In recent years, smart phones have been developing toward integration, screw removal, and frameless. Many traditional adhesive materials can no longer meet the development requirements of modern smart devices. Because of their excellent performance, hot melt adhesives are used as a new generation of electronic adhesives.

Modern electronic products are becoming more and more intelligent, thinner, and portable. Thinner and thinner electronic devices are required to be smaller and smaller, and the frame of mobile phones is thinner and thinner. After finer precision is required, the fitting gap will naturally be thinner.

Advantages of hot melt machine coating:

1. Sealing: With the narrower frame of the mobile phone, the dispensing width is changed from 1mm to 0.5~0.6mm, and the hot melt adhesive needs to have a better aspect ratio and high bonding strength, and it can ensure that it has sufficient bonding strength . Only when these gaps are sealed, the appearance of the mobile phone will be wetted by rain, which will greatly reduce the possibility of penetration into the interior of the mobile phone and reduce the probability of repairing the mobile phone.

2. Insulation: hot melt adhesive has good insulation, which can effectively reduce the

Leakage and electric shock caused by humid air or other reasons.
