Boss Laser...

[John Larkin]

My production people plan to buy a Boss laser to blast artwork onto
anodized boxes, to avoid buying polycarb labels. That works nicely:

I sent some FR4 samples to Boss to see if they could blow away copper,
LPKF-style. They can!

Resolution is awesome. They scorched the FR4 a little, so those small
isolated patches were 10 or 20 Mohms to the ground plane. A toothbrush
and some SoftScrub cleaned that up, over 1e12 ohms.

We\'re going to develop a path to go from a PADS pcb layout to whatever
formats the Boss likes. I can\'t Dremel for fine-pitch or BGA parts,
but this should work.

Some of the Chinese engraving lasers are cheap, just a few K$, but
we\'ll go with Boss.

Pay no attention to that man behind the curtain.

is it a fiberlaser? I\'d be surprised if a CO2 laser work very well with a copper,
it\'s very reflective at 10.6um

I think so. I\'ll ask the about the wavelength.

They did a sample of my gold-plated copperclad, and that worked too.
