fpc connectors common cautions for use common cautions for use pc board design design the recommended foot pattern in order to secure the mechanical strength in the soldered areas of the terminal. fpc and equipment design design the fpc based on the recommended dimensions to ensure the required connector performance. in addition, carefully check the equipment design and take required measures for the equipment to prevent the fpc from being removed subsequent to a fall, vibration, or other impact due to the fpc size, weight, or the reaction force of the routed fpc. connector mounting in case the connector is picked up by chucking during mounting, an excessive mounter chucking force may deform the molded or metal part of the connector. consult us in advance if chucking is to be applied. soldering 1) manual soldering. ?due to the low pro?e, if an excessive amount of solder is applied to this product during manual soldering, the solder may creep up to near the contact points, or interference by solder may cause imperfect contact. ?make sure that the soldering iron tip is heated within the temperature and time limits indicated in the speci?ations. ?flux from the solder wire may adhere to the contact surfaces during soldering operations. after soldering, carefully check the contact surfaces and clean off any ?x before use. ?be aware that a load applied to the connector terminals while soldering may displace the contact. ?thoroughly clean the iron tip. 2) re?w soldering ?screen-printing is recommended for printing paste solder. y3ft/y3f/y3b y5s ?screen thickness of 120 m is recommended for paste solder printing. ?consult us when using a screen-printing thickness other than that recommended. ?depending on the size of the connector being used, self alignment may not be possible. accordingly, carefully position the terminal with the pc board pattern. ?the recommended re?w temperature pro?e is given in the ?ure below recommended re?w temperature pro?e y3ft/y3f/y3b y5s y5f ?the temperature is measured on the surface of the pc board near the connector terminal. ?some solder and ?x types may cause serious solder creeping. take the solder and ?x characteristics into consideration when setting the re?w soldering conditions. ?when performing re?w soldering on the back of the pc board after re?w soldering the connector, secure the connector using, for example, an adhesive. (double re?w soldering on the same side is possible) 3) reworking on a soldered portion ?finish reworking in one operation. ?for reworking of the solder bridge, use a soldering iron with a ?t tip. do not add ?x, otherwise, the ?x may creep to the contact parts. ?use a soldering iron whose tip temperature is within the temperature range speci?d in the speci?ations. do not drop the product or handle carelessly. otherwise, the terminals may become deformed due to excessive force or the solderability during re?w soldering may degrade. don? open/close the lever or insert/ remove an fpc until the connector is soldered. forcibly applied external pressure on the terminals can weaken the adherence of the terminals to the molded part or cause the terminals to lose their evenness. in addition, do not insert an fpc into the connector before soldering the connector. when cutting or bending the pc board after mounting the connector, be careful that the soldered sections are subjected to excessive forces. other notes when coating the pc board after soldering the connector to prevent the deterioration of insulation, perform the coating in such a way so that the coating does not get on the connector. the connectors are not meant to be used for switching. to determine the relationship between the screen opening area and the pc board foot pattern area, refer to the diagrams in the recommended patterns for pc boards and metal masks when setting. note that excess solder on the terminals prevents complete insertion of the fpc, and that excess solder on the metal clips prevents the lever from rotating. note that excess solder inhibits the slider lock operation. te rm inal paste solder pc board foot pattern 150 c 180 c 230 c 220 c 200 c 260 c temperature upper limit (soldering heat resistance) lower limit (solder wettability) preheating peak temperature time 25 sec. 70 sec.60 to 120 sec. 250 c 200 c 180 c 150 c time peak temperature preheating 60 to 120 sec. min. 200 c, 70 sec. te mperature 260 c 200 c 180 c 150 c time peak temperature preheating 60 to 120 sec. min. 200 c, 70 sec. te mperature do not the soldered areas to be subjected to forces panasonic-electric-works.net/ac for other details, please verify with the product speci?ation sheets.
