Haverhill, MA — DKN Research has introduced thin and light connection devices for fine flexible circuits. The

new UTF Connector FTF Series was developed for small pitch connections between high density flexible circuits.
It provides a wider range of design flexibilities for packaging and termi- nation in portable electronic prod- ucts.
The growing demand for smaller
and more powerful portable electron- ics has fueled the evolution for these products. DKN Research teamed up with Hirai Seimitsu Kogyo, a special- ty component manufacturer in Osaka Japan, and co-developed a new con- nection device using that company’s special chemical etching technologies. The UTF Connector FTF Series will now allow fine pitch connections be- tween high density flexible circuits. The basic mechanism from the FTF Series was created by upgrading the design concept of the current UTF Connectors that were developed for connections between flex circuits and rigid circuit boards. The micro-sized bump array

generates a uniform pressure for the contact pad array between two flexi- ble circuits facing each other, and al- lows electrical connections between the pads formed on the flexible cir- cuits. The connection pitch can be below 0.5mm, and the total thickness of the connection can be less than 1.0mm. The small weight of the con- nectors means that no additional de- vices are required to fix them. In ad- dition, the connectors are not too heavy for the fragile thin flexible cir- cuits. The connections can be com- pleted with simple alignment tools; no special expensive application ma- chines are required. The FTF Series can be used in a

connection purposes. The unique etching process assures the design variations are easy to produce at a very low cost. This is extremely ad- vantageous for customers interested in trial and error processes. The new connectors are custom-
made based on customer require- ments. The chemical etching process allows a broad range of capabilities, from prototype to volume production. This flexibility is possible because the process does not need expensive molding or punching dies. The cus- tomers are able to change the circuit designs in a short time without big
tooling costs. Contact: DKN Research LLC,

tile feedback, the IM series comple- ments and extends the “I” range of sealed pushbutton switches. It is es- pecially suitable for harsh, noisy en- vironments, including those involv- ing vibration, where the use of a sealed switch with a confirming “click” is imperative. Optionally available with a reduced bezel, the IM series fits into the tightest spaces. The switches are excellent for agri- culture, military vehicles, and crane remote controls markets.
