Brother Pe-150 Service Manual page 3


Most processes in the manufacturer of LSI devices such as microprocessors involve MOS (metal oxide
semiconductor) technology. It is thus necessary to take extreme care to prevent erasure or other damage caused
by static electricity during the use and manufacture of products using such LSI devices.
This embroidery machine is manufactured and assembled under a strictly controlled system preventing such
damage.
Similar care is also required during the service and maintenance of this product.
Please be sure to observe the following.
1. Always wear rubber gloves when handling the circuit boards. Never touch metal components with your bare
hands.
2. Ground your body to prevent static charge build-up.
3. When storing and shipping circuit boards, always wrap the circuit board in the specified aluminum foil
wrapper or equivalent static-prevention bag, and protect the circuit board from physical shock.
4. During adjustment and repair, do not touch or damage the circuit board with a screwdriver or other tool, and
do not touch the circuit-side of the board.
