How to Download IPC-SM-840 Solder Mask Specification PDF
If you are looking for a reliable and comprehensive source of information on solder mask materials and performance, you may want to download the IPC-SM-840 solder mask specification PDF. This document, developed by the IPC (Association Connecting Electronics Industries), provides qualification and performance criteria for permanent solder mask and flexible cover materials used in printed board fabrication and assembly.
In this article, we will explain what IPC-SM-840 is, why it is important, and how you can download it for free.
What is IPC-SM-840?
IPC-SM-840 is a standard that specifies the requirements and test methods for solder mask materials, such as liquid photoimageable (LPI), dry film, screen printable, and flexible cover materials. It covers aspects such as adhesion, solderability, electrical properties, chemical resistance, flammability, thermal shock, and environmental stress. It also defines three classes of solder mask performance: T (general purpose), H (high reliability), and P (plated through hole).

IPC-SM-840 is intended to help printed board manufacturers and users select the appropriate solder mask material for their applications, as well as to ensure the quality and reliability of the finished product. It also provides guidance on how to design and test printed boards with solder mask.
Why is IPC-SM-840 important?
Solder mask is a vital component of printed boards, as it protects the conductive traces from oxidation, corrosion, and bridging during soldering and handling. It also enhances the electrical performance and mechanical strength of the board, as well as its appearance and identification.
However, not all solder mask materials are created equal. Depending on the type, composition, thickness, curing method, and application process of the solder mask material, its properties and performance may vary significantly. Therefore, it is essential to have a standard that defines the minimum acceptable criteria for solder mask materials and their evaluation.
IPC-SM-840 is such a standard. It provides a common language and reference for printed board manufacturers, suppliers, customers, and testing laboratories. It helps to ensure consistency and compatibility among different solder mask materials and processes. It also helps to avoid potential failures and defects caused by improper selection or application of solder mask.
