Material Overview

Copper foil is made of copper and other metals in a certain proportion. It is an important material for copper clad laminate (CCL) and printed circuit board (PCB). In today's rapidly developing electronic information industry, electrolytic copper foil is called: the "neural network" for electronic product signal and power transmission and communication.
Difficulty in sample preparation: very soft, easy to cause scratches; ；easy to cause scratches; very thin, easy to over-grind.

Customer goal: After corrosion, the grain boundary is clearly visible.。

Sample preparation plan

Fixing:

Truer hot melt wax stick Hot melt wax can be melted after heating and the sample can be easily removed. Image

* After the standard sample is heated in the oven at 70 degrees, take it out, apply the hot melt wax stick evenly on the standard sample, place the copper foil, and fix it firmly after the sample cools down.
