What is J-ST D - 0 0 1 and why is it important for soldered electrical and electronic assemblies?




J-ST D - 0 0 1 is a joint industry standard developed by IPC (Association Connecting Electronics Industries) that defines the requirements for materials, methods, and verification criteria for producing high-quality soldered interconnections. Soldering is a process of joining two or more metal parts by melting a filler metal (solder) that forms a bond between them. Soldering is widely used in the electronics industry to connect components on printed circuit boards (PCBs) and other electronic devices.


J-ST D - 0 0 1 is important because it ensures that the soldered connections are consistent, reliable, and meet the performance requirements of the product. Soldering quality affects the electrical conductivity, mechanical strength, thermal stability, corrosion resistance, and durability of the electronic assemblies. Poor soldering can lead to defects, failures, rework, waste, customer dissatisfaction, and safety hazards. Therefore, following the J-ST D - 0 0 1 standard can help improve the quality and reliability of soldered electrical and electronic assemblies.


What are the benefits of J-ST D - 0 0 1 certification for individuals and organizations?




J-ST D - 0 0 1 certification is a credential that demonstrates that an individual or an organization has the knowledge, skills, and competence to apply the J-ST D - 0 0 1 standard in their soldering operations. IPC offers various certification programs for different levels of expertise and roles in the electronics industry. These include Certified IPC Specialist (CIS), Certified IPC Trainer (CIT), Certified Standards Expert (CSE), Certified IPC Designer (CID), etc.

How to get J-ST D - 0 0 1 certification and what are the requirements?




To get J-ST D - 0 0 1 certification, you need to undergo a training and testing program offered by an IPC authorized training center (ATC) or an IPC certified trainer (CIT). The training program covers the theoretical and practical aspects of the J-ST D - 0 0 1 standard, including the material, process, and acceptance criteria for soldered electrical and electronic assemblies. The testing program consists of written and performance exams that assess your knowledge and skills in applying the J-ST D - 0 0 1 standard.


The requirements for getting J-ST D - 0 0 1 certification vary depending on the level and program of certification you choose. For example, to get certified as a CIS (Certified IPC Specialist), you need to have at least one year of experience in soldering or related fields, complete a 40-hour training course, and pass the written and performance exams. To get certified as a CIT (Certified IPC Trainer), you need to have at least two years of experience in soldering or related fields, complete a 40-hour training course, pass the written and performance exams, and demonstrate your ability to teach the J-ST D - 0 0 1 course to others. To get certified as a CSE (Certified Standards Expert), you need to have at least five years of experience in soldering or related fields, complete a 16-hour training course, pass the written exam, and demonstrate your expertise in interpreting and applying the J-ST D - 0 0 1 standard.


J-ST D - 0 0 1 overview




History and development of J-ST D - 0 0 1




J-ST D - 0 0 1 was first published in 1988 as a joint standard between IPC and EIA (Electronic Industries Alliance). It was based on the MIL-STD-2000A standard that was used by the US Department of Defense for military applications. Since then, J-ST D - 0 0 1 has undergone several revisions and amendments to reflect the changes and advancements in the electronics industry. The latest revision is J-ST D - 0 0 1H, which was released in 2018. It incorporates new technologies, materials, processes, and requirements for soldered electrical and electronic assemblies. It also aligns with other IPC standards, such as IPC-A-610 (Acceptability of Electronic Assemblies) and IPC-7711/7721 (Rework, Modification and Repair of Electronic Assemblies).


Scope and purpose of J-ST D - 0 0 1




J-ST D - 0 0 1 applies to all types of soldered electrical and electronic assemblies, including through-hole, surface mount, mixed technology, discrete wiring, cable and harness assemblies. It covers the requirements for soldering materials (such as solder alloys, fluxes, cleaning agents, etc.), soldering processes (such as preheating, soldering methods, cleaning methods, etc.), and soldering acceptance criteria (such as visual inspection, mechanical testing, electrical testing, etc.). The purpose of J-ST D - 0 0 1 is to provide a common language and understanding for the electronics industry regarding the quality and reliability of soldered interconnections. It also serves as a basis for training and certification programs for individuals and organizations involved in soldering activities.


Classification and categories of J-ST D - 0 0 1




J-ST D - 0 0 1 classifies the soldered electrical and electronic assemblies into three classes based on their end-use environment and performance expectations. These are:



  • Class 1: General Electronic Products - These are products that are suitable for applications where the major requirement is function of the completed assembly.



  • Class 2: Dedicated Service Electronic Products - These are products that are suitable for applications where continued performance and extended life is required, and for which uninterrupted service is desired but not critical.



  • Class 3: High Performance/Harsh Environment Electronic Products - These are products that are suitable for applications where high performance and reliability are critical, or where extreme environmental conditions may affect the product's performance.



J-ST D - 0 0 1 also categorizes the soldered electrical and electronic assemblies into four categories based on their design complexity and density. These are:- Category 1: Simple Printed Boards - These are boards that have a single layer of conductors, with or without plated-through holes, and a low component density.


- Category 2: Standard Printed Boards - These are boards that have two or more layers of conductors, with or without plated-through holes, and a moderate component density.


- Category 3: Complex Printed Boards - These are boards that have two or more layers of conductors, with plated-through holes, and a high component density.


- Category 4: Very Complex Printed Boards - These are boards that have two or more layers of conductors, with plated-through holes, and a very high component density.
