SKHH, SKPD Series Radial Type Items Surface Mount Type Conditions for Auto-dip Snap-in Type Notes 1. The above temperature shall be measured of the top of switch. There are cases where the PC board's temperature greatly differs from that of the switch, depending on the material, size, thickness of PC boards and others. The above-stated conditions shall also apply to switch surface temperatures. 2. Soldering conditions differ depending on reflow soldering machines. Prior verification of soldering condition is highly recommended.

Items Condition Preheating time 60s max. Soldering temperature 350 max. Soldering temperature 260 max. Duration of soldering 3s max. Duration of immersion 5s max. Capacity of soldering iron 20W max. Number of soldering 2times max. SKTD, SKTG, SKQJ, SKQK, SKEG Series SKQJ, SKQK, SKEG Series Items Condition Flux built-up Mounting surface should not be exposed to flux Preheating temperature Ambient temperature of the soldered surface of PC board. 100 max. Preheating time 45s max. Soldering temperature 255 max. Duration of immersion 5s max. Number of soldering 2times max. Notes 1. Prevent flux penetration from the top side of the TACT SwitchTM. 2. Switch terminals and a PC board should not be coated with flux prior to soldering. 3. The second soldering should be done after the switch is stable with normal temperature. 4. Use the flux with a specific gravity of min 0.81. EC-19S-8 by TAMURA Corporation, or equivalents. 265
