Qaybaha xusuusta kombiyuutarka iyo kaadhadhka garaafyada, waxa jira saf ah xidhidhiyaha xidhidhiyaha dahabka ah, oo caadi ahaan loo yaqaan "faraha dahabka." Naqshadda PCB-ga iyo warshadaha wax-soo-saarka, farta dahabka ee PCB (Faraha Dahabka ama Xidhiidhiyaha Edge) waxa ay tilmaamaysaa xidhiidhiyaha loo isticmaalo is-dhexgalka dibadda ee PCB-ga si loogu xidho aaladaha dibadda. Maqaalkan, waxaan ku baari doonaa naqshadeynta "farta dahabka" ee PCB waxaanan ka wada hadli doonaa qaar ka mid ah tixgelinnada wax soo saarka ee muhiimka ah.
Hawlaha iyo Codsiyada Farta Dahabka ah
Barta isku xidhka ee farta dahabka ah Marka PCB-yada caawiya (sida kaadhadhka garaafyada ama modules-yada xusuusta) ay ku xidhmaan Motherboard-ka, waxay sidaas ku sameeyaan booska, sida PCI, ISA, ama AGP. Farta dahabka ah waxay u adeegtaa sidii barta isku xirka, taasoo u oggolaanaysa gudbinta calaamadaha u dhexeeya aaladaha durugsan ama kaararka gudaha iyo kumbuyuutarka.
Adapters gaar ah, Faraha dahabka ah, waxay kor u qaadi karaan shaqada Motherboard-ka iyagoo u oggolaanaya PCB-ga labaad in la geliyo. Tusaale ahaan, xusuusta, kaadhadhka garaafyada, kaadhadhka codka, kaadhadhka shabkada, iyo kaadhadhka kale waxay ku xidhmaan xidhidhka cidhifka ah. Xidhiidhadani waxay caawiyaan gudbinta sawirada iyo codka tayada sare leh. Maadaama kaadhadhkan ay naadir tahay in la saaro ama dib loo geliyo, farta dahabka ah ayaa caadi ahaan ka adkeysi badan kaarka laftiisa.
Xidhiidhka Dibadda ee Farta Dahabka ah Gawaarida dibedda sida kuwa ku hadla, subwoofers, scanners, printer, iyo bandhigyada waxay ku xiran yihiin Motherboard-ka iyada oo loo sii marayo PCB "farta dahabka." Qaybahan waxa lagu xidhay meelo gaar ah oo ku yaala dhabarka kombayutarka, sida HDMI, DisplayPort, VGA, ama DVI, kuwaas oo iyaguna ku xidha Motherboard-ka PCB-ga.
Tixgelinta Nakhshad Wax-soo-saarka ee Faraha Dahabka ah ee PCB
Naqshadeynta Farta Dahabka ah ee Bevel
- Fogaan badbaado leh oo ka imanaya Edge: Fogaanta u dhaxaysa farta dahabka iyo cidhifka PCB waa in lagu tixgaliyaa iyadoo lagu salaynayo dhumucda looxa iyo xagasha goysa ee “farta dahabka”. Xagasha gariir ee caadiga ah waa 45 darajo.
- Haddii farta dahabka ah la dhigo meel aad ugu dhow cidhifka looxa oo soo-gaadhista naxaasta aan la rabin, waa in wax laga beddelo si loo hubiyo fogaan badbaado leh oo u dhexeeya farta dahabka iyo cidhifka PCB si looga fogaado in la gooyo naxaasta.
Naqshadaynta daaqada Soldermask
- Si loo fududeeyo gelinta kaarka, meesha farta dahabka ah waa in ay leedahay meel furan oo ku taal maaskarada alxanka. Haddaysan ahayn, khad maaskarada u dhexeeya faraha dahabka ah ayaa laga yaabaa inay go'do inta lagu jiro gelinta soo noqnoqda, taasoo ka hortagaysa xiriir wanaagsan oo lala yeesho booska.
- Daaqadda farta dahabka ah ama meesha farta daasada ah waa in la furo wax yar ka weyn cidhifka PCB (qiyaastii 10 mayl).
- Daaqada sidoo kale waa in ay ka weynaataa raadadka 4 mil oo dhinac ah. Ka taxadar inaadan soo bandhigin naxaasta markaad fureyso daaqada; haddii kale, maarta waa in laga saaraa.
- Daaqadaha waa in aan lagu samayn agagaarka farta dahabka ah haddi ay ka yartahay 2 mm.
Hagaajinta cidhifka ee geesaha guddiga
- Si loo fududeeyo gelinta kaadhka, dulucda PCB ee farta dahabka u dhow waa inay lahaadaan geeso jeexan. Haddii la isticmaalo geeso jeexan ama wareegsan waxay kuxirantahay doorbidida naqshadeynta. Haddii geesaha aan la jeexin, xagasha saxda ah waxay dhaawici kartaa booska kaadhka inta lagu jiro gelinta iyo soo saarista, taasoo yaraynaysa kalsoonida alaabta.
Naqshadaynta Lakabka Copper ee Raadraaca
- Si ay u fududaato gelinta, waxa fiican in aanad naxaasta saarin dusha sare ee meesha farta dahabka ah. Haddii shabakado badan ay isticmaalaan raad isku mid ah, lakabka naxaasta ah wuxuu isku xiri karaa fara badan oo dahab ah, taas oo adkeyneysa in la geliyo ama la soo saaro kaararka.
Naqshadeynta "Faraha Dahabka ah" ee dhaadheer iyo kuwa gaaban
- Faraha dahabka ah ee dheer iyo kuwa gaaban, raadadka ugu weyn waa inuu ahaadaa 40 mils, raadadka labaadna 20 mils, iyo dhibcaha isku xirka 6 mils. Masaafada u dhaxaysa suufka "farta dahabka" iyo 20 mil waa in ay ahaataa 8 mayl.
- Marka raadka ugu weyni uu soo galo sabuuradda, waa in la mariyaa iyadoo la isticmaalayo xariiqyo gees leh. Haddii uu jiro darajo weyn oo u dhow farta dahabka, raadadku waa inay lahaadaan geeso wareegsan halkii ay ka ahaan lahaayeen xaglo fiiqan.
Naqshadeynta Gudida
- Haddii cabbirka sabuuradda farta dahabiga ah ay ka yar tahay 40 × 40 mm, gogosha waa in marka hore la farsameeyaa, oo ay ku xigto shiididda dulucda PCB. CAM waa in ay naqshadayso godadka meelaynta labada daraf ee PCB si ay u meelaynta sare. Goodhka otomaatiga ah waa inuu xaqiijiyaa in ballaca farta dahabka uu yahay ugu yaraan 40 mm.
- Marka la ciqaabayo, farta dahabka ah waa in ay u jeeddaa dibadda, iyada oo faraha dahabka ah ay u jeedaan gudaha si ay u fududeeyaan ku darida dahabka korantada.

Magdhawga CAM
- Waayo, PCB-yada lakabka badan Faraha dahabka leh, dhumucda naxaasta gudaha ah ee u dhow aagga farta dahabka waa inay ahaataa 80 mils ee alaabta caadiga ah iyo 40 mils ee alaabta indhaha ama xusuusta.
- Naqshadaynta aan lahayn faraha dahabiga ah, laakiin halka loo baahan yahay in la gooyo, lakabka naxaasta ah waa inuu sidoo kale raacaa xeerar la mid ah sida faraha dahabka.
- Balaadhka raadraaca farta dahabka ah waa inuu ahaadaa 12 mayl, iyadoo awoodda hadda ee farta dahabku ay tahay 40 mayl.
- Alaabooyinka indhaha ee isticmaalaya habka farta dahabka ah (dahab dahabka ah + isku xidhayaasha cidhifka), wax magdhow ah laguma dabaqo raadadka suufka. Fogaanta farta dahabka ah ilaa cidhifka PCB waa inay ahaataa ugu yaraan 0.5 mm. Haddii dhumucda looxa uu yahay +/- 0.1 mm, naxaas waa in lagu daraa meel bannaan oo ku wareegsan aagga farta dahabka ah si loo fududeeyo ciqaabta, iyo godadka aan birta ahayn ee 0.4 mm waa in lagu daraa geesaha qaybta "farta dahabka".
