WXR3031 rework station will replace you three devices

obr1740_1

Soldering, deslodering, hot-air works but also a record of your work in a PC – this is the Weller WXR 3031.

Good soldering station is usually a fundament of a workplace. Desoldering station is usually a necessity if you work in development or service. And a hot-air station? – this one is becoming a must at any development or rework of PCBs with SMT components. If we already know, that it´s ideal to have all these three device on a workbench, couldn´t they be integrated into one device?

The answer can be Weller WXR 3031

Right at the beginning it can be said, that in this case a connection into one station brings real benefits, rather than well-known negatives of various „3in1“, „7in1“ and similar products and agents :-).

Perhaps the biggest benefit is saving of space on a workbench and the same control interface for all tools. If you´re familiar with Weller WX2 stations, which we introduced to you in our articles, then you know, that they belong to a very top segment. If we “add” to them a section for a hot air, as well as other additional features and a possibility to connect a vacuum pickup, we receive a top class device which makes every electrician happy.

Briefly:
  • 3 channels
  • 420 (600W) total power
  • temperature 100-450 (550) °C/ 200-850°C (hot-air part)

Available are 4 soldering tools (from micro up to powerful 200W) and 3 tools for desoldering. Concretely WXR 3031 set contains:

  • WXR3 unit
  • hot-air tool WXHAP
  • desoldering tool WXDP 120
  • soldering tool WXP 120

A big benefit for professional workplaces is also a possibility to record your work (traceability – temperature profile) over the USB port to a PC. USB port also serves for a possible firmware update. WXR3031 features intelligent identification of a connected tool and a parameter memory built-in in a given tool, intelligent power save function and a possibility to control several additional devices via the WX port.

WX series meets all requirements for demanding and precise everyday work. High power, user comfort and a wide range of soldering tools and tips will be probably beneficial even for your workplace.

Possibilities of the WXR3031 are very wide and perhaps best illustrated in the attached video. Detailed information will provide you the WXR3031 datasheet , user manual WXR3031 and the “WXR3 Quick start”.
WXR 3031 station was incorporated into our standard stock offer.

Making A SMD Reflow Oven

by packetbob @ instructables.com:

I decided to put together a toaster oven and wanted something that could handle large boards and possibly do small production runs. Doing a web search, you will find many options for toaster oven reflow controllers. They range from one-off designs to DIY boards to full kits. A large number of them are Arduino based. Some controllers just allow the oven to plug in (so you don’t need to take the oven apart) while others integrate completely inside the oven (more work but a much better product in the end).

DIY soldering station

solderingstation-600x224

MatthiasW over at DebuggingLab posted his DIY Weller station clone project, that is available at Github:

At the fpv-community.de Forum I read about a DIY Weller station. Basically an Arduino shield to drive a Weller soldering tip. As there is not much to it, the board simply contains an precision OpAmp, a power MOSFET, 2 buttons for adjusting the temperature and a display to show the current values. This design looks like a good starting point for my own advanced project. As I have lately discovered a 1,8 inch SPI TFT at banggood.com for an amazing price ( ~ 4.60 $ / 3,70 €), I started using them regularly in my projects. So I surely wanted to use it with this soldering station as well.

Universal soldering controller

universal_soldering_controller1

sparkybg shared his universal soldering controller:

The intention was to build the most universal soldering controller I can think of. It can drive any low voltage (upto 24V) iron with thermocouple or resistive sensor, in series with the heater, or separate.
Here is a short list of features:
– power: 9-28V, AC or DC
– 2 separate heater control channels
– 2 independent sensor inputs
– current source on any sensor input 3uA – 12mA, wuth 2 bands (x1, x16) and 256 steps per band
– flexible differential amplifier input selection
– amplifier gain from 0 to 750 in 256 steps
– negative offset selection in 1024 steps
– resistive instrument identification (upto 625 different instruments can be identified by 2 resistors on the connector)
– polynomial floating point voltage/resistance to temperature calculation
– wave shaping to filter out the inductive peaks from series sensor signal
– PID control with power limit
– isolated USB port for firmware updates and live data
– 128×64 OLED display with rich user interface.

Soldering Robot – Head Assembly

Brian Dorey writes about his soldering robot project:

We have finished the soldering iron element slider system and stepper mount for the new soldering robot project.
The soldering iron element slides on a pair or 6mm rails, drylin® accessories, precision aluminium shaft 100mm length (part no: AWMP-06) with drylin® R – Bearings (part no: RJZM-01-06) from www.igus.co.uk which are mounted into milled 6mm aluminium plates. These are bolted to a 4mm aluminium base which has slots milled to allow it to be mounted onto a horizontal frame above the board to be soldered.

The SMD beak

2015-02-03 17.49.33

Vassilis over vpapanik.blogspot.gr has build a nice and simple tool to help him soldering tiny SMD parts on a PCB. The tool consists of three metal parts you can easily find on your parts box and it can be proven to be really helpful as it keeps the SMD parts steady while you solder them. The build is easy, all you have to do is to bend the main rod, file the tip to conical shape and drill the other two rods. All steps can be done in under 30 minutes without special tools. Sure it can be your third hand while assembling your PCBs. He writes:

I ordered this awesome N|Watch kit the other day, which requires some serious SMD hand-soldering skills. There’s always the easy alternative to use a reflow oven, but guess what, there is no stencil included (and no, I don’t have a paste dispenser). In a desperate need of a third hand (!) in order do a neat job, I saw some similar DIY solutions (thumbs up for Google images) and managed to build my own version in less than 30 minutes, just using junk metal parts : the SMD beak !

Reflow Soldering Controller

by pleasantsoftware.com:

This is reflow soldering controller for use with a toaster oven as reflow soldering oven.

I bought the toaster oven in a local super market for about 40 €. There was also a cheaper oven on sale, but I wasn’t sure if it did 250°C, so I bought the more expensive and prettier one.

Since I don’t want to loose the warranty and also haven’t any interest of the oven’s internals, I designed the reflow controller as an oven-external device which directly switches the oven’s mains on/off.

The relay I use is for 6V, but it seems to work just fine with the 5V supply from the ATtiny. On the mains side, the relay is rated for 230V/16A.

The whole controller is based on a ATtiny 45 µController. I use one pin as input for the 100k thermistor for temperature measurement (connected to JP3), one pin controls the mains relay (via a BC140 transistor), one pin controls a LED for feedback and one pin is connected to a switch for user input.

Kristall 511 solder wire won´t dirt your PCB

obr1643_uvod

Innovative flux and a high qualty alloy provide to Stannol Kristall 511 solder wire excellent processing properties with a minimum of clean transprarent residues.

You, who are at production of electronic devices, know, how important is a choice of a suitable solder. A designer of a given device might not focus on a solder used at soldering of the first protoype, bu tin a production it will manifest itself – sooner or later. Not that some solder would be miraculous and otherone unusable, but each one is suitable for something else.

Similarly lie in other segments, even here are some exceptions, when by using the newest materials and know-how from development of solders exist types suitable for multiple applications. One of them is solder Kristall511 Ecoloy with an innovative flux based on synthetic resins. The result is a small spatter and clean, transparent residues, which don´t influence electrical properties of a PCB, i.e. they belong to a “No clean” category – they can stay on a PCB withot cleaning. Kristall 511 is a considerably active solder and it shows its strength even at surfaces with not that optimal solderability and also there, where it´s necessary to solder quickly (for example components that are exceptionally sensitive to temperature). KRISTALL 511 was developed for automated soldering of SMT components, as well as for hand soldering and rework.

This way Stannol, as a producer with rich experience in development of solders (from 1920), produced a combinatio of an alloy+flux with properties meeting majority of requirements of production:

  • small amount of transparent residues
  • excellent spreading even at poorly solderable sorfaces (copper, brass, nickel,…)
  • highly active
  • electrically safe residues
  • low spitting
  • mild odour and small amount of fumes

On stock we have two novelties KRISTALL 511 Sn95,5Ag3,8Cu0,7 (593132) (diameter 1mm, 500g) and KRISTALL 511 Sn96,5Ag3,0Cu0,5 (810050) (diameter 1mm, 500g) solder wires. Technical details can be found in the Kristall_511 datasheet.
