Bonding glue COB bonding glue IC bonding glue black glue surface sealing glue cold glue

.3 Adhesive used for exposed integrated circuit chip () packaging, commonly known as: black glue or B () bonding glue.
. Classification
. There are hot glue, cold glue, bright glue, matt glue, high glue and low glue

The difference between hot and cold glue is that hot glue is When sealing, it needs to be preheated to a certain temperature. Cold glue does not need to be preheated when sealing, and it can be used at room temperature. However, hot glue is better than cold glue in terms of performance and cured appearance. You can choose it according to your product

.

The difference between glossy glue and matt glue is whether the appearance after curing is bright
or matt.

.: The difference between high glue and low glue lies in the stacking height of the glue during encapsulation. If there are any requirements for the height of the glue after curing, please consider it when purchasing.
. . Performance and use:
< Cold glue is a single-component epoxy resin glue, mainly used for packaging of etc. It is necessary to add diluent when using it. It still has high thixotropy at room temperature. After hardening, the surface is well formed and bright and black. It has excellent bonding strength, electrical properties and moisture resistance. It has excellent properties for Hebang aluminum wires. Protective. Suitable for the protection and fixation of game consoles, calculators, electronic watches, music cards, electronic toys, etc.

. 4. How to use:
Take the glue out of the refrigerator and let it balance with the outside world at room temperature for ~ hours. Diluent needs to be added when dispensing the glue, or it can be used directly without dilution. Adding diluent depends on the height of the sealing glue. The range should be controlled within ~ stir evenly before dripping glue, and then put it into the oven to bake at ~ ℃ for 1 minute to solidify. The oven temperature should not be too low or too high. Glue dispensing tools can be used such as oil pots, glue dispensing machines, brushes, etc. After use, the lid should be closed in time and returned to the refrigerator for storage.
