A brushless motor provides an extremely long operating life and extends the intervals between routine maintenance schedules. Electric screwdrivers with brushless motors have low maintenance requirements and eliminate the need for replacing the common expendable parts associated with non-brushless screwdrivers such as carbon brushes, rotors, switches and other contact points.

The LF-Series is an economical brushless electric torque screwdriver. The durable power tool features a Swiss Maxon brushless motor design. Heat generated by the motor is reduced and screwdriver performance is always at the maximum level. The reliable assembly tool ensures quality, cost savings and a reduction in overall failures. Mountz brushless electric torque screwdrivers are designed for precision torque control and are state-of-the-art in the assembly industry.

In addition to lower maintenance costs, the LF screwdriver is ESD certified, ensuring less than 1 Ohm at the bit tip. Manufacturing engineers involved with microelectronic products are aware of the importance of controlling Electrostatic Discharge (ESD) failures. Lapses in preventing the occurrence of electrostatic discharge can affect production yields, manufacturing costs, product quality, product reliability, reputation and profitability. ESD management with power tools reduces overall ESD failures. Don’t permanently damage an electronic product, be sure to select an ESD compliant tool. Making a safer world through accuracy and precision is the core purpose at Mountz.

The LF screwdriver models are available in “Push-to-Start” or “Lever-Start” configurations with various models covering a torque range capacity of 0.8 to 15.6 inch-pounds. The power tool can be connected with the Scout screw counter. Complex fastening regimes with multiple screws and high-speed production can lead to missed screws and compromised quality. A screw counter helps manufacturers detect and eliminate costly screw-fastening errors during the assembly process.

Using a quality brushless electric screwdriver makes a safer world through accuracy and precision. Controlling torque is essential for companies to ensure their product’s quality, safety and reliability isn’t compromised. The failure of a three-cent fastener that isn’t properly tightened can lead to catastrophic or latent failures. Fasteners that are insufficiently fastened can vibrate loose and excessive torque can strip threaded fasteners.

Why to use DC Brushless electric screwdriver

Why to use DC Brushless Electric Screwdriver:

The most difficult job can be done easily if the right tools are provided. If we just talk about loosening and tightening of screws, it is very important job during assembly of most of the products and surely during final assembly. It is a time consuming process and in many cases, if not done precisely, it can create damages and the field failures. If done manually, it will take a lot of time, marks on the work piece due to excessive handling, variation in torques from piece to piece and will end up with a finished piece with varying quality and thus field performance. In many cases, this is not acceptable.

Thanks to the Electric screwdriver that makes the job easier, which is one of the best tool that reduces the time of assembling any electrical or mechanical devices. Electric screwdrivers provide a great advantage over other options of screw fasting tools. These Electric Screwdrivers are suitable for everyone who deals with electronics assemblies and wherever precise and repeatable torque is required.

Selecting a correct technology and the product may drastically change the yield, operating cost and stable product quality.TYPES OF ELECTRIC SCREWDRIVERS

1) A simplest option is a AC Electric Screwdrivers. These are a good low cost option but comes with few major drawbacks with other technology screwdrivers.

1. These are semiautomatic screwdrivers. This can work on clutch principal and can keep rotating freely after achieving the set torque. This keeps using the power and keep putting the torque on the screw head and some time damages the screw head and if it slips, you can have a mark on your work piece and creates rejections.

2. Power Hand tools which are used continuous for the whole shift/day should not operate on direct 220V supply. This puts the operators at great risk of Electric Shock if something happens with the screwdriver power circuit. So in general AC screwdrivers should be avoided.

3. The leakage voltage on the tip can be very high and can damage the electronics very easily. So AC screwdrivers should surely be avoided for Electronics production.

       D. Output varies with change in input voltage and frequency.

2) DC Electric Screwdrivers:

For assembly of Electronics products, product require precise torque repeatability, DC screwdrivers are the best option. These operate at much lower voltage and are much safer than the AC 220V screwdrivers. DC Screwdrivers can be fully automatic to ensure screw driver stops immediately after achieving the torque.

DC Screw drivers are in general of 2 categories:

1. DC Brush Screwdrivers

2. DC Brushless Screwdrivers.

DC Brushless Screwdrivers are the best options in Electric Screwdriver category. The advantages are:

1. The life of the Brushless motor is much more than DC Brush motor. he DC motors used in these screwdrivers are generally avionics grade and lasts many many years without any maintenance.

2. As brushless motor does not use brushes, the breakdowns are very less than brush screwdrivers. No need to change brushes periodically.

3. Brushless screwdrivers have to be used for Electronics production as they do not generate Conductive Carbon Dust which can damage the electronics circuits.

4. Brushless Screwdrivers has to be used in Clean Room operations as they do not generate carbon dust.

5. Brushless screwdrivers do not generate sparks so do not product EMI disturbances.

6. As brushless has no sparks, these do not produce heats and can be used for long hours. This also results into lesser fatigue to operator.

7. No brush means no friction and thus much quieter operation.

8. DC Brushless screwdrivers are lighter, quieter, long life.

9. All DC brushless screwdrivers are automatic so immediately stops after achieving the torque and this saves the product and the screw head from any damage. Reduces noice pollution, reduces operator fatigue and are thus in long run have the best price performance.

These DC Brushless screwdrivers are plug and play. They come with their AC-DC adopters and can be plugged to AC 220 V supply. You need to select the correct screw bit as per the screw and need to set the required Torque. Check the set torque with torque measuring device and your screw driver is ready to go.

Usages of DC brushless screw drivers are increasing regularly due to their trouble free long life. The pricing has also dropped by some of the brands like Sudong to make them very affordable and thus addressing the only issue of pricing associated with DC brushless screwdrivers.

Almost all the major brands for Fans, TVs, Toys, Mobile Phones, Computers and IT products etc uses DC brushless screwdrivers. Drop in DC brushless screwdriver pricing has changed the preference of the user and have established DC Brushless Screwdrivers as the preferred choice of Electronics assembly floors.

Testers are one of the simplest solutions, used to test current and voltage continuity in any circuit. Indispensible for any electrician, the testers are very simple and interesting devices. This article will explore the internal structure of one such commonly used circuit tester.

The user is required to be on the floor while using the tester so that he can serve as ground when current flows. In order to test the live wire, the user’s body must be in contact with the metal cap on the top of the screwdriver when the tester is put in contact with the wire. This completes a genuine electrical circuit and the bulb will light up once the tester senses voltage.

Fig. 1: Tester Set Up

Fig. 2: 

Screwdriver Cum Tester

The tester shown above is a screwdriver cum testing circuit. The core of the tester is located near the head of the screwdriver. The plastic casing under which the tester circuitry is placed serves as an insulator.  As the metallic rod is the conductor part of the tester, in order to protect the user from getting an accidental electric shock, a thick sheath of plastic insulator is placed over metallic rod

Structure

Fig. 3: 

Metallic Cap at Screwdriver Top to Hold Circuit

A threaded metallic cap is at the top of the screwdriver holding the circuit inside. The cap needs to be grounded when the metallic rod is inserted in the plug. The power socket is analogous to the positive terminal of a battery. Just like in the case of a battery we need to connect the other end of the circuit to the negative terminal where the current sinks in, we need a sink for the current from the power source too. The ground acts as that sink in this case. Most of the time, the user forms the link to ground for the circuit which is created when rod is inserted in the power source.  The user does not get any kind of shock because there is already current limiting resistors in the testers and also because a dry human body has very large electrical resistance

.

Neon Bulb Assembly

The cap is followed by a spring. The spring has a dual functionality of acting as an earth wire and connecting the tester circuitry to the cap when screwdriver is placed inside a socket.

Fig. 4: 

Screwdriver Circiut Set Up

After the plastic insulating sheath is removed, the circuitry of the screwdriver can be seen clearly as shown above.

Fig. 5: 

Neon Bulb–Spring Wire Connection

The above image shows the neon bulb connected to the spring through a wire.  It serves as an indicator of current whenever the metallic rod is plugged inside an active power source. The neon bulb gives output instantaneously and doesn’t get heated due to high voltage. The current requirement of the bulb is quite low and acts quite satisfactorily when circuit is grounded with the help of human body.

Fig. 6: 

Resistor to Connect Neon Bulb with Metallic Rod

A resistor like one shown in the picture above is connected to the neon bulb from one end and to the metallic rod from the other.  The maximum current from the power source that can travel to the neon bulb is limited by the resistor.

Metallic Rod 

Fig. 7: 

Metallic Rod Cum Screwdriver

The metallic rod is placed on the line upon which voltage has to be tested. Additionally, it serves the purpose of a screwdriver for general purpose use. In this way a very simple electrical circuit is used for debugging circuit breaks and tests their continuity.
