Trust But Verify: Process and Product Validation

By George Allman on 06 February, 2019

In wire assemblies, there are hundreds and often thousands of opportunities for defects per assembly. Therefore, it is imperative that a manufacturer takes rigorous steps to mitigate the risk of incurring those defects. Multiple process controls must be deployed to ensure that a wire assembly is produced that meets or exceeds the customer’s requirements. Many of these measures are taken before the components are even built. Revision-controlled quality requirements---specified on prints and in workmanship standards---must be understood. Operators must be trained and must demonstrate this understanding. As an assembly is produced, a predetermined regimen of tests and other validations are employed, both by operators and technicians. These validations, depending on the project, can include mechanical, electrical, and environmental tests. Each of these stages in the quality assurance process ultimately ensures that the product meets or exceeds the customer specifications.

Pursuing A Paperless Process: One Company's Journey

By George Allman on 30 January, 2019

Twenty-five years ago, Liberty Electronics’ system for creating and distributing work instructions was 100% paper-based. At Liberty, as with most companies in the industry at that time, engineers created work instructions for each assembly, printed out each document, and distributed them to manufacturing personnel. These manufacturing employees, in turn, depended on these paper documents in order to assemble components according to contract. Upon completion of an order, the documents often had to be filed for reuse at a later time.

Special Delivery: Boxing and Shipping

By George Allman on 12 December, 2018

Creating a quality product doesn’t just end with the manufacturing phase. Choosing the best packaging and shipping options to meet a client’s needs is also an important step in ensuring a product reaches the client in the same state it left the facility. Components are packaged according to specific standards and or client guidelines, and these may include special instructions or specifications, as well as quality assurance measures taken during the manufacturing and packaging process. A variety of packaging options can be used to achieve this goal, including ESD packaging and 3D-printed covers, as well as other more traditional packing products.

Marking and Identification: Product Identification Methods

By George Allman on 05 December, 2018

 

Marking and identifying the components of wire assemblies properly is an important step in the manufacturing process. Proper identification ensures that the product reaches the required certifications, while providing practical information to the manufacturer and customer about each component of the assembly. Different types of identifying techniques, including laser marking, heat-shrinkable labels, wrap markers, and printing, all offer various options for the manufacturer to meet the client’s needs.

Wire Bundle Management: Holding it All Together

By George Allman on 21 November, 2018

Making sure wire bundles are adequately secured or contained is an important step in creating a quality product, even after the necessary electrical or environmental protection has been applied. It is imperative that a wire assembly be secured adequately, and it is also crucial that the bundle fits well within the physical space allotted. This is where various wire bundle management techniques come into play. Wires can be held together using heat shrinkable tubing, lacing, stitching, tie wraps, metal bands, or braided coverings. The style and material used to secure the assembly helps it achieve the best performance possible.

Molding Materials: One Over Another

By George Allman on 14 November, 2018

Molding protects the connectors of a wire assembly from a variety of potential harmful influences. These include environmental factors such as water and chemical damage, as well as abrasion and other physical damage in service. Using the best material for the job also ensures the best possible adhesion for the components, yielding reliability and longevity of the end product. The choice of molding material used is directly related to the desired function and level of performance, and utilizing the best materials in the industry---such as urethanes , silicones, and epoxies---ensures the highest quality of assemblies according to client needs.

Understanding Insulation Materials

By George Allman on 10 October, 2018

Insulation materials provide wiring harnesses with a layer of necessary protection in a variety of ways, depending on the specific requirements the product must meet. Insulation helps protect the product mechanically, electrically, or environmentally, meeting particular needs according to the product’s application. Additionally, a variety of materials used in wiring harness insulation ensure the various functions of cable harnesses are carried out in the best way possible using the best materials for the job.

Wire Braiding: Machine Versus  Premade Options

By George Allman on 25 September, 2018

 

Braided coverings and shieldings are an excellent way to make wiring configurations neat and uniform. Braiding gives wires more flexibility and a longer lifespan and can also offer a layer of electric protection or abrasion resistance. Although there are two different types of wire braiding widely used in the industry,  machine braiding and premade (or slide-on) braiding, machine braiding offers more versatility, cost savings, and consistency, and should be something a contract manufacturing partner should be able to do in-house.
