Printed Circuit Board Specifications
PC boards must meet the requirements outlined below.
• Minimum Board Thickness: 0.79mm (0.0312").
• Maximum Board Thickness: 2.36mm (0.0937").
• Allowable Board Dimensions: See tables below.

Insertable Area 483mm (19.0") 406mm (16")
* Insertable area is reduced if special Dynapert/Amistar
compatible rotary disk is selected.
Component Lead Hole Specifications
Recommended hole diameters for optimum performance:
• HOLE DIAMETER = LEAD DIAMETER + 0.483mm
(0.019") + 0.08mm (0.003")
Holes smaller than the recommended size may result in reduced
insertion reliability. Holes larger than the recommended size may
result in loose components.
Holes used for board error correction should be 1.0 mm
+ 0.5 mm
(0.040" + 0.020"). Plated holes or translucent PCBs may affect
performance.

Insertion Rate Determination
The component insertion rate of the VCD/Sequencer 8 is up to
25,000 insertions per hour using standard and 5mm tooling, and
factory test specifications. This insertion rate includes an insertion
PPM of 200 or better.
To attain the maximum insertion rate, the X and Y axis move between
consecutive pattern steps must be no more than 7.6mm (0.300"). An
insertion span move greater than 5.08mm (0.200") will reduce speed.
In the Production Operation mode the machine will automatically
calculate the insertion rate for each PCB processed and display this
value when the PCB population is complete. This actual insertion
rate includes all table rotations from first insert to last insert of a
product (program). It does not include Load/Unload time.
Maximum Allowed Warp Up or Down: 0.07 mm/cm, up to 3.17 mm
(0.007"/inch, up to 0.125")
