Process review
Check the complete material system, not one number.
Qualification should cover green-sheet condition, printing, via filling, drying, lamination, firing, dimensional compensation and final electrical performance.
- Confirm usable size and fired dimensions
- Confirm conductor and via-paste compatibility
- Run prototype and lot-to-lot verification
- Not represented as a drop-in replacement
FAQ
Questions before qualification
Are the website values guaranteed?
No. They are representative preliminary-selection values. Guaranteed values require a current controlled specification.
Can this grade replace an existing material directly?
A replacement evaluation is required for firing, shrinkage, conductor compatibility, dimensions and finished performance.
What should be sent for a sample review?
Send the target size, thickness, firing profile, frequency, dielectric/loss targets, shrinkage tolerance, conductor and prototype quantity.
