2.1.3 Safety instructions for laser units
Permission to operate assemblies that are classified as lasers is withdrawn if
●
Mechanical damage to the assembly is observed, or
●
The assembly mechanics, lenses or electrics have been manipulated. Even damaged or miss-
ing screw locking paint on laser assemblies (e.g. cover plates, fasteners, adjusting poten-
tiometer) counts as work.
●
Only ASM Assembly Systems Singapore Pte ltd service engineers or the machine owner's
service engineers, who have been trained by ASM, may replace laser assemblies.
●
Repairs to laser assemblies may only be performed by ASM Assembly Systems Singapore
Pte ltd at their factory.
2.1.4 Safety instructions on permanent magnets
Powerful permanent magnets are used for the linear motors of the gantry and inspection head
assembly.
DANGER
Strong permanent magnet fields
Fatal hazard: persons with active implants (e.g. pacemakers, defibrillators, insulin pumps,
etc.) are at risk from strong permanent magnetic fields inside the machine.
Persons at risk should avoid the immediate vicinity of the machine.
CAUTION
Danger of crushing
Danger of crushing for persons with passive metal implants (e.g. plates, screws).
► Do not reach or lean over into the machine when the protective covers are open.
► Do not bring any metal objects into the hazard area.
CAUTION
Strong permanent magnet fields
There is a risk that the strong magnetic fields could corrupt data on data media or check
cards.
► Keep sensitive data supports away from the permanent magnets.
NOTICE
Electric and Magnetic Fields (EMF) level of the machine
The EMF level maximum value is less than 500 milli gauss inside the machine front (oper-
ator side), rear, left and right.

Please note the following points when working on the permanent magnets:
► People with active implants (e.g. heart pacemakers) or other ferromagnetic prostheses are ex-
pressly prohibited from working on or coming near these devices. Always keep a safe dis-
tance from the linear motor.
► The powerful magnetic forces of attraction mean that particular caution is needed in the imme-
diate vicinity of the magnet track and of the moving primary part. Never move heavy or wide
objects made of steel or iron manually into the vicinity of the magnet track. The magnetic force
of attraction is not visible, so its effects in the vicinity of the magnet track are generally under-
estimated. The magnetic attraction can start suddenly, and can reach several thousand New-
tons in the vicinity of ferromagnetic objects (made of steel or iron) of similar size to the magnet
track.
► Always wear suitable work and protective clothing (e.g. gloves and safety shoes, etc.) when
handling the magnet track.
► Only suitably trained ASM SMT Solutions Team engineers may carry out assembly work and
other tasks when replacing the magnet track.
