PEEK test socket or IC test fixture creates the precise mechanical interface between a packaged semiconductor device and automated test equipment. The socket body must hold contact-pin locations, device pockets, and datum features through repeated insertion cycles and changing test temperatures.

PEEK Test Socket & IC Test Fixture Manufacturer | Custom CNC Machined PEEK Parts Supplier

Product Introduction

JUTAI manufactures custom CNC machined PEEK test socket components from customer drawings, 3D models, and inspection requirements. PEEK is selected for its dimensional stability, dielectric performance, low moisture absorption, wear resistance, and ability to retain strength at elevated temperature. These properties help reduce pitch drift, burr-related contamination, and premature wear in engineering validation, final test, burn-in, and handler interfaces. Natural, reinforced, and ESD-controlled grades can be evaluated according to hole diameter, wall thickness, temperature range, and electrostatic requirements. For very fine features, our process planning considers tool geometry, staged machining, stress control, and non-contact inspection. JUTAI supplies prototypes, replacement nests, contactor plates, socket bodies, and repeat production for semiconductor equipment builders and test engineering teams.

JUTAI supplies peek test socket / ic test fixture, custom peek test socket / ic test fixture components, and precision CNC machined high-performance plastic parts to drawing. Buyers seeking a peek test socket / ic test fixture manufacturer, custom machining supplier, or engineered PEEK and PEI parts partner can submit CAD files for review.

Key Features

Stable pin-hole position and device-pocket geometry across thermal cycles
Low moisture absorption for more consistent dimensions in controlled test environments
Strong dielectric insulation between contacts and surrounding hardware
Wear resistance for repeated device insertion, socket cleaning, and handler operation
Fine-feature CNC machining for contactor plates, nests, guides, and socket bodies
Optional ESD or reinforced grades for application-specific electrical and mechanical behavior
Low particle-generating material options for semiconductor back-end equipment

Material Selection

Grade selection for an IC contactor starts with pin pitch, socket temperature, electrical isolation, cleaning chemistry, and the allowable movement of thin webs. The following comparison is specific to semiconductor test hardware rather than a general ranking of high-performance polymers.

Material Grade	Engineering Characteristics	Application Fit
PEEK Natural	Unfilled resin preserves strong dielectric behavior, low water uptake, and clean fine-feature machining.	Usually the first candidate for socket bodies, DUT nests, and contactor plates with closely spaced holes.
PEEK CF30	Carbon reinforcement raises modulus, controls creep, and can improve heat transfer, but it changes electrical behavior.	Consider it for rigid mechanical carriers only after conductivity and contact-clearance requirements are reviewed.
PEEK GF30	Glass-filled PEEK reduces thermal movement and increases stiffness under sustained clamping force.	Useful for thicker alignment frames where dimensional restraint matters more than ultra-fine machinability.
ESD PEEK	A controlled dissipative grade allows charge to bleed away without giving up PEEK temperature capability.	Recommended around static-sensitive IC packages when the target surface-resistance range is stated on the drawing.
PEI ULTEM 1000	Amber unfilled PEI provides insulation, inherent flame performance, and visual translucency at moderate test temperatures.	A practical option for inspection fixtures, engineering nests, and lower-temperature socket support pieces.
PEI ULTEM 2300	Thirty-percent glass-filled PEI adds rigidity and better load retention to the ULTEM material family.	Suited to fixture bases and structural holders when glass fiber is acceptable near the device interface.

Manufacturing Capability

Socket manufacture is planned from the critical contact pattern outward. Datums, hole sequence, burr direction, and inspection access are defined before cutting starts.

CNC machining: multi-axis production of device pockets, pin arrays, and handler interfaces
Micro milling: controlled tools for narrow slots, thin lands, counterbores, and local reliefs
Precision turning: concentric retainers, insulating sleeves, round nests, and contact guides
Surface grinding: thickness and parallelism correction for contactor plates that require flat reference faces
Drawing-based production: revision-controlled builds from STEP models, 2D tolerances, and inspection plans

Typical Applications

Automated test equipment (ATE) socket bodies
IC final-test contactor plates and handler nests
Burn-in and reliability-test fixtures
BGA, QFN, LGA, and custom package test interfaces
Probe-card support and alignment components
Semiconductor device characterization fixtures

Technical Advantages

Datum strategies developed for dense pin patterns rather than ordinary plastic plates
Staged roughing and finishing to reduce movement around thin socket walls
Optical or non-contact measurement options for features that are difficult to probe
Material review covering ESD behavior, dielectric separation, and thermal cycling
Prototype sockets can be revised without committing to an injection mold
For semiconductor programs, JUTAI applies 15 years of high-performance-plastics experience and qualified CNC control down to ±0.005 mm on approved features. Victrex PEEK and SABIC ULTEM PEI can be specified alongside PSU or PI when the test profile calls for another polymer family.

FAQ

What is a PEEK test socket or IC test fixture?

It is a precision polymer interface that locates an IC package and supports the contact system during electrical, burn-in, or reliability testing.

Why choose PEEK instead of metal for an IC test socket?

PEEK provides dielectric separation, low moisture absorption, low mass, and stable geometry without the secondary insulating layers normally required by a metal body.

Can JUTAI provide custom machining for PEEK test sockets?

Yes. Socket bodies, contactor plates, nests, pin guides, and replacement fixtures can be made from customer CAD data with critical dimensions identified for inspection.

Should a test socket use natural PEEK or ESD PEEK?

Natural PEEK favors electrical isolation, while ESD PEEK is selected when controlled charge dissipation is required. Pin spacing and the specified resistance range decide the choice.

What information helps JUTAI quote an IC fixture?

Please provide the package outline, contact pitch, operating-temperature window, ESD target, flatness requirement, CAD file, and expected prototype or production quantity.
