PCB prototyping yeakakwira frequency application

High frequency application inoda kutarisisa kune zvakadzama uye nemazvo ekugadzira maitiro. Kana zvasvika kuPCB prototyping yezvishandiso zvakadaro, zvinodiwa chaizvo zvinofanirwa kusangana kuti ive nechokwadi chekuita kwakakwana uye kuvimbika. Capel ane makore gumi nemashanu eruzivo mumapurojekiti ebhodhi redunhu uye akagadzira hunyanzvi hwakakura muPCB prototyping yeakakwira frequency application. Yedu nyanzvi tekinoroji R&D timu yakazvipira kupa inokurumidza uye yakavimbika PCB prototype kugadzira kune vatengi muyakakwira-frequency application indasitiri. Kubva pakutenga kusvika pakugadzira uye kuyedzwa, isu tinopa imwe-stop yakavimbika mhinduro.

Tisati tanyura mune izvo chaizvo zvinodikanwa zvePCB prototyping mune yakakwirira-frequency application, ngatitangei tinzwisise izvo zvakarurama uye zvine hungwaru prototyping inorevei mumunda uyu.High-frequency applications inosanganisira maindasitiri akasiyana seyekufonerana, aerospace, zvekurapa, uye mawaya masisitimu. Mune aya maindasitiri, yakakwirira frequency chiratidzo chekufambisa uye kugamuchira kwakakosha.

PCB prototyping ye-high-frequency application inoda kunyatsotariswa kwezvinhu zvakati wandei kuti ive nechokwadi chekuvimbika kwechiratidzo, kurasikirwa kudiki, uye kukanganiswa kukanganiswa. Ngationgororei zvimwe zvezvinodiwa zvakadzama:

1. Kusarudzwa kwezvinhu: Kusarudza yakakodzera PCB zvinhu kwakakosha kune yakakwirira-frequency application.Dielectric constant (Dk), dissipation factor (Df) uye thermal conductivity zvinhu zvinokosha zvekufunga nezvazvo. Zvishandiso zvakaita sePTFE kana PTFE laminates zvine yakanakisa magetsi emagetsi uye yakaderera chiratidzo kurasikirwa pakakwirira.

2. Stackup dhizaini: Yakakodzera stackup dhizaini yakakosha pakuwana inodzorwa impedance.Kuchengetedza kuenderana dielectric ukobvu uye mhangura yeplating ukobvu kwakakosha kuratidza kuvimbika. Kudzora impedance kunobatsira kuderedza zviratidzo zvechiratidzo uye kurasikirwa, kuve nechokwadi chekufambisa data.

3. Kudzora Impedance: Impedance inofananidzwa yakakosha kune yakakwirira-kumhanya masaini edhijitari uye RF maseketi.Masaini ane akasiyana impedances anogona kukonzera kuratidzwa kwechiratidzo, kuderedzwa kwechiratidzo, uye kuderera kwekuita kwese. Kune yakakwirira frequency application, chaiyo impedance control yePCB yese inodiwa.

4. Zvikamu zvepasi uye simba: Nzira dzekugadzirisa dzinoshanda dzinoita basa rinokosha mukugadzirwa kwepamusoro-frequency.Ndege yakatsaurirwa yakatsaurirwa pasi inopa yakaderera-impedance nzira yekudzoka yekuyerera kwazvino, kuderedza kupindira kwechiratidzo uye crosstalk. Kugovera kwakakodzera kwendege yemagetsi kunobatsira kupa yakachena, yakagadzikana simba mubhodhi rose.

5. RF Shielding: Kudzivirira kukanganiswa kwemagetsi (EMI) uye redhiyo frequency interference (RFI), zvakakosha kushandisa zvakakodzera RF shielding teknolojia.Copper shielding, RF inodzivirira magaba, uye nehurongwa hwekuiswa kwezvikamu zvinogona kuderedza zvakanyanya mhedzisiro yekukanganiswa kwekunze uye kugadzirisa chiratidzo chemhando.

.Mapfupi anoteedzera anoderedza chiratidzo chekuparadzira nguva, nekudaro ichidzikisa mukana wekuderera kwechiratidzo. Kuparadzaniswa kwevhu kwakafanira uye kuparadzaniswa kweruzha kunokosha zvakare.

7. Signal trace crossings: Mu-high-frequency applications, chiratidzo chekutsvaga kuyambuka kunofanira kudziviswa kana kunyatsorongwa kuderedza chero kukanganisa kwakashata pakuvimbika kwechiratidzo.Yakakodzera nzvimbo uye nzira dzekuzviparadzanisa nadzo dzinobatsira kuderedza kukanganiswa kwechiratidzo uye crosstalk.

8. Kuedza uye Kusimbisa: Kuedza kwakasimba uye maitiro ekugadzirisa anokosha kuti ave nechokwadi chekuvimbika uye kushanda kwepamusoro-frequency PCB prototypes.Maitiro epamberi ekuyedza, akadai senguva domain reflectometry (TDR), anogona kubatsira kuongorora mashandiro uye kuongorora chero nyaya dzechiratidzo.

PaCapel, isu tinonzwisisa kukosha kweizvi chaizvo zvinodiwa zvePCB prototyping mune yakakwirira frequency application. Nemakore edu gumi nemashanu eruzivo uye nehunyanzvi tekinoroji R&D timu, isu tave nehunyanzvi hwekugadzira akavimbika uye anoshanda ePCB prototypes. Yedu-yekumira mhinduro dzakavimbika dzinosanganisira kutenga, kugadzira uye kuyedzwa, kuvimbisa kugutsikana kwevatengi.

Muchidimbu, PCB prototyping ye-high-frequency application inoda kutarisisa kune zvakadzama uye kutevedzera zvinodiwa chaizvo.Zvishandiso, stackup dhizaini, impedance control, nzira dzekumisa pasi, RF dziviriro, dhizaini yechikamu uye maitiro ebvunzo zvese zvinotora basa rakakosha mukuona kuita kwakakwana.Unyanzvi hwaCapel muPCB prototype kugadzirwa kweakakwira frequency application inoita kuti tive mudiwa akakodzera kumakambani ari muindasitiri yekushandiswa kwema frequency. Vimba nesu kuendesa nekukurumidza, yakavimbika PCB prototypes inosangana nezvinodiwa zvako uye inodarika zvaunotarisira.
