Kudumisha uadilifu wa ishara kwa masafa ya juu inahitaji udhibiti wa uangalifu wa kuwaeleza, Kupunguza Crosstalk, na kutekeleza mbinu bora za kutuliza na kukinga.
Sehemu ndogo lazima iwe na nguvu ya kutosha ya mitambo na utulivu wa kuhimili michakato ya utengenezaji na hali ya utendaji, ikiwa ni pamoja na baiskeli ya joto na mkazo wa mitambo.
Upeo wa uso lazima uwe nyororo na usio na kasoro ili kuhakikisha ushikamano na upatanishi sahihi wa vipengele na kupunguza upotevu wa mawimbi na uakisi..
Materials Used in RF Package Substrates
Several materials are commonly used in the manufacturing of RF Package Substrates:
Nyenzo kama vile alumina (AL2O3), alumini nitridi (Aln), na oksidi ya berili (BeO) kutoa mali bora ya dielectric na conductivity ya juu ya mafuta.
Laminates ya juu-frequency, kama vile PTFE (Polytetrafluoroethylene) na composites za PTFE zilizojaa kauri, kutoa maadili ya chini ya dielectric mara kwa mara na hasara tangent, kuhakikisha upotezaji mdogo wa ishara.
Copper na aloi zingine za chuma hutumiwa kwa athari za kuvutia na vias kwa sababu ya ubora wao bora wa umeme na kuegemea.
Resini za epoksi zenye utendaji wa juu hutumiwa kama nyenzo za wambiso ili kuunganisha tabaka za substrate pamoja., Kutoa nguvu ya mitambo na utulivu.

Manufacturing Process of RF Package Substrates
The manufacturing process of RF Package Substrates involves several precise steps:
Malighafi, ikiwa ni pamoja na kauri za utendaji wa juu, laminates ya kikaboni, na aloi za chuma, zimeandaliwa na kusindika kuwa shuka au filamu.
Tabaka nyingi za nyenzo za substrate zimeunganishwa pamoja kuunda muundo wa kujenga-up. Utaratibu huu unajumuisha kutumia joto na shinikizo kushikamana tabaka.
Mifumo ya mzunguko imeundwa kwa kutumia michakato ya Photolithographic. Filamu ya picha (Mpiga picha) inatumika kwa substrate, wazi kwa ultraviolet (UV) mwanga kupitia mask, na kukuzwa kufunua mifumo inayotaka ya mzunguko. Sehemu ndogo huwekwa ili kuondoa nyenzo zisizohitajika.
VIAs huchimbwa kwenye substrate ili kuunda miunganisho ya umeme wima kati ya tabaka tofauti. Shimo hizi huwekwa na shaba ili kuanzisha njia za kusisimua.
laini, kumaliza uso usio na kasoro hutumiwa kwa usafi wa mawasiliano ili kuhakikisha kujitoa sahihi na usawa wa vipengele, pamoja na kupunguza upotevu wa ishara na kutafakari.
Sehemu ndogo zilizokamilishwa hupimwa na kukaguliwa kwa uangalifu ili kuhakikisha kuwa zinakidhi vipimo vinavyohitajika vya utendakazi wa umeme, Uadilifu wa ishara, na kuegemea.
