The soldering temperature to the microstrip board must be less than this. HT-025-1 ●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 260ç. ●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. HT-05-2 ●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-203, and HT-50-1 tabs are attached with high temperature solder (having a melting point of 280ç). 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.
