Red glue is a kind of thin poly compound, belonging to the SMT materialwith viscosity, liquidity, temperature property, wetting property.Production, red glue with the objective is to make the parts firmlyadhered to the PCB surface, prevent it from falling. But with the solder paste is different heated red glue curing, the freezing point temperature of 150 ℃, then, red glue from paste directly into a solid.
The following points must be the idea of using red glue:
1 Red glue should be put in the refrigerator 2~8 ℃ preservation, to prevent the temperature changes, characteristics.
2 Red glue to a specific serial numbers, according to feed quantity, date,type number.
3 Red glue temperature requirements at room temperature for 4 hours, by the use of FIFO order.
4 For the dispensing operation, hose red glue to defoaming, red glue ontime sex unused should be put back to the refrigerator, the old glue andglue can not mix.
5 Curing temperature is higher and the curing time is longer, the adhesive strength is strong.
In addition to the red glue, related tools we mall also has many other,such as paste, tin wire, solder ball,Tin absorption line and so on, there is a demand forfriends just to have a look, a large number of preferential waiting for you.
