Rogers PCB vs FR4 PCB: Kufananiza kwa Katundu ndi Kupanga Zinthu

Kudziwa kusiyana kwa mitundu yosiyanasiyana ndikofunikira posankha bolodi yoyenera yosindikizidwa (PCB) pa chipangizo chanu chamagetsi. Zosankha ziwiri zodziwika pamsika lero ndi Rogers PCB ndi FR4 PCB. Ngakhale kuti onsewa ali ndi ntchito zofanana, ali ndi katundu wosiyana ndi zolemba zakuthupi, zomwe zingakhudze kwambiri ntchito yawo. Apa tifanizira mozama ma Rogers PCBs ndi ma FR4 PCBs kuti akuthandizeni kupanga chiganizo mwanzeru cha polojekiti yanu yotsatira.

1. Zolemba:

Rogers PCBs board imakhala ndi ma laminates odzazidwa ndi ma ceramic pafupipafupi okhala ndi zinthu zabwino kwambiri zamagetsi monga kuchepa kwa dielectric komanso kutsika kwamafuta. Kumbali inayi, bolodi la FR4 PCB, lomwe limadziwikanso kuti Flame Retardant 4, limapangidwa ndi magalasi opangidwa ndi epoxy resin resin. FR4 imadziwika chifukwa cha kutchinjiriza kwake kwamagetsi komanso kukhazikika kwamakina.

2. Dielectric nthawi zonse ndi dissipation factor:

Kusiyanitsa kwakukulu pakati pa bolodi la Rogers ndi FR4 circuit board ndi dielectric constant (DK) ndi dissipation factor (DF). Ma PCB a Rogers ali ndi DK yotsika ndi DF kuwapangitsa kukhala oyenera kugwiritsa ntchito pafupipafupi pomwe kukhulupirika kwa siginecha ndikofunikira. Kumbali ina, bolodi yosindikizidwa ya FR4 ili ndi DK yayikulu ndi DF, zomwe sizingakhale zabwino pamabwalo othamanga kwambiri omwe amafunikira nthawi yolondola komanso kutumiza.

3. Kuchita pafupipafupi:

Ma board a Rogers osindikizidwa amapangidwa makamaka kuti azigwira ma siginecha apamwamba kwambiri ndikusunga kukhulupirika kwawo. Kutayika kwake kochepa kwa dielectric kumachepetsa kutayika kwa ma sign ndi kupotoza, ndikupangitsa kukhala chisankho chabwino kwambiri pakugwiritsa ntchito ma microwave ndi RF. Mabwalo a FR4 PCB, ngakhale sanakomedwe ndi ma frequency apamwamba ngati ma Rogers PCBs circuit board, akadali oyenera kugwiritsa ntchito zolinga wamba komanso ma frequency apakati.

4. Kasamalidwe ka kutentha:

Pankhani ya kasamalidwe kamafuta, Rogers PCB ndiyabwino kuposa FR4 yosindikizidwa. Kutentha kwake kwapamwamba kumapangitsa kuti kutentha kwabwino kuwonongeke, kumapangitsa kuti zikhale zoyenera kugwiritsa ntchito mphamvu kapena zipangizo zomwe zimapanga kutentha kwakukulu. FR4 PCBs ndi otsika matenthedwe madutsidwe, zomwe zingachititse kuti apamwamba ntchito kutentha ndi amafuna njira zina kuzirala.

5. Kuganizira zamtengo:

Mtengo ndi gawo lofunikira lomwe muyenera kuliganizira posankha pakati pa mabwalo osindikizidwa a Rogers ndi ma FR4 PCB. Ma PCB a Rogers nthawi zambiri amakhala okwera mtengo kwambiri chifukwa cha kapangidwe kake ka zinthu zapadera komanso kupititsa patsogolo magwiridwe antchito.FR4 PCBs amapangidwa mochuluka ndipo amapezeka mosavuta, zomwe zimawapangitsa kukhala otsika mtengo kwambiri pakugwiritsa ntchito zolinga wamba.

6. Mphamvu zamakina ndi kulimba:

Ngakhale onse a Rogers PCB ndi FR4 PCB ali ndi mphamvu zamakina abwino komanso kulimba, Rogers PCB ili ndi kukhazikika kwamakina chifukwa chakudzaza kwake ndi laminate. Izi zimapangitsa kuti zisakhale zopunduka kapena kupindika pokakamizidwa. Ma FR4 PCB amakhalabe chisankho chokhazikika pamapulogalamu ambiri, ngakhale kulimbitsa kwina kungafunike m'malo ovuta kwambiri.
Kutengera kusanthula pamwambapa, tinganene kuti kusankha pakati pa Rogers PCBs ndi FR4 PCBs kumadalira zofunikira za polojekiti yanu. Ngati mukugwira ntchito pafupipafupi kwambiri zomwe zimafuna kukhulupirika kwachizindikiro komanso kasamalidwe kamafuta, ma Rogers PCB atha kukhala chisankho chabwinoko, ngakhale pamtengo wokwera. Kumbali ina, ngati mukuyang'ana njira yotsika mtengo yogwiritsira ntchito zolinga wamba kapena zapakati pafupipafupi, ma FR4 PCB amatha kukwaniritsa zomwe mukufuna kwinaku akukupatsani mphamvu zamakina. Pamapeto pake, kumvetsetsa zamitundu ndi zinthu zamitundu iyi ya PCB kudzakuthandizani kupanga zisankho zomwe zikugwirizana ndi zosowa zanu.
