五、Product description
The thermal conductive silica gel sheet is used to fill the air gap between the heating device the heat sink the metal base. Its flexible elastic characteristics enable it to cover the very uneven surface. Heat is transferred the separating device the whole PCB to the metal shell
on the diffusion plate, thereby improving the efficiency service life of the heating electronic components.
六、Storage
