The pad will open by default in the PCB design (OVERRIDE: 0.1016mm), that is, the pad exposed copper foil, the outer expansion is 0.1016mm, and the wave soldering will be tinned.TOP/BOTTOM SOLDER (top/bottom solder mask green oil layer): The top/bottom layer is coated with solder resist green oil to prevent tin on the copper foil and keep it insulated.Ī solder resist green soldermask opening can be placed on the pads, vias, and non-electric traces of this layer. The PCB design can be used to set the opening on the TOP/BOTTOM SOLDER layer.

Adding a loosemask area to the pcb effect reveals a yellow copper. Other non-local networks should not pass through the Soldmask. At the same time as adding the Soldmask, we need to spread the network copper in the add mask area, and we must cover the Soldmask plane, otherwise the pcb substrate (FR4, etc.) will be exposed. If you need to add a stencil, you need to confirm with the customer. If the customer needs to add a shield, then all we have to do is add a Soldmask with a width of at least 1mm. According to the actual situation, let’s take a look at several sets of pictures to explain. In our design, we often encounter customers who need to add shields, partial bright copper on the board side, through-hole open-resistance soldering, copper on the back side of the IC heat sink, and scratch pad. Because the customer is also ignorant or we are not too clear about this process, it is very troublesome to communicate. In the design, customers often ask for opening and bright copper.
