Shipping 2-3 kg for a reasonable size stencil from China will likely be a few times that though, but it should arrive reasonably fast.

That's quite the stencil. What's the panel size?

Cheers

This is our standard stencil.

Framed like this, it costs around $300.

I was wondering what the "frame" was. The stencils I've seen (at either the PPoE or our current CMs) don't have a frame.

That fits into our stencil printer machines, somehow.

A prof. I know said you need 1/2 of a beer to do fine layout work... that would leave me a small time window as the other 1/2 beer sat there... :^)

If the programmers writing autonomous vehicle software are in the Ballmer peak, will they get charged with DWI?

Grin... that's much above 1/2 a beer. The prof is an Irishman, and would certainly suggest 1/2 a Guinness. and happily consume the other 1/2 in the name of science.

One beer greatly improves my skiing. Same idea.

One rum and coke works about as well.

We have no problems with 0402 in production. Maybe we're just lucky :-)

It seems that it should improve your driving, too. Does the officer buy that story? ;-)

I don't think it does. Driving involves a lot of attention, whereas skiing works better if you don't think about it too much. Crashing while skiing is not usually a big deal. In fact, I worry if I don't crash once in a while on skis. Crashing cars is a nuisance.

Ah, I see. In one, crashing is good. ;-)

If this is a one-off prototpye, then why not consider handplace and hand solder each component?

Interesting, thanks. So you don't generally panelize stuff going through that swoopy new P&P?

Yes, many boards are panelized. Those stencils are downstairs. I'll take some pix. The frames are the same, I think.

Here's one I bought recently. I want to say it was around $150-200 USD including shipping. It has both sides of 4 panelized boards.

It's about 43 x 52 cm and fairly light (~700g), but they packed it with cardboard and sheets of sacrificial material from PCB making- kind of a masonite dense kind of stuff- to keep it intact, so maybe

2kg total.

Sonny Bono would disagree with you.
