Integrating Nitinol "TiNiMIGHT Technology"
San Diego, CA. - - Autosplice has become a leading innovator in the design and assembly of "TiNiMIGHT" applications using nickel titanium (nitinol) materials that can be effectively used as simple, low-mass, low-power, low-cost alternatives to larger and more costly conventional solenoid, actuator, motor, relay, and/or switch assemblies.
Nitinol is a family of intermetallic materials that contain a nearly equal mixture of nickel and titanium, with other elements often added to adjust or "tune" the material properties. Nitinol exhibits a combination of unique characteristics including "Shape Memory" and "Superelasticity" that enable nitinol assemblies to flex like muscles when electrically driven, dynamically changing their internal structure at certain temperatures and then returning to their original shape when the current flow is ceased.
By building upon a strong history in the automation of both insertion and splicing technologies, Autosplice has quickly moved to the forefront when it comes to attaching nitinol muscle wire to PCB assemblies or other structures. For example, to create TiNiMIGHT assemblies for applications such as micro-latches for opening secure medical dispensing cabinets, Autosplice developed an automated process whereby clip-on tabs are spliced to the TiNiMIGHT wire, which is then attached directly to pins that have been inserted into the PCB using Autosplice automation technologies. The integrated process provides a simple and automation-friendly electro-mechanical interconnection that consistently holds the TiNiMIGHT wire in the desired position and simultaneously provides the electrical connection needed to drive its operation.
Autosplice also has developed variations on the basic process that allow for splicing the clip-on tabs at specified positions along an entire reel of TiNiMIGHT wire and then re-reeling it for subsequent trimming and attachment during a final assembly process. Additional process alternatives can include pre-molding plastic housings around the clip-on terminals to create complete self-contained slip-on TiNiMIGHT actuator assemblies.
Because of its light-weight, low-cost and simplicity, nitinol TiNiMIGHT wire is rapidly gaining attention as a cost-effective alternative to other physical triggering devices such as solenoids that require more space, power and design complexity. TiNiMIGHT wire has significant advantages for creating miniaturized assemblies because the Autosplice method allows the actuator wire to be attached directly to a PCB with a minimal use of PCB real estate. In addition to the initial uses for implementing electronically triggered micro-latches in medical assemblies, nitinol TiNiMIGHT wire offers opportunities for reducing the size and cost of many solenoid applications in the automotive industry, such as opening vents or triggering latches. The low-power advantages of TiNiMIGHT wire also make it a good candidate for implementing physical triggering mechanisms in products where battery life is a critical factor, such as toys or other portable devices.
