Time spent on TPD is never wasted.

Don't ever let me hear you take it's name in vain again!

The pcbs look fairly reasonable... bit thin in places, but at least I managed to expose them the right way around this time...

Rather than mirrored.

If I recall correctly, we had to photo-plot some of the layers mirrored then turn them over onto the substrate for the UV treatment.

That way the filmy bit touched the board, and avoided inaccuracies due to refraction.

God zeity, it's like a trip down memory lane whenever I come down here.

You recall correctly, it stops the UV diffusing around the edges of the mask.

Then you leave it in the ferric a little bit too long & it starts undercutting the resist...

Ho hum...

Oh yes. What was the name of that effect, where the surface looks like coral? Dimpled or something?

We had problems with 90 degree corners because the acid got trapped there, particularly serious on 10 thou tracks. Until we upgraded our home-brew CAD software, we had to post-process little 45 degree chamfers into the plot files.

Yes, 1980s. An advance on the hammer and chisel used to cut out PCB tracks in Norman times.

Would you believe me if I said that my flight was delayed again today?

[TheFaQQer]

It's uncanny, really.

Almost as if you can predict it will happen EVERY TIME

[oracleslave]

Would you believe me if I said that my flight was delayed again today?

What a *** liberty!

[TheFaQQer]

And we're off.

Weekend starts here, folks!!
