0.4mm Pitch BGA is Awesome

I recently had a conversation with a friend about 0.4mm pitch BGAs. The specific part is the FreescaleKL03 ARM Coretex-M0+ microcontroller in a 1.6mm x 2mm, 04.mm pitch package. That’s a 20-ball wafer scale BGA form factor. I don’t have an … Continue reading

More Beagle CAD Paws

Continuing on from my last post … As I said, I do everything I can to avoid reusing the package footprint when adding the the parts library in Eagle CAD. The schematic symbol can be a different story though. It … Continue reading

How Not to Trick Your BGA Friends

Continuing with yesterday’s theme, I have a couple examples that should have been fine, but due to issues at the board house, improper storage or contamination, ended up very much not fine. Behind door number one, we have an OSP … Continue reading

Let’s Get Small – 0.3mm Pitch BGA

I recently got an email from Practical Components about its new 0.3mm pitch evaluation board and dummy 0.3mm pitch BGA. Now, we’ve been assembling 0.5mm and 0.4mm pitch BGAs for years. Those sizes are kind of not really anything special … Continue reading

BGA Pads with Vias

No. This isn’t a closeup of an owl face. There is still some debate on how best to create a land pattern for a 0.4mm pitch BGA. We recommend solder mask defined pads at that pitch. But that’s not really … Continue reading

What’s your favorite MCU package and why? The DIP is big and easy to use. You can stick it in a breadboard (wireless or soldered), a socket or easily hand solder it. But, it tends to be more expensive and … Continue reading

Picking Packages

A long, long time ago, in a place pretty close to here, picking a form factor was easy. Your CPU came in a 40 pin DIP. Your logic came in 14 or 16 bit dips. You picked resistor sizes based … Continue reading

Bouncing BGAs

I dropped my cellphone on the pavement the other day. That’s bad enough, but in my instinctive attempt to catch it, I actually hit it and increased its downward velocity. Luckily, everything still works. The odd thing is that I … Continue reading

Nightmare on BGA Street

I seem to be in a bit of a BGA mood lately. I do that sometimes – pick a subject and talk it to death before moving on. Well, maybe not quite talk it to death, but at least talk … Continue reading
