However, for those without this start-up experience, the Electronics Manufacturing Productivity Center (EMPF) can provide the kind of hands-on exposure to make a fresh factory start-up a smooth and trouble free operation. As a working factory and stationary trade show with over 60 pieces of equipment, the EMPF provides an opportunity to examine individual items of equipment and more importantly, how to lay-out and assemble all the equipment into a modern and efficient assembly line. Tours of this facility are free and complementary to those people in the trade.</p> <p>There are several reasons companies choose to install their own production lines. There is more control of production scheduling, direct quality control of the all the processes, and higher security than when a product is out-sourced. Build speed is quicker (a prototype line can produce a populated board in half a day) and time to market is shorter when you control the production facility. In contrast, job shops and contract manufacturers have little financial incentive to set-up and run small jobs at the expense of the larger and more profitable production runs. </p> <p>All of the equipment at the EMPF is state-of-the art and provided by vendors for demonstration to customers. All stages of a surface mount assembly line are represented. Stencil printing, chip placement, reflow, and cleaning are some of the pieces equipment that populate the EMPF manufacturing floor. The goal of the EMPF is to provide a superior example of current machine technology and performance in each specific type of equipment category, and further to have two of every type of machine, differing in design intent, features, and markets served. The EMPF has two stencil printers, two pick and place units, two reflow ovens, and two circuit board cleaning machines, along with several rework stations and other equipment. For example, at the upper range of machine capability, the MPM Speedline stencil printer can automatically apply solder paste to the stencil, clean the stencil, and with an onboard pattern recognition system, measure the coverage of paste on the pads of a circuit board. This is a high end, feature rich machine. Other manufacturer s machines can apply paste well, but rely on the operator to inspect for paste coverage on the pads and clean the stencil. Table 5-1 lists a few equipment features to consider in the selection process.</p> <p align="center"><img src="images/table5-1.gif"></p> <p>A company considering pick and place equipment can review the capability differences of a Samsung 321 and a Manncorp MC-392. While the Samsung has four pick-up heads and can place 20,000 chips per hour (CPH), the Manncorp has two heads and can place 5500 CPH. Both are well made machines, but serve different markets and have different performance characteristics and prices.</p> <p>Reflow ovens also differ in capability, design intent, and features. With at least two reflow ovens on the manufacturing floor, the careful assessment of what features are required for a specific product is possible. The number of heating and cooling zones, computer control features, reflow profiling software, width of belt, and source of heat can all be evaluated. </p> <p>Utility requirements can and must also be considered for a new production line. Power requirements (both single and three-phase), exhaust air requirements, deionized water for a circuit board washing, compressed air, refrigeration to store the solder paste can all be estimated and planned based on the production lines at the EMPF. </p> <p>With two operating assembly lines and dozens of separate equipment items, both government and commercial companies have gained valuable experience with the variety of equipment that make up a modern assembly line.
