The four major impacts that may occur after the curing of potting adhesive (adhesive) are unevenness

which may affect its performance. Let’s take a look at the causes and possible impacts of the problem: Reason: 1. Construction environment temperature: When the construction environment temperature is too high, the sealing adhesive (adhesive) liquid may start to solidify during the flow process, resulting in uneven surface after curing.
2. Impurity residue: If there are impurities residue on the surface of construction equipment, substrate, etc., the sealing adhesive (adhesive) liquid may become uneven after curing.
Impact: 1. Reduced performance of potting adhesive: Uneven cured surfaces may lead to a decrease in the waterproof and moisture-proof properties of potting adhesive. Thin areas may be more susceptible to moisture intrusion, which can affect their protective effect.
2. Component detection problem: If the sealing adhesive (adhesive) liquid is thick in certain positions after curing, it may make it difficult to detect or repair components in these positions, increasing the difficulty of maintenance.
3. Stability issues with potting adhesive: Uneven cured surfaces may cause slight tilting of electronic components during operation, which may affect the stability and performance of the equipment.
4. Increased risk of sealing adhesive failure: Under long-term use, electronic components in certain positions may increase the risk of failure due to uneven adhesive thickness.
To avoid these issues, attention should be paid to maintaining an appropriate construction environment temperature during the application of sealing adhesive (adhesive), ensuring that construction equipment is clean and free of impurities, and ensuring that the surface of the substrate is free of oil and dust. This can reduce the possibility of unevenness after curing, thereby maintaining the performance and reliability of the sealing adhesive.
