Canopy
Systems for Component Hold Downs
|
|
 |
AGI offers three Canopy systems for the PCB manufacturer who needs to hold down and/or align components, connectors or mask openings in the pallet, during the Wave Solder process. Which approach is best for your application depends upon the ergonomics of your application, and the proximity and types of components you need to hold down.
Pop-Up Hinged Canopy eliminates the problems associated with the angular loading of the component hold down tooling due to the fixed hinge point. The pop-up mechanism keeps the canopy up above the components after it has been swung over. This allows the
canopy to be closed, engaging the components, in a true vertical motion. The
operator simply presses downward and the canopy is locked into place with the
two Slam Latches. This approach ensures that no binding occurs and the components
on the PCB are correctly seated and aligned with a true vertical motion. |

All
of our canopy systems feature our Slam Latch. The latch allows for an easy
snap in place and release, without the repetitive motion of rotary hold
downs. The latch is a spring loaded mechanism, and is injection molded from
our high temperature ESD safe plastics for long life. |

presses downward to engage the canopy with the slam latches.
Simultaneously, the plungers and other tooling engage components to be held
down and/or aligned.

AGI’s
canopy systems also feature our spring loaded Plunger Hold Downs. They
are injection molded with our unique high temperature ESD safe plastics.
We offer a variety of spring forces from ½ up to 12 pounds depending
upon the application. |

Removable Canopy
This is our lowest cost approach and gives the user the ability to create true vertical motion.
The canopy can be locked in place with either rotary latches (shown) or our Slam Latches for easy snap in place. The canopy is keyed to ensure it is in position prior to touching any components.

|
|
|
|
|
Hinged Canopy or Hinged Hold Down Bar, features our Slam Latches for easy snap in place. The canopy may include radiused plungers to reduce any binding as the lid is swung into position.
This type of canopy is best for; holding
down the PCB, or masking the PCB and
connector hold downs that are located
greater than 4" - 6" from the hinge point. |
|
|
|
|
Canopies
are typically fitted with tooling to properly seat and align connectors,
capacitors and other components that need to be secured, orientated or aligned,
during the wave solder process. Consult with your AGI Sales Engineer to
find out which approach is best for your application. |
