Can Your Contractor Really Help Your Team Build Better Product?

Many companies assume that regional electronics manufacturing services (EMS) providers are more focused on building product, than helping customers build it better. That couldn’t be farther from the truth at Burton Industries. Engineering strength is one of one of our key advantages. For over 35 years, our team has been telling customers to ‘bring it on.’ Here are few examples of the problems we’ve solved:

Cost Reduction teamcrop

Many of our customers face competitive cost pressure but have limited redesign options. Our team can help. For example, in one measurement device product line we were able to apply our value engineering skills and reduce the cost of three assemblies by 12, 14 and 16 percent, respectively. The cost savings was achieved through a combination of identifying drop-in replacements for several components and eliminating some manufacturing processes.

Failure Analysis

In another case, we helped a customer address a field return issue on a system controller. Our engineering team performed failure analysis on the field returns using an outside laboratory and found no issues with the components. Further analysis showed that the problem was in the customer’s documentation. On the same assembly, a customer-initiated ECO had changed a component in error and created performance issues in the assembly. Our team worked with the customer’s team to evaluate and re-layout the board. The re-layout of the board corrected the design issues and reduced unit cost by $7.87.

Manufacturability

When a customer transferred an industrial product subassembly from another contract manufacturer, we found that design for manufacturability (DFM) analysis had never been performed. Not surprisingly, the product had a history of quality issues. Our analysis found incorrect land patterns and spacing, incorrect hole sizes, slot dimensions and locations that were missing. Components were also placed too close to the PCB edge.  We were able to re-layout the printed circuit board assemblies (PCBAs) to correct these issues.

Legacy Product

In yet another case, a medical OEM had a legacy product that needed redesign support. Our engineering team worked with customer’s engineering team to gradually convert the older PTH product to SMT, and provide DFM/DFT recommendations. The end result was more manufacturable product and improved component availability.

These are just a few of the many challenges our team solves on a day-to-day basis. We stand ready to provide a wide range of engineering support, including: design for manufacturability and test recommendations, smooth new product introductions, product lifecycle management recommendations, cost reduction suggestions and test strategy optimization.

Reducing Test Cost – Five Areas to Evaluate

Is product testing costing more than it should? That is one of the first questions test engineers at Burton Industries, Inc. ask when evaluating new projects. Printed circuit board assembly (PCBA) complexity, project volumes and defects per million opportunities (DPMO) estimates all factor into what tests should be required.  But here are five key areas to check in analyzing whether or not there may be opportunities for cost reduction:_FBP4942

  • Can a faster tester be used? Case in point, Burton Industries’ CCI automated functional test platform reduces typical functional test time from 5 minutes to under a minute, over older similar functional test platforms.
  • Can NRE be reduced through use of connector-based testing? The CCI functional tester can use either bed-of-nails fixtures or do connector-based testing, provided the PCBA design allows test access via the connector.
  • Has the product been evaluated for the best test and inspection strategy? Burton Industries’ team analyzes the right mix of inspection and test steps for each customer’s goals. The Company’s current inspection and test capability includes automated optical inspection (AOI), 2D x-ray inspection, a Checksum manufacturing defect analyzer (MDA) tester, in-circuit test, automated functional test and custom functional testing, providing a wide range of options in inspection and test step combinations.
  • Are test point accessibility issues driving higher cost? In-circuit testing can cut test costs in higher volume PCBA manufacturing when the PCBA is accessible enough to ensure good coverage, however, when that isn’t the case the solution is often greater levels of inspection or longer functional test cycles. Self-tests such as boundary scan testing can help improve test coverage in PCBAs with limited test point access. To achieve maximum benefits boundary scan cells need to be included on all pins.
  • Is there a final program, test, pack and ship station? Combining testing and programming can save some time over separate processes. Having that work cell also pack and ship the product enhances configuration management by minimizes the opportunity for mislabeling or mispackaging products that are configured to order.

The team at Burton Industries is focused producing products at the lowest possible costs and routinely evaluates these areas to better optimize test strategy.
