Kana zvasvika kune zvigadzirwa zvemagetsi uye akadhindwa edunhu mabhodhi (PCBs), chinhu chakakosha chinotariswa nemainjiniya nevagadziri ndeyekukwirisa rated frequency.Iyi chiyero inosarudza iyo yakakwira frequency iyo dunhu rinogona kushanda zvakavimbika pasina kurasikirwa kunoonekwa kana kuderedzwa kwechiratidzo.Mune ino blog post, isu tichaongorora kukosha kweiyo yakanyanya frequency rating yekukurumidza kushandura prototype PCB mabhodhi uye kukurukura kuti zvinokanganisa sei dhizaini nekuita kwemidziyo yemagetsi.
Maximum rated frequency ndiyo yakakosha parameter kana uchibata neakakwira-kumhanya uye akaomarara emagetsi masisitimu.Inoreva kuwanda kweiyo frequency iyo chiratidzo chinogona kufambiswa kuburikidza nePCB pasina kukanganisa kana kurasikirwa kwechiratidzo.Chiyero ichi chinotonyanya kukosha kana tasvika pakukurumidza kutendeuka prototype PCB mabhodhi, sezvo mabhodhi aya anowanzo shandiswa mukuvandudza uye kuyedza zvikamu zvemidziyo mitsva yemagetsi.
Rapid Turnaround Prototype PCB mabhodhi anogadzirwa nechinguva chidiki chekuchinja uye anowanzo shandiswa sehumbowo hwepfungwa, kuyedzwa, uye yekutanga dhizaini dhizaini.Chinangwa chavo ndechekuona kuti chigadzirwa chekupedzisira chinoshanda sezvinotarisirwa chisati chapinda mukugadzirwa kwakazara.Naizvozvo, ivo vanofanirwa kushanda zvakavimbika pane inodiwa frequency kuratidza nemazvo kuita kwechigadzirwa chekupedzisira.
Iyo yakawanda yakatemerwa frequency yekukurumidza-kutendeuka prototyping PCB board inobatwa nezvinhu zvakasiyana, zvinosanganisira PCB zvinhu, dhizaini dhizaini, kutapurirana mitsara maitiro, uye kuvapo kwechero kukanganisa kana ruzha masosi.Kusarudzwa kwezvinhu kwakakosha nekuti mamwe marudzi ePCB anogona kubata ma frequency epamusoro zvakanyanya kupfuura mamwe.High-frequency materials senge Rogers 4000 Series, Teflon, kana PTFE laminates anowanzo shandiswa kukurumidza kushandura prototype PCBs kuti iwane hukuru hwepamusoro pama frequency akakwira.
Dhizaini dhizaini inoitawo basa rakakosha mukuona iyo yakanyanya frequency rating yePCB board.Yakakodzera impedance inofananidzwa, inodzorwa kuteedzera kureba, uye kuderedza chiratidzo chekuratidzira kana crosstalk matanho akakosha ekuona kuti masaini anopararira zvinobudirira pasina kudzikisira.Yakanyatsogadzirwa PCB dhizaini inoderedza njodzi yekukanganiswa kwechiratidzo uye inochengetedza yakakwirira-frequency chiratidzo chekuvimbika.
Mamiriro emutsetse wekutapurirana, senge hupamhi hwekutsvagira, ukobvu, uye chinhambwe kubva kundege yepasi, zvakare zvinokanganisa huwandu hwakayerwa.Aya ma paramita anotarisisa hunhu hunokanganisa tambo yekutapurirana uye inofanirwa kuverengerwa zvakanyatsoenderana neinodiwa frequency.Kukundikana kuita izvi kunogona kukonzera zviratidzo zvechiratidzo uye kurasikirwa kwechiratidzo chekutendeseka.
Pamusoro pezvo, kuvapo kwekupindira kana ruzha masosi kunogona kukanganisa iyo yakanyanya kurongeka frequency yekukurumidza-kutendeuka prototype PCB board.Kudzivirira kwakakodzera uye nzira dzekudzika dzinofanirwa kushandiswa kuderedza mhedzisiro yekunze kweruzha masosi uye kuve nechokwadi chekushanda kwakavimbika pamafafitera epamusoro.
Kazhinji, iyo yakanyanya kuyerwa frequency yekukurumidza-kutendeuka prototyping PCB mabhodhi anogona kubva kune mashoma megahertz kusvika akati wandei gigahertz, zvichienderana nedhizaini yedhizaini uye zvinodiwa zvekushandisa.Vane ruzivo vagadziri vePCB uye mainjiniya vanofanirwa kubvunzurudzwa kuti vaone yakanyanya kunaka frequency rating kune yako chaiyo purojekiti.
Muchidimbu, iyo yakanyanya rated frequency ndiyo yakakosha parameter kana uchifunga nekukurumidza-turn prototyping PCB board.Iyo inosarudza iyo yakanyanya frequency iyo chiratidzo chinogona kufambiswa zvakavimbika pasina kukanganisa kana kurasikirwa kwechiratidzo.Nekushandisa yakakwira-frequency zvinhu, uchishandisa iyo chaiyo dhizaini dhizaini, manejimendi ekufambisa mitsara, uye kudzikisira kupindira, mainjiniya anogona kuona kuti kukurumidza-kutendeuka prototype PCB mabhodhi anoshanda nekuvimbika kwakanyanya pane inodiwa frequencies.
