Catching up With Darrel Yarbrough of YES


Reading time ( words)

Yarbrough Electronic Sales (YES) is one of the fastest growing contract manufacturers in the Southwest. As people get to know them better, they are becoming the go-to company in their area. They have already developed a customer base that spans both coasts of the United States. I had a chance to visit their pristine facility in Tucson a few weeks ago, and I was fortunate enough to sit with Darrel Yarbrough, owner and long-time industry veteran. Here is his story.

Dan Beaulieu: Darrel, it’s good to see you. When did you start Yarbrough Electronics Sales (YES)?

Darrel Yarbrough: My pleasure. I started YES as a manufacturers sales group in October of 1987. After 10–12 years, it changed to a contract manufacturing operation.

Beaulieu: So, you were a sales rep before you started this company?

Yarbrough: That’s right. Initially, I represented a local PCB manufacturer and a large sheet metal fabricator in Phoenix. As my customer base grew, I added some more principals, such as machined parts, stamping, screw machine parts, and injection molded plastics. As the list of principals grew, I expanded the territory and hired my sister in Albuquerque, New Mexico.

Beaulieu: You were all in as a sales company. What was your plan and vision at the time?

Yarbrough: The vision was to grow the business enough to be able to support my parents comfortably. My father was a WWII veteran who couldn’t do construction after injuring his back several times. But, as you well know, the jeopardy of being a sales representative is if you start making too much money in the eyes of the principal, or the principal’s new son-in-law needs work, you are replaced overnight. After that happened a few times, I decided that enough was enough and that I would be better off being an owner of a company rather than being beholden to the owner of a company I represent. That’s when I started my own manufacturing company. I had 15 years of contacts with many types of manufacturing requirements and had developed many friends in the business community. I also leveraged the tribal knowledge from my customer base and their experiences to help me during the transition to manufacturing. I felt that I was poised to start my own business in October of 2000.

Beaulieu: That’s a great story. What makes YES a standout among contract manufacturers?

Yarbrough: We are a full turnkey contract manufacturer for electronics specializing in high-technology assemblies for engineering development—prototypes through production orders. We have a reputation for quality, high-reliability, flexible, and cost-effective solutions for our customers. We are very proud of our record for over 20 years of building special products for the department of defense contractors.

Beaulieu: You also work with DoD customers, which is pretty impressive.

Yarbrough: Correct. That came from some of the contacts I had made when I was in the sales business. The next segment of our business is relegated to the medical industry. We have three companies who are operators in solutions for biventricular heart failure. Their products range from left ventricular assisting devices (LVADs) to a total artificial heart replacement. We do not manufacture any implantable devices. The specific products we build are related to the controllers and wearable battery pockets. The remaining 25% is business with small industrial applications and heavy mining equipment. Tucson is the world headquarters for several large mining companies. These products are designed for durability and reliability for use in diverse operating conditions.

Beaulieu: Next, can you talk about your assembly capabilities?

Yarbrough: Currently, we have two surface-mount assembly lines. One is set up for quickturn capability and small quantity runs. The other line has the capability for conveyor operation, higher quantities, and longer run times between jobs. The two lines are identical as far as software, hardware, and capabilities, so we can interchange jobs at any time if needed.

Beaulieu: What are your specific capabilities?

Yarbrough: Each line consists of DEC screen printers, MyData12E pick-and-place machines, and Vitronics reflow ovens designed for RoHS solder. Some of our specific capabilities include bare board assembly. In addition to SMT assembly, we have several assemblers trained to do hand soldering of SMT components, connectors, power modules, and wires. We also do box builds. Currently, I am in the process of adding a work cell for box build jobs, including adding cables, assembling sheet metal, and testing with manual meters and probes. We have some customer-supplied, PC-based test equipment, which is used in final inspection too.

Then, we do turnkey and have a stockroom for components with approximately $1 million in inventory that we manage. I have a senior buyer, two people in the stockroom, and another person for customer support with over 30 years of purchasing experience. Finally, we have special services, including acrylic conformal coating, application of RTV, and other types of gluing parts to the board. We can also install cables, torque components, and assemble plastics if needed.

Beaulieu: Let’s talk some more about technology for the future and how it is needed. Where do you see technology going?

Yarbrough: Designers are always going to more layer counts, smaller components, and higher density to maximize the real estate on the boards. We see multiple BGAs, blind and buried vias, epoxy-filled vias, and controlled impedance requirements becoming more common.

Beaulieu: Where do you rate YES in terms of technology?

Yarbrough: In terms of hardware, I would say we are a solid eight. We don’t have the latest high-volume production machines, but the equipment we have is perfect for the scope of our work. We have the accuracy and flexibility to be competitive.

Practical Implementation of Assembly Processes for Low Melting Point Solder Pastes (Part 1)

07/16/2019 | Adam Murling, Miloš Lazić, and Don Wood, Indium Corporation; and Martin Anselm, Rochester Institute of Technology
Since 2006 and the implementation of the RoHS directive, the interest in bismuth-tin solder alloys—whose melting point around 140°C is very desirable because it allows for the use of lower temperature laminate materials and reduces thermal stress on sensitive components—has only increased as the industry has searched for Pb-free alternatives to the chosen standard, SAC305, which melts at considerably higher temperatures than the incumbent tin-lead alloys.

Surface Treatment Enabling Low-Temperature Soldering to Aluminum

07/15/2019 | Divyakant Kadiwala, Averatek Corporation
An increasingly popular method to meet the need for lower cost circuitry is the use of aluminum on polyester (Al-PET) substrates. This material is gaining popularity and has found wide use in RFID tags, low-cost LED lighting, and other single-layer circuits. However, both aluminum and PET have their own constraints and require special processing to make finished circuits.

Failures and Reliability in Soldering

07/09/2019 | Michael Gouldsmith and Zen Lee, Thermaltronics
The definition of failure is "the lack of success in doing or achieving something, especially in relation to a particular activity." If the activity is concerning a soldering process, such a failure can have a downstream impact far beyond the actual solder joint. In this regard, it is first necessary to understand what constitutes a good solder joint because appearance is too often deemed a success.
