FR4 Copper Clad Laminate Sheet
Copper Clad Laminated SheetI
FR4 Copper Clad Laminate
Thickness:0.6mm,0.8mm,1.0mm,1.2mm,1.6mm,2.0mm .Thickness of copper:18um, 35um, other thickness is according to order. Face: 1 and 2 Size: 1020mm*1220mm Features: 1) The end face of foil covered board should be tidy without any delamination and crackle .2) Any bubble, wrinkle, pin hole, deep nick, pitting and glue spot on the copper foil covered face is not allowed. Any color changing or dirty can be easily. removed by density 1.02g/cm3 hydrochloric acid or proper organic solution .3) On laminated face, the defects such as bubble, impressed pitting, nick and glue lack and outer impurity which retard its use are not allowed .4) Usually used in PCB of computers, home electric appliances and other lines.
