| Film selection method
|
| |
| Functions of films |
|
Required functions |
Items to check |
Film area |
Heat contraction ra |
Check a width difference of the base and laminex films when joining them. |
Moisture entry prevention structure |
Check if reflected in the film design. |
Adhesion for peeling |
Peel off the film to check. |
Scratches on the surface |
Visually check for holes or cuts. |
Insulation condition |
Line tape : Check if vinyl or transparent OPP is used.
Plane tape : Check if the PE material is thick enough. |
Hardening |
Check if the heat value is sufficient by testing the ohm(Ω) resistance. |
Copper area |
Copper width |
The wider the better it prevents overheating during conduction. |
Copper thickness |
The narrower the film intervals are, the better it prevents sparks. |
Types of copper |
Tough pitch copper(pure copper)'s conduction rate is 106%
Phosphorous deoxidized copper is 86%. |
Types of permissions |
Check according to the thickness and the width. |
Printing area |
Regular carbon surface |
Check it with a microscope. |
Spark prevention design |
See if a structure to prevent sparks is reflected in the carbon printing design. |
