Comparison
|
Suitable flexibility can perform well when stretching the stencil |
The over-flexibility of wire net causes the difficulty to control the scraper pressure and make improper bounce |
|
Thickness of stencil
|
15um ~ 150um
|
> 20um
|
|
Comparison
|
All the holes are on the same surface, and this make the thinner stencil possible |
The wire have to lie over each other, and cause the difficulties in producing thinner wire net |
|
Density of opening holes
|
Max: 15000 holes/cm2
|
500~600mesh
