CARTRIDGE OVERVIEW

a. About Metcal Cartridges

The  soldering  and  rework  cartridges  are  constructed  with  a  tip,  heater,  coil, 
connector and shaft. This assembly is designed for precision and long life provided 
that the proper tip care procedures are followed. (See Section 8) 
Selecting a cartridge depends on the following variables 

Need for access

Type of solder

Size and mass of load

Componenet type

The  correct  choice  of  cartridge  will  result  in  an  optimized  soldering  process.  Here 
are some of the considerations for selecting the soldering or rework cartridge. 

b. Choosing the Correct Tip Geometry

Metcal cartridges come in a wide variety of tip geometries and temperature ranges

.

These tip geometries cover a broad range of tasks from delicate

 

precision work to

heavy ground plane soldering.

1. Pick  a  tip  that 

maximizes  contact  area

  between  the  solder  joint  and  tip.

Maximizing  contact  area  gives  the  most  efficient  heat  transfer,  producing
high quality solder joints quickly.

2. Pick  a  tip  that  allows  good  access  to  the  solder  joint.  Shorter  tip  lengths

allowquicker  response.  Longer  or  angled tips may  be  needed  for  soldering
densely populated boards.

3. Pick the lowest temperature tip cartridge that will accomplish the task. This

minimizes  the  potential  for  thermal  damage.  The  temperature  series  is
marked on the shaft of the Heater Tip. (See page 8 for more Information)
