Adhesives with Electrical Conductivity for Applications on PCBs

Electrically conductive adhesives are the perfect solution for making electrical contacts on circuit boards and other temperature-sensitive substrates, as their curing temperature lies clearly below soldering temperature. In addition these adhesives are much more flexible than solder and are therefore better able to withstand vibrations. They can also be jet-printed or plotted, allowing the production of much more delicate conductors than can be achieved with soldering. A further advantage over soldering is that conductive adhesives are lead- and solvent-free.

There are two types of electrically conductive adhesives: isotropic and anisotropic. Isotropic conductive adhesives (ICA) are electrically conductive in all directions. They are used in applications such as chip contacting and bonding electrically conductive SMDs.
Anisotropic conductive adhesives (ACA) contain special conductive particles in the µm range, which conduct electricity only in one direction. These adhesives are used, for example, in many sensitive structures on circuit boards, such as LCD connections or for contacting FPC (flexible printed circuits).

With its Elecolit® range Panacol offers a broad spectrum of electrically conductive adhesives: single-component adhesives that can be simply applied with dispensers or jets or screen-printed, as well as two-component products that cure at room temperature and have a long storage life.
