3.1.2. Tape Reel Loading
While loading tape reels on reel rack, the position of each tape reel should be aligned with its peel-box and feeder.
Methods of Tape loading：①Load the tape reel on reel rack；②Insert the tape into feeder；③Pull back the cover
tape from feed outlet；④ Pass the cover tape through pressure rod, then insert the cover tape into gear of peel box.

3.2. Maintenance
3.2.1. Reinforce Daily Maintenance
P&P machine is a relatively complex, high-tech and high-accuracy device that requires a extremely clean working
environment with constant temperature and humidity. Thus, it’s must to be strictly in accordance with regulations
of the equipment to have a routine maintenance.
3.2.2. Requirement for Operator
Operator should get the basic training which covers all the skills and knowledge needed to safely operate this
type of pick and place machine.
Operating strictly against equipment’s instruction. DON’T use machine with problems. Stop the machine
once malfunction appears and contact with the after-sales service staff, restart to work after problem solved.
Operator should be concentrated during the process.
Observation—to observe whether there is abnormal situation. For example peel-box can’t work, plastic tape
is broken etc.
Listening—to hear whether strange sounds appears during operation, such as noise of placement head, sound
of loss component, strange noise of conveyor etc.
Handwork—solve small problems in time, such as install feeder, correction placement position etc. If
anything wrong with the main machine body or circuit, please consult after-sales staff.
3.2.3. Formulate Measures to Reduce/ Avoid Mistake
The most easily appeared problem during mounting are components placement incorrectly and placement
misaligned. Refer to below measures for precaution.
1) It needs to check whether the components’ package is matched with related feeder. If not, please correct
them.
2) As for tape reel feeder, after one is ran out, operator must check whether another newly changed tape reel is
correct or not.
3) After import the SMD file or edit chip list manually, please recheck each component’s No., nozzle’s rotation
angle and placement position to ensure they’re correct.
4) Operator must check the first finished PCB of each file. If any problem happens, please find solutions such as
revise program to solve it.
5) Check placement position’s alignment, component loss problem during regular work from time to time. Find
the reason in time and come up with solutions.
6) Detect position before soldering(manually or using AOI)
7) To sum up, P&P machine’s running speed and placement accuracy still has limitations. Human plays an
important role in running well of the machine. So it’s necessary to comply with effective measures to ensure
machine’s well working, high placement quality and efficiency.
