Ehe kune nzira dzine bhajeti rekurasikirwa rakafanana nekuvakwa kweDf pakati pekurasikirwa. Hazvifanirwe kufungidzirwa kuti zvakakodzera kune nzira refu dze56G/112G PAM4 dzisina simulation uye correlation ye coupon.
Dhizaini inofanira kukwidziridzwa riini?
Kuvandudza kana nzira yese isina kurasikirwa mushure mekugadzirisa topology, kana kushushikana kwekupisa/kubatana kwakapfuura kuvakwa kweIT-150GS kwakakodzera, kana kana kutevedzera mitemo chaiyo kana zvinodiwa nevatengi zvichida imwe giredhi.
Saka chinyorwa cheIT-150GS chinonyanya kudzivirirwa igwaro rekusarudza rakavimbika: rinotaura nezvekukundikana kungangoitika, rinoratidza kuti kuunganidzwa uye maitiro zvinodzivirira sei, rinoona humbowo hunodiwa pachinyorwa chekutanga, uye rinotsanangura kuti chinotsiva chepasi kana chepamusoro chinogamuchirwa riini.
Mareferensi emugadziri uye manotsi ekuburitsa
Mareferensi everuzhinji eITEQ ari pazasi anotsigira nzvimbo yezvinhu-mhuri uye kukosha kwekuenzanisa kwakataurwa mubhuku rino. Nekuti data rakadzama rekupisa, zvivakwa, uye kuwanikwa kwenzvimbo zvinogona kutsamira pakudzokorora, package yequotation inofanira kusanganisira datasheet reIT-150GS riripo uye kusimbiswa kweprepreg kwakafanana.

Nzira yekuwana sei quote yePCBs
Ngatiite ongororo yeDFM/DFA kwauri tobva tadzoka kwauri nemushumo. Unogona kurodha mafaira ako zvakachengeteka kuburikidza newebhusaiti yedu. Tinoda ruzivo runotevera kuti tikupe mutengo:
-
- Gerber, ODB++, kana .pcb, spec.
- BOM rondedzero kana iwe uchida kusangana
- uwandu
- Kuchinja nguva
Kune masevhisi ePCBA, ndapota ipa BOM yako (Bhiri reZvinhu) uye chero mirairo yegungano. Isu tinopawo DFM/DFA ongororo yekukwidziridza zvigadziriso zvako zvekugadzira uye kusangana, kuve nechokwadi chekuita kwakatsetseka kwekugadzira.
