4 Lakabka ENIG FR4+R04350 Lamination Mixed PCB

Mid ka mid ah caqabadaha ugu waaweyn ee codsiyada RF/microwave waa sida loo hubiyo in dulqaadka dhabta ah uu ku jiro dulqaadka naqshadeynta, si loo gaaro inta jeer ee hawlgalka ee la doonayo.Mid ka mid ah caqabadaha ugu waaweyn ee naqshadeynta lamination ee qaababka isku dhafan ee cadaadiska waa in la yeesho dhumuc isku mid ah inta u dhaxaysa darfaha kala duwan ama xitaa inta u dhaxaysa qaybo kala duwan.Sababtoo ah jiritaanka noocyo kala duwan oo noocyada walxaha substrate-ka ah, waxaa jira noocyo kala duwan oo xaashi ah oo la daaweeyay.

Rogers wuu ka duwan yahay xabagta epoxy PCB-ga caadiga ah.Dhexda ma jiro fiber galaas ah waana shay dhoobo ah oo ku salaysan inta jeer ee sarreeya.Inta jeer ee wareegga wareegga ee ka sarreeya 500MHz, kala duwanaanta agabka uu heli karo injineerka naqshadaynta ayaa si weyn loo dhimay.Waxyaalaha Rogers RO4350B si fudud ayaa loo samayn karaa wareegyada naqshadaynta injineernimada RF, sida isku-xidhka shabakada, xakamaynta xajinta gudbinta, iwmJoogtada dielectric ee isbedbedelka heerkulka ayaa ah ku dhawaad ​​kan ugu hooseeya ee isla walaxda.Oggolaanshaha sidoo kale si cajiib ah ayuu u deggan yahay 3.48 marka loo eego baaxadda soo noqnoqoshada ballaaran.3.66.Talooyinka naqshadeynta biibiile naxaasta ah ee Lopra si loo yareeyo luminta gelinta.Tani waxay ka dhigaysa walxaha ku habboon codsiyada ballaadhan.
