◇◇ FAQ ◇◇


1. What is AMB ceramic substrate etching factor ?

The etching factor is a critical parameter that measures the precision and quality of the etching process, particularly in patterned substrates like those used in electronics. (e.g., PCB, AMB/LTCC/HTCC ceramics).


2. How to calculate AMB ceramic substrate etching factor ?

Definition: The etching factor quantifies the ratio of the depth of the etched feature (e.g., a trench or via) to the undercut (lateral etching).

It reflects how well the etching process maintains vertical sidewalls and avoids excessive sideways erosion.

Etching Factor=Undercut (u) / Depth of Etch (h)


3. Why does the etching factor matters in Ceramic Substrates ?

Performance Requirements

Poor etching factors can cause short circuits, impedance mismatches, or weak interconnects.

Design Impact

A low etching factor may force designers to increase feature spacing, limiting miniaturization.
