The AOI inspection library names are an important part of AOI programming as the reuse of these inspection templates can speed up the debug programming time, which can in turn improve line utilization time. Within Valor MSS Process Preparation the Master Part Library can store custom attributes that provide the ability to map each part number to an inspection template name. This could be a single attribute … Read More

My sister, as a child, learned to play the Violin. At first, this was an awful noise where even the cat would bolt out of the house straight into a torrential rainstorm rather than being within earshot. It soon developed however into a nice balanced tone, at times. I wondered whether I could do the same and started learning to play the recorder. Not a good idea. We shall say no more. My sister however, … Read More

For the past couple of months the Process Preparation team have looked to make a significant jump in capability to program Juki SMT machines. Third party solutions in the market can easily process CAD/CAM/Gerber data to create placement data to tell the Juki machine where to place the components. However, the information on the part is still needed to be manually added before the Juki software can create … Read More

Using an effective DFM analysis process, in conjunction with the ODB++ product model exchange into manufacturing, are keys to implementing a Lean NPI process within your organization. This passage will briefly examine what are the benefits behind implementing these two powerful technologies together.
The diagram below represents an evolution in DFM practices. DFM level 0 represents the most costly … Read More

Production Schedules….Scheduled! – “General Guidelines”
In this post, I’d like to review some basic guidelines that most production planners and schedulers seem to agree upon. Not meant to be the cure-all defacto standard, but based on polling several factories of various sizes and strategy seems to be a core list.
1) Plan the schedule to ensure up to 99% capacity of the bottleneck operation … Read More

“Strategic Alignment”
There are many variables the influence meeting production schedules. One of which is factory strategic alignment.
The goals of a factory are heavily influenced by the incentive programs deployed in the factory. These incentives should be driven by that organization’s competitive strategy in their markets. Are they focused on advanced technology, low-cost producer, highest … Read More

Production planning is a dynamic problem to solve, as the variables seem infinite.
As more and more global regions move to high-mix with increasing volume production, the planning task of running multiple products effectively through existing assets and resources poses a significant scheduling challenge. Manufacturing plants today are challenged with shipping the required quantity of products on time, … Read More

My blogs have talked about the advantages of running DFM analysis early in the design process where it is easier to address the issues that have been found. The Valor Division product, vSure, is the perfect solution to work in conjunction with Expedition Enterprise for example to provide that feedback. However, there is one area of DFM that can benefit from analysis that is performed with the assembly … Read More

Another area I discussed in my recent article for PCB007 was with Design For Test or DFT. Ensuring that accurate test or inspection techniques have been catered for before a layout is signed off will ensure that any assembly or component issues will be found as early as possible in the manufacturing process. For each additional step during the manufacturing process it is estimated that the cost of corrective … Read More

In a recent article for PCB007 I discussed the definition of Design For Manufacturing (DFM). As a follow up to that article I will elaborate on the discussion in terms of the solutions that the Valor Division of Mentor Graphics can provide.
For concurrent design analysis, Valor vSure provides an un-paralleled capability to work in conjunction with the layout design tool to create, not just a physical … Read More
