In the electronics industry, workpieces are often exposed to extreme stresses, particularly during manufacturing and handling processes. Mechanical or thermal stress is not the only cause of damage to components or materials.
Electrostatic charges and the resulting uncontrolled electrostatic discharge (ESD) produce irreversible damage to electrical, electronic, or optoelectronic components such as IC chips or printed-circuit boards.
Experienced system consultants will help you design the vacuum solution to suit your industry-specific needs.

An uncontrolled and rapid equalization of potentials results in a high electrical voltage and causes irreparable faults on assembled circuit boards and their sensitive components.
A specific resistance must be ensured in order to protect parts and components – particularly in handling applications and in the case of direct workpiece contact.
The ESD material from Schmalz features a dissipative resistance with a value of 106 to 109 Ω, which ensures controlled and damage-free dissipation of the voltages applied to the workpiece.
The “point-to-ground” measurement is one particular means of verifying discharge capacity while taking the specific resistance into account. Based on this measurement, it is possible to identify the range in which the resistance of the overall system lies. With the aid of special resistance meters, the discharge resistance between a measuring point (1) and a grounding point of the system (ground potential) (2) can be established.
The ESD capability of the overall system is supported by the specific resistance of the NBR-ESD suction pads. Their use in conjunction with conductive spring plungers and the grounded system creates an ESD-capable connection.
Schmalz offers a wide range of suction cups with this specific resistance. These include suction pads of the FSG, FSGA, PFYN, and SGON series, among others.
Together with the conductive spring plunger FSTIm-CO, Schmalz offers a combined solution that can be utilized in a suction spider (SSP) with robot connection.
By means of practical test procedures, which are devised in-house, Schmalz ensures that resistance values are met regardless of the suction cup geometry and size.

The NBR-ESD suction cup material from Schmalz features a resistance value of 100 kΩ to 1 GΩ and thus satisfies the specific ESD requirements.
