Qualification and Performance Specification of Permanent Solder Mask and Flexible Cover Materials
Establishes the requirements for the evaluation of liquid and dry film solder mask material and for the determination of the acceptability of use on a standard printed board system. IPC-SM-840 provides two classes of requirements to re ect functional performance requirements and testing severity based on industry/end-use requirements. It covers adhesion, material qualification, resistances to solvents and electrical requirements. Revision E incorporates requirements for flexible cover materials used as a flexible dielectric protective layer over etched conductors and other conductive features.
