Should I mount AC DC converter on PCB as a through-hole component, a surface-mount component, or have a header that this component is plugged into?

I need to figure out how to physically mount the following AC-DC converter to a PCB to be used as part of a regulated power supply. The pin height is min 3.0 mm.

The recommended footprint is for through-hole mounting. It is referred as an SIP package, which stands for the single inline package.

It would be best to mount it this way. If the design did absolutely not permit this, then you could probably lay long rectangular pads on a PCB and mount them like a SMD component. Beware you may have to de-rate the thermal properties of the IC, as it was likely tested while through-hole mounted.

You could always use a header, but that would only be warranted if you felt you would need to replace or change this component often.

What Others Are Asking

When you want to make a PCB, what informations are necessary to provide to the PCB manufacturer?

I am a mechanical designer. I have sent my PCB design file to manufacturer. But they said the data may be not enough. So what data are you used to send to your PCB manufacturer.

Is there a reason an 0805 resistor would have a different land pattern than an 0805 capacitor?

My PCB design software comes with some libraries that include some common components, like chip resistors and capacitors. I have noticed, however, that the footprint land pattern for the 0805 resistor is not identical to the 0805 capacitor. Is there a “best standard”? IPC-7351, IPC-SM-782, or what?

How can I solder an SMD component with a pad on the bottom?

I am getting a PCB manufactured for a project that I am working on. One of the parts, the A4950 motor driver, has a “pad” on the bottom, which is meant to be soldered to GND of the PCB for thermal dissipation. I was thinking about the prototyping, and I am unsure how I would go about (using a soldering iron), soldering the pad on the bottom.
