WithSMTThe development of the surface mount technology (SMT) processing industry has led to the emergence of some peripheral products. I believe everyone has often heard of itRed glueThis product. Now, JJY solder Paste Manufacturer will share with you what it issmtRed glue? Where is it mainly used?
I. What is red glue
SaidsmtPatch red adhesive, it is actually a kind of polymer compound, and red adhesive belongs toSMTThe material is a one-component epoxy resin adhesive that can be stored at room temperature and cures rapidly when heated. Its main function is to achieve the connection between electronic components andPCBThe circuit board is bonded, but compared with solder paste, red glue cures directly when heated. Its freezing point temperature is150℃When it reaches its freezing point, the red glue directly changes from liquid to solid.
Ii. Properties and Characteristics of Red Glue
The characteristics of red glue include: viscosity, fluidity, temperature characteristics and wettability. Due to its characteristics, it is determined that red glue existssmtThe role played in surface mount technology (SMT) processing is to firmly adhere the partsPCBSurface, prevent peeling.
Iii. Main Applications of Red Glue
Red glue is mainly used in printing machines or dispensing machines. The advantages reflected in the printing method are: high speed and high efficiency; The advantages reflected in the dispensing method are: convenience and flexibility, while the disadvantages are that it is prone to stringing and poor bubble formation.
Iv. The Process flow of Red glue
SMTThe standard process for red glue production is: screen printing-Dispensing glue-Mounting-Curing-Reflow soldering-Cleaning-Detection-Repair-All completed.
V. Precautions for the Storage and Curing of Red Glue
Red glue is suitable2℃-10℃It can be stored in the environment and at room temperature7Days, lower than5℃When the storage is greater than6For a month, here5℃-25℃Can store more than30Oh my God. Attention should be paid to the curing conditions. The higher the curing temperature and the longer the curing time, the stronger the bonding strength, and ultimatelyPCBAThe better the performance of the product is.
