Abstract
The utility model discloses a prevent static flexible line way board is stacked gradually and is formed by metal thermal layer (1), polyimide heat -conducting layer (2), line layer (3) and overburden (4), the net layer of metal thermal layer for constituting by metal grid line, the net layer arrange by a plurality of positive square gridding and form, be equipped with a plurality of heat conduction post (5) between line layer and the metal thermal layer, the ground wire of leading in the electrical pillar and gate layer links to each other, positive square gridding's the length of side be 0.5 0.7mm, the width of gridlines be 0.01 0.04mm. This prevent static flexible line way board effect of thermal conductivity is good, and has good pliability.
Description
Technical field
This utility model is particularly to a kind of antistatic flexible wiring board.
Background technology
Flexible circuit board is generally located in the closing space within mobile phone, panel computer, often because poor heat radiation is led
Cause signal transmission impact, be additionally, since flexible circuit board and be easily subject to static interference, be easily caused device failure, therefore, having must
Design a kind of antistatic flexible wiring board.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of antistatic flexible wiring board, this antistatic flexible line
Road plate good heat conduction effect, and there is good pliability, there is good antistatic effect.
The technical solution of utility model is as follows：
A kind of antistatic flexible wiring board, by metallic radiating layer, polyimides heat-conducting layer, line layer and cover layer layer successively
Fold and form；
Described metallic radiating layer is the clathrum being made up of metal grid lines, and described clathrum is by multiple square nets
Grillages cloth forms；It is provided with multiple heating columns between line layer and metallic radiating layer；Conductive pole is connected with the ground wire in line layer；
The length of side of described square net is 0.5-0.7mm；The width of described grid lines is 0.01-0.04mm.
Preferably, the length of side of described square net is 0.6mm；The width of described grid lines is 0.025mm.
Beneficial effect
Antistatic flexible wiring board of the present utility model, using polyimide material as heat-conducting layer, polyimides have
Heat can rapidly be spread to metallic radiating layer, in addition, latticed metallic radiating layer is or not the characteristic of high heat conduction from line layer
But heat dispersion can be improved moreover it is possible to further enhance flexible circuit board overall pliability, the ground wire of line layer and heat dissipation metal
Layer is electrically connected by conductive pole, can strengthen antistatic and the interference free performance of flexible circuit board.Therefore, this flexible circuit board is special
It is not useful in clamshell phone occasion.
