4 Layer ENIG FR4+R04350 Mixed Lamination PCB
FR4 + Rogers Kusanganisa Lamination PCB kugadzira Matambudziko
Rimwe rematambudziko makuru muRF / microwave application maitiro ekuona kuti kushivirira chaiko kuri mukati medhizaini kushivirira, kuitira kuti uwane yaunoda kushanda frequency.Rimwe rematambudziko makuru mukugadzirwa kwelamination yezvimiro zvakasanganiswa-kudzvanywa kuve neukobvu hwakafanana pakati pemapanera akasiyana kana kunyange pakati pezvidimbu zvakasiyana.Nekuda kwekuvapo kweakasiyana-siyana emhando yezvinhu zve substrate, kune akasiyana siyana semi-akaporeswa mapepa emhando.
Rogers akasiyana netsika PCB epoxy resin.Iko hakuna girazi fiber pakati uye ndeye ceramic yakavakirwa yakakwirira frequency zvinhu.Pamafambiro edunhu pamusoro pe500MHz, huwandu hwezvinhu zvinowanikwa kune injinjiniya yekugadzira hwakadzikiswa zvakanyanya.Rogers RO4350B zvinhu zvinogona kugadzirwa nyore nyore RF engineering dhizaini maseketi, akadai setiweki matching, transmission line impedance control, etc. Nekuda kwekuderera kwayo dielectric kurasikirwa, R04350B ine bhenefiti pane zvakajairika zvedunhu zvinhu mune yakakwirira frequency application.Iyo dielectric inogara yekushanduka kwekushisa inenge yakadzikira muchinhu chimwe chete.Iyo mvumo zvakare yakagadzikana zvinoshamisa pa3.48 pamusoro pehupamhi frequency renji.3.66.Lopra mhangura foil dhizaini mazano ekuderedza kuisa kurasikirwa.Izvi zvinoita kuti zvinhu zvikodzere kushandiswa kwebroadband.
Zvakanakira Kusanganisa Lamination High Frequency PCB
1. High-frequency PCB ine high density uye yakagadziridzwa chiratidzo.Iyo inopa frequency renji kubva ku500MHz kusvika 2GHz, yakanakira yakakwira-kumhanya dhizaini.
2. Kushandiswa kwepasi pasi kunowedzera kunatsiridza mhando yechiratidzo uye kuderedza magetsi emagetsi.
3.Reduce circuit impedance uye kupa shielding effect.
4. Nekudzikisa kureba pakati pendege uye routing layer, crosstalk inogona kudziviswa
