●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-025B-1 type is attached with high
temperature solder (having a melting point of 280ç).
The soldering temperature to the microstrip board
must be less than this.
●Mounting is performed by soldering over the
microstrip line pattern.
●Manual Soldering: 350ç max. for 3 sec. max.
●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-10-2, HT-20-3, and HT-50-1(40) 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.
