RF PCB
Si loo daboolo baahiyaha sii kordhaya ee loogu talagalay Microwave & RF Looxyada Daabacan ee loogu talagalay macaamiisheenna adduunka oo idil, waxaan kordhinnay maal-gashigeennii sannadihii la soo dhaafay si aan u noqonno soo-saare heer caalami ah oo PCBs ah oo isticmaalaya laminates-ka sarreeya.
Codsiyadaani waxay sida caadiga ah u baahan yihiin laminates leh takhasus gaar ah oo koronto, kuleyl, farsamo, ama astaamo waxqabad oo ka sarreeya kuwa caadiga u ah qalabka FR-4. Sanado badan oo aan khibrad u leenahay laminate microwave-based PTFE, waxaan fahamsanahay kalsoonida sare iyo shuruudaha dulqaadka adag ee codsiyada badankood.
Qalabka PCB ee loogu talagalay RF PCB
Dhammaan astaamaha kala duwan ee dalab kasta oo PC PCB ah, waxaan la samaynay iskaashi lala yeelanayo alaab-qeybiyeyaasha muhiimka ah sida Rogers, Arlon, Nelco, iyo Taconic si aan u xusno wax yar. In kasta oo qalabkani uu aad u takhasus badan yahay, haddana waxaannu ku haynaa wax soo saar muhiim ah bakhaarkeenna Rogers (4003 & 4350 taxane) iyo Arlon. Ma ahan shirkado badan oo diyaar u ah inay sameeyaan taas marka loo eego kharashka badan ee qaadista alaabada si ay awood ugu yeeshaan inay si dhakhso leh uga jawaabaan.
Guddiyada wareegga teknolojiyadda sare ee lagu farsameeyo laminateska soo noqnoqda badan way adkaan kartaa in la naqshadeeyo sababtoo ah xasaasiyadda calaamadaha iyo caqabadaha ku saabsan maareynta wareejinta kuleylka kuleylka ee dalabkaaga. Qalabka PCB-ga soo noqnoqda fiican ayaa leh kuleylka kuleylka oo ka hooseeya heerka caadiga ah ee loo yaqaan 'FR-4' ee loo isticmaalo heerka PCB-yada.
RF iyo signalada microwave-ka ayaa aad ugu nugul dhawaqa waxayna leeyihiin dulqaad dheeri ah oo ka adag tan golayaasha wareegga dhijitaalka ah. Adoo adeegsanaya qorshooyinka dhulka isla markaana adeegsanaya gacan ballaadh badan oo leexsan oo ku saabsan raadadka kontoroolka xakamaynta ayaa gacan ka geysan kara samaynta naqshadeynta habka ugu hufan.
Sababtoo ah dhererka wareegga wareegga ayaa ah mid ku tiirsan iyo walxaha ku tiirsan, qalabka PCB ee leh qiyaasta sare ee korantada (Dk) waxay sababi kartaa PCBs yar yar maadaama naqshadaha wareega wareega loo isticmaali karo caqabado gaar ah iyo kala duwanaansho soo noqnoqda. Mararka qaar lakabadaha sare ee Dk sare (Dk 6 ama wixii ka sareeya) ayaa lagu daraa qiimo jaban qalabka FR-4 si loo abuuro naqshado isku dhafan oo iskudhaf ah.
Fahmitaanka isku dheelitirka balaarinta kuleylka (CTE), korantada korantada, isugeynta kuleylka, iskucelceliska heerkulka korantada korantada (TCDk), isugeynta faafitaanka (Df) iyo xitaa walxaha sida ogolaanshaha qaraabada, iyo luminta walxaha PCB ee la heli karo ayaa caawin doona RF PCB naqshadeeye wuxuu abuuraa naqshad adag oo ka badnaan doonta waxyaabaha laga filayo.
Awoodaha Baaxadda Leh
Marka lagu daro istaandarka Microwave / RF PCB-yada aan awood u leenahay adoo adeegsanaya laminates PTFE sidoo kale waxaa ka mid ah:
Guddiyada Isku-dhafan ama Isku-dhafan ee Isku-dhafan (isku-darka PTFE / FR-4)
Birta Taageerta iyo PCBs Birta Muhiimka ah
Guddiyada Godka (Farsamo iyo Laser Qoday)
Edge dahaadhay
Xiddigaha
Foomamka PCB-yada waaweyn
Indhoole / La aasay iyo Laser Via's
Dahab dahab ah iyo dahaadh ENEPIG
Bir Xudunta PCB
Mashiinka Aaladda Daabacan ee Birta ah (MCPCB), ama PCB-da kuleylka leh, waa nooc PCB ah oo leh wax bir ah oo saldhig u ah qaybta kuleylka kuleylka ee guddiga. Ujeedada udub dhexaadka MCPCB waa in kuleylka laga weeciyo qaybaha muhiimka ah ee guddiga iyo meelaha muhiimka u ah sida taageerada birta ee birta ama xudunta birta ah. Biraha hoose ee MCPCB waxaa loo adeegsadaa bedel ahaan looxyada FR4 ama CEM3.
Qalabka PCB-ga Birta ah iyo dhumucdiisuna
Xudunta birta ee PCB-da kuleylka waxay noqon kartaa aluminium (aluminium udub dhexaad u PCB), naxaas (PCB naxaas kobbar ah ama PCB naxaas culus) ama isku dar ah aalado gaar ah. Tan ugu caansan waa aluminium asaasiga ah PCB.
Dhumucda udub dhexaadka biraha ee taarikada saldhigga PCB caadi ahaan waa 30 mil - 125 mil, laakiin taarikada qaro weyn iyo dhuuban ayaa suuragal ah.
MCPCB dhumucda bireed copper waxay noqon kartaa 1 - 10 oz.
Faa'iidooyinka MCPCB
MCPCBs waxay faa'iido u yeelan karaan inay u adeegsadaan awooddooda inay dhexgalaan lakabka polymer dielectric oo leh hago kuleyl sare oo iska caabin ah kuleylka hoose.
PCB-yada muhiimka u ah birta waxay wareejiyaan kuleylka 8 ilaa 9 jeer ka dhaqso badan FR4 PCBs. MCPCB waxay dahaarisaa kuleylka faafiya, haynta kuleylka dhaliya qaybaha qaboojiyaha taasoo keenta waxqabad kordha iyo nolosha.
