Re: Microscopes for SMD soldering etc
Hi Tron,

? 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:

Re: Microscopes for SMD soldering etc
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.

Re: Microscopes for SMD soldering etc
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?

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:

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:

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 |
Re: Microscopes for SMD soldering etc
@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?

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.

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.

Re: Microscopes for SMD soldering etc
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:?

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 |
Re: USB scope pcb's. compare PCBCAD51 with Kicad
开云体育Circad was the 3rd PCB CAD I played with. It gave me my home brew fat traces desired result BUT its price tag is waaaaaaaay out of my league to buy a current version of it.
As far as OS goes....?? I have a new Win 10?? HP model? 15bs212wm which is a full size laptop with a DVD player and Celeron N4000 CPU 1.1 gHz ... 4 GB RAM with 464GB disk space. This was the cheapest computer I could walk out of Walmart with that was not a CHROMEBOOK.
and
Which is definitely the slowest brand new PC you can buy. So.......... I am not about to compare apples to oranges with the hardware considering adding gigabytes of RAM speeds up anything you have and you can buy refurbed DELL i5? optiplex computers for $150 now
that dwarf Celeron performance.... so forgetting about any kind of SPEED discussion here MY INTEREST IS IN MAKING IT WORK without spending months tripping over "gotchas" and this PCBCAD51 gave me desired results in a little less than an hour while following the "built in"? instructions.

Re: USB scope pcb's.
开云体育Dave, ? I have two and they are just great. My favourite thing with any digital scope is that you can record the info before the trigger. You get a huge display which you can project when giving talks. They are cheap enough to treat as “disposable”. They take up virtually no space in the shack. ? ?

Re: USB scope pcb's. compare PCBCAD51 with Kicad
OK folks......? this is what I think of PCBCAD51
noting I am NOT an electrical engineer that spent a lifetime in CAD programs. I am a hobby tinkerer.... and most definitely an avid PCB homebrewer. #1? The documentation walked me through drawing a schematic with existing library parts then created a ratsnest then autorouted and then made gerber and drill files ?? ========>>>>>>?? IN LESS THAN ONE HOUR OF TIME in front of the computer <<<<<<<<<<======= I just can not impress upon everyone here enough that this definitely IS the CAD for home brewing PCBs. NOTHING I ever used before this PCBCAD51 got me anywhere close the the finish line..GERBER files...? after just an hour of play time. #2 GERBER files are for wussies. Real PCBs are home brewed on your kitchen table with muriatic acid and hydrogen peroxide after doing toner transfer heat pressings. One real issue I have with home brewing PCBs is that I need to trace the toner traces with ink because toner is porous and all the CADs I used made me jump through hoops to get fatter traces ...big enough ...wide enough... for me to actually trace with a sharpie.... BUT?? this PCBCAD51 quickly provided me the solution by allowing me to bump the setting from 20 to 80 in the PCB design screen and fat traces appeared. I'm not selling anything here.... ?? I am just giving my opinion that this software cost less than a beer in my local pub .....and yet.... I got results faster then the zoo I went through tripping over EAGLE and KiCad never getting to learn anything that I could reliably use again. ???? ? |
Re: USB scope pcb's.
I have to say, cresswellavenue (since you don't post with a name), that this does seem a bit like you are only posting this to advertise your software. I see nothing that adds content here, but you keep talking about your software.
You also never explicitly state that it is your software. Concerns of your reasons for posting this are met with dismissive hostility from you. You are on moderated status. -- Steven Greenfield AE7HD |
Re: USB scope pcb's.
Please enlighten us about your REAL purpose of? starting a vague thread about your PC USB scope "project" and the intent of putting your company website on the bottom of your post? Your PC USB scope project and CAD software are both?commercial products that are being sold on your website.
Let's all be adults and try not to circumvent group policies by adding your commercial website link on most of your posts. |
Re: USB scope pcb's. compare PCBCAD51 with Kicad
The speed of drawing is down to the speed of PC and Windows.
The CAD software doesn't draw anything it is all Windows functions.
?
XNA and direct?X frameworks are part of Windows and nothing to do with the CAD software.?
You would need to remove them in Windows control panel.
Removing PCBCAD51 is as easy as deleting PCBCAD51 directory. -- |
