PCB assembly, or PCBA, can be a difficult idea to grasp because it is not the same as printed circuit board manufacture or PCB assembly service. These are two distinct specialties with their own set of rules and regulations. The process of obtaining circuit assembly parts populated to the bare PCB, where Surface mount Mechanism or SMD parts settle on the PCB surface and Through Hole Device or THD parts are inserted in the conductive holes, is known as PCBA or PCB Assembly. If you're concerned about your PCB assembly, please keep an eye on us for professional advice and information. I hope I was able to assist you to order PCB assembly services.

What are the tips for ordering PCB assembly?

Let's take a glance at some Assembly process pointers now. These pointers will help you achieve your goals. The trick is to be cautious and to plan ahead of time

 1. Pay close attention to the file formats

Choose a supplier who has worked with the type you intend to employ before. It's important because not all manufacturers can handle all file types. The two most widely used alternatives are Gerber and CAD. The boards of today are quite complicated. To achieve the desired level of precision, numerous layers of electronic components, vias, and traces must fit properly.

PCB file formats aren't the most fascinating aspect of PCB design, but they're necessary. Gerber is the most widely used and accepted format. As a result, a huge number of assemblers provide it. CAD files, on the other hand, are created using CAD and other similar applications.

They adhere to the OBD++ standard, but you may also come across those that adhere to the less common IPC-2581 bar. So that there are no problems afterward, discuss these criteria with the manufacturer.

2.      Make contact with your PCB assembly company

It doesn't matter how good of a business relationship you have with your Printed circuit board assembler; you must speak with them before proceeding with the process. At the design stage, we recommend that you speak with your assembler. It might provide you with useful design advice.

Many people make the mistake of contacting their assemblers at the last minute. It might be a huge blunder. Speaking with your assembler ahead of time will help you learn more about the industry and the many techniques and processes accessible. 

They can inform you about the most recent PCB assembly trends and assist you in making the best decision possible. Plus, working with your assembler ahead of time can help you establish a solid connection that will come in handy when you go to the assembly method.

3.      Keep an eye out for offshore providers

Many individuals choose foreign assembly since it is less expensive. Offshoring, on the other hand, comes with a slew of dangers. Assemblers have been known to use parts that aren't up to snuff. This can help you save money in the short term, but it can also harm you in the long run. You may wind up spending more money as a result of offshore, making it a poor choice.

Aside from that, there may be problems, such as mass production delays that cause service outages. Even a minor hiccup might wreak havoc on your timeline. As a result, it's critical to be cautious while working with offshore assembly companies.

4.      Don't rely on a single vendor

Don't make the error of relying on just one vendor. Always have a contingency plan in place. Furthermore, it would be beneficial if you were cautious when constructing the board. Make sure you don't use any parts that aren't easily available.

5.      Consider giving pieces names and labels

We're trained to mark and label design documents, but few of us are taught to sketch and label the components. All parts that you provide with your box must be labeled, numbered, and matched up. They should be stated extremely clearly so that there is no room for error.

6.      Don't forget to test your design for fabrication

DFM stands for design for manufacturing and is an engineering test or procedure that explains engineering or designing a product to make the manufacturing process easier. It assists in lowering associated costs and making the transaction more realistic.

DFM can also assist in identifying and resolving any issues, ensuring that the process runs smoothly. It is employed in practically every engineering sector, including PCB assembly services. A DFM inspection verifies that the finished product meets the required standards. Spacing concerns, first pin indication, footprint verification, and part polarity are just a few of the issues that can arise.

To ensure that a DFM review produces accurate results, you may need to recruit professional engineers. If you lack the necessary equipment, experience, or skills, you may not be able to review on your own.

DFM reviews are also available from some PCB assembly companies. Inquire with your service provider to see if they offer such services. It ensures that you will not have to worry about testing or finding someone to do the necessary tests.

7.      All trade-offs should be double-checked

Technology evolves at a breakneck speed. That's wonderful for business because it means we can get more done with less effort now. There will, however, always be a trade-off. After all, we want to cram as many functionalities as possible into boards that are shrinking by the day.

As a result, you must know what you want from the board to obtain the necessary abilities. 

  • Do you desire more power and influence?
  • Do you want a more reliable transmission?

Study the board's core objective. It will assist you in determining the most important capabilities. Do not let the trade-off intimidate you. You may have to cut back on certain things, but you won't have to give up everything.

It's best to speak with your manufacturer and ask for suggestions on how to improve the design to match your needs. With additional features, a well-designed and manufactured board will provide more power and more reliable transmission.

As a result, it's critical to have a comprehensive understanding of your needs before beginning the production and assembly method to ensure that the end product fulfills your needs.

8.       bulk functional testing wave

You might be able to get a deal if you place a large order, but this isn't a good idea unless you're confident in the end product's quality. Before placing a large purchase, it is important to try out an assembler. It will ensure that you will have no problems in the end. Also, it's best to keep in touch with multiple assemblers so that you may switch to the other one if the initial deal falls flat.

To make a judgment, some experts recommend employing multiple assemblers and evaluating the finished product. It will offer you a good indication of how trustworthy a supplier is. It's not just about the final product. It's all about the total experience. Scheduling, for instance, can make a huge difference.

PCB manufacturing orders can be placed in three ways.

1. Combine PCB Assembly orders with PCB orders.

After making your PCB orders, select the assembly to fill in your assembly service settings by clicking on the "PCB fast quote" navigation bar. To choose a price, click Calculate, then Add to Cart and Submit Files.

2. Directly place Printed circuit boards Assembly orders.

In the instant quote bar, type the specifications of the PCB assembly you're quoting right now. Click quote now into the assembly quote, pick to fill assembly parameters, choose the item" select PCB Way's PCB order#" as "no". The system will then remind you to place your PCB order at the same time. To choose a price, click Calculate, then Add to Cart and Submit Files.

3. Make a PCB Assembly order for the PCB

In the instant quote bar, type the parameters of the PCB assembly you're quoting right now. Select "select PCB Way's PCB order#" as "yes" in the item "select PCB Way's PCB order#" in the assembly quote. The system will then prompt you to select PCB Way's PCB order. To choose a price, click Calculate, then Add to Cart and Upload Files.


The assembly procedure may be as simple as printing a PCB, adding elements and solder paste, and then entering the reflow oven. An illustration of white-box testing is in-circuit test (ICT), which involves using an electrical probe to examine a packed printed circuit board (PCB)Yet, automated assembly is necessary during the stage of production. Some companies develop their assembly lines, but it's more customary to have a second party assemble the PCB for you, ideally from the same PCB manufacturer. Tht assembly BOM is an important inventory of essential components in PCB board assembly, including many modules connected to the finalized PCB design, as well as troubleshooting techniques and board gripping guidelines.
