Suggestion for use
Please baking the laminate at 150°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 :45 ~105 KRPM
Feed rate:50~150 IPM
Retract rate:;500~1000 IPM
Suggest hit count:1500 HITS
Stack height:≤2pnls(2~6 layers), 1pnls(≤8 layers)
Entry Material:0.2mm Aluminum
