Do pcb circuit board which several kinds of plate
Fiberglass cloth based composite base paper - based synthetic fiber - based non - woven base
PCB circuit board plate mainly in the following categories:
First, FR-1:
Flame Retardant Copper Foil Phenolic Paper Laminate. IPC4101 detailed specification number 02; Tg N / A.
Second, FR-4:
1) Flame Retardant Copper Foil Epoxy E Glass Fiber Cloth Laminate and Its Adhesive Sheet Material. IPC4101 detailed specification number 21; Tg ≥ 100 ℃;
2) Flame Retardant Copper Foil Modified or Unmodified Epoxy E Fiberglass Laminated Laminate and Bonding Sheet Material. IPC4101 detailed specification number 24; Tg 150 ° C to 200 ° C;
3) Flame Retardant Copper Foil Epoxy / PPO Glass Cloth Laminate and Its Adhesive Sheet Material. IPC4101 detailed specification number 25; Tg 150 ° C to 200 ° C;
4) flame retardant copper clad modified or unmodified epoxy glass cloth laminate and its adhesive sheet material. IPC4101 detailed specification number 26; Tg 170 ℃ ~ 220 ℃;
5) Flame Retardant Copper Foil Epoxy E Glass Cloth Laminate (for Catalytic Addition). IPC4101 detailed specification number 82; Tg N / A;
Divided into two categories: rigid substrate materials and flexible substrate materials. Ordinary rigid substrate material is an important varieties of CCL.
Copper brass board classification of a variety of ways. Generally, the reinforcing material of the plate is divided into five categories: paper base, glass fiber cloth base, composite base (CEM series), laminated multilayer plate base and extraordinary material base (ceramic, metal core base). If the board is adopted by the resin adhesive different classification, the common paper-based CCI. There are various types such as phenolic resin (XPc, XxxPC, FR-1, FR-2, etc.), epoxy resin (FE-3), polyester resin and the like. Common glass fiber cloth CCL has epoxy resin (FR-4, FR-5), which is the most widely used glass fiber cloth type. In addition, there are other extraordinary resin (glass fiber cloth, polyamide fiber, non-woven fabrics to increase the material): bismaleimide modified triazine resin (BT), polyimide resin (PI) , Diphenylene ether resin (PPO), maleic anhydride imide-styrene resin (MS), polycyclic ester resin, polyolefin resin, and the like.
According to CCL flame retardant performance classification, can be divided into flame retardant (UL94 a VO, UL94 a V1 level) and non-flame retardant (UL94 a HB class) two types of boards. Nearly two years, with the environmental issues more attention, in the flame retardant CCL and separate a new non-brominated species of CCL species, can be called "green flame retardant cCL". With the rapid development of electronic products technology, the cCL has a higher performance requirements. Therefore, the performance classification from the CCL is divided into general performance CCL, low dielectric constant CCL, high heat resistance CCL (general plate L above 150 ℃), low thermal expansion coefficient CCL (generally used for packaging substrate ) And other types.
