‘Can Do’ in CAM Outsourcing: Improving Quality in CAM Engineering

In this series, I will address six ways in which a company can significantly benefit from outsourcing their front-end CAM work:

  1. On-demand capacity
  2. Improving automation
  3. Fast turn-around
  4. Reducing costs
  5. Improving quality
  6. Building redundancy in critical areas

This column will focus on the fifth benefit: improving quality.

Improving Quality

One of the hallmarks of achieving and maintaining high quality is having a controlled process. However, the main challenge of attaining a repeatable process is that different individuals tool complex jobs—especially when it is possible to complete the same job in multiple ways. Many companies have a tremendous amount of tribal knowledge in the heads of a few key people who execute tooling jobs using their own unique methods. This occurrence often leads to huge problems when the individuals leave the company because their tribal knowledge walks out the door with them.

The key to achieving repeatable processes is using automation and developing systems that allow tribal knowledge to be captured using a formal approach. For example, in our facility, the goal is to fully automate the entire tooling process. Moreover, focusing on improving quality can affect other critical areas of the business. Better systems result in faster turn-around times and reduced costs. One of William Edwards Deming’s 14 points for management states, “Improve constantly and forever the system of production and service to improve quality and productivity, and thus constantly decrease costs.”

Therefore, it is essential to work with an outsourcing partner that solves problems with a systems-based approach. It can be easy to throw bodies and resources at a problem and hope it will be solved—especially if you’re based in a low-cost region. However, this usually leads to more issues. When it comes to tooling and CAM, the solution is to develop scripts and automation. Maintaining automation over time is critical. Some people don’t create automation in the first place, and a majority of others don’t keep it updated due to a lack of commitment to quality. In an environment where scarce resources get pulled into fighting fires and keeping up “hot jobs,” there isn’t enough time in the day to devote to systems and automation.

Partnering with the right outsourcing partner can help. Systems and automation can be developed and used by the outsourcer and have a significant impact on your workforce. Plan to use the same systems and automation for your engineers. Entering into a partnership where the outsourcing partner becomes an extension of your engineering team is extremely beneficial. As they work on new jobs alongside your employees, they should keep a finger on the pulse of your changing requirements and adjust the systems and automation on a regular basis. By doing so, you can avoid the systems and automation becoming outdated, which can lead to people returning to using tribal knowledge and manual processes.

Another tool from William Edwards Deming is the Deming Cycle—a four-step management method for continuous quality improvement of processes and products. It’s referred to as the plan-do-study-act (PDSA) cycle. The PDSA cycle should be employed when undergoing a systems/automation quality improvement program. The steps are as follows:

  • Plan: Assess current and future states and identify alternative solutions for how to close the gaps
  • Do: Try or test the solutions (sometimes at a pilot level)
  • Study: Check to see if the tested solutions accomplished the objective
  • Act: Request corrective actions for significant differences between the actual and planned results, and analyze the differences to determine the causes
  • Repeat the cycle


In summary, using an outsourcing partner can help improve quality by allowing you to:

  • Implement repeatable and consistent processes
  • Reduce or eliminate reliance on individuals with tribal knowledge  
  • Streamline and systematize your entire front-end process
  • Reduce shop floor rejects through improved front-end quality, which results in lower costs and higher margins
  • Easily add and train new employees with better processes and systems
  • Capture more market share from your competitors  
  • Free critical engineering capacities to help generate more technical sales and have more customer interactions
  • Grow your business and have scalable front-end resources to fulfill your changing requirements

CAM Engineering—Reducing Costs


While having on-demand capacity, improved automation, and fast turn-around are critical to any front-end engineering operation, achieving those goals with a cost-effective solution is imperative. Electronics are constantly under cost-reduction pressures. Functionality, capability, and complexity increase while costs decrease.

CAM Engineering—Fast Turn-Around


Time-to-market has been the mantra for every successful technology company. The best among them have strong and integrated supply chains that march to the drum of the OEMs and EMS providers that bring that technology to market. A big part of that success, especially in North America and Europe, is the ability for PCB manufacturers to turn around complex PCBs very quickly. The hallmark of PCB production in these higher-tech, higher-cost regions is flexibility and responsiveness.

CAM Engineering – Automation


As volume production in PCB has shifted significantly to Asia, manufacturers in Europe and North America have been focusing on high technology, quick-turn, prototype, and lower-volume production.

A Case for Outsourcing CAM Engineering


In the West, outsourcing is sometimes considered taboo and many believe it is one of the causes for shifting our manufacturing base to the East—specifically China and other lower cost Asian countries. In this series of columns, I will make a case in support of CAM outsourcing—especially for North American and Western European printed circuit board manufacturers.
