What are the SMT patch red adhesive printing methods?

WithSMTThe development of the surface mount processing industrySMTThe development trend of the production line is a crucial link.Some peripheral products have also emerged as a result. I believe everyone has often heard of itRed glueThis product. SoSMTWhat are the printing methods of surface mount red adhesive?Now, Shenzhen JJY Solder Paste Manufacturer will explain it to you:

SMTThe surface mount red adhesive printing method: The thickness of the steel mesh holes, as well as the size and shape of the holes, should be determined based on the type of the part and the performance of the base material. Its advantages are high speed and high efficiency.

SMTThe dispensing method of surface mount red adhesive: Dispensing is carried out by using compressed air to apply red adhesive onto the substrate through a dedicated dispensing head. The size and quantity of the adhesive dots are controlled by parameters such as time and the diameter of the pressure tube. The dispensing machine has flexible functions. For different parts, we can use different dispensing heads, set parameters to change, and also change the shape and quantity of the glue dots to achieve the desired effect. The advantages are convenience, flexibility and stability. The drawback is that it is prone to stringing and bubbling, etc. We can adjust the operation parameters, speed, time, air pressure, temperature, etc., to minimize these shortcomings as much as possible.

The needle rotation method involves immersing a specially designed needle membrane into a shallow rubber tray. Each needle tip has a rubber dot, whenSMTWhen the patch red adhesive dots come into contact with the substrate, they will detache from the needle. The amount of adhesive can be adjusted according to the shape and diameter of the needle.

Curing temperature100℃,120℃,150℃; Curing time5Minutes150Second60Seconds.

Typical curing conditions:1The higher the curing temperature and the longer the curing time, the stronger the bonding strength will be.2As the temperature of the surface mount adhesive varies with the size of the substrate parts and the placement position, we suggest finding the most suitable hardening conditions.

The storage of red glue should avoid being left at room temperature for a long time. It is recommended to store it in5℃-10℃The shelf life is6One month.
