Price
JD.com purchased and participated in the event of full k minus 100. It used a plus user-60 coupon.
Actually paid 2,990 yuan.
2. Locked the day before yesterday, paid yesterday, arrived today, the outer box is three layers of corrugated paper, thin, but fortunately complete.
3. Box
4. Say
5. Things
6. Iron chrysanthemum
7. Small light bulb, 82mm, can't afford to buy a filter for naked streaks for a while
8. Moderate eyes
9. Zoom ring
10. Take a test on the 11 side, the equipment is Canon EOS 60D, ios400, F2.8, 1/8000s
to sum up:
Advantages: Wide enough (photo shoot, shoot mountain weapon), the volume can endure (a lot lighter than the previous Tamron 1750), focus fast (and the sound is very light), 11 full open sharpness available, the color is currently satisfied (taken not much)
Disadvantages: The 20-wide open-end is poor (look completely at luck), in addition, purple fringe is slightly more serious, do not know if it is an example.
Cost-effective: The price of 2990 is definitely worth, after all, there is a f2.8 and 11 available. For me personally, it is very likely that I will only take this one head when traveling. However, it is not recommended to take a picture of a girl (beating a thick leg to care for the life of a dog). Portraits are not its specialty.
PCB Assembly
PCB Assemble is not PCB plus components loading,but also the technologies.including PCB design,manufacturing,components ,process.Finally,we must have a strong understanding of the final product.That is why we asked you to supply samples or photos if any.
Storm Circuits is a one-stop solution for all circuit board services so we are often entrenched with the PCB fabrication process from design to assembly. Through our strong network of well-proven circuit assembly and manufacturing partners,we can provide the most advanced and nearly limitless capabilities for your prototype or production PCB application. Save yourself the trouble that comes with the procurement process and dealing with multiple components vendors. Our experts will find you the best parts for your final product.
What information we need for PCB assemble?
1.PCB Gerber file,or your design file.
2.BOM in excel,an example for you to reference.
I3.f any,please send a sample or final product photos. 3D view is also very helpful.
4.Assemble drawing.Some in PCB file,some not.
5.RoHS or not.
what is QTY you need.
Since PCBA project is much more complex than PCB manufacturing,your inquiry need about 3-4 days to reply with quotation,fastest 1 day to you .and standard lead time for PCBA is 3-4 weeks,2 weeks for express prototyping.
We purchase 99% of the parts from oversea to guarantee the components quality.this is the most important for your product.
