Part No. 4005.00.906 5-17
External Heaters maintain
uniform heat on large flow wells.
Locating Pins accurately position the lead
pattern over the solder wave.
Four boards processed.
Two areas processed.
5.9.2 Application Specific Tooling Provides the Most Efficient Process Solution
Send your board to Air-Vac for quick assistance to enhance your process and improve productivity. A
three-dimensional tooling model can be forwarded to you for viewing.
Fixtures allow multiple boards or areas to be soldered in one cycle using the y-axis stop. All boards are preheated
at the same time. Fixtures can also be used to hold irregular shaped boards or support flexible assemblies.

5.9.3 Standard Flow Wells & Air Cleaning Hoods
The flow well must be larger than the component lead pattern to insure that all leads are within the
solder wave. Generally an edge distance of 1/16” is added around the lead pattern and on long
connectors where heat dissipates at the end of the well, an edge distance of 3/16” is recommended.
Note:
NORMALLY CLEANING HOOD DIMENSIONS ARE THE SAME AS FLOW WELL DIMENSIONS. WHERE
DENSITY AND/OR ADJACENT COMPONENT CONFIGURATIONS PRESENT AN INTERFERENCE
PROBLEM, HOODS CAN BE MODIFIED TO MORE CLOSELY CONFORM TO LEAD PATTERNS.

Flow Well Sizing
• The size is basically determined by the component pin centerline distances.
• The contact area must include every lead of the pattern to be contacted by flowing solder. The
length and width dimensions must provide generous heat contact and ease for operator
component positioning.
