Thought for a moment

Vou corrigir especificamente as sobreposições dos pads EP de U3/U4. Vou revalidar os alertas atuais, identificar se são pads/mounts internos do footprint e ajustar as regras/propriedades desses nós sem mexer no posicionamento do AFE.

Thought for a moment

Entendido — vou priorizar a guarda WE em VCM_1V25 ao redor de U2 IN-. Antes de rotear, vou tentar limpar os alertas dos pads EP de U3/U4 para não contaminar o roteamento, depois verifico o resultado com a revisão da placa.

Thought for a moment

A tentativa de remover/desativar os pads internos de montagem dos footprints U3/U4 não foi aceita pelo editor de layout; eles ainda aparecem como sobreposição interna do footprint. Vou seguir com a guarda como rota/área indicada em VCM e validar o que a ferramenta consegue aplicar sem alterar o AFE.

Thought for a moment

Executei o roteamento disponível e atualizei as notas em Layout Placement Notes — Analog NH3 Loop Transmitter. A rede VCM_1V25 foi incluída no roteamento global, mas a ferramenta disponível não garante uma geometria de anel de guarda manual ao redor de U2 IN-; deixei a área marcada no silk para inspeção/ajuste manual.

Também tentei corrigir os alertas de EP dos op-amps, mas o editor não aceitou a remoção/edição dos pads internos do footprint; esses alertas ainda precisam ser resolvidos por edição/substituição de footprint antes de fabricação.
