1. Effective communication

There is nothing more important than clear and effective communication with your smt placement factory. In fact, when providing you with information about new product technologies, industry best practices, etc., they may be your valuable resource. As for communication within the company, please make sure that everything is clearly laid out. The code, polarity mark, etc. in each part should attract your attention. Also, please make sure not to swap the polarity marks between the positive and negative poles, especially the polarity marks of the LED. Also make sure that the reference indicator does not appear in channels and other locations where the text may be corrupted and difficult to read.

2. Structure

In order to ensure that there are no problems during the PCBA placement process, it is important to stick to the tested standards. For example, you want to check which PCB coating or copper is heavy. It is recommended to stick to 3 benchmarks with the same component orientation.

3. Production costs

It is best to find ways to optimize production costs as early as possible. However, it is important to measure the pros and cons associated with each decision. For example, local printed circuit board assembly may be a possible way to reduce costs. What you need to keep in mind is that there are risks associated with substandard parts, because this not only offsets the cost advantage, but also proves to be risky in terms of the company’s reputation. Another aspect to be aware of is the delay in timely delivery, as this can also have costly consequences.

4. Naming

Another very important thing to note is the marking of components in the design. Make sure that all components in the design are correctly labeled and numbered correctly. This will solve any problems caused by the difference in terminology.

5. Low-availability parts

You definitely don’t want a situation where the design is ready, but you cannot move forward because a particular part is not available or it is an exclusively purchased part. It is best to use widely available parts to avoid wasting precious time.

6. Circuit board efficiency

Increased circuit board efficiency requires you to stick to standard circuit board sizes as much as possible. For example, ideally 406mm x 508mm and 305mm x 457mm. Bigger doesn't always mean better. Although large boards are easier to route, they may mean increased costs. On the other hand, although small boards may be easier to inspect, they may increase costs due to the additional number of layers. Therefore, it is best to choose a standard size. Similarly, a well-designed component footprint is another requirement.

7. Pay attention to manufacturing issues

Placing large parts next to smaller parts may have heat dissipation issues. For example, a large part may not allow a small part of the solder to melt completely. Similarly, the inner copper layer can only overlap on a part. Paying attention to these heat production issues can ensure that there will be no errors that occur later than the suspension of the entire project.

8. Check all files carefully

Last but not least, carefully check all files before sending them. Ensure that the bill of materials has been updated. If you are sending a kit of parts, it will help to cross-check that the order of all parts and the part numbers are correctly marked.
