Fine Adjustment Work Platform
Fine Adjustment Table
The Fine Adjustment Table facilitates the installation of fine pitch SMT components. The table can hold your PCB
(up to 45.7cm X 45.7cm (18" X 18")) assemblies in position for rework. Fine adjustment x & y axis controls allow
easy component to land pattern alignment. Following is a description of the features. Refer to the illustration.
Parts Identification
À
PCB Clamp Assembly (2) - Holds PCB assembly on Fine Adjustment Table.
Á
Clamp Assembly Locks (2 on each Clamp Asembly) - Locks PCB in place preventing X-axis (side to
side) movement along the 2 metal slide rods. Two locks on each PCB Clamp Assembly must be fully
depressed to allow clamp movement along the slide rods.
Â
Y-Axis Fine Adjust Control - Allows fine adjustment of Y-Axis (front to back) table position.
Ã
X-Axis Fine Adjust Control - Allows fine adjustment of X-Axis (side to side) table position.
Ä
Y-Axis Stop (2) - Memory retention feature allows Y (front to back) directional stop reference for
repeatable PCB positioning.
Å
Y-Axis Locks - Locks Y-Axis Stops in place.
Æ
X-Axis Lock - Locks the metal slide rods in position to prevent X-Axis (side to side) movement.
Ç
Theta Lock - Locks table in position to prevent Theta Rotation.
Operation
1. Install the PCB to be repaired/reworked in the following manner.
a) Press the 2 Clamp Assembly locks on each PCB Clamp Assembly. Adjust the spacing of the 2
PCB Clamp Assemblies to the size of the PCB.
b) Orient the PCB as desired and insert side edges into the "V" grooved slot at the top of each PCB
Clamp Assembly. Slide PCB into clamp assemblies.
c) Adjust the PCB Clamp Assembly on the Right side of the table toward the PCB to apply a slight
spring pressure. Depress item
Á
Clamp Assembly Lock to release Clamp Assembly
2. Adjust the coarse center position of the PCB rework area relative to the ThermoFlo handpiece and
Nozzle in the following manner:
a) Lower the Nozzle to a position just above the PCB.
b) Position PCB in PCB Clamp Assemblies (item
À
) with rework area centered (front to back).
c) Turn the X-Axis Lock knob (item
±
) counterclockwise to free side to side movement of the metal
slide rods (and PCB). Move metal slide rods to position component rework area beneath
ThermoFlo handpiece and Nozzle. Turn the X-Axis Lock knob clockwise to lock in position.
d) Repeat 2a and 2b as necessary to center component rework area under Nozzle.
