My First BGA

Today, I had a chance to lay down my first BGA package. It was an absolutely wonderful experience, granted this guy was a breeze, at 1.27mm pitch.

KiCAD: BeMicro Max 10 Breakout

Let's start this new year off. I have removed all of my old posts. They do still exist but I like fresh starts. Perhaps I will move them elsewhere. This post will be short and sweet:


I have made a template for the BeMicro Max 10 board. It will soon be more than just a template.
