I-PCB prototyping yezinhlelo zokusebenza zemvamisa ephezulu

Izinhlelo zokusebenza zemvamisa ephezulu zidinga ukunakwa okucophelela kwemininingwane kanye nezinqubo zokukhiqiza ezinembayo. Uma kuziwa ku-PCB prototyping yezinhlelo ezinjalo, izimfuneko ezithile kufanele kuhlangatshezwane nazo ukuze kuqinisekiswe ukusebenza okuphelele nokwethembeka. U-Capel uneminyaka engu-15 yesipiliyoni kumaphrojekthi webhodi lesifunda futhi usethuthukise ubuchwepheshe obuningi ku-PCB prototyping yezinhlelo zokusebenza zemvamisa ephezulu. Ithimba lethu lezobuchwepheshe le-R&D lizibophezele ekuhlinzekeni ukukhiqiza kwe-PCB okushesha nokuthembekile kumakhasimende embonini yezicelo esebenza imvamisa ephezulu. Kusukela ekuthengeni izinto kuye ekukhiqizeni nasekuhloleni, sinikeza izixazululo ezinokwethenjelwa endaweni eyodwa.

Ngaphambi kokuthi singene sijule ezidingweni ezithile ze-PCB prototyping kuzinhlelo zokusebenza zamafrikhwensi aphezulu, ake siqale siqonde ukuthi kusho ukuthini i-prototyping enembile nephumelelayo kulo mkhakha.Izinhlelo zokusebenza ezisebenza ngamaza aphezulu zifaka izimboni ezihlukene njengezokuxhumana, i-aerospace, imishini yezokwelapha, namasistimu angenantambo. Kulezi zimboni, ukudluliswa kwesignali yemvamisa ephezulu kanye nokwamukela kubalulekile.

I-PCB prototyping yezinhlelo zokusebenza zemvamisa ephezulu idinga ukucatshangelwa ngokucophelela kwezinto ezimbalwa ezibalulekile ukuze kuqinisekiswe ubuqotho besignali obufanele, ukulahlekelwa okuncane, nokuphazamiseka okuncishisiwe. Ake sihlole ezinye zezimfuneko ngokuningiliziwe:

1. Ukukhetha impahla: Ukukhetha okubalulekile kwe-PCB kubalulekile ezinhlelweni zokusebenza zamafrikhwensi aphezulu.I-Dielectric constant (Dk), i-dielectric factor (i-Df) kanye ne-thermal conductivity yizici ezibalulekile okufanele zicatshangelwe. Izinto ezifana ne-PTFE noma i-PTFE laminates zinezakhiwo zikagesi ezinhle kakhulu nokulahlekelwa kwesignali ephansi kumafrikhwensi aphezulu.

2. Idizayini yesitaki: Idizayini efanele yesitaki ibalulekile ukuze kuzuzwe ukuvinjelwa okulawulwayo.Ukugcina ukuqina kwe-dielectric okungaguquki kanye nokuqina kwe-copper plating kubalulekile ekuboniseni ubuqotho. I-impedance elawulwayo isiza ukunciphisa ukubonakaliswa kwesignali nokulahlekelwa, iqinisekisa ukudluliswa kwedatha okuthembekile.

3. I-impedance elawulwayo: Ukufanisa ukuvimbela kubalulekile kumasignali edijithali anesivinini esikhulu namasekhethi e-RF.Amasignali anama-impedance ahlukene angabangela ukubonakaliswa kwesignali, ukuncishiswa kwesignali, kanye nokuwohloka kokusebenza okuphelele. Kuzinhlelo zokusebenza zemvamisa ephezulu, ukulawulwa okuqondile kwe-impedance kwayo yonke i-PCB kuyadingeka.

4. Izendlalelo eziphansi nezinamandla: Izindlela zokubeka phansi ezisebenzayo zidlala indima ebalulekile ekwakhiweni kwefrikhwensi ephezulu.Indiza yaphansi ezinikele engaguquki ihlinzeka ngendlela yokubuya enezithiyo eziphansi zokugeleza kwamanje, inciphise ukuphazamiseka kwesignali kanye ne-crosstalk. Ukusatshalaliswa okufanele kwendiza yamandla kusiza ukunikeza amandla ahlanzekile, azinzile kulo lonke ibhodi.

5. Ukuvikela i-RF: Ukuvimbela ukuphazamiseka kwe-electromagnetic (EMI) kanye nokuphazamiseka kwefrikhwensi yomsakazo (RFI), kubalulekile ukusebenzisa ubuchwepheshe obufanele bokuvikela i-RF.Ukuvikela ithusi, amathini okuvikela i-RF, kanye nokubekwa kwamasu kwezingxenye kunganciphisa kakhulu imiphumela yokuphazamiseka kwangaphandle futhi kuthuthukise ikhwalithi yesiginali.

6. Ukubekwa kwengxenye kanye nomzila: Ukubekwa kwengxenye kanye nendlela kufanele kucatshangelwe ngokucophelela ukuze kuncishiswe ubude bomthofu kanye nokuphazanyiswa kwesignali.Ukulandelela okufushane kunciphisa isikhathi sokusakazeka kwesignali, ngaleyo ndlela kunciphisa ithuba lokuwohloka kwesignali. Ukuhlukaniswa okufanele komhlabathi nokuhlukaniswa komsindo nakho kubalulekile.

7. Iziphambano zokulandelela isignali: Kuzinhlelo zokusebenza zemvamisa ephezulu, ukuwela isignali yokulandelela kufanele kugwenywe noma kuhlelwe ngokucophelela ukuze kuncishiswe noma yimuphi umthelela omubi ekuthembekeni kwesignali.Izikhala ezifanele kanye namasu okuhlukanisa asiza ukunciphisa ukuhlanekezela kwesignali kanye ne-crosstalk.

8. Ukuhlola Nokuqinisekisa: Izinqubo eziqinile zokuhlola nokuqinisekisa zibalulekile ukuze kuqinisekiswe ukwethembeka nokusebenza kwama-prototypes e-PCB anemvamisa ephezulu.Amasu okuhlola athuthukile, njenge-time domain reflectometry (TDR), angasiza ukuhlola ukusebenza nokuxilonga noma yiziphi izinkinga zesignali yobuqotho.

E-Capel, siyakuqonda ukubaluleka kwalezi zidingo eziqondile ze-PCB prototyping ezinhlelweni zokusebenza zemvamisa ephezulu. Ngesipiliyoni sethu seminyaka engu-15 kanye nethimba lethu le-R&D lochwepheshe, sifunde ubuciko bokukhiqiza ama-PCB athembekile nasebenza kahle. Izixazululo zethu ezinokwethenjelwa okukodwa zifaka phakathi ukuthenga, ukukhiqiza nokuhlola, ukuqinisekisa ukwaneliseka kwamakhasimende.

Ngokufigqiwe, I-PCB prototyping yezinhlelo zokusebenza zefrikhwensi ephezulu idinga ukunakwa emininingwaneni kanye nokuhambisana nezidingo ezithile.Izinto zokwakha, idizayini yesitaki, isilawuli sokuvimba, amasu okumisa phansi, ukuvikela i-RF, ukwakheka kwengxenye nezinqubo zokuhlola konke kudlala indima ebalulekile ekuqinisekiseni ukusebenza kahle.Ubungcweti buka-Capel ekukhiqizeni i-PCB prototype yezinhlelo zokusebenza zemvamisa ephezulu busenza sibe uzakwethu ofanelekayo wezinkampani ezisembonini yezicelo zefrikhwensi ephezulu. Sithembe ukuthi sizoletha ama-prototypes e-PCB asheshayo, athembekile ahlangabezana nezidingo zakho ezithile futhi adlule okulindele.
