EMS PCB By Types
EMS Prototype PCB is an inexpensive and flexible solution for product design. EMS PCB allows you to quickly replace mechanical parts and make it easy to get started on product development.
Designed to turn around your PCB as soon as possible, depending on your board features. This is ideal if you need to catch up with a short lead time or due date and can’t afford to wait for full-turn service.
EMS Low-Volume Production of printed circuit boards is an affordable, turnkey solution for low-volume production and prototype manufacturing. With the ability to produce small quantities with fast turnarounds.
With the help of high-speed laser machine and multiple components placement head, the production processes become more efficient when making high volume custom design EMS PCBs.
The HDI EMS printed circuit board is a high density interconnect (HDI) technology offering high performance, reliability, and cost-effectiveness by integrating the system board with the electronic components.
A compound printed circuit board, which is designed and manufactured to meet high frequency operation requirements. Commonly used in manufacturing high-speed radar and transceivers.
EMS PCB Introduction
Companies that create, produce, test, distribute, and offer return/repair services for electronic components and assemblies for original equipment manufacturers are known as electronics manufacturing services (EMS) companies.
EMS providers might be small, one-person operations or global, multi-location corporations. Usually, they are in charge of everything, including original design, tooling, product assembly, and packaging of printed circuit boards. The term “electronics contract manufacturing” also refers to the idea of offering EMS on a turnkey basis.
Design and Testing Services
Electronic design and testing is a very complicated process, and if you are not familiar with it, it can be hard to know where to start. If you do have the capital to carry out such activities, you may want to consider outsourcing some of the design activities to an Electronic manufacturing services (EMS) company like PCBTok.
PCBTok’s EMS PCB companies have in-house teams that can support the design and testing of any type of electronic product. As the Electronic Manufacturing Services (EMS) company, we have manufacturing capabilities it would be wise to keep things under the same roof and outsource the entire project here at PCBTok.

EMS PCB Fabrication
An OEM is a company that sells parts, components and even finished products to other companies. An OEM doesn’t make products itself; instead, it purchases them from third-party suppliers. In addition, an OEM doesn’t just sell these items for its own use; it also sells them to its customers.
In contrast, an EMS is an electronics manufacturing service provider that specializes in the production of electronic equipment. It typically provides contract manufacturing services to other companies. The main difference between an EMS and an OEM is that an EMS doesn’t sell any of its products directly to consumers or businesses.
Both SMT and THT Technology is available for EMS PCB. It is important to note that although these two technologies are different, they have different processes and requirements.
Through-Hole technology involves inserting components with tails or leads into holes drilled in the PCB. These components will be described as through hole components.
Surface Mount Technology is a method that is used to assemble electronic circuits, where the components are mounted or placed directly onto the top surface of printed circuit boards.
OEM & ODM EMS PCB Applications
The EMS printed circuit board for telecommunications is designed to ensure a high-quality, reliable connection between your equipment and the rest of your telecommunications system.
EMS PCB are an essential to any product that uses a radio frequency. RF circuits vary in complexity from simple to complex. Can be used to build a single-chip transceiver or multi-chip transceiver.
EMS PCB for aircraft instrumentation is a high-quality, low-cost solution for your product needs. We take pride in our ability to deliver high-quality products on time, and we can help you do the same.
The EMS PCB designed for CD players. The PCB has been designed with high-quality materials and components. Made using the advanced technology, which makes it durable and reliable.
EMS PCB which is designed for Remote Control Toys, is a high quality, reliable, and cost-effective circuit board that can be used in a variety of applications especially for remote control toys.

I would recommend PCBTok to my friends, family and everybody else.”Beverley Alli, Systems Engineer from Lincolnshire, England
“PCBTok is a reliable supplier for the electronic circuit boards. I have ordered from them many times and the quality of their products are good. The price is also affordable. The customer service is very responsive, and they always send you samples before you place your order. In addition, they will also provide you with free shipping when you place your order in bulk amount. Their delivery time is also fast and most of all, they’re so much cheaper than other suppliers that offer the same products with better quality.”Efren Saldivar, Electronics Technician from Brownsville, Texas, U.S.
“The customer support at PCBTok is excellent! A handful of my PCBs required a different finish, and they quickly altered it for me. The only business I could locate that offered free delivery was PCBTok, and you guys more than lived up to my expectations! My boards arrived in fantastic shape, and shipping only took approximately 3 days. When I required assistance with some design issues, the man who answered the phone was quite helpful, and overall PCBTok is a terrific site to get PCBs!”Russell Maurice Johnson, Computer Hardware Engineer from Ontario, Canada
