Pattern configurations
(Design of Land-patterns)
1. When capacitors are mounted on a PCB, the amount of sol-
actors, etc. may cause serious harm to human life or have
severe social ramifications. As such, any capacitors to be
used in such equipment may require higher safety and/or reli-
ability considerations and should be clearly differentiated from
components used in general purpose applications.
than their rated values.
If an AC voltage is loaded on a DC voltage, the sum of the two
peak voltages should be lower than the rated value of the ca-
pacitor chosen. For a circuit where both an AC and a pulse
voltage may be present, the sum of their peak voltages should
also be lower than the capacitor's rated voltage.
reliability of capacitors might be reduced if either a high fre-
quency AC voltage or a pulse voltage having rapid rise time is
present in the circuit.
der used (size of fillet) can directly affect capacitor performance.
Therefore, the following items must be carefully considered in
the design of solder land patterns:
(1) The amount of solder applied can affect the ability of chips
(2) When more than one part is jointly soldered onto the same
to withstand mechanical stresses which may lead to break-
ing or cracking. Therefore, when designing land-patterns
it is necessary to consider the appropriate size and con-
figuration of the solder pads which in turn determines the
amount of solder necessary to form the fillets.
land or pad, the pad must be designed so that each
component's soldering point is separated by solder-re-
sist.
