Ngwa PCB RO4003C Rogers High Frequency PCB
Enwere ike wepu ihe RO4003C na ahịhịa nylon a na-ahụkarị.Achọghị njikwa pụrụ iche tupu electroplating ọla kọpa na-enweghị ọkụ eletrik.A ghaghị ịgwọ efere ahụ site na iji usoro epoxy/glass.N'ozuzu, ọ dịghị mkpa iwepụ olulu mmiri n'ihi na usoro TG resin dị elu (280°C+[536°F]) adịghị agba agba ngwa ngwa n'oge a na-egwupụta ihe.Ọ bụrụ na ọ bụ ọrụ mgbapu na-eme ihe ike kpatara ntụpọ ahụ, enwere ike wepu resin site na iji usoro plasma CF4/O2 ọkọlọtọ ma ọ bụ site na usoro permanganate abụọ alkaline.
Elu ihe RO4003C nwere ike ịbụ n'ụdị na / ma ọ bụ kemịkalụ kwadebere maka nchekwa ọkụ.A na-atụ aro ka iji ọkọlọtọ aqueous ma ọ bụ ọkara-aqueous photoresists.Enwere ike iji nhicha ọla kọpa ọ bụla dị na ya na-ere ahịa.Ihe mkpuchi niile a na-enyocha ma ọ bụ foto solderable nke a na-ejikarị eme ihe maka epoxy/glass laminates na-adabere nke ọma n'elu ro4003C.Mechanical ihicha elu dielectric ekpughere tupu etinye ihe mkpuchi ịgbado ọkụ na elu “edenyere aha ya” ga-ezere nrapanye kacha mma.
Ihe eji esi nri nke ihe ro4000 bụ nke epoxy/glass.N'ozuzu, akụrụngwa na-adịghị esi efere epoxy/glass adịghị mkpa esi nri ro4003 efere.Maka ntinye nke iko epoxy/baked dị ka akụkụ nke usoro a na-emekarị, anyị na-akwado isi nri na 300°F, 250°f (121°c-149°C) maka awa 1 ruo 2.Ro4003C enweghị ihe mgbochi ire ọkụ.Enwere ike ịghọta na efere etinyere na nkeji infrared (IR) ma ọ bụ na-arụ ọrụ na ọsọ nnyefe dị obere nwere ike iru okpomọkụ karịa 700°F (371°C);Ro4003C nwere ike ịmalite combustion na oke okpomọkụ ndị a.Sistemu ka na-eji ngwaọrụ reflux infrared ma ọ bụ akụrụngwa ndị ọzọ nwere ike iru oke okpomọkụ ndị a kwesịrị ịkpachara anya dị mkpa iji hụ na enweghị ihe egwu.
Enwere ike ịchekwa laminates dị elu ruo mgbe ebighị ebi na ụlọ okpomọkụ (55-85°F, 13-30°C), iru mmiri.N'ebe okpomọkụ dị n'ime ụlọ, ihe dielectric na-adịghị adị na oke iru mmiri.Otú ọ dị, mkpuchi ígwè dị ka ọla kọpa nwere ike oxidize mgbe ekpughere ya na iru mmiri dị elu.Ọkọlọtọ tupu ihicha PCBS nwere ike wepu corrosion n'ihe ndị echekwara nke ọma.
The RO4003C ihe nwere ike machined iji ngwaọrụ a na-eji maka epoxy / iko na ike metal ọnọdụ.A ga-ewepụrịrị foil ọla kọpa na ọwa ntuziaka iji gbochie mmetọ.
