Micro-potting application case: How to achieve uniform and precise adhesive coating of sealing resin on connectors?

 Achieving uniform and precise adhesive coating of sealing resin on connectors requires high-precision dispensing technology, equipment selection, and process optimization. This, combined with the connector’s structural characteristics and sealing requirements, necessitates breakthroughs in core technologies and system collaboration to achieve precise control of adhesive quantity and consistent coating. The following details the implementation path from four dimensions: technical solutions, core equipment, process optimization, and application effects:

Core Technology Support: Precise Control of Adhesive Uniformity and Stability



● Non-Contact Spray Dispensing Technology

 

a.Technical Principle:Using Piezoelectric Injection glue dispensing valve or Pneumatic injection glue dispensing valve, the adhesive is atomized or quantitatively sprayed onto the connector surface under high pressure, eliminating contact with the workpiece and avoiding scratches to precision connector components. Piezoelectric spray valves can achieve high-frequency spraying of 300 dots/second, suitable for medium to high viscosity sealing resins, and particularly suitable for scenarios with small connector pin pitch and sensitive surfaces.
