How to use the result
Change the inputs to compare a design scenario. The result is a starting point for discussion and does not replace a package escape study, a field solver, a qualified fabrication process or a supplier quotation.
Method and assumptions
The selector maps application, loss priority and thermal exposure to a material family. It does not compare live stock, approve a substitute or calculate impedance. Use exact material grades, construction-specific properties and a factory-approved press system.
What to confirm next
- The package pin map, actual land pattern and usable routing channels.
- Exact copper, pressed dielectric, via spans and material system.
- Electrical targets, assembly exposure and acceptance requirements.
Send an inquiry with your assumptions and the decisions still open.
