7.9 What to note when refilling components
The refilling of components with and without a barcode is described in chapter 4, section 4.1. 7
Å With tape feeder modules, make sure that you always splice on a new tape early enough so
that the feeder modules do not run out of components.
Å However, do not splice the tapes too early because if you wind the tape onto the new reel after
splicing the end of the old tape, the reel with the new tape may be over-filled. The tape could
then slip off the reel and become tangled. Under certain circumstances, this could cause pick-
up errors and prolonged down times.
Å Always insert shafts when using large tape reels and make sure that the dividing plates are
inserted correctly (see Fig. 7.5 - 2
).
7.10 Tools for the operator
All operators are to be equipped with the tools listed in the following. It is recommended to store
the tools in an appropriate container to avoid being injured when removing the tools from the con-
tainer (i.e. by a pair of tweezers). 7
Every operator of the machine requires: 7
– SMD tweezers
– A brush with short bristles to clean the component tables
– A set of small regular and Phillips-head screwdrivers
– A tape splicing clamp and splicing materials
– Scissors for splicing tape (do not use multi-purpose scissors or diagonal cutters)
– Erasers or fiberglass pens to remove fiducials
– Indelible pens for marking the tracks
– Cleaning agents (ethyl alcohol, Plexiglass cleaner, cotton wool tips, lint-free cloths,
pipe-cleaners)
– WD40 corrosion protection
– Vacuum cleaner

7.11 Operator profile
The operating personnel are to be assigned the following tasks:
– Supplying the feeder module with sufficient components
– Checking to make sure that the right components are placed in the feeder modules
– Promptly refilling the components and splicing the tapes
– Checking to make sure that the components are in their correct pick-up positions (see
Fig.
7.8 - 1
)
– Checking the flow of material to the PCBs on the input and output conveyor
– Checking the quality of the PCBs
– Random sampling of the PCBs before they enter the soldering furnace.
– Observing the EGB regulations
– Avoiding errors (see sections
7.7.1
and
7.7.2
)
– Noting error displays and messages on the station and notifying the line engineer, if necessary
– Carrying out the maintenance work specified in the User Manual
