Recommended PCB Design for SMT Land-Pattems
When chips are mounted on a PCB, the amount of solder used (size of fillet) can directly affect chip 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 to withstand mechanical stresses which may lead to breaking or cracking.
Therefore, when designing land-patterns it is necessary to consider the appropriate size and configuration of the solder pads which in
turn determines the amount of solder necessary to form the fillets.
(2) When more than one part is jointly soldered onto the same land or pad, the pad must be designed that each component’s soldering
Point is separated by solder-resist
Recommended land dimensions please refer to product specification.
