Description
Technical field
The present invention relates to display field, more particularly to a kind of flexible printed circuit board structure.
Background technology
Flexible printed circuit board (Flexible Printed Circuit, FPC) be using polyimides or polyester film as
It is a kind of made of base material that there is height reliability, the printed circuit board of excellent pliability.In the production process of liquid crystal display, lead to
Anisotropic conductive film (Anisotropic Conductive Film, ACF) and hot pressing Welding are crossed, FPC is tied to liquid crystal
On the pin for showing the connection structure of panel.
Invention content
Inventor the study found that flexible printed circuit board on the pin for the connection structure for being tied to liquid crystal display panel
When, hot pressing Welding typical temperature is used as between 180 DEG C~200 DEG C, when flexible printed circuit board is being tied to liquid crystal display
When on the glass panel of panel, influence substantially may be used caused by temperature substrate to made of glass material between 180 DEG C~200 DEG C
To ignore, however in the prior art, it is technologic demand, usually touch-control circuit is arranged on polaroid, this is just needed
By pin of the flexible printed circuit board on polaroid is tied to, and since polarizer material limits, heat-resistant quality is poor,
180 DEG C~200 DEG C of heat-resistant limits far beyond polaroid, this will cause polaroid to be scalded, it is made to turn to be yellow and is deformed upon, is made
Into touch control line poor flow, therefore how the signal on touch-control circuit is conducting to external circuit as a skill from polaroid
Art difficult point.For the technology, even with low temperature anisotropy conductiving glue (Anisotropic currently on the market
Conductive Film, ACF) it is bound, in order to ensure the reactivity of ACF, binding temperature needs to be arranged on 125 DEG C, although
Connection conduction is fine, but in binding procedure, to ensure that binding temperature is uniform, needs that thermal head area is set to be more than flexibility
Printed circuit board area, the heat radiation that such thermal head is more than the part of flexible printed circuit board can act directly on polaroid
On, polaroid can still have that part is turned to be yellow so that bad order.Inventor is it is discovered by experiment that low temperature
When anisotropic conducting resinl is bound, flexible printed circuit board is between thermal head and polaroid, the polaroid of the part
Since anisotropy conductiving glue and flexible printed circuit board absorb the heat radiation of a large amount of thermal head, so as to substantially non-yellowing,
But the part that no flexible printed circuit board blocks, heat radiation can be acted directly on polaroid, and polaroid yellowing phenomenon compares
Seriously.
