Always use either thermal grease or a thermal sheet.If processing thermal grease, apply it thinly and evenly.Also, when processing the thermal sheet, make a hole according to the position of the screw.If the four corners are cut as shown in the fi gure below, stress may be applied to the edges of the base plate during fi xing, which may damagethe built-in parts, so avoid such processing.Good Bad BadImage of using thermal sheet and precautions when processing!The unit can be mounted in any direction. When two or more power supplies are used side by side, position them with proper intervals toallow enough air ventilation. Aluminum base plate temperature around each power supply should not exceed the temperature range shownin derating curve.!Avoid placing the AC input line pattern lay out underneath the unit, it will increase the line conducted noise. Make sure to leave an ampledistance between the line pattern lay out and the unit.Also avoid placing the DC output line pattern of DC-DC converter underneath the unitbecause it may increase the output noise. Lay out the pattern away from the unit.!High-frequency noise radiates directly from the unit to the atmo- sphere. Therefore, design the shield pattern on the printed circuit boardand connect its one to FG. The shield pattern prevents noise radiation.Stress onto the pins!When too much stress is applied to the pins of the power supply,the internal connection may be weakened. As shown in right fi gureavoid applying stress of more than 29.4N(3kgf) on the input pins/output pins(A part) and more than 9.8N(1kgf) to the signal pins(Bpart).!The pins are soldered on PCB internally, therefore, do not pull orbend them with abnormal forces.!Fix the unit on PCB(fixing fittings) to reduce the stress onto the pins.Soldering!Flow soldering: 260C less than 15 seconds.!Soldering ironAC IN/DC OUT/R pins: 450C less than 5 seconds.Signal pins: 350C less than 3 seconds(less than 20W)AA partLess than 29.4N Less than 29.4N(3kgf)(3kgf)Less than 29.4N(3kgf)BLess than 9.8N(1kgf)AB partLess than 9.8N(1kgf)Less than 9.8N(1kgf)DPF-4
