Printed Circuit Boards Assembly Services

If you’re looking for PCBs Assembly Services, this article is for you. It covers the cost of PCB assembly services, what you can expect from testing options, and the time it takes to produce a PCB. It also addresses the common problems associated with PCB assembly services. Finally, we’ll help you decide which option is best for you.

Problems with PCB assembly

Several problems occur during PCB assembly services. Many of these problems occur due to improper copper plating, which prevents electrical current from passing between the layers of the PCB. In addition, drilled holes in the PCBs must be clean to avoid contamination and air bubbles.

The quality of PCB assembly services quality depends on the PCBs’ design and PCB manufacturing. Therefore, a good PCB CM should validate the BOM before PCB manufacturing. It should also provide up-to-date DFM and DFT rules. A PCB assembly service that follows these rules will reduce the chances of problems during PCB assembly.

Despite being very detailed, PCBs are susceptible to chemical leakage. Even if manufacturers carefully clean their circuit boards properly, tiny amounts of chemical residue can remain on the board. Over time, these chemicals can corrode metal components on the board and cause short circuits.

PCB Assembly Surface Mount Technology

SMT is a process for attaching electronic components to a printed circuit board. The process is more complex than traditional assembly, requiring appropriate processes and equipment. Speedboard offers four fully integrated surface mount lines, including a DEK printer, three Siemens SiPlace component placers, and a five or seven-zone Omniflow oven. Conveyors and un-loaders link the lines.

Surface mount technology is not a substitute for a traditional PCB assembly process. However, it allows for more accurate finishes. Solder paste printing is a helpful method of preparing a board for SMT assembly, providing a clear guideline for components to be attached to the board. After the components are applied, a technician checks the complete circuit to ensure accuracy.

Before PCB Assembly SMT, almost all electronics were made using individual components. The process required the laborious assembly of thousands of diodes. Eventually, this process paved the way for the space race, which led to the development of the first computer chips and the “through-hole” circuit board design. In the late 1960s, the first integrated circuits came into operation. They encapsulated the advanced circuits in a black plastic housing. Long metal legs then connected them. These legs are the most significant physical characteristics of a through-hole PCB Assembly.

The PCB substrate is usually laminate, composite epoxy, or fiberglass. The conducting material used on the PCB is typically copper. It is also coated with tin-lead to prevent oxidation. The PCBs also have contact fingers on their outer edges.

Costs of PCB assembly services

Depending on the area of the world you’re in, the costs of PCB assembly services can vary wildly. In North America, labor costs are about three to four times higher than in Asia. Although many companies produce lower-quality PCB assemblies, their quality remains intact. In Asia, labor costs have increased dramatically over the past decade.

The size of the PCB, the number of layers, and the project’s complexity all contribute to the cost. The more complex the design, the higher the cost. In addition, the design has to conform to specific standards. This means that the contract manufacturer has to invest in long-term certifications.

The type of technology used can also affect the cost of PCB assembly services. For example, surface-mount technology is less expensive than through-hole technology. Surface-mount technology is more efficient and allows for a higher density of components on each board. However, through-hole technology requires additional drilling on the board and reduces routing space.

Testing options for the electronics industry

There are several different types of testing options for PCBs. For instance, burn-in testing will force maximum power through an electronic device for 48 to 168 hours. While this type of testing is not ideal for every project, it will ensure that your product doesn’t have premature failures. In addition, it will prevent you from launching a product that may be deemed dangerous or embarrassing

We perform functional testing by checking the functionality of a PCB assembly. This test will determine if the PCB will function as designed. Functional testing is best for large runs but not for small runs. It also ensures quality and longevity. The functional tests a PCB undergoes will depend on the end-use and the device used.

Another type of testing is in-circuit testing. In-circuit testing involves putting pressure on the connection with a special fixture. The fixture typically has a series of test probes. We can place the probes on the copper traces or the bottom layer PCB.

PCB Manufacturer Testing

The testing process at a PCB assembly manufacturer does not end with the prototype design. Once the boards are ready, the design team should test them once again to ensure the quality and throughput of the final product. Many different methods can help to ensure this. For example, automated measurements and X-ray inspection are two ways to inspect the boards to check for defects. In addition, these techniques can help test internal and surface layers and check for BGA or QFN packages.

X-ray inspection

We can enhance PCB manufacturer testing by using X-ray inspection. The high-energy radiation from X-ray inspection can penetrate the board’s components and detect hidden defects. X-rays are absorbed differently by different materials based on their density. Thicker materials absorb more X-rays than lighter ones. As a result, heavy-weight PCBs appear darker in images.

X-ray inspection can also help ensure high-quality products. For example, it allows manufacturers to inspect boards at all stages of the assembly process. Because it can be beneficial for pre-in and post-production, this process can save money by ensuring that only good-quality materials are essential in the production process.

It can also identify components that are missing or misaligned. For example, we can identify a circuit board that lacks adequate pin-hole fill by X-ray inspection.

Micro-sectioning analysis

The micro-sectioning analysis is an essential step in PCB assembly manufacturer testing. The process allows manufacturers to check the board thickness of copper plating, lead-free HAL, and other components. This process can reveal any defects or flaws, as well as the quality of overall PCB manufacturing. The results of the micro-sectioning analysis can improve processes and produce quality products.

Micro-sectioning analysis can reveal many defects, including defects in copper foils, board thickness, solder masks, and pads. Manufacturers can use this data to improve their processes, verify processing steps, and increase layer counts.


In-circuit testing (ICT) is a common test method used by PCB manufacturers. This test checks individual components and their connections to the substrate. It can also be essential without applying power. Once the testing is complete, the manufacturer will receive a test report containing detailed information about the components and their interconnections. The report will also include details about the probes, wiring configurations, and coverage measurements. Based on the results, the manufacturer can make adjustments.

ICT is a versatile tool that can be helpful on many PCBs. This tool relies on a special fixture, also known as a “bed of nails,” with multiple contact pins that come into contact with circuit nodes on the PCB. These contacts measure the performance of the components. In addition to measuring the function of analog components, ICT tests digital circuits’ functioning. However, full circuit testing is not usually possible due to the complexities of the board thickness.

Flying probes

Flying probes are becoming a common tool for PCB assembly manufacturer testing and are an excellent alternative to traditional mechanical fixtures. Designed for prototyping and low-volume production runs, they are a cost-effective way to verify the quality of printed circuit boards without the need for permanent fixtures.

Flying probe testing has many advantages, including low cost and a short development time. It also offers an added level of test validation with minimal impact on overall assembly. It also accommodates PCB assembly layout revisions without requiring test fixture modifications. All that is needed is a simple programming change in the software. Flying probe testing is also a viable option for large-size boards that would be difficult to test using a traditional ICT system.
