@Max: LPKF is for quite many years. But now, we need four layers and more. May be good to test 3gbps high speed serial communication!

@Duane: Yes, I have seen this in many US Military products and also reversed engineered them. However, those assemblies were also epoxy potted.

One of application has high voltage requirement.

@elizabeth: Can they employ some form of Cu ribbon to keep Cu trace and low power laser drill for vias?

@hm, Max.....The best thing I have seen that would kinda be affordable for home use is a 2-D router that can cut the copper layer and thus form tracks.  Because there is copper everyehwere, not just where there are tracks, the PCBs look a bit unusual, but it works fine.  I have no idea how much they would cost, though...

@betajet: LPKF is still going strong -- they have both mechanical milling and lasers.  Resolution keeps getting better.

I just bounced over to their website ... VERY Tasty!!!

@elizabeth: It's unlikely that there would be a low cost tool to make PCBs using the 3D printing approach since you would need to print an insulating substrate followed by (or combined with) metal. All the low cost 3D printers I know about can only do plastic...

Oh, is that what this person was asking -- my bad -- I thought it was a generic question about how to make your own printed circuit boards at home.

@Duane: Have you seen this technique? I understand it went to the moon and back.

I haven't seen one in the flesh (although I would love one for my collection), but I have seen it before. As you say, it was called the cordwood technique -- it actually offered tremendous packing density for the time -- I'm always amazed by the different techniques folks come up with...

@_hm: I am wondering, is there low cost tool for 3D prinitng of PCB to get them faster and at lower cost in your home?

I have a couple of friends who make their own PCBs -- I remember once chatting with one of them about a small project idea in the morning, and he called me in the afternoon to say that he'd made a prototype PCB and one populated with components was already in the post to me. I will ask him if he woudl be interested in posting some articles on this here on PCB Designline.

@Caleb: I do however LOVE the asthetics of a PCB and plan on keeping a close eye on this designline if only for the visuals!


I will do my very best to keep your eyes fed with tasty visual fodder :-)

Like many of you, I was saddened to hear the news of Leonard Nimoy's death. His Star Trek character Mr. Spock was an inspiration to many of us who entered technical fields.
