the four edges of the board have metallized half hole design, the aperture of the finished boards is small and the hole space is small. Half hole boards is generally used in bluetooth module and security monitoring module.
in the process of the manufacturing PCB, it needs to design special procedure to ensure the half hole of the boards to be metalized, and without metal burr
for the production process is more longer, so generally the lead time of this kind of board will be extended for 1-2 days
the boards with half hole design can't do gold plating finish, but you could choose ENIG , HASL and HASL LF
