Amakhono okukhiqiza e-PCB athuthukisiwe, agxile ezintweni ezinembile kakhulu, ezinzima kakhulu, nezikhethekile, akhonza izimboni ezifana nocwaningo lwesayensi, i-RF, ezempi, ezokwelapha, amarobhothi, kanye ne-AI.
Uhlobo lwe-PCB
Umbono Womlando: Ukuvela "Ezinyangeni" Kuya "Ezinsukwini"
Uma sibheka emuva emlandweni wemboni ye-elekthronikhi, ukukhiqizwa kwe-PCB kwake kwaba yisithiyo eside nesibuhlungu.
- ▶ Isikhathi Sezincwadi Ezibhalwe Ngesandla (Phakathi Nekhulu Lama-20):Ezinsukwini zokuqala, amasekethe akhiwa kusetshenziswa izintambo "eziqondile", ezazinkulu futhi zingathembekile. Ukufika kwama-PCB kwakuyisinyathelo esikhulu sokuqhubekela phambili, kodwa inqubo yayithembele ngokuphelele ekudwetshweni ngesandla, ukuvezwa kwefilimu, kanye nokuqoshwa kwamakhemikhali. Umjikelezo wokuphindaphinda ungathatha amasonto noma ngisho nezinyanga.
- ▶ Ukumiswa kanye neNkathi ye-CAM (Ekupheleni kwekhulu lama-20):Ngokuthuthuka kobuchwepheshe bokukhiqiza obusizwa yikhompyutha (i-CAM), ifomethi ye-Gerber yaba yindinganiso, okwenza kube nokuhlukaniswa kokuqala kwedijithali kokuklama nokukhiqiza. Kodwa-ke, inqubo yayisadinga ifilimu ebonakalayo namathuluzi (isb., ukubhoboza izinhlelo ze-NC), okuhlala kunzima.
- ▶ I-Rapid Prototyping Revolution (Ekuqaleni kwekhulu lama-21 - Okwamanje):I-inthanethi, i-Laser Direct Imaging (LDI), ukubhola ngokunemba okuzenzakalelayo, kanye nezinto ezijwayelekile kwaveza izinsizakalo ezikhethekile ze-PCB ezisheshayo. Ngoku-oda ku-inthanethi, imigqa yokukhiqiza ezenzakalelayo, kanye namanethiwekhi okuhambisa asebenzayo, bacindezele izikhathi zokuhola ze-PCB kusukela "emasontweni" kuya "ezinsukwini," okushintsha ngokuphelele umdlalo.

※ Isifundo Somlando:Intuthuko ngayinye yezobuchwepheshe icindezele isikhathi kusukela "embonweni" kuya "entweni ebonakalayo." Lokhu kwanda kwesivinini kuguqule ukuthuthukiswa komkhiqizo kusuka "ekugembeni" okulandelanayo, okubiza kakhulu kwaba inqubo efanayo, engabizi kakhulu "yokuphindaphinda okusheshayo nokwehluleka."
Ukuhlolwa Okusheshayo Nokuqinisekiswa Komkhiqizo: I-Flywheel Yokuqaliswa Kwemakethe Okusheshisiwe
Ukubaluleka kwe-prototyping esheshayo akusikho nje kuphela esivinini sayo, kodwa nangendlela enika amandla ngayo yonke inqubo yokuqinisekisa.
① Ukuqinisekiswa Kokusebenza: Lesi yisinyathelo esiyinhloko. Ngemva kokuhlanganisa ibhodi, onjiniyela benza izivivinyo zokuvula amandla kanye nokulungisa amaphutha okuyisisekelo ukuqinisekisa ukuthi umklamo wesekethe ulungile. Ukubhala ngephrothoyiphu okusheshayo kuvumela amaqembu okuklama ukuthola nokulungisa amaphutha okukhetha i-schematic noma izingxenye zingakapheli izinsuku.
② Ukuqinisekiswa Kokusebenza: Ezinhlelweni zokusebenza ezivame kakhulu, ezisheshayo, noma ezinamandla aphezulu, ukwakheka kwe-PCB kubalulekile ekuboniseni ubuqotho, ubuqotho bamandla, kanye nokuhambisana kwe-Electromagnetic (EMC). Ama-prototype avumela ukuhlolwa kwasekuqaleni kwelebhu ukuhlola ukuthi ngabe izilinganiso zokusebenza eziqinile ziyahlangatshezwana yini.
③ Ukuqinisekiswa kwe-DFM/DFA: Lona uHlelo Lokuklama Ukuqinisekiswa Kokwenziwa/Ukuhlanganiswa. Ibhodi elingokoqobo livumela onjiniyela ukuthi bahlole ukubekwa kwezingxenye, isikhala, ukuphathwa kokushisa, kanye nokufaneleka kokuhlanganiswa okuzenzakalelayo. Ukuhlonza izinkinga ze-DFM/DFA kusenesikhathi kuvimbela ukulahlekelwa okukhulu ngesikhathi sokukhiqizwa ngobuningi.
④ Ukuqinisekiswa Kwezinto Ezisetshenziswa Ngomshini Nokwakheka Kwefomu: Ama-prototype asiza ukuqinisekisa ukuthi ubukhulu be-PCB, ukuma, kanye nezikhundla zesixhumi zihambisana kahle nendawo ebiyelwe yomkhiqizo, okunikeza idatha enembile yomklamo wemishini.
※ I-Logic of Speed: Ukuphindaphinda ngakunye okusheshayo "komklamo-isibonelo-ukuqinisekisa" kususa iphuzu elingase libe yingozi. Uma umjikelezo wokuphindaphinda umfushane, kulapho imijikelezo eminingi yokuqinisekisa ingaqedwa ngesikhathi esithile, kusheshiswe ukuvuthwa komkhiqizo futhi kuqinisekiswe ukushintshela okubushelelezi ekukhiqizweni okukhulu kanye nokwethulwa kwemakethe kwekhwalithi ephezulu.
Intuthuko Yezobuchwepheshe: Isisekelo Sokukhiqiza Okusheshayo
Ukwenziwa kweprototype okusheshayo kwesimanje kuvunyelwe ubuchwepheshe obuningana obubalulekile:
-
Ukuthwebula Izithombe Okuqondile Nge-Laser (LDI)
Ithatha indawo yefilimu ebonakalayo ngokusebenzisa i-laser ukuze ifanekise ngqo i-photoresist, inikeza ukunemba okuphezulu, isivinini, kanye nokuzivumelanisa nezimo ukuze kukhiqizwe ama-batch amancane, axutshwe kakhulu.
-
Ukuzenzakalela kanye Nokugeleza Komsebenzi Kwedijithali
Kusukela ekuhlolweni kwe-Automated Optical (AOI) kuya ekuhlolweni kwe-flying probe kanye nokuphathwa kwezinto okuzenzakalelayo, lezi zinqubo zinciphisa ukungenelela ngesandla, zandisa ukusebenza kahle kanye nokuvumelana.
-
Izinto Zokusebenza Okuphezulu
Uhla olubanzi lwezinto zokwakha, kusukela ku-FR-4 ejwayelekile kuya ku-high-frequency/low-loss (isb., Rogers), i-high-Tg, kanye ne-flexible substrates (PI), zihlangabezana nezidingo ezisheshayo zezinhlelo zokusebenza ezahlukahlukene.
-
Amapulatifomu Okubambisana Ku-inthanethi
Amakhasimende athumela amafayela e-Gerber ku-inthanethi, futhi uhlelo lwenza ngokuzenzakalelayo ukuhlaziywa kwe-DFM futhi lunikeze izingcaphuno ezisheshayo, okwenza inqubo yoku-oda ibe lula.
Izinhlobo Ezivamile ze-PCB kanye Nezidingo Zepharamitha Yenqubo Eyinhloko
Ukwenziwa kweprototype okusheshayo kwesimanje kuvunyelwe ubuchwepheshe obuningana obubalulekile:
| Ohlangothini Olulodwa | Izindleko eziphansi kakhulu, isakhiwo esilula. Sisetshenziswa kuma-electronics asebenzisa amandla amancane. | Ubukhulu bebhodi: 1.0mm, 1.6mm |
| Izinhlangothi Ezimbili | Uhlobo oluvame kakhulu, oluqondisa izinhlangothi zombili. Lusetshenziswa emikhiqizweni eminingi ejwayelekile ye-elekthronikhi. | Ubukhulu bebhodi: 1.0mm, 1.6mm |
| Izendlalelo Eziningi | Ukuminyana okuphezulu, ukusebenza okuphezulu. Kusetshenziswa kumasekethe ayinkimbinkimbi njengama-smartphone, izilawuli zezimboni, kanye nemishini yokuxhumana. | Izendlalelo: 4-12 (ezivamile) |
| Imvamisa Ephakeme/Isivinini Esiphezulu | Ukulahlekelwa okuphansi, i-Dk/Df ezinzile. Isetshenziswa ku-5G, radar, ukuxhumana kwesathelayithi. | Izinto zokwakha: iRogers, iTaconic, njll. |
| I-HDI | I-High-Density Interconnect, isebenzisa ama-micro-via. Kumadivayisi aphathekayo angenasikhala esiningi. | Ukulandelela/Isikhala Esincane: ≤0.075mm |
| Ukugoba/Ukugoba Okuqinile | Iyagobeka, i-3D assembly. Isetshenziswa kumakhamera, kumadivayisi ezokwelapha, nasezintweni ezigqokwayo. | I-Substrate: I-Polyimide (PI) |
Isiphetho
Ukwenziwa kwe-prototype okusheshayo kwe-PCB kuguquke kusuka enkonzweni esekelayo kwaba yinsika yesu lokusungula izinto ezintsha ze-elekthronikhi zanamuhla. Kuhlanganisa ngokujulile ifilosofi yesimanje ye-R&D yokuthi "isikhathi siyimakethe, futhi ukuqinisekiswa kuyinani." Ngokuqonda ukubaluleka kwayo okubalulekile, ukufunda ezindleleni zomlando kanye nentuthuko yezobuchwepheshe, kanye nokuqonda izidingo zenqubo zezinhlobo ezahlukene ze-PCB, izinkampani zingakha iluphu esebenza kahle nethembekile "yokuklama-ukuqinisekisa-ukulandelela". Lokhu kuzenza zikwazi ukuthatha isinyathelo emakethe encintisana kakhulu futhi ekugcineni ziwine umncintiswano wokuletha imikhiqizo ephumelelayo emakethe.
