SURLON GROUP / INDUSTRIES / SEMICONDUCTOR
BUILT FOR THE TEST FLOOR. MACHINED FOR THE FAB.
A test socket and a wafer chuck ask for opposite things — an ESD safe polymer held dead-flat in a clean room, and a metal fitting machined to microns. Surlon Group supplies both — Surlon India’s engineering polymers and Surlon Precision Solutions’ aerospace grade machining — from one integrated group.

ONE SEMICONDUCTOR SUPPLY CHAIN
TWO SURLON GROUP COMPANIES. ONE CHIP, ONE FAB.
A test socket and a wafer chuck ask for opposite things — an ESD-safe polymer machined dead-square in a clean room, and a stainless or brass fitting held to microns. Surlon Group builds both in-house, so semiconductor OEMs and fabs source a full tooling set from one group.

MATERIALS FOR BACK-END TEST & FIXTURING
5 grades
The miniaturization of IC devices is pushing back-end test to the limits of polymeric materials — thinner cross sections that still need to hold their shape. Surlon India answers with Polytuff®, Metalon®, MetaPOM® and Metron® ESD-safe grades, machined in a temperature-controlled, clean-room environment up to 5-axis, for test sockets, vacuum chambers and wet-process tooling.
POLYTUFF® (PPH)
- Purpose-built for semiconductor & electronics
- Free from porosity, center-line defects & contamination
- Each plate annealed for lower stress
METALON® (PA-ESD)
- Cast polyamide modified for harsh environments
- Meets semiconductor purity requirements
- Plates & rods in various sizes, easily machined
METAPOM® (POM-ESD)
- High dimensional stability — ideal for fixtures & test jigs
- Superior stiffness with very low moisture absorption
- Easy to machine to precision tolerances
METRON (PEEK-ESD)
- Higher-temperature, precision-part grade
- Very low CLTE over a wide temperature range
- Rigid, moisture & chemical
resistant
METRON (PAI)
- Optimized for vacuum chamber applications
- Low erosion in plasma chambers, low outgassing
- Excellent low ionic content for demanding chambers
TEST SOCKET TRENDS
Why it matters
As IC devices shrink, cross sections thin out and require stiffer materials to survive test conditions — the challenge is enhancing stiffness while preserving machinability of ever – smaller hole size and pitch.
Higher I/O count
Smaller hole & pitch sizes
Thinner cross sections
CRITICAL PROPERTIES
FLEXURAL MODULUS
Manages the robustness of the finished socket under test conditions.
MELTING POINT
Critical for clean through-holes during drilling.
TENSILE ELONGATION
Controls the accuracy of holes
during machining.
CLTE
Dimensional stability over a
varied temperature range in
use.
MOISTURE ABSORPTION
Critical for maintaining
dimensional stability.
VACUUM CHAMBER SOLUTIONS
KEY CONSIDERATIONS
- Increasing energy in plasma chambers
- More aggressive plasma chemistries, oxygen exposure
- Material selection tuned per application for cost vs. performance
- Replacing polyimide for reduced cost & higher performance
- Careful use of ceramics & quartz — cost & breakage risk
- Higher ionic-purity requirements as node size shrinks
TYPICAL APPLICATIONS
- Screws & pins
- Clamp & trench rings
- Valve housings
- Shower heads
- Various etch & CVD parts
WET PROCESS SOLUTIONS
KEY CONSIDERATIONS
- Corrosion resistance
- Flatness
- Strength & wear
- Purity
- Chemical resistance
- Dimensional strength
TYPICAL APPLICATIONS
- Spin discs & chucks
- Wafer motion gears
- Shower heads
- Wafer grabbers
- Pins & screws
MINIMAL CENTER-LINE POROSITY
Surlon has developed proprietary processing methods to minimize the high stress and center-line porosity common with standard polypropylene. Plates from 2″ to 5″ thickness are manufactured to the highest standards for the semiconductor wet-process industry — delivering an ultra-clean plate that minimizes surface contaminants at lower overall cost.
IN-HOUSE MACHINING ENVIRONMENT
Why it holds tolerance
Every polymer part is machined on-site, not just moulded — the same environment that stabilizes a cast nylon bearing for a wind turbine also holds a test-socket bore to spec.
