Refined desoldering station ZD-915

stepawel  Cool? (+86)


Hello.
I would like to present the desoldering station ZD-915 that I have made. The modernization was done already in the first week after buying the device. The condenser, which exploded inside the station, contributed to this. I found that sending back the equipment for warranty repair did not make much sense and I got to work.

There were a few inconveniences that irritated me in the original layout:
- continuously working fan;
- switching the pump motor directly through the miniature switch in the gun and thus - fast burning of its contacts;
- a one-plate rectifier for supplying this motor;
- badly soldered wires and often too small cross-section.

In my project I eliminated the above-mentioned disadvantages. I used 60N06 transistors to control the heater and the motor, which means there is a considerable power reserve. The radiator to which they are screwed does not even heat up during operation.
The fan's operation depends on the temperature of the rectifier bridge, which already has a larger radiator than the one in the picture. The fan itself was replaced with a lateral blow.

The device works without reservations for a year.
I think that although the project itself is very simple, it will be useful to someone who wants to change their desoldering bit better. The PCB has been designed to fit into the housings in the casing and does not affect other components of the device. I could not resist :) entire :) case
Greetings.

During the modification, did you do a pattern of what it was? How did you do a new PCB, I mean the program or schematic> pcb or did it without a schematic. I'm asking because I have such a station.... [Read more]

I made the PCB myself by a thermal transfer, later the tile was covered with rosin. PCB will be available as soon as I find :) Will be shared with the list of elements. I usually only do tiles, I have... [Read more]

Ok, I will wait. Is there a bone to operate the display on this board? How is it made? [Read more]

stepawel 18 May 2011 20:29

The display together with the heater control (without the executive system) is on one front plate. I've made an executive layout that I think deserved to be changed. The PCB project has already... [Read more]

I have a question, what colleague did the compressor use? Is it very loud? If some quinol looks like that to me then I have to admit it's a muddy job. I have a similar compressor in Hot Air PT968.... [Read more]

I have not changed the compressor in this device. I admit, his work is very annoying. Often, it was the instinct to make the house revolt. :) Some time ago I thought about inserting something quieter... [Read more]

In total, you have done what you need immediately after the purchase. The case of a compressor in a desoldering machine looks a bit hopeless because it has to be a membrane, i.e. one that can cope with... [Read more]

Nice thing with this modification. I have been working for more than 1 year on the original QUICK 706 station and have so far been quiet and nice. Some seem to be walking loudly, according to the instructions... [Read more]

Budego bodzio667 you can use a central compressor with a pneumatic lock with a car, for example, the Audi A4 is small and silent, after that the high suction and discharge power I own in the station after... [Read more]

And you had the opportunity to compare this car compressor with the original desoldering station from the topic? How is the noise issue? The second question is how long it can work, because in cars its... [Read more]

electro 19 May 2011 13:24

I also use the compressor from the central VW lock. The compressor reaches -0.9-1 Bara, so more than the factory, eg weller. As for working time, it is impossible to get used as a dilator. For sure it... [Read more]

On All..o they are different, for example with a 3-pin connector and those with a connector probably 8 or more terminals. In the car industry, I know little about the issue and hence the question: why... [Read more]

Because in the casing the compressor is also often the whole logic of the central lock [Read more]

Do not bother you clogging a tin container? I immediately replaced him with a desoldering machine for a container from Denon SC-7000. All you need to do is cut it down a bit. Now much less often you have... [Read more]

The station was painted with car spray paint, using a primer paint, also in a spray. Probably there will be reservations that such a thing is not very resistant to scratches, and in my opinion you just... [Read more]

krzysztofh 19 May 2011 21:10

Can you give some photo with this container? I even created a thread about the clogged container, but few people spoke. In the end I do so that after cleaning I lightly spray the WD40 spring or silicone... [Read more]

Syntax 19 May 2011 21:26

Containers from Denon SC-7000 can be bought for about PLN 30 on Renex That's how it looked like it was new: http://multisort.pl/u/a/2/6/a26c51dff17b5d8f897c2173409f8953/320x_SOL-SC7000_WF.jpg... [Read more]

Syntax, can you tell what the tin stops in this filter? Is there something like a polymer sieve? [Read more]

krzysztofh 20 May 2011 07:11

Exactly. What is the baffle in the center of the sleeve before the sponge or nonwoven filter? Does it not block the air flow tin after a few aspirations? [Read more]
