Choosing The Correct Desolder Cartridge - Metcal MX-500 Manuel D'utilisation

CHOOSING THE CORRECT DESOLDER CARTRIDGE

Proper tip cartridge selection is important for getting the best results from your
Metcal System. Choosing the right tip cartridge will maximize your performance at
the lowest possible temperature. Since changing tip cartridges is so quick and easy,
there is no need to compromise.
Select a tip with an inside diameter larger than the lead diameter. Select a tip with an
outside diameter that is approximately the same size as the pad.
C O R R E C T
A standard STDC cartridge can desolder a maximum lead length of 0.0170." For fast,
safe removal of devices that are difficult to reach on densely populated boards, or to
remove long pin connectors, try the STDC long reach cartridges. They are identical to
standard STDC tip cartridges, but with a 0.46" long extension at the tip.
CHOOSING THE CORRECT TEMPERATURE (SERIES)
Start with a 600 Series cartridge, switching to a 700 Series only where absolutely
necessary; for example, when working with ground planes or multi-layer boards. For
long reach tips, start with a 700 Series cartridge.
For extremely heavy loads tied to ground planes, or very thick multi-layer boards, 800
Series cartridges may be necessary.

*When using long reach cartridges, 600 Series heat delivery is insufficient for fast, safe device removal.
Therefore, long reach desolder tips are only available in 700 and 800 Series.
