What it is

The Esec E142 is a strip mapping option for Esec die bonders. The strip mapping system is available on the Esec 2100 platform, including the Esec 2100 FC hS flip chip bonder and the Esec 2100 SC die bonder. The Esec E142 enables the bonder to recognize and align to strip positions for accurate die placement.[1]
