1.Usage
Primarily be applicable to high-end and precision PCB drilling. Good surface flatness, moderate hardness and density, can effectively reduce
the bit of wear and extend bit life and reduce production costs.
2. Introduction
a) hardwood material can be avoided burr when drilling;
b) the main raw material belong to 100% pure wood pulp, with no impurities and Particles
c) good surface flatness, to avoid hole shift,wear of drill;
d) wood from the tropical forests, thus anti-moth, anti-termite;
e) good material, the smaller the impact of climate change on the warpage.
3.Storage
a) a relative humidity of 80% or less, at room temperature;
b) stretch the whole cover, is not directly exposed to the air, to cut off contact with moisture and the board;
c) the height of each pallet should be no more than 4 levels;
d) when in wet weather, if open stretch film, try to use it up within 48 hours, in order to prevent deformation of
the absorbent sheet.
