Arranging Backup Pins
1. Determining the positions of the backup pins
When you place the backup pins, you should avoid the hole
in the PCB.
Step 1.
Place the master PCB in the conveyer.
Manufacturing master PCB
ㆍ Master PCB prevents interference between backup pins and parts.
ㆍ For a double-faced PCB, a master PCB is manufactured which has
a hole in the bottom area where the parts are mounted.
Warning
Before removing the backup-pin, power off the motor.
Step 2.
Arrange backup pins.
① Place the backup pins on both sides where the PCB is bent the least.
② Place the backup pins where the parts are mounted in the central area .
The number of backup pins
ㆍ For a 200 mm-wide PCB, usually 6 backup pins are used.

2. Setting the height of backup pins
You should set the height of backup pins after securing the
master PCB in the conveyer.(Height of backup pin: 132.3
mm in general)
Step 1.
Set the height of the backup pins in the sides.
Set the height so that the pins are in contact with the sides of the PCB.
Step 2.
Set the height of the backup pins in the central area.
Set the height of the central backup pins so that they are on the same level with
the pins on both sides.
