But their team has over 20 years of experience. They were part of the big growth of the China PCB manufacturer market. They know what it takes to build a great company. They worked with top companies like Huawei. This shows their experience is real. Mars-PCB lives by a simple idea. It is the “four highs” service concept: high reliability, high technology, high quality, and high efficiency.

Their core strength is their complete service. They can be your single partner. They do PCB Design & Layout services. They can take your idea and turn it into a blueprint. Then they start the pcb fabrication. They can make a lot of different types of boards. They make standard rigid boards. They also make complex boards like HDI and rigid-flex. They even work with special materials like Rogers PCB and ceramic. After the board is made, they handle the PCB Assembly. This is a big help for me. They do the whole pcb assembly process. This includes getting all the parts. They have a big network for component sourcing. They can do smt pcb assembly. Their lines can place millions of components every day. They are ready for both small prototype runs and big production orders. They even do box build services. This means they put the electronics in the final case.

Their technical skills are very advanced. They can make very fine lines. Their boards can have a 2/2mil line width. This is very small. It is for high-density applications. They can also make very thick boards. They can go up to 60 layers. They use modern via technologies. This includes micro-vias, blind vias, and buried vias. This is for complex designs. They use advanced materials for heat management. They have a professional team. This team has a lot of experience. They use modern machines. They make sure their products are high quality.

Quality is their main focus. They have a serious testing process. They test every board. They do flying probe tests. They do impedance tests. They test for solderability. They do thermal shock tests. A quote from Greg Engineer says it best: “PCB quality is the foundation for everything else that happens in the PCB assembly process.” They have a quality management system. This ensures every order is perfect. They pack the boards safely. They use custom packaging. This protects the boards during shipping.

Their customer service is very good. They are fast. I remember Mark G. Engineer’s words. He said, “Prior to contacting you, we reached out to many other PCB Manufacturers and could not find anybody to do a 1 day turn on this size board. We were really in a time crunch and Mars came through for us!” This shows their dedication. They have a lot of experience in many fields. This includes car parts, medical devices, and telecom. They work with customers in over 80 countries. They have a strong project management team. They remove a lot of headaches for you.

In the end, choosing a pcb board assembly manufacturing partner is a big decision. You can find great companies in Germany. But you can also find amazing partners in other parts of the world. Mars-PCB is one of the best. They have the technology. They have the quality. They have the experience. They can be your partner from the start to the end of your project.
