If you plan on ANY rework (removing parts from a scrap rig or parts you soldered in in error) forget the solder sucker in that set.  I have tried many different ones over the years and found them not effective.  If you don't want to invest in a real solder vacuum removal device get some solder wick of different sizes and a bottle of rosin flux.  Dip the wick in the flux, heat it up by the part you are removing and little by little the wick actually wicks up the solder until it is 95% removed. Then with a little heat on the remaining legs of whatever you are removing you can lift it off or out of the holes in the board.  I have been doing that for years with great success.  Then remove the excess flux with 91% rubbing alcohol available at any drug store.

Have fun.

No way I was going to leave this alone…

First advice, don’t listen to any ONE on this list, nor or any other list of any nature…never one….try it yourself…try multiple ways, and stick with what works for you.

So, with that said, here’s mine…

Get a temperature controlled solder station…that doesn’t mean 4 detents with 4 temps….that means 0 degrees to 700+ F with ability to pick your temp….as you always want lowest temperature that will work for the job….similar to radio….lowest watts out needed to do the job…but, with ability just like radio….to blast it when needed…and fast….

I have a solder station that is a replacement for the exact same model….one stolen back in 1995 (along with scope, NTSC generator, freq counter….everything except my fluke….I am still using it daily….from MCM (called something different now)….last I checked they started selling it again, as customers complained when it was discontinued. Cost when I checked last was about $70.  Tips got good back in the 90’s if you treat them right….I am using a tip from 1995 daily….very fine conical tip….will do almost anything….just slide up the barrel…

I recently bought one of these 2 in one hot air and solder rework stations….862D+….got mine for $49….most go from 60 to 65.  I broke the soldering iron (shame it worked great, but when it fell out the car, it snapped in half), found out the element isn’t ceramic, but is nichrome….and first replacement isn’t right)  the hot air works great, temperature tracks with a harbor freight thermocouple (so you know it has to be good)….my little builders group has been playing with this with manual pick and place, that is drivable….use a bicycle pump shell for z-axis, and steer with the T-handle, vacuum is a Tetra-whisper aquarium pump, and add a $30 USB camera (was daily special)…..a tube of MG solder paste, took off the nozzle and replace with smaller diameter nozzle off of empty flux refill bottle, and then used another of those empty bottle nozzles for the syringe pick up tube (luer lock) …..

if you want to see what we are doing go to Facebook Group: wecanhams 

this is latest with hot air/with no rework with pencil:


this one is a short video of the pick and place in action….with USB camera…I have made some improvements like 2 point clamps on the red tube and a recessed pick area...


Important to have a way to monitor the board temperature if you are using hot air or a reflow oven, and run a recognized heat profile…takes a little practice...

<28958739_2035568706459771_6244662275475505152_o.jpeg>

the latest hot air placement with no rework, paste was laid down with syringe, a little dab will do ya...

<29244570_2041142825902359_574099065751470080_o.jpeg>

the rework station bolted down, before accessories added to new home. We are working with a lot of junk and recycled, up cycled junk.

I don't do a lot of SMD projects and so I don't use a mask just manually apply the solder paste from a syringe that the paste came in. My advice is that you can't have too small a nozzle. In the attached photo I use the cone shaped one because the black one is too big. You'd be surprised how little paste you need before you make a big mess! My source for paste isn't available any more so don't have any suggestions but I'm sure it's not hard to find sources.

How do you apply the paste? I dont have a way to create a mask for a pcb. You also make a good point. If you have a heat gun you can use shrink wrap. Thats a great reason to get a hot air rework station with an iron.

Re: Finally finished boxing up my uBitX #ubitx

Hi Howard,
The 2073 seems to beworking fine, good audio and plenty of volume, I've run it turned all the way up to drive the NesCAF, since you lose some volume as you crank down the bandwidth, and it's been fine, no problems at all.
Haven't done a pop fix yet, still mulling over the options. In the mean time I use the old trick of putting the phones just off the ear

Re: Finally finished boxing up my uBitX #ubitx

Hi Tim,
Just left it as is. I was thinking about copper tape on the top and sides, but given the way the board sits and the way the box goes together, decided it was more trouble that it would be worth. So far I haven't noticed any downside to not having the shielding.

Re: Finally finished boxing up my uBitX #ubitx

Michael Aiello
 

Hey Joel, 

If you have a socket on the board I would definitely switch it out. Sound quality is really very good, although I never actually heard the rig with the 2822 so it's not really a comparison. If the chip is soldered in I don't know if it would be worth the bother, especially if you have everything working now.
Thinking about doing a pop fix but haven't picked one yet.

Re: VE1BWV audio pop fix - lost my sidetone

K4LXY
 

 I did try moving the circuit to the other side of R70, and also replacing R70 with 1K and 10K. Unfortunately none of this worked to bring the sidetone back.
Thanks
Any other suggestions?
Thanks

I've used Seeed Studio (Fusion) for all of my boards and I think their quality is excellent. They are not cheap, but I like that I can drop-ship the boards if needed and they do DHL shipping if I'm in a hurry. Usually it takes about a week to get them to produce the PCB's.

That looks like a great kit for the price. I spent more than that for just
a Weller SP40NK 40W soldering iron (with 3 tips) from the local Home
Depot. Of course, I already had all the other things on-hand, such as
third-hand, brass tip cleaner, Kester 63/37 rosin core solder, desoldering
wick, soldering iron stand, temperature controller, and so forth.

Recently, I got into SMD soldering, so I added a hot-air gun,
a toaster oven (re-purposed as a reflow oven), and a syringe of solder
paste.

If you are new to soldering electronics, be aware that there are practice
kits available for both through-hole and SMD soldering practice. These
kits come with an etched PCB, as well as all the components. Usually,
they will also be a functional circuit of some sort or another, so you can
test to see if you have done a good soldering job, or not.

Good lighting, a clean work area, and a magnifying glass or loupe to
inspect your work as you build your kit are also must-haves.

Good Luck with your new Soldering Station!

Re: Solving problem with when plugging in a headphone causing a shorted to ground of C77 470uF to ground and may damage U1 TDA2822

Best bet is to plug in mic and headphones & antenna before you turn on power.

If you don't use a  speaker  with your uBITx and use only a headphone. best idea is to add a 1K resistor to the negative lead of C77 (470uF capacitor) to charge the capacitor slowly when  first power up. Now when you insert the headphone ,any accidental shorting of the sleeve and tip to ground will not create a surge  from the U1 TDA2822 since  c77 is already charged by the 1K resistor. this will prevent a loud pop on your headphone as well as possible damage to the audio amp chip.

Ian,
I am having difficulties trying to get uBITX Mgr v0.2 to read from UBITX.  I've tried the resisitor solution and the capacitor solution with no data showing in Manager.  The display does show db:40000000 and second line the standard LSB and Frequency.
any suggestions (from anyone would be appreciated)

Re: Dirt cheap uBitx case #ubitx

N1AFF - formerly KB1JPW
 

Thanks!  Ouch, always when you think you're getting close to done... 

I've added the rj45 jack for my spare handheld mic along with a mini usb port on the back. I still need to wire up the up/down buttons off the jack.


I left the front plate with the original jacks in case I want to ever use them again.  If I don't I'll end up creating a new faceplate and have the rj45 jack directly on the front.

There is now a 1" fan in the top along with a 2" speaker.  I ended up replacing the green screen with the blue and it's quite a bit easier on the eyes.  The case was painted hammered black on the top and bottom pieces. The front and back plates got coated in hammered silver.  I wanted a bit of an old-school vibe with the hammered paint.  



I realized I never gave the case dimensions - it's 7"wide x 6.5" long and 3" tall ( ~17.5 cm x 16 cm x 7 cm)
When I make it back to the office I'll be printing up laser water slide decals for some last minute embellishments and labeling. 
At this point I'm not sure I'd do another scratch built and recycled case due to the effort and extra time.   (lies, all lies) I definitely spent more time and labor costs building and assembling than I would have if I bought a pre-made case. I've still got some more cable management to do on the inside but had to throw it all together for a quick distraction.  

a Little Gun Shy #ubitx-help #ubitx

So,
My uBITX is working fine, so I should just leave it alone...Of Course not..
1.  Before I start mucking with the sketch, I want to be able to get it back to what came with the rig.
so went to https://github.com/afarhan/ubitx
downloaded the zip as usual. 
Inside there is the ubitx_20 folder the .ino with the ubitx_20, is, I assume that is what should be uploaded to the nano?
Is the CAT function an original part of the sketch that will get loaded with the ubitx_20..that i haven't tried to use? as I would like to have HRD control of the uBITX..
ugg..
 
Must not be thinking this through, Allard's changes on my 40 seemed to be easy enough.
quick answer would be appreciated.

The KD8CEC Memory Manager requires mods to the stock firmware or installation of Ian's firmware to work.

Check out the guide at:  http://ubitx.net/how-to-load-up-a-sketch-on-your-raduino/  and feed back with any issues, as I want to get this right!
