ORDERING INFORMATION
• The 1578-X-57-15-00-00-03-0 Surface mount disc is .078” in diameter and available in
four heights from .025” to .055” +/-.002” tall.
Employing our precision machining expertise we are able to achieve at surfaces on
both sides of the disc with virtually no burrs. The at surfaces are ideal for surface
mount soldering and as the conductive mating surface for spring loaded pins and
connectors as well as test probes. The discs are typically placed on solder pasted PCB
pads and then subjected to reow soldering. Once soldered the terminals are ready to
be used as reliable, durable contact points.
• The 1578-X’s are packaged on tape & reel - 16 mm wide x 8 mm pitch, making them
simple to integrate into existing pick & place equipment and assembly processes. The
tape packaging is per EIA-481-D
• Custom sizes are quickly and easily achievable via Mill-Max’s high speed precision
machining processes. You can contact our technical support team to discuss your
particular application and requirements.
