High Speed, Matched-Impedance, Parallel Board-to-board Connector Receptacle (2 required) IT1 Series Outline High-speed matched-impedance parallel board-to-board connector designed for applications requiring board-toboard spacing with transmission speeds exceeding 1GHz. The connection system has matched impedance of 50 ohm or can be customized. Contacts are on 0.5mm pitch. Features Transmission Module Connection Cross-Sectional Diagram 1. 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 50 ohms, for standard product. 2. Supports Multiple Connectors per board Designed with a tolerance of +/- 0.2mm for both the X and Y-axis. The three-piece structure and the +/- 0.2mm tolerance allows 3 or more IT1's to be mounted on a single board. (0.65) : Wipe Nov.1.2019Copyright2019HIROSEELECTRICCO.,LTD.AllRightsReserved. IT1 Series Receptacle 2-Point contact 4-Layer board (Impedance matching) 3. Customized Board-to-Board Distance Board-to-board distance can be customized, from 16mm to 40mm. Ground lines or additional traces can be added to support high level, high speed transmission or mixed power/signal applications. Transmission Module 2-Point contact 4. Signal to Ground Ratio The standard signal-to-ground ratio is 10:2, which makes reliable matching of the characteristic impedance of each transmission line. This ratio also can be customized. Receptacle 5. Contact Reliability Use of double contact points on each of the contacts assures highly reliable performance. Applications Routers, servers, base stations and other telecommunication equipment.

Stationary side (Longer) Extraction Tool Used to release the transmission module from the stationary receptacle. Extraction Tool (2 required) Fully Connected Condition The interconnection package consists of 3 main sub-assemblies: Two receptacles and the Transmission Module. The transmission module, held securely by the guide frame has a mating/un-mating side and a stationary side.

Recommended Design Guidelines 2-1 Solder Land Pattern When placing the receptacles on the Printed Circuit Boards using automatic mounting equipment or manually, assure that the correct diameters of the holes (Fig. 1) are through the entire thickness of the board. SLocating post hole diameterS The contacts of receptacle assembly are exposed on the bottom surfaces. The exposed areas of the contacts are a distance of 0.25 mm minimum from the surface of the Printed Circuit Board, on which the receptacle assembly is placed (Fig.2). Consideration should be taken not to place or assure insulation of conductive traces under the receptacle assemblies. Nov.1.2019Copyright2019HIROSEELECTRICCO.,LTD.AllRightsReserved.

Wash the assembly as recommended below. SCleaning ConditionsS <Organic Solvent Cleaning> Nov.1.2019Copyright2019HIROSEELECTRICCO.,LTD.AllRightsReserved. <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, which describes its effects on metals and resins. Care should be taken not to leave moisture on the connectors. A306 <Cleaning Precautions> Residual flux or cleaning agent remaining on the connectors when cleaning with organic solvents or water based cleaners may cause deterioration of the electrical performance. It is important to check that a thorough washing has been performed. IT1 SeriesHigh Speed, Matched-Impedance, Parallel Board-to-board Connector System 4. Mating Procedure Follow the procedure described below. Note:The transmission module must be fully inserted into receptacle assembly already placed and soldered to a board. The Transmission Module cannot be exposed to heat temperatures of the soldering process. Step 1 Receptacle Placement on the board - stationary side Nov.1.2019Copyright2019HIROSEELECTRICCO.,LTD.AllRightsReserved. Assure that the orientation posts are aligned with the holes on the board. When specifying receptacle assemblies without the orientation posts exercise extra caution to assure correct orientation and connection with the solder pads. Step 2 Insertion of the Transmission Module Fully insert the Transmission Module in the board-installed receptacle assembly. It is critical that the insertion is done straight and uniformly. Step 3 Mating/un-mating Assure that the receptacle assembly is correctly aligned with the Transmission Module. Fully insert the receptacle assembly on the Transmission Module. It is critical that the insertion is done straight and uniformly. Step 4 Connection completed A307 IT1 SeriesHigh Speed, Matched-Impedance, Parallel Board-to-board Connector System 5.
