Do you know what ipc electronics standards are?For those who work in the electronics industry or PCB assembly may wonder if there is a fixed standard to ensure the quality of my products and if there is a common language for this industry. The solution to all these problems is the IPC standard.
So what is the IPC standard and who developed it? Are there any benefits to using it? What should I know about my electronics? Next we will describe these issues in detail.
Who developed the IPC standard?
Before we can understand the IPC standard, we first need to know who developed it. It comes from the IPC Association, a trade association whose goal is to standardize the assembly and production requirements for electronic devices and components. Founded in 1957, it was formerly known as the Institute of Printed Circuits.
Its name was changed to the Institute for the Interconnection and Packaging of Electronic Circuits to highlight the expansion from bare boards to packages and electronic assemblies. 1999 saw the organization’s official name change to IPC, with the tagline “Association Connecting Electronics Industries “.
From the history of the IPC Association, we can briefly understand that the IPC standard has included the requirements for the manufacturing and assembly of electronic products.
What is the IPC standard?
The IPC standard is the most widely recognized acceptability code in the electronics industry. The organization publishes standards for virtually every stage of the electronic product development cycle, including design, procurement, assembly, packaging, and more.
So another thing we know from this short introduction is that IPC standards refer to everything in the electronics industry and are essential knowledge for designers and manufacturers alike.
Just like the IPC standards tree, there are a huge number of standards that have been developed for different aspects and all of them are for end products. For example, IPC-A-610, which focuses on the acceptability of electronic assemblies, is used worldwide by OEMs and EMS companies.
Why use IPC standards?
After reading the IPC standard tree, some of you may reject this standard because of its complexity and triviality. This kind of thinking is not desirable. We must be clear about the benefits that IPC standard can bring.
(1) Quality Assurance and Product Reliability
As we said before, the IPC standard touches on everything in electronic products, such as IPC-A-600 for the acceptability of printed boards, and even lists the material requirements for copper foils, soldermasks, and stencil designs in IPC-4562, IPC-SM-840, and IPC-7525, 7526, and 7527, respectively. Because it establishes standards from all aspects, as long as they are applied to the production process of electronic products, manufacturers only need to follow the standards strictly, product quality and reliability are naturally guaranteed.
(2) facilitate communication
IPC electronics standard is the most widely used terminology in the electronics industry, which describes and demonstrates almost all the engineering problems. ipc standard with the computer industry common C language, in the electronics industry also has a similar status. Because it is widely used, people can understand each other well, thus ensuring that communication is barrier-free.
(3) Guarantee production
Generally speaking, each PCB manufacturer formulates its own production and quality standards accordingly to the IPC standard. All production line workers are trained in technical knowledge, so workers in each position can basically understand and comply with the production guidelines. As for all managers, they have received professional education on IPC standards and have experienced so many projects in their career. From all these aspects, all production processes are operated by professionals and tested in all aspects according to IPC standards as a way to ensure smooth production.
(4) Cost Savings
Due to the wide applicability and acceptance of the IPC standard, engineers and designers know how to test the finished product, and manufacturers know what requirements they have to fulfill and meet the agreed upon special standards. Almost all companies have a QC department and all employees have a deep understanding of what the product should look like. For consensus and mandatory requirements, we don’t need to engage in constant experimentation to know which materials are appropriate, and can avoid excessive trial and error costs, resulting in a significant savings.
(5) Branding effect
Affected by the sluggish market environment, we are always exploring new things and expanding our supplier network. But we were also concerned about the qualifications of our new suppliers and were not sure if they were reliable. Suddenly, we know that they have established a quality management system in accordance with IPC standards. In this case, we are slightly reassured that we can give them a try. This is the brand effect brought by IPC standard, which can realize the strategic goal and create a win-win situation, bringing more business to suppliers and better competitiveness to buyers.
What is the essential knowledge of IPC standard?
Before answering this question, we must understand the necessary processes for the production of PCBA. PCBA, an acronym for Printed Circuit Board Assembly, is an electronic product or production process by placing electronic components on a bare board or PCB. The main technologies used are SMT and DIP. almost all IPC standards are applied throughout the production process. For example, there are standards for stencil design and the materials used in SMT.
According to the definition of IPC standards, products can be categorized into three levels.
IPC Level 1 standards, which are primary standards, have the shortest lifespan and simplest functionality.
IPC Level II standards, which represent service electronics or specialized products with high performance, high reliability and long life.
IPC tertiary standards, which represent high-performance electronic products, are used in special industries such as military, medical and aerospace.
The Scope and Importance of Specific IPC Standards
