Base Material is the first field you set on the Seeed Fusion order page. It shapes how your board handles heat, mechanical structure, bending, and high-frequency signals<\/strong> \u2014 and it determines the layer counts, thicknesses, surface finishes, and processes available later.<\/p>\n\n\n\n

The most reliable way to choose is to start from your product. Confirm four things first: its operating temperature and power, how tight the internal space is, whether the board needs to bend, and how high its signal frequency runs.<\/p>\n\n\n\n

Seeed Fusion offers six base materials. Use the table below for a first pass<\/strong> \u2014 locate the type that matches your core need, then read that section for how to choose.<\/p>\n\n\n\n
