Ngamavolumu angamayunithi angama-500, izindleko zokusetha zincishiswa cishe ku-$10 ibhodi ngalinye ngokuhlolwa okuphelele kwengeza u-$15 iyunithi ngayinye ngezindleko eziphelele cishe ku-$95, kwehle ku-$75 kumavolumu amayunithi angu-2,000 njengoba izindleko ezinqunyiwe ziqhubeka zihlakazeka futhi zibonisa indlela i-ceramic PCB ebiza ngayo i-premium kunezinye izindlela ze-FR-4 ezifakazelwa ukusebenza kahle okuphakeme.

I-LTCC Module: I-Advanced Technology Complexity

Imojula yesihlungi se-microwave ye-LTCC enezendlalelo ezihlangene eziyisishiyagalombili, izinqamuleli ezishumekiwe, nemigqa yokudlulisela ehlanganisiwe elinganisa u-20 x 30 mm idinga ukubhaliswa okunembayo kongqimba phakathi kwama-microns angu-±25, ngezindleko zempahla engu-$30 ibhodi ngalinye leteyiphu ye-LTCC nokunamathisela kwensimbi eyigugu naphezu kosayizi omncane. I-Lamination, ukudubula ngokuhlanganyela ku-850°C, kanye nokucubungula ngemva komlilo kwengeza u-$50 ngeyunithi ngayinye kuyilapho ukuhlola okuphelele kwe-RF kusetshenziswa abahlaziyi benethiwekhi ukuze kuqinisekiswe amapharamitha e-S kuwo wonke u-1-18 GHz kunikela omunye u-$25 ibhodi ngalinye, okuholela ezindlekweni zeyunithi ezingaphezu kuka-$100 ngisho naku-200-500 wamavolumu okubonisa ukucutshungulwa kobuchwepheshe be-LT.

Isiphetho: Ukulinganisa Ukusebenza Nezindleko

Ukuthuthukiswa kwezindleko ze-Ceramic PCB kudinga ukulinganisa izimfuneko zokusebenza ngokumelene namaqiniso ezomnotho ngokukhethwa kwezinto ezinolwazi, ukukhetha kwenqubo ye-metallization, kanye nokuhlelwa kwevolumu yokukhiqiza okumelela izindleko ezinkulu kakhulu ezitholakala emaqenjini aklama.

Ukuqonda lokhu kuhwebelana kusenesikhathi emijikelezweni yokuthuthukisa kunika amandla ukucaciswa okufeza ukusebenza okufanele okushisayo nokukagesi ngaphandle kokuthola amaphrimiyamu ngamakhono angadingekile, ngokucaciswa kahle kwe-ceramic PCB okungenzeka kumelele ukonga kwezindleko okungu-30-50% uma kuqhathaniswa nezinye izindlela ezishiwo kakhulu kuyilapho kugcinwa izidingo zokusebenza ezigcwele.

I-Highleap Electronics inikeza izinsizakalo zokubuyekezwa komklamo kanye nokubonisana kwe-DFM ukusiza amaqembu obunjiniyela ukuthi abhekane nalezi zindlela zokushintshana kwezindleko ngokusekelwe ezinkingeni zokukhiqiza zangempela, ahlole imininingwane ngokumelene namaqiniso okukhiqiza, athole amathuba okwenza ngcono, futhi anikeze ukubikezela kwezindleko okungokoqobo kuzo zonke izigaba ze-prototype kanye nokukhiqiza kwamaphrojekthi e-PCB e-ceramic.
