On: Comparing Hobby PCB Vendors

I've placed probably 20-50 orders through JLC. Very consistently decent quality, and surprisingly good customer service, they manually check every design within a few hours and will email with issues and/or their adjustment.

Tip for smallish boards: "Panel by JLC" can further drop the price. It's often cheaper to buy say 10 units of a 2x2 panel than to buy 40 individual boards.

I was stunned to see they added teflon substrates recently (for RF layouts. I've paid $1000s for teflon fab); very excited to try that out.

I’m curious what you mean about Teflon? Because it’s flexible?

Because it's an exceptional dielectric material, making it particularly well-suited to radio frequency applications at microwave frequencies.

It has very low loss (more than 10x less than FR4), and low dielectric constant, and both stable up to very high frequencies
