“G” stands for glass fiber, “10” should means containing 10% in glass fiber. G10 materials has characteristics of insulation, corrosion-resistant, wear-resistant. It can be used as a knife handle. G10 is a kind of composite material with glass fiber cloth and epoxy resin laminated, was developed as the aircraft material… Continue Reading A kind of composite materials with glass fiber and resin laminated

When Non-flow prepreg is applied to the rigid-flex joint plate and the cold plate, neither the cold plate window region nor the junction of the rigid-flex joint plate is intended to flow excessively. But it is necessary for the basic flow-fill line when pressing. From the rheological point of view,… Continue Reading Non-Flow prepreg’s flowing glue when pressing

“No-flow” is the largest characteristic of the Non-Flow prepreg. This kind of plate has strict requirements to the flow ability of Non-Flow prepreg, to prevent flowing glue in the rigid-flex joint, the step slot, etc..From the melt viscosity curve of view of Non-Flow prepreg and conventional ordinary FR4 prepreg, the… Continue Reading Features Brief of Non-Flow Prepreg
