Pattern configurations
(Inductor layout on panelized [breakaway] PC boards)
1. After inductors have been mounted on the boards, chips
can be subjected to mechanical stresses in subsequent
manufacturing processes (PCB cutting, board inspec-
tion, mounting of additional parts, assembly into the
chassis, wave soldering the reflow soldered boards etc.)
For this reason, planning pattern configurations and
the position of SMD inductors should be carefully per-
formed to minimize stress.
1-1. The following are examples of good and bad inductor layout; SMD inductors
should be located to minimize any possible mechanical stresses from board
warp or deflection.
Item
1-2. To layout the inductors for the breakaway PC board, it should be noted that
the amount of mechanical stresses given will vary depending on inductor
layout. An example below should be counted for better design.
1-3. When breaking PC boards along their perforations, the amount of mechani-
cal stress on the inductors can vary according to the method used.
The
following methods are listed in order from least stressful to most stressful:
push-back, slit, V-grooving, and perforation. Thus, any ideal SMD inductor
layout must also consider the PCB splitting procedure.
