by the way:
If we place an order for the wireless circuit of single-sided aluminum substrate, it is best to note whether or not to add thermal conductive glue, otherwise PCBWay will confirm with you whether thermal conductive glue is needed. The thermal conductive glue is milky white. The white part in the picture.
