Precautions for using thermal conductive silver glue and LED conductive thermal conductive silver glue

Since the requirements for solid crystal are extremely high when encapsulating single-electrode chips, the use of conductive glue and conductive silver glue in the solid crystal process is also extremely strict. Although no problems can be seen in the production process, abnormal conditions such as dead lights may occur during user use. Therefore, the performance of solid crystal conductive glue and conductive silver glue will directly affect the performance of LED products and cannot be ignored.

UNINWELL is the manufacturer with the most complete conductive silver glue product line in the world. Its conductive silver glue has excellent performance, good conductivity, strong shear force, good rheology, and low moisture absorption. It is suitable for packaging and bonding of various electronic components and components such as LED, high-power LED, LED digital tube, LCD, TR, IC, COB, PCBA, dot matrix block, display screen, crystal oscillator, resonator, solar cell, photovoltaic cell, buzzer, ceramic capacitor, semiconductor discrete device, etc. The application scope covers electronic components, electronic components, circuit board assembly, display and lighting industry, communication, automotive electronics, smart card/RFID and other fields.

UNINWELL International, based on its own experience in producing conductive silver glue and the usage practices of peer customers, summarizes the matters that need to be paid attention to during the use of solid crystal conductive glue and conductive silver glue as follows, for reference by enthusiasts and friends who produce LEDs:
1. The manufacturer's conductive silver glue needs to be frozen during transportation, and the conductive silver glue should be wrapped with a large number of ice bags or dry ice;
2. Even if the weather is cold, customers should immediately transfer the newly received conductive silver glue into the freezer of a refrigerator at 0-5 degrees for storage;
3. Before use, the conductive silver glue is thawed and used for 1-3 hours (depending on the different conductive silver glues);
4. During use, add an appropriate amount of conductive silver glue in about 2-3 hours. It is recommended to clean the silver glue on the solder drum of the solid crystal machine every 12 hours;
5. When the conductive silver glue shows wire drawing, it must be replaced no matter how long it has been used;
6. After the conductive silver glue reaches the specified point, solid crystal must be performed within 2 minutes;
7. When stopping solid crystal, make sure that the solder drum keeps rotating. If the tin drum containing the conductive silver glue stops rotating for more than 30 minutes, it is recommended to clean the glue drum and replace the conductive silver glue;
8. Put the material into the oven within one hour after crystal bonding, and the longest time should not exceed 2 hours.
