PCB Assembly and Design steps

According to the customer’s idea and the required electronic circuit in various fields, the design and assembly of printed circuit boards are done. This is done in the following five steps.

PCB Schematic Design

Schematic design is the first step in designing Uzita electronic board. To begin with, the main idea of ​​the board usage and then the different parts of it are identified with various tasks. A variety of software is used to design the schematic of electronic boards. The software of Uzita team is Altium.

PCB Design

The selection of Uzita electronic board inputs such as actuators, sensors, controllers, and power supply is done according to the board’s purpose of designing. After determining each of this equipment, the initial circuit design is determined. In this case, by placing each of them in the right place, the relationship between them and the needed resistance, inductors, and capacitors to assembly circuits is determined. The desired board design is then simulated in the software used by Uzita (Altium). By doing This, not only the accuracy of the circuit operation can be checked, but also the measurement of the circuit quantities, as well as the analysis of PCB design, be done.

Production of Printed circuit boards

After completing the design of the electronic board in Uzita Company, the production process of PCB printed circuit board begins. So that based on the schematic of the circuit and the parts used, the location of the parts, their connection paths, how the power supply lines pass, and the ground circuit are printed on the board with copper lines.

 PCB Assembly

As mentioned, after determining the main application of the circuit, the type of components is determined, after which the assembly process begins. At this stage, it is done in accordance with the design and the connection between different parts, their arrangement is done according to certain standards.

Testing and troubleshooting

Various tests are performed on electronic boards at Uzita to ensure proper connection and flow path. Some of these tests are: conducting line path test in PCB, testing the location of components with different bases such as diodes and transistors and ICs, etc., testing the accuracy of components such as capacitors, resistors, etc., component flow testing, and Other tests to be performed depending on the electronic board.

IPC Standards

Among the many electronics standards organizations, the organization that all designers should be aware of is IPC. These industry standards are designed to ensure the reliability and manufacturability of printed circuits (PCBs) and other electronic assemblies. The goal of the IPC standards is to ensure that electronics products are reliable, safe, and manufacturable. No matter which industry you work in, IPC likely defines standards that specify important requirements for your products.

Very few people have ever read the entirety of the IPC standards, simply due to their breadth and depth. If you are a PCB designer, there are some very important standards with which you should become familiar. When you use the right design software with integrated compliance tools, it may be easier than you think to comply with IPC standards and design to different IPC product classes. Altium Designer’s integrated design rule engine lets you define important IPC standards as design constraints, which helps you comply with these important standards.

IPC Standards on PCB Design and assembly

There are many sections of the IPC standards, and not all sections are applicable to every circuit board design. In addition, each standard is a very long document that includes a range of requirements for designers, manufacturers, or both. Some of the important IPC design standards include:

IPC 2221: Establishes some generic design and performance requirements in PCBs and other forms of component mounting or interconnecting structures.

IPC 4101: Defines material requirements for PCB laminate materials and other materials used to build stacks.

IPC 2152: A newer standard that defines current carrying requirements in copper traces and planes in a number of different applications.

IPC 4761: Covers design guidelines for via protection to ensure reliability, manufacturability, and quality.

IPC 6012: Defines generic performance requirements as compiled from IPC 2221, IPC 4101, and other quality requirements. The related IPC 6013 standard applies the same ideas to flex circuit boards.

IPC-A-600 series: Defines acceptance metrics for PCBs, as well as the three standard IPC Classes for various PCBs assemblies.

IPC 7351: Specifies footprint and land pattern requirements for SMT components. Component manufacturers use these specifications when designing their land patterns to ensure solderability and reliable electrical connections.

IPC-1752A: Material Declaration Management standard defines reporting formats for data exchanged between designers, distributors, and manufacturers.

Arrangement of PCB parts in the design and assembly

The order of placement, the alignment of the direction and height of the parts, the arrangement of the heating parts, etc. are among the notable issues in the IPC standards that are examined. The arrangement of the parts together has a great effect on their performances. So that in making Uzita electronic board, first the parts of higher importance are placed, then the resistors, capacitors, etc. are connected.

High-current electronic components generate a lot of heat during operation. For this reason, it is better to be in the center of the board at the time of design. Sensitive components such as capacitors, resistors, etc. should be kept away from large and hot equipment. Because their function can be disrupted.

Uzita electronic boards

Uzita company, with sufficient knowledge and experienced team, has been able to produce very practical boards such as U10 parking jack board, AC and DC motor holder, and smart TV board. In the following, the capabilities of each board will be examined. It should be noted that these boards are limited examples of the capabilities of the Uzita team in designing and assembling various types of PCBs, and our experts are ready to accept any customer.
