Part No. 4005.00.906 5-16

For double-sided boards, solder flow is directed

away from adjacent bottom-side components.

For edge connectors, solder flows away

from the board.

(B)

(A)

The solder flow can be directed inward,

Protecting components near the lead pattern and

limiting heat to adjacent area or components.

The solder flow can be directed to large

select areas for multiple soldering of

components.

5.9 Tooling

5.9.1 Special Soldering/Desoldering Applications

• Special Flow Wells and Cleaning Hoods can be manufactured for specific applications where

issues of clearance, adjacent components and mixed technology boards are concerns.

• Consult Air-Vac for details concerning your specific requirements and the optimum solution.

• A detailed dimensioned customer print and sample of the assembly are critical to design.

Flow Wells determine the size, shape and direction of the solder wave:

• Bottom side critical areas must be addressed. Edge distances (A) and height of bottom side

components (B) must be known.

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.
