BIZON® Press-Fit Technology
Smart, high-performance and reliable connection solution.
Construction-related freedom, free material selection, adaptable
ALACsystems offers an innovative solder-free connection technology with BIZON® press-fit technology for the requirements of the automotive supply industry and industrial electronics. The press-fit techniques are a solder-free electromechanical connecting method, with which elastic workable or solid pins are pressed into metal coated circuit board holes with the aid of a pressing tool. At the points of contact between the pressing area of the pins and to the metal coated hole in the wall, a permanent gas-tight connection is therefore formed.
High current-carrying capacity
The important characteristic here is that the diagonal of the pin cross-section is greater than the diameter of the copper sleeve in the circuit board. The BIZON® Contact, as an elastic contact, offers the greatest possible cross-section in a circuit board hole with overriding contact characteristics. As a result, it is possible to handle several hundred ampere ranges with standard circuit boards. This has an important price advantage, particularly in the case of motor vehicle applications. The contact can be produced in every size and sheet-metal thickness, with free material selection. A unique feature is that, with the same production enginee-ring, both a non-detachable press contact and a detachable plug contact can be manufactured.

Feasibility analysis, development, manufacturing
In the phase of product development, we specify the significant influence parameters such as basic material, press-in zone geometry and surface coating, and then monitor these in the series. We advise and support our customers right from the beginning throughout the entire project phase. In the test laboratory, significant characteristic values according to DIN EN 60352-5 can be tested and validated. The inspection and measuring equipment required for that is available. Test circuit boards, or on request also your series circuit boards, are used for the test.
