6. Izindleko Ezifihliwe Ezifutha Ubumpumputhe Ngezilinganiso ze-PCB

6.1 Ukwabiwa Kokulahlekelwa Kwesivuno

Amabhodi angaboni nge-HDI anesivuno esiphansi sokudlula kokuqala kune-PCB ejwayelekile. Izindlela ezintathu eziyinhloko zokuhluleka ziyi-blind via opens (ukucwebezela kwethusi okungaphelele emgqonyeni, okwenzeka ku-2-5% wama-vias ekuqhutshweni kokuqala kokukhiqiza futhi kungaphansi kuka-1% uma ikhono lenqubo selisunguliwe), amaphutha okubhalisa (angaboni nge-drilled kancane ngaphandle kwephedi ngenxa yokungahambisani kahle kwesendlalelo, okuthinta u-1-3% wamabhodi ngesikhathi sokusetha kokuqala), kanye nokuhlukanisa ezindaweni zokwakheka kwesendlalelo (ngaphansi kuka-1% kumiklamo eminingi kodwa kuyanda ngokubalwa komjikelezo we-lamination kanye nobukhulu bebhodi).

Abakhiqizi babiza ukulahlekelwa kwenzuzo ngamanani ngokwakha amabhodi angaphezu kuka-3-8% kunalawo a-odiwe, kanti okweqile kumboza izingcezu ezilindelekile. Lokhu kunezela u-3-8% ezindlekweni ezisebenzayo zamayunithi kumadizayini amasha. Kuma-oda aphindaphindwayo lapho kusungulwa khona ikhono lenqubo (i-Cpk), ukwabiwa kwenzuzo kwehla ngaphansi kuka-2%. Buza ukuthi ukulahlekelwa kwenzuzo kufakwe yini kuma-quotes esihlokweni sokuqala nokuthi intengo iyashintsha yini kuma-oda aphindaphindwayo njengoba inqubo yomkhiqizi ivuthwa kudizayini yakho ethile.

6.2 Izindleko Zokuhlola Ngokwezinga Lokuhlola

Kuphaneli yesibonelo yamabhodi ayi-10, ukuhlolwa kweKlasi 3 — i-X-ray engu-100%, ukuhlolwa kukagesi, kanye nekhuphoni ye-impedance — kunezela u-$16–$35 ngephaneli, noma u-$1.60–$3.50 ngebhodi. Kumabhodi ayi-100 kumaphaneli ayi-10, izindleko zokuhlola zifinyelela ku-$160–$350. Uma uqhathanisa izingcaphuno, qinisekisa ukuthi ububanzi bokuhlola buchazwe ngendlela efanayo kubo bonke abahlinzeki. Intengo yeyunithi ephansi engafaki ukuhlolwa kwe-X-ray kumklamo weKlasi 2 akuyona isilinganiso esifanayo.

6.3 Ukusheshisa Amaphrimiyamu

Isikhathi esijwayelekile sokuhola se-Hlobo I HDI izinsuku zebhizinisi eziyi-10-15; Uhlobo II ludinga izinsuku eziyi-15-20. Amanani okusheshisa asebenza kanje: ukujika kwezinsuku eziyi-7 kunezela u-25-40%; ukujika kwezinsuku ezi-5 kunezela u-40-60%; ukushesha okukhulu kwezinsuku ezi-3 koHlobo I kunezela u-80-120% kuphela. Uhlobo II noHlobo III zidinga imijikelezo eminingi ye-lamination futhi azikwazi ukufezwa ezinsukwini ezi-3 ezindaweni eziningi.

Ku-oda eliyisisekelo elingu-$3,000, ijubane lezinsuku ezi-5 lengeza u-$1,200–$1,800. Ukuqinisekisa amashejuli okukhiqiza amasonto ama-4-6 kusengaphambili kususa le zindleko ngokuphelele zokukhiqiza okuphindaphindayo.

6.4 Izindleko Ezingeziwe Ze-Laminate Ekhethekile

I-FR4 ejwayelekile inentengo yezimpahla futhi yakha isisekelo. Amaphrimiyamu e-laminate akhethekile ngaphezu kwe-FR4 ejwayelekile: I-High-Tg FR4 (Tg ≥170°C) ingeza u-15–30%; i-FR4 engena-halogen ingeza u-20–40%; ama-laminate aphakathi nokulahlekelwa njenge-Megtron 6 engeza u-200–400%; ama-laminate e-RF aphansi nokulahlekelwa njenge-laminate esezingeni eliphezulu engeza u-400–1,000%.

Kumabhodi e-HDI lapho ukusebenza kwesignali ye-RF noma isivinini esikhulu kudinga khona izinto ezilahlekelwa kancane kuphela ezingqimbeni zangaphandle zesignali, i-hybrid stackup — i-laminate ekhethekile elahlekelwa kancane noma i-Megtron 6 ku-L1 naku-L6, i-FR4 ejwayelekile ezingqimbeni zangaphakathi — inciphisa izinto ezibiza ngo-40-60% uma kuqhathaniswa nokwakhiwa kwe-premium egcwele i-laminate ngenkathi kulondolozwa ukusebenza kukagesi ezingqimbeni ezithwala izimpawu ezibalulekile.

Thola Isilinganiso Sakho Se-PCB Manje

7. I-Blind Via PCB kanye ne-Advanced PCB Manufacturing e-Highleap Electronics

I-Highleap Electronics yenza amabhodi angaboni ngama-HDI kusukela ku-Type I kuya ku-Type III, kufaka phakathi izakhiwo ze-microvia ezihlanganisiwe, ezigqitshwe ngokuhlanganiswa, kanye nama-stackups e-hybrid ane-laminate ekhethekile ephansi yokulahlekelwa noma izendlalelo zangaphandle ze-Megtron kuma-cores angaphakathi e-FR4. Amakhono adlula ngale kwamabhodi angaboni ngama-board aze afike kuhlu oluphelele lwezinhlobo ze-PCB ezithuthukisiwe — amabhodi ajwayelekile anezingqimba eziningi, i-rigid-flex, i-RF ephindaphindayo ephezulu, ithusi elisindayo, kanye ne-metal core — okuvumela amaqembu obunjiniyela ukuthi ahlanganise zonke izinhlobo zamabhodi ngaphakathi kwe-supply chain eyodwa.

Konke ukwenziwa okungaboni kahle kucashunwe ngokusobala okugcwele kwezinto zomugqa: indlela yokubhoboza kanye nokusetha, imijikelezo ye-lamination, ngokucaciswa kokugcwalisa, izinga lokuhlola, kanye ne-NRE kuhlukaniswe ngokwehlukana. Isilinganiso ngasinye sifaka isibuyekezo samahhala se-DFM esihlanganisa ukufaneleka kobubanzi bokubhoboza ngomshini uma kuqhathaniswa ne-laser, isidingo sokucaciswa kokugcwalisa, amathuba okuguqulwa okuhlanganisiwe, ukuhlaziywa kokunciphisa uhlobo lwe-HDI, kanye nokuhlolwa kokusetshenziswa kwephaneli - ngokuvamile kukhomba ukwehliswa kwezindleko okungu-10-30% ngaphandle kokushintsha kabusha umklamo. Amathuluzi agcinwa izinyanga ezingu-24, ngama-oda aphindaphindwayo ngaphakathi kwalelo windi anenani ngaphandle kwe-NRE.

Kumaphrojekthi adinga ukuhlanganiswa kwezinga lebhodi ngemva kokwenziwa, ukuhlanganiswa kwe-SMT PCB kuyatholakala ngaphakathi endlini ngokudluliselwa okungenamthungo kusuka emgqeni webhodi elingenalutho — kususa ingozi yokuthutha amabhodi e-HDI abucayi phakathi kwabathengisi bokwenziwa abahlukene kanye nabathengisi bokuhlanganiswa.
