EEVblog #241 – Circuit Labs PCBs from New ZealandPosted on February 2nd, 2012 17 comments
Many people asked to see the PSU PCB’s from Circuit Labs in New Zealand.
Here is an in-depth look, compared with the same board from ITEAD Studios
The Circuit Labs silkscreen might be a photosensitive one – applied the same way soldermask is. Was looking for soldermask on eBay a few months ago, and came upon some jars specifically for labelling use.
It would also explain both the more transparent nature as well as the perfectly smooth edges – this is not an old-fashioned silkscreen process, at the very least. The dot-matrix effect you see on the chinese boards is due to the mesh used to create the screen for the printing.
Nice boards, by the way.
Hiya Dave, great to see some NZ stuff, I live in NZ and didn’t know about Circuit Labs.. got all of our boards made in China, definitely check them out for the next run.
Can’t wait for the power supply kit, looks awesome
I find that my flatbed scanner is the best way to get high-res images of circuit boards. Also, since you know the scan resolution, you can measure features as well.
Also, note that holes in HASL treated boards may be smaller diameter as the HASL plates the inside of the holes as well. Manufacturers are supposed to account for that, though, but they might always use the bigger drill so they don’t have to have option-specific drill adjustments. Also, some manufacturers have a limited set of drills and will round up, so the fact that one board’s holes were bigger than the other might have been a coincidence of available tool sizes.
I love the EEVBlog – I’ve probably learned more about electrical/electronics engineering from you in the last few months than I did while getting my electrical engineering degree!
In this video, you mention Murphy yet again. I thought I would share MY favorite – “O’Malley’s Law”.
O’Malley’s law states: “Murphy was an optimist…”
Keep up the good work, and best of luck to you!
Hi Dave, solid work as always! I just wanted to point out that iTead studios also offer a faster DHL shipping alternative, with which I received my boards after a week to Sweden.
Love your blog, keep up the good work!
Great to see that there are some local pcb fabs with good quality. Hard come by these. On the other hand the old ucurrent looks a bit better (at least on camera) – the red mask is a bit more suitable for the panel.
With all due respect, that was lot of useless nit-picking for a circuit board that will boxed in a container anyway. I am sorry to say that I felt like I really wasted my 15 minutes watching it. I have a lot of respect for EEVBlog to walk away without mentioning this.
P.S. I’m not Chinese and don’t have anything against New Zealand.
My husband is a PCB engineer. We are relocating to New zealand soon but the problem is we cant find a job there. can you guys give us a list of recruting companies name?
my email address is firstname.lastname@example.org
thanks in advance.
