Regardless, it looks like the drill table was being operated in the bed of a truck while travelling down an unpaved road.

I get better drill registration with the PCB in a vise and a Dremel in my hand.

I still doubt you can do motherboard density. You said it's "only a weekend hobby". Hobby stuff doesn't work that way. I know I can't do that kind of density, and no matter how much money/cm2 somebody offers me, I won't be able to pull that out of my ass without a huge investment.

Still, I will be impressed if that demo board comes out.

By the way, the tiny white lines running across the square pads are an artifact of the way I had to render the graphic. Yet another reason I think you should just take Gerbers. But they're too narrow to matter; they shouldn't give you any trouble.

And 300 dpi?
On a 6/6 design, either gonna get .00333 or .00666.  One is entirely too small, the other out of spec large.
Whatcha gonna do now?
I didn't take it apart.
I turned it on.

The only stupid question is, well, most of them...

Save a fuse...Blow an electrician.

The "professional look" of board it depends of file quality in more than 75 %.
With 1200 dpi black traces , the quality is near industrial released.

I gave him 1200 dpi as he requested.

That's okay, we can check back next week. That should give you some time to finish the board so you can demo your capabilities, as well as give a representative indication of job turnaround times and responsiveness.

I think it's safe to say that when someone wants for example 10 boards, then you are not just competitive with Itead and the likes. So maybe you could give some examples of where your service makes sense? Maybe there is a niche market that I fail to see here?

And if you are really serious, then you had better start accepting gerber files, and not expect people to supply you with 1200 dpi image files. ;)

I think you're really hard on him. He didn't really claim he can do 6/6 and other miniature stuff until you pressed him.. the first post says clearly it's amateur boards (home made), not professional boards.


It's pretty obvious that he learned how to do these boards and did quite enough of them to have some confidence in himself, enough to offer his services for others. Good for him - if I wasn't so busy with other things, I would do it myself.

It's not professional boards, it's not super thin traces, but from the pictures they look like decent boards. Lower your expectations, you can estimate from being home made boards what kind of equipment he has, what kind of printing quality he can accomplish and so on..

If someone wants a board to solder one of his/her breadboard projects and turn it into something more definitive this guys' services could be great.

I know I personally don't go to someone like Itead simply because it takes 3-4 weeks to get a board back. As I'm living in the same country as he is, I know for sure the national post works pretty well and a board would probably get to any place in Europe within 5-10 working days and about 12-15 days for US and other places across oceans... it's certainly much better than waiting 3-4 weeks at the very least (because they get stuck in customs for extra checks) for stuff to come from China.

I hope I am not being to hard on the guy. I am really trying to see the use case for this. If he can do something that our Chinese brethren cannot, then he should point it out.

Maybe even as simple as: if you live <close_to_where_i_live> and you send in your file <just_in_time_for_the_weekend> then you have pretty good chance of getting things in the post next week. Or maybe he could do single sided board with extra thick copper for some power electronics on the cheap. or or or...

Right now I don't quite see why/how I would use this service as opposed to cheapo chinese boards.

No, I'm the one who was being hard on him. He did say "PC motherboard" density, which is just silly, and he still insists he can do that. That said, I might call people out on perceived bullshit, but I don't hold grudges, if he can make good on his claimed capabilities I won't have a problem with this at all. Hell, if he were to demonstrate anything near "motherboard" density I'd etch him an apology on PCB... :-DD

Looks like ok quality, but still an order of magnitude away from PC motherboard density.

I please all users to not insist about PC density boards.

Who want this is free to send me the pcb file to my e-mail and I'll tell him the cost.

PCB's presented are  based on different inquiries.

Who is not really interested , not only  to comment without to be able to post at least some pcb's like these , is better to say nothing.

Dude, when you post an advertisement to a forum, you are opening yourself to criticism, so you better hope you can take it! You said PC motherboard density, so yes, people are going to criticize you for that. If you can't do it, apologize and say you can't, don't tell people to shut up about it.

Now, something positive, before I sound too curmudgeonly - I do like the look of the boards. The tinned traces have a nice "old school" look to them, and I would consider using your service if I were anywhere near you.

But play nicely. You're in a forum - it's a conversation, not a television commercial.

@msdesigner:
For double sided boards, what via size do you prefer for designs?

Repeating yourself does not an answer make. But if you cannot be bothered to answer a simple question (what via size) in a forum, then allow me to reciprocate by not bothering to send you an inquiry by e-mail.  :-//

Dear user  c4757p , I think that is better to show us also your pcb's done.
Only to say something against is not the right way.
Also your " language " used till that moment about my post , shown me your level education.
I'm not obliged to prove my capabilities to nobody, I HAVE ONLY PRESENT SOME PROJECTS OF MINE.
You  can continue to say everything you want.

I'm sorry, but your attitude will make me to ignore you.

Good luck with your projects and your business.

You don't expect people to design their boards by trial and error, do you?

You either have specified constraints that people can work to, or you end up playing cat and mouse with frustrated customers.

I think you're getting a tad defensive here. If you look at this from the business point of view, your typical pcb manufacturer will not require you to show you past project to qualify to have some pcb's made.

So, last time I ask, and try not to get huffy and defensive: "what kind of via size can you do / do you prefer?"

O_o   That seems a bit roundabout... Okay, pretend I just sent you a file with 0.3 mm and 0.5 mm vias in it. Can you do those?

the errors ....could exist of course .......by side of pcb designer .........and also from me !
What I don't like is , if people want latest technology about pcb's ( 0,1 mm traces ..32 layers ............... with 1 $ ...........
That why I have this attitude .............but I realize in fact that they know nothing about pcb's..............

I never played like " mouse with cat with nobody " ........I have a very good references about the ones which ordered pcb's to me.

Is not a business....and never will be .......in pcb's manufacturing. .......I only play !

But you're the one saying you can do "motherboard" quality PCBs...

I'm not saying everyone wants tiny PCB tracks and micro vias, etc. Just that people want to know what you can do! Then they can design boards to your spec. It makes life easier! Don't you want to make it easy for your customers? Or maybe you just want to insult them? o_O
