Looking for FPC manufacturer? BEST Technology can manufacture 2L FPC with 2 mil adhesiveless PI, ENIG(2u”) surface treatment.
FPC manufacturer, Adheiveless PI FPC.
This design used 2 mil adhesiveless PI. Do you know the advantages of adhesiveless PI?
1. Thinner Thickness
As you know, the thickness of adhesive is around 12um, 15um, 20um, 25um, 50um. If you have strict requirement for the whole board thickness, it will be a good choice to use adhesiveless PI.
2. Better Bending
Adhesiveless substrate is thinner than adhesive substrate, so it’s bending is better.
3. Heat resistance
Due to the adhesive have poor performance in heat resistance, so without the adhesive, the adhesiveless base material have better heat resistance.
Under the same temperature, such as 200℃，the tearing strength of adhesiveless PI change a little. But the tearing strength of adhesive PI material rapidly decrease.
4. Dimensional stability
The dimension of adhesiveless board change very small when the temperature increase. Even under the temperature of 300℃, it’s dimensional changing rate is no more than 0.1%.
Good dimensional stability will be great help for fine wiring process.
