Production is scalable from a single piece all the way to full OEM production quantities.
Supported mating pad types include PGA, BGA, LGA, CGA and custom packaging. Most
customers today utilize the Center-to-Center Contact Pitch of 1mm. The 1mm pitch is
often regarded by customers as the perfect balance between pad/array size optimization
and cost containment, while still offering excellent signal isolation and prevention of
crosstalk. But, when the application requires a differing approach, we do offer a full line of
possible mating pitches including .4mm, .5mm, .65mm, .8mm, 1mm, 1.27mm plus many
custom pitches. And with I/O counts as high as 5000, we have an interconnect solution for
any fine pitch / high density requirement imaginable.
While most applications require just a single use permanent mounting connection, Fuzz
Button® Interposers and Connectors can actually be reutilized many hundreds or
sometimes even thousands of times. This flexibility is ideal to allow for interconnect
and/or device repurposing or in the event of a device failure. And with the inclusion of
Hardhats into the stackup, mating cycles up to 500,000 are achievable with no significant
signal degradation.
A wide array of high quality interconnect body/carrier materials are available to choose
from, including Ultem®, Teflon®, PEEK®, Torlon®, FR4, G10, Formex®, Rogers,
Aluminum and Brass,as well as any other commercially available dielectric plastic or
metal you may prefer.
For interconnects that need to go airborne, stay terrestrial or even go underground,
Fuzz Button® technology delivers the reliability you need!
