Desoldering braid makes an invaluable service at development or rework.

Everyone who´s ever tried to suck off a solder from a solder pad by means of a solder absorbing braid (wick) will probably confirm, that this tool belongs to a “must have” equipment of every professional or amateur workplace. What´s the charm of a desoldering braid? Above all in the fact, that it´s able to absorb almost all the solder from a given place, thus the most of components can be loosened very easily. Hand (pneumatic) pump surely has its place, mainly when working with bigger components, but at comparison with a desoldering braid it´s similar like if we compared a broom with a vacuum cleaner.

A quality desoldering braid is usually able to absorb a solder so thoroughly, that only a microscopic layer of a solder will remain on a PCB – as if a board was new, unused. It is very advantageous even at a hand rework of SMT components, because it´s desirable the component to lay directly on a board – not askew in a thick solder layer causing a mechanical tension and able to cause even a malfunction of a component (often at SMT capacitors).

To reach a good functionality of a desoldering wick it should be made of a fine gauge copper wires (without oil residues end similar) and it must be treated with a high quality flux. The cheapest braids usually contain only a rosin-based flux, the better ones have a synthetic flux based, which produce less fumes.

A novelty in our portfolio is the novelty from company CRC Industries – braid SOLDABSORB. We keep Soldabsorb in a width of 1.5 and 2.5mm, packed in a blister in 2 pcs (the price is for 2 pcs). Soldabsorb represents a top-level in this segment and is made of a highly pure copper, fine gauge wires and contains a synthetic NO-CLEAN flux. It means, that the flux residues are non-conductive and non-corrosive and they can be left on a PCB. Very fine wires contribute to a high wicking (absorbing) ability.

The usage of the wick is very simple and is based in 4 steps:

  • Place the Soldabsorb wick on the solder joint
  • place the tip of the solder iron on the wick and hold shortly
  • absorbed solder will change a color of a braid, showing that the process was successful
  • when a joint contains a big amount of solder, it may be necessary to cut off a used end of a braid (2-5mm) and repeat the process

In praxis it approves well to adjust temperature of a soldering iron to a slightly higher, than we´d normally need for a given pad and eventually also to use a thicker soldering tip. In especially difficult cases (vias at ground planes of a PCB) it helps to put a small amount of a new solder on a soldering tip, which will decrease an absorbing ability of a braid, it will significantly improve a heat transfer from a tip through a braid to a PCB, thus improving and speeding up an absorption. Before another use of a braid, it´s sufficient to cut off only a very end of a braid (a few mm) fully sucked by a solder.
At the end it´s worth to mention, that after desoldering, it´s good to apply a small amount of solder on a soldering tip to protect it from oxidizing.

Detailed information will provide you the Soldabsorb datasheet.

Power supplying, control, but also signal transmission from various sensors can be confided to ST series connectors.

A word „versatility“ describes well know series Hirschmann ST (STA) perhaps the best. ST connectors are universal because as for parameters, they´re sufficient for majority of applications (16A/250VAC) and they maintain a decent compcáctness. At the same time, they´re available in many versions (M/F, panel/ cable) , so we can create a desired combination – cable/cable, cable/panel.

ST connectors have 2,3,4 or 5 contacts + PE in a compact polyamid (PA) body. Safety and reliability is supported by a metal lock STASIx (bought separately), preventing accidental disconnection and also enabing a fast disconnection in case of necessity.
Connectors for a cable are also available Kwith an extra cable support against pulling off from a cable gland („strain relief“). ST series is so to say a standard for many industrial applications and it finds its place also for example in building automation (intelligent houses, ….).

A novelty in our portfolio is price-gainful set called SETSTAx3 for a cable+cable connection, containing STAS 3N, STAK 3N and a metal lock.

Detailed information will provide you datasheets at particular types below this article. Upon order, even the surface mount types and types with an integrated cable are available.

Top-class component should be equipped with a top class documentation. That´s also a case of many AC/DC and DC/DC modules series from Traco Power.

Demands of various application also vary. While somewhere it´s enough to know, that a given power supply will give us „some DC12V/1A“ or that a given „LED shines green and withstands 20mA“, in majority of cases we naturally need much more about a given component. Somewhere at the end of this chart are applications, where we need to know literally every parameter, including commonly non-mentioned parameters and graphs from a real measurement.

From this point of view, Swiss company Traco Power is really helpful at development and at selecting given AC/DC or DC/DC module, as all power modules are equipped with quality documentation in a form of detailed datasheets, certificates, 3D drawings and similar. Masterpiece – the application notes are available for several „high performance“ modules like for example TEN8WI module.

TEN8xxxxWI is the 8W DC/DC isolating module with a high energy density, enhanced range of operating temperatures and a wide input voltage range( 4:1). Besides a common documentation, there´s also available the TEN8WI application note, where we can find all important information for successful usage even in critical applications (EN50155-railways), including EMC characteristics, thermal consideration, recommended PCB layout and other.

For applications, where we don´t require that wide input voltage range, the standard TEN8 version (non- „WI“) is intended. In the TEN8 and TEN8WI families can be found a large amount of types with various input voltages (input 9-18VDC, 18-36, 36-75 or 9-36, 18-75 at the WI series) and 3.3 to 15Vdc output, including symmetrical ones (for example +-12V). On stock we keep a few versions, all other versions we´re able to supply you in a short leadtime.

Detailed information will provide you datasheets at particular types, as well as above-mentioned TEN8WI application note, TEN8WI certificate, TEN8WI-3D drawing and the TEN8 series filter design.

No need to consider temperature resistance of Multimec 3 and Unimec switches anymore.

Company MEC, Dutch producer of top-class push-button switches Multimec, Unimec and others comes with good news for developers and producers of electronics.

Well-known reliable push-buttons were in majority of cases available in so called standard version (L6, -40…+115°C) and in a high-temperature version (H9, -40…+160°C). From now on, all types will be gradually available only in a „high temperature“ version, which can be identified by „H9“marking in suffix. This applies to Multimec 3 and Unimec series (series Multimec 5 is already from the beginning only available in a high-temperature version).

The main „good news“ is, that these high-temperature types will be available for practically identical prices like standard types. That´s why, even in applications where you wouldn´t necessarily need that high thermal resistance, you can use this high-temp version and profit from unchanged price and potentially wider possibilities of usage of your product.

The most suitable type for you application can be easily found in the MEC catalogue (11MB).

Pleasant actuation characteristics and reliable features of a push button switch Marquardt series 1840 make it attractive for all applications where you require control by a push.

Classic push-button switches are favorite for many decades, maybe also because they´re well known already from the beginnings of electronics. Probably, a nostalgia is not the only reason making them popular, but mainly an easy control, when even an unacquainted person knows, that it´s something “what has to be pushed” to change a status of an electric device.

Exactly a term “to change a status” is important, because at these switches it´s not possible (or not easily visible), whether it´s switched on or off. Though it´s true, that the majority of such switches is a little bit pushed down (lowered) in a switched on status, but the difference is often small. That´s why these switches are not suitable for applications, where from safety reasons it´s necessary to know tha status of the switch before connecting to a mains line.

Marquardt 1840 series switches are available as single-pole switches – 1841 (momentary, SPST), two-pole switches – 1842 and single-pole changeover switches – 1843 (SPDT). Directly from our stock we offer you momentary switches ) 1841.1201 (SPNO) and 1841.1301 (SPNC).
Series 1840 (SPNC) belongs to a top in this segment and offers a really pleasant control and a quality switching system with a mechanical endurance of min. 100 000 cycles. 6A/ 250V is far sufficient for many applications and assembly is simple – by means of an M12 nut supplied. An interesting supplement is also a neoprene cap integrated with an M12 nut, enabling to gain a considerable resistance to water and dust. Also available are 2-pole versions – 1842 and also versions functioning as a push-button (momentary).

There are 2 nuts supplied. One is “regular” – hexagonal and the other one is a round type intended to be used as a top cover on a front panel. Further detailed information will provide you the Marquardt 1840 datasheet.

Switching of three-phase motors or a realization of a sophisticated installation is a breeze with industrial relays Finder.

As we know, a relay is a very versatile component, able to realize also various “sequential” circuits, when for example by switching one relay we´ll switch on a target device and at the same time we´ll enable (or disable) switching of another relay. In these case, it´s an often demand for a relay to have a sufficient number of poles. Majority of such “logic” circuits can be realized even with a common 1-2 pole relays, but it´s not always economical and it also brings another costs for solution of supplying and protection of logic circuits.

Industrial relays Finder series „55“ and „60“ are suitable for a construction of such more complex circuits or for switching of three phase devices.

  • Finder 55 – miniature industrial relay for a PCB or for socket, 2-4 poles, 7-10A (switching current up to 20A), 250/400VAC,
  • Finder 60 – a more robust industrial relay for a socket, 2-3 poles, 10A (switching current up to 20A), 250/400VAC,

Industrial memory cards Apacer comprise hide in themselves much more than usual cards.

If we label a component as “industrial”, we automatically expect that it brings something extra, that it has high reliability, is able to work in a wider range of operating temperatures or by one word, it simply “withstands more”. We can confirm, that this also applies to memory cards and to SSD solutions in general. We often solve situation, when a customer asks us to recommend a suitable memory card because common cards are “going away” after a short time. Real praxis shows, that industrial cards – even though noticeably more expensive than usual cards, are a cheaper alternative in result. Significantly higher reliability and consequently spared money for servicing (data loss, break-off, journey to a customer, …) say clearly in favor of industrial SSD Flash solutions.

Apacer components belong to a top in this segment and they provide a whole set of features and improvements optimizing their performance and contributing to a reliable operation. For example:

  • usage of MLC or extremely reliable SLC chip
  • enhanced range of operating temperatures -40 to +85°C
  • ECC algorithms (Error Checking and Correction), protects data integrity
  • optimal usage of blocks (Wear-Leveling, Flash management) S.M.A.R.T. (Self-Monitoring, Analysis, and Reporting Technology).
  • optional write protection
  • automatic standby and sleep mode
  • bad blocks management
  • Power Loss Detection, Power Failure Recovery
  • possibility to mark protected zones (Secured Protection Zone)
  • safe erase (Core Eraser – quick/ full/ military)
  • total erase of a card (Core destroyer)
  • multiple protection from data theft (Core protector)
  • resistant to water, dust and oxidation (IP57)

Help at selecting a suitable ApacerSSD memory solution will provide you documents eFlash Brochure and eFlash Ordering Guide.
