			<content:encoded><![CDATA[<p>Indianapolis, in, August 18, 2009:  Diversified Systems, Inc. (<strong><em>dsi</em></strong>) added ITAR to its list of certifications and registrations this month.  ITAR, International Traffic in Arms Regulations, governs the development, manufacture and export of defense articles and defense services, as well as related technical data. One of <strong><em>dsi</em></strong>’s key market segments is the military / aerospace sector.  With the addition of ITAR, <strong><em>dsi</em></strong> again reinforces its commitment to hold the Quality Certifications, Registrations and Performance Standards for every market <strong><em>dsi</em></strong> serves.

<p>Diversified Systems, Inc. is an electronic contract manufacturer (board level through full box build) of high reliability products, with a foundation based on engineering methodology. The commitment to quality is evident in the sheer number of certifications / registrations held by <strong><em>dsi</em></strong>, including: ISO 9001:2000, AS 9100 Rev B, ISO/TS 16949, TL 9000 Registration Rev 4.0, ITAR Registered, and internal trainers certifying operators to IPC Manufacturing Guidelines (IPC-A-600 &amp; IPC-A-610), J-STD-001, IPC-7711/21.  More information on <strong><em>dsi</em></strong>’s Quality focus can be found at www.divsys.com.</p>

			<content:encoded><![CDATA[<p>dsi is your single source for rapid pre-production assemblies. We offer assemblies in 2 to 3 business days — made to production quality standards!</p>
<p>Need help procuring components for your rapid build? Our highly trained project management staff  can electronically source components for you. You can also take advantage of dsi’s in-house inventory of over 30,000 different part numbers.</p>
<p>After you have validated your boards and assemblies, let us provide a seamless transition from the prototype stage to full production.  Since dsi uses the same lines for Rapid jobs as we do for production jobs, the transition is smooth and simple.  And, if you are moving to high volume production assembly, dsi can make the transition to one of our off-shore partners.  Your IP will be secure, and you will have the comfort of knowing that dsi is verifying your units at our Indianapolis facility before they ship to you.</p>

<div><span style="font-family: arial,helvetica,sans-serif;"><strong><span style="font-size: 10pt; color: black;">Presented By:  Stan Bentley-President/Owner, Diversified Systems </span></strong></span></div>
<p><span style="font-family: arial,helvetica,sans-serif;"> </span><span style="font-family: arial,helvetica,sans-serif;">The assault on manufacturing in the US began a long time ago. The manufacturing base was so large and so diverse, that the impact was not quickly recognized. There was no single contributing factor. In fact, each industry was faced with somewhat different circumstances. Automotive was plagued with work rules that drove up the cost of labor. Electronics was impacted by the extreme cost of capital equipment and tax rules for depreciation. Consumer goods often had large amounts of hand labor, making them unprofitable when minimum wage laws were applied. While the list goes on, the real culprits were too very different forces: Corporate greed, and consumer thrift. Corporations were driven to extract higher profits while consumers demanded cheaper prices. The impact of these forces has not abated. The end result is an assault on manufacturing.</span></p>

These guidelines do not represent <strong><em>dsi</em></strong>&#8217;s full capabilities       (such as smallest hole size, tightest spacing, and so forth). Rather, they       indicate the tightest tolerance for which optimum pricing can be provided.       The layout guidelines, when followed, will reduce or eliminate the need       for non-standard processes and their associated costs.</span> <strong> </strong></p>

<tr>
<td align="left" valign="top"><span style="font-family: Arial,Helvetica,sans-serif; font-size: x-small;"><strong>Vias: </strong>Annular rings should be maximized wherever feasible.  Annular ring of VM = (pad diameter &#8211; hole 	 				      diameter).  Annular rings less than 0.010&#8243; may violate IPC&#8217;s minimum annular ring requirement. 	 				      Also, make sure the cross sectional area of the via is equal to or greater than the cross sectional 	 				      area of the trace connected to it. See &#8220;Trace widths vs. via sizes&#8221; section for the formulas 	 				      used to calculate cross sectional area.</span></td>

<tr>
<td align="left" valign="top"><span style="font-family: Arial,Helvetica,sans-serif; font-size: x-small;"><strong>Thru 	 				      hole pads: </strong>The optimum pad diameter for a thru hole component is twice 	 				      its finished hole diameter.</span></td>
</tr>
<tr>
<td align="left" valign="top"><span style="font-family: Arial,Helvetica,sans-serif; font-size: x-small;"><strong>Trace 	 				      width and conductor spacing:</strong> The current minimum trace width is 0.003&#8243;. 	 				      The current minimum conductor spacing is 0.003&#8243;. Remember, the smaller 	 				      the trace and space, the larger the amount of scrap. Anything larger than 	 				      0.007&#8243; trace and 0.007&#8243; space is reasonable enough to keep the 	 				      scrap to a minimum.</span></td>
</tr>
<tr>
<td align="left" valign="top"><span style="font-family: Arial,Helvetica,sans-serif; font-size: x-small;"><strong>Silk-screens:</strong> The thinnest line width that can currently be silk-screened is 0.008&#8243;. 	 				      Typically a line width of 0.010&#8243; is used for component outlines. The 	 				      smallest readable text size is 0.050&#8243; character height with 0.008&#8243; 	 				      line width. Any smaller than this and the text will not be readable. If 	 				      a component is known to be mounted on the bottom side without a bottom side 	 				      silk-screen, a dashed component outline will be displayed on the top silk-screen 	 				      to show component orientation. Silk-screens should never be placed on top 	 				      of an exposed pad. A minimum of 0.010&#8243; spacing is recommended between 	 				      silk-screen and pads.</span></td>
</tr>
<tr>
<td align="left" valign="top"><span style="font-family: Arial,Helvetica,sans-serif; font-size: x-small;"><strong>Finished 	 				      hole sizes: </strong>To determine optimum finished hole sizes for leads, add 	 				      0.008&#8243; diameter to the maximum possible lead diameter. For boards designed 	 				      to be assembled by DSI&#8217;s auto inserter, the optimum finished hole size is 	 				      the maximum possible lead diameter plus 0.016&#8243;. PCB&#8217;s with the smallest 	 				      finished hole size larger than 0.025&#8243; in diameter can be drilled three 	 				      at a time. All other boards are drilled one at a time.</span></td>
</tr>
<tr>
<td align="left" valign="top"><span style="font-family: Arial,Helvetica,sans-serif; font-size: x-small;"><strong>Fiducials</strong>: 	 				      Any side of a PCB with surface mount components should have a minimum of 	 				      three fiducials. The ideal fiducial for DSI&#8217;s pick and place machines is 	 				      a 0.040&#8243; diameter pad with a 0.080&#8243; diameter or more solder-mask. 	 				      Fiducials should be placed as far apart as possible and clear of any traces, 	 				      mounting holes or silk-screens. The outer corners of the board are the ideal 	 				      placement.</span></td>
</tr>
<tr>
<td align="left" valign="top"><span style="font-family: Arial,Helvetica,sans-serif; font-size: x-small;"><strong>Solder-mask:</strong> The typical solder-mask is a 0.005&#8243; annular ring around every pad except 	 				      fiducials. e.g. If the components pad is 0.060&#8243; diameter then its solder-mask 	 				      should be 0.070&#8243; diameter.  For fine pitch components (0.5&#8243; mm with 0.009&#8243; between pades), use a 0.003&#8243; annular ring.</span></td>
</tr>
<tr>
<td align="left" valign="top"><span style="font-family: Arial,Helvetica,sans-serif; font-size: x-small;"><strong>Solder-paste:</strong> Typically the dimensions of the solder-paste area should be the same as 	 				      the dimensions of the surface mount pad it is applied to. Custom dimensions 	 				      may be used in special cases.</span></td>
</tr>
<tr>
<td align="left" valign="top"><span style="font-family: Arial,Helvetica,sans-serif; font-size: x-small;"><strong>Board 	 				      outline:</strong> A 0.010&#8243; line width should be used to draw the board outline. 	 				      The board outline should always show the ideal board shape, even if it is 	 				      not cost effective to route the board exactly as the board outline shows. 	 				      For example, zero radius internal corners are difficult to route. Therefore, 	 				      all internal corners can be drawn with a zero radius but must have a minimum 	 				      radius specified. Any radius 0.0465&#8243; or larger (0.093&#8243; router 	 				      bit) is considered to be cost effective. Using PCAD layout software, the 	 				      board outline is typically drawn on the BOARD layer. When creating gerber 	 				      files for manufacturing, the board outline should be included on every artwork 	 				      to give the artworks common features for alignment.</span></td>
