For position of the holes, see outline drawing of the power module.
Verify following items before concluding power module
damage.
1）No output voltage
2）Output voltage is high.
Recommended materials of the printed circuit board is double
sided glass epoxy with through holes. (thickness: t=1.6mm)
When several to tens amperes of current flows to output pat-
tern, voltage would drop and heat generation would be higher
for narrow pattern. Relationship between current and pattern
width changes depending on material of printed circuit board,
thickness of conductor, temperature raise allowance. 35mm
copper glass epoxy printed circuit board is shown in Figure2-2
as an example.
For example, when 5A of current flows and temperature rise
below 10℃ are expected, pattern width shall be more than
4.2mm with 35µm copper plate (generally 1mm/A is standard).
Confirmation is definitely necessary for designing because
characteristics shown in figure 2-2 depends on manufactures
of printed circuit board.
