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.

Find the right solder for you

From a wide offer of solders from company Stannol, it´s easy to choose the most suitable type meeting your demands.

The solder matters, it is an undisputable fact confirmed daily in a development and production of electronics. Hand soldering of prototypes, automated machine soldering, soldering of small SMT components or on the in contrast soldering of big joints of massive connectors, rework, … all that wants a solder optimized for a given usage.
As we know, features of a solder wire are determined by an alloy itself (PbSn xx, SnAg xx, …) but in a considerable extent also a flux used. A flux has a big influence mainly on a soldering process, spreading of solder (often even on partially oxidized surfaces), spitting at hand soldering, etc. That´s why despite of often similar specification (according to datasheets), it is still possible to see considerable differences among solders after all. Besides the most important parameters like composition of alloy and flux properties, some features (like spitting and solder spreading) can be really evaluated only at working with a given type.

Over 130-years experience of German company Stannol give a guarantee, that in their portfolio can be found a type suitable even for your work. In a Stannol catalogue can be found favourite “universal” types suitable for the most types of works in electronics and electrotechnics (for example HS10, HF32, Kristall 400) but also specialized types suitable even for soldering of poorly solderable surfaces.

The principle of Stannol products marking is in it, that they are marked by a flux type (HS10, HF32,…) and by an alloy used (Snxx, SnPb,…). A solder wire is available in many combinations flux / alloy , that´s why it is suitable look at their properties in detail and then to choose a suitable type. On stock we keep the most favorite types with fluxes HS10, HF32 or 2630, suitable for majority of joints.

  • HS10 – no-clean flux containing halides, based on a natural resin (colophony). Outstanding properties regarding spreading and electrically safe residues. The flux is non-corrosive on non-ferrous materials. The most popular type for electronic industry.
  • HF32 no-clean halide-free flux with an activated resin (colophony). Outstanding combination of high activity, good wetting properties and small amount of residues. Residues are transparent, hard, dry and non-corrosive. Very suitable even for SMT components, high reliability of joints. Special version HF32 SMD features even lower flux content and leaves minimum residues, that´s why it´s very suitable even for rework, manual adding of components to PCB and similar.
  • 2630 – the most active no-clean flux containing halides. Usable even on places where HS10 is not sufficient. Ideal for surfaces with poor solderability as well as for soldering of bigger joints (thicker copper wires etc.).

Upon request, we´re able to provide you with another types from Stannol production, for example Kristall 400 – no-clean halide-free flux with synthetic resins, with transparent residues and good activity, able to provide excellent soldering results. In general, fluxes, which contain halides are more active and at soldering they feature better wetting. On the other side halide-free fluxes are more safe in respect of possible corrosion around a solder joint and modern fluxes already have very good wetting properties. Normally, neither halide fluxes marked as “no-clean” don´t cause corrosion around a solder joint but at certain circumstances (for example devices intended for very humid conditions) it may be necessary to wash soldered joints from flux residues.

Detailed information will provide you the attached table as well as Stannol catalogue, overview of Stannol soldering materials, overview of Stannol solder wires and overview of soldering fluxes standards.

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.

DIY solder paste dispenser

SP2-600x362

Geir Andersen over at LetsMakeRobots has designed and built this cool solder paste dispenser:

As I’m doing SMD prototypes I wanted to do reflow soldering instead of hand soldering and needed a solder paste dispenser.
The professional ones are not that expensive but you need an air compressor and I was trying to avoid that extra cost and noise. So I came up with this design.
It uses a PICAXE M14 microcontroller and ULN2003 Darlington driver to run the 28BYJ-48 stepper motor. As a stepper the 28BYJ-48 sucks with its gear ratio, but for this purpose it is cheap and has lot of torque. For my type of work and one-off prototypes it works great.

Cutting Mylar Solder Stencils from ExpressPCB and EagleCAD Files

2014-06-13-16.44.09-1024x768

by Juan Chong @ juanjchong.com:

In this post I’ll be going over how to cut out solder stencils for both ExpressPCB and EagleCAD designs on a laser cutter. I recently had a need to create some stencils from both of these programs and spent quite a bit of time at the Dallas Makerspace working with their laser cutter to get the settings just right. I’ll be cutting some designs that are mostly 0603/0805 package sizes, so don’t expect ultra-tight pitch stencils from this technique!

Note: By “beginner’s guide”, I mean a guide written by a beginner. (I made it at TechShop SF, during my first weeks!) I have some technique tips to share, but for more in-depth questions, Google is your friend.

Solder paste allows you to populate a board with many tiny components, without straining your eyes and fingers. Using minuscule components saves space, and you can dramatically cut down the space between them when you don’t have to solder every connection by hand.
