2、 Technical indicators
Epoxy conductive adhesiveSome important technical indicators are important criteria for measuring its performance and applicability. Here are some common technical indicators:
1. Maximum DC volume resistivity: 0.002 ohm cm. The smaller this value, the better the conductivity.
2. Minimum overlapping shear strength: 1400 Psi (9.66 MPa). The larger this value, the higher the adhesive strength.
3. Temperature range for use: -55 ℃ to 125 ℃. Within this range, the conductive adhesive can work normally and will not be affected by temperature.
4. High temperature curing time (116 ℃): 0.25 hours. The curing time of conductive adhesive at high temperature, a smaller value indicates a faster curing speed.
5. Curing time: 24 hours. The time required for the conductive adhesive to fully cure.
6. Operation time: 0.5 hours. The effective usage time refers to the operating time after the uniform mixing of conductive adhesive.
7. Coating area: 156 cm2/g. The coating area per gram of conductive adhesive, the larger the value, the wider the coating area.
3、 Instructions for use
In order to better utilize epoxy conductive adhesive, the following are some usage instructions:
1. Conductive adhesive is a very dilute liquid, so the adhesive and curing agent are easily mixed and can be cured at room temperature.
After mixing evenly, the conductive adhesive has good fluidity and can be coated with a scraper or used by suction needle or screen printing methods.
Before bonding, the surface to be bonded must be cleaned thoroughly to ensure the bonding effect.
For conductive adhesives weighing less than 10 grams, simply remove the prepared two component barriers and mix them evenly before use.
For conductive adhesives weighing less than 85 grams, mix them evenly in a weight ratio of 100:6.3 before use.
in summary,
Epoxy conductive adhesiveIt has a wide range of applications in metal bonding, circuit repair, ceramic bonding, wireless component bonding, and other fields. By understanding its application scenarios and technical specifications, and using it correctly, the excellent performance of epoxy conductive adhesive can be ensured to be maximized. Epoxy conductive adhesive will continue to play an important role in advancing technology, whether in the fields of aerospace, microwave, radar, computer, or automotive electronics.
