Increase and increase, but also can increase simultaneously conducting particles contact with each other cause short circuit probability.The uniform particle sizes of conducting particles
Degree and distributing homogeneity also can affect on conductive characteristic.Conducting particles must have good uniform particle sizes' degree and proper circle
Degree, consistent to guarantee the contact area between electrode and conducting particles, maintain identical conducting resistance, and avoid partial electrode simultaneously
Not in contact with lead to conducting particles open a way.Conducting particles too conference reduces the population of each electrode contact, similarly simultaneously
Adjacent electrode conducting particles is caused to contact and the situation of short circuit；Too little conducting particles easily forms the problem of particle accumulation, makes
Become particle distribution density uneven.

It is pressed in the hot pressing face on flexible PCB, and described hot pressing face includes the hot pressing face I for being pressed on golden finger of flexible circuit board
With the hot pressing face II for being pressed in golden finger of flexible circuit board and this flexible PCB edge, the height of described hot pressing face II is higher than
The height of described hot pressing face I.
Further, described hot pressing face I and hot pressing face II are parallel to each other.
Further, the spacing between described hot pressing face I and hot pressing face II is equal to 0.10mm.
Further, it is provided with joint face between described hot pressing face I and hot pressing face II, described joint face is perpendicular to described hot pressing face
Ⅰ.
Further, the width of described hot pressing face I is equal to the length of golden finger of flexible circuit board.
Further, the width of described hot pressing face II is equal between golden finger of flexible circuit board and this flexible PCB edge
Width.
Further, also include pedestal, described hot pressing cutter hub is arranged on described pedestal.
Further, described hot pressing cutter hub and the setting of described pedestal are integrated.
The beneficial effects of the utility model are：
The anti-conducting particles of this utility model assembles the hot pressing cutter head of short circuit, by hot pressing face is set to hot pressing face I and heat
