The cost of a PCB is related to the board utilization, which cannot be defined by a proportional coefficient. For example, the dimensions of an original PCB substrate are 1200*1000mm, which can make 4pcs of 600*500mm board. Yet if it is a 610*500mm board, an original PCB can only make 3pcs, which means the cost is increased by 30% but the surface area is only increased by 1.6%.

Heat radiating grooves and vent holes are used for LED panels without heat sinks on the back. The aim is to improve the effect of heat dissipation by increasing the number of grooves.

V-scoring is used consistently in printed circuit board assembly because it is a great cost saver and a highly efficient way to offer easy separation of parts from a completed assembly.
