For the small volume PCB assembly process, we use three different technologies –

1.Through-hole Mounting

While we opt for this method for low volume PCB assembly, our designers place the requisite components in the holes drilled on the board. Although an old-school technology, we make the best use of this technique. Especially for industrial applications in aerospace, we make use of this technique to make your circuit boards withstand high levels of stress and operate at high speeds and temperatures. We make sure the bond between the circuit and its components is stronger and hence you can have a reliable product that provides a high level of efficiency for your operations.

2.Surface Mount Technology

Our purpose to go for the SMT technique is to improve the quality as well as performance. As we mount the components onto the surface of PCBs, we offer tremendous flexibility, and more importantly, even the complex circuits can be done into small assemblies. Even the smallest of the components can be mounted by using contact terminals instead of leads. Also, we meticulously build dual-sided circuit boards with all the components on one side and complex circuitry on the other side. Through the automation process, we build highly customizable circuit boards for almost any application.

3.Mixed Technology

We use the properties of SMT and through-hole whenever necessary. We are a reliable small batch PCB manufacturer and well-equipped with the capabilities of both SMT and THT for manufacturing circuit boards. We can provide quick prototypes and even go for high-speed production. We have advanced and precise equipment to place the component of miniature size with great accuracy. You can have custom assemblies that are built by following the best practices in the industry.

Some Suggestions about Low Volume PCB Assembly

In low-volume PCB assembly, following some rules may make your production less troublesome, here are some suggestions：

Reducing the number of layers

Minimizing the number of PCB layers is a critical cost-saving technique in assembly. By reducing the layer count, you can lower the overall material and component expenses.

Appropriate Sizing

You need to exercise utmost caution when determining the size and planning critical aspects like annular rings and holes. Precision and accuracy must be maintained at all times.

Avoid Internal Cutouts

Eliminate internal cutouts in the printed circuit board to reduce costs associated with fixing them. This will result in savings on material costs for internal routing and through-hole drilling.

Selecting the most suitable vias

Selecting the optimal vias that seamlessly integrate into the PCB assembly process is of utmost significance. While these vias might come at a higher initial cost, the long-term benefits will result in substantial cost savings and smoother production.

Stick to Basic Options

Sticking to the basics ensures smooth assembly processes and avoids unnecessary complexities.

Low Volume Assembly and Testing Processes

Assembly and testing are crucial to ensuring Military PCB reliability. At PCBAndAssembly, we perform surface mount technology (SMT) and through-hole assembly using IPC Class 3 standards. Our inspection and testing processes include AOI, X-ray inspection, in-circuit testing (ICT), and functional testing. We also offer flying probe and environmental stress screening (ESS) to simulate real-world operating conditions. These steps ensure each Military PCB meets stringent quality and performance benchmarks.

Low Volume Assembly FAQs

What is low volume PCB assembly?

Low volume or a small batch PCB Assembly is the process of mounting components to the small batch of boards. The number of boards can be in the range of 25 to 5000. Due to small batches, this is called a low volume PCB assembly. There are times when you need PCBs for your application but you don’t need a large batch. Like the regular PCB Assembly, even the low volume PCB assembly process also involves 3 steps – PCB fabrication, component mounting, and assembly.

What are the benefits of small batch Printed Circuit Board Assembly?

A low volume PCB assembly is usually defined as small amounts of less than 5000 PCBs. It is ideal for building new products, repairs/replacements in the final product. If you have time and cost limitations while you need a PCB for your application then you need to go for low volume PCB assembly as it reduces your cost, time and offers optimal quality circuit boards.

What is the cost involved in small batch PCB assembly?

Depends on the number of boards you want us to assemble. But we look for ways to improve your cost savings wherever possible. We strive to maintain long-term relationships with our clients and suppliers and hence purchase quality parts at competitive prices. We ensure that our customers obtain the highest quality that any PCB turnkey service provider can provide.
