NEW High Speed, Matched-Impedance, Parallel Board-to-board Connector System IT Series (2 required) IT Series Outline High-speed matched-impedance parallel board-to-board connector designed for applications requiring board-toboard spacing with transmission speeds exceeding GHz. The connection system has matched impedance of 5 ohm or can be customized. Contacts are on.5mm pitch. Features. Impedance Matching using a 4-Layer Board The innovative transmission module uses PC boards with a strip line design of transmission lines, providing matched impedance of 5 ohms, for standard product. 2. Supports Multiple Connectors per board Designed with a tolerance of +/-.2mm for both the X and Y-axis. The three-piece structure and the +/-.2mm tolerance allows 3 or more IT s to be mounted on a single board. 3. Customized Board-to-Board Distance Board-to-board distance can be customized, from 6mm to 4mm. lines or additional traces can be added to support high level, high speed transmission or mixed power/signal applications. 4. to Ratio The standard signal-to-ground ratio is :2, which makes reliable matching of the characteristic impedance of each transmission line. This ratio also can be customized. 5. Contact Reliability Use of double contact points on each of the contacts assures highly reliable performance.

Time (Seconds) BCleaning Conditions Organic Solvent Cleaning Solvent Type Normal temperature Heated IP (Isopropyl alcohol) HCFC (Hydrochlorofluorocarbon) Water Based Cleaning When using water based cleaning agents (e.g., terpene, and alkali saponifiers), select the cleaning agent based on the documentation issued by the various manufacturers of cleaning agents which describes the effects on metals and resins. Care should be taken not to leave any moisture on connector assemblies. Cleaning Precautions Residual flux or cleaning agent remaining on the connectors when using organic solvents or water type cleaners may deteriorate electrical performance. It is critical to dry parts completely. BConnector Handling Precautions. Effective mating length (Wipe) The mating length of this product is.2 mm for contacts and.95 mm for B contacts. Please use a range of values from the setting value to the setting value plus.6 mm for the stacking height. 2. Mounting between Boards void supporting the boards only with connectors. Use other mechanical supports. 3. Solder Repair Flux coating at the time of repair can result in the flux wicking up to the contact areas of the connector. This can cause poor contact. The connector should be cleaned in accordance with the recommendations above. 4. Connector Mating Structure IT Series connectors are designed as a 3-piece assembly comprising of 2 receptacles and a single transmission module. The transmission module has mating side and a fixed side. Once the fixed side has been inserted, it cannot be removed without a tool. Having one side of the transmission module fixed in this assembly, allows repeated mating/unmating of the other side.

5. Connector Mating Procedure Install the receptacle on PCB(Reflow soldering) DO NOT USE transmission module in soldering process. Step Mate the fixed side of the transmission module in the installed connector. Caution: Check that the fixed side is oriented in the proper direction. Mating side 68 Transmission module Fixed side 9 (Mounted) Board Step 2 Mate the removable connector side on the transmission module.this connector can be mated/unmated repeatedly. 68 Transmission module fixed in receptacle 6. Connector Unmating DO NOT REMOVE one side only or ''wiggle'' side-to-side. 68 9
7. Removing the Transmission Module To remove the fixed side of a mated transmission module, use dedicated tools, IT-Ejection Tool and remove the transmission module according to the procedure of the diagram below. Step Use the IT-Ejection Tool to release the latch formed by the receptacle's tabs on metal fitting. IT-PICKER()-Ejection Tool 68 Step 2 Pull out the transmission module when tabs are in the released condition. Ejection Tool Lock Tab 68 Metal Fitting 8. Miscellaneous Depending on the manufacturing lot there may be slight differences in color shades of the insulator materials. The form, fit and function of the interconnection system is not affected.
