Board to board soldering: BGA/SMD style

NeoY2k · 7th December 2008, 05:36 PM

Hi!
I made a board for linear regulators, a bit on the "universal" side (should serve me in many projects). It's designed to use the LT1963 or LT1763 chips that are pin compatible.

However, I would avoid making another board to do a neg version of it, using the LT1964, as this chip is NOT pin compatible with the LT1763 - quite sad.

These chips are SMD devices.
I thought I could make a small board to be a pin adapter.

So this board would receive a SOT5 device on top of it (no problem here) and be soldered on the SO8 footprint on my regulator board.
This board would be soldered like a smd chip - more like a BGA chip.

Do you think it is possible? Using solder paste / reflow oven.

I think it should work, I'm not absolutely sure about it but...

Thanks!
Nicolas
