Our team of experts is ready to work alongside your design engineers and turn the conceptual idea into a schematic design. We have FPGA Engineers who can develop the hardware design of a new FPGA by working closely with your software team to define and carry out the verification flow.

We are ready to support our customers with the schematic capture.

• We can work using netlist, schematic design file, PDF to be imported or converted into an ideal CAD design.
• We can do reverse engineering using an existing printed circuit board assembly (PCBA). Not only will we provide the Gerber file but also a clean bill of material (BOM).
• Our schematic design will be clean and easy to follow for the lab technicians, design engineers, or field technicians as needed.

PCB layout design is the essence of our proficiency in this industry. Whether it is the simplest 2 layers board or be it high-density interconnect (HDI), we have the expertise to meet our customer's needs. The layout design is the bridge to communicate the design database with the fab house in the form of a Gerber and or the intelligent data format of ODB++. The working functionality of the electronic design will mainly depend on the correctness of the schematic design, but it should also be noted that if the PCB layout is not done with the proper steps and rules, it is guaranteed to get a product that is either not functional at all or will be working intermittently. Using our wealth of knowledge in designing analog, digital, RF, and mixed-signal designs, we are sure that we will get it right the first time.

By working directly with our fab house partners in Shenzhen and Huizhou factories, we will be able to meet your PCB fabrication need for prototype and or mass production. Products that are used for various end-users including defense, industrial control, communication, medical instrument, commercial products, and automotive electronics are commonly fabricated at these two facilities. Quality is guaranteed with the best customer service to each customer. Both fab houses are certified by an international quality system such as ISO 9001:2008, US & Canada UL certificates E466113, TS 16949 & RoHS Compliance.

• Rigid PCB
• Flexible PCB
• Rigid-Flex-PCB

Just like the fab house, we have a close working relationship with the assembly house in Shenzhen, China who handles component procurement assembly and testing. They can handle both prototypes as well as low to medium-volume production runs. Their capability of assembling BGA, Micro-BGA, QFN, and fine pitch package IC’s with the highest quality has made them be the top service provider to high-end companies throughout the world. They also undertake any IC programming as needed. Functional testing (FCT) is part of their high-end service. By using automated optical inspection (AOI), they made sure that they provide a fast and accurate inspection.

Types of PCB Assembly

• Rigid PCBs
• Flexible PCBs
• Metal Core PCBs

The design of the PCB followed by the fabrication and assembly went superbly well and now you have a working board. But if your product is going to be used in a harsh or extreme environment then you will be obliged to safeguard it from damage and increase the reliability by applying conformal coating. There are circumstances also when the circuitry is used in an environment where gas is involved; a good example can be a gas flow meter or valve switch. So, in this condition, it is critical to apply conformal coatings and even potting to avoid the possibility of explosion.

What are the different types of PCB conformal coating?

1. Acrylic Resin (AR)
2. Silicone Resin (SR)
3. Urethane Resin (UR)
4. Epoxy Resin (ER)

One of our core rationales for starting ADDIS PCB Design LLC is to create awareness to the bright and innovative young Africans that they can and must play their part to make Africa be part of the global Printed Circuit Board (PCB) industry. It is projected that the global PCB market size to reach $86,170 Million USD by 2026. The continent of Africa does not have any part in the projected market size of any kind other than being a consumer with a population of 1.216 Billion.

When we think of PCB, the first thing that comes to our mind is the fabrication process of the PCB. That being the core of the process, the initial development starts with the PCB layout design. Without the artwork (Gerber files) generated by the PCB layout designer, it will not be viable to manufacture the PCB. Therefore, the groundwork of the process is the PCB layout design.

PCB layout design can and should be mastered by as many African young students and should be encouraged by every institute throughout the continent. PCB layout design is a very exciting and worthwhile job that can be learned by all Electrical Engineering students and or any technical school attendees. All the major electronic design automation (EDA) tools can be made available for any university and college for free. There are a number of EDA software’s that are available these days to learn and be able to know how to design PCB layout.

Once the artwork (Gerber) is finalized, the ensuing phase of the course is the fabrication advancement. This is the step to transform the artwork into a physical shape. The fabrication part of the PCB design process is by far the one that may be a bit challenging as it is a technique that involves various steps such as

1. Copper-clad lamination.
2. Etching of copper from the layers.
3. Putting together (laminating) by heating and pressing the etched two-sided copers to create the board stack up.
4. Drilling holes and vias.
5. Plating holes and via holes.
6. Putting solder mask.
7. Reference designator, logos, and any other identification will be printed on the silkscreen.

It is very clear that China has become the stronghold of electronics manufacturing. The baby steps that China has been taking more than 20 years ago has now made it to be the powerhouse of the electronics industry. It did not blossom overnight but it took its own course of hard work and commitment to get the major part of the PCB output of the world.

Africa should learn from China and start to take those small steps. Apply the popular Chines proverb "The best time to plant a tree was 20 years ago. The second best time is now"

Addis PCB Design has been trying to communicate and even collaborate with institutes and organizations in Ethiopia to implement ways to take the small steps. Addis Abeba Science and Technology University AASTU), as well as Ethiopian Toll Roads Enterprise (ETRE), are two of the institution and organizations that ADDIS PCB proposed ways to start and apply the small steps using technology transfer.

Currently, Addis PCB Design is working closely with local sister company ADDIS Tech Group to start PCB Assembly for prototype boards.

Addis PCB Design will be designing reference designs based on open-source designs such as the Arduino board as well as designing products that are suitable for the African market. Addis PCB Design will be working with a company based in Ethiopia called ADDIS Tech Group to come up with products that are suitable for the Ethiopian market. There are some products that are lined up to be started in Addis Abeba. Knowledge transfer is one of the goals of Addis PCB Design which will also create job opportunities for the local people.

Addis PCB Design can work closely with various sectors depending on their need. Nowadays with the increase of using - smartphone, smart home, smart switch... SmartThings, there are quite a lot of projects that Addis PCB Design can provide to the various consumers and various sectors.
