How to Use
- Pre-Mix Preparation: Thoroughly stir Component A to evenly distribute settled fillers, and shake Component B vigorously to ensure uniformity, avoiding stratification that affects adhesion and resistor network accuracy.
- Precision Mixing: Strictly follow the recommended weight ratio of Component A to B, stirring slowly and evenly to ensure full integration without air bubbles that cause insulation gaps or resistor short circuits.
- Degassing (Optional): After mixing, place the adhesive in a vacuum container at 0.01MPa for 3 minutes to eliminate air bubbles, then carefully pour it onto precision resistor networks to ensure full coverage of resistor elements and solder joints.
- Curing: Place the encapsulated resistor networks at room temperature or heat to accelerate curing; enter the next process after basic curing, and ensure 24 hours of full curing. Note: Environment temperature and humidity significantly affect curing speed and resistor stability.
