Customers seeking world-class embedded solutions often require custom-designed printed circuit boards (PCBs) for non-standard applications. The choice of supplier makes all the difference. An unbalanced design, a lack of in-house testing and prototyping, or uncoordinated production can lead to fatal flaws in the board design, ultimately at the customer's expense. A poor final design results in excessive costs, reduced performance, and increased risk of short circuits or other latent failures, especially in long-term applications. This can result in expensive redesigns or even product recalls.
SECO specializes in custom and standard solutions for x86, Arm, and FPGA platforms, focusing on deep customization to maximize value, lower costs, and speed up market entry. Overseeing every project stage, from design to testing, we ensure alignment with each product's unique requirements. Our durable, versatile products are designed for manufacturing and testing efficiency, which maximizes product yields and on-time delivery. SECO's broad range of technical offerings, including energy-efficient and high-performance solutions, is supported by direct, localized technical guidance for swift and effective market launches.
Reason 1: PCB Development is Completely In-House
There is a misconception in the industry that essential processes in a chain should be outsourced to specialized third-party companies in the hope of securing expertise in each step. The problem with this approach is that it increases costs and development time, making the flow of information considerably more difficult.
SECO began operating the entire PCB design process chain in-house at an early stage. Throughout the entire process, from stackup design to final production, no step is outsourced to external providers. We only externalize the fabrication of the unassembled printed circuit boards.
The advantages are clear: complete control over the PCB design and extremely short development times, with processes such as validation and testing all performed in-house. This significantly reduces waiting times and keeps information paths very short.
Reason 2: Our Approach to Circuit Board Design
The typical and most common approach to PCB design is as follows: PCB layout, build a prototype, test the prototype, identify errors at great expense. Once the bugs are fixed, the changes are incorporated into the redesign, starting a second design cycle where the steps are repeated. This can often result in 3-5 design cycles with an average turnaround time of 3-6 months. SECO executes this workflow differently: We typically require only 2 design cycles (a third depending on complexity) before a new product is ready for mass production. This reduces the project time by up to 12 months.
Marginally extending the initial design phase constitutes the cornerstone of our approach, necessitating only two, or at most three, development cycles. The rationale underpinning the efficacy of a limited number of design cycles is elucidated in points three through six.
After just 30-60 days, customers can expect a prototype for testing, with production often achieved within 100 days. The streamlined process also reduces redesign cycles, which can be as long as 3-6 months each.
Reason 3: PCB Stackup Library
Delivering a flawless PCB design in such a short time requires significant advantages, starting with the printed circuit board stack-up definition. While many companies start from scratch with every project, as does SECO, we have a considerable pool of proven designs at our disposal.
Established in 2013, SECO maintains a comprehensive stackup layer database containing a large number of tested designs. All of these designs have been extensively verified and are ready for immediate use. The database therefore covers many performance requirements and certain industry-specific specifications. Leveraging the stackup library enables us to often deliver a first design to the customer in 30-40 days, where the industry average is about twice as long - not including physical prototyping and industry average testing! SECO has reduced these steps thanks to simulations.
This database is constantly growing and new stackups are being added. New stack-up designs undergo a multi-stage validation process that includes simulations. SECO's design rules form the basis for validation and verification. Any of these numerous designs can be used immediately!
Reason 4: PCB Simulation
In addition to a unique database during the stackup, we are also able to bypass physical prototype testing in the early design cycles.
During the design phase, we run signal integrity and power integrity simulations directly within the design, eliminating errors early in the project. As a result, the initial design phase is slightly longer than those of others in the market.
In this way, we significantly reduce design errors at the outset, thereby minimizing time-consuming debugging and redesign phases later. Simulations are practical only if they are based on reliable fundamentals. Our simulation toolset includes software by the market leaders:
SECO’s design rules serve as the foundation for simulations and stackup definitions, enabling a streamlined process with a maximum of two to three design phases. (see Reason 5: Design Rules)!
Simulations include stress tests for all components, circuit nodes, and PCB stackup layers. This directly minimizes the risk of avoidable errors. Rigorous simulation of an antenna, for example, can significantly shorten redesign phases. Influencing factors, such as materials, position, and type, are simulated to achieve optimal performance.
By using simulation alone, we can save up to 2 redesign cycles for new developments and often implement the "one kill shot" principle. This results in a first physical prototype that meets 99% of the requirements.
Reason 5: Ruleset for PCB Design and Stackup Verification
Being able to control the entire chain, including comprehensive testing, and intervene immediately saves the customer considerable time and money, as the product has been thoroughly tested by us, encompassing every connection and component (including electromagnetic compliance, or EMC, tests).
The design rules are created based on a precise evaluation of each component and the most optimal connections, as well as the potential influence on other elements. The result is a comprehensive set of rules for building components and layer levels.
We spend significant time analysing components and interconnects in the stackup, so we know which elements work best where on the circuit board!
Reason 6: Prototype Verification and Validation
Subcontracting the testing of prototypes is common practice in the industry, but not at SECO. We test our prototypes within our co-located engineering and production sites. Verification testing encompasses a range of standards, from industry-compliant certifications (such as CE and FCC) to temperature cycling and testing in harsh environments. Where other companies may have a few people dedicated to testing, SECO has over 20 people primarily devoted to testing, validating and verifying circuit board prototypes.
Our range of tests includes vector network analysis (VNA) for signal integrity performance, EMC (emissions and immunity), climatic chamber testing, power measurement, and safety instrumentation. Additionally, we conduct detailed test planning, tracking, and report archiving. This all contributes to the continuous improvement of our circuit board designs and significantly improves our simulations.
