852D+ and Microscope
« on: March 14, 2019, 02:48:35 pm »
I have the 852D+ hot air station and having problems trying to use the hot air with my microscope.

I have a 30x microscope, and, in order to see the IC on a PCB, I need to position the microscope a short distance from the PCB. This causes a lack of space hindering the ability to move the hot air pencil evenly around the IC.

Does anyone have a solution on this issue and/or suggest a USB scope that can sit further away from the PCB, but while focusing close?

45 degree air nozzles for your station.  A lot of the video bloggers that do hot air rework use them under their microscopes.

The optics of long arm microscopes are usually designed to provide a reasonable working distance between the object and the objective lens:



Used long arm microscopes do appear on eBay, from time to time, and occasionally sell for a low amount.

I saw one USB scope for about $22 (???) and then found someone reviewing it on YouTube. Unfortunately the scope needed to be within inches of the object.

As for curved heads, I don't believe the 852D has any curved head accessories; just straight.

Do you really need to have 30X magnification?  I have an Indian made scope that goes from 10x to 40x.  Even at 10x, it was too much magnification, so I put a 0.5x Barrow lens.  It's about perfect in terms of visibility and ability to put in soldering irons.  It is also nice because the optical element is somewhat shielded from heat.

It's the scope I have - not much of a choice.

I linked to some 45 degree nozzles in my post above that say they'll fit an 852D LINK.  If the nozzle is too long, you can use a pipe cutter LINK to cut it down to the desired length.

Would you mind measuring the hot air nozzle of your station and posting what the diameter is?  I'd like to buy some 45 degree nozzles for my Quick 857DW+ but I don't see any listed for that station and am hoping the 852D+ is the same size. Thanks.

Sorry, I didn't realize that was a link. I'll take some measurements this weekend and let you know. As for 45 degree nozzles, I think it may help; and possibly be a solution. Ideally I was looking for an affordable USB scope that I could place further away and zoom in allowing me an open area to work.

Is the clamp that attaches to the microscope a standard part? My microscope has a pair of threaded fixing holes.

A searchable name for ebay?

My microscope doesn't have any holes or an area to mount anything; and unfortunately no hole for a light.

The top has a knob for zooming, the sides have a knob for manually moving the scope vertically. So I need to have an external light aiming on the object which hinders even further the ability to have free room around the top of the object.

So ideally, a separate USB microscope fixed further than the object, but with enough zooming capabilities to see small objects.

What microscope do you have?  Can't you buy new optic pieces for your microscope?
