Embedded processors are the sweet spot of the network market for task-specific solutions,” Sauerwalt said. However, we don't have on the IBM roadmap any plans to put embedded processors in blades ourselves.”

Indeed, the cost of breaking lots can outweigh the savings associated with the smaller buy, according to Craig Conrad, executive vice president of sales and marketing at distributor TTI Inc., Fort Worth, Texas. A partial shipment, for example, could save an OEM $1 but wind up costing the distributor $20, Conrad said.

Customers need to look at the cost of the reel vs. the number of parts,” he said. The extra might be cheaper to discard if the OEM doesn't plan to use the items again. The cost to shelve the inventory, count the inventory, and then re-label the inventory could be more than the cost of the reel itself.”

Fiscal headacheStill, small-lot buys are an important part of the purchasing and materials sourcing strategy for Sonic Manufacturing Technologies, a $20 million EMS company in Fremont, Calif., that specializes in quickturn prototype production.

For Sonic, the process of buying full reels, which can cost as little as $20 depending on the component, hasn't caused too much pain, according to David Ginsberg, vice president of supply chain management. However, when it comes to higher-end chips and interconnects that can cost upward of $100 and come in trays of 48 or 96, the minimum buy can be a fiscal strain.

We look for broken quantities where we can, especially when it comes to ICs and connectors because those are the most expensive parts,” Ginsberg said.

LeeMAH Electronics Inc., a small EMS provider in San Francisco, said it faces the same problem and buys parts from distributors in pre-determined lot sizes dictated by the supplier. LeeMAH spends $30 million to $50 million annually on electronic components, boards, and plastics.

Nearly 60% of the material purchased is through distribution, according to Ken Murray, LeeMAH's supply chain manager, who said he doesn't believe his company has the buying power to influence its larger distributors or suppliers.

You have a better chance buying partial reels from a smaller distributor, because the larger ones say breaking the packages adds to their labor costs,” Murray said. We accept the practice rather than push the distributor.”

Figure 37 shows the uncorrected tweeter response (blue) and the shaped tweeter response (red).

Table 7 contains the filter descriptions used to develop the tweeter response. The tweeter low frequency response is shaped by the 3600 Hz second order Linkwitz Riley high-pass plus the 2000 Hz bass shelf filters. The high frequency response of the tweeter is shaped by the 3000 Hz treble shelf and the 18939 Hz equalization filters.
