Umfanekiso 2. I-PCB Enemvamisa Ephakeme
3. Izinto Ezifihliwe Zomugqa Nokungaqondi Okuvamile Ezicaphunweni ze-HF PCB
3.1 Izindleko ze-NRE (Ubunjiniyela Obungaphindwaphindwa)
Ama-oda e-HF avame ukufaka i-NRE ye: ukumodela kwe-stackup/ukulingiswa kwe-impedance, ukukhiqizwa kwamathuluzi esithombe, ukudalwa kobuciko bokunxephezela i-etch, ukwakheka kwekhuphoni ye-impedance, kanye nesikhathi sobunjiniyela be-first-article. I-NRE ivame ukusuka ku-$200–$800 ye-laminate hybrid ekhethekile enezingqimba ezine, kuze kufike ku-$1,500+ ye-PTFE stackups eyinkimbinkimbi enezingqimba eziningi. Abanye abakhiqizi bahlanganisa i-NRE entengo yeyunithi ngayinye (okwenza ingabonakali kodwa isakhona); abanye bayibeka ngokwehlukana.
Uma uqhathanisa amanani, cela umenzi ngamunye ukuthi ahlukanise i-NRE ngokwehlukana. Isilinganiso esine-$500 NRE kanye ne-$25/ibhodi asifani nesilinganiso esine-$0 NRE kanye ne-$30/ibhodi — esokuqala sishibhile kumabhodi ayi-100 ($3,000 iyonke) kodwa sibiza kakhulu kumabhodi angama-20 ($1,000 vs. $600).
3.2 Ukuguquguquka Kwentengo Yezinto Ezibalulekile
Amanani e-laminate e-laminate akhethekile anezindleko eziphansi ahlukahluka ngokuya ngezindleko zezinto zokwakha kanye nesidingo. Isilinganiso esisebenza izinsuku ezingama-30 singase singabi khona uma amanani ezinto zokwakha enyuka ngaphambi kokuba i-PO yakho ikhishwe. Cacisa: Ingabe intengo yezinto zokwakha ecashuniwe ivaliwe isikhathi sokusebenza? Ingabe kukhona isigaba sokulungiswa kwentengo yezinto zokwakha kuma-oda abekwe ngemuva kokuphelelwa yisikhathi kwesilinganiso? Kuma-oda amakhulu okukhiqiza, abanye abakhiqizi banikeza i-price lock yezinto zokwakha ngokwamukela idiphozithi yezinto zokwakha. Izidingo ze-RT/duroid 6002 stackup kanye ne-quotation kufanele zikhombe i-laminate eqondile, ukujiya okuqediwe, isisindo sethusi kanye nokuqinisekiswa kwe-impedance okudingekayo.
3.3 Izinkolelo Zokusetshenziswa Kwephaneli
Isilinganiso sithatha ukwakheka kwephaneli ethile. Uma umenzi ephinda abekwe kabusha ngemuva kokuthola i-oda lakho (ngenxa yezici zohlaka lwebhodi, izidingo zethebhu ephukile, noma ukubekwa kwekhuphoni), intengo yeyunithi ngayinye ingashintsha. Cela umenzi ukuthi afake ukwakheka kwephaneli yakhe nesilinganiso - lokhu kukuvumela futhi ukuthi uqinisekise ukuthi indlela yokubeka ikhuphoni kanye nendlela yokuhlukanisa ihlangabezana nezidingo zakho.
3.4 Umehluko Wezinga Lokuhlola
“Ukuhlolwa kukagesi kufakiwe” akusho into efanayo kubakhiqizi:
- Ukuqhubeka + ukuhlukaniswa kuphela: Ayiqinisekisi ukuvulwa noma ukufiphaza. Ayiqinisekisi ukuvimba. Lokhu kuncane kakhulu.
- + Ukuhlolwa kwekhuphoni le-Impedance (ngephaneli ngayinye): Ukulinganiswa kwe-TDR kumakhuphoni avela kuphaneli ngayinye. Okujwayelekile kwamabhodi e-HF.
- + Ukuhlolwa kwe-impedance yebhodi engu-100%: Ibhodi ngalinye lilinganisiwe. Libiza kakhulu. Liyadingeka ukuze kube neklasi 3/ukuthembeka okuphezulu.
- + Ukulinganiswa kokulahlekelwa kokufakwa kwe-VNA: Ukulinganiswa kwepharamitha ye-S ngemvamisa yokusebenza kumakhuphoni okuhlola. Kuyatholakala uma kuceliwe, hhayi okujwayelekile.
