Software Provider Considerations
There are some important as-
pects to consider when selecting a TTC software provider. While there may be numerous companies that of- fer this ability, not all of them can pro- vide it to a customer’s specific stan- dards. When searching for the TTC provider that best fits your company’s individual needs, consider the compa- ny’s stability. Also, make sure that it provides an open source database for data mining and understands the long-term cost for adding people and equipment. Finally, be sure to ask about its roadmap for new releases. Staying up-to-date with new systems and technologies is a big part of the software’s traceability rates.
Open Platform An open platform format pro-
vides users with increased flexibility as well as the ability to purchase best- in-class tools and then integrate them into the platform. These are several types of manufacturing software which fall into the general category of manufacturing execution systems (MES). At one end are highly flexible development platforms that provide the plumbing without any accessories. Each user has to develop individual applications and is left with the diffi- cult task of collecting data from the manufacturing line and populating the MES database with accurate data.

dor must be contacted and the EMS provider must adhere to whatever cost and lead time they ask for, and this happens only if they are even willing to quote it. In between these two extremes is the ideal compro- mise: a solid platform, including both TTC hardware and software, with a good set of applications that are highly configurable, and a series of open interfaces for third-party devel- opment. This provides several op- tions to the user when it has unique
C CableEye
Whether you're an R&D engineer designing cables for a new product or a production worker checking hundreds of cables an hour, Cable- Eye's unique graphic wiring display tells you what you need to know clearly and immediately. Graphically see missing or shorted conductors, miswired cables, reversed diodes, and backward connectors. Print crystal- clear test results including the wiring schematic. Graphically compare two cables by alternating the display between your test result and the ideal cable. Run a high-speed resis- tance test loop while you flex the cable to check for

historical database. In a real-life sit- uation, this approach proved to be much more successful than the alter- native MES solutions that were im- plemented in the past. The system was up and running in less time, at a lower cost, and all the expected func- tionality was achieved within in a few months.
ROI with RFID In some applications, RFID can
replace or complement barcode tech-
This first approach provides the ulti- mate flexibility but also the highest cost of ownership. At the other extreme are highly
specialized and fully developed MES solutions that do not require any software development and cus- tomization. The problem with this approach is that there is no flexibili- ty to adapt to specific customer re- quirements. Each time that a small change is needed, the software ven-
requirements. The user can buy from the software provider, develop with internal resources or hire a third- party developer to take care of it. In the case of ACD, the compa-
ny ultimately developed some of the machine interfaces internally, using the standard IPC CAMX protocol that is supported by its TTC system. It also developed several reporting tools, including a customer Web por- tal, by accessing the data in the TTC
nology to provide a higher level of au- tomation. This removes the need for an operator to scan a barcode label, thereby saving time and further re- ducing the risk of human errors. ACD is using RFID tags on tape
feeders and other types of tooling like stencils. This removes the need for operators to scan barcode labels on the feeders and feeder slots when they load feeders on trolleys. Additional benefits include ac-
curate, fast offline setup, reduced machine downtime and reduced chance of human error, especially with swapping components. Another important benefit is the fact that it makes the TTC system more user- friendly, thereby increasing its ac- ceptance by line operators. The TTC solution can cover all
material, including PCBs, electronic components, tooling, and consum- ables — all the way from receiving to shipping. Implementing real-time TTC at the shop-floor level allows users to identify and correct errors before a defective product can be pro- duced. This results in reduced de- fects, reduced product variability, in- creased first-pass rates, improved yields and reduced waste. Contact: ACD, 1250 American
