Habka wax soo saarka ee looxyada multilayer guud ahaan waxaa lagu sameeyaa sawirada lakabka gudaha ah marka hore, ka dibna habka daabacaadda iyo dhejinta si loo sameeyo hal dhinac ama labajibbaaran, iyo dhexda lakabka loo qoondeeyey inta u dhaxaysa, ka dibna kuleylinta, riixida iyo isku-xidhka. marka la eego qodista soo socota waxay la mid tahay habka laba-geesoodka ah ee lagu dhejiyo daloolka.
1. Marka hore, guddiga wareegga FR4 waa in marka hore la soo saaro.Ka dib marka lagu dhejiyo naxaasta daloolsan ee substrate-ka, godadka waxaa ka buuxsamay resin, xariiqyada dushana waxaa lagu sameeyaa xoqid kala-goys ah.Talaabadani waxay la mid tahay guddiga guud ee FR4 marka laga reebo buuxinta daloolinnada xabagta.
2. Xayawaanka epoxy-ka ee loo yaqaan 'photopolymer epoxy resin' waxaa lagu dabaqaa lakabka ugu horreeya ee dahaarka FV1, ka dib marka la qalajiyo, sawir-qaadista waxaa loo isticmaalaa tallaabada soo-gaadhista, ka dib soo-gaadhista, dareeraha ayaa loo isticmaalaa si loo horumariyo daloolka hoose ee godka birta.Adkeynta resinka waxaa la sameeyaa ka dib furitaanka daloolka.
3. Dusha sare ee xabagta epoxy waxaa lagu qallajiyaa etching acid permanganic, ka dib etching, lakabka naxaasta ah ayaa ka sameysan dusha sare ee dahaadhka naxaasta aan korantada lahayn ee tallaabada xigta ee naxaasta.Ka dib marka la dhajiyo, lakabka kooraska naxaasta ayaa la sameeyay waxaana lakabka salka uu ku sameeyay xoqid kala goyn.
4. Lagu dahaadhay lakabka labaad ee dahaarka, iyada oo la adeegsanayo tillaabooyinka horumarinta soo-gaadhista ee isku midka ah si loo sameeyo dalool godka hoostiisa ah.
5. Haddii baahida loo qabo dalool, waxaad isticmaali kartaa dalool dalool in ay sameeyaan daloolin ka dib markii formation of copper electroplating etching si ay u sameeyaan silig.
lakabka sare ee wareegga wareegga oo lagu daboolay rinjiga anti-tin, iyo isticmaalka habka horumarinta soo-gaadhista si loo muujiyo qaybta xiriirka.
6. Haddii tirada lakabyadu korodho, asal ahaan kaliya ku celi tallaabooyinka sare.Haddii ay jiraan lakabyo dheeraad ah oo labada dhinac ah, lakabka daboolka waa in lagu daboolaa labada dhinac ee lakabka saldhigga, laakiin habka dhejinta ayaa lagu fulin karaa labada dhinac isku mar.
