The following procedures explain how to properly clean and test an ESD surface.
Clean an ESD Surface
Do not use abrasive or highly alkaline cleaners on polycarbonate. Never scrape polycarbonate with squeegees, razor blades, or other sharp instruments. Benzene, gasoline, acetone, or carbon tetra chloride should never be used on polycarbonate. Do not clean polycarbonate in the hot sun or at elevated temperatures.
Using a sponge or soft cloth, wash the ESD-protected surface with either a mild detergent or Windex product and lukewarm water.
After washing, rinse with water and dry thoroughly with a chamois or moist cellulose sponge to prevent water spots.
To protect the ESD surface after rinsing and drying, recommends applying Kleenmaster Brillianize®. This application helps to maintain the static dissipative coating and reduce the accumulation of dust.
Test Static Dissipative Covers
Periodically and after maintenance, check the machine covers to determine if the dissipative qualities of the cover have changed. The following procedure ensures that static dissipative covers are in fact dissipative.
Tooling
Surface resistance meter (such as 3M 701 Surface Resistance meter and probe).
Comments
The surface resistance should be less than 109 ohms in all areas. If the cover package is no longer dissipative, contact you Universal Instruments Corporation sales representative.
Procedure
Clean the static dissipative covers using the Clean ESD Surface procedure to ensure the accuracy of the test.
Using the surface resistance meter, follow the instructions provided by the manufacturer to measure the surface resistance of both the inside and outside of the covers. Measure the resistance at all four corners and at several areas in the middle of the cover. This test checks the integrity of the ESD coating.
Connect the ground path resistance probe to the meter and chassis ground.
The path to the ground should not be higher than the surface resistance. If it is, clean the frame connections, repair loose or corroded fasteners and ground straps, and check tracks for dirt and/or corrosion.
4. Measure the ground path from the covers to the chassis ground. Take this measurement from both surfaces and all four corners of each cover.
While in attendance at the 2017 National Association of Music Merchants (NAMM) Show last month we found one thing to be true… THT Equipment is far from dead. The music industry continues to require robust and durable components for high quality and heavy duty gear. GEAR, GEAR, GEAR! And the better the gear the more likely THT was involved in the assembly. Proving that THT is not just surviving but thriving in our high-tech world.
But there are many missing links! Many of these specialty components are still placed by hand and many more are still IMPORTED. Opportunities abound for manufacturers to bring all assembly, quality control, and profits back home. Quality is the name of the game when it comes to being #1 in any product category but costs sometimes hold back some manufacturers. According to Joel Menchey, Menchey Music Service, import costs for audio manufacturers are the highest of all costs. This doesn’t have to be so.
We at Southern Machinery have the solutions to lower costs and improve your manufacturing assembly quality! Our S-600-OF Through-hole & Surface Mounting Multifunction Machine paves the way to incorporate THT with SMT technologies. We can help you design the exact machine for your needs, ordered to spec. It’s a simple conversation for a huge shift in ideology and savings.
Huge Component Range: places SMDs from 0402 to 15 mm x 15 mm, including resistors, capacitors, inductors, diodes/ audion , IC, SOTs, SOPs, QFPs and CSPs, and THT components.
Feeder racks can accommodate a mix of tape feeders and IC tube/stick feeders or 5 THT components feeder.
Teaching/fiducial recognition camera for easy programming & operation
Customized nozzles available.
Bottom fixed-camera vision system for fast, accurate alignment.
Ball screw drive and heavy-duty, uni-body construction ensure smooth, high-speed movement and high accuracy and repeatability.

Avoiding Design Mistakes with Testing
Improve EMS Productivity by Testing Early
PC Board errors are a drain to EMS productivity. Through analysis and testing PCBs in the pilot stages, a smoother and more educated production set-up can be achieved. By performing automatic impedance measurements and testing of components (chip resistors and capacitors) early on, you can ensure the best design for production.
We recommend applying the best design logics when creating your PCB layout and Test, Test, Test for maximum efficiency and output. According to Circuits Assembly’s December 2016 Magazine, here is the list of 5 Most Common PCB Design Mistakes: “1. The components do not suit the production technology 2. Thermal imbalance 3. Incompatibility between fabrication and assembly technology 4. Component placement at PCB edge 5. Placing fiducials on the PCB’s edge.”
Once you have planned your PC Board with best practices, Southern Machinery’s High-Speed In-line Circuit Board Test Machine will help with testing by incorporating a visual inspection function which allows mounting status checks on each component (e.g.: typo descriptions in alphanumeric characters, orientation, size) on the operator’s monitor will serve to best analyze testing up close. As well as automatically generating test data from mounting data and component list.

Continue with the next step after the drivers are updated.
Calibrate the PEC camera and lighting. For instructions, see the PEC Calibration: Camera and Lighting (Multifunction Machines) help topic in Voyager.
The PEC camera consists of two elements: a rotating polarizer that covers four of the eight illumination petals and a sliding polarizer. The sliding polarizer is located in the camera aperture. The axis of this polarizer, frequently referred to as the “analyzer”, is orthogonal to that of the rotating polarizer. The combination of these polarizers on the module results in cross-polarized illumination.
(Typical PEC Camera shown)
The rotating polarizer ensures that the substrate is illuminated with linear polarized light. The metal features and ceramic background reflect polarized light differently. The light reflected from the metal has no net change in polarization. Because the orientation of the sliding polarizer located in the camera aperture is orthogonal to that of the rotating polarizer, most of the light reflected from metal features is blocked. Therefore, metal features appear dark on the camera.
In contrast, the ceramic surrounding the metal features randomizes the polarization upon reflection. Because the polarization is randomized, a portion of the reflected light can pass through the central polarizer and reach the camera. Therefore, the ceramic background appears as a shade of gray.
The following table summarizes the polarization effects on metals and ceramics:
Material
Incident Polarization
Reflected Polarization
Central Polarizer Orientation

Polarized Lighting Zones
The PEC Lighting Assembly has two lighting zones. Which zones are used for imaging depends on the type of substrate being imaged. The two lighting zones are shown in the table below.

Zone I
Blue
Zone II
Red
Petal Zones I and II each contain four illumination petals positioned at 90 degrees to each other. The illustration below shows how the Red (R) and Blue (B) LEDs are oriented.
Selectable Polarizer Positions
The PEC Lighting Assembly is equipped with a rotating polarizing filter and high intensity LEDs. The PEC camera has a polarizing film mounted within a rotating ring and a second polarizer mounted on a slide above the lighting module. Certain classes of flexible circuits image well with cross-polarized illumination. For the polarized option, it is recommended that the central polarizer be left in place.
The blue lighting zone of the PEC Lighting Assembly is designed to image flexible circuits.
The red lighting zone of the PEC Lighting Assembly is designed to image ceramic circuits.
The following table summarizes the available Polarized lighting options:

Function
Zone I
Orienting the rotating polarizer above the blue LEDs allows non-polarized illumination from the Red LEDs. This lighting type is effective on dark-colored ceramics.
Zone II
Orienting the rotating polarizer located above the red LEDs allows polarized illumination from the Red LEDs. This lighting type is effective on white or light-colored ceramics.
After many requests, we are thrilled to announce our Industry Leader Newsletter. As an Industry Leader, Southern Machinery wants to provide your company with the same excellence we put into our equipment and services. We know your job is important and you must always stay ahead of trends in PCB Assembly. Changes in labor costs, shifting environmental laws and policies, energy conservation efforts, advancing industries, international trade politics, etc., are causing a reemergence of in-house manufacturing systems to be put into place. The tide has shifted and it is now time to begin transitioning to a more self-sufficient manufacturing system.
