Thread tolerance: Nominal diameter <M1,4 -> Tolerances 5H; >M1,6 -> Tolerances 6H
In general, the tolerance class DIN ISO 2768-mk applies to fasteners.
fasteners are used on PCBs as a cost-effective mounting option or as a simple spacer. Furthermore they can also be used to conduct electrical signals, for ground connection or for thermal management. Because fasteners are designed for fully automated production, manufacturing processes can be significantly optimized due to simple and fast assembly.
The components can be removed directly from the reel, then assembled and fixed in the reflow soldering process. The standard tin-plating ensures excellent solderability, but other coatings can be chosen as an alternative. If a high corrosion protection is necessary, e.g. a gold-plating is used. fasteners are delivered with a brass alloy as base material.
To enable a simple Pick&Place process, fasteners are provided with a release liner. This tape is used as a suction point for the nozzle and can be easily removed after assembly.
fasteners are available with the following options:
MTC offers the possibility to design and construct suitable components together with the customer. The tool-free production of our fasteners offers a wide range of different design possibilities and dimensions.
