Controlled Volume NPI - TTM

TTM is one of my favorite fabricators.  TTM has great customer service and excellent stackup designers.  Advanced and Engineering Capabilities.

So what is "Controlled Volume NPI" ?

This just a another buzzword for cutting edge (advanced) capabilities.

Example Controlled Volume NPI  Design Technology:

Drill / Pad = 8 / 16mil  (0.2 / 0.4mm) Thru-Hole Vias with VIPPO
Trace / Space = 3 / 3.25mil

As the title implies this is not high volume production. It is for low volume specialty designs which require special handling by a highly experienced fabricator with advanced capabilities.

And it's going to be a bit more expensive $$$

That's It !

10A 0402 Zero Ohm Resistor

For those times when you need a bigger zero ohm 0402 resistor :)

All zero ohm resistors are not equal and some maybe good fuses if your not careful.

KOA comes to the rescue. See KOA P/N TLRZ1ETTB
