Strain Gauge: Stress Testing on Printed Circuits Boardss
Web2222A: Sectional design standard for rigid PCB. Used in conjunction with IPC-2221, IPC-2222 sets specific requirements for designing rigid printed circuit boards and other forms of component mounting and interconnection structures. This standard applies to single-sided PCBs, double-sided PCBs, or multilayer PCB boards. WebStrain gage measurement is a reliable method of finding and resolving excessive strains on a PCB, and should be implemented in the fixture preventive maintenance routine. Strain gage tests must be conducted after every modification that can affect the strain in the fixture. WebThe suggested procedures enables board manufacturers to conduct required strain gage testing independently, and provides a quantitative method for measuring board flexure, and assessing risk levels. The topics covered include: Test setup and equipment; requirements; Strain measurement; Report format. homes for sale in the legends middletown de
