5 n usage precautions 1. plugs (1) insertion and removal of connectors be sure to check the polarity mark before mating the connectors. attempting to forcefully mate the connectors in reverse will ruin or scrape the connectors. (3) precautions these connectors are not suited for external interfaces. note that insertion or removal using excessive twist will result in damage. (2) permissible load placed on the cable after the connectors are mated 1) after the connectors are mated, do not apply a load to the cable in excess of the value indicated in the diagram below. l complete lock type mrf03-6p-0.8d mrf03-6p-1.27 l push-on lock type pulling the cable of the push-on lock type results in the disconnection of the connector. mrf03-6p-0.8d mrf03-6p-1.27 mrf03-6r-smt 9.8n or less 9.8n or less 49n or less mrf03-6p-0.8d-2 mrf03-6r-smt-2 9.8n or less 9.8n or less not permitted 2. receptacles and plug receptacles (1) recommended temperature profile (reference) 1) permitted up to two times with the same conditions; however, there must be a period at room temperature between the first and second times. 2) the temperature indicates the board surface temperature at the connector lead portion. 3) reflow soldering should be performed at a peak temperature of 240?c or less at the surface of the printed circuit board. 4) the temperature profile will change depending on such factors as the size of the board, the solder used, and the solder thickness. (3) precautions 1) a special tray is used in the packaging of these connectors. application of excessive force to the contacts will result in misshaped contacts and the soldering quality will be lost at the time of reflow soldering. for these reasons, dropping or rough handling of the product should be avoided. 2) be careful not to misshape the contacts or fittings if the connectors are inserted or disengaged before soldering. (2) recommended hand soldering conditions soldering iron temperature: 350?c, soldering time: within 5 seconds time 150 10?c 60~90 sec 1~4?c/sec 50 sec max 235?c max 200?c 10 sec surface temperature
