SECTION A-A
KEY:
217 SERIES
Compatible with surface mount technology (SMT) automated production techniques for ease of assembly and a vari-
ety of soldering methods, these heat sinks allow greater packaging densities and reduction in PC-board area, increas-
ing the power dissipation of surface mount devices (SMDs) while maintaining and improving manufacturers'
component thermal specifications.
FEATURES AND BENEFITS:
• No interface material is needed
• Copper with matte tin plating for improved solderability and assembly
• Both the component and the heat sink are installed on the PC-board utilizing
• EIA standards and ESD protection are specified
• Can be used with water soluble or no clean SMT solder creams or other pastes
NOTES
1. Material to be “ESD”
2. Approximately 6 Meters per Reel
3. 250 Pieces per Reel.
