High Frequency Material PCB Assembly

High Frequency Material PCB Assembly

I-Shenzhen Cirket Electronics Co., Ltd, isisombululo sakho sokumisa esinye kuzo zonke ii-OEM zakho kunye ne-ODM PCB kunye neemfuno zePCBA. Isekwe ngo-2009, siye sakhula saba ngumboneleli okhokelayo weenkonzo ezipheleleyo zokujika kubathengi kwihlabathi liphela. Ngemigca ye-SMT eyi-9 kunye nemigca emi-2 ye-DIP, sinamandla okuphatha yonke inkalo yenkqubo yokuvelisa, ukusuka ekuphuhliseni nasekuthengeni izinto eziphathekayo, ukuya kwindibano kunye ne-logistics.


I-PCB ye-high-frequency (iBhodi yeSekethe eShicileleyo) ibhekiselele kudidi lwebhodi yesekethe eyenzelwe ukusebenza kwiifrikhwensi zerediyo (RF) okanye ii-microwave frequencies. Ezi frikhwensi ziqhele ukuqala kumakhulu eemegahertz (MHz) ukuya kwiigigahertz ezininzi (GHz) kwaye ziqhele ukusetyenziswa kwiinkqubo ezifana neenkqubo zonxibelelwano ezingenazingcingo, iinkqubo zeradar, unxibelelwano ngesathelayithi, kunye nesantya esiphezulu sokwenziwa komqondiso wedijithali.

    Ii-PCBs ezikwi-frequency ephezulu zineempawu ezininzi ezahlukileyo kunye noqwalaselo loyilo xa kuthelekiswa neePCB eziqhelekileyo:

    1. Ukukhethwa kwezinto: Ii-PCB ze-frequency ephezulu zihlala zisebenzisa izixhobo ezikhethekileyo ezineempawu ezibalaseleyo zombane ukunciphisa ilahleko yomqondiso kunye nokugcina imfezeko yomqondiso kumaza aphezulu. Izinto eziqhelekileyo ziquka i-PTFE (i-Polytetrafluoroethylene) i-substrates efana neTeflon, kunye ne-high-frequency laminates njenge-FR-4 eneempawu eziphuculweyo ze-dielectric.

    2. Ilahleko ephantsi yeDielectric:Isixhobo se-dielectric esisetyenziswe kwi-PCB ephezulu-frequency ikhethwa kwi-dielectric constant constant (Dk) kunye ne-low dissipation factor (Df), enceda ukunciphisa ukutshatyalaliswa komqondiso kunye nokuphazamiseka kwiifrikhwensi eziphezulu.

    3. UZinzo oluLawulwayo: Ii-PCB ze-Frequency High-frequency zihlala zifuna ulawulo oluchanekileyo lwe-impedance ukuqinisekisa ukuhanjiswa komqondiso okusebenzayo kunye nokunciphisa ukubonakaliswa. Umkhondo ububanzi, ubukhulu be-dielectric, kunye nolungelelwaniso lwe-stackup luyilwe ngononophelo ukufezekisa i-impedance yeempawu ezifunekayo.

    4. Ukumhlaba kunye nokuKhusela: Iindlela ezifanelekileyo zokubeka umhlaba kunye neendlela zokukhusela zibalulekile kuyilo lwePCB olukwi-frequency ephezulu ukunciphisa uphazamiseko lwe-electromagnetic (EMI) kunye nokuqinisekisa imfezeko yomqondiso. Iinqwelomoya ezisezantsi, umkhondo wokugada, kunye neengqimba ezikhuselayo zisetyenziselwa ukunciphisa i-crosstalk kunye nengxolo.

    5. UYilo lweNdlela yoThutho: Imiqondiso yefrikhwensi ephezulu kwii-PCB ziziphatha njengeentambo zothumelo kuneendlela ezilula zombane. Imigaqo yoyilo lomgca wothumelo, njengeentambo ezilawulwayo ze-impedance, i-microstrip okanye ulungelelwaniso lwe-stripline, kunye nobuchule bokuthelekisa i-impedance, zisetyenziselwa ukwandisa imfezeko yomqondiso kunye nokunciphisa ukuthotywa komqondiso.

    6. Ukubekwa kweCandelo kunye noNdlela:Ukubekwa ngononophelo kunye nomzila wamacandelo kunye nezalathisi zesignali zibalulekile kuyilo lwe-PCB olukwi-frequency ephezulu ukunciphisa ubude bendlela yomqondiso, ukuphepha ukugoba okubukhali, kunye nokunciphisa iziphumo zeparasitic ezinokuthobisa umgangatho wesignali.

    7. Iziqhagamshelo eziPhezulu-Frequency:Iziqhagamshelo ezisetyenziswa kwii-PCB ezikwi-frequency ephezulu zikhethwa ngenxa yeempawu ezihambelana ne-impedance kunye nelahleko ephantsi yokufaka ukunciphisa ukubonakalisa umqondiso kunye nokugcina imfezeko yesiginali kwiifrikhwensi eziphezulu.

    8. Ulawulo lweThermal: Kwezinye izicelo eziphezulu ze-high-frequency, ulawulo lwe-thermal luba lubalulekile ekuthinteleni ukufudumeza kwamacandelo kunye nokugcina ukusebenza okuthembekileyo. I-Heat sinks, i-thermal vias, kunye neendlela zokulawula ukushisa zisetyenziselwa ukuchitha ubushushu ngokufanelekileyo.
