Iprototyping ye-PCB yosetyenziso lwamaxesha amaninzi

Ukusetyenziswa kwamaza omoya aphezulu kufuna ingqalelo ecokisekileyo kwiinkcukacha kunye neenkqubo zokwenziwa ezichanekileyo. Xa kuziwa kwi-PCB prototyping yezicelo ezinjalo, iimfuno ezithile kufuneka zifezekiswe ukuqinisekisa ukusebenza kakuhle kunye nokuthembeka. I-Capel ineminyaka eyi-15 yamava kwiiprojekthi zebhodi yesekethe kwaye iphuhlise ubuchule obuninzi kwi-PCB prototyping yezicelo eziphezulu zefrikhwensi. Iqela lethu lobuchwephesha lobuchwephesha be-R&D lizibophelele ekuboneleleni ngokukhawuleza nangokuthembekileyo ukwenziwa kweprototype yePCB kubathengi abakwishishini lezicelo ezisebenza ngamaza amaninzi. Ukusuka ekuthengeni ukuya kwimveliso kunye novavanyo, sibonelela ngezisombululo ezithembekileyo zokumisa enye.

Phambi kokuba singene nzulu kwiimfuno ezikhethekileyo ze-PCB prototyping kusetyenziso lwe-frequency ephezulu, masiqale siqonde ukuba kuthetha ukuthini ukuchwetheza okuchanekileyo nokusebenzayo kulo mmandla.Usetyenziso lwe-frequency ephezulu lubandakanya amashishini ahlukeneyo njengezonxibelelwano, i-aerospace, izixhobo zonyango, kunye neenkqubo ezingenazingcingo. Kula mashishini, ukuhanjiswa kwezandi eziphakamileyo kunye nokwamkelwa kubalulekile.

Iprototyping ye-PCB yezicelo ze-frequency ephezulu ifuna uqwalaselo ngononophelo lwemiba ephambili emininzi ukuze kuqinisekiswe imfezeko yophawu olugqibeleleyo, ilahleko encinci, kunye nokuphazamiseka okuncitshisiweyo. Makhe sihlolisise ezinye zeemfuno ngokweenkcukacha:

1. Ukukhetha izinto eziphathekayo: Ukukhetha imathiriyeli ye-PCB echanekileyo ibalulekile kwizicelo ze-high-frequency applications.I-Dielectric constant (Dk), i-dielectric factor (i-Df) kunye ne-thermal conductivity yimiba ephambili yokuqwalasela. Izinto ezifana ne-PTFE okanye i-PTFE laminates zineempawu ezibalaseleyo zombane kunye nelahleko yesignali ephantsi kwiifrikhwensi eziphezulu.

2. Uyilo lwe-stackup: Uyilo olufanelekileyo lwe-stackup lubalulekile ekufezekiseni ukuthintela okulawulwayo.Ukugcina ubukhulu be-dielectric obungaguqukiyo kunye nobungqingqwa be-copper plating kubalulekile kumqondiso wemfezeko. I-impedance elawulwayo inceda ukunciphisa ukubonakaliswa kwezibonakaliso kunye nelahleko, ukuqinisekisa ukuhanjiswa kwedatha ethembekileyo.

3. I-impedance elawulwayo: I-impedance ehambelanayo ibalulekile kwiisignali zedijithali ezinesantya esiphezulu kunye neesekethe zeRF.Iimpawu ezinobunzima obahlukeneyo zinokubangela ukubonakalisa umqondiso, ukuthomalalisa umqondiso, kunye nokuthotywa kokusebenza ngokubanzi. Ukusetyenziswa rhoqo rhoqo, ulawulo oluchanekileyo lwe-impedance ye-PCB yonke luyimfuneko.

4. Iingqimba zomhlaba kunye namandla: Iindlela ezisebenzayo zokumisa zidlala indima ebalulekileyo kuyilo lwe-high-frequency design.Inqwelomoya ezinikeleyo engaguqukiyo ibonelela ngendlela ephantsi yokuthintela ukuqukuqela kokuhamba kwangoku, ukunciphisa ukuphazamiseka komqondiso kunye ne-crosstalk. Ukuhanjiswa kwendiza yamandla okufanelekileyo kunceda ukunika amandla acocekileyo, azinzileyo kwibhodi yonke.

5. I-RF Shielding: Ukuthintela ukuphazamiseka kwe-electromagnetic (EMI) kunye nokuphazamiseka kwerediyo yerediyo (RFI), kubalulekile ukusebenzisa iteknoloji yokukhusela iRF efanelekileyo.Ukukhusela ubhedu, iinkonkxa zokukhusela iRF, kunye nokubekwa kwezixhobo ngobuchule kunokunciphisa kakhulu iziphumo zokuphazamiseka kwangaphandle kunye nokuphucula umgangatho womqondiso.

6. Ukubekwa kwecandelo kunye nendlela: Ukubekwa kwecandelo kunye nendlela kufuneka ziqwalaselwe ngononophelo ukunciphisa ubude belothe kunye nokuphazamiseka komqondiso.Imikhondo emifutshane inciphisa ixesha lokusasazwa komqondiso, ngaloo ndlela inciphisa ithuba lokuthotywa komqondiso. Ukwahlula okufanelekileyo komhlaba kunye nokwahlulwa kwengxolo nako kubalulekile.

7. Ukuwela umqondiso wokuwela: Kwizicelo ze-high-frequency, ukuwela umqondiso wokuwela kufuneka kugwenywe okanye kucwangciswe ngononophelo ukunciphisa nayiphi na impembelelo embi kwimfezeko yomqondiso.Izithuba ezifanelekileyo kunye neendlela zokuzihlukanisa zinceda ukunciphisa ukuphazamiseka komqondiso kunye ne-crosstalk.

8. Uvavanyo kunye nokuQinisekisa: Uvavanyo olungqongqo kunye neenkqubo zokuqinisekisa zibalulekile ukuqinisekisa ukuthembeka kunye nokusebenza kweeprototypes ze-PCB eziphezulu.Iindlela zokuvavanya eziphucukileyo, ezifana ne-time domain reflectometry (TDR), zinokunceda ukuvavanya ukusebenza kunye nokuxilonga nayiphi na imiba yengqibelelo yesiginali.
