How are FPC connectors soldered? What are the matters to be noted for soldering?

FPC connector is a kind of electrical connector that connects FPC (Flexible Printed Circuit) with PCB (Printed Circuit Board). It is usually used in applications that require connection between flexible circuit board and rigid circuit board. In the process of connection, the correct welding method is very important to ensure the quality of connection. The welding method of FPC connector and matters needing attention are described below. Soldering Methods There are two common soldering methods for FPC connectors: manual soldering and automated soldering. Manual welding needs to be under the control of the operator and requires a certain degree of mastery of welding techniques and operations. Automatic welding is completed by automatic equipment, and the welding quality is relatively stable, but it requires a certain amount of equipment investment and maintenance costs. Precautions (1) Soldering temperature: The soldering temperature of FPC connector is usually 220-240 ℃. The soldering temperature of different types of connectors may be different. Carefully check the soldering specification. (2) Soldering time: The soldering time of FPC connector is usually 2-3 seconds, which needs to be adjusted according to the actual soldering situation. (3) Welding position: The welding position shall be accurate to avoid damaging the connector and causing poor welding. (4) Angle adjustment: The welding angle of the FPC connector shall be adjusted according to the actual situation to ensure the accuracy of the distance and angle between the connector and the PCB. (5) Keep clean: keep clean during welding to prevent dust and impurities from entering and affecting the welding quality. (6) Avoid excessive heat: In the welding process, pay attention to avoid excessive heat to prevent burning FPC connector and PCB, which will affect the connection quality. During the welding process of FPC connectors, it is necessary to follow standardized welding specifications, select appropriate welding tools and equipment, and undergo adequate testing and quality control to ensure the connection quality and reliability of the connectors.
