Why SMT? How to EMS?

Why SMT?

Manufacturers continuously evaluate new components and systems technologies in terms of reducing size, increasing design flexibility, improving reliability and reducing cost for systems. SMT satisfies all these requirements. It can provide size reductions of over 40%, assembly cost reductions of almost 50%, and can enhances the performance of electrical circuitry [Lea, 1988].

SMT Reduces Size and weight

The increased density of components can lead to a higher functionality in the same space. This allows the system manufacturer to price differentiate his product in the market by carefully choosing his components.

  • SMT components require less circuit board area and volume than their through-hole equivalent.
  • Components can be mounted on both sides of boards.
  • Lighter components with the same functionality can be significant in the

    aerospace industry as well as portable consumer electronics.

    SMT Increases Performance

  • SMT offers better interconnectivity due to shorter paths, providing lower inductance and capacitance.
  • SMT reduces the package propagation delay, which is the time the signal needs to move from one component to another. Typically the longest delays in the system are off-chip.
  • Electromagnetic interference can be decreased by combining sensitive circuits on a single board and improving its Electromagnetic Induction (EMI) shield design.

    SMT Improves Reliability

  • The smaller and lighter construction of SMC’s allow them to resist shock and vibration better than their through-hole counterparts.
  • The reduced number of PCBs and connectors improves overall reliability at the system level.
  • However, SMT systems require careful attention to mechanical design to avoid overstressing the solder joints.
  • The demanding nature of the SMT process has resulted in extensive automation and corresponding increases in product quality.
  • SMT Reduces Cost

    • Bare Boards
    The use of SMT, typically, results in smaller area PCBs being used due to the reduction in the size of the components being used. In general for two functionally equivalent PCBs, one utilizing surface mount and the other using conventional through hole, the larger the PCB, the more expensive it will be. Increased density on an SMT board generally requires multiple layers as well as smaller line widths and spacings to accommodate the finer pitch components and smaller hole diameters to interconnect the layers. The only time a hole is required is to carry the signal to another layer whereas with through hole components there must be a hole for each lead of each component. In some cases through hole PCB’s may require more layers because there are more larger holes which means there will be less room on the inner layers for circuit routing increasing the layer count.

    • Processing

    Surface mount components have almost all been designed for automatic assembly. Many unusually shaped, through-hole components, called odd- formed components, which were designed for hand assembly, can now be placed automatically as well. Automated assembly of surface mount assemblies can be done using one flexible automated placement machine whereas several machines may be required for the various through hole components.

    As more types of components become available in a surface mount format, correspondingly fewer components are available in through-hole configuration forcing the cost of many SMC devices down. While through-hole components can be automatically inserted, the combined equipment, floor space and processing costs are higher.

    • Factory Operating

    Fewer types of assembly machines are required for an SMC assembly line and they often requires less floor space. Automated SMT assembly lines are considerably more productive than PTH assembly tools. Thus throughput is raised considerably with SMT manufacturing and the cost per unit of assembly is greatly reduced.

    SMT Increases Flexibility

    • SMT provides a wider range of packaging possibilities than insertion mount technology.
    • SMT allows for the use of both surface mount and insertion mount devices in the same assembly.

    SMT Eases Handling And Storage Space Needs

    Surface mount components are easy to handle due to the various storage formats in which they are shipped and presented to the pick and place machines. Tape and reel, cartridge, sticks, magazines, and matrix trays allow effective and safe handling and shipping. The storage formats have the following features:

    • Large number of components per packing unit resulting in less frequent loading of the tools.
    • Small amount of packing materials per component resulting in lower shipping and inventory costs.
    • Protection against transport and handling damage.
    • Standardization, Definite orientation of the components.
    • Protection against electrostatic discharge resulting in fewer defective systems

      and rework.

    • Compatible with highly automated equipment.

      Electronic Industry Organizations and Groups

      Uniform Standards for Surface Mount Technology are still under development in the USA, Europe and Japan. Although much has been accomplished, there is still no single set of industry guidelines. However, efforts are being taken to resolve this problem. For example, there was inconsistency in the standards set by the IPC and the EIA. As this was recognized, they have joined forces to set up a council called Surface Mount Council, to coordinate the various standards between the users and the developers of these standards. These documents have a J-STD- xxx designation. Moreover, other organizations like the International Microelectronics and Packaging Society (IMAPS) are working together on the technical issues in the PCB industry. These developments are promising and should lead to a common industrial standard in the near future.

      IPC- Association Connecting Electronics Industries

      Internet: www.ipc.org

      In 1999, IPC changed its name from Institute of Interconnecting and Packaging Electronic Circuits to IPC. The new name is accompanied with an identity statement, Association Connecting Electronics Industries.

      IPC started in 1957 as the Institute for Printed Circuits. As more electronics assembly companies became involved with the association, the name was changed to the Institute for Interconnecting and Packaging Electronic Circuits. In the 1990s, most people in the industry could not remember the name and/or didn’t agree on what the words in the name meant. In addition, the leaders from government or other business groups could not understand the name either.

How to maintain Auto Insertion and SMT machine — ESD Cleaning and Testing Procedures

Procedures and Adjustments


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.

  1. Using a sponge or soft cloth, wash the ESD-protected surface with either a mild detergent or Windex product and lukewarm water.
  2. After washing, rinse with water and dry thoroughly with a chamois or moist cellulose sponge to prevent water spots.
  3. 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.


Surface resistance meter (such as 3M 701 Surface Resistance meter and probe).


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.


  1. Clean the static dissipative covers using the Clean ESD Surface procedure to ensure the accuracy of the test.
  2. 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.
  3. 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.

THT Thriving in Specialized Music Industry

THT Thriving in the Pro-Audio Industry

NAMM Show 2017

NAMM THT Music Industry Odd-form automation machines PCB Boards

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.

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.
