Solderless press-fit joints are highly reliable and safe against external influences such as vibrations, impacts or shocks. Thanks to these advantages, press-fit technology (also: cold welding) is the fastening technology of choice for a number of assembly operations involved in the manufacture of products in the 3C industries – the computer, communication and consumer electronics sectors.
For example: the press-fit method is used to assemble printed circuit boards (PCBs) with power electronics and connectors for circuit boards; it is also used in board-to-board assembly of PCBs (backplanes or back panels). Performing these complex press-fit processes to high standards of quality and efficiency presents a challenge: how can force and positioning be controlled with precision? The same issue arises with display bonding processes to join particularly sensitive materials and components such as glass and touch sensors: here too, it is essential to apply the required press forces with maximum precision and repeat accuracy.
