About Copper Clad Laminate (CCL) Sheets
What is Copper Clad Laminate?
Copper Clad Laminate, abbreviated to CCL, is a type of base material of PCBs. With glass fiber or wood pulp paper as reinforcing material, a copper clad board is a type of product through lamination with copper clad on either one side or both sides of reinforcing material after being soaked in resin.
How are CCLs Classified?
According to different classification standards, CCLs can be classified into various categories:
- Based on CCL mechanical rigidity, we have rigid CCL (FR-4, CEM-1, etc.) and flex CCL. Rigid PCBs depend on rigid CCLs while flex PCBs are on flex CCLs (flex-rigid PCBs are on both rigid CCLs and flex CCLs).
- Based on insulation material and structures, we have organic resin CCL (FR-4, CEM-3, etc.), metal-base CCL, ceramic-base CCL etc.
- Based on CCL thickness, we have standard thickness CCL and thin CCL. The former one requires at least 0.5mm thickness while the latter can be thinner than 0.5mm. Copper foil thickness is excluded from CCL thickness.
- Based on reinforcing material types, we have glass fiber cloth base CCL (FR-4, FR-5), paper base CCL (XPC), compound CCL (CEM-1, CEM-3).
- Based on applied insulation resin, we have epoxy resin CCL (FR-4, CEM-3) and Phenolic CCL (FR-1, XPC).
A material that is the basis of all circuits and printed wiring boards, and ultimately forms electronic circuits on the surface and is used as printed wiring boards.
Applications :
- General electronic circuit board applications
- High-speed communication applications (4G-LTE, 5G base stations / Radar applications)
- Automotive-ADAS_Radar uses
- Avionic-Radar uses
- Applications range from communications, automobiles, aerospace, and more.
