Rogers PCB vs FR4 PCB: Kwatankwacin Kayayyaki da Haɗin Material

Sanin bambance-bambance tsakanin nau'ikan daban-daban yana da mahimmanci lokacin zabar dama na kewaye da aka buga (PCB) don na'urar lantarki. Shahararrun zaɓuɓɓuka biyu akan kasuwa a yau sune Rogers PCB da FR4 PCB. Duk da yake duka biyun suna da ayyuka iri ɗaya, suna da kaddarori daban-daban da abubuwan haɗin kayan aiki, waɗanda zasu iya tasiri sosai akan aikin su. A nan za mu yi wani a-zurfin kwatanta na Rogers PCBs da FR4 PCBs don taimaka maka yin wani bayani yanke shawara don na gaba aikin.

1. Abun abun ciki:

Hukumar Rogers PCBs ta ƙunshi babban mitar yumbu mai cike da laminates tare da kyawawan kaddarorin lantarki kamar ƙarancin ƙarancin wutar lantarki da haɓakar yanayin zafi. A gefe guda, kwamitin FR4 PCB, wanda kuma aka sani da Flame Retardant 4, an yi shi da fiber gilashin ƙarfafa kayan resin epoxy. FR4 sananne ne don ingantaccen rufin lantarki da kwanciyar hankali na inji.

2. Dielectric m da dissipation factor:

Ɗaya daga cikin manyan bambance-bambance tsakanin hukumar da'ira ta Rogers da FR4 kewayen hukumar ita ce dielectric akai-akai (DK) da kuma dissipation factor (DF). Rogers PCBs suna da ƙananan DK da DF suna sa su dace da aikace-aikacen mitoci masu yawa inda amincin sigina yana da mahimmanci. A gefe guda kuma, FR4 da aka buga da'ira suna da babban DK da DF, waɗanda ƙila ba su dace da manyan da'irori masu girma waɗanda ke buƙatar takamaiman lokaci da watsawa ba.

3. Babban aikin mitoci:

An ƙera allunan da'irar da'irar Rogers musamman don ɗaukar sigina masu girma da kuma kiyaye amincin su. Karancin asarar wutar lantarki yana rage asarar sigina da murdiya, yana mai da shi kyakkyawan zaɓi don aikace-aikacen microwave da RF. Wuraren FR4 PCB, yayin da ba a inganta su don manyan mitoci kamar hukumar da'ira ta Rogers PCBs, har yanzu sun dace da maƙasudi na gaba ɗaya da aikace-aikacen tsaka-tsaki.

4. Thermal management:

Game da thermal management, Rogers PCB ya fi FR4 buga kewaye. Matsayinsa mai girma na thermal yana ba da damar haɓakar zafi mai kyau, yana sa ya dace da aikace-aikacen wutar lantarki ko na'urorin da ke haifar da zafi mai yawa. FR4 PCBs suna da ƙananan ƙarancin zafin jiki, wanda zai iya haifar da yanayin zafi mai girma kuma yana buƙatar ƙarin hanyoyin sanyaya.

5. La'akarin farashi:

Farashin wani muhimmin al'amari ne da za a yi la'akari da shi lokacin zabar tsakanin da'irori da aka buga na Rogers da FR4 PCBs. Rogers PCBs gabaɗaya sun fi tsada saboda ƙayyadaddun kayansu na musamman da haɓaka aikinsu. FR4 PCBs ana samarwa da yawa kuma ana samunsu, yana mai da su zaɓi mafi tsada don aikace-aikacen manufa gabaɗaya.

6. Mechanical ƙarfi da karko:

Duk da yake duka Rogers PCB da FR4 PCB suna da ƙarfin injina mai kyau da dorewa, Rogers PCB yana da kwanciyar hankali mafi girma saboda yumbu cike da laminate. Wannan yana sa ya zama ƙasa da yuwuwar gurɓatawa ko lanƙwasa ƙarƙashin matsi. FR4 PCBs sun kasance tabbataccen zaɓi don yawancin aikace-aikace, kodayake ana iya buƙatar ƙarin ƙarfafawa don ƙarin mahalli masu tsauri.
Dangane da binciken da ke sama, ana iya ƙaddamar da cewa zaɓi tsakanin PCBs Rogers da FR4 PCBs ya dogara da takamaiman buƙatun aikin ku. Idan kuna aiki a cikin aikace-aikacen mitoci masu yawa waɗanda ke buƙatar ingantaccen siginar siginar da sarrafa yanayin zafi, Rogers PCBs na iya zama mafi kyawun zaɓi, kodayake a farashi mafi girma. A gefe guda, idan kuna neman mafita mai inganci don maƙasudi na gaba ɗaya ko aikace-aikacen tsaka-tsaki, FR4 PCBs na iya biyan bukatun ku yayin samar da ƙarfin injina mai kyau. Daga ƙarshe, fahimtar kaddarorin da abubuwan abun ciki na waɗannan nau'ikan PCB zai taimaka muku yanke shawara mai zurfi waɗanda suka dace da bukatun aikinku.
