The first and second ribbon bonds each has a first end connected to the first circuit component and a second end connected to the second circuit component. An upstanding barrier structure extends on multiple sides of the first and second circuit components and has a ribbon bond guard extending at least partially over the first and second ribbon bonds. A separator extends downward from the ribbon bond guard and at least partially between the first and second ribbon bonds. ## Claims ### Claim 1 A circuit board assembly comprising: a circuit board having a circuit mounting surface;
