Compression Mount Spring Pin Sockets

High Performance Standard Footprint Sockets for 0.30 + pitch devices. Industry Standard Spring Pins in standardized footprint configuration

Technical Documents


Ironwood Electronics spring pin sockets are designed in standardized stepped footprint configurations incorporating industry standard high performance spring pins. Ironwood can design a socket to work with any type IC packages; BGA- LGA - QFN- DFN and even leaded devices where you have minimal space to fit a socket in place of your device to allow fast, easy testing and development.


Features and Benefits

 

Industry Standard Spring Pins Ironwood Electronics has partnered with several Spring Pin manufactures so we can provide designs based on mechanical and electrical requirements, and cost points.
Lid Options The ½ turn Lid is typically used for manual easy testing when higher insertions are needed. Simple bolt down LID is also available and Custom Heat Sink Lids can be designed for special applications.
Excellent signal performance Depending on the electrical performance needed, the Ironwood Spring Pin sockets can be designed using the best type pin required for your electrical requirements.

 

METHODOLOGY

Compression Mount Spring Pin Sockets - methodology ½ Turn LID / Press – Knob turns 180 degrees – latches and press moves down to insert the device to the test position

Frame – secures the contact set to the Test Board and attaches the LID

Contact Set – housing with spring pins

 

Spring Pins we have designed into our sockets Manufacture Relative cost Pin Length @ Test Height (mm)
ECT – Z0 “ Zip pin” $$$$ 1.5
ECT – Z “ Zip Pin $$$ 2.7
Kita – Standard Pitch $$ 2.7-2.8
Other S-SSSS
The above list is Spring Pins we have designed into our sockets- any spring pin you are familiar with can also be designed into an Ironwood compression mount socket
