1.Solder Mask Bridge: The oil between two pins of component is solder mask bridge, generally refers to intensive IC pin (check the below picture). If the distance of pin is too small, it will be recommended to cancel the solder mask bridge and take advantage of solder mask opening technology.

2.Solder Mask Openings: the place without solder mask calls solder mask opening

3.PCBWay can accept the minimum distance between IC pins is 0.2mm (check the below picture), if the distance less than 0.2mm, we recommend to do solder mask openings
