Rogers PCB vs FR4 PCB: Kuenzaniswa Kwezvivakwa uye Kuumbwa Kwezvinhu

Kuziva mutsauko pakati pemhando dzakasiyana kwakakosha pakusarudza yakakodzera yakadhindwa redunhu bhodhi (PCB) yechigadzirwa chako chemagetsi.Sarudzo mbiri dzakakurumbira pamusika nhasi ndiRogers PCB uye FR4 PCB.Nepo ese ari maviri ane mabasa akafanana, ane akasiyana zvivakwa uye zvinhu zvekuumbwa, izvo zvinogona kukanganisa zvakanyanya kuita kwavo.Pano tichaita kuenzanisa kwakadzama kweRogers PCBs uye FR4 PCBs kuti ikubatsire kuita sarudzo ine ruzivo yepurojekiti yako inotevera.

1. Kuumbwa kwezvinhu:

Rogers PCBs board ine yakakwira frequency ceramic yakazadzwa laminates ane akanakisa emagetsi zvivakwa senge yakaderera dielectric kurasikirwa uye yakanyanya kupisa conductivity.Kune rimwe divi, FR4 PCB bhodhi, inozivikanwawo seFlame Retardant 4, yakagadzirwa negirazi fiber yakasimbiswa epoxy resin zvinhu.FR4 inozivikanwa nekunaka kwayo magetsi ekudzivirira uye kugadzikana kwemagetsi.

2. Dielectric nguva dzose uye disipation factor:

Mumwe wemisiyano mikuru pakati peRogers wedunhu bhodhi uye FR4 wedunhu bhodhi ndiyo yavo dielectric constant (DK) uye dissipation factor (DF).Rogers PCBs ine yakaderera DK uye DF ichiita kuti ive yakakodzera kune yakakwira frequency application uko kutendeseka kwechiratidzo kwakakosha.Kune rimwe divi, FR4 yakadhindwa yedunhu bhodhi ine yakakwira DK uye DF, iyo inogona kunge isiri yakakodzera kune yakakwirira-frequency maseketi anoda chaiyo nguva uye kutapurirana.

3. High frequency performance:

Rogers akadhindwa edunhu mabhodhi akagadzirirwa chaizvo kubata yakakwirira frequency masaini uye kuchengetedza kutendeseka kwavo.Kurasika kwayo kwakaderera dielectric kunoderedza kurasikirwa kwechiratidzo uye kukanganisa, zvichiita kuti ive sarudzo yakanaka kune microwave uye RF application.FR4 PCB maseketi, nepo asina kukwidziridzwa kune yakakwira frequency seRogers PCBs redunhu bhodhi, achiri akakodzera kune general-chinangwa uye yepakati-frequency application.

4. Kutarisira kupisa:

Panyaya yekutonga kwemafuta, Rogers PCB iri nani pane FR4 yakadhindwa sedunhu.Kupisa kwayo kwepamusoro kunogonesa kupisa kwekushisa, zvichiita kuti zvive zvakakodzera kushandiswa kwemagetsi kana zvigadzirwa zvinobudisa kupisa kwakawanda.FR4 PCBs ine yakaderera thermal conductivity, izvo zvinogona kutungamira kune yakakwira tembiricha yekushanda uye inoda mamwe maitiro ekutonhodza.

5. Mari inotariswa:

Mutengo chinhu chakakosha chekutarisa pakusarudza pakati peRogers akadhindwa maseketi uye FR4 PCBs.MaRogers PCB anowanzo kudhura zvakanyanya nekuda kwekuumbwa kwawo kwezvinhu zvakakosha uye kuwedzeredzwa kwekuita.FR4 PCBs inogadzirwa zvakanyanya uye inowanikwa zviri nyore, zvichiita kuti ive inodhura-inoshanda sarudzo yezvese-chinangwa maapplication.

6. Mechanical simba uye kusimba:

Nepo ese ari maviri Rogers PCB uye FR4 PCB aine yakanaka mechani simba uye kusimba, Rogers PCB ine yakakwira mechaniki kugadzikana nekuda kweceramic yakazadzwa laminate.Izvi zvinoita kuti isanyanya kuremara kana kukotama pasi pekumanikidzwa.FR4 PCBs inoramba iri sarudzo yakasimba kune akawanda maapplication, kunyangwe kumwe kusimbiswa kungave kuchidikanwa kune dzimwe nzvimbo dzakaomarara.
Zvichienderana neongororo iri pamusoro, zvinogona kugumiswa kuti sarudzo pakati peRogers PCBs neFR4 PCBs inoenderana nezvinodiwa zvepurojekiti yako.Kana iwe uri kushanda mune yakakwirira frequency application inoda yakanakisa chiratidzo kutendeseka uye yekupisa manejimendi, Rogers PCBs inogona kunge iri sarudzo iri nani, kunyangwe nemutengo wakakwira.Kune rimwe divi, kana iwe uchitsvaga inodhura-inoshanda mhinduro kune general-chinangwa kana yepakati-frequency application, FR4 PCBs inogona kuzadzisa zvaunoda uku ichipa yakanaka mechanic simba.Pakupedzisira, kunzwisisa zvivakwa uye kuumbwa kwezvinhu zvemhando idzi dzePCB kuchakubatsira kuita sarudzo dzine ruzivo dzinosangana nezvido zvepurojekiti yako.
