High Frequency PCB

Usekelo Lwedizayini Nokuthuthukisa Izindleko zama-PCB Avela Kakhulu

Ukudizayina ama-PCB ezinhlelo zokusebenza ze-RF, i-microwave, ne-mmWave kudinga okungaphezu kwezinqubo ezijwayelekile zokuhlela. Kwa-Highleap Electronics, ithimba lethu lonjiniyela lisebenzisana eduze namakhasimende ukuze lenze ubuqotho besignali, ukulawulwa kwe-impedance, nokwenza kahle kusukela esigabeni sokuklama. Sikusiza ukuthi ugweme izingibe ezivamile ezifana ne-vias eningi, amaluphu esignali amade, nokulandela umkhondo okungafanele—ukuqinisekisa ukuthi isakhiwo sakho sisekela ukudluliswa kwesignali ehlanzekile ngisho nakumafrikhwensi e-GHz.

Ukuze sisekele ukusebenza okuthembekile kwe-high-frequency, silandela imihlahlandlela yesakhiwo efakazelwe: ukunciphisa ukuhlangana phakathi kwemigqa yesignali, sisebenzisa ukugoba kokulandela okungu-45° esikhundleni samakhona abukhali, nokunciphisa ukusetshenziswa kwe-soldermask elahlekile emigwaqweni yesignali ebalulekile. Siphinde seluleke ngezinketho zezinto ezinciphisa ukulahleka kwe-dielectric kanye nezinkinga zokuqina kwendawo okubangelwa umphumela wesikhumba kumafrikhwensi aphezulu. Kungakhathaliseki ukuthi idizayini ye-antenna noma ukujikeleza kwe-radar, imininingwane yethu isiza amakhasimende ukuthi agweme izinkinga ze-EMI futhi azuze ukusebenza okungcono kwesignali kuya kumsindo.

I-Highleap iphinde inikeze izixazululo ze-hybrid stack-up ezingabizi kakhulu, ezihlanganisa ama-RF cores aphansi ne-FR-4 ngezendlalelo ezingezona ezibalulekile. Lokhu kulinganisela ukusebenza nokulawulwa kwesabelomali. Kusukela ekuhleleni i-stack-up kuya ekuhlolweni kwe-DFM kanye nokusekelwa kokufanisa i-impedance, silapha ukukuqondisa kuzo zonke izinyathelo—ukusheshisa umjikelezo wakho wokuklama ngenkathi kunciphisa izindleko zokuphindaphinda.

Ukukhethwa kwezinto zokwakha kuyisisekelo sokusebenza kwe-PCB okunemvamisa ephezulu. Kwa-Highleap Electronics, sigcina uhlu oluphethwe kahle lwama-laminate avame kakhulu ukusekela ukwenziwa kweprototyping okusheshayo kanye nokukhiqizwa kwesisindo okuzinzile. Ifektri yethu isebenza eduze nabaphakeli abaziwayo emhlabeni wonke ukuqinisekisa ubuqiniso bezinto zokwakha, ukusebenza kwe-dielectric okuqhubekayo, kanye nokuthola okuthembekile. Sigcina izinto ze-HF PCB zekhwalithi ephezulu njenge-laminate ekhethekile ephansi yokulahlekelwa, i-Taconic, ne-Isola, ezikhethwe ngokucophelela ngenxa yezakhiwo zazo ezinhle kakhulu ze-dielectric kanye nokuqina kokushisa.

Ukusekelwa kwe-Hybrid Stack-Ups kanye ne-Mixed Lamination

Sinikeza ukusekelwa okugcwele kokwakhiwa kwe-PCB eyingxubevange, okuhlanganisa izinto zemvamisa ephezulu ne-FR4 ejwayelekile noma amasistimu wokulahlekelwa okuphansi/prepreg ukulinganisela ukusebenza, izindleko, nokwenziwa. I-CAM yethu enolwazi nonjiniyela bezinqubo bangathuthukisa isitaki sakho sesendlalelo ukuze uqinisekise:

• Ukulawulwa kwe-impedance okuzinzile kuyo yonke imigqa yokudlulisela
• Ukulahlekelwa kokufaka okuphansi kumafrikhwensi aphezulu

• Ukuhambisana nezisindo zethusi ezithile kanye nokuqedwa kwendawo

Funda kabanzi mayelana nezixazululo zethu ze-hybrid stack-up.

Ukuthengwa Kwezinto Ezivumelanayo kanye Nezinto Ezihlinzekwa Ngamakhasimende

Ngokungeziwe ezintweni zethu ezigciniwe zesikhathi eside, siphinde sisekele:

• Ukuthengwa ngokushesha kwama-laminates ashiwo yikhasimende (kuhlanganise nezinto ezingandile noma ezinekhodi ngokwezifiso) ngabasabalalisi abathembekile
• Ukucutshungulwa kwempahla ehlinzekwe yikhasimende (umthwalo) ngokuhambisana nokuphatha okugcwele
• Iziphakamiso zokushintsha izinto ezisuselwe ekulinganeni kukagesi, komshini, nokokushisa ngezindleko noma ukulungiselelwa kwesikhathi sokuhola

Ithimba lethu lokuthola ulwazi lisebenzisana eduze nama-ejenti akhethekile e-laminate aphansi okulahlekelwa, i-Taconic, kanye nezifunda ukuqinisekisa izikhathi zokuhola izinto ezisheshayo kanye neziteshi zokuhlinzeka ngomkhiqizi wokuqala, ikakhulukazi ezintweni ezisekelwe ku-PTFE kanye ne-high-Dk ezinemijikelezo emide yokuthengwa.

Amakhono Okukhiqiza we-PCB Emvamisa Ephezulu

I-Highleap Electronics iletha uhla olubanzi lwamakhono okukhiqiza aklanyelwe izinhlelo zokusebenza zamafrikhwensi aphezulu, ukusuka ku-RF kuye ku-mmWave.
