Today the use of press-in connectors encompasses all fields of electrical and electronical applications. Pressing of electrical components, mainly connectors, is characterised through the matching of the connector pin and the plated through hole of the pcb. Whereas the desired electrical characteristics can be attained relatively independant from the design of the press-in zone, the mechanical characteristics of the press-in zone are crucial for the reliable assembly of connectors where pcb's have different surfaces. Press-in technology Although the scope of requirements at the press-in process is generally defined in time-tested specifications, the novel press-in zones should offer an optimal handling and a reliable termination. Essentially, this is guaranteed through the design of the press-in zone and the meticulous observance of tolerances. HARTING has been using FEM simulations for the calculation and optimisation of press-in zones for a long period of time. This expertise allows us to simulate various pcb configurations very accurate. Due to variety of different connector contact designs, the press-in zone has been designed to fit perfectly to the contact metal thickness and the plated through hole dimensions and tolerances. The patented contact design allows 20 % more tolerance on the plated through hole of 0.6 mm than the standard tolerance +0.07 of 0.6 -0.05 mm. D-Sub The terminating spoon shape of the contact provides a reliable vertical position of the connector for better alignment during insertion. SEK 20 . 02 The renowned needle eye allows for compensation of tolerances of pcb surface properties. The excessive material is displaced within the plated through hole whereby a gastight connection is assured. Board with press-in connectors Competence in press-in technology Due to the high deformation resistance and resilience of contacts, they can be easily and repeatedly removed in case of repairs without impairment to their functioning. Today tinned surfaces are widely used as a standard, the pcb technology trends are moving to low tin or tin free surfaces. Cu, Pd, Au and Ag are the important alternatives. Specific parameters and particularly different friction factors of these surfaces make high demands on press-in zones. chem. Sn pure Cu Pd is extremely versatile and offers a reliable electrical contact, therefore it is especially well suited for applications with these surfaces. Au Ag Please contact us for detailed test reports. Benefits of the press-in technology l Thermal shocks associated with the soldering process and the risk of the board malfunction are avoided.
