The first excessive glue portion, the second excessive glue portion and hot-melt adhesive paste portion are set on layer, can be occurred to avoid when carrying out wrapped protection band
Be uneven whole problem, it can difference in height occurs in the protection band of the protection band and non-overlap that avoid lap, protects
Demonstrate,proving high frequency data transfer line has smooth and symmetrical structure;Also, the protection band due to lap can also be avoided to go out
Now one layer of the protection band problem that shield effectiveness occur poor more than the protection band of not lap, at the same time it can also
It avoids the protection band of lap and does not occur subtle gap between the protection band of lap, improve high-frequency data
The stability of transmission line structure reduces the high frequency data transfer performance of high frequency data transfer line.
