6 precautions and use recommendations 1. do not immerse or clean the entire connector with cleaning solutions as this may affect proper operation of the ejection mechanism and electrical performance of the connector. clean only the soldered termination areas. 2. do not apply excessive force to connector when handling or after installation on the pc board. 3. the connector will reliably connect and function with the correctly inserted microsd tm or transflash tm cards. the connector will not allow reverse insertion of the card. do not force reverse oriented card in to the connector as this may cause permanent damage to the card or connector. 4. do not use force when removing the inserted card from the connector. 5. protective cover recommendations. to avoid accidental damage to the connector or electrical discontinuity when the device may be accidentally dropped it is recommended to have a removable, sliding or hinged protective cover, as shown on the illustration below. 6. recommended application area for surface mounting adhesive surface mounting adhesive must be applied on the pcb only in the area indicated on the illustration below. excessive amount of the adhesive may affect the soldered termination leads. use only the minimum required amount of adhesive. 7. the connector must be correctly mounted on the pc board before the card can be inserted. do not insert card in the un-mounted connector. (17.55) (17.95) protective cover 7.7max 0.5max apply the adhesive only in this area. 9.6max 11.4max recommended adhesive: somakote ir-010h-3 (manufactured by somar corporation) the product information in this catalog is for reference only. please request the engineering drawing for the most current and accurate design information. all non-rohs products have been discontinued, or will be discontinued soon. please check the products status on the hirose website rohs search at www.hirose-connectors.com, or contact your hirose sales representative.
7 8. mounting on the flexible printed circuit (fpc) to assure correct performance it is recommended that a flat reinforcement plate 0.3 mm min. thick be used under the fpc. 9. to assure card guidance during insertion and the protection of the exposed edge when fully inserted it is recommended that the users housing be designed as illustrated below. 10. the edge of the moveable tray may be visually slanted as shown on the illustration below. this has no affect on connector performance. 11. small visible residual manufacturing oils or tooling marks do not affect connector performance. 12. repeated insertions and removal of the cards may leave some marks on the card itself. this will have no affect on the connector prformance. 13. the card detection contacts are exposed. exercise extra caution during handling and installation on the pc board as to avoid damage or contamination to them. 0.7 max. 0.45 board microsd card (0.9) card detection contact the product information in this catalog is for reference only. please request the engineering drawing for the most current and accurate design information. all non-rohs products have been discontinued, or will be discontinued soon. please check the products status on the hirose website rohs search at www.hirose-connectors.com, or contact your hirose sales representative.
