Impumputhe Enezingqimba Eziyi-8 Engcwatshwe Ngokuhlukaniswa Kwentengo Ye-PCB

I-blind yezingqimba ezingu-8 ezifihliwe ngentengo ye-PCB — amabanga entengo yesibonelo ahluka kakhulu ngokwe-stackup, usayizi webhodi, ubuningi, kanye nezimo zemakethe. Njengereferensi eqondile kuphela (hlala uthola ikhotheshini nge-Gerber yakho yangempela): Uhlobo I (1+6+1) lungaqala cishe ku-$45–$75/ibhodi, Uhlobo II (2+4+2) cishe ku-$72–$120/ibhodi, kanye noHlelo III olune-vias ezifihliwe cishe ku-$95–$165/ibhodi, ebhodini elijwayelekile elingu-100×100mm FR-4 ezingcezu ezingu-10–25 ngaphansi kwezimo ezijwayelekile. Lawa mabanga okubhekisela abonisa ibhodi elingu-100×100mm ku-FR-4 ejwayelekile, ukuqeda kwe-ENIG, i-IPC Class 2, ngamanani ezingcezu ezingu-10–25. Umehluko wamanani angu-2.0–2.4× phakathi kokucushwa kwezingcezu ezingu-8 okushibhile kakhulu nokubiza kakhulu uqhutshwa cishe ngokuphelele yinani lomjikelezo we-lamination — Uhlobo I ludinga imijikelezo emi-2 kuyilapho Uhlobo III ludinga u-4–5 — hhayi ngezindleko zezinto eziyisisekelo zokwengeza izendlalelo. Ukuqonda ukuthi yikuphi ukwakheka okudingayo ngempela (esikhundleni sokushintsha uhlobo lwesithathu ukuze uthole amandla aphezulu) kuyisinqumo sezindleko esinomthelela kakhulu sohlelo lwe-HDI olunezingqimba ezingu-8 (bheka umhlahlandlela wokuklama ukwakheka kwe-HDI stackup )

Thola Isilinganiso Sentengo Ye-HDI Yezingqimba Ezi-8

1) Impumputhe Enezingqimba Ezingu-8 Engcwatshwe Ngentengo ye-PCB Ngokucushwa Kwe-Stackup

1.1 Isifinyezo Sebanga Lentengo Ngohlobo

Isisekelo sereferensi kuphela (izingcaphuno zangempela zincike ku-Gerber yakho kanye nemininingwane): 100×100mm, i-standard high-Tg FR-4, i-ENIG, i-IPC Class 2, ama-300 blind vias ( staggered ), awekho ama-via-in-pad . Engeza u-20–35% we-stacked ngokusebenzisa izilungiselelo. Engeza u-15–25% wezinto ezisebenza kahle kakhulu (Megtron 6, I-Tera). Engeza u-10–18% we-IPC Class 3.

1.2 Yini Ebeka Phansi: Isakhiwo Sezindleko Zomjikelezo Wokumboza Ilamination

Intengo yanoma iyiphi i-blind enezingqimba ezingu-8 egqitshwe ngebhodi isethwe ngemijikelezo ye-lamination, hhayi ukubalwa kwezingqimba. Nansi intengo etholakala ngamanani e-prototype angu-50:

• Uhlobo I (imijikelezo emi-2): ~$18–$24 ngentengo yomjikelezo webhodi lokubopha
• Uhlobo II (imijikelezo emi-3): ~$30–$42 ngentengo yomjikelezo webhodi lokubopha
• Uhlobo III (imijikelezo engu-4–5): ~$45–$68 ngentengo yomjikelezo webhodi lokubopha

Intengo esele yebhodi — ukuthwebula izithombe, ukucwebezela, ukuqopha, ukuhlola, ukuqeda — icishe ilingane kuzo zonke izinhlobo zosayizi webhodi ofanayo. Umehluko wezindleko ze-lamination uchaza cishe yonke igebe lentengo phakathi kokucushwa.

1.3 Kungani Izendlalelo Eziyi-8 Zingabizi Ngama-33% Ngaphezu Kwezendlalelo Eziyi-6

Umbono ovamile oyiphutha ukuthi inani lezingqimba lilinganisa intengo ngokulandelana. Akunjalo. Ukuqhathanisa uhlobo olufanayo lwe-HDI ekubalweni kwezingqimba ezahlukene:

• I-HDI yohlobo I enezingqimba ezi-6 (ama-pcs angu-50, 100×100mm): cishe $38–$52/ibhodi (ububanzi bokubhekisela)
• I-HDI yohlobo I enezingqimba ezingu-8 (ama-pcs angu-50, 100×100mm): cishe $48–$62/ibhodi (ububanzi bokubhekisela) — kuphela ngo-20–26% owengeziwe naphezu kwezingqimba ezingu-33% owengeziwe

Isizathu: inani lomjikelezo we-lamination alishintshi (kusasele imijikelezo emi-2 yohlobo I kungakhathaliseki ukuthi inani lezingqimba liphelele), futhi izindleko zezinto ezisemaphethelweni zezingqimba ezimbili ezengeziwe zangaphakathi ziphansi uma kuqhathaniswa nezindleko zenqubo esezivele zikhona.

2) Indlela Ukukhetha Okuhlanganisiwe Okulawula Ngayo Intengo: Uhlobo I vs. Uhlobo II vs. Uhlobo III

2.1 Uhlobo I (1+6+1): Isikhathi Sokukhetha

I-1+6+1 stackup inama-blind vias kuphela kungqimba lwangaphandle lwe-buildup (L1–L2 kanye ne-L7–L8) angenawo ama-billed vias noma ama-stacked microvias enkabeni. Lena ukukhetha okufanele uma:

• Zonke izingxenye ze-BGA zinephimbo elingu-0.5mm noma ngaphezulu futhi zingavuthwa ngesendlalelo esisodwa sama-blind vias
• Ukuhambisa isignali phakathi kwezingqimba zangaphakathi kungasebenzisa ama-via angena ngembobo (atholakala ezingqimbeni eziyisi-6 eziyinhloko)
• Ubuningi bebhodi abuphezulu kakhulu njengoba kudinga ungqimba lwangaphakathi ngokushintshashintsha

Uhlobo I lufinyelela izinga eliphansi kakhulu le-blind elimbozwe ngentengo ye-PCB ngoba imijikelezo emibili ye-lamination iwubuncane banoma yikuphi ukwakhiwa kwe-HDI. Ukuthuthela ku-Type II kunezela umjikelezo ongu-1 kanye no-$20–$35/ibhodi ngamanani e-prototype ukuze kusebenze umzila ongasetshenziswa yimiklamo eminingi.

2.2 Uhlobo II (2+4+2): Isinyathelo Sokwanda Kobuningi

Isakhiwo esingu-2+4+2 sengeza ungqimba lwesibili lokwakheka ohlangothini ngalunye (ukufakwa kwe-L1–L2–L3 phezulu, i-L6–L7–L8 phansi). Lokhu kwenza:

• Kuhle kakhulu ngokufaka i-stacking yezingxenye ze-BGA ze-pitch ezingu-0.40mm ezinenani eliphezulu le-I/O
• I-blind enezingqimba ezimbili ngokushintsha esikhundleni seyodwa, ikhulula izingqimba eziningi zangaphakathi zomzila wesignali
• Umthamo wocingo ophezulu endaweni ngayinye yeyunithi kunohlobo I

Intengo ephezulu yohlobo lwesibili ngaphezu kohlobo lwe-I: cishe u-40–55% ngamanani e-prototype, ancipha abe ngu-32–42% ngamanani okukhiqiza njengoba izindleko zokusetha zincipha. Cacisa uhlobo lwesibili kuphela uma i-fanout yakho ye-BGA noma ubuningi be-routing buyidinga — hhayi njengokuzenzakalelayo "kwekhono elingcono."

2.3 Uhlobo III: Ama-Vias Angcwatshwe Emkhathini

Uhlobo lwesithathu lunezela ama-via afihliwe enkabeni yangaphakathi (isb., phakathi kwe-L3–L4, L4–L5, noma i-L5–L6). Lawa ma-via afihliwe avumela ukuxhumana kwengqimba yangaphakathi ngaphandle kokusebenzisa imbobo ngokusebenzisa isikhala, okwandisa umzila otholakalayo kuzo zonke izingqimba. Umthelela wezindleko ubalulekile:

• Ipheya ngalinye elingcwatshwe ngesendlalelo lenezela imijikelezo engu-1-2 ye-lamination ekwakheni okuyinhloko
• Ukugcwatshwa ngokucubungula (ukubhoboza ngomshini, ukucwebezela, ukuhlolwa phakathi kwemijikelezo) kunezela u-$35–$65 ebhodini ngobuningi beprototype
• Isamba seprimiyamu yohlobo lwesithathu ngaphezu kohlobo I: 100–135% kumodeli, 90–120% ekukhiqizweni

Uhlobo lwesithathu lufanelekile ngobuningi bomzila obulingana nezingqimba ezingu-12-20 obucindezelwe zibe yizingqimba ezingu-8, noma ngemiklamo yedijithali esheshayo edinga ukuguqulwa kwezingqimba ngaphandle kwezingcezu ezingqimbeni zangaphakathi zesignali.

2.4 Umthelela Wentengo Ehambisanayo vs. Engalingani

Ama-stackup angalingani — lapho ama-via angcwatshwe ebekwa ohlangothini olulodwa kuphela lwe-core (isb., L3–L5 kodwa hhayi isibuko L4–L6) — andisa ingozi ye-warpage futhi adinga ukulungiswa okwengeziwe kwephrofayili yabezindaba. I-Cost adder: 8–15% ngaphezu kwe-symmetric equivalents. Njalo klama i-symmetric ngokubekwa e-core ngaphandle kokuthi ukwakheka kwesignali kwenza i-asymmetry igwemeke. Imiklamo engalingani ene-asymmetry engaphezu kweyodwa engcwatshwe ingaba namazinga okulahlwa angu-3–5× aphezulu kunemiklamo e-symmetric kwezinye izimboni.

3) Nge-Count and Architecture: Izindleko Ezilawulwa Kakhulu Eziguquguqukayo

3.1 Umthelela Wokubala Ngenani Le-HDI Eliphelele Elinezingqimba Eziyi-8

3.2 I-Stacked vs. Staggered: Isinqumo Sokuklama Esinomthelela Omkhulu

Ukuze uthole ibhodi lohlobo I elinezingqimba ezingu-8 elinama-vias angu-600 angaboni:

Ukucushwa okuhlanganisiwe:

• Ngokubhoboza: ~$10.80/ibhodi (okufanekisayo)
• Ukugcwaliswa kwe-resin (ama-via angu-600 × ~$0.09): ~$54.00/ibhodi (okufanekisayo)
• Ukuhlela: ~$3.20/ibhodi (okufanekisayo)
• Isamba ngezindleko: $68/ibhodi

Ukucushwa okuxakile:

• Ngokubhoboza: ~$10.80/ibhodi (okufanekisayo)
• Ukugcwaliswa kanye nokuhlelwa kabusha: $0
• Isamba ngezindleko: $10.80/ibhodi

Ukonga okubonakalayo: ~$57.20/ibhodi — okumabhodi ayi-100 amele cishe u-$5,720 ekuncishisweni kwezindleko kusukela kulolu shintsho lomklamo (ukubalwa kwereferensi kuphela). Inhlawulo yendawo yomzila yokuma ingama-5–8% endaweni ye-BGA fanout. Lokhu kuthengiselana cishe kuyazuzisa yonke indawo.

3.3 Isu Lokusebenzisa Imigodi Engena Emigodini ku-HDI Enezingqimba Ezingu-8

Akuwona wonke ama-via kumklamo we-HDI onezingqimba ezingu-8 okudingeka abe yi-blind noma i-blinded via. Ama-via e-through-hole axhumanisa zonke izingqimba ezingu-8 ahlala esebenza ekusabalalisweni kwamandla, ukuqondisa iwashi, nanoma yisiphi isignali esingadingi ukufakwa kwe-BGA eqondile. Ama-via e-through-hole abiza u-$0.002–$0.006 ngalinye — ashibhile ngo-3–5× kune-via e-blind ebholwe nge-laser. Ukubhuka ama-via e-blind ukuze kutholakale i-BGA kanye ne-high-speed signal escape lapho kudingeka khona, nokusebenzisa ama-via e-through-hole yonke indawo, kunciphisa intengo ye-blind enezingqimba ezingu-8 embozwe nge-PCB ngaphandle kokubeka engcupheni ubuqotho besignali.

4) Ama-Curves Amanani Evolumu e-HDI Enezingqimba Ezingu-8

4.1 Ukuthuthuka Kwentengo Ngokwenani

Qaphela: Zonke izintengo ezingezansi ziyizinkomba ezibonisa amabhodi ajwayelekile angu-100×100mm FR-4 ngaphansi kwezimo ezijwayelekile zemakethe. Isilinganiso sakho sangempela sizohluka ngokusekelwe kubukhulu bebhodi, imininingwane, kanye nezindleko zezinto zamanje. Thumela i-Gerber yakho ukuze uthole amanani anembile.

Ukwehla okukhulu kwentengo kwenzeka phakathi kwe-prototype (ama-pc ayi-10) kanye nokukhiqizwa okuphansi (ama-pc angama-50–100) njengoba i-NRE kanye nezindleko zokusetha zincipha. Isinyathelo esilandelayo sokwehla senzeka kuma-pc angaphezu kwama-500 lapho kusebenza khona ukulungiswa kokusetshenziswa kwamaphaneli kanye nomnotho wokucubungula ama-batch.

4.2 Ukwehliswa Kwemali Kwe-NRE Kuwo Wonke Ama-oda Anezingqimba Eziyi-8

Uhlobo I HDI NRE: $480–$820. Kumabhodi ayi-10: kwengeza u-$48–$82/ibhodi. Kumabhodi ayi-500: kwengeza u-$0.96–$1.64/ibhodi. Lo mkhawulo wokunciphisa imali wenza umnotho wentengo yeprototype ubukeke mubi kakhulu kunentengo yokukhiqiza — kodwa izindleko zebhodi ngalinye ngevolumu yizo ezinquma ukuncintisana komkhiqizo. Hlola i-blind-layer engu-8 efihliwe ngentengo ye-PCB ngenani lokukhiqiza olilindele, hhayi ngenani leprototype.

4.3 Ivolumu Yokulinganisa Isilinganiso Sokuhlola Ukuqina

Ukuhlolwa kwe-Flying Probe (akukho okufakiwe): cishe u-$3.50–$7.00/ibhodi, yize izimali zokuhlola zangempela ziyahlukahluka kuye ngemboni. Ukuhlolwa kwe-Fixture: ngokuvamile u-$550–$900 izindleko ze-fixture yesikhathi esisodwa (ireferensi), bese kuba u-$0.60–$1.20/ibhodi. Ukulinganisa: cishe amabhodi angu-150–200 nge-oda ngalinye. Kuzinhlelo ze-HDI ezinezingqimba ezingu-8 ezinama-oda ekota angaphezu kwamabhodi angu-200, ukuhlolwa kwe-fixture kunganciphisa izindleko zokuhlola ngebhodi ngalinye cishe u-$2–$5/ibhodi - okufanele ukutshalwa kwezimali kwe-fixture ngemuva kwe-oda lesibili.

5) I-NRE kanye ne-Tooling yamabhodi ambozwe izimpumputhe anezingqimba ezingu-8

5.2 Umthelela Wenqubomgomo Yokugcina Amathuluzi

Kuzinhlelo ze-HDI eziphindaphindayo ezinezingqimba ezingu-8 ezinama-oda ekota, ukugcinwa kwamathuluzi kufana nokonga i-NRE ephelele njalo ngekota ngemva kweyokuqala. Kumklamo wohlobo I one-$700 NRE kanye nama-oda angu-4/ngonyaka: ukugcinwa kwamathuluzi konga u-$2,100/ngonyaka. Kumabhodi angu-100/oda, lokho kungu-$5.25/ibhodi/ngonyaka ekongeni izindleko ezifihliwe ngokusebenzisa ifektri enokugcinwa kweminyaka eminingi uma kuqhathaniswa neyokuhlanza ukugcinwa kwamathuluzi ngemva kwezinyanga ezingu-12.

6) Izinga le-HDI elinezingqimba ezingu-8 vs. Izinga le-10 elinezingqimba: Ukuhlaziywa kwe-Break-Even

6.1 Uma i-10-Layer Standard idlula i-8-Layer HDI entengo

I-PCB ejwayelekile enezingqimba eziyi-10 ingacashunwa kusukela ku-$32–$52/ibhodi ngezingcezu ezingama-50 ngaphansi kwezimo ezijwayelekile (100×100mm, FR-4, ENIG) — amanani angempela ayahlukahluka. I-HDI yohlobo lwe-I enezingqimba eziyi-8 ingacashunwa cishe ku-$48–$62/ibhodi ngenani elifanayo ngaphansi kwezimo ezijwayelekile. Izinga lezingqimba eziyi-10 lishibhile uma:

• Zonke izingxenye zine-pitch engu-≥0.5mm (ayikho i-BGA edinga ama-vias abhobozwe nge-laser ukuze kufakwe i-feni)
• Imikhawulo yobukhulu bebhodi ivumela izendlalelo ezengeziwe zangaphakathi ukuthi zithwale umzila obekungaphathwa yi-HDI blind vias ngenye indlela.
• Umkhiqizo awudingi ukuncishiswa kwendawo yebhodi okwenziwa yi-HDI

Kulezi zimo, i-PCB ejwayelekile enezingqimba eziyi-10 iyincazelo efanele. Ukucacisa i-HDI enezingqimba eziyi-8 yomklamo ongase uqondiswe ngendlela ejwayelekile enezingqimba eziyi-10 kukhokhela iprimiyamu yentengo engu-15–30% ngaphandle kwenzuzo.

6.2 Uma i-HDI enezingqimba ezingu-8 idlula i-Standard enezingqimba ezingu-10

Icala lezomnotho liyashintsha uma:

• Izingxenye ze-BGA ku-0.5mm noma iphimbo elincane azikwazi ukufeza i-feniout ngama-via angena embobeni ebhodini elinezingqimba eziyi-10 ngaphandle kokuminyana okukhulu komzila
• Ukwehliswa kosayizi webhodi okunikwe amandla yi-HDI density kunenani lezinga lomkhiqizo (indawo encane evalekile, izindleko ze-BOM ezincishisiwe, indawo engcono emakethe)
• Ubuningi bomzila we-HDI enezingqimba ezingu-8 endaweni ethile budlula lokho ibhodi ejwayelekile enezingqimba ezingu-10 engakufeza — okusho ukuthi izinga lezingqimba ezingu-10 kuzodingeka libe yizingqimba ezingu-12 noma ezingu-14 ukuze lifane nobuningi, okudlula ngokushesha intengo ye-HDI.

Kumadizayini asemngceleni, sebenzisa zombili izinketho nge-DFM. Umphumela wokuqondisa — ikakhulukazi ukuthi ibhodi elijwayelekile lidinga izendlalelo ezengeziwe ukuze kube nobunzima obufanayo bomzila — unquma ukuthi yiluphi ulwakhiwo olungabizi kakhulu ngempela. Umklamo we-PCB we-Highleap kanye nensizakalo ye-DFM inikeza lolu hlaziyo ngaphambi kokuba kwenziwe izibopho zokukhiqiza.
