F4B-1/A1(Cu) Woven-glass PTFE Aluminum-clad (copper)Substrate
  This product is based on the woven-glass PTFE laminate substrate but it varies only with a copper roil-clad on one side and an aluminum sheet-clad(copper sheet)on the other side of it.Thus,this makes it to be a microwave printed-circuit substrate with one side for use as a ground plate.
※Technical Specifcations:
1、Dimension(mm):400×400;300×300
2、Thickness of Groud Plate:At customers'choice.
3、Flexibility Factory:Accord with the specifications of the substrate design deired.
