Where is the FPC glue dispenser mainly used

source：m.5songhua.com | Release time：2025年05月13日

The FPC glue machine is mainly used for dispensing flexible printed circuit boards (FPCs) and is widely used in the field of electronic manufacturing. The following are some of the main application scenarios:
1. FPC production and manufacturing
Circuit board packaging: In the FPC production process, it is necessary to package and protect electronic components such as chips, capacitors, resistors, etc. on the circuit board to prevent them from being affected by the external environment. The FPC glue dispenser can correctly apply glue dots around the components or the entire surface of the circuit board, forming a protective film that plays a role in moisture, dust, and corrosion prevention.
Reinforcement board pasting: During the use of FPC, some key parts such as connection ports, bends, etc. require the addition of reinforcement boards to improve their mechanical strength and reliability. The FPC glue dispenser can evenly apply glue on the bonding surface between the reinforcing board and FPC to ensure a firm connection between the two, while ensuring the correct amount of glue is used to avoid glue overflow and affecting the appearance and performance of the product.
Electromagnetic shielding: In order to prevent electromagnetic interference generated by electronic components on the FPC from affecting other components, or to prevent external electromagnetic interference from affecting the normal operation of the FPC, a layer of adhesive with electromagnetic shielding properties is usually coated on the surface of the FPC. The FPC glue dispenser can correctly apply electromagnetic shielding adhesive to a certain position according to design requirements, forming a uniform shielding layer and effectively improving the electromagnetic compatibility of FPC.
2. FPC assembly and maintenance
Component fixation: When assembling FPC with other electronic components or parts, it is necessary to firmly fix FPC in a certain position. The FPC glue machine can glue on the contact surface between FPC and connecting components, achieving reliable adhesive fixation and ensuring that FPC will not shift or fall off during product use.
Sealed and Waterproof: For some electronic devices that need to be used in humid or harsh environments, such as mobile phones, tablets, digital cameras, etc., their internal FPC needs to be sealed and waterproof. The FPC glue dispenser can apply waterproof glue at the interface, gap, and other positions of the FPC, forming a sealing ring or adhesive layer to prevent moisture and dampness from entering and improve the waterproof performance of electronic devices.
Repair and glue repair: In the process of repairing electronic devices, if the glue on the FPC is found to be aging, falling off, or the components are not firmly fixed, it is necessary to carry out glue repair treatment. The FPC glue dispenser can correctly replenish the glue to the parts that need to be repaired, restoring the performance and reliability of the FPC.
