(A)
•
• Using the Z-Axis Height Adjustment Wheel, lower carrier to allow Carrier Arms to touch side of Flow
Well.
•
Adjust Flow Well parallel to carrier arms or use edge of a pcb as a guide to square the flow well as
shown in photo.
Adjusting PCB Height:
• A space of approximately 1/16” between the top of the flow well and the bottom of the pcb. Molten
solder needs to flow through this space, contact all leads and flow freely back into the solder pot.
Use Z-height adjustment wheel to adjust.
• PCBRM System 5.2 – Once height is set, loosen and then lock the z-height adjust (A). Once set,
unit is set for repetative processes.
