An advantage of this design is the accessibility of the board from above when clamped. Nevertheless, protection against accidental contact is also possible if this is necessary due to high voltages, for example.
In this case, a connector on the circuit board had to be contacted with a very fine pitch. This was not possible with test needles. Therefore, a circuit board with the matching mating connector was designed.
In this example, a very thin circuit board with many needles had to be contacted. At the same time, an electromagnet had to be positioned directly above it when clamped, which made it difficult to hold it down from above. A mushroom-shaped geometry pops through a hole in the board and spreads out before the pins make contact. in order to also hold down the board in the middle. This is a good example of a combination of high-precision parts made using the Material Jetting (MJP) process and more flexible parts made using Selective Laser Sintering (SLS).
