@Cornelis van Rensburg?Agreed: The laser method does really work well. I think it is better overall. Mark as an option, you could easily add a laser diode to your cnc.?They have gotten really

I did some really fine pitch work using a cnc3020 but had depth issues where the bed wasn't perfectly level. -I used on of the 30 degree v-bits at about 7-10K rpm?The bits do wear fast.(higher rpms

I’ve tried milling on a mini mill (sieg x1) that I converted, but finally settled for laser. bought a laser engraver off banggood. 3w laser diode i think. clean the pcb with scotchbrite pad/

Also what software are you using for creating the pcb then the isolation paths? wrote:

Hi Mark, Post some pictures of your attempts and the pcb mill so far. Are you shooting for smt fine pitch or general .1" stuff.

I did a bunch of searching but didn't really seen anything appropriate. So here goes ... After building electronic "stuff" for a long time (I started out using vacuum tubes / valves :-), I wanted to

I have a Delta drill press that came with cross hair laser sights. It works after following a long alignment procedure but the beam is too fat to position anything smaller than 1/8". I think I have

Thank you for all your replies and ideas. I have some cheep lasers at MPJA to check out also as I need help due to bad eyes these days at 64 years old. Best Kevin

Clear thin (both width and thickness) strip of plastic. Scrap bit of PCB at each end, pulled taught and affixed to drill bed. Put a scrap PCB underneath and drill through, mark around hole for

You mount the mirror under the table at a 45 degree angle.? You get a cheapie TV camera and focus it on the bottom of the board. Print an overlay on a transparency and either put it on the mirror

Been there, tried that. I experimented with the typical 650nm (red), 5mW laser modules with dot, line and cross-hair lenses available on eBay, Amazon and elsewhere. At the standard intensity the line

I believe right about now cross hairs best idea. Bangood.com in china seem to have parts needed but cost could be expensive.Mount table on pernament wood then mount holders on wood to align I guess.

I'd suggest two crossing lines with the lasers attached to the drill table.? You can often buy "line" lasers that put out a line rather than a point.? If you have difficulty finding some, I'd

The best way, but not the easiest way, is to do what was commercially done a very long time ago: Drill from the bottom and have a laser dot from the top. Of course in the old days it was a cross hair

I just bought a quality drill motor and drill press from Jameco and need help with a laser siteing idea to put a laser dot under board in center of hole to be drilled. Has anyone done this that has a

I got one of those. They can blow individual components away if you aren’t careful. Make sure to get spare heater elements , they are cheap and it won’t cause a project delay if you have them. If

Thanks for all the suggestions :-) I already have a very good soldering iron so I think I'll go for an 858D (just the hot air gun). Again, Many thanks all, Dave

got a picture? make? model? and show what you do with the soda cans.

Hobby Lobby (Craft Stores) sells a tool for leather work .? It is less than $20. Works well for me. Cut up soda cans with scissors to keep the heat off of the protected areas. Start far back and

Received from MVS Sarma at 4/19/2019 03:15 UTC: Perhaps, but lead coatings don't adhere all that well to copper unless the copper is first tin plated. And lead plating is less wettable/solderable
