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.

Even a simple, well-designed tool can help significantly – we´ll introduce to you some of them …

Sometimes, only a little bit is necessary to make our work more happy – a good ergonomic chair, workbench in a suitable height, good lighting … and last but not least also a good screwdriver, magnifying lens, tweezers, or „something“ what can help at extraction of a component from a PCB or at cleaning of a suspicious place with a possible shortcut.

If we´d start by the smallest one, then it could be the ZD-151 set – i.e. six various “surgery” tools serving for bending of THT components leads, extraction of components from a PCB, cleaning of a joint (brass brush) as well as interruption of unwanted connection on a PCB. Especially suitable for work with SMT components is the set of four stainless steel tweezers 816748. By the way, for a work with sensitive components it´s certainly worth to use antistatic wrist band (suitably earthed).

If you already find a place, which should be resoldered or a component should be extracted, then there will be certainly useful desoldering pumps ZD-192 or ZD-108 from an ESD plastic. For a thorough removing of all solder residues, especially at exchange of SMT components, it´s usually necessary to use a desoldering braid, for example Toolcraft – in various thicknesses (1.0-3.0mm) or a top-quality braid with a synthetic flux Soldabsorb.

Soldering tool – that should be laid off into a reliable holder – for example ZD-10 but we´re also able to supply you various original parts from Weller, Ersa and other.

At soldering and especially at a lead-free process, it often happens, that even a relatively new soldering tip gets covered by a thin oxide layer and the tip then “doesn´t catch” solder (poor wetting). If a mild cleaning on a soft-wetted sponge (ZD-937), doesn´t help, or often better – on a dry brass or stainless steel wool – AT-A900, then it might be good to use something more efficient – regenerator of tips Stannol Tippy or Weller TIP ACTIVATOR (T0051303199).

It´s known, that solder smoke and fumes are harmful and your health is surely worth much more than the ZD-153 fumes extractor.

… and will prevent to spread there, where you don´t want to. Fluxes in pen Stannol series Mini Fluxer belong to the invaluable helpers of every electro-technician.

How could I work without a flux so far? That´s a probable question of probably everyone, who once tried action of a solder flux. In a common wire solder, there´s some amount of a flux, usually sufficient for one-time soldering of a given joint, if the components to be soldered are clean and oxides-free. However, we know well a case, when we use for example an older PCB, or an older component with slightly oxidized leads and suddenly it´s much harder to reach an acceptable joint. Similar situation happens at an exchange of a component or any service action, when a solder tends to oxidize on a surface and create various bad-looking creatures, which are quite far from a professional joint. Fortunately, there´s a flux here …

In general, fluxes act in a manner, that a solder is as if „more movable“ after application. It is mainly thanks to the protection against oxidation, change of surface tension and other influences. As a result it means, that a solder spreads well on metals and joints with a given material (what we naturally want) and on the non-metal substances (PCB) is a solder repelled as if on an oily surface.

At an automated „all-surface“ soldering, fluxes are usually applied by wetting (foam) or by spraying. At development and servicing smaller packages are much more practical, for example in a form of a pen. Two novelties in our offer also belong to this category:

  • Stannol MINI-FLUXER X32-10i – halogen free, activated „No clean“ flux, practically residue-free, vey tolerant to various working conditions. Minimum amount of electrically safe transparent residues with a high insulation resistance enables its usage even at visible places and at production of highly reliable devices, including solar panels. Significantly eliminates build-up of bridges, that´s why it´s very suitable even for manual soldering of fine-pitch components.
  • Stannol MINI-FLUXER X33S-07i – highly activated halogen-free „No clean“, resin-free flux, with a corrosion inhibitor, very suitable even for copper surfaces – clean, passivated or lacquered by rosin-based agents. Excellent wetting even on poorly adherent surfaces. Excellent spreading manifests by for example trouble-free filling of vias by a solder.

Stainless steel spring mechanism of a pen enables simple and precise dosage and also a long pen lifetime. During application, it´s only necessary to softly press on the tip. Both fluxes are in our stable stock offer, available immediately or in a short leadtime (in case of a temporary out-of -stock status).

Detailed information will provide you the Stannol-X32-10i and Stannol-X33S-07i datasheets.

Despite a low power consumption this relay handles 5A/250VAC while maintaining a considerably long lifetime.

If we should mark an electronic component by a term “sympathic”, then the FTR-MY MY relay should be one of adepts …. Why? It´s simply chic. FTR-MY is:

  • slim (5mm), so it doesn´t take much time on a PCB (only 100 mm2)
  • relatively low profile (12mm), so it´s usable in majority of applications
  • very sensitive (110 mW), operates even at 54 mW
  • handles 5A/250VAC but thanks to bifurcated gold-plated contacts doesn´t have problems neither with small signals
  • outstands by long mechanical and electrical lifetime

In praxis it looks so, that on a small PCB space, where we´d usually fit 3 common relays, it´s possible to assemble 10 pcs FTR-MY.
Despite small dimensions FTR-MY has an isolation strength of 3000VAC. Even thanks to a low power consumption, max. operating temperature is +90°C and at the same time FTR-MY enables dense assembly without worry about overheating.
The last bonus of FTR-MY is a considerably affordable price. By its specification, this series is comparable (or even better) with series NY.

Detailed information will provide you the Fujitsu FTR-MY datasheet.
The first representative in our stock is type FTR-MYAA005D with a 5VDC coil.

Internet is “good” not only for people but also for various devices (things), what we´re experiencing on every step. And that´s only the beginning ….

Term „Internet of Things – IoT“ is known already for several years and in general it addresses connection of various devices to internet. What´s the benefit of internet connectivity for various devices, sensors and other modules? It´s quite a lot, what IoT enables, for example:

  • remote data read out, practically from any place on Earth
  • remote control
  • diagnostics, watching and early prevention of faults
  • minimizing of physical control and service intervention to a given device
  • real-time evaluation and many other

A common feature of all „IoT“ devices is, that they are uniquely identifiable. A global expansion of internet caused, that technical equipment (for example Ethernet/ serial interfaces) enabling implementation of TCP/IP Ethernet or WiFi into a target device are available for affordable prices, so it´s relatively simple and affordable to add internet connectivity into a target device. Using this connectivity we gain a possibility to use a given device in virtually any environment and any country.
Already a small, easily usable module like for example Xport is, is able to provide a TCP/IP connectivity and provides a possibility to administrate a given device through a web server.

Internet of Things should be beneficial for both – producer and also for user (or administrator) of a given device. A user is prospering from an easy data collection through a practically everywhere-available network and a producer is in many cases able to diagnose or service given device within few seconds or minutes.
One of the biggest advantages of using internet as an “interconnecting element” is a possibility of unlimited expansion of connected devices and relatively simple data processing. Many smaller but also renowned companies already today offer a software development – customized for a given IoT application.
A characteristic feature of IoT is, that generated data originate from “things”, not from human as it is so far at the majority of nowadays internet content. Direct data transfer without human intervention increases accuracy, eliminates possible mistakes and mainly – saves human work and attention.

One of many ways how to IoT enable your device is to use some of common embedded microcomputers. UDOO, Embedded Artists, BeagleBoard, Raspberry Pi, Banana Pi and many other modules provide for an affordable price a considerable computing power, wide connectivity and intelligence to a target device. Finally, a display with a touch panel in connection with such a microcomputer usually creates a user friendly (HMI) interfaces. As a result, such a device is in majority of cases much more attractive for an end user. A brief comparison of some popular embedded microcomputers can be found here.
The newest term on this field is the „Internet of Everything“, i.e. internet connecting people, processes, data and things. Perhaps only the nearest future will show a real status, which can be influenced even by you – by a design of your devices.

Minimal power consumption, slim design and a big amount of available versions with multi-color backlight – these are some benefits of the EADOG series displays.

EADOG series is familiar to many of you and probably it´s your favorite one from these main reasons:

  • displays are unusually flat (thin)
  • the have a very low power consumption of 100-s uA (without backlight)
  • wide possibilities of backlight, monochrome and also RGB
  • some types are well legible even without backlight
  • simple communication through 4/8 bit or SPI interface and newly even I2C

So far, types with up to 128x64px or 3×16 characters were available. The most recent additions to the EADOG family are bigger types with resolution of 160x104px (EADOGXL160), 240x64px (EADOGM240), 240x128px (EADOGXL240) and 4×20 characters (EADOGM204) and appropriate backlight modules EALED66x40, EALED94x40 and EALED94x67. Also these new types maintain a low profile – only 5.8 or 6.5mm with backlighting. A positivity is that even these new types are based on standard LCD controllers.

A guide at a choice of a suitable combination of display +backlight will provide you the application described in our article – Start with the EA DOG displays for free.

Detailed information will provide you the datasheets at particular types.

New graphic chips supporting capacitive touch screens – FT801 with the “EVE” technology from company FTDI bring a simple usage even for these perspective displays.

FT801 brings together advantages of the „Embedded Video Engine“ (EVE) concept and advantages of capacitive displays like easy control, interactivity and usually a higher brightness and overall vividness of these displays.

New chip FT801 is functionally practically the same as the initial EVE chip – FT800. It supports display, audio and touch interface with a capacitive touch screen via an I²C interface connected to a standard touch controller.FT801 has multi-touch capabilities enabling 5 independent touch points to be simultaneously determined (so called Extended mode). This facilitates the deployment of human machine interfaces (HMIs) usable by several people at once, or where a variety of complex hand gestures can be detected. The IC’s sophisticated hardware engine has the ability to recognize touch tags and track touch movement – delivering notification of up to 255 touch tags.

The capacitive touch panel module (CTPM) asserts an interrupt when a touch is detected, signalling the FT801 to read the touch data via I2C. Additionally the FT801  supports a Compatibility touch mode, where existing FT800 application code can be run with single touch events detected.

The device is packaged in the same 48 pin QFN footprint as the FT800 and enables to use practically the same display design as at FT800, including 3 in1 functionality (Display, Audio and Touch) and 1/16th pixel resolution. A 12MHz crystal oscillator with PLL can deliver a 48MHz or 36MHz system clock.

Detailed description can be found in the FT801 datasheet.
