Capel Kukumana ndi Siginecha Yakuthamanga Kwambiri ndi Zofunikira Zopanga za EMC pa Ma Circuits Complex PCB

Tsegulani:

M'dziko lomwe likukula mwachangu la kamangidwe ka makina osindikizira (PCB), kukwaniritsa zofunikira za ma siginecha othamanga kwambiri komanso zofananira ndi ma electromagnetic (EMC) ndizovuta kwambiri. Pamene luso lamakono likupita patsogolo ndi zipangizo zamagetsi zimakhala zovuta kwambiri, pakufunikanso mabwalo ovuta a PCB omwe amatha kunyamula ma siginecha othamanga kwambiri ndikusunga ma elekitiromaginetiki.Mubulogu iyi, tiwunika zomwe Capel wabwera kumene pamsika ndikukambirana ngati angakwanitse kukwaniritsa ma signature othamanga kwambiri komanso kapangidwe ka EMC ka mabwalo ovuta a PCB.

Phunzirani za kapangidwe ka ma signal othamanga kwambiri:

Mapangidwe azizindikiro zothamanga kwambiri amagwira ntchito yofunika kwambiri pozindikira momwe zida zamagetsi zimagwirira ntchito. Mizere yotumizira ma frequency okwera kwambiri komanso ma siginecha osinthira mwachangu amafunikira kukhulupirika kwazizindikiro kuti apewe zovuta zosiyanasiyana za kukhulupirika kwazizindikiro monga crosstalk, zowunikira, ndi kupotoza kwa ma sign. Kukwaniritsa magwiridwe antchito azizindikiro zothamanga kwambiri kumafunikira kuganiziridwa mozama monga kuwongolera kwa impedance, kuwongolera kowongolera ndi kusanthula kukhulupirika kwa ma sign.

Mapangidwe a Electromagnetic Compatibility (EMC):

EMC idapangidwa kuti iwonetsetse kuti zida zamagetsi zimagwira ntchito limodzi pamalo opangira ma elekitiroma popanda kusokoneza kapena kusokoneza. Kupanga koyenera kwa EMC kumaphatikizapo kuchepetsa ma radiation a electromagnetic opangidwa ndi PCB ndikuwonjezera chitetezo chamderalo ku kusokoneza kwamagetsi akunja (EMI). Nkhani za EMC zitha kuthetsedwa bwino potsatira njira zochepetsera phokoso monga kuyika pansi koyenera, kuwongolera ma sigino, kutchingira, ndi kulumikiza.

Za Capel:

Capel ndi pulogalamu yatsopano yopangira PCB yomwe imati imapangitsa kuti ma signature azithamanga kwambiri komanso EMC. Imakhala ndi zida zapamwamba komanso magwiridwe antchito opangidwira kuthana ndi zovuta zomwe zimagwirizanitsidwa ndi mabwalo ovuta a PCB. Tiyeni tiwone mwatsatanetsatane mbali zake zazikulu:

1. Kusanthula kwamphamvu kwambiri:

Capel imapereka zida zamakono zowunikira ma siginecha othamanga kwambiri omwe amathandiza opanga kuneneratu molondola ndikusanthula nkhani za kukhulupirika kwa chizindikiro. Ndi chowerengera chake cha impedance, opanga amatha kuwonetsetsa kufananiza kwa impedance, kuchepetsa zowunikira komanso kusunga kukhulupirika kwa ma sign. Kuphatikiza apo, Capel imapereka luso lapamwamba loyerekeza kuti lizindikire ndikuchepetsa kufalikira, kuwonetsetsa kuti kutumizirana ma siginecha odalirika kwambiri.

2. Kusanthula ndi kukhathamiritsa kwa EMC:

Capel akugogomezera kufunikira kwa kusanthula kwa EMC kuyambira magawo oyambilira a mapangidwe a PCB. Imapereka ma module oyerekeza kuti athandizire kuzindikira komwe kungayambitse kusokoneza kwa ma electromagnetic (EMI) ndikuwunika momwe amayendera mabwalo. Pogwiritsa ntchito njira zapamwamba zowunikira za EMC, opanga amatha kuzindikira ndikuthana ndi zovuta zomwe zingagwirizane ndi ma electromagnetic kuti awonetsetse kuti akutsatira miyezo yamakampani.

3. Kuwona Malamulo Kapangidwe (DRC) ndi Kutsimikizira Mapangidwe:

Capel ili ndi macheke ambiri a malamulo apangidwe omwe amathandiza opanga kutsimikizira mapangidwe awo a PCB motsutsana ndi ma siginecha othamanga kwambiri komanso zofunikira zamapangidwe a EMC. DRC imawonetsetsa kuti malamulo ofunikira amapangidwe akukwaniritsidwa, kuletsa zolakwika zomwe zingachitike ndikuwonetsetsa kuti magwiridwe antchito ali bwino.

4. Mgwirizano ndi kuphatikiza:

Capel imalola mgwirizano wosasunthika pakati pa mamembala a gulu, kuthandizira kuyankhulana kwa nthawi yeniyeni ndi kayendetsedwe ka polojekiti. Kuphatikiza apo, imapereka kuphatikizika ndi zida zofananira zamapangidwe ndi mapulogalamu, zomwe zimalola opanga kuti azigwira ntchito mkati mwamayendedwe awo omwe amakonda pomwe akugwiritsa ntchito mphamvu ya Capel.

Pomaliza:

Pamene zida zamagetsi zikupitilirabe kusinthika, kufunikira kwa ma PCB odalirika omwe amatha kukumana ndi ma signature othamanga kwambiri komanso zofunikira za kapangidwe ka EMC kwakhala kofunikira. Ngakhale kuti Capel, wongobwera kumene pamsika, akulonjeza kuti athetse mavutowa pogwiritsa ntchito zida zake zapamwamba ndi ntchito zake, okonza mapulani ayenera kufufuza bwino mphamvu zake ndikufufuza momwe akukwaniritsira zofunikira zawo zapangidwe. Pochita bwino pakati pa mapangidwe amtundu wothamanga kwambiri ndi malingaliro a EMC, opanga amatha kuonetsetsa kuti mabwalo a PCB amphamvu komanso ogwira ntchito omwe amakhazikitsa zatsopano pazida zamagetsi zamtsogolo.
