Electronic component protection by potting compounds Pumps for electro casting and the encapsulation of electronic components
Disruptions, loose connections, short circuits caused by liquids? All this does not have to occur …
Without electronic products, practically nothing in our daily lives will function. Billions of circuit boards and assemblies accompany us often without our realizing it. They are in heating systems, washing machines, televisions, wind turbines, automobiles, boats and ships – and they must function smoothly at all times and everywhere.
Temperature fluctuations, condensation, moisture, dust, foreign objects or vibrations must not harm the electronic or electrical components: The functionality of entire products succeeds or fails depending on their functionality.
Electro casting offers effective protection of the sensitive components because this technology will coat the components with a special casting compound – this is where SCHERZINGER pumps come into play.
Precise pumps for a precise dosing
In electro casting, 2-part casting resin is frequently used: The components A (resin) and B (hardener) are supplied from the respective containers and dosed precisely according to the required mix ratio and the specified applied quantity as guided and applied by the 2-part mixer. Once the components are encased in a special casting compound, the material dries. The electronic components are thus securely fixed mechanically, protected from contact, electrically shielded and made vibration-resistant. To apply the casting resin precisely to the nozzles is a task for SCHERZINGER gear pumps.
If the mixture is right, the protection is right
Seals can be damaged, thereby exposing the interior of the casing meant to be protected – in an electro casting, what is to be protected – the components themselves - are, however, completely enclosed; this is, above all, an advantge for small, sensitive components.
So that this protection really holds, the mix ratio of the casting compound must be right. Precise as a heartbeat, the working pumps from SCHERZINGER reliably ensure exactly this:
Observance of the defined resin and hardener ratio
Attainment of the defined output quantity
High operational safety and wear resistance
Bubble-free, low pulsating conveyance and dosing
Variably adjustable motor control – primarily, pump pressure and flow rate
SCHERZINGER gear pumps – simply more safety
Do your customers require the highest operational safety and a conveyance of the casting compound with low pressure fluctuation? Then you are on the side of safety with SCHERZINGER: Thanks to over 40 years of experience and a great deal of ingenuity, our pumps have exactly the product characteristics necessary for this.
