- Custom Footprints & Mounting to Existing Devices
- Double Sided Test
- Multiple Lid Styles Available
- Very Low Profile Lids for Micro Probing
- Multiple Types of Pogo Pins are Available to meet most requirements (Lead-free, low inductance, high force, high current, Kelvin testing, etc.)
- Open Socket Bases for back-side emission
- Low-inductance pins for RF characterization and test
- High force pins for lead free packages
- Pockets under sockets for component placements
- Dual side testing
- Interfaces to Handlers
- Multi-Site Socket
Examples of Custom Applications
Custom Floating Base Socket on Customer PCB
This socket includes milled areas in the backing plate and socket body to accommodate existing circuitry while pogo pins contact the pads on the PCB.
Custom Socket and Milling
This socket includes milled areas in socket body to accommodate existing circuitry while pogo pins contact the pads on the PCB. The custom footprint matches existing holes in customer's device.
Partially Populated / Partially open Clip on Lid
This socket and lid combination allow access to a portion of the UUT which has unique ground pin placement and a partially populated region.
Module Test Sockets
This module test socket has regions milled out for on board components and incorporates a daughter card, allowing the socket to mount to a universal fixture base.
Custom Sized Socket
Shown here in comparison to a US dime, some solutions can allow for very small footprints.
Multiple Site Test Sockets
Three Site Leadless Test Socket
Multi-Site test sockets may be available for small packages of any type. A single socket can be designed with multiple pocket sizes, allowing a single socket to test multiple packages. Multi-site sockets may limit available lid styles, recommended for FA use.
Heat sinked lids
Copper Heat sink on Adjustable Clip on Lid
For large BGA devices requiring high heat dissipation. Fan produces over 20cfm and is powered by a standard MOLEX connector. The large clips allow for fast and easy package exchange. The large knob allows for precise pressure adjustment of the heat sink surface to package surface.
