From the project

Environmental RFI monitoring system for the NRAO VLA

- New thermal via grid underneath U2 for temperature management - Layer 2 DGS underneath L1,L2,C1,C2,C3,C4 as follows: - Shunts L1,L2,C3,C4: 0.60mm x 0.1mm (trace pad) - Series C1,C2: 1.5mm x 0.5mm

- Changed mouting pad dimensions of L1,L2,C1,C2,C3,C4 to 0.56mm x 0.62mm rounded rectangle. Previous values: - Shunts L1,L2: 0.37mm x 0.72mm rounded rectangle (trace pad) and 0.59mm x 0.64mm rectangle (bias pad) - Series C1,C2: 0.56mm x 0.37mm rounded rectangle (both) - Shunts C3,C4: 0.37mm x 0.72mm (trace pad) and 0.56mm x 0.62mm (bias pad) - Increased clearance around trace components from 0.2mm…
