101 ways to use the Valor Parts Library (VPL)

Okay, well maybe that is a little bit of an exaggeration but there are still many ways to leverage the manufacturer specific package data from the VPL throughout the Process Engineering flow.

As a follow up to my last posting I mentioned that I would be talking about the creation and use of manufacturer specific packages. Through the use of the VPL, manufacturer specific packages can be downloaded and used in many ways throughout the Process Engineering flow of vPlan.

For example, they can be used for the basis of a number of Design For Manufacturing (DFM) tests that determine the potential issues in getting new products through the manufacturing processes. As each package varies from manufacturer to manufacturer, it is important to know which package is being used in case this difference is sufficient to cause issues in production. Another key analysis test is being able to use the precise pin terminus area and see how it fits in the actual land-pattern area of the PCB. In some cases one specific manufacturer of part may have insufficient clearance to the edge of the copper compared to others on the Approved Vendor List. It is also common that the error is more significant than that with the cause being the wrong selection of part by the component procurement. Both these tests are available in all areas of the Valor DFM solutions including the vPlan Process Engineering product suite.

These same manufacturer specific packages can also be used today in vPlan for the programming of SMT equipment. vPlan stores SMT vendor independent packages in the form of vShapes. These vShapes can be automatically created from the VPL downloaded parts. Then, depending on which machines are in the production line, these vShapes are translated in to the specific SMT vendor’s part data format for programming the line. This provides significant benefit in centralizing the many machines libraries typically found on each SMT machine.

With the introduction recently of CAMCAD for Test and Inspection Engineering, we will soon be able to read these same VPL packages as part of the Design For Test (DFT) analysis performed in an upcoming release of the vPlan product. Taken collectively, the vPlan product suite is able to leverage benefit from these manufacturer packages in a number of areas.

I’ll be posting another discussion shortly on being able to sequence production build orders, run what-if scenarios and being able to quickly react when part shortages impact future production with a new product from the Valor Division.
