Soldering and Cleaning Condition
8-1. Mounting Method
(1) Mounting Holes on PCB
There is the recommended diameter of hole and pad of PCB in Table 8-1.
The mounting hole position is in Fig.8-1.
Also, see outline drawing for outline of the power supply.
(2) Recommended Material of PCB
Recommended materials of the printed circuit board is double sided glass epoxy with through holes.
(thickness : 1.6mm, copper : 35µm)
(3) Input / Output Pattern Width
Large current flows through input and output pattern. If pattern width is too narrow, heat on pattern
will increase because of voltage drop of pattern. Relationship between allowable current and pattern
width varies depending on materials of printed circuit board, thickness of conductor. It is definitely
necessary to confirm on manufactures of printed circuit board for designing pattern.
(4) Method of Connecting Terminals
CVin, -Vin, +Vout, -Vout, COM with consideration of contact resistance.
