Can they produce custom PCBs according to your own design？
Size and shape play a major role in manufacturing PCBs. Traditionally, companies used to produce devices that were large in size, but recently, compact devices have been preferred.
If you also want to change the size of your device from the traditional devices and develop a compact one, you need a PCB supplier who can handle PCBs that easily fit a device smaller in size.
In aerospace or wearable sectors, you need a PCB that is smaller in size and also weighs less. Only a skilled supplier will be able to produce a PCB that is the perfect size and meets your performance requirements.
You would have already known that different PCBs have different layers. The number of layers depends on specifications and requirements.
If you develop traditional or relatively simple devices like radios and toys, you will need single-sided PCBs. However, if you manufacture advanced devices such as computers, laptops, or medical equipment, you will need multi-layer PCBs. With multi-layer PCBs, you will even have to customize the number of layers. Some devices require a PCB with 4 to 6 layers, while some devices require 18 to 30 layers and even more. Therefore, make sure that your PCB supplier can create a PCB with the required layers.
Can they provide custom PCB assembly?
To manufacture a PCB, you need different types of components. These components can be of various sizes. Similarly, manufacturing a PCB requires different types of technologies.
Some use surface mount technology, while others use through-hole technology. In surface mount technology, SMT components are mounted directly on the surface of PCBs, resulting in precise and more compact designs than those using through-hole mounting.
Additionally, each component has specific requirements that must be fulfilled. Your PCB manufacturer should design a PCB that meets the requirements of voltage, current, and power ratings.
Most importantly, temperature plays an integral role in maintaining the integrity of these components. Some components generate more energy and heat. Therefore, your PCB supplier needs to meet these requirements to ensure no short circuits and electrical loads.
Can they manage power requirements?
Different devices have different power requirements. Some demand higher power, while others require lower power. The power requirements determine the width and thickness of PCB traces.
Higher power necessitates broader and thicker traces to handle the increased current without overheating or cracking.
If the power requirements are not met properly, it can cause overheating. For example, if you develop laptops and computers, the PCB should handle higher power requirements. Hence, your PCB supplier should be able to handle the power requirements of your devices.
Do they consider environmental factors?
The location of your business and the environmental factors that affect your target market are crucial in PCB design and manufacturing. For instance, your company may be based in a totally different climate from that of your competitors, and this could affect the types of processes you have to implement as well as the materials that are best suited for you.
Most importantly, if warm and humid areas dominate your target market, this aspect should be crucial for your PCB design plan.
Moisture absorption is one of the problems that are observed in PCBs when they are operating under high-temperature and humid conditions. This, in turn, leads to corrosion and electrical short circuits. High temperatures can also cause stress on the PCB materials, leading to warping or delamination.
As such, it is important to select materials and design PCBs that can function in these conditions. These can be high-temperature laminates, moisture protection using conformal coatings, and thermal expansion design.
Besides, the manufacturing processes of your business can be affected by the local weather conditions. For example, the humidity and temperature control in a production facility may not be as difficult for a firm located in a more temperate and dry climate compared to one operating from a tropical region.
Therefore, your PCB supplier should be mindful of the environmental factors and customize the manufacturing process according to your location.
Can they customize the budget?
Budget is a big factor in determining your custom PCB supplier. Whoever you team up with should be able to customize the package according to your budget.
You can compare suppliers and then get quotations. Choose the best price you get that you can easily afford. Therefore, there are some additional tips for you that will help reduce your costs.
▶You can reduce the complexity of your PCB design by asking for fewer layers. ▶To manage your budget, you can skip advanced components and opt for simple and local ones as they are relatively cheap. ▶Select simple designs that are smaller in size. Larger and more complex designs can be expensive. ▶Place bulk orders because they are more economical and convenient than purchasing individual orders.
Can they meet the lead time of your custom PCB?
Quick lead time is another critical tip that you should consider when selecting a PCB supplier. Lead time varies from same day to weeks. For standard PCB production, the lead time for low-volume PCB assembly and manufacturing could be as quick as one day. As for custom PCB, the lead time differs from one PCB supplier to another concerning their PCB assembly and manufacturing capabilities. In this way, it is imperative for you to evaluate suppliers’ capabilities ahead of quotations. A qualified electronic contract manufacturing (ECM) partner can significantly improve PCB lead time.

PCB prototypes are the foundation of electronic product development, allowing engineers to test functionality, identify design flaws, and optimize performance before mass production. Choosing the right PCB prototype service is critical to ensure quality, control costs, and meet project deadlines. Whether you’re designing a consumer gadget or a high-performance medical device, understanding key factors can make or break your project. In this comprehensive guide, we outline the essential considerations for ordering a PCB prototype service, from material selection to emerging trends, to help you achieve a seamless prototyping process. Let’s dive into the core factors that will guide your decision-making.
The PCB material determines electrical performance, thermal management, and durability. Selecting the right material aligns your prototype with project requirements and budget.
Common materials include:
For most prototypes, FR-4 is sufficient due to its affordability and wide availability. However, advanced applications (e.g., 5G devices) may require Rogers for superior signal integrity.
Avoid choosing materials without consulting your manufacturer. For example, using Rogers for a low-frequency prototype unnecessarily increases costs.
Case Study: A drone manufacturer selected Polyimide for a flexible PCB prototype, enabling a compact design that reduced weight by 15% and improved flight efficiency.
The number of layers impacts design complexity, cost, and lead time. Single-layer PCBs are simple and cost-effective, while multilayer boards (up to 32+ layers) support high-density designs.
Prototypes often use fewer layers to speed up delivery. Copper, known for its high conductivity, is the primary conductive material.
Over-specifying layers increases costs and delays. Work with your manufacturer to optimize layer count. Explore PCB layer design tips.
PCB size and shape affect manufacturing feasibility and cost. Smaller, rectangular boards minimize material waste and reduce expenses.
Check your manufacturer’s maximum board size (e.g., 500mm x 500mm at JHY PCB). Design compact layouts using PCB software to optimize space. Avoid irregular shapes unless necessary, as they increase production costs.

Oversized or irregular designs lead to higher costs, especially in bulk production. Test compact designs in the prototype phase to save money later.
Pro Tip: Use panelization techniques to maximize board usage. See JHYPCB’s design guidelines.
PCB thickness, ranging from 0.1mm to 8mm, affects mechanical strength and compatibility with components. Standard prototype thickness is 1.6mm for FR-4.
Thicker boards (e.g., 2mm) support heavy components, while thinner boards (e.g., 0.8mm) suit compact devices. Discuss thickness with your manufacturer to ensure structural integrity.
Specifying non-standard thickness without justification increases costs. Verify requirements early.
Trace width and spacing determine PCB compactness and electrical performance. Narrower traces enable denser designs but require advanced manufacturing.
JHY PCB supports minimum trace width and spacing of 2.5 mils. Wider traces reduce costs for prototypes, while tighter spacing suits high-density boards.
Overly tight spacing increases manufacturing complexity and cost. Balance density with budget.
Vias (for interlayer connections) and drilling holes (for components) impact functionality and cost. Minimum hole sizes vary by manufacturer.
Mechanical drilling is standard, but laser drilling offers precision for microvias in HDI boards. Confirm your manufacturer’s capabilities to match your design.
Specifying overly small holes without advanced drilling technology delays production.
