HAL process creates
The HAL process creates the surface of the circuit board with a tin bath.
The fluid tin forms "drops" on the surface areas and runs along the edged of holes and pads.

Consider solder problems with HAL PCB
This causes the surface of the circuit board to be very thin right at the edges, and may lead to solder problems.

A uniform surface thickness cannot be achieved with HAL.
