How We Maintain and Improve Quality Control for All Our Precision Made Parts

The industrial world today demands some of the most exacting components than it ever has before. From semiconductor microchips to military-grade aerospace parts, the advanced function that so many machines fill in our modern world all require each of their components to fit the highest standards of quality and precision. At MultiSource Manufacturing LLC, our network of multiple facilities adheres to a rigorously tested and continually improved system of quality control for all our services.

 

From precision CNC machining to plastic fabrication and more, the MultiSource network structures our contract manufacturing services on a tried and true system of quality control. The international quality standards of each industry we serve make up the foundational bulk of our quality control system while our own standards refine and improve beyond those outlined industry principles to create a start-to-finish comprehensive approach.

From the Bottom Up

With the core, foundational requirements of the global industrial quality standards in addition to our own values and goals as a contract manufacturer, the MultiSource quality control system is one that offers a quality assurance program from the bottom up. This manifests in two ways. One, with a beginning-to-end manufacturing process, and two, with a wide-to-narrow application of quality control principles.

 

  1. Beginning-to-end manufacturing: Looking at MultiSource quality control standards in terms of the manufacturing process itself, we can see that it literally starts from the bottom up. Each step of the way, beginning with design, engineering, and prototyping and ending with machining, finishing, and packaging, requires the alertness of quality control managers for the application of industry and in-house standards for quality. Because each linear step of the manufacturing process for any component has the potential to create a deviation from quality, our team is diligent in maintaining control throughout. To help us meet our quality control goals in a practical way we utilize several tools at various stages in production, including predictive prototype software, computer controlled machining, CMMs, and other vision systems.
  2. Wide-to-narrow application: To examine our quality control system with the idea that it takes on a wide or broad definition to a much more specified application is to compare and combine the industry standards with our own. For the most part, this means we implement and meet the standards outlined by the ISO and other internationally recognized groups that inspect and certify facilities and processes. Using these standards as a broader foundation, we then apply our own MultiSource in-house standards to sharpen and narrow quality control to guide each step of the manufacturing process.

 

No matter how we view the “bottom up” philosophy of our quality control, the MultiSource network strives to maintain excellence in products and services as a contract manufacturer.

Vertical vs. Horizontal CNC Milling When Fabricating Quality Components

Manufacturing in a broad range of industries utilizes milling as a versatile fabrication method. Machining mills of varying technological advancement have been in use for metals, woods, plastics, and many other materials for over 100 years. Since the 1960s, the development of CNC technology has expanded to the majority of machining operations, including milling. Milling allows for a wide spectrum of capabilities when it comes to the parts and components that can be fabricated, and MultiSource Manufacturing LLC utilizes horizontal, vertical, and multi-axis machining centers to create parts with even the most intricate designs. The network of MultiSource locations offers comprehensive CNC milling services so our customers can get the full benefits of multi-directional machining technologies.

While we provide up to 5-axis machining, MultiSource facilities have multiple vertical and horizontal CNC mills. All of our mills are on a strict preventative maintenance schedule, and despite their limitations in comparison with 5-axis machines, the capabilities of our vertical and horizontal CNC milling equipment never compromises quality in the components we manufacture.

The differences between a vertical mill versus a horizontal mill lie in their capabilities and the parts they are suited to machine.

 

Vertical Mills

The cutting spindle of a vertical CNC milling machine is placed vertically, or perpendicular to the material that will be machined. The mill height can be adjusted and the spindle itself moves horizontally. Vertical mills are typically less expensive than horizontal mills and perform simpler tasks. Vertical turret mills offer versatile milling of smaller projects as the movement of the bed rather than the spindle offers a greater range of motion. Vertical bed mills allow our technicians to work on heavy, large components with adjustable depth and movement.

 

Horizontal Mills

Instead of the cutting spindle vertical mills utilize, horizontal mills use circular cutting heads on horizontal arbors to machine components. Because of the structure of horizontal mills, they are able to use multiple cutters at different angles. This means they can provide complex, multi-sided machining of the material. Additionally, the mill can move in a wider range across the bed, allowing longer and heavier parts to be machined in one operation.

Overall, horizontal mills are more applicable to complex machining operations on a larger scale, but vertical mills have their place in machining single-side components, such as die sinking or metal plates. The MultiSource network offers vertical, horizontal, and multiple axis CNC milling with added benefits of high-speed machining, thru spindle coolant, 40,000 rpm, Renishaw probing, 84” x 33” travel, and much more.

The Importance of Wet Processing in the Manufacturing of Semiconductor Components

When it comes to semiconductor manufacturing, the fabrication process is a highly exacting and intricate one. Semiconductors require a contaminant-free space for the majority of production stages, exceptionally pure materials, and a well-engineered process. From start to finish, MultiSource Manufacturing, LLC provides comprehensive, high-quality fabrication of semiconductor components and assemblies using concurrent engineering processes, a class 1000 clean room, PFA fabrication, and much more.

Semiconductor components are highly present in today’s electronics-saturated world in the tools and devices we each use every day. From the cell phones so present in the routine of our lives to the complex computational and mechanical systems used at NASA and in the military, semiconductors have a vital role. The MultiSource network provides semiconductor components and assembly production including microchip reticle handling and purging, wafer and device handling system components, and wet processing for the primary production stages.

Wet processing is a critical stage in the manufacturing of all semiconductor components. It is during this process in which the format of the pure wafer is created. The wet processing steps are applied in the following way:

1. A resistant material is deposited into the surface of the semiconductor wafer following the engineered format desired of the final product. For the majority of semiconductors, that format is what visually creates a small roadmap of connected nodes.
2. The wafer is then submerged in or otherwise exposed to a liquid or vapor that will etch away the exposed wafer and leave behind the format of the deposited material.
3. Finally, the wafer is cleaned and inspected for quality before moving to the next stage of the manufacturing process.

While the wet processing stages of semiconductor component manufacturing is a small portion of fabrication as a whole, it’s a critical one. The wet etching and cleaning of a semiconductor wafer remains the most effective way of creating an exactly engineered format. This is also why it’s key that our team of highly-trained experts applies reverse engineering to this process as a whole. The format of a semiconductor is what makes it a functioning electronic component, and to create the correct format, our engineers must understand the desired result and work backwards to develop a solution.

With a well-versed team of engineers ready to come into the design process with the understanding of reversed development, well-made semiconductor wafers, a high-class clean room, and reliable fabrication technology, MultiSource is a trusted manufacturer of semiconductor components for OEMs and other customers.

Importance of Clean Room Standards for Manufacturing and Assembly of Semiconductor Components

Certain areas of the manufacturing operations we provide in the MultiSource Manufacturing network have very specific requirements for a controlled, contained environment during the production process. Specifically, our manufacturing of high-quality precision-based semiconductor components demands a clean room meeting exact ISO standards as well as our own self-imposed standards. The MultiSource network utilizes an ISO Class 3 clean room to eliminate the potential for contamination in every stage of the production process for semiconductor components and full assemblies.

With the protection our clean room provides, MultiSource is able to offer PFA fabrication and welding, in-house electric capabilities, and reverse engineering for even the most complex semiconductor projects.

Our Clean Room

All of our locations have access to our Burnsville facility’s clean room. This clean room meets ISO level 3 classification and Class 1 Federal Standard 209E for eliminating biocontamination and other forms of particulate contamination in the production process.

ISO 3/ Class 1 clean rooms limit the presence of contaminating particles down to:

● 1,000 per cubic meter of particles sized at 0.1 micrometers
● 237 per cubic meter of particles sized at 0.2 micrometers
● 102 per cubic meter of particles sized at 0.3 micrometers
● 35 per cubic meter of particles sized at 0.5 micrometers
● 8 per cubic meter of particles sized at 1.0 micrometers
● 0 per cubic meter of particles sized at 5.0 micrometer

This filtration of microorganisms and particles is critical for the successful production of semiconductor components and assemblies because of the nature of the materials utilized in their manufacturing. Semiconductor assemblies are derived from glassy, crystalline materials such as silicon that have an electrical conductivity decreasing in resistance as temperature increases. Because of this and other properties of semiconductor materials, they are utilized to build electrical assemblies with unique allowance for amplification and energy conversion. However, the process of building semiconductor designed for integrated circuits used in most electronic assemblies requires a highly clean environment, not only during the semiconductor seed material refinement to produce chips with complete clarity, but also during all following production and assembly of semiconductor and electronic components.

Even the smallest particle present in the manufacturing environment can, at the least, alter the quality of a semiconductor assembly and, at the most, completely damage the function of a component and the system as a whole.

With access to an in-house, high-level clean room, MultiSource engineers and technicians are able to consistently produce high-quality, precision-based semiconductor components and assemblies for OEMS and other customers.
