Yini Eqhuba Izindleko ze-Satellite Messenger PCBA
Izindleko zivame ukulawulwa yi-satellite/GNSS BOM, ukwakhiwa kwe-RF, ihadiwe yesivikelo/ye-antenna, ibhethri kanye nokuxhumana okuqinile, ubuningi bokuhlanganiswa, uhlelo/ukunikezwa kanye nesikhathi sokuhlola. I-RF laminate ekhethekile kufanele icashunwe kuphela lapho i-stack-up ekhishwe idinga khona; ukuba khona komsakazo we-satellite ngokwakho akudingi i-microwave laminate kuzo zonke izingqimba.
Ukuze uthole ikhotheshini, nikeza i-Gerber/ODB++, amanothi okuhlanganisa kanye nokuvimba, i-BOM, imininingwane yemojula yesathelayithi, imidwebo ye-antenna/RF, amafayela omshini, imininingwane yebhethri, iphakheji ye-firmware/yokunikeza, inqubo yokuhlola, ukulebula/imithetho yochungechunge kanye nobuningi. Ikhasi lokulawula ikhwalithi ye-Highleap PCB lifingqa ifilosofi yokuhlola engasetshenziswa kububanzi bokukhiqiza.
Umkhakha Wokukhiqiza Wehadiwe Esetshenziswa Ngaphandle Kokumbozwa Kweselula
Ukukhiqizwa kwezithunywa zesathelayithi kunamandla kakhulu lapho iphakheji yokukhiqiza yenza imingcele yesevisi icace. I-Highleap idinga idatha ye-PCB ekhishwe, i-BOM, imininingwane yemojula yesathelayithi/GNSS, imidwebo ye-antenna ne-RF, imininingwane yebhethri, amafayela omshini, imiyalelo ye-firmware noma yokuhlinzeka, imithetho yokulebula, amasimu okulandelela kanye nenqubo yokuhlola evunyiwe. Noma yimuphi umsebenzi wenethiwekhi ebukhoma osetshenziswa ekuqinisekiseni kufanele ulandele uhlelo lwesevisi yekhasimende kanye nezilawuli zokuhlola.
Izindleko kufanele zakhiwe ngehadiwe yangempela. Izingxenye zesathelayithi ne-GNSS, ukwakhiwa kwe-RF, izihlangu, izixhumi ze-antenna, ihadiwe yebhethri, ukuxhumana okuqinile, uhlelo kanye nesikhathi sokuhlola kungabaluleke kakhulu kune-PCB engenalutho uqobo. I-RF laminate ekhethekile ifanelekile kuphela uma izidingo zokuxhuma nokulahlekelwa ezikhishwe zidinga lokho.
Ngemikhiqizo ehloselwe ukusebenza ngale kokumbozwa kwamaselula, isiyalo sokukhiqiza siyingxenye yokuthembeka komkhiqizo. Ibhodi elithumela ezinyangeni ngemuva kokufaneleka kufanele lilondoloze inani elifanayo le-RF, indlela yokuhlinzeka kanye nezilawuli zokuhlanganisa njengebhodi eladlula ukuqinisekiswa kwekhasimende. Yilokho ukuqhubeka okufanele kucelwe i-Highleap ukuthi icaphune.

Ungasithola kanjani isilinganiso sama-PCB
Ake siqhube ukuhlaziywa kwe-DFM/DFA bese sibuyela kuwe nombiko. Ungalayisha amafayela akho ngokuphephile ngewebhusayithi yethu. Sidinga ulwazi olulandelayo ukuze sikunike isilinganiso:
-
- Gerber, ODB++, noma .pcb, spec.
- Uhlu lwe-BOM uma udinga ukuhlangana
- Ubuningi
- Isikhathi sokushintsha
Ngezinsizakalo ze-PCBA, sicela unikeze i-BOM yakho (I-Bill of Materials) kanye nanoma yimiphi imiyalelo ethile yomhlangano. Siphinde sinikeze ukuhlaziya kwe-DFM/DFA ukuze uthuthukise imiklamo yakho ukuze yenziwe futhi ihlanganiswe, ukuqinisekisa inqubo yokukhiqiza eshelelayo.
