The use of FPC connectors and precautions We know that because of the standard type of FPC Connector difference between the many, so the use of the connector method is still not quite the same. For example, how to distinguish between the upper connection, lower connection and double-sided connection methods, the first general look at the FPC connector metal terminal pin contact surface is above or below, if it is above the connection method, if it is below the connection method for the lower connection. There is also a double-sided connection method, which can be once inserted after lifting the double-sided connection method, the principle is to support the connection of the upper and lower connection, in addition to the most current application is the FPC connector double-sided connection this method of use. In the use of FPC need to pay attention to the following matters.
1, on the FPC connector lock cover open, in the operation of opening the lock cover operation should not be too strong, otherwise it is easy to form a lock cover deformation and breakage. Second, excessive force will lead to the lock cover pressed against the connector to open, then there may be the formation of the connector terminal deformation or broken problem. 2, as FPC connectors are generally composed of multi-core pins, on the connector in the connector to try to avoid the connector swing or shaking, or else the formation of FPC connector plug connection position offset is not fully plugged, which will lead to the impact of the use of the connector. 3, in the use of FPC connectors in the process, the connection of the line do not randomly to pull and rip the phenomenon, otherwise it will lead to the use of FPC connectors on the formation of some data anomalies or the loss of the problem situation. 4, FPC connectors do not tilt inserted to avoid the connector pins are not fully in place between the connection. Should be allowed to FPC connector pins at right angles for slow insertion. 5, if the FPC connector pin end pin directly exist broken or bent condition, in order to avoid the problem of safety hazards, do not apply to the application, should immediately be selected for replacement, otherwise the formation of the connector between the lines of poor transmission, thus triggering some short-circuit phenomenon, in serious cases may directly burn the connector. 6, when welding FPC connectors, it should pay attention to the pad operation reflow soldering in which the solder should not increase too much, otherwise the connector terminal welding instability or the formation of false solder phenomenon.
