0.6-3.2mm thick FR4 Copper Clad Laminate Sheet, Single and Double Side Available

Description

FR4 Copper Clad Laminate sheet
 
Newlytrend Copper Clad Laminate FR4 (single or double sided)is a kind of copper foil covered laminated board formed through heat pressing after the electric industry alkali-free glass fiber dips into thermoset epoxy resins and is covered with copper foil at one side or both sides. Usually used in PCB with printed circuit on one or both sides of computers, home electric appliances and other lines.

C. Suggestion for use
Please baking the laminate at **0°C,2 hours before using.
Please pay attention to the machining for the interbedded energy is lower than the normal FR*4.Rilling parameters are mainly dependent on hole size ,layer thickness, layer number ,copper thickness and stack height.
The following drilling parameters are for reference only .Typical drilling parameters for 0.4 ~1.0mm drills are as follows:
speed :*5 ~**5 KRPM    
Feed rate:*0~**0 IPM
Retract rate:;**0~***0 IPM
Suggest hit count:***0 HITS
Stack height:≤2pnls(2~6 layers), 1pnls(≤8 layers)
Entry Material:0.2mm Aluminum
