Bzzzzzz zap I can feel some static!

static electricity
  1. a stationary electric charge, typically produced by friction, that causes sparks or crackling or the attraction of dust or hair.
(Scientists believe that it is not the rubbing or friction that causes electrons to move. It is simply the contact between two different materials. Rubbing just increases the contact area between them.) Static electricity is the imbalance of. positive and negative charges.

Walking across a rug can produce a static electricity voltage of up to 12,000 volts, but static voltage is not life threatening. So it is possible to damage a hard drive with static electricity that is not even felt by the person because it is at such a low voltage. Also, computers become increasingly susceptible to static electricity damage as more and more circuitry is built into them.
The main components affected by these devious charges are semiconductors. This is because they incorporate various delicate components, and when a negative charge is discharged onto it by virtue of static, it causes failures, as there is no conductor that can dissipate, hence causing damage.
Semiconductors, include diodes, microchips, transistors, etc.
Static electricity, causes damage to sensitive electronic components, so if one brings it near electronics, there will be failure.

So how can we address this?

ESD Protection

The electronic industry has placed a growing emphasis on reliability and quality assurance. ESD damage toElectrostatic Discharge Sensitive Devices (ESDS)  can be minimized by using ESD control measures.

  • Handle electrostatic discharge sensitive devices (ESDS) only in an ESD protected area (EPA)
  • Avoid electrostatic potential differences and electrostatic discharges
  • Use wrist straps, approved footwear and floor combination for personnel grounding
  • Wear properly fastened dissipative garments
  • Avoid electrostatic generating materials (normal PE, PVC, PS, etc.) inside an EPA
  • Do not expose ESDS to electrostatic fields > 100V / cm (10 kV/m) !
  • Use only approved ESD protective packaging materials
  • Awareness, personnel training, continuous monitoring are essential for maintaining a static control program

We can offer the following solutions to you:
  1. A wide range of ESD Products.
  2. ESD Training for your staff
  3. ESD measurements and assessing your ESD requirements on site

CK brings you their new Electronic Service Kit.


A great combination of high quality CK tools in a sylish hard ABS case. To view a complete list of the contents click HERE.  
Also available in the range is an Electicians Toolkit 
Choosing the ideal Tool case can make all of the difference when it comes to securing your equipment and enjoying greater ease of access. When you’re searching for the right storage solution for your tools, it’s necessary to first consider a tool case’s size, style, compartments, material, and how often you plan to use it. Selecting a tool case that’s the wrong size, or made of a poor quality material, is not only a waste of money, but can also lead to equipment damage and unnecessary problems.
The core advantages of using a tool case are organization and accessibility. Whether you’re working on a project in your garage, or traveling to different jobs throughout the day, a tool case will keep your equipment safe and well-organized. Rather than having to sort through disorganized tools and choosing the correct ones for each job, you can use one or more tool cases to store specific tools so they’re easily accessible. Some tool cases also have compartments for greater organization and more spacious storage.
When choosing a tool case, it’s important to know which size would adequately house your tools and equipment. Smaller tool cases are perfect for storing tools used for mundane exterior and interior property repairs, and are naturally not always the best solution for professionals who need to carry various types of equipment with them. Larger tool cases are must haves for specialists that require plenty of space and/or separate compartments they can store different tools in while traveling to and from each job.
Another aspect to consider before purchasing a tool case is the type of material from which it’s made. Regardless of how often you would need to use your portable tool box, it’s important to choose a model that’s durable and suits your preferences. Metal and hard plastic are popular choices; however, each type of material has its benefits and drawbacks. For instance, metal is sturdy and able to hold up better in extreme environments especially with a durable powder coat paint finish.

Sometimes we need to make things bigger.

Illuminated Mag lamps
Eyestrain means different things to different people. It can be experienced as burning, tightness, sharp pains, dull pains, watering, blurring, double vision, headaches, and other sensations, depending on the person. If you have any eye discomfort caused by viewing something, you can call it eyestrain.
A range of illuminated ,magnifiers are available, which can be used in an illuminated or non light fashion.  The 8606 model is easily adjusted to get your light and viewing into the right position.  90 bright white Leds lighten up even the darkest project.  Our FZ1090 has some handy attachments adding a helping hand, and even a soldering iron holder.
We have 3 models as shown below. 
SMD LED Mag LampHelping HandsDesktop smaller lamp 

Uses ultra bright SMD LED globes to light the object, and the magnification provides adequate enlargement, and allows ample space to work, solder etc under the lit magnification.

1. Integration of magnifying and lighting. Different magnifications can be chosen.
2. Bright, stable and reliable light. No flashing and not harmful to people's eyesight.
3. White optical lens are available to relax the strain of eyesight after a long time of use.
4. Applications: For an electronic engineer to view and check micro or mini components densely-fitted circuit board or for medical personnel or beautician when lighting or magnifying is wanted.

Are you tough enough for the new tougher CK Dextro Screwdriver range?

CK Dextro strong
Are You Tough Enough For These Profits?

Set to electrify the industry, Carl Kammerling International has enhanced its already popular C.K tools dextro screwdriver range, reinforcing its durability to make it twice as strong as the average human! 
Now up to an impressive 30 per cent tougher, the C.K dextro screwdrivers provide a true test of strength. This toolbox staple has always exceeded the tip strength requirements of ISO international standards. However, through an extensive design optimisation programme undertaken by Carl Kammerling’s dedicated team of engineers and metallurgists, the C.K dextro and dextroVDE screwdrivers are now tougher than ever before, providing screwdrivers with a real difference.
International screwdriver standards for a PZ2 screwdriver require a minimum torque load of 10.3nm. A human torque test reveals a capability of applying approximately 8.2nm of torque, and in independent testing the improved C.K dextro was found to be capable of withstanding over 20nm of torque, making it the toughest yet.
As suggested by its name, the dextro VDE has been crafted purposely for the dexterity required in the nature of the work undertaken with a long, fine neck for ultimate fingertip control. It has an ergonomically shaped dual component handle, injection moulded directly to the blade giving the ultimate bond for increased reliability and durability, and ridges along the head to give extra power in the last quarter turn.
For easy identification the entire dextro range has the tip type marked on the end of each handle, and anti-roll flats, which come in very useful when the screwdriver is put down on a sloped surface.
A premium quality, chrome vanadium steel blade provides exceptional strength and durability, whilst a precision machined tip ensures an exact screw fit and damage free screwdriving. And not forgetting that improved tip, which is now up to 30 per cent tougher!
Watch the video 
With voltages as low as fifty Volts potentially proving extremely dangerous, if not lethal, the VDE approval of the dextro VDE range offers electricians maximum safety. VDE-approved tools are designed to reduce the risk of injury and damage to electrical circuitry. For many years tools have been labelled ‘insulated’, meaning only that they are coated with a material that is not a conductor of electricity. There are even tools on the market that claim they are tested to 1,000V. However, only tools marked ‘VDE’ have passed the rigorous tests set by the VDE Testing and Certification Institute, including being specifically tested to 10,000V of electricity and only these tools offer the peace of mind an electrician needs.
