. This section describes the wetting of the solder to the physical part and the board itself. Keep in mind however, that a PEM ® nut is inserted into the board with an interference fit, so it will be secure

: We have a through-hole integrated circuit (IC) component that has good wetting when it goes through the wave soldering machine, and the solder climbs pretty far up the lead

. Non Wetting Or De Wetting Non-wetting is an SMT defect that occurs when the base metal surface on the board doesn’t accept the molten solder, creating a poor joint condition where a component’s terminals

: • Non-coplanar leads on the component • Excessive warpage of the PCB or substrate • Poor wetting • Insufficient amount of solder due to improper printing parameters
