IC Sockets XR2 OMRON’s IC Connectors Have Excellent Reliability and Can Tolerate Momentary Interruptions in Power. Ideal for Highspeed Data Processing. * ■ Round pins and 4-point (4-finger) contact construction ensure long life and excellent shock and vibration durability. ■ Contact entry holes are large for easy insertion. ■ IC lead contacts placed high for solid connections. ■ No flux rise. ■ A wide product range: open-frame, closed-frame, single-row, carrier-type DIP terminals, wrap terminals, solder-sleeve terminals, and low-profile DIP terminals. ■ A new tin-plated product series offers more choice when it comes to selecting the optimum IC Socket for an application. ■ Conform to UL standards (file no.

Removing ICs • Use the XY2C-0101 or XY2C-0103 IC Removal Tool to remove ICs. • Do not use a screwdriver to remove the IC. It may damage the circuit board. • Do not use a testing rod or check pin to check contacts or circuits. This may damage the inner clips or plating and may lead to improper contact. • Four-point contact construction is used for plated products to make them more tolerant of momentary power interruptions. We recommend using gold-plated contacts in areas subject to vibration and shock. Automated Soldering Conditions (Jet Flow) Applicable IC Lead Dimensions 1. Use leads that are within the range shown here. For details, refer to page 2. Use an IC with leads longer than 3 mm. If the leads are too long, the IC will not sit flush on the board. 2. Use an IC with tapered leads for easy insertion, a minimum amount of bending, and minimum damage to the leads. NG OK OK 1. Soldering temperature: 250±5°C 2.
