I-High Frequency Material PCB Assembly

I-High Frequency Material PCB Assembly

I-Shenzhen Cirket Electronics Co., Ltd, isixazululo sakho sokuma okukodwa sazo zonke izidingo zakho ze-OEM ne-ODM PCB ne-PCBA. Isungulwe ngo-2009, sesikhule saba umhlinzeki oholayo wezinsizakalo ezigcwele ze-turnkey kumakhasimende emhlabeni jikelele. Ngemigqa ye-SMT engu-9 kanye nemigqa emi-2 ye-DIP, sinekhono lokusingatha zonke izici zenqubo yokukhiqiza, kusukela ekuthuthukisweni nasekuthengeni izinto ezibonakalayo, ukuya ekuhlanganiseni nasekuphatheni izinto.


I-PCB enefrikhwensi ephezulu (Ibhodi Lesekhethi Ephrintiwe) ibhekisela ohlotsheni lwebhodi lesekethe elakhelwe ukusebenza kumaza omsakazo (RF) noma amaza ama-microwave. Lawa maza ngokuvamile asukela kumakhulu ama-megahertz (MHz) kuya kuma-gigahertz (GHz) ambalwa futhi avame ukusetshenziswa ezinhlelweni zokuxhumana ezingenazintambo, amasistimu e-radar, ukuxhumana ngesathelayithi, kanye nokucubungula isignali yedijithali enesivinini esikhulu.

    Ama-PCB anemvamisa ephezulu anezici ezimbalwa ezihlukile nokucatshangelwa kwesakhiwo uma kuqhathaniswa nama-PCB ajwayelekile:

    1. Ukukhetha Okubalulekile: Ama-PCB anemvamisa ephezulu avamise ukusebenzisa izinto ezikhethekile ezinezakhiwo zikagesi ezinhle kakhulu ukuze kuncishiswe ukulahleka kwesignali nokugcina ubuqotho besignali kumafrikhwensi aphezulu. Izinto ezijwayelekile zifaka ama-PTFE (Polytetrafluoroethylene) ama-substrates afana ne-Teflon, kanye nama-laminates amafrikhwensi aphezulu afana ne-FR-4 anezici ze-dielectric ezithuthukisiwe.

    2. I-Dielectric Yokulahlekelwa Okuphansi:Impahla ye-dielectric esetshenziswa kuma-PCB anemvamisa ephezulu ikhethelwa i-low dielectric constant (Dk) kanye ne-low dissipation factor (Df), esiza ukunciphisa ukuncishiswa kwesignali nokuhlanekezela kumafrikhwensi aphezulu.

    3. Ukuphazamiseka okulawulwayo: Ama-PCB anemvamisa ephezulu ngokuvamile adinga ukulawulwa okunembile kwe-impedance ukuze kuqinisekiswe ukudluliswa kwesignali okusebenzayo kanye nokunciphisa ukubonakaliswa. Landelela ububanzi, ubukhulu be-dielectric, nokulungiselelwa kwesitaki sesendlalelo kudizayinelwe ngokucophelela ukuze kuzuzwe isici esifiselekayo.

    4. Ukugawula kanye nokuvikela: Amasu afanele okubeka phansi kanye nokuvikela abalulekile ekwakhiweni kwe-PCB yemvamisa ephezulu ukuze kuncishiswe ukuphazamiseka kwe-electromagnetic (EMI) nokuqinisekisa ubuqotho besignali. Izindiza eziphansi, imikhondo yokuqapha, nezingqimba ezivikelayo zisetshenziselwa ukunciphisa i-crosstalk nomsindo.

    5. Idizayini yolayini wokudlulisa: Amasiginali wefrikhwensi ephezulu kuma-PCB aziphatha kakhulu njengezintambo zokudlulisela kunezintambo ezilula zikagesi. Izimiso zokuklama kolayini wokudlulisa, njengemigqa ye-impedance elawulwayo, ukulungiswa kwe-microstrip noma i-stripline, nezindlela zokufanisa i-impedance, zisetshenziswa ukuze kuthuthukiswe ubuqotho besignali kanye nokunciphisa ukuwohloka kwesignali.

    6. Ukubekwa Kwengxenye kanye Nomzila:Ukubekwa ngokucophelela nomzila wezingxenye nokulandelelwa kwesignali kubalulekile ekwakhiweni kwe-PCB yemvamisa ephezulu ukuze kuncishiswe ubude bendlela yesiginali, kugwenywe ukugoba okubukhali, nokunciphisa imithelela ye-parasitic engonakalisa ikhwalithi yesignali.

    7. Izixhumi ze-High-Frequency:Izixhumi ezisetshenziswa kuma-PCB anemvamisa ephezulu zikhethwa ngenxa yezimpawu zazo ezihambisana ne-impedance kanye nokulahlekelwa kokufakwa okuphansi ukuze kuncishiswe ukuboniswa kwesignali nokugcina ubuqotho besignali kumafrikhwensi aphezulu.

    8. Ukuphatha Okushisayo: Kwezinye izinhlelo zokusebenza ze-high-frequency yamandla aphezulu, ukuphathwa kwe-thermal kuba okubalulekile ukuvimbela ukushisisa kwezingxenye kanye nokugcina ukusebenza okuthembekile. Osinki bokushisa, i-thermal vias, kanye namasu okuphatha okushisayo asetshenziswa ukuze kukhishwe ukushisa ngempumelelo.
