  • Why Use Ionizers

    You’ve heard about ionizers before...but do you really need them? If you want to protect your workstation from electrostatic discharge (ESD), then the answer is most likely yes.

    Certain preventative measures can be taken to protect your workstation from electrostatic discharge. In order to maintain a proper ESD control program you will sometimes need to use additional equipment -- this is where the ionizer comes into play.

    Below, we’ll go over four methods for reducing electrostatic discharge both with and without the use of an ionizer to show you the difference.

    Three Ways to Reduce Electrostatic Discharge Without an Ionizer

    In an ESD protected area, insulators can be controlled by doing the following:

    1. Use insulators and maintain a perimeter
    In addition to using a grounded work surface, be sure to use insulated items. These insulated items should be a minimum of 30 centimeters away from all ESD sensitive items at all times.

    2. Use ESD protective items
    To add an extra layer of precaution, replace your insulative items with fully ESD protected versions. For example, instead of using a regular drinking cup at your workstation, replace it with a fully insulated thermos.

    3. Periodically apply topical anti-static agent
    For items which cannot be replaced with an ESD protected version, protect against electrostatic discharge by periodically applying a topical anti-static agent. Examples of such items might be your keyboard.

    Why use an ionizer

    When none of this is possible, the insulator is termed process essential and therefore neutralization using an ionizer should become a necessary part of the ESD control program.

    How ionizers remove electrostatic discharge
    While conductive items can be discharged of their negative ions by being placed on a grounded surface, an insulator will still maintain a positive charge when placed on a grounded surface. Here’s an example:

    This instrument is a digital static field meter which measures voltages associated with electrostatic charge. If we rub two paddles together -- one an insulator and the other a conductor -- and hold them over the field meter the meter shows that the insulated paddle holds many thousands of volts, which in this case is a positive charge.

    The conductive paddle holds a much lower negative charge but it is still charged.

    If we place both paddles on a grounded surface and hold them over the field meter again, the insulator is still holding a large positive charge.

    However the conductor is no longer holding a charge. By placing the conductor on a grounded surface the charge was transferred to the mat and away to the ground.

    An ionizer can help maintain an ESD protected workstation for both insulators and conductors.

    Once the ionizer is turned on it sends out thousands of matching pairs of both positive and negative ions in the air flow. If we hold the positively charged insulative paddle into the air flow it will attract negative ions thereby neutralizing the charge on the surface.

    It’s like magic...or better yet, science!

    Still have questions? Watch our instructional video to learn more about why you should use ionizers here.

    What size ionizer is best?
    The size of the ionizer needed depends on the size of your workstation. For small workstations and desktops not more than 1-4 feet, a single-fan ionizer will work. For larger workstations or a grouping of desktops, several overhead multi-fan ionizers may be more suitable. As a supplement, or to reach small interior areas and remove lodged debris, a point-and-shoot ionizer or ionizer gun works best.

  • Is Water Harmful to Electronic Components?

    hose-spraying-waterMany experts in the electronics assembly world will cringe when they hear about a manufacturer hand-washing their boards with soap and (gasp!) water. The first point to bring up here is that boards should never need to be washed. This is a clear indication that you are somehow bringing dirt into the process, whether through alcohol, brushes, or something else the boards are coming in contact with.

    Know Your Water Grade

    There are three grades of water that you can use to clean the boards; tap water, distilled water, and deionized (DI) water. For this type of precision cleaning you should never use tap or distilled water, which themselves contain contaminants that can affect your boards. If you must clean your boards with water, the only choice is deionized water.

    Deionized water is measured by the water’s resistance to electric current. 50kOHM is standard and can be purchased easily and at a relatively low cost. 1 megaohm is really the minimum required for this type of precision cleaning. In high-precision manufacturing, such as semiconductors, 20 megaohms is the industry standard. Obviously cost and availability are both big factors. As you increase the pureness of your water, it also becomes more difficult to handle.

    One option is a sealed, closed-loop system which purifies the water, performs the cleaning task, and then recycles the water. However, this type of system is costly and can result in a slow through-put. Given these restrictions when using water in the cleaning process, more and more manufacturers are switching to cleaning with solvents. The ideal solvent is strong enough to remove the contamination, while still mild enough to not damage any components on the board.

    GoKimco has a complete line of solvents, ideal for finding this healthy balance for cleaning your boards.

  • Gauging Solder Paste Volume

    stencil-printingKnowing just how much solder paste to dispense onto a stencil for a production run can often seem like a guessing game. The ultimate goal is for the paste to completely fill the aperture and release onto the board with 95% transfer efficiency. If the board is not sitting flush again the stencil, then you may see a greater than 100% transfer efficiency. This can lead to a final paste height that is higher than anticipated. Too little solder paste, and you risk not covering the board entirely, leading to an array of problems.

    The amount of paste that you dispense onto the stencil will vary depending on the size of your production run. For a smaller number of boards, ten or under, a minimal amount of paste will be needed to achieve the smooth, rolling action that you need. For larger production cycles, you will want to apply the maximum amount of solder paste possible without loading the squeegee too high, creating flooding and spilling over the sides. A good rule of thumb is 0.75” diameter down the length of the squeegee as a minimum and a 1.5” diameter as a maximum.

    Operators should always be watching for paste leaking out of the sides of the squeegee, which can result in skip defects. Paste remaining idle during the printing process can dry out and harden faster. To prevent this, operators should be trained to open the printer regularly, every 30 minutes is a good rule of thumb, and reposition the paste to the middle of the squeegee.

    It is good practice to print one dummy board before each production run. This first run often uses an excessive amount of flux and can pick up any dust or contamination that can then be loaded into the apertures of the board. Running this test board also ensures that the paste is rolling and that the squeegee is set up properly, with no streaks left behind.

    Using a quality solder paste paired with the right squeegee can make a big different in your product run.

    GoKimco has a complete line of solder paste and quality squeegees to ensure that your production process runs as smoothly as possible.

  • Epoxy Bonding Problems on RoHS Boards

    epoxy bonding rohsIf you have seen problems with epoxy bonding components to RoHS circuit boards, you are not alone. This may be related to the surface energy of the board. Generally high surface energy is a good thing, while low surface energy is detrimental. The surface energy of the solder resist varies with the many types available. Oven curing the solder resist tends to lower the surface energy because the silicones are then forced to the surface during the curing process.

    It may be useful to perform a simple control test to investigate the surface energy of the boards. This can be done using dyne pens or a contact angle test. If you are using a dyne pen, 36 to 38 dynes is average. A no-clean, assembled board would be about 32 dynes, and you would not want to work with anything lower than this.

    To perform the contact angle test, measure the contact angle of a droplet to see how much the droplet beads up or wets out onto the surface. If when you perform the droplet test you find that the beads are quite round and do not wet this indicates low surface energy and poor bondability.

    From here you should conduct a suitable gas plasma treatment on some of the boards and see if this improves bondability and adhesion. You can bond actual parts to both the control and plasma treated boards to confirm any improvement in adhesion.

    If you are bonding to a metal surface, you should always first prep the surface with etch or alcohol. This will ensure the area is clean prior to any epoxy applications. GoKimco offers a complete lining of cleaning wipes to prep the area. Visit
