta zapadera zomwe zimagwirizanitsidwa ndi kupanga ma PCB osinthika ambiri ndipo amatha kupereka zidziwitso zofunikira ndi zothetsera.

2. Zida zapamwamba zodziwikiratu zokha:
Kugulitsa kwa Capel pazida zapamwamba zopangira makina kumatsimikizira kulondola komanso kuchita bwino panthawi yonse yopangira. Pogwiritsa ntchito ukadaulo waposachedwa, Capel imapereka ma prototyping odalirika, othamanga kuti mumalize ntchito yanu panthawi yake.

3. Kudzipereka pakupambana kwamakasitomala:
Ku Capel, kukhutira kwamakasitomala ndikofunikira kwambiri. Popereka zopangapanga zodalirika, ukatswiri waukadaulo komanso ntchito yapadera yamakasitomala, Capel yadzipereka kuthandiza makasitomala kukhazikitsa bwino ntchito zawo. Kuyang'ana kwa Capel pakuchita bwino kwamakasitomala kumasiyanitsa ndi opanga ma PCB ena.

Powombetsa mkota,kusankha luso lolondola la impedance control ndi njira zoyesera za ma PCB osinthika ambiri ndikofunikira kuti mupeze zotsatira zolondola komanso zodalirika. Pogwirizana ndi Capel, mutha kupititsa patsogolo luso lake lamakampani, zida zapamwamba zopangira komanso kudzipereka pakupambana kwamakasitomala kuwonetsetsa kuti PCB yanu yosinthika yamitundu yambiri ikukwaniritsa miyezo yapamwamba kwambiri komanso magwiridwe antchito.
