How to Choose a Continuous Monitor for Your ESD Control Program – Guest Blog

by Craig Zander, Transforming Technologies

In Craig’s latest Guest Blog for Q Source, he provides tips for how to choose a continuous monitor for your ESD control program

The first step in a quality ESD control program is grounding your personnel. People walking in a facility and performing common tasks generate a static charge. If not grounded, the voltage accumulated through this charging may be transferred to your product and can cause significant or catastrophic damage to electronic devices.

The most common method for grounding people handling electronics is by using a wrist strap and coil cord. The wrist strap and cord transfer any voltage from the person to ground. When a wrist strap system is functioning correctly and worn properly, it is extremely difficult to accumulate more than a few volts on a person, which, in all but the most extreme cases, is not enough to cause damage to devices.

Wrist strap systems should be tested on a regular basis.

If the wrist strap system is malfunctioning or worn improperly, the voltage may continue to grow and accumulate to levels that can damage most electronic devices. Therefore, it is very important that the wrist strap system be tested on a regular basis to assure that it is functioning properly.

There are a number of ways that the wrist strap system can be tested, and the best method depends on the number of employees in the facility, the critical nature of the product (i.e., medical, aerospace, military, high value), and budget.

One of the most common methods for verifying wrist strap performance is the wrist strap/footwear test station. The test station(s) is placed near the entrance to the ESD Protected Area (EPA) and employees test their wrist strap to verify its operation before they are allowed to enter the EPA. The testers have a wide range of capability and costs. Some testers have a simple pass/fail indicator while other testers have digital readouts and data logging capabilities to record the test results for each employee. While these testers meet the requirements of regular testing of the wrist strap, there are a number of potential drawbacks:

• Test Frequency: How often the person goes to the test station varies between companies. Some companies require testing at the beginning of each shift while others test every time the person leaves the work station for breaks. In each case, should the test indicate a failure of the wrist strap, there leaves a question as to when the failure occurred and how much product was handled with the failed strap. For high reliability and value products the customers of this company may want to know the disposition of the product that was handled during the time between tests.


• False Security: When testing a wrist strap at a test station, only the wrist strap, cord, and person are tested at that precise moment. The situation could change once the operator reaches the work station. The operator could adjust the strap after testing, the resistance could increase due to dry skin conditions, or the ground jack at the work station could malfunction. All of these scenarios could lead to high voltage accumulation on the operator that would not be detected by the tester.


• Wasted Time: Depending on the size of the company, there can be a line at the test station of employees waiting to test their wrist straps, effectively delaying the time they spend on productive activities.


• Record Keeping: Most companies require their people to sign-in at the tester and record the results. There are some systems that automatically record and store the results after the employee has swiped their ID badge. Someone in the company still must maintain and review the test records to assure that everything is working as designed, which can be tedious and time-consuming.

To address these drawbacks, many companies are now using continuous monitoring to verify that the wrist straps are functioning correctly. Continuous monitors are located at the work station and provide an audible and visual indication when the wrist strap system malfunctions. Once the operator hears the alarm they do not touch the product until the problem is resolved and the system is functioning correctly. With continuous monitoring systems, you avoid waiting in line for testers, eliminate the extensive record keeping, and you remove doubt that the product may have been handled by an ungrounded operator. There are no more decisions to be made on what to do with product that was handled by ungrounded operators, as there is no longer any time between tests.

There are a few options available today for continuous monitoring. Some monitors will simply verify the operator wrist strap, while others will verify the wrist strap, the work surface ground, and possibly other equipment grounds.

Capacitance/Impedance Monitors

Some continuous monitors use capacitance or impedance to verify that the operator is connected to the system. These systems allow the company to use the standard single-wire wrist strap and coil cord system and are typically the lowest cost option for continuous monitoring. These monitors operate by using a capacitance or impedance circuit to estimate the resistance of the operator wearing the wrist strap. Since the system is not making an actual resistance measurement, these systems can sometimes be fooled by high skin resistance of the operator and may provide false passes.

Dual Conductor Resistance Monitors

Dual conductor resistance monitors use a special wrist strap and coil cord to incorporate the operator in a resistance measurement. Instead of the single conductor wire found on standard wrist straps, this monitor uses a dual-wire coil cord and a wrist strap that has two isolated halves. A voltage is sent down one of the wires and into the wrist strap. When the person is wearing the wrist strap properly, their skin completes the circuit and the signal returns down the second wire to the monitor. This system assures that the operator is electrically connected to ground.

Many companies are now using continuous monitors like Transforming Technologies Ranger Series.

While dual conductor resistance monitors provide the most reliability, they also typically have the highest cost and require special wrist straps. A new series of dual-wire resistance monitors (from Transforming Technologies) are priced closer to the single-wire systems, but provide the reliability of dual wire. The CM1601 Resistance Ranger provides dual wire monitoring for a single operator, and the CM1602 Dual-Wire Resistance Ranger monitors the operator and one work surface ground. Transforming Technologies also offers great options for dual-wire wrist straps and cords that provide both excellent quality and value.

The Importance of Testing & Monitoring Your ESD Grounding Devices – Guest Blog

by Craig Zander, Transforming Technologies

In Craig’s debut Guest Blog for Q Source, he explains the importance of testing and monitoring of ESD grounding devices.

Transforming Technologies PDT 800K Test Station

The first line of defense for protecting electronic devices and assemblies from damage due to Electrostatic Discharge (ESD) is to properly ground all personnel that come in contact with the product. When a person is effectively grounded, all of the voltage that accumulates on their body when moving rapidly travels to ground before it can affect the product.

The most common and reliable method for grounding operators is the wrist strap and coil cord combination. The conductive materials inside the wrist band contact the skin and transfer the voltage from the operator through the cord and to ground. When worn correctly, and tested or monitored, wrist straps are the preferred method for grounding people.

When grounding a person through a wrist strap, ANSI/ESD S20.20 requires the resistance of the person to equipment ground to be less than 3.5 x 107 ohm (35 meg ohm). Typically, the resistance to ground of a person properly connected with a wrist strap is just over 1 meg ohm (the value of the resistor in the cord assembly).

Wrist strap and coil cord assemblies need to be tested or monitored regularly. Some companies chose to test the wrist strap system one or more times per day at central testing stations (for example, the PDT 800K Test Station). Other companies opt to continuously monitor (using a device such as the CM1602 Constant Monitor) the wrist strap connection so that product is not handled if the grounding system fails.
 

Transforming Technologies CM1602 Constant Monitor

There are situations, however, when being connected to a ground jack via a cord is not conducive to efficient or even safe operation. Operations that involve frequent transportation of product within the facility, as well as operations that involve machinery, present a challenge to the wrist strap and coil cord grounding method. In these cases, factories may use a combination of conductive flooring and foot grounders to effectively ground the operator.

The requirements for grounding a person through flooring and footwear have changed in the ANSI/ESD S20.20 2014 Standard. Previous versions of ANSI/ESD S20.20 provided you with two options. If the resistance from the person through the footwear, through the floor and to ground was less than 35 megohm, no further testing was necessary. If the resistance was greater than 35 megohm, you could still meet the requirements of the standard if the resistance was less than 1.0 x 109 ohms and you can demonstrate that the operators generate less than 100 volts. The latest version of S20.20 (ANSI/ESD S20.20-2014) requires the resistance test and the walking voltage test for qualifying flooring and footwear materials together. While many flooring and footwear options may pass the resistance test, it has been discovered that some combinations of floor materials and foot grounding materials do not work well together.

To test the walking voltage generation of flooring and footwear systems you use ANSI/ESD STM 97.2 Floor Materials and Footwear - Voltage Measurement in Combination with a Person. This test involves recording the voltage of a person while they perform a repetitive walking pattern. To record the voltage you can use a charge plate monitor with data recording capability, or a similar instrument with the same specifications listed in the test method.

Body voltage measurement test set-up.
The new software “Digilloscope”
can mark the five highest
peaks automatically and calculate
the average value.

Transforming Technologies developed the Warmbier WT5000 Walking Test Kit to meet the needs of the ANSI/ESD STM 97.2 test. The WT5000 is a battery-operated instrument that is easily transported to various areas of the factory floor. The system includes the trademarked data acquisition and analysis software “Digilloscope for Windows™.”

The WT5000 records the voltage on the operator while they are performing the walking steps called out in the standard. Once several repetitions of the pattern are complete, the software will provide the peak voltage and average value. The data is used to confirm compliance to standards and to determine the lowest possible voltage device (Human Body Model Discharge Threshold) that can be handled in the facility.

Thanks for that very important information about ESD control and testing, Craig. We look forward to future Guest Blogs to learn from your expertise.

Flux Cleaning Myths: The Basics - Guest Blog

by Steve Allen, VP Marketing and Innovation, ACL Staticide
 
In Steve’s latest Guest Blog he focuses on a few myths about flux cleaning

There are many myths and misunderstandings about cleaning solder flux from printed circuit boards. Let’s address some of those primary PCB cleaning & preparation myths and concerns for a variety of rework and repair operations.

To begin, we clean and remove most flux residues to prevent metal oxidation and generally poor electronic circuit connections.

Technologists and technicians alike are often advised to clean boards post-soldering processes with isopropyl alcohol (i.e., IPA). But there are proven chemical reasons for not using a hygroscopic solvent like IPA (hygroscopic solvents draw moisture from the air to themselves as an equilibrium mechanism) for basic board cleaning and further process preparation.

In most instances, IPA is too aggressive for most plastics and can intrude into parts and spaces creating undesirable effects. IPA is known to dissolve polystyrene and other types of plastic capacitors. By dissolving various materials, a potential low-ohm and conductive film is spread over the surface of the PCB while the flux itself (typically a very high solids material) is left untouched in a host of board surface areas, and in particular, at the solder joints. Leftover flux materials can be detrimentally conductive in many instances.

A LOOK AT FLUX MATERIALS

Rosin-based flux is generally not conductive unless it is baked on at extremely high temperatures (caramel or black in color). Generally, no-clean flux is just that. It does not always require cleaning and you may leave it on. Many low-solids flux materials, when applied under a correctly controlled process, will completely evaporate with time. Most water-soluble fluxes need to be removed simply because they leave behind a soap-scum-like residue, which is generally conductive.

Additionally, there are some very aggressive fluxes like RA that must be removed as they contain very acidic substances. RMA is the most prevalent rosin flux (RMA rosin = mildly activated and RA rosin = less activated). It is actually not the rosin that performs the flux activity, but another substance in the flux compound, which promotes spreading and adhesion. The basic rosin material is simply a carrying vessel for the active flux ingredient.

FLUX WORKS ON TWO FRONTS

When activated (and temperature controls this; most fluxes kick in around 100° C or 212° F), flux is a very reactive element that wants to bind with oxygen molecules. It is so reactive it can strip oxygen molecules that have already bonded with copper. So, it converts copper oxide back into basic copper. The second thing flux does is lower the surface tension of the solder. This lets the solder flow over the soldered surface, spread, and adhere.

Under a correctly controlled process, the flux is given some time to activate and do its work before solder is applied. Wave solder machines apply warm flux to the board first, then let it soak for a few seconds as the conveyor moves over a warming plate, and finally the flux is fully activated. The board then passes through the solder wave where the flux totally evaporates and essential leaves behind a clean board.

Solder paste works in a similar way. When conducting reflow processes, you have a ramp up to flux activation, a hold phase to let the flux do its work and evaporate, and finally, a ramp up to liquid phase where the solder melts and flows on the remaining flux. In theory, if reflow operations are done correctly, there should be minimal flux residue and board washing is simple or may not be required at all.

Boards that have been reworked (e.g., manually touching one individual component) will have residue and require washing with flux removers. The flux in solder wire is a different composition than the flux found in pens or liquid form. The flux in solder wire is dry powder and is more aggressive than paste as it has a shorter time to do its work.

Plus, there are specially formulated fluxes like the gel fluxes or tacky fluxes. These are formulated for the rework process, and the practice is to use a lot of it; so much of it that there is excessive residue and you need to remove it. The same goes for pen fluxes, which are also for rework. Most fluxes for wave soldering come in a 55-gallon drum, which is not something most end-users keep on the workbench!

In general, when performing handwork, you will need to clean the board unless no-clean is used, when doing reflow or wave soldering. If aesthetics are key, it’s important to clean. And, every kind of flux has its own specific flux remover. Some flux removers are broad spectrum. Most flux removers require flood cleaning; you need to use a substantial amount to effectively clean and wash a board. Simply squirting a tiny bit on does not work. It just leaves goop all over the board like a sticky film. You need to flood it on, let it soak for a few seconds, and in many cases, scrub with a brush. Then repeat the spray process to wash the “spent” material off the board. As a final process, let the board drip out and spray once more. If needed, apply warm air to dry. Never blow air using your mouth (human breath actually contains saliva, which is acidic). As the flux evaporates, it cools down the board which pulls moisture out of the air. Always use your reflow hot air gun for any type of final finishing and drying.
