Going solderless – Press-Fit capacitors bring multiple benefits to circuit assembly
Solderless assembly of electronic components can deliver significant benefits in terms of simplicity, repeatability and some key electrical and mechanical considerations. However, to be acceptable, technologies such as Press-Fit need to satisfy stringent operational and performance requirements stipulated for the specific application and by standards bodies such as IEC. MARYANN FULTON, KEMET The need for […]
