75 mounting method do not leave a space between the terminator and the microstrip board. make the terminator tab height from the housing and the thickness of the microstrip board the same amount. note: the ht-025-1 type is attached with high temperature solder (having a melting point of 280 ? ). the soldering temperature to the microstrip board must be less than this. mounting is performed by soldering over the microstrip line pattern. the mounting should be completed by soldering within 5 seconds using sn-pb type eutectic solder containing 2 to 5% ag with a soldering iron adjusted to about 260 ? . the resoldering of an item that has already been soldered once and then removed is not effective since solder cracks will develop at the electrode portion. do not leave a space between the terminator and the microstrip board. do not leave a space between the the microstrip board. note: the ht-1-1, ht-1-2, ht-1-3, HT-10-2, ht-20- 3, and ht-50-1 tabs are attached with high temperature solder (having a melting point of 280 ? ). the soldering temperature to the microstrip board must be less than this. note: although the high frequency characteristics will deteriorate somewhat, please attach with some slack in the tabs in order to raise the thermal reliability. ht-025-1 ht-05-2 ht-1-1 , ht-1-2 , ht-1-3 , HT-10-2 , ht-20-3 , ht-30-1 , ht-50-1 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.
