Microscopes for SMD soldering etc
Anybody using a microscope made for soldering? I finally realized I need to be able to see better, and I will pay for the needed fix. I don't think I want a USB style that has the little monitor/display but rather something like these:
Anyone use one? The only con I see often complained about is if you don't hold your head just right, the view disappears, kind of like with a rifle scope on high power. Thanks |
I have the trinocular version of this scope. I needed the camera for creating YouTube videos. See website.? You are correct on viewing angle you need to see exactly through the center of the eye piece. Also the little fluorescent light isn't bright enough under higher mag so splurge for the led version. The other issue you'll have is solder fumes if you're working on a board. Get a good fume extractor too. You can see the quality of the view in some of my videos to give you an idea what you'll see.? 73! Mark KA6WKE Website:?

Make sure that if you buy one used, that it's not made for chip examination, and that the working distance between the work and the lens is fairly large.? Chip microscopes have almost no working distance. You'll want a good fan as well. As for the "hold your head just right, mine doesn't seem to have that problem.

and you will be surprised by the number of solutions you CAN afford. I have bought them in the past for children and have found that many of the dirt cheap binocular microscopes... $35 ..... have no problem at all being the right magnification and distance for SMD free hand soldering. The ONLY? "gotcha" I found was that some binocular microscopes have a child sized PUPILLARY DISTANCE (PD) .....? the distance between your two pupals and no way to adjust that distance. So shop carefully to learn that distance. I've been using this one for many years...... they sell now for $87 20X Binocular Stereo Microscope SKU: SE204-A and I suspect this is just as good for $53 AMSCOPE 20X Portable Sharp Binocular Stereo Microscope LED PCB Repair Dissecting There are huge price differences for these microscopes and I don't know about you guys but so far I have not been disappointed by any of the cheap binocular microscopes.

@Dave, I too went through the process of attempting to resolve the problem of soldering SMD components. I tried a variety of USB Microscopes because they were inexpensive while the vendors were promising performance that simply wasn't good enough. However, microscope also have their foibles. I came to find that its best to call the microscope company and tell'm your budget and your goal. If they are an authentic company, they'll help you make the correct choice. If you are just soldering a few 1206 and 806s here and there, well its fairly easy to solder these by hand using a temperature controlled pencile soldering iron. If however, you are doing a bunch of boards with many different sized SMDs, I recommend ya take the extra effort to fabricate an SMD oven. The ovens are simple to make and are VERY easy and effective. I used a Black & Decker 1200 Watt InfraWave toaster oven which have low mass 'crystal' heater elements that exhibit low thermal inertia. Check out this inexpensive SMD oven controller and homebrew website. tron nee On Thu, Oct 31, 2019 at 5:24 PM Dave <theschemer@...> wrote: Anybody using a microscope made for soldering?

I use a Mantis Elite at work every day for soldering. It resolves exactly what you mentioned, that the view disappears, because it has very wide field eyepiece area (you look into a single "screen"). Of course it costs real money, but I wouldn't want to miss it. You definitely want an optical stereo microscope, at least if both of your eyes are still somewhat functional. A 2D digital image does not compare for soldering. ST On Fri, Nov 1, 2019 at 1:24 AM Dave <theschemer@...> wrote: Anybody using a microscope made for soldering? I finally realized I need |

The question is, have you tried the more expensive ones? I've definitely been burned, I bought a cheap one that looked exactly like a Meiji I have, and the picture quality is absolute crap by comparison. I don't think Amscope is bad from what I have heard, but have never tried one myself. ST On Fri, Nov 1, 2019 at 3:47 AM Rob via Groups.Io <roomberg=[email protected]> wrote:

The built in light is a bit rubbish so you'll need a ring light as well <> The base is not really heavy enough so it is best to clamp it down but otherwise it works reasonably well. Forget the included 20x lenses - they are too powerful for PCB work. You do need to hold your head just right but that goes for pretty much any optical microscope. You get used to it and having binocular vision makes such a difference. Les On 01/11/2019 00:24, Dave wrote:

I use a dissecting microscope from Lakeland Microscopes. Their seems to be something wrong with their website.

Thanks for the info. I checked out your website and looked at the view. Don't know if I need the camera but I guess it wouldn't hurt to have that option. I read that the camera's vie isn't in the same place as the binoculars view. Is that true?

Hi Harvey, how's it going? I have done a crash course yesterday and learned from my early findings that I need distance to work with plenty of access. And that a 0.5 objective lens for a wider view is a good thing to have. I will be searching for a while but not too long. I don't want to have to buy this thing twice after making the wrong decision first.

? Thanks for the info. I looked at a few inexpensive ones but after reading the reviews it seems the more experienced people said a 0.5 objective lens was a must for being able to see more of the board, and that 20x was useless for the particular brand and model they were referring to. I don't mind paying up a little more for a good microscope but I am talking $750 max or somewhere around there. I must tell everybody I am just a hobbyist with a desire to learn so my projects have a professional look to them and that I can be proud of my work. Also, thanks for the link to that reflow oven. I am a man of many interests and projects so I may actually make one of those. I have never used lead free solder but I assume one could use 60/40 regular solder with a temp change. How many hours does it really take to reflow solder a small pcb? Thanks, Dave On 10/31/2019 10:57 PM, tron eee wrote:

开云体育Hi Stefan, ? That Mantis looks great but way out of my price range. My eyes
are fairly functional but I am far-sighted and use reading
glasses. Both eyes are the same so figure 20-20 but far-sighted.
By the way, can you wear reading glasses when using a microscope
or does the scope take away that problem and you just dial it in?
I did enough research not to want a digital microscope for various
reasons. Thanks, On 10/31/2019 11:13 PM, stefan_trethan

? I thought your name was familiar. You are the SheetCam guy. :) I looked at this particular scope initially when I started my research but after more research it seems a 0.5 objective lens would be much better. Is one available for it? Also, thanks for the links and the one to the LED light too. Dave On 11/1/2019 4:36 AM, Les Newell wrote:

? My PD is 62 as I measured once to get some reading glasses online, so I could use the lenses in an Occulus Rift. I checked out these scopes and they get good reviews. It gives me something to think about. I just know I read that a 0.5 objective lens really makes a big difference on how much (FOV) you can see. And some manufacturers may or may not offer that lens as an option. If I replied twice it is because I didn't see a returned message and I have been replying to all that commented.

Dave, You are correct, the view with the camera isn't exactly what you'll see through the eye pieces. The problem is that sliding barrel that's used to attach the camera to the body. I've purchased one of these to fix that problem: . There are plenty of times during a video where I'm working away on a board that's fine in scope view but it's out of the scene with the camera. If you're going the route of using a camera, be sure to get a scope that's Simulview or something like that. Some of the lower end scopes with a camera are listed as trinocular but what they have is a lever that flips the image from an eyepiece to the camera leaving you with just one eye to view what you're working on. 73!

I bought the same scope several years ago and am totally addicted to it.?? With the scope I can do any SMT work I need to do, without it was endless frustration.? I find myself using it whenever I need to take a close look at something tiny, and intend to add the video camera option.
You'll develop your own style but having real optics in my opinion greatly facilitates the learning process as the mapping between eye and hand is direct.?? You'll probably need to rig up a suitable work stand to position the board in the field of view. I made one out of scrap wood with a shallow lip around the perimeter that helps to keep parts from flying too far (sometimes) and which is easy to rotate to get the angle I prefer for hand soldering. I also have one of the $40 video scopes with a built-in LCD monitor and I could get by with it if I had to, but I much prefer real optics. 73, Bob W9RAN |
I've got several scenarios that I use.? One is that I need to have a field of view big enough to handle a 20x20 144 pin TQFP. That's needed to center and sit on pins.

Secondly, I need as much of a closeup as possible needed for each individual (or group of 5) pins.? Intermediate settings do individual parts. You do want the closeup if at all possible to look for shorts (don't ask). Ring lights are very very good, and I'd recommend them.? Mine's fiber optics and I use an auxiliary side light.? I'll have to get an LED replacement when the bulb goes or find another bulb (may be easy).? Using it on the lowest setting gives me the proverbial immortal light bulb (a good thing). Mine are american optical made, quite used.? A boom stand is an excellent idea if you can find one. That, and the metcal tips (oddly enough, the finest tip is not all that useful), do well. I'm busy putting together PC boards and writing (rewriting) low level graphics drivers at the moment. Harvey On 11/1/2019 9:17 AM, Dave wrote:

With both eyes the same you don't really need to wear the reading glasses, since you can probably just adjust the focus of the microscope. You may still want to though, if you need the glasses for other stuff and don't want to take them off all the time. They make special glasses compatible eyepieces for that (higher focal plane, usually have a glasses symbol or H etched into them). Even if one eye needs a different prescription most microscopes allow you to dial in a spherical correction. I have never seen an eyepiece with cylinder correction, but would very much expect they exist as a specialty item.? A good quality stereo microscope can offer the same or better vision as the mantis.? It's just more comfortable and efficient to use.? ST On Fri, Nov 1, 2019 at 2:32 PM Dave <theschemer@...> wrote:
