Midas DeLidder System
Non-destructive lid removal for hermetic microelectronic packages
Precision
±0.001"
Process Type
Dry Mechanical
Package Types
Rectangular & Round
Product Overview
The Midas DeLidder is a mechanically-driven lid removal system engineered for precision rework of hermetically sealed microelectronic packages. It mills through lid flanges without contaminating or damaging the internal cavity, leaving a resealable surface suitable for high-reliability applications. Designed for cleanroom environments, the DeLidder has been the industry standard for over 30 years.
Key Features
Precision-controlled Cutting
Precise control over depth and width of cut ensures consistent results without damaging internal components.
Depth Control
