Let's explore these areas as part of a guide to ensure you get the products and services you need. But first, let's start with the basics...
Who Needs PCBs?
PCBs have a wide range of applications, typically involving electronics engineers, product designers, or electronics buyers, production managers, and engineers from industrial, commercial, or even military backgrounds.
What is a PCB?
A Printed Circuit Board (PCB) is a substrate on which electronic components and highly conductive tracks are soldered to form a circuit. When arranged in a specific layout, it contains particular components that perform simple or complex electronic tasks, the simplest being a basic switch.
Know the Type of PCB Assembly You Need
There are numerous types of PCBs, and if you want to get the product you need at the end of the process, it's crucial to provide as much information as possible about the PCB’s final use, as well as detailed specifications.
With this in mind, ensure that you have a thorough overview of the product's purpose. What is its function? Ultimately, you need the PCB to accurately fulfill that product's requirements.
Mistakes at this stage can have long-term impacts on the product and project. Therefore, getting this stage right from the start is critical to prevent misconfigurations later on.
An experienced manufacturer should be able to help you avoid these pitfalls by bringing their expertise to your project. So, be sure to utilize their knowledge, and help them understand your needs.

For those already familiar with PCBs, let's discuss the qualities to consider when choosing a PCB manufacturer and assembler.
Experienced PCB Manufacturers
There are many PCB manufacturers that specialize in specific industries, so it's important to find one that can meet the type of product you're looking for.
Building a relationship with your PCB supplier is a good idea, as they will be more willing to offer their expertise to guide you regarding your needs, in a cost-effective manner. They will care about your product, your satisfaction, and ensuring your future business.
Choose a Single-Source PCB Solution
Whenever possible, find a manufacturer that can meet not only your immediate product needs but also the range of products you might require in the long term.
For example, at RayPCB.com, we offer a wide array of PCB types, covering almost the entire range of options. Here's a list to help you understand the types you might need now or in the future:
The rapid growth in demand for multilayer boards is due to their advantages over double-sided boards. They are ideal for more dense circuits and product miniaturization.
- Rogers PCB
Rogers PCBs are often used by military and consumer units, typically consisting of 3 layers and surface mount technology to ensure stability.
- LED PCB
LED boards offer a variety of solutions, from simple outdoor LED screens to complex high-power LED lighting systems.
- HDI PCB
HDI Microvia PCBs are a rapidly developing technology. They typically have a higher circuit density than traditional PCBs, with six main types available to meet various tasks.
- Express PCB
Popular among hobbyists and engineers worldwide, these can come in various types and are often turned around in about 24 hours, depending on your needs.
- Aluminum PCB
Commonly used for applications requiring high heat dissipation, aluminum boards are ideal for high-power and tight-tolerance applications.
Widely used in aerospace and military applications, rigid-flex PCBs are highly reliable. They are rigid in areas where front-end support is needed and flexible in areas that involve corners and/or moving applications.
Other Important PCB Manufacturer Services
There are additional services you can receive from your PCB partner. These types of services demonstrate their knowledge and attention to detail, their commitment to making your project work for you, and quick, "off-the-shelf" solutions designed to meet your needs. For some examples, here are a few of our additional services:
- Prototype PCB Assembly
A great manufacturer should be able to handle complex designs with qualified staff and flexible production facilities to build and test them.
- PCB Assembly Services
Your manufacturer should have a broader understanding of printed circuit board design and be able to effectively understand your final product. These services should include:
- Quick-Turn Prototype Assembly
- Turnkey Assembly
- Partial Turnkey Assembly
- Consignment Assembly
- RoHS-Compliant Lead-Free Assembly
- Non-RoHS Assembly
- Conformal Coating
- Final Box Build and Packaging
- Turnkey PCB Assembly
Partial or full assembly might be important to you, so be sure to inquire in this area. An experienced manufacturer should be able to handle the entire process on your behalf.
Manufacturers can vary greatly in cost-effectiveness, reliability of product delivery, board types (single-layer, double-layer, or multi-layer), and the level of after-sales service you receive.
We recommend discussing with the manufacturer their experience in handling your specific type of custom assembly.
Sourcing Original PCB Components
Some PCB manufacturers are merely assembly lines and may attempt to cut corners by using lower-quality third-party components to save costs during their assembly process. We are proud to say that we use only the highest quality components, and due to our scale, we can ensure the prices are as low as possible, passing any cost savings onto our clients.
The guideline here is – if you intend to work with a manufacturer, make sure you have clear answers on where they source their components. Are they original components as well?
Quality of PCB Products
Cost often (but not always) determines the level of quality. The trade-off, of course, is the budget available for the product costing, but also the potential hassle of returning large batches of low-quality products because you chose a manufacturer who offered low-quality products at a low price.
Consider understanding the quality control methods used by the manufacturer. What is the threshold for defective products versus fully functional products? Most of this will be monitored through ISO certification standards (see certifications below).
Additionally, what is the return procedure and other service levels included in the price? What you really need is reliability in both products and services. This leads us to industry standard certifications...
Industry Standard Certifications
At a minimum, you should ensure that your PCB boards will be manufactured according to some basic industry guidelines that cover aspects such as safety and workflow. Here’s a guide to the certifications your PCB manufacturer should hold:
- ISO (International Organization for Standardization)
Ensures your products and services conform to international standards that meet customer expectations.
- IFA (International Certification Forum)
World association for system, product, service, and personnel compliance.
- UL RJ
Relates to proper legal product labeling and safety guidelines and specifications.
Manufacturing Costs
Shopping around to get a good overview of pricing is key. Price isn’t always the determining factor, but it’s hard to achieve low cost and high quality simultaneously.
Many larger and more experienced PCB manufacturers will have higher prices, often due to covering larger overheads. Similarly, some smaller operators will set low prices to enter the market and fulfill orders – but consider the level of service they offer.
This is a tricky area, so by shopping around, gathering information about each of your options, and researching, you can better understand where to go and what to expect. Matching your budget is important, so make sure the product fits within your budget, and then weigh other factors to get an understanding of who you are dealing with.
Production Speed
This area can vary greatly, and you need to ensure your PCBs arrive when needed. Sometimes you may need them quickly. The standard turnaround time for most industry-standard PCB boards is about five days, so this can provide you with a working guide.
Conclusion
Choosing the right PCB assembly manufacturer is a strategic decision that can significantly impact your project’s success. By understanding your needs, evaluating the experience and services of potential manufacturers, and considering factors like quality control and communication, you can make an informed choice.
