Robust connections for commercial vehicle electronics press-fit technology & solutions by miunske
miunske makes electronics safe, powerful, and durable
miunske® focuses on the requirements for innovative electronic components and tailors its product portfolio and PCB assembly to the requirements of the commercial vehicle sector. With reliable and robust press-fit components as well as efficient and forward-looking connection technologies in press-fit technology, miunske meets the requirements for high currents, strong vibrations, and extreme environmental conditions in use. This article answers questions about the press-fit process, highlights its advantages, and provides an overview of the range of products offered by miunske GmbH, from press-fit components to printed circuit board manufacturing using press-fit technology.
What is press-fit technology?
high-level mechanical connections
miunske manufactures robust electrical assemblies and printed circuit boards using press-fit technology in its in-house production facility. In addition to THT and SMT assembly, the press-fit process is one of the most reliable methods of PCB assembly. miunske prefers to use press-fit components from its own production. Using suitable press-fit machines and the appropriate tools, the press-fit components are mechanically applied to the printed circuit board by pressing the specially shaped press-fit pins into the corresponding metallized holes in the printed circuit board.
In detail, the press-fit process works as follows:
- the press-fit pin is elastically deformable
- when pressed into the PCB hole, a gas-tight connection and thus a low-resistance electrical contact is created
- the press-fit connection is reflow and solder-free
Advantages of press-fit technology
Even more robust and individually manufactured electronic components
High reliability
- through gas-tight, vibration-resistant contacting
- low contact resistances
- high resistance to thermal and mechanical stress
Avoiding thermal stress
- no soldering errors, no cold solder joints
- protection of temperature-sensitive components
- minimal risk of failure
process advantages
- compact positioning of components and double-sided assembly of the circuit board are possible
- avoiding testing and reworking steps
- process flows completely in miunske’s control thanks to in-house production
- continuous optimization and process monitoring ensure high quality of the end product.
sustainability
- sustainable thanks to the elimination of solder and flux
High Quality
- assembly inspection by AOI
- stress tests in the in-house high-current laboratory
- functional testing based on set parameters and requirement profiles
