Kana dhizaini yako yemagetsi ikapfuura miganhu yePCB dzine layer 6, unoda mabhodhi edunhu akadhindwa ane layer 8. PCB ine layer 8 ine layer sere dzemhangura dzinofambisa mhepo dzakaparadzaniswa nezvinhu zve dielectric, zvichipa kuvimbika kwepamusoro kwesignali, kudzivirira electromagnetic uye kugoverwa kwesimba. Mabhodhi aya ane layer akawanda akakosha pakushandisa komputa yepamusoro, kutaurirana, masisitimu emotokari epamusoro, uye mashandisirwo emuchadenga uko magadzirirwo ane layer 6 asingakwanise kupa mashandiro anodiwa.
Gwaro iri rakazara rinokubatsira kunzwisisa nguva yekuvandudza kubva kumaPCB ane layer 6 kusvika ku8-layer, maitiro ekugadzirisa stack-up configuration yako, dhizaini yemasaini anomhanyisa, kudzora mitengo, uye kuona kuti kugadzirwa kwakanaka. Ungave uchigadzira maseva, 5G infrastructure, kana automated vehicle controllers, chinyorwa chino chinopa ruzivo rwehunyanzvi rwaunoda.
Chii chinonzi PCB ine 8-Layer uye Unoida Rini?
PCB ine zvidimbu zvisere inoumbwa nezvidimbu zvisere zvemhangura zvinofambisa mhepo zvakarongedzwa nezvinhu zvinodzivirira kupisa pakati pazvo. Unoronga zvikamu izvi sezvikamu zvezviratidzo, mapurani epasi, uye mapurani emagetsi. Zvikamu zvemhangura zvinopa nzira dzezviratidzo nesimba, nepo mapurani epasi achipa nzira dzekudzoka uye dziviriro yemagetsi.
Bhodhi redunhu rakadhindwa rine ukobvu hwe1.6mm rine 8-layer rine macores akawanda nezvinhu zvekugadzirira zvakabatanidzwa panguva yelamination. Unogadzirisa layer stack-up zvichienderana nekuvimbika kwesignali yako, kugoverwa kwesimba, uye zvinodiwa zveEMI. Sarudzo yega yega yedhizaini inokanganisa mashandiro, saka unofanirwa kuronga marongero elayer yako nekungwarira usati wagadzira.
Nguva Yekusimudzira Kubva pa6-Layer kuenda pa8-Layer
Unofanira kusimudzira kubva pa6-layer kuenda ku8-layer PCBs paunosangana nematambudziko aya:
- Zvinodiwa zvemasaini ekumhanya kwepamusoro: Dhizaini yako inoshandisa DDR5 memory, PCIe Gen 4/5, kana 100G Ethernet inoda kuvimbika kwemasaini kuri nani kupfuura kunogona kupihwa ne6-layer.
- Kugoverwa kwesimba kwakaoma: Unoda ma domains akawanda emagetsi (3.3V, 5V, 12V, 1.8V, 1.2V) ane ma planes emagetsi akagadzirirwa kupa simba rakachena.
- Kuwanda kwenzira: Kuiswa kwechikamu chako kunoda nzvimbo yakawanda yenzira inopfuura inogona kugarwa nezvikamu zvitanhatu
- Kudzora EMI: Unofanira kusangana nemazinga akasimba ekubatana kwemagetsi anoda mamwe mapuraneti epasi
- Kumhanya kwezviratidzo kuri pamusoro pe10 Gbps: Ma serial links ako anomhanya zvakanyanya anoda stripline routing ine dual reference planes
- Kutarisira kupisa: Mamwe marara emhangura anobatsira kuparadzira kupisa kubva muzvinhu zvinoda simba rakawanda
Magadzirirwo Akajairwa ePCB ane Zvikamu Zvisere
Kurongeka kwestack-up yako kunosarudza mhando yesignal, kuvimbika kwesimba, uye mashandiro eEMI. Unofanira kusarudza kurongeka kunoenderana nezvinodiwa nedhizaini yako. Anotevera marudzi matatu makuru estack-up ane layer 8:
Rudzi 1: Kuunganidzwa Kwakajairwa (Kwakajairika)
Iyi ndiyo gadziriro ine 8-layer inonyanya kushandiswa pakushandisa kwakajairika. Unowana kuvimbika kwakanaka kwesignali nekugoverwa kwesimba kwakanaka:
- Chikamu 1: Chiratidzo Chepamusoro (Rutivi rweChikamu)
- Danho rechishanu: Ndege Yepasi (GND)
