Adesão, abrasão, durabilidade química, UV e intempéries de marcas de laser

Durability depends on mark construction and exposure sequence. Separate bulk-formed contrast from coatings, printed layers, activated or plated features, then test adhesion only where an interface exists and track optical, geometric, surface, mechanical, and functional retention after controlled abrasion, chemical, UV, and weathering exposures.

Dados a serem compartilhados com o fornecedor antes da avaliação do enchimento térmico hBN

O Hexagonal Boron Nitride (hBN) é o principal material de triagem. Para avaliação de amostra de enchimento condutor de calor e revisão prática do formulário RFQ, comparar nomes de produtos ou valores representativos de fornecedores por si só não é suficiente. Primeiro, as funções exigidas da peça ou película final, a aparência aceitável, o intervalo de processamento e as condições reais de ensaio devem ser definidas. Em seguida, os materiais candidatos devem ser comparados sob o mesmo material de base, espessura, processo e condições de pré-condicionamento para obter conclusões significativas.

ESD Por que usar apenas resistência superficial em especificações de plástico não é suficiente

Multi-Walled Carbon Nanotubes (MWCNT), Single-Walled Carbon Nanotubes (SWCNT), Graphene Nanoplatelets (GNP) e Antimony Tin Oxide (ATO) são candidatos à avaliação. Na revisão prática da redação das especificações ESD para bandejas, recipientes, filmes e invólucros, comparar nomes de produtos ou valores representativos de fornecedores por si só não é suficiente. Primeiro, as funções exigidas da peça ou película final, a aparência aceitável, o intervalo de processamento e as condições reais de ensaio devem ser definidas. Em seguida, os materiais candidatos devem ser comparados sob o mesmo material de base, espessura, processo e condições de pré-condicionamento para obter conclusões significativas.
