The dispensing work can be carried out smoothly, in addition to the LED dispenser itself more perfect functions, important factors and glue properties also affect the final bonding packaging effect, the operator choose glue should be in strict accordance with the demand of course selection, the use of special glue has certain restrictions on the LED dispenser.
Also called UV glue, is a kind of special glue, due to exposure to sunlight in the ultraviolet UV glue will rapidly solidified, so the internal LED dispensing machine requirements are very high, there are some of the more practical dispensing machine inside the rubber tube is made of amber color rubber, amber glue tube can weaken effect of ultraviolet on the adhesive dispensing machine, so the use of adhesive dispensing is best to use the amber needles on the good.
Red glue is also a common glue used in LED dispensing machine. This kind of compound can be quickly solidified under high temperature, so it will not solidify in the lower temperature environment, which is more conducive to the use of operators,. If you want me to give you a limit, maybe the dispenser needs to be equipped with temperature control to control the properties of the red glue.
AB is a kind of special glue commonly used in industry, the main catalyst for A and B glue barrel barrel, made of mixed adhesive has better effect to use in general, AB glue dispensing machine of double liquid, and the reaction time to a normal use, generally a day to achieve good bonding effect, note that LED dispensing seal better, if the external air enters the reaction speed of interference LED dispensing opportunity AB, so the general inside the dispensing machine to seal work. The internal special material can not stick to the fast response of AB glue di
