PCBcart has really snagged my attention because they offer lots of options (solder mask colors, copper weights, etc). Does anybody know if the "one-time tooling fee" is really one-time, or is that applied to each order?

I have only used them a couple of times with different artwork, I think it is really "one-time tooling fee" but could not rule out a small set up fee, other manufaturers do.

It's strange no one has ever made a summary of PCB manufacturers and rated them like 1/10, 2 out of 10...

Or is there something like that?

I must say... strange no one has totally bashed any supplier, or is all the big PCB manufactures that good?

jsiei97: Well, my teacher was really pissed of with Amset :-) . I'd guess that it's an evolutionary thing. If you make crappy boards, the word gets out more quickly than if you made good boards. Without customers, you die of moneyhunger.

toalan: Could you please scan (or use a digital camera) a card from the MyroPCB-batch? Or perhaps one from Myro and one from Gold Phoenix?
Could be great for others to compare two different suppliers.

I've ordered PCB from Olimex before:

But this time I ordered from MyroPCB, the reasons are better price at Myro with big order and smaller vias.
We'll see how those boards turn out. If they are ok and I get the funding an order will be placed on assembly for about 100 new boards.

Thanks

I just placed an order for a few 'fancy' boards from pcbcart. One small serie is black with black mate and gold immersion (I resisted the drive to get red silkscreen :D), the other blue, with 1.0mm thickness...
One of them is a panel too and has some round corners, I wonder how the depanelization will handle that...

I got my first MyroPCB-order yesterday. This evening I will go and solder the first boards. Its 55x18 mm, avrmega168 + CAN.

The result is really sweet, well see if they work :)

@arune: Nice looking boards.

I've used MyroPCB for about 6 different orders now and have been extremely happy with both quality, price, and delivery time. The $50 NRE goes away after the first order on a particular board. I found that there's no price difference between two week and 1 week turn times so I always select 1 week turn time now.

I just got a quote from Myro for assembly + parts supply for 200 of my boards. I was very happy with the quote, their prices for components are very reasonable.

SMD resistors are 1 cent USD
SMD ceramic 10 nf caps are 6 cents USD
SMD 5 volt regulator is 34 cents USD
SMD lm358 is 31 cents

Those are the component prices for the popular components my board has. I know everyone is going to want to know the price for AVR, sorry I am not using AVR for this board.

For Assembly, it looks like they charged me 0.12 cents per smd solder. However it looks like there is a setup fee of $365 ontop of the 0.12 cents per smd solder. I assume that on my 2nd order most of the setup fees would be waved.

All together it looks like the total costs per unit is ~11 USD, not including shipping, I was expecting something closer to 15 USD so I am very happy.

I just got back 600 dollars worth of pcb from myro and they look good.

I think myro should know that you guys heard of them through avrfreaks, would be nice if they became an advertiser and perhaps had a special for us. So guys let them know in your email that avrfreaks.net is where you found out about them.

Regards,

Alan To

Hi all,

I have used one time PCBCart in China, and I get no issues with, and they are very fast.

please found here the link to my project in a French forum, some pictures available.

Does myropcb allow panelizing or multiple designs on a single board for their prototype service? I have a need to create at least 20 small boards for one project, but most places don't allow panelizing on prototypes without charging a hefty fee on top of the prototype cost.

Just got a prototype panel from PCBCART, 4 designs 12 pcbs from smallish to largish. ~$100.00 one off set up fee I think.

This lot they did because I think I clicked on single boards but last time they all were in a big blob, easily separated though. oh alright here is one of them :)
Edit posted a better photo scan.

I received mine, with the 'fancy' options (gold pads, blue and black finish, 1.2mm thickness) and they look gorgeous.
The .pdf I posted a few daysago was a 'panel' and they depanelized them, including the round corners!

Also, it seems the gold finish is a lot more 'precise' than the tinned finish, I have a few tiny connectors (.5mm) and the pads are very nice and extremely regular...

I'll do a high res scan tonight, before I crack up the solder paste :D

Got about 100 largish boards last year with gold finish form them too (gearing up for lead free on some products :( yuck ) and the boards look impressive, I had a hard time handing them over to the board stuffers :lol: however I was told by them that it isn't really gold (could have fooled me) but some sort of copper..whatever.. They had to increase the solder bath's temp a little to work with them as I understand.

I know what you mean, they look too good to put some filthy components on ! :D (almost)
I'm not entirely sure of the 'impact' of the 'gold' finish, but it certainly looks a lot more 'precise'; I'll see how the reflow goes. Maybe the normal tining is just naturally thicker thus the impression of less precision.

Be careful with MyroPCB. They are dirt cheap, and some of my stuffed boards reflect the price. Parts missing, backwards, etc...

Those blue/black PCBs look really Elektor-ish :D

I used PCB-Pool twice now; received a 6 layer prototype a few days ago. Looks good, but I don't really like the soldermask they use, it's too shiny. I prefer a slightly duller finish.

Their customer service is excellent; received a reply to an email within an hour.

I'm wondering... is electrical testing done after manufacture, or before the soldermask is applied? By accident, one footprint got soldermask on the pads, and the E/T came out fine. While it's impossible to solder components onto these covered pads :D Or are the probes so sharp they puncture through the mask?

Buserror, I like that ribbon connector you used. I have been looking for them (a little), and I have not found them. I must not be looking with the right name. What is the name and manufacturer of that connector you used?

Spamiam, RS components in the UK have them: Look for 'FFC Cable Assembly, 0.5mm'. They're a Molex part.

Actualy this is the Cheap non-molex equivalent at farnells. Had no problem with them tho. Maybe they'll breakdown after 10000 activation instead of 10000000 or something :D
I can post the Eagle footprint too if you like

I've recently ordered/received assembled cards from MyroPCB and I can higly recommend them.

It's the same PCB as I've ordered from them earlier (see my previous posts in this thread.)
The order was for 120 cards of the same type, about 50x20mm, 4 ICs (one avrmega168), xtal, 16 0603-components, 2 diodes. Only SMD.
The result is very good, soo far I've done a basic test on 33 of them and no issues yet. (Since the card is very simple the basic test covers most of the functionality.)

Price:
http://spreadsheets.google.com/p...
As you can see, the price for one time costs is 160+85 so for the next order prices for each unit will go down about 2$/pcs depending on order size.
I'd say they are very cheap if you can order a high amount of units.

www.EzPCB.com. We had all our boards made by them, reasonable price for good quality. They offer free components (res, cap, connectors) for prototyping boards and even solder one for free!

I visit their website some days before, found it's updated. Now it accept online payment by paypal. The Ez-Proto service is the most cost effective PCB fab service I've ever seen, only $50 for 5pcs 4"x4", full featured boards. Do forget it's worldwide free shipping. Here's the ez-proto: http://www.ezpcb.com/ezpcbweb3/o...

It seems all customer likes online quoting, online ordering,maybe our company should change website accoring to customer need.

JayJay,

No the probes are not sharp enough to do that kind of probing.

Sometimes the pad is a mid point pad and the electrical test is may be configured for end points test only ( logic being if there is connectivity between ends of nets... why probe each nd every mid point)

At other times the test may be less than perfect.
Flying probe testers use a number of techniques to optimise the test time.
The operator may do a charge rise time test only to check for sufficient copper area in a net.In which case the masked pad probably would not be picked up by the tester.

Obscured features may not necessarily be picked up by electrical test
