IPC SM-840D-2007
Qualification and Performance Specification of Permanent Solder Mask
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, T and H, to re?ect functional performance requirements and testing severity based on industry/end use requirements. Coverage is given to adhesion, material qualification, resistances to solvents, and electrical requirements. Revision D incorporates resistance requirements to lead free soldering processes.
