Izigaba Zesevisi Ezihlanganisiwe
Isigaba 1: Ukubuyekezwa kwe-DFM kwezinhlelo ze-370HR
Ukubuyekezwa kwe-370HR DFM kubhekana nemikhawulo yokuklama ethile yezinto ezibonakalayo ezingambozwa yi-FR-4 DFM ejwayelekile. Izinto ezine okumele zibuyekezwe ngaphambi kokuba kuqale ukwenziwa:
Ukulungiswa kwesitayela se-Prepreg vs. impedance model: Imodeli yakho ye-impedance field solver isebenzisa ubukhulu obuthile be-dielectric. Lobo bukhulu bunqunywa isitayela se-prepreg — 1080, 2116, noma 7628 — kanye nephesenti lokuqukethwe kwe-resin. Ukungafani phakathi kwe-prepreg emodeliwe kanye ne-prepreg eyenziwe yimbangela evame kakhulu ye-prototype-to-production impedance drift. Ukubuyekezwa kwe-DFM kuqinisekisa ukuthi isitayela se-prepreg esicacisiwe sifinyelela ubukhulu be-dielectric obuqondiwe futhi sivala leso sitayela kulo lonke uhlelo. Funda kabanzi mayelana nokuthi ukukhetha kwe-prepreg kuthinta kanjani impedance kumhlahlandlela wethu wokwakha i-PCB laminate.
Ukuqinisekiswa kwesilinganiso se-aspect: Ama-via anesilinganiso se-high-aspect-ratio (>8:1 we-IPC Class 2, >10:1 we-Class 3) kunzima ukuwafaka ngokulinganayo — ithusi eliphakathi nendawo yebharele le-via lithola i-plating encane kunobuso. Ekwakhekeni kwe-370HR high-layer-count, i-via plating ukufana kuyisici esiyinhloko sokuthembeka ngoba ngisho ne-370HR's Z-axis CTE ephansi ayikwazi ukuvimbela ukuqhekeka ngethusi elinganele. I-DFM ikhomba ukwephulwa kwesilinganiso se-aspect futhi incoma ukulungiswa kosayizi wokubhoboza noma ukujiya kwebhodi ngaphambi kokusebenzisa amathuluzi.
