$2 for 10 boards
$9 for stencil
$25 for DHL
Currently probably the cheapest on the market.
3 working days between order and shipping.
Zero flaws or problems even with the lowest possible clearances.
Absolutely worth trying!
Some time ago I was looking for a new PCB service. After quite a long and astute investigation I bumped into very interesting offer.
„JLPCB is the largest PCB prototype enterprise in China”.
After some small problems with registration, which were solved really quickly by their support team, I was finally able to place my order.
I discovered SeeedStudio some time ago, since the company is pretty active in the internet (facebook, own wiki, some projects on github). Last month they introduced PCB manufacturing services, called „SeeedStudio Fusion Services”
I decided to give it a try, because the website looked pretty neat and modern. They also provided (see below) a little bit better specs than the others.
For now, I have places three orders there, all with the same specification:
- 2 layers
- 10cm x 10cm
- 10 pcs
- 1.6mm thick
- 1oz/ft2 = 35um
- Stencil: frameless
In one of my orders I also used free „panelization”. They allow to duplicate the same layout over one board – I had 4x 4.5cm x 4.5cm over one 10cm x 10cm piece.
Update 05.12.16. The dirtypcbs site looks pretty new, it is now the same as http://dangerousprototypes.com/store
- 2 layers
- 10cm x 10 cm
- 10 pieces
- PCB Thickness: 1.6mm
- Surface finish: HASA
- Solder mask color: Green (all with the same price)
- No sub-boards
- 100% E-Test
- Stencil – frameless 13cm x 21cm
A simple list of lowest prices of STM32 MCUs on Aliexpress, captured 2016-10-02.
As input I used list of 666 ACTIVE products on ST website. Items not available on Aliexpress are hidden.
For preview only 😉
Some sensors MAY actually work. This does not discard what i wrote before (I tested them all), but: For some reason some of the sensors gives invalid response to ‚Power supply’ command. They always respond as they are parasite-powered. Some devices (ex. mine) do check that and reported them as invalid. However I tested all ‚Invalid’ with osciloscope. Some of them gave some response, so i took the deeper test.
If you’re planning to order cheap DS18B20 sensors from AliExpress – keep in mind that irrationally low price (less than $0.8 / pc) smells really fishy.
Manufacturer price for 1k is $1.18.
A few days ago I was building rack 19″ server based on AMD Athlon 5350 CPU. The main goal was to create a hardware set that will operate on wide supply voltage ranges (48V, 24V, 19V) and will be power efficient.
I decided to take a look at quite cheap AMD AM1 Athlon APU with TDP said to be 25W.
