11 / 12 page 11 DF50 Series●1 mm Pitch, WtoB, Positive Lock Connector 1.Recommended temperature profile Note 1: Up to 2 cycles of Reflow soldering are possible under the same conditions, provided that there is a return to normal temperature between the first and second cycle. Note 2: The temperature profile indicates the board surface temperature at the point of contacts with the connector terminals. 2.Recommended manual soldering Manual soldering: 350ç±10ç for 3 to 4 seconds 3.Recommended screen thickness and open area ratio (Pattern area ratio) Standard thickness 0.1mm Open area ratios:100% 4.Board warpage Maximum of 0.02mm at the connector center, with both ends of the connector as reference points. 5.Cleaning conditions Refer to “Nylon Connector Use Handbook”. 6.Precautions ▪ Mating and un-mating of the connectors when not soldered on the boards is not recommended as this may cause deformation of the terminals, damage to the contacts or insulators. ▪ When mating/un-mating do not twist or lift by the corners. Apply the forces evenly across the entire length and width of the connectors taking care NOT to damage or deform soldered terminations. ▪ Slight discoloration on the insulating materials will not affect form, fit or function of the connectors. ■ Usage Recommendations TIME (sec) 180ç 100 150 200 250 220ç PRE-HEATING TIME SOLDERING TIME MAX 250ç 90 ~120sec 60secMAX 10secMAX 0 |
