Hi All

 

I am thinking about investing in HD Microscope for PCB inspection and debugging an soldering issues.

 

I have been recommended  Evo Cam 2 .

 

I am wondering is anyone using this type of devices or anything similar?

 

Thanks

Thanks

Regards

DJ

Nice - how much do they go for?

Top Tips:

  1. How to properly post source code - see: https://www.avrfreaks.net/comment... - also how to properly include images/pictures
  2. "Garbage" characters on a serial terminal are (almost?) invariably due to wrong baud rate - see: https://learn.sparkfun.com/tutorials/serial-communication
  3. Wrong baud rate is usually due to not running at the speed you thought; check by blinking a LED to see if you get the speed you expected

About £2000 new,

 

I wondering is there anything which is as good , but much lower in price.

 

My preference is have something connected to monitor.

 

At this price, it is cheaper to get a good camera and mounted on some fixture.

 

 

Thanks

Regards

it's not just about the camera - you'd need a good macro lens, too.

 

I'd doubt that good camera + good macro lens + good fixture is going to be significantly cheaper than the £2k ... ?

 

I'd think doing SMT PCB inspection is going to need more than just a macro lens - you really do need a microscope ?

That was replying to #3 - the comment about using a camera instead:

Remember, a microscope lets you see a 3D stereoscopic image...MUCH better than looing at a flat 2-D LCD.   However, the convenience factor often outweighs this advantage (who wants to squint into a scope for hours, while doing other things, like reading a meter).

 

Perhaps buy a cheapo unit & get some experience, if it is good enough you saved some serious coin.

 

maybe this is all you need for  occasional use a few minutes here & there

I have a little inspection 'scope that I got from Adafruit for around 50 USD. It connects via USB appears as a camera to a computer. It has quite a large focus range and will provide more magnification than is useful for most SMD boards. I use it every once in a while, especially when looking for suspected solder bridges. Its not so useful for whole-board inspection. My contract manufacturer has one that will show all of a good size board with enough magnification to read values on 0805 parts and maybe smaller on a frosted glass "screen"; it has to be really big $$$, however.

 

So, unless you REALLY need whole board display at 50X or better, I'd start with an inexpensive one like I got. Then, after using it a while, evaluate what it is that you really need. The inexpensive one just might be enough.

This is often true when looking at soldering, since a straight top down view often is a poor view....a slightly offset/angled "side" view  can show things better, such as what is going on along the edge walls of pins and components

One of these: https://www.adafruit.com/categor... ?

 

This one's only GBP 25: https://amscope.co.uk/products/1...

The one I got was (I think) PRODUCT ID: 636 . Looks to be a bit more costly now and out of stock. Might not be the same, however as the one shown has more magnification and more pixels than mine. The stand was the weak part but it looks like they have a MUCH better stand available, though a bit pricey. 

 

I did not see anything at AmScope even vaguely like what I got. And, all were pretty expensive, in comparison.

I've used Mantis wide view stereo microscopes and like them: https://kaisertech.co.uk/mantis-... (I had to go through some captcha crap) but...

a) they're not cheap

b) some people don't get on with them, check first

I have a cheap unit from ebay, which connects to a PC. Seems to be a little low resolution webcam, in terms of picture quality.

 

 

 

 

Thanks

That's true, i did have demo of the microscope and it had an option of change the angle , which was very impressive when looking for shorts.

Thanks

The one I got from AdaFruit was pretty good for resolution. The newer one that they now list has a higher resolution camera element though that is not the only contributor to resolution. for any magnification that I can hand-hold, the resolution is quite adequate. I would spring for some kind of good stand as that would improve the usefulness greatly.

Yes, similar.

 

Maybe i was expecting much more out of them.

Thanks
