4.2 HCXX-BASE-EVM and 2HC08-MOD-EVM Assembly Drawings and Layout

The design of the HCXX-BASE-EVM and 2HC08-MOD-EVM printed-circuit board (PCB) is shown in Figure 4-2 to Figure 4-5. The EVM is designed using FR4 material, four-layer (2s2p), 2 × 70µm cubic inch top and bottom layers, and 2 × 35µm cubic inch internal plane layers. All components are in an active area on the top side and all active traces are in the top and bottom layers to allow the user to easily view, probe, and evaluate. Moving components to both sides of the PCB offers additional size reduction for space-constrained systems.
