Thin Film Conductors for Filled Vias: Copper vs. Gold

by Jaymie Murray 13. November 2014 16:43

While gold is an excellent substrate option for filled vias/plated through holes, copper has become the preferred technology for commercial packaging, hybrid manufacturers, and microelectronics providers. 

Copper vias offer better thermal conductivity and higher electrical conductivity for high reliability RF/Microwave and high power applications compared to solid gold filled vias. While the cost of gold has risen at a rate of 300% over past decade, copper continues to be an affordable, highly effective medium for thin film substrates. 

API's copper filled vias are manufactured in a MIL-PRF-38534 Class H & K facility and are fired in a nitrogen atmosphere to prevent oxidation. Diameters are available from 0.005" to 0.015" in order to fit customer needs. To learn more about API’s copper filled vias, visit micro.apitech.com/copper-filled-vias or contact us to get a quote.

Q & A with Great Yarmouth’s Test House Engineer John Ellero

by Jaymie Murray 7. November 2014 09:21

API’s Great Yarmouth facility features a UKAS accredited test house with a US Defense Logistics Agency (DLA) Laboratory Suitability approval for performing tests in accordance with both MIL-STD 883 and MIL-STD 202, making it stand apart from other test houses in Europe. In this Q & A, John Ellero, Great Yarmouth’s Test House Engineer, explores what other attributes make our test house a unique proposition to our customers.

Q: What are some of the climatic tests that we perform?

A: We run a variety of environmental tests, including extreme high (250°C) and low (-65°C) temperatures, temperature cycling (gradual and/or thermal shock), humidity, vibration, and mechanical shock. Depending on the environment that the product will be used in, we may also do a combination of these tests. While the details of a certain set of specs may vary, the fundamental tests that we perform remain the same. What really sets us apart from other test houses are the variety of testing methods we offer coupled with the combination of approvals and certifications we have earned.

Q: The Great Yarmouth test house has had DLA Laboratory Suitability approval for MIL-STD 883 and MIL-STD 202 test methods for 25 years, has been accredited by the UKAS for the past 30 years. How difficult is it to achieve these approvals, and what does the process entail?

A: These approvals all have different sets of stringent requirements that are measured during the auditing process. The UKAS focuses more on our technical capabilities, whilst the DLA makes sure that we fully understand all of their numerous requirements. The fact that we believe we are the only test house in Europe to simultaneously hold UKAS accreditation, DLA approval, for MIL-STD 883 and MIL-STD 202 test methods is a good indication of how difficult it is to obtain them.

In addition to agencies like the UKAS and the DLA, we are also regularly audited by our customers. For us to be eligible to participate in certain space programs, a major US space agency's auditors join the DLA team to evaluate our test house. In fact, one agency auditor was so impressed by our operation he remarked that we had one of the best test houses he had ever audited. 

Q: Why would customers want to use our test house over their own house or one of our competitors?

A: Firstly, many companies that previously performed testing in-house have made the transition to outsourcing testing. It’s easier and more cost effective for them to utilize our test house rather than maintaining their own testing facility and equipment, gaining the necessary approvals and accreditations, etc. Outsourcing has become so attractive to our customers that we have seen our external testing double over the past few years. 

As for our competitors, we offer a unique suite of credentials that few other test houses can match. DLA approval is not common in the UK or Europe, and the requirements necessary to gain the approval are very stringent. The fact that we have obtained both DLA approval and MIL-STD 883 and MIL-STD 202 certification gives our customers excellent confidence in our capabilities. 

We also offer unique test methods to the UK and European markets: liquid to liquid thermal shock, high level constant acceleration, and high level mechanical shock up to 30,000g. A few years ago we upgraded our vibration testing equipment so that it can now take a static load of up to 500kg. This allows us to perform tests in many different stages of the supplier chain all the way up to full chassis testing.

A Q&A on API Technologies’ New RF/Microwave Engineering Online Design Tool with Molly Weis, RF/Microwave & Microelectronics (RF2M) Marketing Manager

by Jaymie Murray 15. October 2014 16:19

With the launch of API’s brand new RF/Microwave product configuration tool, engineers can now modify API’s standard RF/Microwave products to fit their individual requirements. The interactive tool allows for changes to existing designs, such as noise figure, frequency range, and power supply voltage and provides package style options.

Molly Weis, API’s RF/Microwave & Microelectronics (RF2M) Marketing Manager, has managed this project from the start, and has some insight as to what makes this tool so special.

Q: What was the motivation behind creating this tool?

A: Recently, API has begun offering more standard configurable products, such our new line of affordable surface mount synthesizers and we wanted to offer users an interactive tool that would allow them to explore all of our product capabilities. This tool puts the engineer in the driver’s seat, providing a way to design a product that fits user specifications with minimal effort.

Q: What are some of the tool’s benefits?

A: After the parameters are entered into the tool, it creates a printable, custom design summary based on the user’s specifications. The system supplies a permalink to the configuration, allowing the user to return to their design and make modifications as necessary. This link can then be easily shared among team members via email or social media, facilitating collaboration. 

Also, by having the engineer customize the product to their unique specifications up-front, we are able to shorten lead times and reduce costs. 

Q: Do you have any plans to expand the tool’s capabilities in the future?  

 A: Absolutely. As we continue to grow our configurable product offerings, the tool’s capabilities will be upgraded to include ways to modify those products to suit customer requirements. The beauty of this tool is that is extremely flexible and can be programmed to configure a multitude of variables.

6 Benefits of API Technologies' TPS75 Tactical Power Supply Solution

by Jaymie Murray 25. September 2014 11:58

Faced with growing demands from increasingly power-hungry, high tech devices, soldiers in the field often struggle to access the critical and reliable ower they need for these devices. API Technologies' TPS75, a 75 Amp commerical off-the-shelf (COTS) tactical power supply, provides these soldiers with the essential power and portability they need to satisfy mission requirements.

TPS75 Benefits:

  1. Supports the heavy power demands of applications such as RF and mobile networks and eliminates the need for tactical, vehicle-based power
  2. Allows vehicles to be deployed elsewhere while it distributes power to mission critical equipment from a generator or local shore/community power
  3. Decreases fuel consumption and wear and tear on vehicles by eliminating run time to support powering fielded special ops equipment
  4. By using generators with the TPS75, loud vehicles are not necessary for powering network equipment and can be turned off, allowing soldiers to work in a quieter, and at times, safer, environment. This also makes the TPS75 perfect for simulation and training environments
  5. Rugged design makes it the first of its kind to offer an integrated vehicle battery charger with an available roll cage and watertight construction, allowing it to function in harsh environments such as standing water, rain, and blowing sand
  6. Reduces the overall cost of ownership of military vehicles
