[FS]: Cheapest tinned printed circuit boards (PCB's)

[msdesigner]

Hello everybody,

   I present you attached the cheapest manufacturing way, for single (double) pcb layer ( home made ) with semi-professional look , starting with 0,0375 Euro / cm2. ( around 0,05 USD / cm2 )


 Can be also TINNED  the copper traces and pad's  and with SILKSCREEN ( components mask with back color ).

If someone ( without technical possibilities and required time ) need to build a prototype board or very small quantity ( up to 10 pcs / pcb ) , please feel free to contact me to : msdesignerpro@gmail.com

 I can deliver you all over the world , in cheapest way , through National postal mail services.


 Kind Regards,

 MSdesigner Pro

Seeedstudio is cheaper if you order 10 boards. And they are professionally manufactured, with soldermask/silkscreen.

What's your USP?

[msdesigner]

 Of course that specialized firms ( factories ) can make cheaper but the problem seems to be quantity  , as you already mentioned.
But not only the quantity is the rule..........the main rule remain ordered surface / order.

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.
Most of presented pcb's are done it from jpeg images with 300 dpi ( 600 dpi sometimes )

TINNING is better than SOLDERMASK ( sometimes ) ,,,,,,,, and is more expensive.

Anyhow I don't want to compete with nobody ....'cause is only a weekend hobby and will  remain like this.

My pcb's are done for prototyping , home made application and for private use.

The minimum order to me is one pce !!! ( and never mind the minimum size / pcb )

All the best,

Mihai

Can you post a picture of a board made with SMT ICs? Can you do TSSOP packages etc.

Please post your minimum track widths and minimum spacings

[msdesigner]

 Christopher, I please you to send me an e-mail ( from your private one ) , and I will search for some picture ( in my archive ) as you have asked.

If you have something with SMT please send there the file and I'll give you complete details.

Regards,

Mihai

 already uploaded picture called : CIRCUIT-IMPRIMAT-DUBLU-STRAT-STICLO-FR4-SMD.jpg  ( green FR4 board ) has mixed SMD + ordinary components.

Those are some fat traces! Come on, I can do 8/8 in my kitchen! Post a demo that actually shows your capabilities...

[msdesigner]

Here is only a general presentation.
I already mention above , that can be obtain the 0,1 mm traces width spaced at 0,1 mm ,from 1200x1200 dpi pdf  print quality.
Any project is different, and pcb's are done in different way according file accuracy and density of traces / pad's.   

I manufacture pcb's ONLY the one's without technical possibilities and of course I'm not the one able to do that.

Is not the enough " space " here to talk anything in " general " .

Thanks for your understanding.

Mihai

[Skimask]

I smell something.
Can't quite put my finger in it though...

[c4757p]

iTead demo card

Make one.

You don't need my PCBs to just show us your capabilities. Either you can do 6/6, 8/8, or whatever, or you can't!

[GeoffS]

How about you post a list of your capabilities for every one to read, not just those that send you an email?

[msdesigner]

OK!....I will post also a DEMO BOARD but can say " nothing" till I can't see the real pcb project.

How about you post a list of your capabilities for every one to read, not just those that send you an email?

[c4757p]

Why? If your capabilities are well defined you should be able to do anything within them.

[c4757p]

No, I'm not interested. As I said, I can do these in my kitchen... And keep your communication in public like an honest person. Why do you think you can't say anything on the forum??

[msdesigner]

My friend, I'm sorry but I really have not so available time to spend on this forum.
That why I can not say anything on this forum.

I'm mechanical engineer , and PCB's manufacturing is just a weekend's hobby.
I'm from Romania , and I try to help  as much as I can all people interested to make own PCB.
As you already seen in posted pictures .......there is not the " high-end technology " of pcb's manufacturing.

So, I hope that you understand in finally my point of view.

All the best,

Mihai

I can make the traces and pad's with density as PC motherboards. ........but I had not till the moment any inquiry like that.

Right. And I can make a fully functional jetpack in my basement - I just never bothered to do it.

[msdesigner]

You can find below some other pcb's of mine.

[Skimask]

Yep...do those in the shop too, with one hand (for at least another couple of weeks anyways) , and a sharpie marker...

[msdesigner]

Any inquiry for TINNED - DRILLED pcb's to : msdesignerpro@gmail.com

I can make also SILKSCREEN ( components mask with black /white color) , if silkscreen file is provided too. 

[Skimask]

Could those drill holes be any LESS consistent?

[msdesigner]

Drilling quality depends, in more than 95 %,  of hole diameter of pad.
So , if usually the drilling it is with 0,7 mm the hole diam. of pad should be 0,72-0,75 for better drilling.

Most of presented pcb's are done it from jpeg's with max 300 dpi and without properly designing of holes.

Attached is 1200dpi (1.6 by 1.3 inch). It passes 8/8 DRC, so surely it shouldn't be a problem for you?

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

Look, there's nothing wrong with what you're doing. Honestly, I hate doing PCBs, I'd much rather be designing them. I'd have no problem using something like this if it's cheap and works. But you need to come up with a proper specification of what you are capable of (see ITEAD, for instance, and then do it better than them because their specs are a pain to read sometimes...), and stop lying (no, you damn well cannot do PC motherboard density and you know it - that or you've never seen a PC motherboard).

And drop the JPEG crap. Take Gerbers and render them yourself. If you insist on using an image format, choose something that supports physical dimensions like SVG, PDF, Postscript, etc, and use something lossless.
