4> The principle of
winding copper sheet:
The principle of
winding copper sheet generally has the following ways:
A No lead is
connected in one circle. The head and tail should
not be
short-circuited. Insulation materials should be used to
isolate the head
and tail.
B. The width of
the tape must be larger than the width of the copper sheet.
C Two copper leads
for more than one turn.
D Copper piece of
middle drawout type, three leads.
5> Richard line
1) Vertical line
management standard
A thin line and
thick line should be trimmed for more than one
turn, and the
position of the trimming line should be between
2/3 of the height
of the base and the boss (if insufficient,
increase the
number of winding).
The length of B
thread should not exceed half of the distance
between two
adjacent feet and the longest length should not
exceed 1mm.
C Multiple groups
of lines and wound the line. The thin line
should be placed
on the top layer and one strand should not be finished before the other strand.
D If there is a
sleeve, the length of the sleeve should not be
lower than that of
the base
E For the same
slot and different feet, the same direction and
winding.
2) Horizontal line
management standard
(A) The thread
should be evenly distributed on the feet, and the thread should be at least
more than half of the foot (if there is not enough, increase the number of wirecoils to make up, but
not more than the
length of the foot).
B Trim line from
the root of the foot to the spiral upward and at least a full circle.
C The length of
the thread should not exceed half of the distancebetween two adjacent feet and
the longest length should not
exceed 1mm.
D Multiple groups
of lines and wound the line. The thin line
should be placed
on the top layer and one strand should not be cut before the other strand.
E When trimming
cables with different feet in the same slot,
wrap them in the
same direction. The length of the bushing
should not be
lower than that of the base and not close to the PIN.
