4.1 Izinto Ezigcwele Uma Ziqhathaniswa Nezingagcwalisiwe

Ukutholakala kwezinto ezibonakalayo kunquma ukuthi ukwenziwa kuqala ngosuku okukhishwa ngalo i-oda noma ngemva kwezinsuku ezi-5-15:

4.2 Ukuthunyelwa Kwezinto Zokusebenza Ukuze Kuqedwe Isikhathi Sokukhokha

Kuzinhlelo ze-HDI ezinama-oda aphindaphindayo kanye nezidingo zezinto ezikhethekile, izinto ezithunyelwa ngamakhasimende ziyisu eliphumelela kakhulu lokunciphisa isikhathi sokukhokha esitholakalayo. Ikhasimende lithenga futhi lithumele izinto efektri kusenesikhathi. Ifektri iyigcina ngokumelene nama-oda esikhathi esizayo. Umthelela wesikhathi sokukhokha wezinto: zero. Inzuzo eyengeziwe: izindleko zezinto zingase zibe phansi ngokuthenga ivolumu eqondile kune-markup yasefektri ekuthengweni.

Ukuthunyelwa kudinga: isivumelwano ngomthwalo wemfanelo wokugcina kanye nomshuwalense, inani elincane lezinto ezibekwe ngonyaka (ngokuvamile amaphaneli ayi-10-20 ngonyaka ukuze kuqinisekiswe izindleko zokuphatha), kanye nenqubo ecacile yokulandelela izinto (izinombolo zezindawo ezilandelwayo ngokusebenza kokukhiqiza ukuze kuphindwe ukuvinjelwa okulawulwayo).

4.3 Izinqubo Zokufaka Izinto Ezintsha

Uma izinto ezishiwo zingatholakali futhi isikhathi sokuhola sibalulekile, ukushintsha izinto ezifanelekile kungaqeda ukubambezeleka kokuthengwa. Ithimba lobunjiniyela lefektri kufanele liphakamise ukushintshana ngemibhalo yokulingana kagesi. Ukushintshana okuvamile okuvunyelwe:

• I-Megtron 6 → Isola I-Tera MT40 (i-Df efanayo ku-10 GHz, i-Dk ehlukile — idinga ukubalwa kabusha kwe-impedance)
• i-laminate ekhethekile ephansi yokulahlekelwa → i-Taconic RF-35 (vala izakhiwo zikagesi, qinisekisa ukuthi i-Dk ifanelana nemvamisa yakho)
• Ukufakwa esikhundleni komkhiqizo we-High-Tg FR-4 (Shengyi S1000-2M, Panasonic R-1566W, Isola 370HR — konke kuyafana nezinhlelo zokusebenza eziningi)

Njalo qinisekisa ukuthi okushintshiwe kuyahlangabezana nezidingo zemvamisa, ukulahlekelwa, kanye ne-Tg yomklamo wakho ngaphambi kokugunyaza. Ukushintshana ngaphandle kokuqinisekiswa kuwumthombo ovamile wokwehluleka kwensimu kumiklamo ezwela ubuqotho besignali.

5) Izinqumo Zokuklama Ezinciphisa Isikhathi Sokuhola Ngaphandle Kokusheshisa

5.1 Ukunciphisa Uhlobo lwe-HDI

Ukunciphisa isikhathi sokuhola okunomthelela omkhulu: ukuqinisekisa ukuthi umklamo wakho udinga ngempela Uhlobo III ngaphambi kokuwucacisa. Ibhodi yohlobo III ithatha izinsuku ezingu-18-25; ibhodi yohlobo II ithatha izinsuku ezingu-14-18; ibhodi yohlobo I ithatha izinsuku ezingu-10-14. Ukonga isikhathi sokuhola kusukela ekuncishisweni kohlobo III→Uhlobo II→Uhlobo I kuyizinsuku zebhizinisi ezingu-4-11 ngesinyathelo ngasinye.

Umbuzo okufanele uwuphendule: ingabe i-fanout yakho ye-BGA idinga ama-via afihliwe kuma-core angaphakathi (Uhlobo III), noma ingabe ingafinyelelwa ngama-via angaphandle angaboni kahle anezinga ezimbili (Uhlobo II), noma ngama-via angaphandle angaboni kahle anezinga elilodwa (Uhlobo I)? Lo mbuzo uphendulwa kangcono ngesikhathi sokubuyekezwa kwe-DFM, hhayi ngemva kokuzibophezela ekuqoqweni. (bheka uhlu lokuhlola lwe-DFM lwamabhodi e-HDI ) Umklamo we-PCB we-Highleap kanye nensizakalo ye-DFM ihlola ukungenzeka kokunciphisa uhlobo lwe-HDI kumadizayini athunyelwe.

5.2 Okubekwe Ku-Staggered-to-Staggered Ngokuguqulwa

Ama-microvia ahlanganisiwe adinga ngokugcwalisa (ukujova kwe-resin ku-via barrel) kanye nokuhlelwa (ukulinganisa ubuso ngomshini noma ngamakhemikhali) phakathi kwemijikelezo yokwakheka. Lokhu kucubungula phakathi kwemijikelezo kunezela amahora angu-8-16 ngesendlalelo ngasinye esihlanganisiwe. Ukuguqula kube ama-microvia ahlanganisiwe (okungenani okungenani u-0.25mm phakathi kokuguqulwa kwesendlalelo) kuqeda ukugcwalisa kanye nokuhlelwa ngokuphelele, konga izinsuku zebhizinisi eziyi-1-2 ngomjikelezo ngamunye wokwakheka.

Izindleko zendawo yokuqondisa ziyamangaza: indawo eyengeziwe engu-5–8% endaweni ye-fanout ye-BGA. Kumabhodi anendawo yokuqondisa etholakalayo ekhoneni le-BGA, lokhu kushintshana cishe kufanelekile kuwo wonke umuntu kokubili ngesikhathi sokuhola kanye nezinzuzo zezindleko.

5.3 Ukuphelela Kwefayela kanye Nesimo se-DFM

7.1 I-Standard Lead Times Highleap izibophezele ku

7.2 Uhlelo Lokugcina Izinto Ezibalulekile

I-Highleap ine-FR-4 ejwayelekile, i-FR-4 ene-Tg ephezulu, kanye ne-FR-4 engena-halogen kuzo zonke izinhlobo zobukhulu obujwayelekile njengejwayelekile. Kumakhasimende anevolumu asebenzisa i-Megtron 6, i-I-Tera MT40, noma imindeni ekhethekile ye-laminate elahlekelwa kancane, izinhlelo zokuthumela izinto ezinikezelwe ziyatholakala. Izinto ezithunyelwe ziqeda isikhathi sokuthola izinto ngokuphelele futhi zinikeza ukuhambisana kwe-lot-to-lot Dk ezinhlelweni lapho ukuphindaphindwa kwe-impedance kudinga khona.

7.3 Ukuzibophezela Ekulethweni Kwempahla Ngesikhathi

I-Highleap izibophezela ekulethweni ngesikhathi kanye nesiqinisekiso sokufaka esikhundleni: uma ukukhiqiza kuthunyelwa ezinsukwini ezingaphezu kwezi-2 zebhizinisi ngemuva kosuku olubekiwe, amabhodi okufaka esikhundleni anikezwa mahhala endaweni elandelayo yokukhiqiza etholakalayo. Lesi siqinisekiso sisebenza kuma-oda ajwayelekile nasheshayo. Idatha yokusebenza ngesikhathi yezinhlelo ze-HDI iyatholakala uma iceliwe.

7.4 Ukubuyekezwa kwe-DFM kanye nokuhlolwa kokulungela amafayela

I-oda ngalinye elisha le-Highleap HDI lithola isibuyekezo samahhala se-DFM zingakapheli amahora angama-24 kusukela kuthunyelwe ifayela (amahora angama-48 ohlobo lwesithathu oluyinkimbinkimbi). Isibuyekezo sikhomba zonke izinkinga ezingadala imibuzo yobunjiniyela kanye nokugcinwa kwemisebenzi ngaphambi kokuba i-oda libekwe emgqeni wokukhiqiza. Imisebenzi ethunyelwe ngamafayela aphelele, ahlanzekile e-DFM ngokuvamile iqala ukuncishiswa zingakapheli amahora ama-4 kusukela kuqinisekiswe i-oda — okwandisa ukusetshenziswa kwesikhathi sokuhola esizibophezele.
