Everything That You Need To Know About Printed Board Assembling Design Guide

There is no denying that a lot of effort goes into the PCB assembly for industrial products. After all, the engineers and designers have an extremely small board to work on it. They need to incorporate a lot of functionality within a limited space offered. After all, modern electronics are becoming compact, yet they offer diverse functionalities.

In addition, the manufacturing and engineering cost of Printed Circuit Boards is also high. After all, expensive software and tooling come into pay for the designing and production of the Printed Circuit Boards.

Therefore, a manufacturer cannot simply afford to create low quality Printed Boards, especially when they want to gain a reputation and name in the industry. In order to maintain the standard and the quality of the Printed Circuit Boards, there are a set of rules that a manufacturer needs to follow.

In this guide, we are going to provide you with the complete guideline to ensure the quality of PCB assembly for industrial products. So, without any further delay, let us get started!

Guidelines for Effective and Efficient Printed Board-Assembling Process

To ensure the smooth assembling of Printed Circuit Boards, the PCB designers need to fully comprehend all the requirements of the Printed Circuit Board assembly process. Most, the PCB manufacturer tends to see the design for assembly (DFA) as simple checks that they do see once they get the Printed Board design.

What they fail to understand is that these guidelines are way more than just simple checks. Below, we have listed the reasons why a manufacturer should pay close heed to these assembly guidelines. Also, we will tell you how your contract manufacturer would be able to help you yield better results.

Importance of PCB Design Assembly Guidelines

Regardless of what you are planning to do, may it be making a steak or cutting the grass, you want the end result as per your plans. The same rule applies to the assembling process of the Printed Circuit Board.

You really can’t go through a lot of trouble, put in a lot of time, effort and money, just to end up with a PCB that you do not desire. In addition to assuring that your PCB provides you with the desired outcome, you also need to cut down the manufacturing cost.

It is critical to maintaining quality, but if a PCB gets too expensive, it not worth all the effort. There are several things that you need to consider, in order to ensure that your board is manufacturable.

Here are some of the main problematic categories.


Sometimes the PCB demands some unique or not readily available parts. In this case, you might have to pay more in order to acquire these parts. In addition, there would be an increase in the expense, if a certain part is required more lead time. The delay in the board building would eventually result in higher prices.


PCB part placement has a direct impact on the price of the Printed Circuit Board. Therefore, manufacturers are always in search of ways to incorporate as many components as possible while keeping a close check on the cost.

The PCB solderability is affected by several things. For instance, the rotation of the components would have a direct impact on it.


Do remember that a PCB would eventually connect with interfaces or with other boards. In case, you do not consider this aspect of the PCB in your design layout, you would end up increasing the overall manufacturing cost of the PCB.

Therefore, to avoid the extra expense during the entire manufacturing system, pay attention to these factors during the design phase.

The balance between Cost and Design

In case the approved Printed Circuit Board design costs too much to develop, then you need to focus on the design. After all, there is no pointed creating a PCB that would cost you more in comparison to the profit it would yield.

Manufacturers believe that this mindset isn’t true for prototyping. But, they need to understand that prototyping would eventually lead to mass production. You would end up with the same problem, after spending money, time, and effort on creating the prototype of the respective product.

Therefore, it is important for the design to be optimized for the assembling process even during the prototyping phase. The lack of optimization would eventually lead to redesigning for mass production.

Thus, resulting in another expensive round of prototyping. Therefore, the safe option is to follow these practices and ensure the design integrity and optimization for the assembling process.

Design Guidelines for Printed Board Assembling Process

In order to ensure the smooth and seamlessly assembling of the PCB, you need to be familiar with the following guides.

Important Guidelines

It is important to use components for the PCB design that is readily available. Option for unique components might look impressive, but they would be extremely costly. In addition, the parts or the components that are going end of life, are not a wise choice. In addition to increasing the cost, they would even cost a delay in the building process.

When using Surface mount technology, try incorporating all the components on one side of the board. Mounting components on both sides of the board would make the assembling process challenging and they would even increase the stencil cost.

There can be a problem with the board solderability especially when you use tall or unusually sized parts. Therefore, we recommend that you use standard or smaller parts. Also, in case, you have used these parts, do not put the smaller parts right next to these components.

A good design technique to avoid placing the components near the edges to the board. This is extremely important for smaller boards. As it would help minimize the issues that manufacturers might have to face while taking these boards out of their panels.

Pay heed to the component orientation. Make sure that the diodes and the polarized capacitors are not facing different directions. Maintaining orthogonal placement is imperative to avoid problems in the PCB assembly for industrial products.

Place correctly oriented parts for the best soldering results.

To ensure proper and complete debugging and testing of the Printed Circuit Board, make sure that it has test probe points.

These are some of the many guidelines that a manufacturer needs to follow. Following the guides would help produce high, quality error-free PCBs.
