PCB relays can be assembled manually or automatically. The grid as well as the hole diameters are to be carried out according to the specifications in the data sheet. The relays must not be fixed on the PCB by bending the solder terminals. This may change the relay parameters or damage the sealing.

If the relays are to be fixed by means of an adhesive, it must be ensured that they are not damaged by impermissibly high temperatures or the material used. The use of silicone in the vicinity of the relays must be avoided at all costs. Silicone can diffuse through the relay housings and cause contact problems.

In the case of automatic assembly, the permissible acceleration values should be observed. Shock loads, e.g. from dropping, should also be avoided. A hard impact from a height of 0.5 m can cause accelerations of several 100 g, which can cause damage inside the relay (e.g. cracks in plastic parts, reduction of contact forces, the armature jumping out of its bearing). In case of doubt, these relays should not be used any further.
