THE BUTTON CONTACT
The unique construction of the CIN::APSE contact
provides superior mechanical and electrical performance.
It is constructed of randomly wound molybdenum wire that
is formed into a cyclindrical shape. Standard CIN::APSE
contact diameters are 0.020" and 0.040".
Mechanical
•
•
•
•
•
•
Small form factor (0.020" diameter by 0.32" min. high)
Low compression force (approx. 2.5 oz. min. per contact)
Multiple beam structures
Several points of contact per button
Extremely lightweight
Natural wiping action
Typical CIN::APSE Applications
• LGA package I/O to PC board (IC packages,
multi-chip modules)
• PC board to PC board (parallel processors,
enhancement/mezzanine cards)
• Flex circuit to PC board (rigid flex, harnessing)
• Flex circuit to ceramic (chip to harness)
Electrical
• Short signal path
• Very low inductance and resistance
• Signal integrity tested in the GHz range
CIN::APSE APPLIED
The basic button contact
configuration consists of a single
button installed in our patented
“hourglass” design.
The hourglass cavity retains the
CIN::APSE contact securely.
Typically 0.003" protrudes from the
top and the bottom of the insulator.
Step 1:
Using alignment features,
position the CIN::APSE
connector between a LGA chip
package and PCB or two PCBs
that have matching footprints.
Step 2:
Add Z-Axis compression
and secure.

TYPICAL CONFIGURATION
1. Button-Only
This is the basic CIN::APSE contact configuration. It is ideally suited for
z-axis applications requiring minimum height, high density, and signal
integrity. This configuration is used in LGA and IC sockets, PCB to PCB,
and flex print circuit to PCB applications.
2. Plunger-Button
The addition of a gold-plated brass plunger increases the durability of the
CIN::APSE contact system while also achieving additional height. This
configuration suits itself especially well for PCB to PCB interconnect and
those that require excessive handling.
Other custom configurations are
available. Contact Cinch for details.
CIN::APSE Applications
Due to its breakthrough nature, it is impossible to illustrate all of the applications CIN::APSE
technology can address. The following applications illustrate only a portion of the types of
interconnect problems that CIN::APSE can solve.
