6 / 7 page Panasonic Corporation Automation Controls Business Unit industrial.panasonic.com/ac/e NOTES FOR USING SMD TYPE CONNECTORS (Common) ACCTB10E 201201-T Regarding soldering 1. Reflow soldering 1) Measure the recommended profile temperature for reflow soldering by placing a sensor on the PC board near the connector surface or terminals. (The setting for the sensor will differ depending on the sensor used, so be sure to carefully read the instructions that comes with it.) 2) As for cream solder printing, screen printing is recommended. 3) See the specifications and drawings for the product in question for the metal mask pattern diagrams. 4) When mounting on both sides of the PC board and the connector is mounting on the underside, use adhesives or other means to ensure the connector is properly fixed to the PC board. (Double reflow soldering on the same side is possible.) 5) N2 reflow, conducting reflow soldering in a nitrogen atmosphere, increases the solder flow too greatly, enabling wicking to occur. Make sure that the solder feed rate and temperature profile are appropriate. Soldering conditions Please use the reflow temperature profile conditions recommended below for reflow soldering. Please contact us before using a temperature profile other than that described below (e.g. lead-free solder). • Narrow-pitch connectors (except P5 floating and P8 type) • Narrow-pitch connector (P5 floating, P8) For products other than the ones above, please refer to the latest product specifications. 6) The temperatures are measured at the surface of the PC board near the connector terminals. (The setting for the sensor will differ depending on the sensor used, so be sure to carefully read the instructions that comes with it.) 7) The temperature profiles given in this catalog are values measured when using the connector on a resin-based PC board. When performed reflow soldering on a metal board (iron, aluminum, etc.) or a metal table to mount on a FPC, make sure there is no deformation or discoloration of the connector beforehand and then begin mounting. 2. Hand soldering 1) Set the soldering iron so that the tip temperature is less than that given in the table below. Table A 2) Do not allow flux to spread onto the connector leads or PC board. This may lead to flux rising up to the connector inside. 3) Touch the soldering iron to the foot pattern. After the foot pattern and connector terminal are heated, apply the solder wire so it melts at the end of the connector terminals. 4) Be aware that soldering while applying a load on the connector terminals may cause improper operation of the connector. 5) Thoroughly clean the soldering iron. 6) Flux from the solder wire may get on the contact surfaces during soldering operations. After soldering, carefully check the contact surfaces and clean off any solder before use. 7) For soldering of prototype devices during product development, you can perform soldering at the necessary locations by heating with a hot-air gun by applying cream solder to the foot pattern beforehand. However, at this time, make sure that the air pressure does not move connectors by carefully holding them down with tweezers or other similar tool. Also, be careful not to go too close to the connectors and melt any of the molded components. 3. Solder reworking 1) Finish reworking in one operation. 2) For reworking of the solder bridge, use a soldering iron with a flat tip. To prevent flux from climbing up to the contact surfaces, do not add more flux. 3) Keep the soldering iron tip temperature below the temperature given in Table A. 60 to 120 sec. Preheating Peak temperature 200 °C 220 °C Upper limited (Solder heat resistance) Peak temperature 260 °C 230 °C 180 °C 150 °C 70 sec. 25 sec. Lower limited (Solder wettability) Time Temperature 60 to 120 sec. Preheating Time Temperature Peak temperature 200 °C 155 to 165 °C 245 °C max. Within 30 sec. Product name Soldering iron temperature SMD type connectors 300 °C within 5 sec. 350 °C within 3 sec. Apply the solder wire here Terminal Pattern PC board Small angle as possible up to 45 degrees |
