The invention relates to a method for producing at least one functional region on an electrical contact element such as, for example, a switching contact or a plug type contact. In order to prevent the high environmental burden which is disadvantageous in wet-chemical methods and to overcome the restriction to a very small number of materials caused in hot dip methods in physical technical terms, and to substantially improve the spatial possibility for selection and structuring which is insufficient in both techniques, there is provision according to the invention for at least one material coating to be applied mechanically in a highly selective manner to the contact element in the functional region and subsequently highly energetic thermal radiation such as, for example, a particle beam in the form of an ion and/or electron beam, to be directed onto the at least on material coating.

A method to remove slugs from a circuitry pattern on the fly during the fabrication of a flexible printed circuit, the method includes applying a coverlay reel-to-reel onto one side of the metal foil on the fly and applying a sacrificial liner reel-to-reel onto another side of the metal foil on the fly. Then, after the slugs and circuitry patterns are created from laser ablation, the slug can be removed by applying compressed air to the slugs and/or peeling off the sacrificial liner from the circuitry pattern reel-to-reel.

A method for manufacturing circuit board, including: providing a substrate; printing a first conductive layer on a surface of the substrate, the first conductive layer includes a plurality of electrode units arranged in an M*N array, each of the electrode units includes a first electrode, and a plurality of second electrodes distributed around the first electrode; printing a first insulating layer on a side of the first conductive layer away from the substrate; printing a second conductive layer on a side of the first insulating layer away from the substrate; printing an anti-oxidation layer to cover surfaces of the first conductive layer and the second conductive layer away from the substrate; and printing a second insulating layer to cover regions of the substrate not covered by the first electrode and the second electrode. A circuit board is also provided.

Electrical connector includes a housing, signal contacts, and ground shields. The signal contacts are coupled to the housing and positioned for mating with mating signal contacts of a mating connector. The ground shields are coupled to the housing and at least partially surround the signal contacts to shield the signal contacts. The ground shields are plated with a ground-material composition along one or more contact segments of the ground shields that come into compression engagement with one or more other conductive members. The ground-material composition includes a tin-nickel (Sn/Ni) alloy plating layer. The signal contacts are plated with a signal-material composition that is different than the ground-material composition.

A method of manufacturing includes bonding a paste material to an organic substrate by a polymer thick film (PTF) process to form a PTF trace, coating a sinterable material over the PTF trace, and sintering the sinterable material to the PTF trace.

Applying a solderable surface to conductive ink may include partially curing a conductive ink trace; applying, to the partially cured conductive ink trace, a conductive paste comprising conductive particles; and curing the partially cured conductive ink trace and the conductive paste.

Conductive articles include an electrically insulating substrate with conductive regions on the substrate, the conductive regions are conductive patterns of a transparent conductor and a resist matrix. The substrate also has non-conductive regions, and exposed conductive contacts, where the conductive contacts are in electrical contact with the conductive regions. The non-conductive regions are formed by selective chemical etching of the transparent conductor coating, where the selective etching does not remove the conductive patterns or conductive contact.
